Malicious npm package 'indexed-btree' bypasses install defenses

A malicious npm package with 2M weekly downloads evades install defenses, plus OpenAI Codex sandbox escapes and a CVSS 9.8 REDCap RCE.

  • Malicious npm package 'indexed-btree' hides malware in runtime code to bypass install defenses
    A malicious npm package called 'indexed-btree' evades npm's install-script defenses by triggering its malware loader at runtime.

    • Targets developers using npm; the fake 'indexed-btree' package impersonates the legitimate 'sorted-btree' library and amassed 2 million weekly downloads, with nine related packages also removed from npm.
    • The malware hides in the package's BTree.prototype.set() method, executing only when the app calls it with a specific key, so installation appears clean and bypasses npm v12's lifecycle-script approval checks.
    • Once triggered, it collects system details (architecture, hostname, CPU, memory, uptime) and exfiltrates them via hardcoded Slack and Telegram channels.
    • It polls an Ethereum smart contract on the Sepolia test network for C2 info, using X25519 key exchange to derive an AES key and decrypt a second-stage payload, and can delete its files and remove the trigger to wipe traces.
    • The operators built a legitimate-looking GitHub repo with fabricated commit history and a curated developer account; Checkmarx says the attackers' wallet holds 109 ETH.

  • Researchers escape OpenAI Codex sandbox to run commands on host
    Researchers found two sandbox escape vulnerabilities in OpenAI Codex, both now patched.

    • Applies to developers using OpenAI Codex CLI agent, including its most locked-down sandbox mode.
    • Two sandbox escapes allowed running arbitrary commands on the developer's host machine.
    • OpenAI has patched both escape methods.
