Analysed this Amadey payload. The binary acts as a dropper, installing itself in AppData\Local\Temp under a randomised name (e.g., Ujkjwrro.exe) and establishing persistence. Standard static string extraction (FLOSS) fails due to a custom modular arithmetic cypher used for configuration decryption. Dynamic memory extraction during the InternetConnectA API call reveals the C2 IP: 196.251.107.130 and URI: /h84jjfAr/index.php. A full technical write-up detailing the custom cypher bypass is be available on my Medium (https://medium.com/@svetli80/unmasking-amadey-when-static-analysis-fails-dynamic-extraction-prevails-0a201da0b6b8)
