The security incidents at GitHub and Grafana are likely related to a large-scale "mini sandworm" supply chain attack

According to the threat intelligence released by Slow Fog, several high-frequency npm packages including AntV and Echarts-for-react, as well as the Python SDK durabletask, have recently been targeted by the Mini Shai-Hulud "mini sandworm" supply chain attack. The npm account atool was compromised, and the attacker automatically published 637 malicious versions within 22 minutes, affecting 317 packages. The attacker continuously uploaded durabletask versions 1.4.1, 1.4.2, and 1.4.3 within 35 minutes, bypassing normal release controls and impersonating an official Microsoft release.

The large-scale leak of GitHub tokens and the ransomware attack on Grafana Labs are likely related to this supply chain attack. Affected components include high-frequency components such as AntV and Echarts-for-react in the npm ecosystem, as well as Python packages durabletask 1.4.1, 1.4.2, and 1.4.3. Attackers can steal cloud and local credentials, gain unauthorized access to internal repositories and sensitive cloud infrastructure, move laterally to developer machines and CI/CD pipelines, sell and exploit leaked GitHub tokens, and implement extortion and data leak threats.

Slow Fog recommends immediately rotating all exposed credentials, replacing affected packages, isolating potentially infected systems, and implementing strict dependency review policies. Previously, it was reported that the "mini sandworm" worm has recently completed widespread infection in open-source code repositories, and developers should be vigilant in checking for issues.
