<p>Detection correlates file creation or modification of .lnk (shortcut) files in autostart locations with anomalous parent-child process lineage or unsigned binaries. Defenders should watch for LNK creation/modification events outside of known software installations, patch events, or OS updates. Flag shortcut targets pointing to suspicious locations or unknown binaries, particularly those written by script interpreters or spawned from phishing delivery chains.</p>

Log sources and channels

Exactly as MITRE states them in x_mitre_log_source_references. Where a channel is vague, it is vague in the source; kevmap does not tidy it.

Log sourceChannelData component
WinEventLog:SysmonEventCode=11DC0039 File Creation
WinEventLog:SysmonEventCode=2DC0061 File Modification
WinEventLog:SysmonEventCode=1DC0032 Process Creation

Mutable elements

Parameters MITRE marks as environment-specific. These are the knobs you are expected to tune; they are why an analytic is not a rule.

FieldDescription
TargetPathRegexTunable regex to flag suspicious shortcut target paths (e.g., temp folder, base64 in target, unusual executable names)
TimeWindowTime window used to correlate shortcut creation with process execution (e.g., 5-minute window)
UserContextScopeFilter for expected administrative installs versus end-user initiated shortcut creation
ZoneIdentifierThresholdConfigurable value to filter LNK files tagged with external source markers (e.g., ZoneId=3 for Internet)
