A security expert has issued a warning to Microsoft email users about a surprisingly convincing phishing scam. According to Vsevolod Kokorin, whose online handle is Slonser, there is a bug that allows cybercriminals to make phishing scams look a lot more credible. This could mean victims may click on malicious links without realizing they’re part of a scam. Specifically, bad actors are able to mimic Microsoft corporate accounts – those ending in @microsoft.com – making it seem as though they are emailing from a credible source.
