Ykcol virus is a subsequent version of Locky crypto-virus following Diablo6 and Lukitus variations. Likewise, it employs RSA-2048 and AES-128 algorithms. After completing the encryption process, all data is marked with .ykcol file extension and leaves ykcol.bmp and ykcol.html files.

The former file will be set as the background picture informing about the locked data; the .html file will open up in the browser. It includes links in order to assist victims with the payment procedure.

Following the manner, the developers ask victims to install Tor browser and access a specific .onion site and promotes Locky Decrypter. The latter software has been promoted since the emergence of the original version. The initial demanded ransom was 0.25 bitcoins, but recently, the cyber villains have increased the amount again up to 0.5 which amounts to £1300.

The new version does not exhibit any new features. This time developers did not bother themselves making up an elaborate name as they simply reversed the name Locky backwards. The felons also stick to the same distribution campaign – spam emails.

Therefore, you can attempt to recover data using third-party tools or use backups. Before that, remove Ykcol virus. FortectIntego or Malwarebytes will be of assistance.

The malware also exhibits a tendency to use Necurs botnet to send out emails with the ominous attachments. In addition, this version ceased to use C2 server and now limits itself to operating offline.

It is highly recommended to eradicate the ransomware a soon as possible. In addition, do not get tempted to install Locky Decrypter as it may only facilitate the hijack of the system in the future.

Spam technique remains the same with few modifications

Since the beginning, Locky developers maintained the same tendency to disguise Locky ransomware in a supposed invoice. Ykcol variation does not differ much either. However, Lukitus version manifested a new feature to deliver the malware in a .7z folder. It contains a VBS script which accelerates the execution of the malware.

The counterfeited messages are supposed sent by the representatives of official institutions. Some of such emails ask users to verify the content of the attached invoice. Locky developers also target company servers and plague them with spam emails containing fake scanned images.

They are named as ‘scanned picture of printer [model].’ Likewise, escaping the menace delivered in such method might turn out quite challenging. Few employees might notice that the name of the printer mismatches with the one present in the company.

In overall, it is necessary to only remain vigilant while coping with these spam emails, but ensure cyber security. Some anti-virus and malware elimination tools grant users the feature of spam filtering and reducing the number of such messages.

How to prevent from getting ransomware

Securely connect to your website wherever you are

Sometimes you may need to log in to a content management system or server more often, especially if you are actively working on a blog, website, or different project that needs constant maintenance or that requires frequent content updates or other changes. Avoiding this problem can be easy if you choose a dedicated/fixed IP address. It's a static IP address that only belongs to a specific device and does not change when you are in different locations. 

VPN service providers such as Private Internet Access can help you with these settings. This tool can help you control your online reputation and successfully manage your projects wherever you are. It is important to prevent different IP addresses from connecting to your website. With a dedicated/fixed IP address, VPN service, and secure access to a content management system, your project will remain secure.

Reduce the threat of viruses by backing up your data

Due to their own careless behavior, computer users can suffer various losses caused by cyber infections. Viruses can affect the functionality of the software or directly corrupt data on your system by encrypting it. These problems can disrupt the system and cause you to lose personal data permanently. There is no such threat if you have the latest backups, as you can easily recover lost data and get back to work.

It is recommended to update the backups in parallel each time the system is modified. This way, you will be able to access the latest saved data after an unexpected virus attack or system failure. By having the latest copies of important documents and projects, you will avoid serious inconveniences. File backups are especially useful if malware attacks your system unexpectedly. We recommend using the Data Recovery Pro program to restore the system.
