Tricky Phish Angles for Persistence, Not Passwords

Late last year saw the re-emergence of a nasty phishing tactic that allows the attacker to gain full access to a user’s data stored in the cloud without actually stealing the account password. The phishing lure starts with a link that leads to the real login page for a cloud email and/or files storage service. Anyone who takes the bait will inadvertently forward a digital token to the attackers that gives them indefinite access to the victim’s email, files, and contacts — even after the victim has changed their password.

Before delving into the details, it’s important to note two things. First, while the most recent versions of this stealthy phish targeted corporate users of Microsoft’s Office 365 service, the same approach could be leveraged to ensnare users of many other cloud providers. Second, this attack is not exactly new: In 2017, for instance, phishers used a similar technique to plunder accounts at Google’s Gmail service.
