The source analyzes PebbleDash, described as a Lazarus/Hidden Cobra RAT, using sample MD5 d2de01858417fa3b580b3a95857847d5. Static and dynamic analysis found strings beginning with "Zip-bug," runtime loading of libraries including wsock32.dll, and use of IsProcessorFeaturePresent to identify the victim OS version before opening a socket connection. Decoding the sockaddr structure showed the malware connecting over port 443 to 112.217.108.138, an IOC the author notes also appears in a US-CERT advisory. The report gives defenders concrete pivots for PebbleDash detection, including API-resolution behavior, the C2 address, and related samples discovered through shared embedded strings.
