A recent security incident on GitHub involved the compromise of user accounts with weak passwords through a brute force attack using nearly 40,000 unique IP addresses. In response, GitHub reset passwords, revoked personal access tokens, OAuth authorizations, and SSH keys for affected users, urging them to create stronger passwords and review their accounts for suspicious activity. The platform is taking further steps, such as implementing additional rate-limiting measures and banning the use of commonly-used weak passwords for logging in. Users with strong passwords or two-factor authentication may have also observed failed login attempts, highlighting the importance of maintaining robust account security. GitHub emphasizes the necessity of strong passwords and two-factor authentication while continuing to investigate the incident and monitor for unauthorized activity.
