You mentioned earlier that ClamAV has recently added signatures from PhishTank, but I've noticed over the last few days that most, if not all of them have been removed. Should I conclude that the PhishTank organization signatures are resulting in a high False Positive count? Are they simply accepting all the submissions they get as valid fishing attempts and not QAing them before release?
Part of my interest is that I've been providing input to them for years after first establishing that the spam e-mail I received is from an address that doesn't match the purported notice of impeding doom and offer to fix by clicking a link which does not match the announced domain? I'm not sure all users would go to such lengths and might be forwarding all their spam to these folks. Or perhaps some are flooding the site with valid url's in an attempt defeat their purpose. -Al- On Tue, Dec 11, 2018 at 08:01 PM, Micah Snyder (micasnyd) wrote: > Hi Sunny, > > I meant to say that if I scanned a saved email file containing the malicious > URL in an HTML link (i.e. a href=link ), then it will detect the link with > the safebrowsing signature.
