Daily Summary
Snake Keylogger activity surged today with 9 new samples collected, marking a 91% increase over the 7-day average of 5. This sharp rise suggests renewed campaign activity, though no new C2 infrastructure was observed.
New Samples Detected
All 9 samples were PE32 executables (.exe), maintaining the family’s preference for packed executables. A single .bat file was also detected, which may serve as a loader or dropper in multi-stage infections. No shifts in naming conventions were evident; samples used generic filenames like “update.exe” and “setup.exe.”
Distribution Methods
Deliveries rely on phishing emails with weaponized attachments or links to fake software portals. The .bat file suggests recent campaigns may use script-based downloaders to bypass email security scanners, executing PowerShell commands to fetch the payload from remote servers.
Detection Rate
Current engine coverage remains moderate, with only 6 of 11 major AVs flagging the new .exe variants. The .bat sample showed lower detection (4/11), indicating script-based loaders may be evading static analysis. Heuristic scanning is recommended for improved detection.
C2 Infrastructure
No new C2 servers were identified today. Infrastructure appears static, with threat actors likely reusing previously observed IPs and domains. This may indicate a deliberate effort to avoid burning resources or a shift to cloud-based C2 using legitimate services.
7-Day Trend
Sample volume has remained below the week’s peak but is now climbing sharply after a brief lull on 2026-05-07. The current uptick suggests threat actors are resuming active campaigns after a short pause.
Security Analysis
The pairing of a .bat loader with Snake Keylogger executables mirrors tactics seen in 2024 campaigns, but the low detection rate for script-based variants is a fresh concern. Attackers are exploiting the gap between email security’s static signature-based detection and the dynamic download of the keylogger payload. SOC teams should deploy behavior-based monitoring for script execution originating from email attachments and block outbound connections to known keylogger C2 ranges.
