A recent conversation between Oracle’s hacker, known as “rose87168,” and an Oracle representative was leaked, revealing intriguing details. The hacker, Rose, demonstrated access to a ‘dmh-global.com’ employee’s account (timestamp 00:15), raising questions about whether Rose successfully decrypted passwords from Oracle’s database. This aligns with the initial victim company list Rose provided.
You Should Know: Investigating Database Breaches & Password Decryption
If you suspect a database breach, follow these steps to analyze and secure compromised credentials:
1. Check for Exposed Credentials
Use Have I Been Pwned (HIBP) to verify leaked emails/passwords:
curl -s "https://api.pwnedpasswords.com/range/$(echo -n 'YourPassword123' | sha1sum | cut -d' ' -f1 | head -c 5)" | grep -i $(echo -n 'YourPassword123' | sha1sum | cut -d' ' -f1 | tail -c 36)
2. Analyze Database Dumps
If you obtain a leaked database, inspect its structure:
file leaked_database.db Check file type strings leaked_database.db | grep -i "admin" Search for admin accounts
3. Crack Hashed Passwords
Use John the Ripper or Hashcat to test password strength:
john --format=raw-md5 hashes.txt MD5 cracking hashcat -m 1000 -a 0 hashes.txt rockyou.txt NTLM brute-force
4. Secure Oracle Database Access
If managing Oracle databases, enforce strong passwords and monitor logs:
ALTER USER sys IDENTIFIED BY "NewStrongP@ssw0rd!"; Change default passwords SELECT username, account_status FROM dba_users; Check active accounts
5. Enable Multi-Factor Authentication (MFA)
Prevent unauthorized access via MFA:
google-authenticator Linux MFA setup
What Undercode Say
Database breaches remain a critical threat, especially when weak encryption or exposed credentials are involved. Always:
– Audit database permissions
– Use strong, unique passwords
– Monitor unauthorized access attempts
– Implement MFA and encryption
Expected Output:
[+] Password 'YourPassword123' found in 3 breaches. [+] Admin accounts detected in database dump. [+] Hashcat cracked 5/10 passwords in 2 minutes.
