MIMICRAT: ClickFix Campaign Delivers Custom RAT via Compromised Legitimate Websites

Elastic Security Labs discovered a multi-stage ClickFix campaign that compromises legitimate websites to deliver a five-stage chain culminating in a custom native RAT called MIMICRAT. The attack uses an obfuscated PowerShell downloader with ETW and AMSI bypass, a Lua-based in-memory loader and Meterpreter-like shellcode, and a C++ implant with token impersonation and SOCKS5 tunneling. #MIMICRAT #ClickFix

Dark Web Profile: Lotus Blossom

Lotus Blossom is a long-running, China-attributed APT that evolved from spear-phishing and watering-hole campaigns into sophisticated supply-chain compromises and targeted espionage using custom implants like Elise, Sagerunex, Hannotog, and Chrysalis. The group’s Notepad++ update-channel compromise and prior attacks against diplomatic, military, and maritime infrastructure demonstrate a “low-and-slow” intelligence collection approach emphasizing DLL sideloading, living-off-the-land techniques, and clandestine persistence. #LotusBlossom #Chrysalis

QakBot Named a 2026 Top Malware Threat: An IoC Analysis

CloudSEK and follow-up research focused on QakBot as a top access trojan/loader that is commonly distributed via phishing, harvests credentials, maintains C2 access, delivers payloads, and moves laterally to enable targeted attacks and ransomware against email-reliant enterprises. The investigation analyzed Trellix IoCs (extracted 929 domains, filtered to 492, studied 125), 19 subdomains, multiple client and infrastructure IPs, and thousands of email-connected domains, identifying specific malicious artifacts (e.g., books[.]ttc[.]edu[.]sg -> 200[.]69[.]23[.]93) and providing a downloadable dataset for further hunting. #QakBot #Trellix

DomainTools Investigations | Lotus Blossom (G0030) and the Notepad++ Supply-Chain Espionage Campaign

Investigators determined the Notepad++ update mechanism (WinGUp/GUP.exe) was subverted for roughly six months to selectively deliver trojanized installers to a narrow set of high-value targets without modifying the project’s source code. The operation is attributed with moderate–high confidence to the China-aligned espionage cluster Lotus Blossom, which deployed bespoke implants (notably Chrysalis), DLL sideloading, and API-style HTTPS C2 to enable long-term intelligence collection. #LotusBlossom #Chrysalis

APT Profile – Fancy Bear – CYFIRMA

Fancy Bear (APT28) remains an active Russian state‑aligned espionage actor that quickly adopts newly disclosed vulnerabilities and uses spear‑phishing and credential harvesting to maintain long‑term access to government, defense, energy, and communications targets. The group recently weaponized a Microsoft Office vulnerability to compromise organizations in Eastern Europe and the EU, demonstrating a shift toward lightweight, high‑ROI tradecraft. #FancyBear #CVE-2026-21509
