Provenance Record

Well-structured News piece (590 words, within the 400-1200 News range). Clear Overview / What We Know / What We Don't Know / Analysis flow. Technical detail is precise without sensationalism, and the 'What We Don't Know' section honestly bounds the reporting (no named victims, no compromise count, in-memory self-deletion limits forensic reconstruction, attribution stops at the KongTuke/Woodgnat tracking handles).

Read all 4 gzipped snapshots from disk and verified every cited specific. source-0 (Symantec/security.com, 200): confirms Backdoor.Mistic, in-memory/no-file-to-disk/kill-switch self-deletion, deployed since April 2026, Zscaler/MLTBackdoor prior naming, KongTuke=Woodgnat IAB, MpExtMs.exe side-load + EndpointDlp.dll loader, sectors insurance/education/IT/professional services, ModeloRAT observed in attacks deploying Qilin. source-1 (Help Net Security, 200): confirms KongTuke/Woodgnat active since at least May 2024, the full capability list (upload/download/move/rename/delete files, create folders, modify check-in frequency, execute code in memory, terminate/remove itself), in-memory stealth enabling long-term access, ModeloRAT as a Python-based RAT developed by Woodgnat. source-2 (SecurityWeek, 200): confirms the six ransomware families (Qilin, Interlock, Rhysida, Akira, 8Base, Black Basta), April 2026 deployment start, LOLBins (Curl, Reg.exe, Net/net.exe, PowerShell, Certutil, WMIC), and ClickFix/FileFix/CrashFix techniques paired with helpdesk/IT-support lures via Microsoft Teams since April 2026. source-3 (Security Affairs, 200): confirms the in-memory/no-file/kill-switch description and the MpExtMs.exe + EndpointDlp.dll DLL-sideloading chain. The Hacker News (which returned 403 and would have been unverifiable) is NOT cited. All snapshots returned HTTP 200; none required Archive.org fallback or live WebFetch.

Every technical specific traces to a cited source carrying it, with Symantec correctly used as the primary for the malware/sideloading detail. The headline's 'Six Ransomware Crews' matches SecurityWeek's exact six-family enumeration. KongTuke=public handle / Woodgnat=Symantec's handle attribution is correct and consistent across the body. ModeloRAT is correctly attributed as Woodgnat's own Python RAT tied to Qilin deployments. No hallucinated facts, dates, or names detected.

High-quality, accurate, fully-sourced cybersecurity report. The only automated finding is a non-blocking allowlist warning for Symantec's own domain. APPROVE.
