UNG0801

Also known asung0801

UNG0801 (aka “Operation IconCat,” tracked by SEQRITE Labs as an Unknown Cluster) is a cyber-espionage/destructive activity cluster targeting Israeli organizations, particularly in the IT, HR, and software development sectors, observed beginning in the third week of November 2025. The cluster conducts Hebrew-language phishing and spear-phishing that mimics routine internal security communications (e.g., advisories/webinar announcements) and delivers booby-trapped Word/PDF lures. A core tradecraft element is masquerading malware as trusted antivirus software updates by spoofing vendor icons/branding—specifically Check Point and SentinelOne—to increase execution likelihood. SEQRITE describes two linked waves/campaigns with different end goals but shared playbook and timeframe: (1) a Check Point-branded delivery of a PyInstaller-packed Python wiper-like implant, PYTRIC, delivered via a malicious PDF (e.g., help.pdf) that directs victims to download a fake “Security Scanner” from Dropbox; PYTRIC can scan files, check admin privileges, and execute destructive actions such as wiping system data and deleting backups, and it communicates via a Telegram bot (“Backup2040”). (2) a SentinelOne-themed espionage wave delivering a Rust-based implant, RUSTRIC, via a macro-enabled Word document (e.g., Webinar.doc) sent in spear-phishing emails impersonating L.M. Group (a legitimate Israeli HR company); RUSTRIC enumerates 28 AV/EDR products, performs host/network reconnaissance (e.g., whoami/hostname/nslookup), and attempts HTTPS C2 over port 443. Infrastructure observations include use of Dropbox for payload retrieval, custom HTTPS C2, reused/low-cost VPS resources, and TLS certificate residue tying infrastructure to netvigil.org (with multiple active certificates observed via Censys). SEQRITE released detections (Trojan.50253.GC, Trojan.50254.GC, Trojan.50255.GC) and IOCs (including stratioai[.]org, 159[.]198[.]68[.]25). Attribution remains uncertain; SEQRITE assesses the activity likely originates from Western Asia and characterizes the actor as moderately sophisticated and persistent.

"Operation IconCat": Hackers Masquerade as Security Giants to Target Israeli Firms

Cyber-espionage/sabotage cluster targeting Israeli organizations by spoofing trusted antivirus vendor branding (notably SentinelOne and Check Point) to deliver malware via Hebrew-language phishing lures. Two linked waves: one deploying a destructive wiper (PYTRIC) and another deploying an espionage implant (RUSTRIC) for data theft; both share an AV-icon abuse playbook and overlapping infrastructure/signing-certificate artifacts (e.g., certificates tied to netvigil.org).

UNG0801: Tracking Threat Clusters obsessed with AV Icon Spoofing targeting Israel

UNG0801 is a threat activity cluster targeting Israeli organizations, primarily in the IT, HR, and technology sectors, using spear-phishing campaigns with malicious PDF and Word documents. The campaigns are characterized by the spoofing of antivirus vendor icons (Check Point and SentinelOne) to increase legitimacy. Two main malware implants are used: PYTRIC (a PyInstaller-packed Python wiper) and RUSTRIC (a Rust-based espionage tool). The group employs social engineering, AV icon spoofing, and custom malware for both destructive and espionage purposes.
