.Lesli keeps your files hostage

Ransomware is one of the most popular online threats one can encounter. Every new variation of this malware comes updated and more sophisticated than any other before. This is the case with .Lesli – a cryptovirus that keeps hostage of the data found on the infected computer by encrypting it with a strong and complex algorithm of symbols. Once locked, the data becomes impossible to access without a unique decryption key, which is in the hands of the criminals behind the ransomware. They usually require a huge amount of money in ransom (usually in Bitcoins) for this key, which actually lies in the core of their criminal “business model”. What turns this nasty criminal model even more appealing and popular among the cyber criminal circles is the possibility of the hackers to remain undetected and the huge profit they can make from victims, who pay. The Bitcoin payment method is what helps them hide their traces from the authorities, as this is a special online cryptocurrency, which is very difficult to track.

Where are the places where ransomware mostly spreads?

The methods of distribution that hackers use to spread threats like .Lesli may vary. Usually, they pack a harmful payload inside a Trojan horse installer or Exploit kit, which infiltrates the system for vulnerabilities and inserts the ransomware inside the PC through them. You can come across such threats if you click on spam emails, open suspicious attachments, click on pop-ups and misleading links, land on a malicious website or download a torrent or application. That’s why a common understanding of online safety really comes in handy when you bump into sketchy content and we strongly advise you to avoid interacting with or even clicking on it. The bad thing about these infections is they are really hard to detect. They mostly have no visible symptoms until the malicious encryption is completed and a ransom note appears on the screen, informing the victim of the harmful results. In fact, the hackers would do their best to clearly notify you about the infection that has taken place in various ways. You may find a ransom note directly on your screen as a background picture, in every encrypted folder, on your desktop or even as a vocal message. The main goal is, of course, to get you panicked and make you pay as soon as possible.

What should you do when the infection has taken place?

Losing access to your important data is, with no doubt, a really bad feeling. However, getting impulsive and stressed surely won’t help you handle the situation. Being a victim of ransomware, don’t forget you are dealing with unscrupulous cyber criminals, who would do their best to get some money out of you. They may threaten you, they may give you a short deadline for the payment, they may pretend to be the authorities and make up stories, or even take over your infected machine and insert other viruses in it. All this is a form of emotional attack, the sole aim of which is to make you act impulsively.

However, any security specialist would advise you that this is the worst you could do. Just take your time to think sober and search for other solutions that may be available online. Ask yourself, can you really trust these criminals to really send you the decryption key? And what is the likelihood of them fooling you and leaving your data locked? There are many tricked victims who fall in that trap of paying and then never hear from the crooks again. What if you happen to be the next one? Luckily, you have an option – try the steps in the removal guide below. It will help you remove the infection from your system and regain control over your computer. You can even try to restore some of your data for free if you follow the tips we have suggested below. Want to give it a try?
