What is BugWare?

BugWare is a ransomware-type virus discovered by MalwareHunterTeam. Once infiltrated, BugWare encrypts stored data using AES-256 cryptography. During encryption, BugWare appends file names with an extension (depending on the BugWare variant): ".[SLAVIC@SECMAIL.PRO].BUGWARE" (first variant), ".[SLAVIC@SECMAIL.PRO].CRIPTOGRAFADO" (second variant) or ".[MAXVISION@SECMAIL.PRO].CRIPTOGRAFADO" (third variant). Following successful encryption, BugWare opens a pop-up window (containing a ransom-demand message) and creates an image file ("wpp.bmp"), placing it on the desktop and also setting it as the desktop wallpaper.

BugWare is Brazilian-based ransomware. The ransom-demand message is in Portuguese and states that files are encrypted using AES cryptography. This encryption algorithm is symmetric and, thus, a single key (used to encrypt and decrypt data) is generated uniquely for each victim. Despite this, the message also states that the generated key is also encrypted using RSA-2048 - an asymmetric encryption algorithm (in which the encryption and decryption keys are different). Criminals store these keys on a remote server. To receive them and restore encrypted data, victims are encouraged to pay a ransom of the equivalent of 1000 Brazilian Real (~$315) in Bitcoins. It is also stated that payment must be submitted within the given time frame (a pop-up contains a countdown timer). The first BugWare variant gives 72 hours, and the second, 168 hours. If the ransom is not paid within one of these time frames, files are (supposedly) deleted permanently. Bear in mind, however, that cyber criminals cannot be trusted. Research shows that these people often ignore victims once payments are submitted. Therefore, there is a high probability that paying will not deliver any positive result (and you will be scammed). Paying is equivalent to sending money to cyber criminals - you will support their malicious businesses. Therefore, we strongly advise you to ignore all requests to contact these people or pay any ransom. Unfortunately, there are no tools capable of cracking the aforementioned encryption algorithms and restoring files compromised by BugWare. The only solution is to restore your files/system from a backup.

BugWare is virtually identical to BTCWare PayDay, ANONCRACK, Asasin, and dozens of other ransomware-type viruses. Although these viruses are designed by different cyber criminals, they have identical behavior - they encrypt files and make ransom demands. The only major differences between ransomware-type viruses are size of ransom (which usually fluctuates between $500 and $1500) and type of encryption algorithm used. Research shows that, unfortunately, most ransomware employs algorithms that generate unique decryption keys. Therefore, unless the malware is not fully developed or has certain bugs/flaws (for example, stores keys locally), file decryption without involvement of developers is impossible (contacting these people is not recommended). For these reasons, ransomware-type viruses such as BugWare present a strong case for maintaining regular data backups.

How did ransomware infect my computer?

Ransomware-type viruses are proliferated in various ways, however, the five most popular are: 1) spam emails; 2) third party software distribution sources; 3) peer-to-peer [P2P] networks; 4) fake software update tools, and; 5) trojans. Spam emails often contain malicious attachments (such as MS Office documents with macros, JavaScript files, etc.) that, once opened, download and install malware. Furthermore, unofficial software download sources (freeware download websites, free file hosting websites, etc.) and P2P networks (torrents, eMule, etc.) proliferate malicious executables that are presented as legitimate software. In this way, criminals often trick users into downloading and running malware. Fake software updaters exploit outdated software bugs/flaws to infect the system. Trojans are the simplest ones - they open "backdoors" for other malware to infiltrate.

How to protect yourself from ransomware infections?

The main reasons for computer infections are lack of knowledge and careless behavior. Be very cautious when browsing the Internet. Never open files attached to emails and received from suspicious addresses - these emails should be deleted without reading. Furthermore, download your software from official sources only and, preferably, using a direct download URL (third party download/installation tools often stealthily install malicious apps). Keep installed software updated and use a legitimate anti-virus/anti-spyware suite. Bear in mind, however, that criminals proliferate ransomware via fake updaters. Therefore, updating software via third party tools is very risky. The key to computer safety is caution.

1. During your computer start process, press the F8 key on your keyboard multiple times until the Windows Advanced Options menu appears, and then select Safe Mode with Command Prompt from the list and press ENTER.

Boot your computer in Safe Mode with Command Prompt

2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.

system restore using command prompt type cd restore

3. Next, type this line: rstrui.exe and press ENTER.

system restore using command prompt rstrui.exe

4. In the opened window, click "Next".

restore system files and settings

5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the BugWare ransomware virus infiltrating your PC).

select a restore point

6. In the opened window, click "Yes".

run system restore

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining BugWare ransomware files.

To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of BugWare are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.

To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.

Restoring files encrypted by CryptoDefense

If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.

To regain control of the files encrypted by BugWare, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.
