Today’s Field Note
Wallets tied to April’s $295M Drift exploit have pushed $109M in ETH through Tornado Cash over two days, including another $46M on Wednesday, with roughly $138M in ETH still sitting in attacker-controlled addresses. That is not a rumor or a reorg risk, it is active laundering of stolen funds, which means tainted ETH is entering circulation now. Separately, PHP shipped an out-of-cycle fix at 14:00 UTC for two critical RCE flaws (CVSS 9.2) dubbed PHP2Shell, and the widely shared workaround was disowned by the firm that suggested it. If you run any PHP-facing infrastructure (RPC proxies, dashboards, webhook endpoints, exchange or wallet backends), the only real mitigation is the patch.
Today’s Move
- Patch PHP today. Pull the official out-of-cycle release and update every PHP-facing service (node proxies, admin panels, webhook receivers). Do not rely on the config-only workaround, the vendor retracted it.
- Flag Drift exploiter addresses in your compliance and treasury screening. Expect freshly mixed ETH from Tornado Cash exits and tag inbound deposits accordingly.
- If you operate an exchange or custodian, review ETH deposits for post-mixer provenance over the coming days rather than assuming clean history.
- Audit UpdraftPlus/UpdraftCentral installs on any WordPress property you own. TeamUpdraft’s connection keys were compromised and used to backdoor sites, so rotate keys and check for unexpected admin users.
- If you run SSH over Tor, assume October 1 to 5 password logins were intercepted via hijacked exit relays. Rotate those credentials and move to key-based auth.
