Small but powerful — shortened URLs as an attack vector

Using tiny URLs to redirect users to phishing and malware domains is nothing new, but just because it’s a common delivery tactic doesn’t mean that attackers aren’t using it to deliver new malware samples. We recently received a report of a phishing email from one of our users here at PhishMe that employed a shortened google URL, and led to some surprising malware.

Through the power of user reporting, we received the report, discovered the malicious nature of the shortened URL, and reported the issue to Google – all within a span of 30 minutes. Google reacted quickly and took the link down shortly after our report.
