Once delivery of the payload has occurred and the vulnerability has been exploited, the code uses BlackCap Grabber to perform actions on target and send the stolen information to a command and control server. These attacks obfuscate the code, and Python is mainly used to carry out the attacks. Usually, a supply chain would need to come from a third-party vendor or supplier with access to your infrastructure and not a website that hosts code that might be used in a company's environment. " It involves injecting malicious code into software or compromising hardware components to gain unauthorized access to a company's network or data," per Crowdstrike. GitHub notifies the appropriate service provider to respond accordingly-revoking the tokens and notifying the affected users-but we do not receive data on the number of validated tokens from partners.Apiiro and other cybersecurity firms are calling this a supply chain attack, and while that could technically be true, I think GitHub barely qualifies as a supply chain.Ī supply chain attack is a cyberattack targeting a trusted third-party vendor or supplier. * “Tokens for validation” represents the number of tokens we’ve sent to our token scanning partners for potential matches and thus may include false positives. Learn more about becoming a GitHub token scanning partner It’s as simple as a bit of paperwork, defining some regular expression to match your token format(s), and setting up an API endpoint. If you’re a cloud or API service provider using tokens for authentication and authorization and would like to protect your users from these rare, but potentially devastating scenarios, we’d love to work with you. Service providers-help us prevent security breaches before they happen Here’s an example of how one user was notified about a Discord token that was accidentally submitted to a public repository : When we detect a match, we’ll notify the appropriate service provider and they’ll respond accordingly-revoking the tokens and notifying the affected users. Within seconds of those commits being pushed (or private repositories being made public), we scan the contents for a number of known token formats. On a typical day, we see almost nine million commits pushed to GitHub. Now if you accidentally check in a token for products like Jira or Discord, the provider gets notified about a potential match within seconds of check-in, allowing them to revoke the token before it’s used maliciously. They’re in good company, joining other service providers including Alibaba Cloud, AWS, Azure, Google Cloud, Mailgun, npm, Slack, Stripe, and Twilio in protecting developers. Since adding token scanning, we’ve sent our integration partners one billion tokens for validation.* Five new token scanning partnersĪs part of GitHub’s commitment to protecting our customers from security threats, we’re happy to announce that we’ve partnered with Atlassian, Dropbox, Discord, Proctorio, and Pulumi to scan for their token formats. About a year ago, we introduced token scanning to help scan pushed commits and prevent fraudulent use of any credentials that are shared accidentally. If you’ve ever accidentally shared a token or credentials in a GitHub repository, or read about someone who has, you know how damaging it can be if a malicious user found and exploited it.
