A joint cybersecurity advisory from the German Federal Office for the Protection of the Constitution and the National Intelligence Service of the Republic of Korea warn about Kimsuky's use of Chrome extensions to steal target's Gmail emails.
Kimsuky is a North Korean threat group that uses spear phishing to conduct cyber-espionage against diplomats, journalists, government agencies, university professors, and politicians.
The extension is named 'AF' and can only be seen in the extensions list if the user enters "(chrome|edge| brave)://extensions" in the browser's address bar.
Once the victim visits Gmail through the infected browser, the extension automatically activates to intercept and steal the victim's email content.
This is not the first time Kimsuky has used malicious Chrome extensions to steal emails from breached systems.
In July 2022, Volexity reported about a similar campaign using an extension named "SHARPEXT." In December 2018, Netscout reported that Kimsuky was following the same tactic against academia targets.
