Huntress reports that manufacturing accounted for about 17% of cyber attacks in 2025, up from 9% in 2024, citing its own cyber threat report. The article is a vendor trends piece rather than an incident report. It argues that ransomware operators now target production uptime and operational technology (OT), not just data, because manufact…
This weekly recap covers several concurrent incidents. ConnectWise disabled seven application identities and suspended Cloud Backup after unknown actors abused them to compromise Microsoft 365 tenants. China-nexus Armory Castle (UNC5221 / Warp Panda) exploited BeyondTrust Remote Support flaw CVE-2026-102764 (CVSS 9.3) as a zero-day in lat…
Check Point Research reports that commercial antidetect browsers, notably Kameleo, AdsPower and MultiLogin, are widely referenced on Russian-language underground forums and marketplaces.

Patchstack observed an attacker holding valid UpdraftCentral dashboard keys issuing signed commands to install backdoor plugins on connected …
A Huntress thought-leadership post sets out five priorities for security leaders in 2026: abuse of trusted IT tools, AI-enabled cybercrime, social engineering, multi-extortion ransomware and identity-based attacks including BEC. The article cites internal Huntress telemetry showing RMM abuse rising roughly 277% year over year, with Screen…
An attacker pushed forged commits to the default branches of two unrelated GitHub projects, hugo-paper and mevn-cli. The commits add a preinstall hook (scripts/preinstall.js) that downloads and silently runs a second-stage script from buildwithknexus.xyz during npm install or bun install. The commits copy the author, date and message of t…
In April 2026, Kaspersky GERT responded to an incident at a Middle East manufacturing organization where the actor gained domain admin-equivalent control of Active Directory. The actor created and linked a malicious GPO named PAYLOAD at the domain root. It pushed ransom notes, a wallpaper and lock screen, a logon banner and a local admini…
Unit 42 investigated a months-long intrusion against a European bank, which began with unauthorized VPN-based access through a third-party-managed external gateway appliance that did not enforce strict authentication. Using compromised credentials, the attacker ran noisy, high-volume internal reconnaissance and brute-force campaigns again…
Multiple ransomware groups, including Qilin and INC, are exploiting CVE-2026-0257, an authentication bypass in Palo Alto Networks PAN-OS GlobalProtect portals and gateways. Unit 42 has been investigating intrusions since early June across many sectors, including finance, healthcare and manufacturing. The flaw was patched on May 13 and ini…
Palo Alto Networks Unit 42 reports active exploitation of CVE-2026-0257, an authentication bypass in the portal and gateway components of PAN-OS GlobalProtect. The flaw lets unauthorized attackers circumvent security controls and open VPN connections. The October 19 update says Unit 42 continues to see exploitation attempts by ransomware …
On August 20, 2026, a compromised release of the Rust crate arrayref (0.3.10, about 245 million all-time downloads) appeared on crates.io. It added a dependency on the typosquatted crate proc-macro1 1.0.107, whose build script downloads and runs a remote binary at compile time. The maintainer account droundy appears to have been compromis…
Attackers took over more than 300 Tor exit relays in early October 2026 and changed their exit policies so SSH (TCP port 22) traffic was redirected to 12 attacker-controlled interception servers that harvested passwords and attempted to install the Ebury 1.8.3 backdoor. Researcher kaba found 333 redirecting exits (roughly 10% of about 3,0…
Mandiant and GTIG attribute exploitation of the critical BeyondTrust Remote Support zero-day CVE-2026-102764 to Armory Castle (formerly tracked as UNC5221), a likely Chinese government-backed espionage group. BeyondTrust dates the first known exploitation to Aug. 29 and says it detected and contained the activity Sept. 28. Only a small nu…
Palo Alto Networks Unit 42 reports that a suspected advanced actor tracked as CL-STA-0954 (aka UNC5820) deployed a previously unreported memory-resident ARM64 implant, PEERSTITCH, on Fortinet FortiGate firewalls. The group exploited the FortiOS path traversal flaw CVE-2025-61624 for the final stage. The intrusion hit a telecommunications …
Unit 42 analyzed the operational environment of a previously unreported, financially motivated, English-speaking actor using the handle BUGSTER. The actor ran the Hermes Agent framework with DeepSeek V4 as its reasoning engine and the Cursor IDE as a secondary tool, with safety controls disabled in both. With AI-generated scripts and reco…
On September 8, 2026, an attacker added a malicious source dependency to Deep-Live-Cam, a Python face-swapping app with about 96,600 GitHub stars. Commit 7895c547 ("chore: update requirements.txt") rewrote 18 dependency entries and added requests @ git+https://github.com/pypls/requests.git. This points installation to a lookalike reposito…
SOCRadar's Threat Research Unit (STRU) found open directories on 45.227.254.43 in late September 2026. They led to six more adversary servers tied to INC Ransom and The Gentlemen affiliates. The servers held 8,257 AI messages across 133 sessions, source code, stolen credentials, victim workspaces and 46 victim-specific INC encryptor build…
Unit 42 detailed a multi-stage intrusion in September 2024 against a telecommunications managed service provider, tracked as CL-STA-0954 (aka UNC5820). The attackers gained initial access by exploiting CVE-2024-47575 (FortiJump) on a central FortiManager and exfiltrated an archive with running configurations, credentials and private keys …
