Microsoft today warned users of the dangers behind spear phishing attacks used by threat actors to target specific individuals, in their attempts to infect them with malware, harvest sensitive information, or trick them into making fraudulent payments.

While regular phishing campaigns aren't picky and use a shotgun spray approach in the hopes of successfully compromising as many targets as possible, spear phishing attacks use messages customized for a single target.

"They are so targeted, in fact, that we sometimes refer to them as 'laser' phishing," Microsoft says. "And because these attacks are so focused, even tech-savvy executives and other senior managers have been duped into handing over money and sensitive files by a well-targeted email. That’s how good they are."
