On May 20, 2026, GitHub reported unauthorized access to its internal repositories, affecting 3,800 repositories. Binance co-founder Changpeng Zhao (CZ) urged developers to double-check and change their API keys, emphasizing that even private repositories are at risk. The breach was linked to a compromised employee device due to a malicious VS Code extension. GitHub confirmed that it has contained the breach and is monitoring for further activity, stating no evidence of impact on customer information outside its internal systems.

This incident follows a rise in crypto hacks, with significant financial losses reported in recent months.
