RSA2048Pro ransomware removal instructions

What is RSA2048Pro?

First discovered by MalwareHunterTeam, RSA2048Pro is a ransomware-type virus programmed in C#. Immediately after infiltration, RSA2048Pro encrypts most stored data and adds the ".aes" appendix to the name of each compromised file. Furthermore, RSA2048Pro prioritizes files that are less than three months old. Once files are encrypted, using them becomes impossible. Following successful encryption, RSA2048Pro generates a text file ("Instruction.txt") and places a copy in every existing folder.

The new text file contains a short message stating that files are encrypted and encourages users to contact RSA2048Pro's developers if they wish to restore their data. It is currently unknown whether RSA2048Pro uses symmetric or asymmetric cryptography (the malware name contains RSA letters, yet the extension is ".aes", and so this is probably an RSA or AES algorithm). In any case, decryption requires a unique key generated individually for each victim. Unfortunately, cyber criminals store these keys on a remote server and victims are encouraged to purchase a key to restore data. The cost is currently unknown, since we have not tried to contact RSA2048Pro's developers, however, these demands typically fluctuate between $500 and $1500 in a type of cryptocurrency. No matter what the cost, do not be persuaded to pay. Ransomware developers often ignore victims after payments are submitted. Therefore, paying typically gives no positive result and users are simply scammed. Never contact these people and certainly do not submit any payments. There are currently no tools capable of restoring files encrypted by RSA2048Pro free of charge. Therefore, the only solution is to restore everything from a backup.

RSA2048Pro is regular ransomware, and thus shares many similarities with ScorpionLocker, Gedantar, WhiteRose, My Decryptor, and dozens of others. Note that although these viruses are developed by different cyber criminals, their behavior is identical. All encrypt stored files and make ransom demands. The type of encryption algorithm and size of ransom are the only major differences. Research shows that, unfortunately, most of these viruses employ algorithms that generate unique decryption keys. Therefore, file decryption manually without involvement of developers (contacting these people is not recommended) is mostly impossible. The only possible scenarios are ransomware not being fully developed or having certain bugs/flaws (e.g., the key is hard-coded, stored locally or similar). Ransomware-type viruses present a strong case for maintaining regular data backups, however, users must keep backup files on a remote server (e.g., Cloud) or an unplugged external drive. If not, backups are encrypted as with regular files.

How did ransomware infect my computer?

Ransomware is typically distributed using spam emails (infectious attachments), unofficial software download sources (peer-to-peer [P2P] networks, free file hosting sites, freeware download websites, etc.), fake software update tools, and trojans. Malicious attachments typically come in the format of JavaScript files or MS Office documents. Once opened, these files execute scripts designed to download and install malware. Third party download sources present malware as legitimate software, thereby tricking users into downloading and installing viruses. Fake software updaters infect the system by exploiting outdated software bugs/flaws or merely downloading and installing malware rather than updates. Trojans are the simplest of all - they open "backdoors" for other viruses to infiltrate the system.

Threat Summary:

How to protect yourself from ransomware infections?

The main reasons for computer infections are poor knowledge and careless behavior. The key to safety is caution. Therefore, pay close attention when browsing the Internet. Never open any email attachments that seem irrelevant or have been sent from an unrecognizable/suspicious addresses. These emails should be deleted immediately, without reading. Furthermore, download your apps from official sources only, using direct download links. Third party downloaders/installers often include rogue programs, and thus these tools should not be used. Keep installed applications up-to-date and have a legitimate anti-virus/anti-spyware installed and running. Bear in mind, however, that criminals use fake updaters to proliferate malware. Therefore, update applications using implemented functions or tools provided by the official developer only.
