Google discovered a new scam—and also fell victim to it

In June, Google said it unearthed a campaign that was mass-compromising accounts belonging to customers of Salesforce. The means: an attacker pretending to be someone in the customer's IT department feigning some sort of problem that required immediate access to the account. Two months later, Google has disclosed that it, too, was a victim.

The series of hacks are being carried out by financially motivated threat actors out to steal data in hopes of selling it back to the targets at sky-high prices. Rather than exploiting software or website vulnerabilities, they take a much simpler approach: calling the target and asking for access. The technique has proven remarkably successful. Companies whose Salesforce instances have been breached in the campaign, Bleeping Computer reported, include Adidas, Qantas, Allianz Life, Cisco, and the LVMH subsidiaries Louis Vuitton, Dior, and Tiffany & Co.

Better late than never

The attackers abuse a Salesforce feature that allows customers to link their accounts to third-party apps that integrate data with in-house systems for blogging, mapping tools, and similar resources. The attackers in the campaign contact employees and instruct them to connect an external app to their Salesforce instance. As the employee complies, the attackers ask the employee for an eight-digit security code that the Salesforce interface requires before a connection is made. The attackers then use this number to gain access to the instance and all data stored in it.
