How to remove Lalo ransomware

Lalo ransomware – a dangerous virus that renders all personal files on  a host machine useless

Lalo ransomware is a file-encrypting cyber infection that launches an encryption algorithm and encrypts most of the non-system files on the compromised PC. It has been detected in the middle of April 2020 by a well-known malware researcher Michael Gillespie who shared his findings on Twitter. The researcher revealed that the Lalo virus is a new strain of an infamous DJVU ransomware, which is already known as s sub-variant of STOP ransomware. It is built on the same malicious code as its ancestors, renders RSA cipher to lock files, and demands a $980 ransom payment. The symptom of a Lalo ransomware attack is a .lalo file extension attached to locked files. Besides, a victim is also supplied with a ransom note called _readme.txt.

Criminals are initiating spam attacks to spread a malicious B236.tmp.exe file, which is one of the main malicious executables that the lalo virus is based on. In addition to malicious spam attachments, bad actors may also exploit vulnerable RDPs^[1] to forcibly inject a malicious payload via a remote server. In any case, if the payload is launched, ransomware roots deeply into the OS and runs multiple malicious processes in the background and alters Windows registry entries. Besides, it blocks AV software, removes Windows Volume Shadow copies, and builds a firewall to terminate third-party data recovery tools. 

Upon all background activities are done, Lalo ransomware launches a scanner for non-system files  (more than 100 extensions), including photos, videos, music, documents, database sheets, and similar. The ransomware encryption process is initiated using the RSA-2048 encryption algorithm, which applies a difficult mathematical structure to encode the files and generate diverse IDs and decryption keys for each victim. 

As soon as the encryption process is finished, victims are introduced with a ransom note, which is, as usual for many ransomware, named _readme.txt. That's a really unpleasant message from hackers behind the Lalo virus, which states the fact that the computer is hacked, all personal files encrypted, and the ransom payment is expected. 

ATTENTION!

Don't worry, you can return all your files!
All your files like photos, databases, documents and other important are encrypted with strongest encryption and unique key.
The only method of recovering files is to purchase decrypt tool and unique key for you.
This software will decrypt all your encrypted files.
What guarantees you have?
You can send one of your encrypted file from your PC and we decrypt it for free.
But we can decrypt only 1 file for free. File must not contain valuable information.
You can get and look video overview decrypt tool:

Price of private key and decrypt software is $980.
Discount 50% available if you contact us first 72 hours, that's price for you is $490.
Please note that you'll never restore your data without payment.
Check your e-mail “Spam” or “Junk” folder if you don't get answer more than 6 hours.

To get this software you need write on our e-mail:
helpmanager@mail.ch

Reserve e-mail address to contact us:

At this time, if the victim hasn't yet noticed the malicious changes executed on the system, most probably will get a shock seeing all files with .lalo file extension. Unfortunately, it's not possible to remove the extension in any way manually. One of the options to get files back is to contact bad actors standing behind Lalo ransomware via helpmanager@mail.ch or helpdatarestore@firemail.cc within 72 hours and pay $490 for a personal Lalo decryption software. 

The other method is to boot your PC into Safe Mode immediately and run a full system scan with it to remove Lalo ransomware package. No, the data will not be decrypted this way. However, having in mind that Djvu ransomware has been cracked by a DemonSlay355 virus researcher who shared a STOPdecryptor software. You can try to decrypt files using this tool; though there's no hundred percent guarantee that it will work on Lalo ransomware virus. 

Anyway, keep in mind that tens of professional IT-savvy virus experts are continuously analyzing this virus and can release a free decryption key at any time. Therefore, we do not recommend rushing to pay the ransom, especially having in mind that contact with criminals may lead to scam or a second ransomware attack. Although the ransom note does not specify how the payment has to be done, based on the practice with previous Lalo ransomware variants, it's very likely that crooks will require the payment in Bitcoins. That's the safest way for criminals to remain untrackable. 

Instead of having any contact with criminals, initiate a full Lalo removal and make a copy of files with .lalo extension. Upon virus removal, you will be able to try to recover them using third-party data recovery tools or wait a while for decryption software. As for the future, we strongly recommend you not to keep valuable information without backups. It's always advisable to have copies of files on the cloud storage, remote server or a USB hard drive, which is accessible for you only. 

Criminals exploit users' inexperience and systems' vulnerabilities to spread ransomware widely

While Lalo ransomware is still under investigation, we can only generalize the ways that it can infect computers. However, it's more than clear that the most vulnerable devices that it enters are lacking system updates, are poorly protected, and already infected with malware. 

In many cases, criminals managed to inject ransomware into devices with the help of Trojans – the infections that may operate in the disguise of a seemingly-legitimate executable file. However, Trojans can serve as a backdoor allowing criminals to steal logins and initiate brute-force attacks. 

Malicious emails or spam is yet another perfect medium to spread. Criminals tend to disguise ransomware payloads under .zip or .exe attachments that are supposedly coming from governmental institutions, well-known companies or even friends of a potential victim. To read the attachment the potential victim may be asked to enable Macros. In this case, the Agree button serves as an allowance to launch ransomware payload. 

Software cracks^[3] or keygens are by far the most successful working ransomware distribution technique. These tools are widely used as they serve as a key for launching pains software for free. The vast majority of users are aware of the risk that they take by downloading those cracks from torrent websites or other questionable sources as they have started been used for malware dissemination many years ago. 

Therefore, to keep files save from Lalo virus and similar infections it's not only important to install AV tools, staying away from suspicious websites, unknown downloads, online software updates, and similar content is of equal importance. 

Manual Lalo removal is impossible

Manual Lalo removal is not possible due to the multiplicity of malicious files on the random system's folders. These files are typically chained, i.e. manual removal of .exe files will either be blocked or the file will be automatically restored by another related executable. Therefore, to remove Lalo or any of its previous variants you'll have to use a professional software utility. A full system scan with SpyHunterCombo Cleaner or MalwarebytesMalwarebytes tool in the Safe Mode environment will eliminate the whole ransomware package. 

However, this malicious infection usually compromises Windows registry entries and deletes a multitude of necessary Windows executables. As a consequence, the system may start crashing or even delivering BSODs. Therefore, you should use a professional repair tool capable of fixing ransomware damage. Our recommendation is FortectIntego.
