LambdaLocker virus is finally defeated – decrypt your files now
LambdaLocker is a virus written in Python that functions as a file-encrypting tool. Cybercriminals use to extort computer users. The latest version presents the ransom demand in UNLOCK_guiDE.tXT file. Interestingly, the author of this malware seems to be a fan of American band rock band as it appends .MyChemicalRomance4EVER file extension and presents atlantis.cf@yandex.com email address for the contact purposes.
The malware authors are quite greedy as they demand 6000 and 700 yuan ($1040) in exchange of the data.
The first versions of Lambda Locker have been detected on January 2017, but after half a year, the developers attempt to revive the threat again. Speaking of the original version, it functions as an ordinary crypto-malware targeting Windows OS[1] and employing AES-256 encryption method to block the most valuable cyber possessions – personal data. In particular, such viruses infiltrate computers by stealth and encrypt files with asymmetrical AES and RSA algorithms [2].
This variation specifically targeted Chinese-speaking countries[3]. In the ransom note, READ_IT.hTmL, the perpetrators demand 0.5 bitcoins which at the amount amounts to $1352.40. This version marks the files with .lambda_l0cked file extension. The virus suggests writing to lambdasquad.hl@yandex.com after paying the ransom.
The data decryption key is stored on a remote server, where the victims would not be able to reach it and use it to decrypt their files. Then comes the time for the LambdaLock creators to offer their solution to the problem. The victim is offered to redeem the files by transferring some Bitcoins to an indicated Bitcoin wallet address [4]. Frankly, the victims are proposed to pay for what is already theirs. That’s what earns this parasite a name of a ransomware virus.
If you are ever in a situation where you are being coaxed into collaborating with anonymous hackers, or more importantly, sending them money for questionable tools, do not lose your cool and remove LambdaLocker from your computer. FortectIntego or MalwarebytesMalwarebytes will be of assistance in this process.
Of course, you should keep in mind that this will not help recover the files but merely delete the virus and its components from the computer. Nevertheless, when the virus is fully eliminated from the computer, you can then employ alternative data recovery techniques to restore some of your important files without a risk of losing your money.

Like most viruses of the kind, Lambda Locker crypto-ransomware has specific features that make it unique and help us to differentiate it from other ransomware. For instance, from the .lambda_l0cked extension that it appends to the infected files you can already tell what kind of virus has infected your computer and start taking certain steps towards its removal.
Besides, you will also notice the READ_IT.hTmL file that will be added to your desktop and every other computer folder that contains encrypted documents. This file is a ransom note which will try to convince users to pay the 0.5 Bitcoin ransom for the data decryption. It is interesting that the note is written in English and Chinese, so we can presume that the ransomware is specifically targeted toward English and Chinese-speaking countries.
Nevertheless, that does not limit the parasite from spreading to other parts of the world. So, no matter where you live, you might one day find that your pictures, audio/video files, Office documents, and archives have been encrypted and that you are in need of a good LambdaLocker removal advice. In such a case, we suggest continue reading the article and learn more about the virus extermination techniques.
Good news: Victims of Lambda Locker ransomware can now recover their files for free. Avast has created an efficient data decryption tool that works on files with .MyChemicalRomance4EVER file extensions. Please follow the instructions we provided (you can find them below the virus removal guide) and restore your files without paying a cent.
New ransomware versions spotted
.MyChemicalRomance4EVER file extension virus seems to be programmed in Python programming language. The ransom message is fully provided in Chinese. In comparison with the original version, the developers are quite greedy they demand 6000 ($885) yuan in exchange for the files. In case a victim fails to transfer the files within the specified amount of time, the amount will increase up to 1000 dollars.
In case affected users encounter any difficulties, they should contact the perpetrators via atlantis.cf@yandex.com. They also provide instructions how to purchase bitcoins. Luckily, there is no need to comply with the demands as the malware is decryptable.[5]
The virtual threat is detected as W32/Trojan.QNSF-9385 or Generic.Ransom.LambdaLocker.7965CD21 (B). It might disguise under VortexVPN.vir.DNvir file. Be vigilant while you are downloading new applications. Do not install programs which are released by “unknown” publishers.
Distribution tricks that help the virus proliferate
We have already mentioned that LambdaLocker is a typical ransomware example and what we mean that it all respects, including its distribution as well. This means that the virus may spread via exploit kits, fake software updates or bundled inside software packages.
Besides, the virus may also be delivered to your email inbox by the malicious spam campaigns [6]. That is why we suggest being careful with the emails you open and the attachments you download to your computer. You never know whether Lambda Locker is not hidden under some legitimate-looking flight confirmation, speeding ticket or even a simple picture [7].
Remove LambdaLocker like a professional
When talking about LambdaLocker removal, we should point out that it is not an easy task. Ransomware viruses are usually designed to fight back and try to stay on the infected computers by all means possible. Thus, even automatic malware elimination tools might sometimes find it complicated to tackle the viruses properly, not to mention manual removal.
One of the major obstacles that anti-ransomware programs face is the blocking of the system scan. When the antivirus cannot scan the system, it cannot locate files of the parasite. Thus, it cannot remove LambdaLocker virus from the computer. Below you will find guidelines that explain how this problem can be overcome. Reboot the system into Safe Mode to get rid of the infection.
