The emerging Arkana Ransomware Group has claimed responsibility for a massive breach of WideOpenWest (WOW!), one of the largest Internet Service Providers (ISPs) in the United States. The attack traces back to an Infostealer infection from September 2024, where credentials from the following domains were compromised:
- wowinc.symphonica.com
- wowway.com (visible at 0:12 in the group’s music video)
- appiancloud.com (visible at 0:15)
These credentials were found on an infected employee’s computer, highlighting how initial access via Infostealers can lead to large-scale ransomware attacks.

You Should Know: Detecting & Preventing Infostealer Infections
Infostealers are malware designed to harvest credentials, cookies, and sensitive data from infected machines. Below are key commands, tools, and steps to detect and mitigate such threats:
1. Detecting Infostealer Activity on Windows
- Check for unusual processes in Task Manager:
Get-Process | Where-Object { $<em>.CPU -gt 50 -or $</em>.WorkingSet -gt 500MB } | Format-Table -AutoSize - Scan for persistence mechanisms:
reg query HKCU\Software\Microsoft\Windows\CurrentVersion\Run reg query HKLM\Software\Microsoft\Windows\CurrentVersion\Run
- Analyze network connections:
netstat -ano | findstr ESTABLISHED
2. Linux-Based Detection (Sysmon/Osquery Alternative)
- Check for suspicious cron jobs:
crontab -l ls -la /etc/cron.*
- Monitor active connections:
ss -tulnp | grep ESTAB
- Hunt for hidden processes:
ps aux | grep -E "(curl|wget|nc|ncat|socat|sh -i)"
3. Mitigation Steps
- Reset all credentials exposed in logs (use a password manager).
- Enable MFA on all critical accounts.
- Deploy EDR/XDR solutions (CrowdStrike, SentinelOne) for real-time monitoring.
- Isolate infected machines and conduct forensic analysis using Volatility (Linux/Win):
volatility -f memory.dump --profile=Win10x64_19041 pslist
What Undercode Say
Infostealers remain a critical initial attack vector for ransomware groups. Organizations must:
– Regularly audit credential exposure in stealer logs (via services like Have I Been Pwned).
– Implement strict endpoint security policies (application whitelisting, least privilege).
– Train employees on phishing and malware risks.
Expected Output:
- A detailed forensic report of infected systems.
- Compromised credentials revoked and replaced.
- EDR alerts configured for abnormal data exfiltration.
