WARDEN scanner bypasses fixed after punctuation and IP reuse bugs surfaced

The WARDEN security scanner has identified two vulnerabilities related to how it processes sensitive information. One issue involved the scanner failing to detect requests for private keys when a period was appended to the phrase, allowing malicious actors to bypass detection. Another bug occurred when a network observer incorrectly attributed traffic from one sandbox run to another due to a reused IP address and matching timestamp. Both issues were discovered through reader suggestions and have been addressed by refining the scanner's rules to better distinguish between arguments and tool descriptions, and by adjusting how punctuation is handled at the edge of identifiers.
