Check Point researchers report large-scale phishing campaigns that abuse fake calendar invitations to harvest Microsoft account credentials. Lures arrive either as a malicious .ics attachment or as a link, for example in a fake Microsoft Teams meeting invite, that appears to point to one destination but leads to a credential-harvesting pa…
In September 2026, researchers reported an attack that began inside a live AI coding assistant session at a software company. The attacker gained control of a developer's session, and the assistant recommended a PyPI package that looked normal. The developer installed it, and a hidden infostealer took source code, repository secrets and h…
FortiGuard Labs describes a large-scale, global campaign that uses heavily obfuscated JScript droppers to launch an AutoIt/Lua-based loader with low detection rates. The loader delivers several popular RATs and infostealers, including a version of Snake Keylogger. The infection chain relies on business email compromise tactics, impersonat…
Silent Lynx, tracked as UAT-6275 by Cisco Talos and TAG-193 by Recorded Future Insikt Group, has been linked to a new set of attacks on government organizations across the Commonwealth of Independent States. The activity ran from June 2025 through August 2026 and used four infection chains to deploy custom reverse shells (FoalShell, Chvos…
ESET documented the evolution of MATCHBOIL, a custom C downloader used by the Russia-aligned cyberespionage group UAC-0099. Samples span April 2024 to April 2026, although CERT-UA first documented the malware in August 2025. Each iteration became more sophisticated, with new obfuscation, sandbox checks and persistence methods. All victims…
Symantec reports that the Russia-linked APT28 (aka BlueDelta, Fancy Bear, Forest Blizzard), tracked by Symantec as Swallowtail, targeted entities in two NATO member states. Victims include a law enforcement agency, a naval shipbuilder and a manufacturer of military aircraft engines. In the shipbuilder intrusion in late July 2026, operator…
Kaspersky identified MovieReaper, a previously unknown modular, multi-stage crimeware framework distributed since mid-August 2026 through movie-themed torrents, including fake "The Odyssey (2026)" releases. Rather than compromising individual trackers, the actor modified the public torrent file repository itorrents.org, so trackers relyin…
SafeDep flagged the malicious npm package ulid-xyz in June 2026. It typosquats ulidx and is a cross-platform remote access trojan. It is delivered through a three-layer transitive dependency chain: ioredis-xyz (a clone of the legitimate ioredis client) depends on redis-type-xyz (an empty manifest posing as Redis OM), which in version 1.10…
Unit 42 attributes with high confidence to an Iranian state-aligned actor, tracked as CL-STA-1178, a campaign called Blinder Tunnel. In March 2026 it targeted an individual in Iraq's critical infrastructure sector, after infrastructure staging that began as early as November 2025. The actor impersonated the Dubai Airports IT department an…
Darktrace researchers documented a new campaign distributing CikaBika Bot, a Rust-based remote access trojan controlled entirely through Discord. The infection chain starts with a disk image named PropositionProjet.img, which contains a French-language decoy PDF and a Windows shortcut disguised as a Word document. A Nim loader extracts th…
Kaspersky researchers report that the APT group Mirage Kitten has moved from native C/C++/Go malware to Node.js and JavaScript implants, NodeRabbit and PollCat. Both are cross-platform RATs delivered through spear-phishing by fake recruiters on LinkedIn and other job platforms, using trojanized coding-challenge archives hosted on Amazon S…
Kaspersky analysis of an installer first classified as adware (MD5 c24e99f9437feacaa63766a3cde3fe3d) found that it delivers the ValleyRAT backdoor. The installer drops a modified, signed Chinese wallpaper tool, QN Wallpaper, and uses it for DLL sideloading of a malicious libcef.dll. The adware's advertising function does not work. Attacke…
Qilin and Settra ransomware groups are actively exploiting CVE-2026-0257, an authentication bypass in PAN-OS GlobalProtect and Prisma Access disclosed in May 2026, according to ReliaQuest. Because access arrives through the victim's own VPN, it can resemble legitimate remote work and go unnoticed until credential theft, lateral movement, …
Researchers at SafeDep analyzed a macOS implant recovered from a compromised workstation. Infection began on 2026-07-26 with a paid YouTube video ad impersonating TradingView that led to a fake .pkg installer. The malware is a remote-controlled task runner, not a single-purpose stealer. It persists via a LaunchAgent that re-fetches a shel…
SentinelOne reports observing APT29 (Midnight Blizzard / Cozy Bear, Russia's SVR) running the CaptiveCrunch campaign, disclosed by Microsoft in July 2026, across multiple customer environments in three regions. The operation abuses captive-portal behaviour and forged name resolution to push fake browser updater downloads to roaming Window…
Elastic Security Labs is tracking REF8801, a campaign in which a fake Web3 venture capital accelerator, Apex Accelerator (Apex Foundation), targets cryptocurrency startups and founders with malicious npm packages. The packages, @apexacc/cli and @apexacc/audit, pose as an AI advisor and an MCP-based security scanner, with offers of free Cl…
Kaspersky researchers describe a new MacSync macOS infostealer variant, first seen in the wild in September 2026, that replaces the earlier AppleScript-based droppers with FAT Mach-O binaries written in Objective-C and Swift. MacSync is sold as malware-as-a-service, so delivery varies by operator. In this campaign it spread through malici…
