Daily Summary
Snake Keylogger activity rose to 6 new samples on 2026-10-11, up 83% from the 7-day average of 3. This is the highest single-day count in the observed window and the second consecutive day above baseline, indicating a sustained rather than incidental increase. One new C2 server and 7 new IOCs were identified alongside the sample set.
New Samples Detected
The 6 samples split into 4 Windows executables (.exe) and 2 batch files (.bat). The presence of .bat droppers alongside compiled binaries is the more interesting detail: batch scripts are commonly used as lightweight loaders that pull the main payload from a remote host, which lets operators rotate the final executable without re-delivering the dropper. This dual-format pattern suggests a staged infection chain rather than standalone binaries, and it aligns with Snake Keylogger’s established behavior of using a loader to fetch and execute its core module. No naming convention shift was observed across the samples, but the mix of formats is worth tracking for repeat delivery infrastructure.
C2 Infrastructure
One new C2 server was added to the tracked set today, bringing fresh exfiltration and tasking endpoints into play. Combined with 7 new IOCs, this points to active infrastructure rotation rather than reuse of stale endpoints. Rotation at this cadence is typically a response to takedowns or blocklist ingestion, and it means static domain blocklists alone will likely miss upcoming beacons. Analysts should treat today’s IOC set as short-lived and expect the server to be replaced within days.
7-Day Trend
At 6 samples versus a 7-day average of 3, today sits 83% above baseline, well past the 25% threshold that flags a deviation. The two-day run above average is the key signal: a single spike can be noise from a one-off campaign, but consecutive elevated days suggest an active distribution push. If tomorrow holds above 4, this should be reclassified as a sustained surge rather than a short bump.
IOC Highlights
The 7 new IOCs cover the new C2 server and supporting endpoints tied to today’s samples. With C2 rotation this frequent, the highest-value IOCs are the network indicators, not file hashes, since the payload changes faster than the delivery infrastructure. Feed the C2 domain and any associated IPs into DNS and proxy blocklists immediately, and prioritize retro-hunting historical logs for the past 7 days against the new server.
Security Analysis
The .bat-plus-.exe split echoes a delivery pattern seen in commodity Snake Keylogger campaigns where cheap script loaders front a rotating executable, keeping the expensive-to-rebuild payload out of initial email attachments. The non-obvious risk is that defenders scanning only .exe attachments will miss the batch droppers entirely, letting the loader execute and pull the real payload post-delivery. The actionable recommendation: enable and enforce script-blocking or constrained language mode for .bat and .cmd execution on endpoints, or at minimum alert on batch scripts spawning network or PowerShell activity, since that parent-child relationship is far rarer in legitimate workflows than a standalone executable and gives SOC teams a high-signal detection point against staged Snake Keylogger delivery.
