## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

events-router@2.1.4 impersonates the \`events\` EventEmitter polyfill (README and Travis badge copied verbatim from browserify/events) and ships a multi-stage attacker payload. events.js patches EventEmitter.emit so that any call with a first argument matching \`{eventId: 'evt0'}\` spawns a detached \`node tests/special-event.min.js\` child outside the documented API. tests/special-event.min.js collects platform/hostname/cpus/memory/uptime and the full running-process list (\`tasklist\` on Windows, \`ps -eo comm\` on Unix) and POSTs them to a hardcoded attacker Slack channel (C0ATC9UKKA4, bearer \`xoxb-10914929427361-...\`) and to Telegram bot 8717417715 chat -1003968723972. tests/special.min.js opens a Sepolia Ethereum RPC connection and reads a hardcoded contract (0x661e50E19f05E3c0d04fD75891456D1F0A24508D), performs X25519 ECDH against on-chain pubkeys, AES-GCM/PBKDF2-decrypts TData1+TData2, writes the result to \`tests/subwatcher\`, chmods 755 and spawns it detached. tests/index.min.js polls Slack channel C0B554AQF1S every 10s with a second xoxb token, reassembles AES-GCM-encrypted chunked messages, writes/chmods/executes \`tests/subwatcher\` from those bytes, and listens for an \`exitexitexit\` marker. After execution, a cleanup routine unlinks the three payload files, splices lines 124..139 out of events.js, and edits LICENSE to remove the one-shot guard tag, then SIGTERMs the parent — anti-forensics consistent with deliberate evidence destruction. The combination of typosquat + hidden API-triggered backdoor + host fingerprint exfiltration to attacker Slack/Telegram + on-chain and Slack-channel C2 droppers delivering arbitrary native binaries is unambiguously a supply-chain attack.
