Ykcol is but a spin-off of Locky ransomware, the latter has been around for a couple of years. In terms of encryption-for-ransomware, Locky is a long-liver.
Ykcol represents a reverse order of writing for Locky. Perhaps the crooks want to see if the victims and experts trace the link. In fact, IT security observes there is rather no such ransomware as Ykcol; all-in-all it is just another hallmark attached by Locky virus to the files it encrypts.

Meanwhile, the ransomware evolves, at least in terms of its infection vectors. As an old one, the Locky trojan has long since been available as a RaaS (Ransomware-as-a-Service). That is, any potential scammers may get a copy of the virus to distribute, backed with the support of master crooks. This implies a freedom of distribution tactics that the wannabe hackers are free to follow; in the wild, however, one particular technique prevails.
Most of the victims have their devices affected with the ransomware as they receive a spam email. The message title reads ‘Subject of Invoice’, the body is a request to notify its status. The poison is, as usual, hides in the content attached. In this case, the attachment is a 7zip archive. Its unpacking drops the ransomware downloader, which contacts the remote server to download the infection and ensures its further installation. Hopefully, many devices block the invasion at one of the points prior to the encryption stage.
Files encrypted by .ykcol ranomware
The infection scrambles both file names and contents. A name transforms in a long sequence of digits that has no traceable link to the source. There is currently no master key to undo the encryption caused by Ykcol variant of Locky ransomware.
Ykcol virus removes itself, once the encryption payload completes. Instead, it creates its ransom note dropping its copies at the Desktop and at every folder that contains the files hits by the virus.
This informs the users that RSA and AES ciphers have encrypted their data. To undo the modification, the trojan eventually demands .25 BTC to a bitcoin wallet specified. The sum currently converts to fiat currency at a rate of 4,000 USD per 1 BTC, hence amounts to 1,000 USD.
A set of data recovery routines tailored for Ykcol variant of Locky ransomware follows.
Automated cleanup to remove Ykcol virus
Infection vector for ransomware typically features a trojan. The one in question definitely subscribes to that routine. The trojan drops its body into target computer and proceeds with disabling the detecting functionality of any security solution installed. The antivirus is thus unable to spot introduction of virus from the remote server.
The ransomware invasion is indicative of its dropper residing in the computer memory. It also hints at other invasions. The PC can hardly be considered properly protected due to the impacts of the above trojan.
Ultimate option implies a total formatting for any drives of your PC. That is not an option for many users, for it destroys all the data hosted by the machine. The best solution to pick would be in-depth system examination with a reliable security suite.
The trojan that has installed Ykcol ransomware , unless removed, is to trigger its installation campaign as soon as a new strain of ransomware is available. Thereby, it is critical to kill it as soon as possible.
The technique successfully overcomes malicious software, including any ransoming threats. It deploys a reputable security suite that offers not a single chance for malicious components to avoid detection and extermination. The software is incredibly user-friendly and operates on a single-click basic.
It is good to note the removal of Ykcol ransomware does not recover the data affected. However, the virus is subject to compulsory extermination or else is going to introduce related infections into the machine.
1. Click the button to download the stub installer and go through several setup dialogs. Once the tool is up and running, click Start Computer Scan
2. Wait until the cleaner checks the PC for Ykcol ransomware malicious code. As soon as the scan is completed, the report will list all malware objects spotted in the system. Make sure the entries for detected infections are checked, and select the Fix Threats feature. This will result in malware removal and system remediation, so you should now be good to go.
Restore the encrypted files
Ykcol encryption is a sophisticated data modification. There is no simple and single solution to cover all the cases. Transferring the ransom as demanded by the crooks is not the way either.Kindly apply the methods outlined below as they have been carefully developed to provide a recovery help for the most severe cases of encrypting assaults.
Data recovery with automatic software
Good news is that the virus actually deals with copies of the files. The originals have been deleted. The removed data still can be restored by virtue of such tools as Data Recovery Pro.
Shadow Volume Copies
As Windows creates backups at given periods of time, a victim is advised to address relevant restore points. Unfortunately, the method cannot apply unless the System Restore had been enabled prior to the invasion. Please also note the recovery returns files as saved before the time associated with the restore point addressed.
- Previous Versions dialog to target individual files
One can open Properties for any file. The menu has a tab called Previous Versions. It indicates versions of a file that have been backed up.
To make use of the feature, right-click an affected file and choose Properties in the drop-down list. Proceed with clicking the above-mentioned tab. You can opt between the Copy or Restore procedures, the former enabling to copy the item into the location specified by the user.
Backups and removing remaining traces of Ykcol virus
Prevention is the best cure. If you stick to making regular reserve copies of your data and store those outside your operating system, the impacts by the ransomware are very limited. However, prior to copying the data from backups into the system hit by Ykcol ransomware, make sure the removal of this virus has completed.
Your manual removal attempts may kill the ransomware in general. In most of the cases, some remnants manage to survive and are still capable of causing a significant damage. Please apply a reliable anti-malware scanner to detect and remove, if applicable, any remaining infections.
