Vulnerability: Insecure Credential Storage
Family: PoisonIvy
Type: PE32
MD5: b0748f1c1a17bad44dc9bd750fc97547
SHA256: 060c15f401ce4d38d70e7f60aabe31c81935d2c261e350c0ea34387886d48920
Vuln ID: MVID-2024-0688
Dropped files: PILib.dll, Poison Ivy.ini, .pip
Disclosure: 09/03/2024
Description: PoisonIvy listens on TCP port 3460 by default but that can be changed. When generating PoisonIvy PE files, credentials are stored in cleartext if not using the PasswordKey=1 option which gets stored in ".pik" files. The "Ivy.ini" configuration and profile ".pip" files also contain credentials in cleartext.
