What is Bear?

Discovered by Jakub Kroustek, the Bear virus is a new variant of Dharma ransomware-type infections. Like most infections of this type, Bear is designed to encrypt files and make them unusable until the ransom is paid. It renames each encrypted file by adding the ".Bear" extension and including an ID and email address. For example, "1.jpg" might become "[].Bear". It also creates a ransom demand message within the "FILES ENCRYPTED.txt" text file and a pop-up window.

The message within "FILES ENCRYPTED.txt" simply states that all data has been locked, and to decrypt files, ransomware victims must contact Bear developers using the or email addresses. The message within the pop-up window informs Bear victims that files have been encrypted due to a 'security problem' with the computer. An ID is also provided that must be used when contacting criminals. According to Bear developers, the cost (size of ransom) depends on how quickly they are contacted, and the decryption tool is provided only when the ransom is paid. These cyber criminals also offer 'free decryption' of one file as a gesture that they can be trusted. They urge people not to attempt to decrypt files using third party software - according to them, such attempts might result in permanent data loss or increased cost of decryption. Note that cyber criminals cannot be trusted and provide no decryption tools or keys, even if ransom demands are met. In summary, people are scammed. Unfortunately, there are currently no tools capable of decrypting files encrypted by Bear. It is not even known whether files are encrypted using a symmetric or asymmetric cryptography algorithm. Typically, a unique decryption key is generated for each victim, all keys are stored on a remote server controlled by cyber criminals. The best possible (free) solution is to retrieve files using an existing backup.

Other ransomware infections similar to Bear include DataWait, BlackHat and Epoblockl. These are just some examples from many ransomware-type viruses available. Typically, all ransomware infections are very similar and share the same purpose: to encrypt files and to demand payments in return for decryption tools/keys. Common differences between these viruses are ransom amount and cryptography algorithm used for encryption. In most cases, ransomware-type infections are uncrackable and victims are encouraged to contact cyber criminals. File recovery is possible only if a virus is not fully developed or contains bugs/flaws. To prevent data loss, we recommend that you maintain regular backups and store them on remote servers or unplugged storage devices.

How did ransomware infect my computer?

It is difficult to determine exactly how cyber criminals proliferate the Bear virus, however, cyber criminals often proliferate these infections using spam email campaigns, trojans, untrustworthy software download sources, and fake software updaters. Spam email campaigns spread viruses through malicious email attachments (usually, Microsoft Office documents, PDF files, archive files, executables, and so on). The main purpose of these campaigns is to trick people into opening the attachments, which then allow download and installation of viruses. Trojans are malicious programs that proliferate other viruses, thus causing chain infections. Free file hosting and freeware download websites, various peer-to-peer networks (torrent clients, eMule, etc.), and other third party software download sources are often used by cyber criminals who present malicious files (executables) as legitimate. In these cases, they trick people into downloading and installing infections. Fake software updaters often download viruses rather than the updates or exploit outdated software bugs/flaws.

Threat Summary:

Threat TypeRansomware, Crypto Virus, Files locker
SymptomsCan't open files stored on your computer, previously functional files now have a different extension, for example my.docx.locked. A ransom demanding message is displayed on your desktop. Cyber criminals are asking to pay a ransom (usually in bitcoins) to unlock your files.
Distribution methodsInfected email attachments (macros), torrent websites, malicious ads.
DamageAll files are encrypted and cannot be opened without paying a ransom. Additional password stealing trojans and malware infections can be installed together with a ransomware infection.

To eliminate Bear virus our malware researchers recommend scanning your computer with Spyhunter.

How to protect yourself from ransomware infections?

The key to computer safety is caution. Therefore, browse the web, and download, install and update software with care. Do not open attachments or links that are presented in emails sent from unknown/unidentified addresses. If the email seem irrelevant, ignore it. Do not use third party downloaders, installers or other similar software. Research shows that these tools are often used to proliferate rogue applications or other unwanted software. We strongly recommend that you use official tools and functions to update installed software. Other sources might lead to inadvertent installation of unwanted software or even high-risk viruses. Have anti-virus/anti-spyware software installed (and active) - this can prevent computer infection. If your computer is already infected with Bear, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.
