SILENTANONYMOUS Virus (.SILENTATTACK File)

The Silentanonymous virus belongs to the ransomware type of malicious agent. Malware of this type encrypts all user’s data on the computer (photos, text files, excel sheets, audio files, videos, etc) and adds its extra extension to every file, leaving the Silent_Anon.txt files in each directory which contains the encrypted files.

Silentanonymous virus: what is known so far?

Silentanonymous will add its extra .SILENTATTACK extension to the title of every encrypted file. For example, an image entitled “photo.jpg” will be turned into “photo.jpg.SILENTATTACK”. Just like the Excel sheet with the name “table.xlsx” will end up as “table.xlsx.SILENTATTACK”, and so forth.

In each folder containing the encrypted files, a Silent_Anon.txt file will be found. It is a ransom money memo. Therein you can find information on the ways of contacting the racketeers and some other information. The ransom note most probably contains a description of how to buy the decryption tool from the racketeers. That is it.

How did Silentanonymous ransomware end up on my PC?

There are plenty of possible ways of ransomware infiltration.

Nowadays, there are three most exploited ways for hackers to have ransomware planted in your digital environment. These are email spam, Trojan infiltration, and peer networks.

• Another option for ransom hunters is a Trojan horse scheme. A Trojan is a program that infiltrates your PC disguised as something legal. Imagine, you download an installer for some program you need or an update for some program. But what is unpacked is a harmful agent that encrypts your data. As the update file can have any title and any icon, you'd better be sure that you can trust the source of the files you're downloading. The optimal thing is to trust the software companies' official websites.
• As for the peer-to-peer file transfer protocols like torrents or eMule, the threat is that they are even more trust-based than the rest of the Internet. You can never know what you download until you get it. So you'd better be using trustworthy resources. Also, it is a good idea to scan the directory containing the downloaded items with the antivirus as soon as the downloading is done.

How to remove ransomware?

It is crucial to inform you that besides encrypting your data, the Silentanonymous virus will probably install Vidar Stealer on your PC to seize your credentials to different accounts (including cryptocurrency wallets). The mentioned spyware can extract your logins and passwords from your browser's auto-filling data.

How do I avoid ransomware infection?

Silentanonymous ransomware doesn’t have a superpower, nor as any similar malware.

You can defend your PC from ransomware attacks with several easy steps:

• Ignore 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 even taking part in it?). If the email subject is likely something you are waiting for, scrutinize all elements of the suspicious letter. A fake email will always contain mistakes.
• Never use cracked or untrusted programs. Trojan viruses are often shared as an element of cracked software, possibly under the guise of a “patch” which prevents the license check. Understandably, potentially dangerous programs are difficult to distinguish from trustworthy ones, because trojans sometimes have the functionality you need. Try searching for information on this program on the anti-malware forums, but the best way is not to use such software.

FAQ

🤔 How can I open ".SILENTATTACK" files?Is it possible to open“.SILENTATTACK” files?

Negative. That is why ransomware is so frustrating. Until you decode the ".SILENTATTACK" files you will not be able to access them.

🤔 I need to decrypt those “.SILENTATTACK” files ASAP. How can I do that?

If the “.SILENTATTACK” files contain some really important information, then you probably have them backed up. In case you haven't, there is still a chance that you do have a Restore Point from some time ago to roll back the whole system to the moment when it had no virus yet, but already had your files. All other solutions require time.

🤔 What should I do if the Silentanonymous virus has blocked my computer and I can't get the activation key?

🤔 And what should I do now?

Some of the blocked files can be located elsewhere.

• If you sent or received your important files via email, you could still download them from your online mailbox.
• You might have shared photographs or videos with your friends or family members. Simply ask them to send those pictures back to you.
• If you have initially downloaded any of your files from the Web, you can try downloading them again.
• Your messengers, social networks pages, and cloud storage might have all those files too.
• Maybe you still have the needed files on your old computer, a portable device, mobile, flash memory, etc.

HINT: You can use data recovery utilities¹ to get your lost data back since ransomware blocks the copies of your files, removing the original ones. In the video below, you can see how to use PhotoRec for such a restoration, but be advised: you can do it only after you eradicate the ransomware itself with an antivirus program.
