T1310	Acquire or compromise 3rd party signing certificates	Code signing is the process of digitally signing executables or scripts to confirm the software author and guarantee that the code has not been altered or corrupted. Users may trust a signed piece of code more than an unsigned piece of code even if they don't know who issued the certificate or who the author is.
T1332	Acquire or compromise 3rd party signing certificates	Code signing is the process of digitally signing executables and scripts to confirm the software author and guarantee that the code has not been altered or corrupted. Users may trust a signed piece of code more than an unsigned piece of code even if they don't know who issued the certificate or who the author is.
T1266	Acquire OSINT data sets and information	Open source intelligence (OSINT) provides free, readily available information about a target while providing the target no indication they are of interest. Such information can assist an adversary in crafting a successful approach for compromise.

T1303	Analyze presence of outsourced capabilities	Outsourcing, the arrangement of one company providing goods or services to another company for something that could be done in-house, provides another avenue for an adversary to target. Businesses often have networks, portals, or other technical connections between themselves and their outsourced/partner organizations that could be exploited. Additionally, outsourced/partner organization information could provide opportunities for phishing.
T1295	Analyze social and business relationships, interests, and affiliations	Social media provides insight into the target's affiliations with groups and organizations. Certification information can explain their technical associations and professional associations. Personal information can provide data for exploitation or even blackmail.
T1306	Anonymity services	Anonymity services reduce the amount of information available that can be used to track an adversary's activities. Multiple options are available to hide activity, limit tracking, and increase anonymity.
T1236	Assess current holdings, needs, and wants	Analysts assess current information available against requirements that outline needs and wants as part of the research baselining process to begin satisfying a requirement.
T1229	Assess KITs/KIQs benefits	Key Intelligence Topics (KITs) and Key Intelligence Questions (KIQs) may be further subdivided to focus on political, economic, diplomatic, military, financial, or intellectual property categories. An adversary may specify KITs or KIQs in this manner in order to understand how the information they are pursuing can have multiple uses and to consider all aspects of the types of information they need to target for a particular purpose. KIT.
T1224	Assess leadership areas of interest	Leadership assesses the areas of most interest to them and generates Key Intelligence Topics (KIT) or Key Intelligence Questions (KIQ). For example, an adversary knows from open and closed source reporting that cyber is of interest, resulting in it being a KIT.
T1299	Assess opportunities created by business deals	During mergers, divestitures, or other period of change in joint infrastructure or business processes there may be an opportunity for exploitation. During this type of churn, unusual requests, or other non standard practices may not be as noticeable.
T1302	Assess security posture of physical locations	Physical access may be required for certain types of adversarial actions.
T1296	Assess targeting options	An adversary may assess a target's operational security (OPSEC) practices in order to identify targeting options. A target may share different information in different settings or be more of less cautious in different environments.
T1298	Assess vulnerability of 3rd party vendors	Once a 3rd party vendor has been identified as being of interest it can be probed for vulnerabilities just like the main target would be.
T1238	Assign KITs, KIQs, and/or intelligence requirements	Once generated, Key Intelligence Topics (KITs), Key Intelligence Questions (KIQs), and/or intelligence requirements are assigned to applicable agencies and/or personnel. For example, an adversary may decide nuclear energy requirements should be assigned to a specific organization based on their mission.
T1228	Assign KITs/KIQs into categories	Leadership organizes Key Intelligence Topics (KITs) and Key Intelligence Questions (KIQs) into three types of categories and creates more if necessary. An example of a description of key players KIT would be when an adversary assesses the cyber defensive capabilities of a nation-state threat actor.
T1347	Build and configure delivery systems	Delivery systems are the infrastructure used by the adversary to host malware or other tools used during exploitation. Building and configuring delivery systems may include multiple activities such as registering domain names, renting hosting space, or configuring previously exploited environments.
T1349	Build or acquire exploits	An exploit takes advantage of a bug or vulnerability in order to cause unintended or unanticipated behavior to occur on computer hardware or software. The adversary may use or modify existing exploits when those exploits are still relevant to the environment they are trying to compromise.
T1341	Build social network persona	For attacks incorporating social engineering the utilization of an on-line persona is important. These personas may be fictitious or impersonate real people. The persona may exist on a single site or across multiple sites (Facebook, LinkedIn, Twitter, Google+, etc.).
T1328	Buy domain name	Domain Names are the human readable names used to represent one or more IP addresses. They can be purchased or, in some cases, acquired for free.
T1352	C2 protocol development	Command and Control (C2 or C&C) is a method by which the adversary communicates with malware. An adversary may use a variety of protocols and methods to execute C2 such as a centralized server, peer to peer, IRC, compromised web sites, or even social media.
T1391	Choose pre-compromised mobile app developer account credentials or signing keys	The adversary can use account credentials or signing keys of an existing mobile app developer to publish malicious updates of existing mobile apps to an application store, or to abuse the developer's identity and reputation to publish new malicious apps. Many mobile devices are configured to automatically install new versions of already-installed apps.
T1343	Choose pre-compromised persona and affiliated accounts	For attacks incorporating social engineering the utilization of an on-line persona is important. Utilizing an existing persona with compromised accounts may engender a level of trust in a potential victim if they have a relationship, or knowledge of, the compromised persona.
T1321	Common, high volume protocols and software	Certain types of traffic (e.g., Twitter14, HTTP) are more commonly used than others. Utilizing more common protocols and software may make an adversary's traffic more difficult to distinguish from legitimate traffic.
T1312	Compromise 3rd party infrastructure to support delivery	Instead of buying, leasing, or renting infrastructure an adversary may compromise infrastructure and use it for some or all of the attack cycle.
T1334	Compromise 3rd party infrastructure to support delivery	Instead of buying, leasing, or renting infrastructure an adversary may compromise infrastructure and use it for some or all of the attack cycle.
T1354	Compromise 3rd party or closed-source vulnerability/exploit information	There is usually a delay between when a vulnerability or exploit is discovered and when it is made public. An adversary may target the systems of those known to research vulnerabilities in order to gain that knowledge for use during a different attack.
T1254	Conduct active scanning	Active scanning is the act of sending transmissions to end nodes, and analyzing the responses, in order to identify information about the communications system.
T1226	Conduct cost/benefit analysis	Leadership conducts a cost/benefit analysis that generates a compelling need for information gathering which triggers a Key Intelligence Toptic (KIT) or Key Intelligence Question (KIQ).

T1320	Data Hiding	Certain types of traffic (e.g., DNS tunneling, header inject) allow for user-defined fields. These fields can then be used to hide data. In addition to hiding data in network protocols, steganography techniques can be used to hide data in images or other file formats. Detection can be difficult unless a particular signature is already known.
T1230	Derive intelligence requirements	Leadership or key decision makers may derive specific intelligence requirements from Key Intelligence Topics (KITs) or Key Intelligence Questions (KIQs). Specific intelligence requirements assist analysts in gathering information to establish a baseline of information about a topic or question and collection managers to clarify the types of information that should be collected to satisfy the requirement.
T1284	Determine 3rd party infrastructure services	A wide variety of cloud, virtual private services, hosting, compute, and storage solutions are available as 3rd party infrastructure services. These services could provide an adversary with another avenue of approach or compromise.
T1260	Determine 3rd party infrastructure services	Infrastructure services includes the hardware, software, and network resources required to operate a communications environment. This infrastructure can be managed by a 3rd party rather than being managed by the owning organization.
T1245	Determine approach/attack vector	The approach or attack vector outlines the specifics behind how the adversary would like to attack the target. As additional information is known through the other phases of PRE-ATT&CK, an adversary may update the approach or attack vector.
T1285	Determine centralization of IT management	Determining if a "corporate" help desk exists, the degree of access and control it has, and whether there are "edge" units that may have different support processes and standards.
T1250	Determine domain and IP address space	Domain Names are the human readable names used to represent one or more IP addresses. IP addresses are the unique identifier of computing devices on a network. Both pieces of information are valuable to an adversary who is looking to understand the structure of a network.
T1259	Determine external network trust dependencies	Network trusts enable communications between different networks with specific accesses and permissions. Network trusts could include the implementation of domain trusts or the use of virtual private networks (VPNs).
T1258	Determine firmware version	Firmware is permanent software programmed into the read-only memory of a device. As with other types of software, firmware may be updated over time and have multiple versions.
T1243	Determine highest level tactical element	From a tactical viewpoint, an adversary could potentially have a primary and secondary level target. The primary target represents the highest level tactical element the adversary wishes to attack. For example, the corporate network within a corporation or the division within an agency.
T1242	Determine operational element	If going from strategic down to tactical or vice versa, an adversary would next consider the operational element. For example, the specific company within an industry or agency within a government.
T1282	Determine physical locations	Physical locality information may be used by an adversary to shape social engineering attempts (language, culture, events, weather, etc.) or to plan for physical actions such as dumpster diving or attempting to access a facility.
T1244	Determine secondary level tactical element	The secondary level tactical element the adversary seeks to attack is the specific network or area of a network that is vulnerable to attack. Within the corporate network example, the secondary level tactical element might be a SQL server or a domain controller with a known vulnerability.
T1241	Determine strategic target	An adversary undergoes an iterative target selection process that may begin either broadly and narrow down into specifics (strategic to tactical) or narrowly and expand outward (tactical to strategic). As part of this process, an adversary may determine a high level target they wish to attack. One example of this may be a particular country, government, or commercial sector.
T1227	Develop KITs/KIQs	Leadership derives Key Intelligence Topics (KITs) and Key Intelligence Questions (KIQs) from the areas of most interest to them. KITs are an expression of management's intelligence needs with respect to early warning, strategic and operational decisions, knowing the competition, and understanding the competitive situation. KIQs are the critical questions aligned by KIT which provide the basis for collection plans, create a context for analytic work, and/or identify necessary external operations.
T1342	Develop social network persona digital footprint	Both newly built personas and pre-compromised personas may require development of additional documentation to make them seem real. This could include filling out profile information, developing social networks, or incorporating photos.
T1350	Discover new exploits and monitor exploit-provider forums	An exploit takes advantage of a bug or vulnerability in order to cause unintended or unanticipated behavior to occur on computer hardware or software. The adversary may need to discover new exploits when existing exploits are no longer relevant to the environment they are trying to compromise. An adversary may monitor exploit provider forums to understand the state of existing, as well as newly discovered, exploits.
T1255	Discover target logon/email address format	Email addresses, logon credentials, and other forms of online identification typically share a common format. This makes guessing other credentials within the same domain easier. For example if a known email address is [email protected] it is likely that others in the company will have an email in the same format.
T1379	Disseminate removable media	Removable media containing malware can be injected in to a supply chain at large or small scale. It can also be physically placed for someone to find or can be sent to someone in a more targeted manner. The intent is to have the user utilize the removable media on a system where the adversary is trying to gain access.
T1394	Distribute malicious software development tools	An adversary could distribute malicious software development tools (e.g., compiler) that hide malicious behavior in software built using the tools.

T1364	Friend/Follow/Connect to targets of interest	A form of social engineering designed build trust and to lay the foundation for future interactions or attacks.
T1234	Generate analyst intelligence requirements	Analysts may receive Key Intelligence Topics (KITs) and Key Intelligence Questions (KIQs) from leadership or key decision makers and generate intelligence requirements to articulate intricacies of information required on a topic or question.
T1365	Hardware or software supply chain implant	During production and distribution, the placement of software, firmware, or a CPU chip in a computer, handheld, or other electronic device that enables an adversary to gain illegal entrance.
T1314	Host-based hiding techniques	Host based hiding techniques are designed to allow an adversary to remain undetected on a machine upon which they have taken action. They may do this through the use of static linking of binaries, polymorphic code, exploiting weakness in file formats, parsers, or self-deleting code.
T1233	Identify analyst level gaps	Analysts identify gap areas that generate a compelling need to generate a Key Intelligence Topic (KIT) or Key Intelligence Question (KIQ).
T1280	Identify business processes/tempo	Understanding an organizations business processes and tempo may allow an adversary to more effectively craft social engineering attempts or to better hide technical actions, such as those that generate network traffic.
T1272	Identify business relationships	Business relationship information includes the associates of a target and may be discovered via social media sites such as LinkedIn or public press releases announcing new partnerships between organizations or people (such as key hire announcements in industry articles). This information may be used by an adversary to shape social engineering attempts (exploiting who a target expects to hear from) or to plan for technical actions such as exploiting network trust relationship.
T1283	Identify business relationships	Business relationship information may be used by an adversary to shape social engineering attempts (exploiting who a target expects to hear from) or to plan for technical actions such as exploiting network trust relationship.
T1225	Identify gap areas	Leadership identifies gap areas that generate a compelling need to generate a Key Intelligence Topic (KIT) or Key Intelligence Question (KIQ).
T1270	Identify groups/roles	Personnel internally to a company may belong to a group or maintain a role with electronic specialized access, authorities, or privilege that make them an attractive target for an adversary. One example of this is a system administrator.
T1248	Identify job postings and needs/gaps	Job postings, on either company sites, or in other forums, provide information on organizational structure and often provide contact information for someone within the organization. This may give an adversary information on technologies within the organization which could be valuable in attack or provide insight in to possible security weaknesses or limitations in detection or protection mechanisms.
T1278	Identify job postings and needs/gaps	Job postings, on either company sites, or in other forums, provide information on organizational structure, needs, and gaps in an organization. This may give an adversary an indication of weakness in an organization (such as under-resourced IT shop). Job postings can also provide information on an organizations structure which could be valuable in social engineering attempts.
T1267	Identify job postings and needs/gaps	Job postings, on either company sites, or in other forums, provide information on organizational structure and often provide contact information for someone within the organization. This may give an adversary information on people within the organization which could be valuable in social engineering attempts.
T1269	Identify people of interest	The attempt to identify people of interest or with an inherent weakness for direct or indirect targeting to determine an approach to compromise a person or organization. Such targets may include individuals with poor OPSEC practices or those who have a trusted relationship with the intended target.
T1271	Identify personnel with an authority/privilege	Personnel internally to a company may have non-electronic specialized access, authorities, or privilege that make them an attractive target for an adversary. One example of this is an individual with financial authority to authorize large transactions. An adversary who compromises this individual might be able to subvert large dollar transfers.
T1348	Identify resources required to build capabilities	As with legitimate development efforts, different skill sets may be required for different phases of an attack. The skills needed may be located in house, can be developed, or may need to be contracted out.
T1263	Identify security defensive capabilities	Security defensive capabilities are designed to stop or limit unauthorized network traffic or other types of accesses.
T1274	Identify sensitive personnel information	An adversary may identify sensitive personnel information not typically posted on a social media site, such as address, marital status, financial history, and law enforcement infractions. This could be conducted by searching public records that are frequently available for free or at a low cost online.
T1276	Identify supply chains	Supply chains include the people, processes, and technologies used to move a product or service from a supplier to a consumer. Understanding supply chains may provide an adversary with opportunities to exploit organizational relationships.
T1246	Identify supply chains	Supply chains include the people, processes, and technologies used to move a product or service from a supplier to a consumer. Understanding supply chains may provide an adversary with opportunities to exploit the technology or interconnections that are part of the supply chain.
T1265	Identify supply chains	Supply chains include the people, processes, and technologies used to move a product or service from a supplier to a consumer. Understanding supply chains may provide an adversary with opportunities to exploit the people, their positions, and relationships, that are part of the supply chain.
T1264	Identify technology usage patterns	Technology usage patterns include identifying if users work offsite, connect remotely, or other possibly less restricted/secured access techniques.
T1389	Identify vulnerabilities in third-party software libraries	Many applications use third-party software libraries, often without full knowledge of the behavior of the libraries by the application developer. For example, mobile applications often incorporate advertising libraries to generate revenue for the application developer. Vulnerabilities in these third-party libraries could potentially be exploited in any application that uses the library, and even if the vulnerabilities are fixed, many applications may still use older, vulnerable versions of the library.
T1256	Identify web defensive services	An adversary can attempt to identify web defensive services as CloudFlare, IPBan, and Snort. This may be done by passively detecting services, like CloudFlare routing, or actively, such as by purposefully tripping security defenses.
T1336	Install and configure hardware, network, and systems	An adversary needs the necessary skills to set up procured equipment and software to create their desired infrastructure.
T1252	Map network topology	A network topology is the arrangement of the various elements of a network (e.g., servers, workstations, printers, routers, firewalls, etc.). Mapping a network allows an adversary to understand how the elements are connected or related.
T1273	Mine social media	An adversary may research available open source information about a target commonly found on social media sites such as Facebook, Instagram, or Pinterest. Social media is public by design and provides insight into the interests and potentially inherent weaknesses of a target for exploitation by the adversary.
T1257	Mine technical blogs/forums	Technical blogs and forums provide a way for technical staff to ask for assistance or troubleshoot problems. In doing so they may reveal information such as operating system (OS), network devices, or applications in use.
T1322	Misattributable credentials	The use of credentials by an adversary with the intent to hide their true identity and/or portray them self as another person or entity. An adversary may use misattributable credentials in an attack to convince a victim that credentials are legitimate and trustworthy when this is not actually the case.

T1313	Obfuscation or cryptography	Obfuscation is the act of creating communications that are more difficult to understand. Encryption transforms the communications such that it requires a key to reverse the encryption.
T1392	Obtain Apple iOS enterprise distribution key pair and certificate	The adversary can obtain an Apple iOS enterprise distribution key pair and certificate and use it to distribute malicious apps directly to Apple iOS devices without the need to publish the apps to the Apple App Store (where the apps could potentially be detected).
T1396	Obtain booter/stressor subscription	Configure and setup booter/stressor services, often intended for server stress testing, to enable denial of service attacks.
T1251	Obtain domain/IP registration information	For a computing resource to be accessible to the public, domain names and IP addresses must be registered with an authorized organization.
T1281	Obtain templates/branding materials	Templates and branding materials may be used by an adversary to add authenticity to social engineering message.
T1346	Obtain/re-use payloads	A payload is the part of the malware which performs a malicious action. The adversary may re-use payloads when the needed capability is already available.
T1390	OS-vendor provided communication channels	Google and Apple provide Google Cloud Messaging and Apple Push Notification Service, respectively, services designed to enable efficient communication between third-party mobile app backend servers and the mobile apps running on individual devices. These services maintain an encrypted connection between every mobile device and Google or Apple that cannot easily be inspected and must be allowed to traverse networks as part of normal device operation. These services could be used by adversaries for communication to compromised mobile devices.
T1363	Port redirector	Redirecting a communication request from one address and port number combination to another. May be set up to obfuscate the final location of communications that will occur in later stages of an attack.
T1353	Post compromise tool development	After compromise, an adversary may utilize additional tools to facilitate their end goals. This may include tools to further explore the system, move laterally within a network, exfiltrate data, or destroy data.
T1305	Private whois services	Every domain registrar maintains a publicly viewable database that displays contact information for every registered domain. Private 'whois' services display alternative information, such as their own company data, rather than the owner of the domain.
T1335	Procure required equipment and software	An adversary will require some physical hardware and software. They may only need a lightweight set-up if most of their activities will take place using on-line infrastructure. Or, they may need to build extensive infrastructure if they want to test, communicate, and control other aspects of their activities on their own systems.
T1304	Proxy/protocol relays	Proxies act as an intermediary for clients seeking resources from other systems. Using a proxy may make it more difficult to track back the origin of a network communication.
T1239	Receive KITs/KIQs and determine requirements	Applicable agencies and/or personnel receive intelligence requirements and evaluate them to determine sub-requirements related to topics, questions, or requirements. For example, an adversary's nuclear energy requirements may be further divided into nuclear facilities versus nuclear warhead capabilities.
T1235	Receive operator KITs/KIQs tasking	Analysts may receive intelligence requirements from leadership and begin research process to satisfy a requirement. Part of this process may include delineating between needs and wants and thinking through all the possible aspects associating with satisfying a requirement.
T1351	Remote access tool development	A remote access tool (RAT) is a piece of software that allows a remote user to control a system as if they had physical access to that system. An adversary may utilize existing RATs, modify existing RATs, or create their own RAT.
T1291	Research relevant vulnerabilities/CVEs	Common Vulnerability Enumeration (CVE) is a dictionary of publicly known information about security vulnerabilities and exposures. An adversary can use this information to target specific software that may be vulnerable.
T1290	Research visibility gap of security vendors	If an adversary can identify which security tools a victim is using they may be able to identify ways around those tools.
T1358	Review logs and residual traces	Execution of code and network communications often result in logging or other system or network forensic artifacts. An adversary can run their code to identify what is recorded under different conditions. This may result in changes to their code or adding additional actions (such as deleting a record from a log) to the code.
T1317	Secure and protect infrastructure	An adversary may secure and protect their infrastructure just as defenders do. This could include the use of VPNs, security software, logging and monitoring, passwords, or other defensive measures.
T1340	Shadow DNS	The process of gathering domain account credentials in order to silently create subdomains pointed at malicious servers without tipping off the actual owner.
T1397	Spearphishing for Information	Spearphishing for information is a specific variant of spearphishing. Spearphishing for information is different from other forms of spearphishing in that it it doesn't leverage malicious code. All forms of spearphishing are elctronically delivered social engineering targeted at a specific individual, company, or industry. Spearphishing for information is an attempt to trick targets into divulging information, frequently credentials, without involving malicious code. Spearphishing for information frequently involves masquerading as a source with a reason to collect information (such as a system administrator or a bank) and providing a user with a website link to visit. The given website often closely resembles a legitimate site in appearance and has a URL containing elements from the real site. From the fake website, information is gathered in web forms and sent to the attacker. Spearphishing for information may also try to obtain information directly through the exchange of emails, instant messengers or other electronic conversation means.
T1337	SSL certificate acquisition for domain	Certificates are designed to instill trust. They include information about the key, information about its owner's identity, and the digital signature of an entity that has verified the certificate's contents are correct. If the signature is valid, and the person examining the certificate trusts the signer, then they know they can use that key to communicate with its owner. Acquiring a certificate for a domain name similar to one that is expected to be trusted may allow an adversary to trick a user in to trusting the domain (e.g., vvachovia instead of Wachovia -- homoglyphs).

For example, an adversary's nuclear energy requirements may be further divided into nuclear facilities versus nuclear warhead capabilities.

T1235

Receive operator KITs/KIQs tasking

Analysts may receive intelligence requirements from leadership and begin research process to satisfy a requirement. Part of this process may include delineating between needs and wants and thinking through all the possible aspects associating with satisfying a requirement.

T1351

Remote access tool development

A remote access tool (RAT) is a piece of software that allows a remote user to control a system as if they had physical access to that system. An adversary may utilize existing RATs, modify existing RATs, or create their own RAT.

T1291

Research relevant vulnerabilities/CVEs

Common Vulnerability Enumeration (CVE) is a dictionary of publicly known information about security vulnerabilities and exposures. An adversary can use this information to target specific software that may be vulnerable.

T1290

Research visibility gap of security vendors

If an adversary can identify which security tools a victim is using they may be able to identify ways around those tools.

T1358

Review logs and residual traces

Execution of code and network communications often result in logging or other system or network forensic artifacts. An adversary can run their code to identify what is recorded under different conditions. This may result in changes to their code or adding additional actions (such as deleting a record from a log) to the code.

T1317

Secure and protect infrastructure

An adversary may secure and protect their infrastructure just as defenders do. This could include the use of VPNs, security software, logging and monitoring, passwords, or other defensive measures.

T1340

Shadow DNS

The process of gathering domain account credentials in order to silently create subdomains pointed at malicious servers without tipping off the actual owner.

T1397

Spearphishing for Information

Spearphishing for information is a specific variant of spearphishing. Spearphishing for information is different from other forms of spearphishing in that it it doesn't leverage malicious code. All forms of spearphishing are elctronically delivered social engineering targeted at a specific individual, company, or industry. Spearphishing for information is an attempt to trick targets into divulging information, frequently credentials, without involving malicious code. Spearphishing for information frequently involves masquerading as a source with a reason to collect information (such as a system administrator or a bank) and providing a user with a website link to visit. The given website often closely resembles a legitimate site in appearance and has a URL containing elements from the real site. From the fake website, information is gathered in web forms and sent to the attacker. Spearphishing for information may also try to obtain information directly through the exchange of emails, instant messengers or other electronic conversation means.

T1337

SSL certificate acquisition for domain

Certificates are designed to instill trust. They include information about the key, information about its owner's identity, and the digital signature of an entity that has verified the certificate's contents are correct. If the signature is valid, and the person examining the certificate trusts the signer, then they know they can use that key to communicate with its owner. Acquiring a certificate for a domain name similar to one that is expected to be trusted may allow an adversary to trick a user in to trusting the domain (e.g., vvachovia instead of Wachovia -- homoglyphs).

T1338

SSL certificate acquisition for trust breaking

Fake certificates can be acquired by legal process or coercion. Or, an adversary can trick a Certificate Authority into issuing a certificate. These fake certificates can be used as a part of Man-in-the-Middle attacks.

T1237

Submit KITs, KIQs, and intelligence requirements

Once they have been created, intelligence requirements, Key Intelligence Topics (KITs), and Key Intelligence Questions (KIQs) are submitted into a central management system.

T1240

Task requirements

Once divided into the most granular parts, analysts work with collection managers to task the collection management system with requirements and sub-requirements.

T1393

Test ability to evade automated mobile application security analysis performed by app stores

Many mobile devices are configured to only allow applications to be installed from the mainstream vendor app stores (e.g., Apple App Store and Google Play Store). An adversary can submit multiple code samples to these stores deliberately designed to probe the stores' security analysis capabilities, with the goal of determining effective techniques to place malicious applications in the stores that could then be delivered to targeted devices.

T1356

Test callback functionality

Callbacks are malware communications seeking instructions. An adversary will test their malware to ensure the appropriate instructions are conveyed and the callback software can be reached.

T1357

Test malware in various execution environments

Malware may perform differently on different platforms (computer vs handheld) and different operating systems (Ubuntu vs OS X), and versions (Windows 7 vs 10) so malicious actors will test their malware in the environment(s) where they most expect it to be executed.

T1359

Test malware to evade detection

An adversary can run their code on systems with cyber security protections, such as antivirus products, in place to see if their code is detected. They can also test their malware on freely available public services.

T1360

Test physical access

An adversary can test physical access options in preparation for the actual attack. This could range from observing behaviors and noting security precautions to actually attempting access.

T1292

Test signature detection

An adversary can test the detections of malicious emails or files by using publicly available services, such as virus total, to see if their files or emails cause an alert. They can also use similar services that are not openly available and don't publicly publish results or they can test on their own internal infrastructure.

T1361

Test signature detection for file upload/email filters

An adversary can test their planned method of attack against existing security products such as email filters or intrusion detection sensors (IDS).

T1362

Upload, install, and configure software/tools

An adversary may stage software and tools for use during later stages of an attack. The software and tools may be placed on systems legitimately in use by the adversary or may be placed on previously compromised infrastructure.

T1327

Use multiple DNS infrastructures

A technique used by the adversary similar to Dynamic DNS with the exception that the use of multiple DNS infrastructures likely have whois records.
