T1683.001: Written Content
Adversaries may create or tailor written materials to support targeting and malicious operations. Content may include phishing lures, fraudulent financial communications, fabricated job postings, fabricated employment credentials and documentation, decoy documents, social media persona content, and supporting narratives used to sustain fabricated personas over time.[1][2] Content may be authored manually, commissioned through third parties, or produced using AI-assisted tools.
Written materials may impersonate legitimate government correspondence, diplomatic communications, or internal organizational documents to support targeting efforts. AI-assisted tools may also be used to tailor content to specific targets, industries, or regions. For example, adversaries may leverage AI to translate content into a target's native language or mimic the communication style of trusted senders.
Written content produced through these methods may be used in support of other techniques, such as Phishing, Spearphishing via Service, Phishing for Information, Internal Spearphishing, Social Engineering, Financial Theft, or Establish Accounts.
Written content does not include malicious code or scripts; for development of malicious code and scripts, see Develop Capabilities.

Executive priority
T1683.001: Written Content is an official MITRE ATT&CK technique. Glexia treats it as defensive behavior context for prioritizing monitoring, control validation, and response planning without using the object by itself as an attribution claim.
Technical view
Security teams should validate T1683.001: Written Content by reviewing the official ATT&CK relationships, mapped tactics (resource-development), supported platforms (PRE), and available local telemetry before making detection or mitigation decisions.
Likely telemetry
- Official ATT&CK relationships and object metadata
Detection direction
- Validate whether T1683.001: Written Content appears in your detection coverage and tabletop scenarios.
- Use the object to align executive risk language with SOC, incident response, and detection engineering work.
- Do not treat ATT&CK relationship context as attribution without corroborating evidence.
Mitigation priorities
- Map the object to existing controls and identify missing telemetry or response ownership.
- Prioritize mitigations that reduce exposure on the listed platforms and tactics.
- Review adjacent ATT&CK relationships before changing policy, detections, or reporting language.
Additional notes and limits
Baseline Glexia take generated from the official MITRE ATT&CK STIX object, source hash, tactics, platforms, and detection fields. It is safe to replace with a richer model-generated take for the same source hash later.
This baseline take is source-grounded and schema-validated, but it does not include environment-specific telemetry, incident evidence, or threat-intelligence corroboration.

Groups, software, and campaigns
G0099: APT-C-36
APT-C-36 is a suspected South American threat group that has engaged in espionage and financially motivated operations since at least 2018. APT-C-36 has targeted government institutions and entities in the financial, energy, and professional manufacturing sectors across Colombia and other Latin American countries.[1][2][3][4]
G1052: Contagious Interview
Contagious Interview is a North Korea–aligned threat group active since 2023. The group conducts both cyberespionage and financially motivated operations, including the theft of cryptocurrency and user credentials. Contagious Interview targets Windows, Linux, and macOS systems, with a particular focus on individuals engaged in software development and cryptocurrency-related activities. [1][2][3][4][5][6][7][8]
G1058: The Gentlemen
The Gentlemen is a group that maintains the The Gentlemen Ransomware-as-a-service (RaaS). The Gentlemen was first observed in mid-2025 who had posed The Gentlemen Ransomware as a closed ransomware and shortly later opened the ransomware as a RaaS to affiliates in September 2025. The Gentlemen has been affiliated with the threat group Storm-2697 and GOLD SHERWOOD.[1][2][3][4][5][6][7][8]
G1056: TeamPCP
TeamPCP is a financially-motivated, cloud-native threat group that has been active since at least September 2025. Initially focused on ransomware and cryptocurrency theft, TeamPCP shifted in early 2026 to systematic, worm-driven credential theft and software supply chain attacks targeting Continuous Integration and Continuous Delivery (CI/CD) workflows. TeamPCP has monetized access through extortion and through partnerships with ransomware actors including Vect and CipherForce.[1][2][3][4][5][6]
G1059: NIMBUS MANTICORE
NIMBUS MANTICORE is a State Sponsored cyber espionage group associated with the Iranian Regime specifically the Iranian Revolutionary Guard Corps (IRGC). NIMBUS MANTICORE has employed social engineering attacks to include HR related themes and has leveraged custom malware against its victims. NIMBUS MANTICORE has sought sensitive information in victims’ environments to include network/IT documentation, intellectual property and emails. NIMBUS MANTICORE has also leveraged compromised organizations as pivot points to access other organizations of interest. NIMBUS MANTICORE has been active since 2021 and has targeted critical infrastructure organizations to include aviation, aerospace, telecommunications and defense and information technology related organizations within the United States, Australia, Midde East and Europe.[1][2][3][4]
G0082: APT38
APT38 is a North Korean state-sponsored threat group that specializes in financial cyber operations; it has been attributed to the Reconnaissance General Bureau.[1] Active since at least 2014, APT38 has targeted banks, financial institutions, casinos, cryptocurrency exchanges, SWIFT system endpoints, and ATMs in at least 38 countries worldwide. Significant operations include the 2016 Bank of Bangladesh heist, Bancomext [2] and Banco de Chile [2], along with software supply chain compromises and destructive malware attacks.[1][2][3][4][5][6][7]
North Korean group definitions are known to have significant overlap, and some security researchers report all North Korean state-sponsored cyber activity under the name Lazarus Group instead of tracking clusters or subgroups.
S9044: Kali365
Kali365 is a Phishing-as-a-Service (PHaaS) kit first observed in April 2026 that generates victim-targeted lures across multiple operating systems to induce users into copying and pasting actor-controlled commands for local execution.[1][2][3][4] Kali365 incorporates on-demand device code generation and mirrors the copy-paste execution tradecraft associated with ClickFix. [3] Operators have used Kali365 to harvest victims' OAuth tokens and session cookies through adversary-in-the-middle (AiTM) interception, enabling account takeover.[1][5][2][3][4] Kali365 PHaaS was first observed in April 2026.[1] Kali365 has also been affiliated with other branding to include Octopi365 and Freedom365.[3]
C0064: AI-Assisted Breach of Mexico's Government Infrastructure
The AI-Assisted Breach of Mexico's Government Infrastructure is a campaign where human operators used Claude Code AI and OpenAI GPT GPT-4.1 AI to perform reconnaissance, vulnerability exploitation, privilege escalation, discovery, credential harvesting, and exfiltration operations. The attack impacted several Mexican government institutions including the Federal Tax Authority (Servicio de Administracion Tributaria), Mexico State Government (Estado de Mexico), Mexico City Civil Registry (Registro Civil de CDMX), Jalisco State Government, National Electoral Institute (Instituto Nacional Electoral), Michoacan State Government, SADM Monterrey Municipal Water Utility (Agua y Drenaje), Tamaulipas State Government, and the Mexico City Health Department (Salud CDMX). The attack resulted in the theft of large amounts of sensitive government data and civilian records. Please note that due to the breadth of this campaign, public reporting only provides select details and as a result this campaign should not be considered comprehensive.[1]
