Over 41,000 US Department of Homeland Security (DHS) employee records, including undercover ICE agents, were leaked online by a hacktivist group, exposing names, offices, contact details, and assignments. The data was reportedly stolen from an Okta single sign-on system earlier in 2026 and published by DDoSecrets ^[28]^[43]^[66]^[72].
The Belgian Federal Public Service Finance temporarily suspended tax services following a cyberattack, which occurred just before a filing deadline ^[45].

Major Incidents or Breaches

GitHub confirmed a breach involving the exfiltration of over 3,800 internal repositories. The breach was traced to a compromised employee device, which had installed a malicious version of the Nx Console Visual Studio Code extension. This extension was compromised during the recent TanStack npm supply-chain attack. The threat actor TeamPCP has claimed responsibility. The breach also impacted other organisations, such as Grafana, which failed to rotate a GitHub workflow token after the TanStack incident, leading to further compromise^[4]^[10]^[13]^[16]^[21].
Microsoft disrupted a malware-signing-as-a-service operation, known as Fox Tempest, which weaponised Microsoft’s Artifact Signing system to deliver malicious code and facilitate ransomware campaigns. The service enabled threat actors to sign malware with fraudulent Microsoft-issued certificates to evade security controls^[7]^[42].
