Daily Summary
Snake Keylogger activity dropped sharply on 2026-05-03, with only 5 new samples collected - a 45% decline compared to the 7-day average of 9. This marks the lowest single-day count in the current tracking window. The trend is clearly declining, suggesting either a temporary campaign pause or shifts in distribution infrastructure.
New Samples Detected
All five samples are script-based, with two .bat files and two .ps1 files, plus one .dll payload. This is notable because Snake Keylogger is typically delivered via Office macros or compiled executables. The shift to batch and PowerShell scripts indicates a possible move toward living-off-the-land techniques, potentially to evade static signature detection.
Distribution Methods
Based on the file types observed, distribution likely involves phishing emails containing zipped attachments, where the .bat or .ps1 file acts as a downloader or initial execution stub. The .dll file may be sideloaded via a legitimate process, a technique previously seen in Snake campaigns targeting logistics firms. No ISO or LNK files were detected today, suggesting a deviation from recent industry-wide trends.
Detection Rate
Current antivirus engines likely detect the older compiled Snake variants at high rates, but these script-based payloads - particularly when obfuscated - may evade heuristic scans. The .ps1 files could use reflection or base64 encoding to bypass AMSI, while .bat files masquerading as harmless scripts appeal to unsuspecting users.
C2 Infrastructure
No new C2 servers were recorded today, and no geographic patterns are available. This pause in infrastructure churn aligns with the reduced sample volume. However, the 5 new IOCs likely tie to existing known C2 endpoints, suggesting threat actors are reusing familiar channels rather than deploying fresh infrastructure.
7-Day Trend
After peaking mid-week (11 samples on 2026-04-30), Snake Keylogger activity has tapered off. Today’s numbers are the lowest in the tracking period. Unless samples resurge tomorrow, this marks a clear cooling phase.
Security Analysis
The transition to script-based payloads (.bat + .ps1) represents a strategic pivot from Snake Keylogger’s historic reliance on compiled .exe droppers. This change likely aims to defeat signature-based AV detection and lower victim suspicion - a .bat file appears less alarming than a binary. Defenders should monitor Execution/Command-Line events for anomalous PowerShell invocations (e.g., Base64 decoding or compressed commands) and enforce script execution policies to block unsigned scripts. Consider blocking attachment types .bat with Windows Defender attack surface reduction rules.
