KwaakLocked ransomwareKwaakLocked is a ransomware which is related to the infamous HiddenTear virus

KwaakLocked is a file locking virus and is a variant of the infamous HiddenTear ransomware. Malware uses the AES-256[1] encryption algorithm to encrypt files and appends .kwaaklocked file extension, making them unusable. As soon as that is done, the virus drops a ransom note READ_IT.txt into each of the affected folders.

The malicious payload is carried inside spam email[2] attachments. Computer users might get a suggestion to open the attachment by enabling macro function, which should never be allowed. Additionally, malicious emails can contain hyperlinks that can automatically download and install KwaakLocked ransomware. The fake messages can come as invoices, bank statements, and similar.

When the installation is finished, KwaakLocked virus scans the system and looks up for files to encrypt. It skips system files, and some other file types, however. The virus targets personal data, including databases, Excel spreadsheets, images, video and audio files, etc. The example of the encrypted file is as follows: picture.jpg is turned into picture.jpg.kwaaklocked, making it unusable.

To decrypt files, users need a decryption key that is sent to Command and Control server used by hackers. Nevertheless, there are other ways to get files back. But before that, you need to make sure that KwaakLocked removal is performed promptly. For that, we advise using FortectIntego or SpyHunter 5Combo Cleaner anti-malware software.

What is particularly interesting is that the ransomware authors do not give any information about where the Bitcoins should be transferred to, neither do they provide any contact email:

Files has been encrypted with kwaak
Send me some bitcoins

Nevertheless, even if contact details would be provided, users should always ignore hackers, as they are known to even ignore victims after payment is transferred. Thus, users may end up with no access to their files, as well as wasted money. Besides, paying cybercriminals may promote to lock up more PCs in order to receive more payments.

The Kwaaklocked virus might appear as “hidden-tear.exe” on the infected system's Task Manager, and different AV engines detect the malware under different names, including Ransom.HiddenTear!g1, Gen:Heur.Ransom.HiddenTears.1, Ransom.HiddenTear/Variant etc.

The virus is also known to delete Shadow Volume copies from the targeted machine, although in some cases the virus may fail to accomplish that. Nevertheless, there are numerous ways you can try to recover your files, including using third-party software. Nevertheless, you have to remove KwaakLocked from your computer before you make attempts to recover your data. Otherwise, the backup data will be encrypted as well.

How to prevent from getting ransomware

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

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.
