New Petya Ransomware Makes Disruptive Debut
Spanning back to the early 1990s and making a brief reappearance in early 2016, a variant of Petya (also called Petrwrap) Ransomware has resurfaced once again, this time referred to as Petya A or NonPetya. As far as what is already known about the recent attack which hit companies, public health care and governments organizations, as well as airports in the U.S., Russia, Ukraine, Germany, France, Italy, Poland and the UK, the newer and more robust version was inspired by the recent WannaCry Ransomware attack in May. With this particular Ransomware, criminals do not encrypt all files on your computer, but rather attack a part of the operating system called the Master File Table (MFT), which then overwrites the MBR (Master Boot Record). Much like the WannaCry Ransomware attack, the virus requires the victim to pay a digital ransom through Bitcoin in order to regain control.
Impact of Petya
The MFT is critical for the system to know where to find files on the computer. It holds the same effect as if each file had been locked separately. Why is this significant? It is a lot faster to attack the MFT than to encrypt each file separately – making this a seamless and fast-moving attack.
According to researchers at the computer security company, Symantec, the new attack is using the same hacking tool (Eternal Blue) that was initially created by the National Security Agency (NSA) to combat the WannaCry Ransomware. The tool was leaked last April by a group known as the Shadow Brokers.
According to a researcher at Armor, the Petya attacks are projected to be much more damaging than WannaCry. There is no obvious killswitch with this virus, which has proven to be difficult in mitigating the effects. Because this version of Petya carries significantly upgraded features, it is expected to infect the latest and even patched Windows PCs, including version 10, whereas WannaCry focused primarily on older systems.
If infected by Ransomware…
Even with the best precautions and policies in place, it is possible to fall victim to an attack. In the event that your data is held hostage by Ransomware, here is some advice to keep in mind:
- Remain calm. Rash decisions could cause further data loss. For example, if you discover a Ransomware infection and suddenly cut power to a server, versus powering it down properly, you could lose data in addition to the infected data.
- Check your most-recent set of backups. If they are in-tact and up-to-date, the data recovery becomes easier to restore to a different system.
- Never pay the ransom because attackers may not unlock your data. We mentioned this earlier on. There are many cases of Ransomware victims paying the ransom demanded and not receiving their data in return. Rather than running this risk, companies should work with data recovery experts who may be able to regain access to the data by reverse engineering the malware.
- Contact a specialist for advice and to explore recovery options. We can examine your scenario to see if we have a solution already in place or if we are able to develop one in time.
To date, engineers at Kroll Ontrack have identified over 225 variations of Ransomware that infect user devices and there are more variations created every day, plus others that may not have been reported already. The team of engineers at Kroll Ontrack work around the clock to identify and find a solution for each type of Ransomware. There is hope for those who are infected with Ransomware.
