Easy step by step .kr file virus removal guide
Kr or otherwise called .kr file virus is a Crypsis/Dharma ransomware family virus. It encrypts stored files and makes them inaccessible until a ransom payment is done. During encryption, it renames the files using .kr extension name plus a victims’ ID and email address belongs to the ransomware developers. For example, a file named 1.jpg becomes 1.jpg.id-1E857D00.[[email protected]].kr after being encrypted. Following to this, the ransomware creates a text file titled FILES ENCRYPTED.txt and drops it on desktop and displays a pop-up window.
The text file states that the files are encrypted and to return it, victims must need to contact the ransomware developers using [email protected] or [email protected] email address. The pop-up window provides further information. It states that the email that users write must include ID number provided to them. They can attach 1 encrypted file of their choice whose free decryption will be provided. However, to get all the files to be in decrypted form, they need to purchase a decryption tool. The price of this tool is not given on the ransom note. However, it is typically in between $500 and $1500 which is to be paid in Bitcoin or other form of Cryptocurrency. Unfortunately, this is not possible to decrypt the files without using a tool that kr developers have. As a rule, ransomware encrypts files using cipher algorithm that creates a unique key with each victim. The Crooks stored all the keys on some remote server. Another problem is that, Cybercriminals cannot be trusted. Quite often, they do not provide the decryption tool even if the payment is done. Thus, the safe way is to remove .kr file virus and recover the files using existing backup.
How did ransomware intrude inside my PC?
Although there is not a exact way for a ransomware intrusion, some observing techniques that are famous for ransomware distribution are mentioned below:
- Untrustworthy software downloading channels – these include third party downloaders, installers, p2p file sharing networks such as eMule and torrents, and free file hosting sites. They offer rogue applications for downloading presenting as legit software.
- Fake software updaters -System vulnerable caused by outdated software bugs/flaws could be a target for Cyber crooks. They exploit the bugs or directly download malware by using some fake software updaters
- Untrustworthy software activation tools- many cracking tools are also present that supposedly bypass activation key for paid software and cause computer infection. Using such tools is not legal.
Caution is important to achieve computer safety. Attentive enough when opening any emails, downloading/installing any files and when updating software. Use official source for any software download and update. Clicking on any irrelevant attachments is not recommended. Do not read the emails whose senders’ addresses seem suspicious.
