Talos Roundup Details Malware Threats and Indicators Observed Aug. 6–13

Summary
Talos summarizes malware observed Aug. 6–13, including Kuluoz, Razy, Remcos, Ursnif, Qakbot and others, with behaviors, sample-derived indicators of compromise and detection coverage.
Key points
- Kuluoz is delivered through shipment or travel-themed spam and can download additional malware; Razy steals and encrypts host data and may capture screenshots.
- Remcos provides remote access, command execution, keystroke logging and webcam or screenshot capture; it is commonly delivered in macro-enabled Office email attachments.
- Ursnif steals information and can download malware, while Swisyn disguises itself as system components and may drop further malware alongside rootkits.
- Qakbot targets banking and FTP credentials and can spread across networks via SMB; Zusy uses man-in-the-middle techniques to steal banking information.
- Tofsee turns infected systems into spam bots and can also conduct click fraud and cryptocurrency mining; DarkComet enables remote control, persistence and credential theft.
- The roundup includes sample-derived file hashes, registry artifacts, contacted IPs and domains, and MITRE ATT&CK technique visualizations; the listed IOCs are non-exhaustive and require contextual analysis.
Article Details
- Attack Vectors
- Kuluoz is often delivered through spam emails posing as shipment notifications or flight booking confirmations.
- Remcos is commonly delivered in macro-enabled Microsoft Office documents attached to malicious emails.
- Ursnif is commonly spread through malicious emails or exploit kits.
- Qakbot can spread across a network using SMB.
- Zusy injects itself into legitimate Windows processes and presents a deceptive form when a user accesses a banking website.
- A detection described in the article flags Microsoft Office processes starting Windows utilities, a behavior associated with malicious documents executing scripts.
- The article describes a DLL double-hijack attack chain beginning with a fraudulent software bundle.
- Defensive Notes
- Talos cautions that a single IOC does not necessarily indicate maliciousness and that IOC searching is only one part of threat hunting.
- Detection and protection coverage may be updated as additional threat or vulnerability analysis becomes available.
- The article reports AMP exploit-prevention detections for behaviors including process hollowing, suspicious Office-spawned utilities, long PowerShell commands, reverse TCP payloads, and specified malware or exploit activity.
