Red Cerber ransomware / virus (Removal Guide) - Mar 2017 update

Red Cerber virus Removal Guide

What is Red Cerber ransomware virus?

Red Cerber continues following the steps of its predecessor

Red Cerber virus is the latest sample of notorious Cerber ransomware which wreaked havoc throughout the entire year of 2016 and continues doing the same in 2017. The developers of this destructive crypto-malware have managed to release already five versions of this cyber menace.[1] Cerber 5.0.1 and Red Cerber ransomware are the latest versions. All of them are distinctive for certain characteristics, but all of them have been using almost identical ransom notes. The older variations had a tendency to delete shadow volume copies which shattered the last hope of data retrieval for users who did not back up their data. The latest version has some modifications. One of them – it does not delete shadow volume copies of the target files. In addition, this ransomware modifies some part of important system files right after the infiltration. These files include: msxml3.dll.Instructions, KERNELBASE.dll.mui, rsaenh.dll, WScript.exe, WScript.exe.mui, sortdefault.nls, wshom.ocx, etc. The ransom note is usually written in the red background rather than a green one. The extension which was added by the latest versions of Red Cerber ransomware is .ba99. If your file extensions were changed to this extension, you are, unfortunately, infected. Do not panic and concentrate on Red Cerber removal. For that you can use ReimageIntego.

Taking a look back at the evolution story of Cerber, few might remember reports about the malware which targeted only specific countries. The original version contained flaws which limited Cerber’s capabilities. It needed to reboot a computer in order to paralyze it completely. However, it did not take long for the crooks to evolve the threat at lightning speed. They looked for various channels and techniques to boost up the traffic of the destructive infection. It even exploited browser vulnerabilities to infect computers[2]. The more recent version bombarded users with fake credit card emails.

In comparison with other threats, the key change in Red Cerber malware is the disabled command to delete shadow volume copies[3]. These are the copies which grant the chance to restore the lost files after a system crash or another unexpected data loss. Despite this ray of hope, Cerber still poses a decryption challenge for virus researchers. Since the appearance of the original version, IT experts have been able to devise a decryption software for the original version, but the latter versions remain undecryptable. Furthermore, Red Cerber ransomware contains a programmed preference to encode specific folders and files. The gearheads changed the number of encryptable extensions by excluding the following extensions: .bat, .cmd, .com, .cpl, .exe, .hta, .msc, .msi, .msp, .pif, .scf, .scr, and .sys. Though the virus retained a preference for .doc files, it added additional file formats to the list of overall 493 encryptable file extensions. In short, you should hurry up to remove Red Cerber.

How is the virtual infection spread?

The gearheads have been discovering new ways of infecting as many users as possible. Spam emails account for the biggest share of Red Cerber hijack cases. Usually, it comes as a fake report about the payment or billing warning from an ordinary email address which is supposedly sent from a female dresser. It does not require any specific features to spot mismatching and obvious mistakes. First of all, typos and spelling mistakes are a prevalent feature of ransomware spam emails [4]. What is more, the supposed addresser mismatches the credentials provided in the very message content. Furthermore, the cyber infection is spread via the help of exploit kits, specifically RIG and Nemucod[5]. They might be encountered in corrupted websites, such as illegal file-sharing web pages. Note that Flash Player keeps being exploited by ransomware gearheads and Red Cerber developers did not miss the opportunity to use it as well.

Is it hard to remove Red Cerber?

If you are willing to fully exterminate Red Cerber virus, install an anti-spyware application such as ReimageIntego or Malwarebytes. Do not forget to update them before initiating the eradication process. It is possible that the malware might cause some Red Cerber removal problems. Here is when the following instructions come in handy. Note that only after you fully remove Red Cerber, data decryption might be performed.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove Red Cerber from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by 2-spyware.com security experts.

If your files are encrypted by Red Cerber, you can use several methods to restore them:

Using Data Recovery Pro program

Though the best way to decrypt the files would be to obtain the private key, you will not lose anything if you give this software a try.

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by Red Cerber ransomware;
  • Restore them.

ShadowExplorer– the only chance to recover the files?

Shadow volume copies remain one of the key ways to recover the lost or damaged files. Certainly, if they are not eliminated beforehand. Taking into account the fact, that the latter version is disabled from wiping these copies, you might have a chance to get the files back.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Red Cerber and other ransomwares, use a reputable anti-spyware, such as ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes

How to prevent from getting ransomware

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
