BlackBerry Protects Against RansomEXX Ransomware Attacks

A RansomEXX ransomware attack has paralyzed Ecuador’s state-run telecom provider Corporación Nacional de Telecomunicaciones (CNT) and prompted the Ecuadorian government to declare a state of “institutional emergency.” The attack left CNT security professionals scrambling to restore services and keep customers’ information safe.

First seen in mid-2020, RansomEXX is a ransomware variant designed to target Windows® OS users. Considered to be operated by a threat group dubbed Gold Dupont, RansomEXX is considered a “big-game hunter,” since it targets larger organizations that can afford to pay huge ransoms to get their compromised systems restored. The group has been linked to similar attacks on high profile victims, including Konica Minolta and The Texas Department of Transportation (TxDOT).

The cybercriminals behind RansomEXX appear to have ploughed some of their profits back into R&D, creating a Linux® version designed to target the Linux-based internal systems that many companies rely on in their production environments. This new method of attack has become a rising trend among big game hunter criminals, such as the groups behind recent attacks using Mespinoza (Pysa) and other ransomware variants.

BlackBerry Protects Against RansomEXX

The BlackBerry Research & Intelligence Team has analyzed the attack methods used by this threat, and in addition to recommending basic cyber hygiene steps, strongly urges BlackBerry customers to ensure their systems have the following BlackBerry® Cyber Suite components enabled with a blocking policy. 

BlackBerry Cyber Suite and BlackBerry Guard stop these attacks.
