Read MoreImagine you’re a military leader. What if I offered you a weapon to cleanly take out enemy infrastructure with minimal incidental civilian deaths? It has near-infinite operational reach and it’s highly stealthy. Oh, and it’s cheap compared to say, strategic missiles, which cost about a million or so dollars apiece.1 Well, have I got a…
Read MoreWhile investigating a recent threat campaign, F5 researchers encountered a strange behaviour where malicious requests were originating from legitimate Googlebot servers. This relatively infrequent behavior could potentially have serious consequences in environments where the trust level given to Googlebot influences an organization’s security decisions. The Trust Paradox Google’s official support site advises to “make sure…
