This detection rule is designed to identify emails containing links to domains with Punycode characters. Punycode is an encoding scheme that allows non-ASCII characters to be represented in web addresses, potentially enabling attackers to disguise malicious links as legitimate ones. This rule checks the body of incoming emails for links where the domain is valid and encoded using Punycode, signifying an attempt to mask the true destination. Additionally, the rule incorporates conditions related to the sender, specifically focusing on messages from 'WordPress' or scenarios where the sender profile indicates a likelihood of being malicious or unsolicited. By applying sender analysis and URL analysis techniques, the rule aims to detect potential credential phishing attempts through the detection of lookalike domains and other evasion tactics.
