In response to such attacks, Google said last month that it reviews any OAuth abuse and takes down thousands of apps that violate its user data policy, including those that impersonate company products. Security experts have warned in the past that users may be phished through manipulation of OAuth to grant permissions to the wrong party. Talos has identified more than 275,000 applications that use OAuth and connect to the cloud.īut even though Tuesday's attack may have been novel, the dangers with OAuth are hardly new. "Like all other creative, novel approaches, it will likely be heavily copied almost immediately," Cisco's Talos security group said in a blog post.

However, security experts said Tuesday's phishing attack probably wasn't from Fancy Bear, a shadowy group that many experts suspect works for the Russian government. Last month, Trend Micro said a Russian hacking group known as Fancy Bear was using a similar email attack method that abused the OAuth protocol to phish victims. “The attack is quite clever and it exploits the ability for you to link your Google Account to a third-party application,” said Mark Nunnikhoven, vice president of cloud research at security firm Trend Micro.Įxploiting OAuth for account access is particularly devious because it can bypass the need to steal someone's login credentials or even Google's 2-step verification. ![]() The dummy app will try to ask for account permission.
