Daily Summary
Today’s 6 new Snake Keylogger samples represent a 30% decline relative to the 7-day average of 9, continuing a cooling trend. No new C2 infrastructure was observed, and sample volume is the lowest in the past week. This drop may indicate a shift in operator activity or a temporary operational pause.
New Samples Detected
Script-based payloads dominate today, with two .bat and two .ps1 files accounting for two-thirds of all samples. Only one .exe and one .dll were captured, marking a departure from the usual executable-heavy mix seen in prior days. Naming patterns remain varied with no clear campaign branding, though several .ps1 files use obfuscated variable names consistent with known Snake loader techniques.
Distribution Methods
The heavy script presence (.bat and .ps1) suggests delivery via phishing attachments or downloader chains that bypass initial execution restrictions. The absence of macro-enabled documents or ISO files today may reflect increased detection of those formats, pushing operators toward script-based initial stages. No new C2 infrastructure implies the existing pool is sufficient for current operations.
Detection Rate
Public AV detection across today’s samples is moderate, with script-based files showing slightly lower detection rates than the .exe variant. The .dll sample is being flagged by fewer engines, potentially indicating a fresh or lightly-signed build. Operators appear to be rotating signatures to maintain a small evasion window.
C2 Infrastructure
No new C2 domains or IPs were recorded today. All observed communications resolve to previously documented addresses, with no geographic shift in hosting. This stability suggests operators are not actively expanding infrastructure, aligning with the lower sample count.
7-Day Trend
Sample volume has declined over the last three days after a mid-week peak of 14 on May 2. Today’s 6 samples mark the lowest single-day count in the past seven days, confirming a downward trend.
Security Analysis
A non-obvious observation is the intentional absence of .vbs files today - a format Snake Keylogger used heavily in March campaigns. This may signal a deliberate evasion of behavioral analytics tuned for VBS-based droppers. Defenders should ensure Script Block Logging and PowerShell transcription are enabled, and tune SIEM rules to flag anomalous .bat and .ps1 execution from email or web download directories.
