Cybersecurity Brief – 2026-05-21

Thu, 21 May 2026 00:00:00 +0000

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].
Hackers bypassed multi-factor authentication on SonicWall Gen6 SSL-VPN appliances due to incomplete patching, brute-forcing VPN credentials and deploying tools used in ransomware attacks^[15].
The Ukrainian cyberpolice, in cooperation with US authorities, identified an infostealer operator responsible for compromising 28,000 accounts via malware targeting an online service^[14].
Grafana suffered a data breach stemming from a missed token rotation following the TanStack npm supply-chain attack, underscoring the ongoing risks in the software supply chain^[16].
