Impact & Mitigation

Impact Mitigation
  • The access could be used to gain initial access to the company’s infrastructure.
  • Commonly used passwords or weak passwords could lead to brute force attacks.
  • It would equip malicious actors with details required to launch sophisticated ransomware attacks, exfiltrate data, and maintain persistence.
  • This information can be aggregated to further be sold as leads/ document leaks on cybercrime forums, for financial gain.
  • Implement a strong password policy and enable MFA (multi-factor authentication) across logins.
  • Patch vulnerable and exploitable endpoints.
  • Do not store unencrypted secrets in .git repositories.
  • Do not share your secrets unencrypted in messaging systems like Slack or WhatsApp.
  • Monitor for anomalies in user accounts, which could indicate possible account takeovers.
  • Scan repositories to identify exposed credentials and secrets.
  • Monitor cybercrime forums for the latest tactics employed by threat actors.
