North Korea-linked threat actors are conducting Operation Conflict Compass, targeting individuals and organizations focused on Ukraine using spear-phishing emails with malicious ZIP attachments. These contain LNK files disguised as PDFs with themes related to Russia-Ukraine peace plans, Ukrainian research, and geopolitical issues. When executed, the shortcuts retrieve malicious files from GitHub, deploying VBScript to establish persistence via scheduled tasks and delivering VelvetCake, a lightweight PowerShell-based task runner. VelvetCake contacts command-and-control infrastructure to download and execute additional scripts that perform reconnaissance, collect system information, enumerate security software, and capture screenshots. The campaign also utilized trojanized Zoom installers and leveraged infrastructure in South Korea and Ukraine, with activity observed since early August 2026 targeting diplomatic entities, think tanks, and NGOs.

In 2026, the DPRK-sponsored Lazarus subgroup TraderTraitor continued campaigns targeting cryptocurrency entities, including a high-profile attack on LayerZero resulting in $292 million theft from KelpDAO. Following this disclosure, an additional victim was identified: a smaller IT services provider in India with no cryptocurrency connections. The compromise involved a DevOps engineer targeted through fake job interview lures containing weaponized Terraform coding projects. Malicious GitHub repositories used typosquatted provider domains to deliver macOS backdoors FLATROOF and ROOFDECK when victims executed terraform init. The backdoors enabled reconnaissance, credential theft, and cloud environment escalation. One day after LayerZero's public disclosure, attackers deployed an updated stripped version of ROOFDECK and removed earlier implants. Activity continued until June 2026, suggesting the threat actor ultimately abandoned the intrusion after determining insufficient value from the smaller target.

The Kimsuky threat group has integrated artificial intelligence capabilities into its attack operations, establishing local large language model environments using Ollama, GPT4All, and Msty. Evidence indicates the group is accumulating technologies to incorporate AI across attack operations, including AI-generated decoy documents and retrieval-augmented generation for document analysis. The campaign, dubbed Operation GitPower, continues targeting foreign diplomatic missions and sectors including military, security, and virtual assets. Attacks utilize malicious LNK files contained in ZIP archives, executing obfuscated PowerShell scripts that abuse Git-based repositories as command-and-control infrastructure. The group distributes encrypted AsyncRAT payloads disguised as image files through GitHub. Linguistic indicators including North Korean vocabulary patterns such as "싸이트", "가입리력", and "로출되였는지" support attribution to North Korean state-sponsored operations under the Reconnaissance General Bureau.

Between April and May 2026, a likely North Korean threat actor conducted phishing campaigns targeting developers across nearly 100 organizations in finance, cryptocurrency, education, and technology sectors. The attacks used recruitment and code review themes, delivering emails with links to actor-controlled GitHub repositories hosting malicious scripts. The infection chain exploited Visual Studio Code workflows and deployed malicious Visual Studio Extensions (VSIX) requiring minimal user interaction. Cross-platform malware was executed on macOS, Linux, and Windows systems, including the open-source Overlord framework. The campaigns specifically targeted developer assets including API tokens, cryptocurrency wallets, and credentials. Attackers employed fake company personas and professional-looking repositories masquerading as legitimate cryptocurrency and blockchain projects to establish credibility and lure victims.

Void Dokkaebi, also known as Famous Chollima, has evolved its operations into a self-propagating supply chain threat targeting software developers. The North Korea-aligned group uses fabricated job interviews to lure developers into cloning malicious repositories. Once compromised, the victim's machine becomes an infection vector through two mechanisms: malicious VS Code task configurations that execute automatically when workspaces are opened, and active injection of obfuscated JavaScript into source code files with Git history tampering to conceal modifications. This creates a worm-like propagation chain where each compromised developer seeds new repositories with infection vectors. Analysis in March 2026 identified over 750 infected repositories, with contamination reaching organizations including DataStax and Neutralinojs. The campaign delivers payloads via blockchain infrastructure including Tron, Aptos, and Binance Smart Chain, deploying variants of DEV#POPPER RAT and other tools to steal cryptocurre...

Microsoft Threat Intelligence uncovered a macOS-focused cyber campaign by North Korean threat actor Sapphire Sleet utilizing social engineering to compromise systems. The attack chain begins with a malicious AppleScript file disguised as a Zoom SDK update, which executes cascading payloads through curl-to-osascript chains. The campaign deploys multiple backdoors including com.apple.cli, services, icloudz, and com.google.chromes.updaters for persistence and command execution. Credential harvesting occurs through fake system dialogs that mimic legitimate macOS password prompts. The threat actor bypasses Transparency, Consent, and Control protections by directly manipulating the TCC database, enabling extensive data exfiltration targeting cryptocurrency wallets, browser credentials, Telegram sessions, SSH keys, and Apple Notes. Operations focus on cryptocurrency, finance, and blockchain organizations with the primary objective of stealing digital assets.

APT37 conducted a sophisticated social engineering campaign utilizing Facebook accounts claiming locations in Pyongyang and Pyongsong, North Korea, to conduct reconnaissance and build trust with targets. After establishing relationships through Facebook Messenger, the threat actor migrated conversations to Telegram and employed pretexting tactics, claiming to share encrypted PDF documents containing military weapons information. Victims were persuaded to install a tampered Wondershare PDFelement installer that executed embedded shellcode for initial compromise. The attack chain delivered follow-on commands through a JPG-disguised payload hosted on a compromised Japanese real estate website. The malware abused Zoho WorkDrive OAuth2 APIs as C2 channels, exfiltrating screenshots, documents, system information, and audio files. The campaign employed multiple evasion techniques including code cave injection, process hollowing into legitimate dism.exe, XOR encryption layers, and fileless in-memory execution.

A sophisticated fake recruitment campaign named 'graphalgo' has been active since May 2025, targeting JavaScript and Python developers in the cryptocurrency sector. Attackers approach victims through LinkedIn, Facebook, and Reddit with fabricated job opportunities from fake blockchain companies like Veltrix Capital. The campaign uses malicious dependencies hidden in npm and PyPI packages, delivered through coding test repositories on GitHub. Notable is the bigmathutils package that accumulated over 10,000 downloads before its malicious version was released. The operation deploys a remote access trojan (RAT) with token-protected C2 communication, file manipulation capabilities, and functionality to detect the Metamask browser extension, indicating focus on cryptocurrency theft. The modular campaign design allows threat actors to maintain backend infrastructure while easily replacing compromised frontend elements.

Between April 6-9, 2026, multiple obfuscated malicious npm packages were identified as variants of the OtterCookie infostealer attributed to North Korean threat actors. The campaign employs a two-layer distribution strategy where benign wrapper packages clone legitimate libraries like big.js while pulling malicious dependencies containing the actual payload. Five malicious packages were identified, each containing obfuscated JavaScript files that execute via postinstall hooks. The toolchain steals credentials, files including Solana wallets and environment configurations, and exfiltrates data to Vercel-hosted C2 infrastructure. On Linux systems, it establishes persistence through SSH backdoor installation. The infrastructure overlaps with documented OtterCookie operations and connects to broader DPRK campaigns including Contagious Interview and Contagious Trader, demonstrating continued evolution in North Korean software supply chain attacks targeting developers.

A North Korean threat operation has published malicious packages across npm, PyPI, Go Modules, crates.io, and Packagist, impersonating legitimate developer tooling. The campaign uses GitHub aliases including golangorg and aokisasakidev to distribute staged malware loaders that contact actor-controlled infrastructure, retrieve payloads from Google Drive, and deliver platform-specific second-stage malware. The loaders are hidden behind normal-looking API functions in logging and utility libraries. Windows variants include full remote access trojans with capabilities for shell execution, keylogging, browser and wallet theft, sensitive file collection, and AnyDesk deployment. The operation demonstrates coordinated cross-ecosystem supply chain attacks with shared infrastructure patterns, reused extraction directories, and consistent staging logic across multiple programming languages.
