Are there any useful apps/sites that could provide some sort of risk score for hyperlinks embedded in emails or elsewhere. e.g. the potential impact of clicking it? I've got a batch of 'suspect' email messages in a PST archive currently stored on an offline device (no Internet connection) and I was interested in analyzing the links within the messages, to identify the possible threat of clicking them or the destination site.
Or if you were to do a manual review, is there much that can be done visually on a URL behind a hyperlink to identify the possible threat of clicking it. What specific characteristics would you look for in the link to raise suspicions?
