Hackers Use Social Engineering to Target Expert on Russian Operations

A new and highly sophisticated cyberattack, believed to be from a Russian state-linked group, has been revealed. This innovative method tricks people into creating and handing over App-Specific Passwords (ASPs), bypassing common security measures like Multi-Factor Authentication (MFA).

This sophisticated attack was jointly disclosed by the Citizen Lab (a research group at the University of Toronto) and Google’s Threat Intelligence Group (GTIG). Their investigation began after Keir Giles, a well-known expert on Russian information operations and a senior associate at Chatham House, contacted Citizen Lab for help after being targeted.

This new attack was different from typical phishing. It was slow and very convincing. It started on May 22, 2025, when Mr. Giles got an email from someone named Claudie S. Weber pretending to be a US State Department official. The email looked real, even with other official addresses in the “CC” line. The attackers took their time, sending over ten emails in several weeks to build trust. Experts think they might have used advanced tools to make their messages sound very natural.

The main trick was to get Mr. Giles to sign up for a fake MS DoS Guest Tenant platform. They sent him a professional-looking PDF with instructions. This PDF guided him to create an App-Specific Password (ASP)for his Google account.

For your information, an ASP is a special 16-digit code for older apps that don’t work with modern security. The hackers made it seem like this ASP would let him into a secure government system, but it actually gave them full control of his accounts.

GTIG has identified the group behind these attacks as UNC6293. They believe, with some certainty, that UNC6293 is connected to APT29 (aka Cozy Bear), a cyber espionage group linked to Russia’s Foreign Intelligence Service (SVR). Google later detected the attack on Mr. Giles’s accounts, took steps to secure them, and disabled the attacker’s email address.

This incident highlights a growing concern: as standard security like MFA becomes more common, attackers are finding new ways to bypass it. Experts expect more social engineering attacks that target App-Specific Passwords.

Cybersecurity teams are now advised to be wary of how ASPS are used in their organizations and to educate users about these new risks. Google is already working to phase out ASPs for business users in Google Workspaces but still balances security with user needs for personal Gmail accounts.
