Rabbit ransomware removal guide

What is Rabbit?

Ransomware-type programs generally encrypt data stored on computers, which allows developers (cyber criminals) to blackmail victims by making ransom demands. Rabbit ransomware does not encrypt data but locks the computer screen and displays a ransom demand window. This ransomware-type program was discovered by MalwareHunterTeam.

Rabbit scam

Rabbit disguises itself as a "Windows Driver Update.exe" executable file. Once opened, this file generates a User Account Control window that asks users if they wants to allow this app to make changes to the device. If this permission is given, Rabbit ransomware locks the computer screen and displays a random demand window. It states that Windows has been infected/locked by Rabbit. To unlock it, victims are urged to pay 0.005 Bitcoin or 0.15 Ethereum (these are cryptocurrencies). Rabbit's victims are encouraged to make payment within 24 hours, otherwise all files stored on the computer will be deleted. As 'proof' that payment has been made, Rabbit developers request that victims send a transaction ID to the rabbit.channel@gmail.com email address. Once this is done, they promise to send a password that will supposedly unlock the computer screen. In fact, there is no need to pay. To unlock computers, people can use the "RabbCompany66" password provided by MalwareHunterTeam.

There are many ransomware-type programs, however, unlike Rabbit, they encrypt data using crytpography algorithms (symmetric or asymmetric). Some examples are Robbinhood, Mr-X666, and Doples. Typically, cyber criminals use these programs to encrypt data and make ransom demands. The main differences between them are cryptography algorithm used to encrypt data and cost of a decryption tool or key. Unfortunately, most computer infections of this type use encryptions that cannot be decrypted without the involvement of cyber criminals - only they have a tool capable of decryption. Decryption without using these tools is possible only if these programs are in development, have various bugs/flaws, and so on. To prevent data and possible financial loss, maintain regular backups and store them on remote serves or unplugged storage devices.

How did ransomware infect my computer?

In most cases, computers become infected with ransomware-type programs through spam campaigns, Trojans, fake software updaters, software 'cracking' tools, and dubious software download channels. People who proliferate computer infections of this type use spam campaigns by sending emails with attached malicious files such as Microsoft Office or PDF documents, archives such as ZIP, RAR (and other files of this type), executable (.exe), or JavaScript files. Their main purpose is to trick recipients into opening the attachment, which results in download and installation of a high-risk computer infection. Fake software updaters usually infect computers when they download and install malicious programs rather than expected updates or fixes. These tools can also be used to exploit outdated software bugs/flaws. Trojans are infections that proliferate malware. Therefore, if a computer is infected with a Trojan, it will cause chain infections. Another way to cause ransomware and other infections is through Peer-to-peer (P2P) networks, free file hosting, freeware download and unofficial websites, third party downloaders, and other such tools. Cyber criminals use these channels to trick people into downloading and installing malicious programs. Software 'cracking' tools are programs that supposedly allow users to bypass paid activation of software or operating systems, however, cyber criminals employ them to proliferate computer infections. Rather than activation any software they cause download and installation of high-risk viruses.

How to protect a computer from ransomware infections?

If an email contains an attachment or web link and is sent from an unknown/untrustworthy address, do not open it (at least not without being sure that it is safe to do so). Keep installed software updated, however, this should be done using implemented functions or tools provided by official developers. Do not download software from untrustworthy/unofficial websites, using third party downloaders, Peer-to-Peer networks, or other similar sources. Download from official websites and using direct links. Paid software should be activated properly and not using 'cracking' tools that bypass paid activation. These tools are illegal and often cause computer infections. Finally, have reputable anti-spyware or anti-virus software installed and keep it enabled and updated. These tools can prevent damage from viruses early. If your computer is already infected with ransomware, we recommend running a scan with Spyhunter for Windows to automatically eliminate it.
