The fetched bytes are written under /tmp or %TEMP% with a disguised filename (`.cache_<hex>` or `dotnet_diag_<hex>.exe`), chmodded 0755, and spawned detached via `/bin/sh -c` or `cmd.exe`. The C2 host strings and the `child_process` module name are split across array joins (`["oob-worker.cf103-070.wo","rk","ers",".de","v"].join("")`, `require("child_"+"process")`) to evade static matching. Cover-story identifiers (`analytics_state`, `DISABLE_TELEMETRY`) frame the drop as telemetry. A second, structurally identical dropper ships in lib/telemetry.js (~81 KB) dressed as an analytics SDK: dynamic `require("child_"+"process")`, base64 buffer reassembly, `chmodSync(..., 0o755)`, and `cp.spawn("/bin/sh", ["-c", filePath+" &"],...)`. ## Source: ghsa-malware (176764d97e59476107ea84a11437ba6719446a8f96682c7c6f46284e15f284a1) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
AI Analysis
Technical Summary
This threat involves a malicious npm package, dolyame-boxy-desktop-bnpl-card-gallery version 35.5.2, which upon being required, loads a script that downloads a platform-specific binary from hardcoded Cloudflare Workers domains. It uses a DNS-TXT fallback mechanism to reassemble a base64-encoded payload from TXT records hosted on several domains. The payload is written to temporary directories with disguised filenames, permissions are set to executable, and the binary is executed detached via shell commands. The code obfuscates critical strings such as command-and-control hosts and the child_process module name by splitting and joining string arrays to evade static detection. A second similar dropper is embedded in a telemetry-like module, further disguising the malicious behavior as analytics SDK functionality.
Potential Impact
The malicious package can execute arbitrary code on the host system by downloading and running binaries from attacker-controlled servers. This can lead to full system compromise, unauthorized remote code execution, and persistence. The use of obfuscation and fallback DNS-TXT channels complicates detection and mitigation efforts.
Mitigation Recommendations
No official patch or remediation is currently documented for this package version. Users should avoid using version 35.5.2 of dolyame-boxy-desktop-bnpl-card-gallery. Remove any installations of this package and audit systems for signs of compromise. Monitor for suspicious network connections to the indicated domains. Since no vendor advisory or patch is provided, patch status is not yet confirmed — check the vendor advisory or trusted security sources for updates.
