Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis No additional public attack-surface or AI-review details are available. ## Affected versions and remediation This report applies to ordered-btree@3.2.2. - Avoid installing ordered-btree@3.2.2. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% Package impersonates the legitimate sorted-btree library (matching name, README, and attributed author) and ships a hidden remote-code-execution payload in its primary API. b+tree.js modifies BTree.prototype.set so that when a caller invokes tree.set(100,...), it spawns \`node extended/diffLoad.min.js\` as a detached process. diffLoad.min.js is a heavily obfuscated loader that connects to Ethereum Sepolia (via hardcoded Infura/Alchemy RPCs), reads encrypted payload chunks from contract 0xE390863Dac96a71187C71227C2b099B50cF602D31 (TData1/TData2 events), decrypts them with x25519 ECDH + AES-GCM, writes the decrypted bytes to extended/merged, chmods to 755, and executes that file as a detached child process — using a public blockchain as rotatable, blocklist-evading C2. The loader also harvests host telemetry (platform, release, arch, hostname, cpus, totalmem, freemem, uptime) and exfiltrates it to a hardcoded attacker Telegram bot (bot id 8961878831 at api.telegram.org/bot\/sendMessage) and to slack.com/api/chat.postMessage with hardcoded credentials, including a message derived from the LICENSE file. After execution, it removes its own files (diffLoad.min.js, extended/bulkLoad.min.d.js, extended/diffLoad.d.min.js) and rewrites b+tree.js to splice out the 16-line trigger block starting at line 249, then signals the parent process (SIGTERM/taskkill) — anti-forensic clean-up so the installed package looks benign after the payload has run. Any application that drop-in-replaces sorted-btree with ordered-btree and exercises set with key 100 (e.g., tests, fixtures, or production data containing that key) will fetch and execute attacker-controlled code on the installer's machine. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** ordered-btree - **Ecosystem:** npm - **Version:** 3.2.2 - **Version published:** Not available - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 1 - **Latest version:** 3.2.2 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]()
