Ransomware Alert: BadRabbit is the New NotPetya

A new ransomware attack from the actors behind ExPetr/NotPetya has jumped into the spotlight. The outbreak began in Russia, infecting big Russian media outlets, but it has already spread. Several US and UK firms, with corporate entities in the Ukraine and Russia, have already been infected. An increase of US infections is expected. BadRabbit is currently running wild over Europe, thanks to its close ties to the source region.The US computer emergency readiness team has released a statement and “discourages individuals and organizations from paying the ransom, as this does not guarantee that access will be restored.”

Several security agencies are reporting that a false Adobe Flash Update is the infection method. Without utilizing exploits, the ‘drive-by’ attack tricks the victim into downloading the fake installer from a convincing website. The victim, assuming it is a legitimate Flash update, then manually launches the .exe file. From there, BadRabbit has a hold of the device and can spread to more devices on the connected network.

There are several recommended steps for stopping the spread of this new ransomware. The first step is to disable WMI Service to prevent the hopping of ransomware throughout your connected networks. It may be inconvenient, but especially if you have offices in the Ukraine or Russia, disabling that connection could be the key to preventing your entire company from being infected.

There is also now a ‘vaccine’ for BadRabbit. The security researcher Amit Serper posted his findings on Twitter.The tweet reads: “I can confirm – Vaccination for #badrabbit: Create the following files c:windowsinfpub.dat && c:windowscscc.dat – remove ALL PERMISSIONS (inheritance) and you are now vaccinated.“With a software distribution solution, like Syxsense, you can easily deploy this file to every device you manage. Utilizing the simple deployment wizard, you can have a task running in seconds to protect your environment.
