ATCK Virus ([email protected]) Ransomware Removal

The Atck virus belongs under the Dharma ransomware family. Harmful software of such sort encrypts all user’s data on the PC (photos, documents, excel sheets, audio files, videos, etc) and adds its specific extension to every file.

What is known about the Atck virus?

☝️ Atck is a Dharma family ransomware virus.

The scheme of renaming is the following: .ATCK. After the encryption, a file entitled, for example, “report.docx” will be altered to “report.docx.id[05C1E846-D115].[[email protected]].ATCK”.

The ransom note most probably contains instructions on how to purchase the decryption tool from the ransomware developers. You can obtain this decoding tool after contacting [email protected] via email. That is basically the scheme of the malefaction.

In the screenshot below, you can see what a folder with files encrypted by the Atck looks like. Each filename has the “.ATCK” extension appended to it.

How did my computer get infected with Atck ransomware?

There are many possible ways of ransomware injection.

There are currently three most exploited ways for evil-doers to have the Atck virus planted in your digital environment. These are email spam, Trojan introduction and peer file transfer.

• Another thing the hackers might try is a Trojan virus model. A Trojan is an object that infiltrates into your computer pretending to be something legal. Imagine, you download an installer for some program you want or an update for some software. However, what is unboxed turns out to be a harmful program that encrypts your data. As the installation package can have any title and any icon, you have to make sure that you can trust the source of the things you’re downloading. The optimal way is to trust the software developers’ official websites.
• As for the peer file transfer protocols like torrents or eMule, the danger is that they are even more trust-based than the rest of the Internet. You can never guess what you download until you get it. So you’d better be using trustworthy websites. Also, it is reasonable to scan the folder containing the downloaded objects with the antivirus as soon as the downloading is complete.

How do I get rid of ransomware?

It is important to note that besides encrypting your data, the Atck virus will probably install Vidar Stealer on your machine to get access to credentials to various accounts (including cryptocurrency wallets). The mentioned spyware can extract your credentials from your browser’s auto-filling cardfile.

How сan I avert ransomware infection?

Atck ransomware has no superpower, so as any similar malware.

You can defend your PC from its attack taking several easy steps:

• Never open any letters from unknown mailboxes with unknown addresses, or with content that has nothing to do with something you are waiting for (can you win in a lottery without participating in it?). If the email subject is more or less something you are expecting, scrutinize all elements of the dubious letter with caution. A fake letter will always have a mistake.
• Do not use cracked or untrusted software. Trojans are often distributed as a part of cracked products, possibly under the guise of “patch” which prevents the license check. Understandably, untrusted programs are difficult to distinguish from reliable ones, because trojans may also have the functionality you seek. You can try to find information on this program on the anti-malware forums, but the optimal way is not to use such programs at all.
