Cryptomining Campaign Returns Coal and Not Diamond

Summary: Cisco Talos recorded increased activity from the Lemon Duck cryptocurrency-mining botnet, which uses several methods to monetize compromised systems in less intrusive ways than ransomware. The same source notes a recent surge in cryptodrainer phishing attacks targeting cryptocurrency holders to trick them into divulging credentials.

What you should know: Lemon Duck shows that adversaries can monetize access quietly through cryptomining, without the headline-generating disruption of ransomware, so an intrusion that never triggers a ransom demand may still be running on your network.
