What is Erop Ransomware

Erop is a new ransomware variant derived from the STOP/Djvu family. Malware of such is designed to encrypt users’ data and demand victims to pay money for its decryption. Apart from becoming inaccessible after encryption, the targeted files also get altered visually – by receiving the new .erop extension. To illustrate, a file like 1.pdf will change to 1.pdf.erop and become no longer accessible. Once successful encryption gets to a close, Erop generates a text note called _readme.txt which contains decryption guidelines. This ransom note name is quite generic and has been used by other STOP/Djvu variants as well, only with slight variance in cybercriminals’ contact information.

Inside this note, victims are told it is necessary to purchase specialized decryption software for $980 (or $490 if paid within 72 hours after infection). While establishing e-mail communication with swindlers, victims can also attach 1 encrypted file that contains no valuable information and cybercriminals will decrypt it for free. This way, they will prove their decryption abilities and ostensibly their trustworthiness. The reason we used “ostensibly” here is because some users report getting scammed by many ransomware developers even after paying the ransom. This is why it is not recommended to meet the demands of threat actors and make any transfers to them. Unfortunately, it is necessary to admit that cybercriminals are the only host of private keys used for decryption. This means the only way to get your data fully decrypted is by paying the attackers and in the best case successfully getting the promised software. It may be possible to decrypt files if there are different flaws and bugs or if files were encrypted using “offline” keys (ending with “t1”). Otherwise, in case data exchange with the ransomware’s command server was established correctly and generated an “online” key – full decryption is rarely possible. Opposite to offline keys, online keys are unique for each victim, which is the main reason, making decryption practically impossible without original developers. In this case, you can only attempt to restore part of the file which was encrypted using specialized third-party tools. While some older STOP/Djvu versions can be officially decrypted, Erop Ransomware is relatively new and therefore less likely to fall under this category. As of now, the only ways victims can recover their data are either to pay cybercriminals, recover files from an available backup, or try partial recovery with third-party software. It is worth-mentioning that Erop Ransomware may also block access to some security-related websites and be distributed alongside trojan porgrams (e.g., RedLine, Vidar, Azorult, etc.) that steal personal information. Before trying to restore data without the involvement of cybercriminals, it is essential to remove the infection from your computer – thus, preventing its malicious activity. Read carefully our guide below to do so and explore various recovery alternatives to return your files.

How Erop Ransomware infected your computer

Ransomware infections are often distributed using e-mail spam letters, trojans, deceptive third-party downloads, pirated/cracked downloads, fake software cracking tools, fake software updates/installers, backdoors, keyloggers, botnets, system exploits, and other dubious channels as well. The most typical infection scenario is when inexperienced users get tricked into opening some malicious content (e.g., attachments or links). Quite often ransomware is disguised as some legitimate file (.DOCX, .XLSX, .PDF, .EXE, .ZIP, .RAR, or .JS extensions) and distributed through e-mail letters. Such letters usually imitate names of legal companies/entities (e.g., delivery companies, tax authorities, banks, and so forth). Cybercriminals largely benefit from click-bait titles, which make inexperienced or excessively curious users open malicious attachments or links. As a result, the contained infection deploys its malicious code to get installed onto the targeted system. To prevent such and similar drive-by (stealth) installations of malware, you should avoid downloading software from unofficial resources (Peer-to-Peer websites, torrent pages, landing pages, etc.) and beware of opening content that looks suspicious. Read our guide below and learn how one can protect his PC against threats like ransomware (and other possible malware) in the future.

  7. How to protect from threats like Erop Ransomware

Virus modifies “hosts” file to block Windows updates, downloading antivirus programs, and visiting sites related to security news or offering security solutions. Erop Ransomware comes along with AZORult trojan, which was initially created to steal logins and passwords. The process of infection also looks like installing Windows updates, the malware shows a fake window, that mimics the update process.

fake windows update from Erop Ransomware

It uses rdpclip.exe to replace a legal Windows file and to launch an attack on a computer network. After encrypting the files, the encrypter is deleted using the delself.bat command file. Erop Ransomware virus is propagated via spam attack with malicious e-mail attachments and using manual PC hacking. Can be distributed by hacking through an unprotected RDP configuration, fraudulent downloads, exploits, web injections, fake updates, repackaged, and infected installers. The virus assigns a certain ID to the victims, which is used to name those files and supposedly to send a decryption key. Great tools to protect against Erop Ransomware are: Emsisoft Anti-Malware and Malwarebytes Anti-Malware.
