DANGER SIKER Ransomware 🔐 (.DANGERSIKER File) — Removal Guide

The Danger siker virus belongs under the ransomware type of malicious agent. Ransomware of this type encrypts all the data on your computer (images, text files, excel tables, music, videos, etc) and adds its own extension to every file, creating the mesajin_var_amcik.txt files in every directory containing encrypted files.

What is Danger siker virus?

Danger siker will append its own .DangerSiker extension to every file’s name. For instance, a file entitled “photo.jpg” will be turned into “photo.jpg.DangerSiker”. In the same manner, the Excel file with the name “table.xlsx” will be changed to “table.xlsx.DangerSiker”, and so on.

In every folder with the encrypted files, a mesajin_var_amcik.txt text file will appear. It is a ransom money memo. Therein you can find information on the ways of paying the ransom and some other remarks. The ransom note usually contains a description of how to purchase the decryption tool from the ransomware developers. That is it.

How did Danger siker ransomware end up on my PC?

There are plenty of possible ways of ransomware infiltration.

Nowadays, there are three most exploited ways for criminals to have ransomware working in your system. These are email spam, Trojan injection and peer-to-peer networks.

  • If you access your inbox and see emails that look like familiar notifications from utility services providers, delivery agencies like FedEx, Internet providers, and whatnot, but whose “from” field is strange to you, be wary of opening those letters. They are very likely to have a malicious file enclosed in them. So it is even more dangerous to open any attachments that come with emails like these.
  • Another thing the hackers might try is a Trojan horse scheme. A Trojan is an object that gets into your machine pretending to be something legal. For instance, you download an installer of some program you want or an update for some program. But what is unboxed reveals itself a harmful agent that compromises your data. As the installation wizard can have any name and any icon, you’d better be sure that you can trust the resource of the things you’re downloading. The optimal way is to trust the software companies’ official websites.
  • As for the peer-to-peer networks like BitTorrent or eMule, the danger is that they are even more trust-based than the rest of the Web. You can never know what you download until you get it. Our suggestion is that you use trustworthy websites. Also, it is reasonable to scan the directory containing the downloaded items with the anti-malware utility as soon as the downloading is done.

How do I get rid of ransomware?

It is important to inform you that besides encrypting your data, the Danger siker virus will most likely install Vidar Stealer on your PC 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 avoid ransomware injection?

Danger siker ransomware has no endless power, so as any similar malware.

You can defend yourself from ransomware infiltration within several easy steps:

  • Ignore any emails from unknown mailboxes with strange addresses, or with content that has likely no connection to something you are expecting (how can you win in a money prize draw without even taking part in it?). If the email subject is likely something you are expecting, check all elements of the dubious email with caution. A hoax email will surely have mistakes.
  • Never use cracked or untrusted software. Trojan viruses are often distributed as a part of cracked products, possibly under the guise of “patch” which prevents the license check. Understandably, potentially dangerous programs are very hard to distinguish from reliable ones, because trojans sometimes have the functionality you seek. Try searching for information on this software product on the anti-malware message boards, but the best way is not to use such software.

🤔 What can I do right now?

  • If you sent or received your critical files via email, you could still download them from your online mailbox.
  • You may have shared photographs or videos with your friends or relatives. Just ask them to send those images back to you.

  • Maybe you still have the needed files on your old PC, a notebook, cellphone, memory stick, etc.

USEFUL TIP: You can employ file recovery programs1 to retrieve your lost information since ransomware arrests the copies of your files, deleting the original ones. In the tutorial below, you can see how to recover your files with PhotoRec, but be advised: you won’t be able to do it before you remove the virus with an anti-malware program.
