🚨 Update Your Detection Rules: New In-Memory Loader
We caught a highly evasive #HanGhost loader, designed to bypass traditional detection through layered obfuscation and in-memory execution. This activity targets corporate users handling payments, logistics, and contract workflows, expanding exposure across critical operations.
⚠️ The delivery chain combines obfuscated JavaScript, hidden PowerShell execution, and environment-variable staging.
In the second stage, the loader retrieves an image file and extracts an encrypted payload embedded at the end of the file, combining steganography with in-memory loading and making detection significantly harder ❗️
👾 The loader is used to deliver multiple malware families: #PureHVNC, #XWorm, #Meduza, #AgentTesla, and #Phantom, with some chains also deploying #UltraVNC, extending the impact from initial access to persistent remote control.
⚡️#ANYRUN Sandbox allows analysts to reconstruct the full execution chain, helping confirm complex multi-stage activity earlier and reduce MTTR.
🔗 JavaScript-to-Payload execution chain:
JS ➡️ PowerShell ➡️ in-memory .NET assembly ➡️ PNG payload ➡️ Malware
📈 The campaign shows wave-based activity, indicating ongoing development and scaling:
March 26 — early cluster
April 1–2 — first large multi-family wave
April 3 — focused wave (PureHVNC / AgentTesla / Phantom)
April 6 — PureHVNC-heavy activity
April 7 — new peak with split between PureHVNC and XWorm/Meduza clusters
April 8 — multi-family wave (PureHVNC / Phantom / AgentTesla)
April 9–13 — more focused wave dominated by PureHVNC, with Phantom, DarkCloud, Formbook, and Meduza also present
