According to Hudson Rock’s report shared with Hackread.com, the company traced every one of these breaches back to the same root cause: Jira credentials stolen by infostealer malware. These malware variants, including StealC, Raccoon, Redline, and Lumma Stealer, harvested login info from infected employee machines months (sometimes years) before the actual attacks.
You Should Know: How to Detect and Prevent Infostealer Attacks
Infostealers like Lumma, Redline, and Raccoon are designed to extract credentials, cookies, and sensitive data from infected systems. Below are key commands and steps to detect and mitigate such threats:
1. Detecting Infostealer Activity on Linux
Check for suspicious processes ps aux | grep -E 'stealc|raccoon|redline|lumma' Monitor network connections sudo netstat -tulnp | grep -i "unknown" Scan for malicious files sudo find / -name "stealc" -o -name "raccoon" -o -name "redline" -o -name "lumma" Check cron jobs for persistence crontab -l ls -la /etc/cron
2. Windows Detection & Removal
Check running processes
Get-Process | Where-Object {$_.ProcessName -match "stealc|raccoon|redline|lumma"}
Scan for registry persistence
reg query HKLM\Software\Microsoft\Windows\CurrentVersion\Run
Analyze network connections
netstat -ano | findstr ESTABLISHED
3. Securing Jira Credentials
- Enable Multi-Factor Authentication (MFA)
- Rotate credentials after suspected breaches
- Monitor Jira audit logs for unauthorized access
- Use endpoint detection (EDR) like CrowdStrike or SentinelOne
4. Preventing Future Infections
- Block known infostealer C2 servers via firewall:
sudo iptables -A INPUT -s <malicious_IP> -j DROP
- Regularly update anti-malware signatures
- Educate employees on phishing risks
What Undercode Say
Infostealers remain a critical threat due to their silent data exfiltration capabilities. Enterprises must adopt zero-trust policies, enforce strict credential hygiene, and deploy behavioral-based detection to counter advanced malware.
Expected Output:
- Suspicious process found: /tmp/.stealc - Unauthorized Jira login attempt detected - Blocked C2 IP: 185.143.223.11
