LoryEstside ransomware removal instructions

What is LoryEstside?

Discovered by Cyber Security, LoryEstside is a new variant of BitPaymer ransomware. Most ransomware-programs are designed to encrypt data and block access to it unless a ransom is paid. LoryEstside adds the ".locked!" extension to every encrypted file. For example, "1.jpg" becomes "1.jpg.locked!". It also generates a text file (ransom message) for each encrypted file. The ".txt" extension must be manually added to the filenames to open the files. For instance, LoryEstside creates a "1.jpg.readme_txt" text file for a file called "1.jpg". To open this file, it must be renamed to "1.jpg.readme_txt.txt", and so on. All of these text files contain an identical ransom demand message.

The ransom messages contain identical information and state that all files were encrypted with a strong (cryptography) algorithm. Any data backups stored on the computer were also encrypted or deleted. Users of affected/infected computers are urged not to restart their systems or rename or delete the encrypted or "readme" files. According to cyber criminals, any of these actions might lead to permanent data loss (files might be lost, making it impossible to recover them). To receive information regarding decryption, LoryEstside victims are encouraged to contact the developers via the loryEstside@protonmail.com email address. This ransom message contains a Bitcoin wallet address, making it clear that the ransom must be paid using this cryptocurrency. Cyber criminals offer free decryption of two random files as a gesture of their honest intentions and 'proof' that they can be trusted. Files for free decryption should have the ".locked" and ".readme_txt" extensions of each file also included. It is possible that LoryEstside's developers will decrypt these files free of charge, however, this does not mean that they can be trusted. Cyber criminals generally provide none of the promised decryption keys/tools. In many cases, ransomware victims pay the ransom and are then scammed. Transferring money (cryptocurrency) to cyber criminals will not deliver any positive outcome. Unfortunately, most ransomware programs are 'uncrackable': developers use cryptographies that generate unique keys and no other tools are capable of decryption. They store these keys on remote severs accessible only by them. If a data backup has been created, we recommend that you use it to restore everything. We strongly advise against contacting these cyber criminals or making any payments.

The number of ransomware-type programs is growing daily, however, most are very similar. Some examples of other infections of this type include PC-FunHACKED!, Paradise .xyz, and Rumba. Generally, they prevent people from accessing their files through encryption, unless a ransom is paid. Common differences between these programs are cryptography algorithms used to encrypt data and cost of decryption tool/key. Unfortunately, most of these infections are impossible to 'crack' unless, in some cases, they are not fully developed or have bugs/flaws that can be exploited to restore data. Therefore, we recommend that you generate regular backups and store them on remote servers or unplugged storage devices. If not, backups might be encrypted together with other data stored on the computer.

How did ransomware infect my computer?

To proliferate ransomware (and other infections), cyber criminals often use spam email campaigns, trojans (malicious programs), fake software updaters, dubious/untrustworthy software download sources, Windows and various other software cracks. Spam campaigns are used to proliferate malware by employing malicious attachments. These are usually presented as Microsoft Office documents, archive files (RAR, ZIP), PDF files, executable files, and so on. Once opened/executed, they download and install malicious programs and infect operating systems. Trojans are computer infections that proliferate other malware to cause chain infections. If a trojan is installed, it probably also caused the LoryEstside infection. Fake software updaters infect systems by downloading malicious software rather than the expected updates, or by exploiting outdated software bugs and flaws. Untrustworthy software download tools such as peer-to-peer networks (torrents, eMule, and other such tools), various third party downloaders, free file hosting, freeware download websites etc., are often used to present malicious executables as legitimate software. Cyber criminals use these channels to trick people into downloading and installing malicious programs manually.

How to protect yourself from ransomware infections?

To avoid computer infections with malicious programs, Take precautions when browsing the web, downloading, installing and updating software. Download software from official and trustworthy sources only, and using direct links. Avoid using third party sources when downloading software - they are often used to proliferate rogue applications. It is important to keep software updated, however, use implemented tools or functions provided by official software developers. Tools such as third party software updaters should not be used. Do not open email attachments without carefully studying them first. Do not open attachments presented in emails that are received from unknown, suspicious addresses. Finally, reputable anti-virus/anti-spyware software can detect and remove threats before they can do any harm. If your computer is already infected with LoryEstside, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.
