Title
Description
What do Ruby’s rest-client, Python’s ctx, and npm’s ua-parser-js have in common? They all suffered account takeovers that were preventable. Attackers aim to take control of a legitimate RubyGems.org user account and then use it to upload malicious code. It might dial home. It might steal your keys. Perhaps it will encrypt your disk. Or all of the above! Don’t you wish it couldn’t happen? MFA prevents 99.9% of account takeover attacks. Come learn about MFA, the history of RubyGems.org MFA support, the new MFA policy for top gems, and what’s on the horizon.

The video titled "RubyGems.org MFA: The Past, Present and Future," presented by Jenny Shen at RubyConf Mini 2022, focuses on the significance of Multi-Factor Authentication (MFA) for RubyGems.org to prevent account takeovers and enhance security in the software supply chain. ### Key Points Discussed: - **Introduction to MFA**: MFA prevents 99.9% of account takeover attacks, which can result in malicious code uploads that compromise software through hacks like data exfiltration and encryption. - **The Need for MFA in RubyGems**: There has been an alarming rise in supply chain attacks, with a notable 742% increase reported over the past three years. Such attacks often occur through account takeovers and typo-squatting. - **Real-life Examples**: Shen references cases like the 'rest-client' gem and 'strong-password' gem, highlighting how attackers gained access and published malicious code through compromised accounts. - **Comparison with Iodine Deficiency**: Shen draws parallels between preventing goiter, a condition due to iodine deficiency, and the need for proactive measures against account takeovers. Just as iodizing salt helped alleviate goiter cases, implementing MFA can protect against modern cybersecurity threats. - **Current State and Implementation of MFA**: The current MFA mechanisms include time-based one-time passcodes (TOTP) that have different levels based on user roles. Future policies are presented to ensure that top gem maintainers are mandated to enforce MFA effectively. - **Community Involvement in Policy Creation**: Shen discusses the collaborative process, involving community feedback through requests for comments (RFCs) and establishing key metrics for which users should be prioritized to enable MFA based on download counts. - **Future Directions**: The ongoing strategy aims to simplify MFA activation and include additional support such as biometric devices. Ruby Central's partnership with Shopify is also highlighted as a significant step in funding security initiatives for RubyGems. ### Conclusions and Takeaways: - The importance of MFA is emphasized for all users of RubyGems, with calls for gem maintainers to secure their accounts. The prevention of future incidents via proactive policies is vital. - The talk closes with a reminder to enable MFA across all accounts, regardless of gem popularity, illustrating the broader principle of security diligence.
