This article discusses the Gold Melody Initial Access Broker, also known as Prophet Spider, which exploits leaked ASP.NET machine keys to infiltrate organizations across various industries in Europe and the U.S. The campaign employs sophisticated memory-resident techniques, bypassing traditional detection methods, and underscores the importance of securing cryptographic keys in ASP.NET applications. #GoldMelody #ProphetSpider #ASP.NETViewState
Keypoints
- The Gold Melody IAB leverages leaked ASP.NET machine keys to gain unauthorized access and sell it to other threat actors.
- The attackers use ViewState deserialization to execute malicious payloads directly in server memory, complicating detection.
- Exploitation primarily targets organizations in finance, manufacturing, high tech, and logistics industries in Europe and the U.S.
- The campaign involves deploying post-exploitation tools, including port scanners and privilege escalation programs.
- Organizations should prioritize securing ASP.NET cryptographic keys and monitoring behavioral IIS request patterns for detection.
