What is Symbiom ransomware virus?

Things you must know about Symbiom

Symbiom virus

Symbiom virus has recently been brought to the spotlight after it was spotted infecting computers disguised as an illegal video game activation software (crack [1]). In particular, the victims claim to have downloaded a file called OverWatch_Hack.exe hoping to play the OverWatch game for free.

Unfortunately, what they are actually dealing with is a variant of the HiddenTear ransomware virus.

After opening the malicious file, victims lose access to a large portion of data stored on the computer. The data primarily includes victims personal files such as Office documents, archives, video/audio and image material, etc. Besides, the virus appends all encrypted files appended with .symbiom_ransomware_locked extensions.

The worst part of this is cyber infection is that even after Symbiom removal, the data remains encrypted. On the other hand, the cleanup procedure is necessary in case virus victims wants to continue using their devices normally again. Software like FortectIntego can be used for this purpose.

Symbiom virus depictionIn the Symbiom virus depiction above you can see a ransom note that the virus drops on the computers to demand ransom.

Among the documents the OverWatch virus will drop on the computer is a ransom note called README_Ransomware_Symbiom.txt. In this note, criminals demand 0.1 Bitcoin ransom. They also indicate the Bitcoin wallet address to which the ransom should be transferred and provide an email address for further communication with the victim. The full note reads:

Your files have been locked by Symbiom!
Send 0.1 bitcoin (It is about 250 dollars) to: [Bitcoin wallet address edited out]
Afterwards, send your bitcoin address which you payed with to :
Don’t worry. I will save your files if you pay.

While the 250 dollar ransom may not seem particularly large, given the fact that it gives back the ability to regain access to your data, paying is strongly unrecommended. When dealing with the criminals, there are no guarantees that your files will be restored even when you pay the money. Thus, it is wiser to remove Symbiom from the PC before establishing any contact with the criminals.

Ransomware distribution or how the virus infiltrates computers

Symbiom is a software attributable to the category of probably the most serious cyber infections — ransomware. These parasites are especially sneaky when it comes to infiltrating computers. Malware creators think of numerous ways to place the malicious codes on the system.

As Symbiom spreads disguised under OverWatch crack file, it is likely that its download links will show up on peer-to-peer networks [2], gaming forums, and similar sources.

Nevertheless, there are other ways the destructive payload can reach computers. For instance, it may be embedded through system or software vulnerabilities detected by exploit kits, fake software updates, compromised online advertisements or spam. So be careful out there!

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
