Malware Campaign Baits Users Into Bypassing Browser Warnings Using Clever Captcha

Malware campaign that uses a clever captcha to download the Gozi (aka Ursnif) banking trojan has been discovered by the security researcher MalwareHunterTeam.

When opening the malicious link, a video about NJ prison is opened, while the file console-play.exe is being downloaded and the site will display a fake reCaptcha image on the screen.

Since the file that is being downloaded is a .exe file, Chrome would usually warn users of it, asking whether they want to keep or discard it, which is why fake reCaptcha is used.
