Organizations often underestimate the risks posed by cookies on corporate devices, especially with the surge in infostealer malware. Research by Aurelija SkebaitÄ and NordVPN, “Sticky fingers in the cookie jar: Research reveals the risks of web cookies” (Read Here), highlights critical findings:
- Types of Cookies: First-party, third-party, super cookies, and zombie cookies.
- 93.7 billion cookies were sold on dark web forums and Telegram.
- 85% of CryptBot-stolen cookies remained active.
- Top sources: Google and Microsoft.
- Top affected countries: Brazil, India, Indonesia, US, Vietnam, Philippines, Turkey, Pakistan, Egypt, and Thailand.
You Should Know: How to Detect and Mitigate Cookie Theft
1. Identifying Infostealer Activity
Use these commands to detect suspicious processes:
Linux (Check Running Processes)
ps aux | grep -E 'redline|lumma|vidar|cryptbot'
Windows (PowerShell – Check Network Connections)
Get-NetTCPConnection | Where-Object {$_.State -eq "Established"} | Select-Object LocalAddress, RemoteAddress, OwningProcess
2. Analyzing Stolen Cookies
Extract and inspect browser cookies for anomalies:
Linux (Chrome Cookies Path)
sqlite3 ~/.config/google-chrome/Default/Cookies "SELECT FROM cookies;"
Windows (Export Chrome Cookies via PowerShell)
Copy-Item "$env:USERPROFILE\AppData\Local\Google\Chrome\User Data\Default\Cookies" -Destination "C:\temp\cookies_backup"
3. Blocking Malicious Cookies
Browser Hardening (Chrome/Firefox)
Disable third-party cookies:
- Chrome: `chrome://settings/cookies` ā Block third-party cookies
- Firefox: `about:preferencesprivacy` ā Strict mode
Linux (Hosts File Blocking)
echo "0.0.0.0 tracking.malicious.com" | sudo tee -a /etc/hosts
4. Monitoring Dark Web Exposure
Use Have I Been Pwned (HIBP) or DeHashed to check leaked credentials.
What Undercode Say
Cookie theft is a silent threatāattackers exploit session persistence for lateral movement. Key takeaways:
– Rotate credentials after suspected breaches.
– Enforce MFA to reduce cookie-based session hijacking.
– Monitor dark web for stolen corporate credentials.
– Use endpoint detection (EDR/XDR) for infostealer activity.
Expected Output:
[+] No active infostealer processes detected. [+] Third-party cookies blocked in Chrome. [+] Dark web scan completeāno exposed credentials found.
Prediction
As infostealers evolve, expect AI-driven cookie hijackingāautomated tools will bypass MFA by cloning behavioral biometrics. Enterprises must adopt zero-trust cookie policies to mitigate future attacks.
