Malicious code in gocommunity.io/orderedbtree (Go)

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Part of the Graphalgo campaign. The module, first published around 2026-08-11, contains a second-stage remote access trojan in plaintext that runs automatically. The RAT collects system information, executes decrypted Go or JavaScript payloads, and polls two command-and-control channels every 3-10 seconds: an Ethereum smart contract used as a dead drop (Arbitrum Sepolia) and a Slack bot token.
