GitHub announced it has reset the passwords of a number of accounts after the company noticed unauthorized access. The hackers used credentials leaked online after the numerous data breaches suffered by other companies.
Users’ bad habits in password management are a key component for the success of this kind of attacks. Users often chose weak passwords and share the same credentials across multiple websites.
GitHub confirmed to have detected a large number of attempts to access users’ accounts. The unauthorized accesses were detected on Tuesday evening as explained in the official announcement. GitHub highlighted that its systems have not been hacked by attackers.
“On Tuesday evening PST, we became aware of unauthorized attempts to access a large number of GitHub.com accounts. This appears to be the result of an attacker using lists of email addresses and passwords from other online services that have been compromised in the past, and trying them on GitHub accounts. We immediately began investigating, and found that the attacker had been able to log in to a number of GitHub accounts. GitHub has not been hacked or compromised.” states the security update published by GitHub.
“For affected accounts, usernames and passwords are involved. Additionally, for some accounts, other personal information including listings of accessible repositories and organizations may have been exposed,”
GitHub has already reset the passwords of the affected accounts, at the same time it is suggesting users to adopt a proper security posture to avoid being victims of the hackers.
“We encourage all users to practice good password hygiene and enable two-factor authentication to protect your account,” states GitHub. “These attacks often evolve, and we’re continuing to investigate and monitor for new attack vectors.”
Recently a number of web services suffered a data breach, the criminal underground was flooded with hundred thousand million records resulting from the security breaches of LinkedIn , Myspace, VerticalScope, Tumblr, and VK .
