Internet Archive Breach Exposes 31 Million Users Through Two-Year-Old GitLab Token

The Internet Archive, one of the internet’s most critical digital libraries and home to the Wayback Machine, suffered a devastating security breach on October 9, 2024, exposing the personal data of approximately 31 million users. The incident, which combined a data breach with a simultaneous Distributed Denial of Service (DDoS) attack, highlights the cascading risks that organizations face when basic security hygiene is neglected over extended periods.

The Exploit Mechanics

The root cause of the breach was shockingly simple: an exposed GitLab authentication token that had been left vulnerable since late 2022. This single oversight gave attackers uninterrupted access to the Internet Archive’s source code repository for nearly two years. The threat actor exploited this token to gain unauthorized access to the organization’s authentication database, which contained records for approximately 31 million registered users.

The stolen data included email addresses, screen names, Bcrypt-hashed passwords, and password change timestamps. While Bcrypt hashing provides a meaningful layer of protection — it is computationally expensive to crack — the sheer volume of exposed records makes this breach particularly concerning, especially for users who reuse passwords across multiple platforms, including cryptocurrency exchanges and wallet services.

Simultaneously, a pro-Palestinian hacktivist group known as SN_BlackMeta launched a DDoS attack against the Archive’s infrastructure, overwhelming servers with traffic and temporarily taking the site offline. The data breach and the DDoS attack were conducted by separate groups, but their simultaneous execution compounded the damage and disrupted incident response efforts.

Affected Systems

The breach extended beyond the initial authentication database. The exposed GitLab token provided access to the Internet Archive’s source code, potentially allowing attackers to identify additional vulnerabilities or plant backdoors. Subsequent investigations revealed that the attackers later exploited unrotated Zendesk API tokens to access the Archive’s support ticket platform, where users had submitted personal identification documents.

For the cryptocurrency community, the breach carries particular significance. Many blockchain researchers, developers, and crypto enthusiasts maintain Internet Archive accounts for accessing historical blockchain data, archived whitepapers, and deprecated protocol documentation. The exposure of email addresses linked to these accounts creates potential vectors for targeted phishing attacks against individuals involved in the crypto space.

Bitcoin was trading at approximately $60,582 at the time of the breach, with Ethereum at $2,368, according to CoinMarketCap data. The crypto market was already under pressure from PlusToken-related ETH liquidations, and the broader cybersecurity concerns added to an atmosphere of heightened vigilance among digital asset holders.

The Mitigation Strategy

The Internet Archive’s founder, Brewster Kahle, acknowledged the breach and confirmed that the organization was working to secure its infrastructure. The mitigation process involved rotating all exposed authentication tokens, conducting a comprehensive audit of access controls, and rebuilding the authentication database with enhanced security measures.

For users, the immediate response should include changing passwords not only on the Internet Archive but on any platform where the same password was reused. Enabling two-factor authentication on all cryptocurrency-related accounts is critical, particularly exchange accounts and email addresses associated with wallet recovery phrases.

Security professionals recommend that organizations implement automated token rotation policies, ensuring that access tokens are refreshed at regular intervals regardless of perceived risk levels. The two-year window during which the GitLab token remained exposed represents a fundamental failure in basic security operations.

Lessons Learned

This breach serves as a stark reminder that some of the most damaging security incidents result not from sophisticated zero-day exploits but from basic operational oversights. A GitLab token left exposed for two years provided the entry point for a breach affecting 31 million users. The lesson is clear: security hygiene fundamentals — token rotation, access audits, and credential management — remain the most critical defenses against data breaches.

For the cryptocurrency community, the incident reinforces the importance of unique passwords for every service, hardware-based two-factor authentication, and vigilance against phishing attempts that may leverage breached email addresses. The intersection of general internet security breaches and cryptocurrency-specific threats means that a breach on any platform can cascade into crypto-related attacks.

User Action Required

If you held an Internet Archive account before October 9, 2024, take the following steps immediately: change your Internet Archive password, change the password on any account where you reused the same credentials, enable two-factor authentication on all financial and cryptocurrency accounts, monitor your email for phishing attempts referencing the breach, and consider using a hardware security key for your most sensitive accounts. The exposure of 31 million email addresses creates a long-tail risk that will persist for months or years as attackers leverage the data in targeted campaigns.
