A campaign attributed to the FIN7 attackers targets restaurants with phishing emails and infected RTF Word documents that carry out fileless malware attacks.

Researcher Matt Nelson disclosed another Windows UAC bypass, this one abusing the sdclt.exe backup and restore utility to execute a payload without triggering an alert.
