Google says North Korean hackers exploited a RCE vulnerability in Chrome

Google Chrome is one of the most widely used browsers on the planet with billions of users. With that kind of use base, cybersecurity is definitely one of the concerns.

Google recently warned its users about the incoming exploits coming from state-sponsored hackers from North Korea. The vulnerability was detected by the Threat Analysis Group (TAG) on January 4th this year when they found out about an exploit kit deployed on the browser.

The tech giant reported another instance of an attempt on February 10 but from a different North Korean hacking team.

As the report reads, these hackers were particularly targeting fintech outlets, U.S.-based news, cryptocurrency, and IT establishments.

Google finally released a patch on February 14 to plug the vulnerability.

As per how the exploit would happen, users would receive emails from hackers disguised as job aggregators like Oracle, Google, and Disney.

Here, the attacker’s website would act as a duplicate site resembling that of Indeed or ZipRecruiter where the victim could open the links with a hidden iframe located on it.

Apparently, the exploit kit on the targeted system will collect all the data regarding user-agent, resolution, and others.

The data is set to the exploitation server where the Chrome RCE will be analyzed and if successful, it will trigger a script called ‘SBX’. The hackers are using state-of-the-art methods such as using AES-based encryption during exploitation steps, using iframe to open during time slots when the user is expected to visit a website, etc.

For now, Google has released the remote code execution (RCE) vulnerability as of February 14th. The users are required to update their browsers to get the latest patch installed on their systems.
