This rule detects the StealC infostealer malware by identifying specific byte patterns within the executable. These patterns correspond to functions for resolving Windows APIs, loading SQLite3 functions (often used by infostealers to extract data from browsers and other applications), and checking license expiration dates, which are characteristic of this particular malware family. The rule requires all three patterns to be present in a PE file (identified by the 'MZ' header) to trigger, reducing false positives.
