Multiple clusters of North Korean IT workers, designated as PurpleDelta, have been identified applying to over 1,100 companies between late 2024 and early 2025, primarily targeting software, technology, staffing, consulting, and healthcare sectors. The operators maintained at least 22 fabricated personas supported by AI-generated profile photos, custom ChatGPT assistants, and fraudulent identity documents. They demonstrated sophisticated tradecraft, applying to up to 60 positions daily using multi-account management browsers and detailed tracking spreadsheets. During interviews, operators employed screen recording software and AI transcription tools to generate real-time answers, often repeating ChatGPT responses verbatim. Once employed at ten or more organizations, they recorded internal meetings, used personal devices and bank accounts, and coordinated via Telegram and Slack with facilitators who maintained company-issued hardware. This activity represents an ongoing insider threat to organizations hirin...

In February 2026, an active malware delivery campaign named Powercat was observed distributing infostealer malware disguised as utility or cheat software for popular PC games including Roblox, Minecraft, and Grand Theft Auto V. The multi-stage infection chain begins with an initial executable that profiles victims and establishes persistence, followed by a Java-based loader that deploys the final infostealer payload. The malware targets cryptocurrency wallets (Exodus, Atomic, Monero-Gui), browser data from Chromium-based applications, Discord tokens, and gaming accounts with payment information. It includes surveillance capabilities such as keylogging, webcam capture, and screen recording. The campaign particularly targets children who frequent gaming platforms and pay-to-cheat websites, with evidence suggesting collected personal information may be used for blackmail or coercion into illegal activities.

Vanta Stealer is a Python-based information stealer utilizing PyArmor protection and PyInstaller packaging to complicate defensive analysis. The malware systematically harvests credentials from Chromium-based browsers, communication platforms like Discord and Telegram, gaming applications including Steam, Riot Games, Roblox and Minecraft, cryptocurrency wallets, Mullvad VPN configurations, and sensitive documents. It performs token enrichment by validating stolen Discord credentials against the API to retrieve account details, billing information, Nitro status, and server privileges. The modular architecture downloads dedicated browser extraction utilities at runtime, maintains independence between collection modules, and generates structured inventory reports before consolidating harvested data into ZIP archives. Exfiltration occurs via HTTP POST to attacker-controlled infrastructure with victim metadata. Distribution likely occurs through social engineering campaigns involving phishing emails, trojanized...

A sophisticated macOS campaign has been discovered using a fake Zoom installer to deploy Overlord RAT, an open-source remote access framework. The attack employs a .NET-based downloader disguised as ZoomMeetings, representing an uncommon approach for macOS threats. The multi-stage attack fingerprints the victim's system to deliver platform-specific payloads for macOS ARM64, macOS Intel, or Windows from attacker-controlled infrastructure. The second stage deploys Overlord RAT with extensive capabilities including keylogging, screen capture, audio and webcam access, filesystem manipulation, and remote desktop streaming. The malware communicates with command-and-control servers over encrypted WebSockets and maintains persistence through LaunchAgents. The campaign shares characteristics with previous North Korean operations, including similarities to FlexibleFerret malware and the Contagious Interview campaign.
