By /

Featured Image
The latest report from ANY.RUN highlights Lumma Stealer as the top malware threat, reaffirming its dangerous dominance in cybercrime. Known for its stealthy data exfiltration capabilities, Lumma remains a critical risk, followed closely by Xworm and Snake—two notorious Remote Access Trojans (RATs). The report also emphasizes the rise of loaders, malicious tools used to deploy additional payloads.

You Should Know: Analyzing and Defending Against Lumma Stealer

1. Understanding Lumma Stealer

Lumma is an info-stealer targeting:

  • Browser cookies, passwords, and autofill data
  • Cryptocurrency wallets (MetaMask, Exodus, etc.)
  • FTP and SSH credentials
  • Screenshots and clipboard data

2. Detection & Analysis (ANY.RUN Sandbox)

Use ANY.RUN to analyze Lumma samples:

 Download a sample (use a secure VM) 
wget --user=ANY.RUN_USER --password='YOUR_PASS' https://malware.sample/lumma.exe

Run in ANY.RUN sandbox for behavior analysis 
anyrun-upload lumma.exe --interactive

3. Mitigation Steps (Windows/Linux)

Windows Defender Exclusion Check:

 List exclusions (common evasion tactic) 
Get-MpPreference | Select-Object -ExpandProperty ExclusionPath

Linux Memory Analysis (Volatility):

vol.py -f lumma_dump.mem --profile=Win10x64 malfind

4. YARA Rule for Detection

rule Lumma_Stealer { 
meta: 
description = "Detects Lumma Stealer variants" 
strings: 
$s1 = "LummaC2" wide 
$s2 = "steal_browser" 
condition: 
any of them 
}

5. Network IOCs (Indicators of Compromise)

  • IPs: 185.56.83.19, `91.201.72.122`
  • Domains: lumma-c2[.]top, `stealer-api[.]xyz`

What Undercode Say

Lumma’s persistence highlights the need for:

  • Enhanced EDR rules focusing on credential dumping.
  • Memory scanning for hidden payloads.
  • User training against phishing (common delivery method).

Relevant Commands:

 Check for suspicious processes (Linux) 
ps aux | grep -E 'stealer|payload'

Windows forensic artifact collection 
autoruns.exe -accepteula -a  -ct > autoruns_log.txt

Prediction

Lumma will likely evolve with AI-driven obfuscation, while RATs like Xworm adopt zero-day exploits for initial access.

Expected Output:

  • Lumma Stealer Tops ANY.RUN’s Latest Malware Threat Report
  • Key URLs: ANY.RUN Report
  • Commands: YARA, Volatility, Windows Defender checks
  • IOCs: IPs, domains, detection rules
