command echo -e '{"id":1,"jsonrpc":"1.0","method":"%n"}' | nc 192.168.1.139 3333 & printf "\n"↗

• → Monitor TCP port 3333 for inbound JSON-RPC requests containing format string specifiers (e.g., %n, %s, %p) in the 'method' field, which indicates active exploitation of CVE-2018-6317. ↗
• → Unauthenticated access to the remote management interface on port 3333 is the attack vector; detect any external/unauthenticated connections to this port on mining hosts. ↗

• · The vulnerability affects Claymore Dual Miner version 10.5 and earlier only; version 10.6 contains the patch. Ensure miners are updated to 10.6+. ↗
• · Exposing port 3333 publicly is the primary risk factor; restricting this port to trusted networks eliminates the remote attack surface entirely. ↗
