Today, I am going to explain you all about Cerber ransomware 3 & 4 version. Every one of us know what a virus or a malware is, don’t we? Antivirus companies are working hard to roll out updates as even a minute security issue arises. But the new villain in the cyber security field is ransomware.
Note: Cerber 3, Cerber 4, Cerber 5 and Cerber 6 version has been released. The previous patch is no more working. We shall update you when we get any new decryptor tool. As of now, there is no decryptor or ransomware removal tool available specifically for cerber ransomware.
Update1: Please follow our updated list of all ransomware decrypt tools released so far.
Most of you are hearing this name for the first time, I know. But you should understand what it is and aware of the healing methods as well because ransomware is a serious issue. And right after the WannaCry Ransomware cyber attack all over the world, it’s pretty serious now. Here I am going to explain about a special type of Cerber ransomware. But there is no point in doing so, given you have no idea what a ransomware is. So, let me tell what it is.
A ransomware is not exactly a malware. It doesn’t damage your computer or make it act weirdly out of the blue. Instead, a ransomware locks special types of files in your computer. And when you try to access them, it will open a wizard that demands money or ransom.
Mostly, they accept money in the form of bitcoins as it allows maximum anonymity in the transaction. The ransomware gives you a specific time limit, beyond which no one can access the files if you don’t give the money. Once you send them payment and enter the correct reference number, your computer will act normally.
Cerber 4.1.6 is a new Ransomware in the cyber world but the latest one is Potato Ransomware & ODIN Ransomware which is latest version of Locky. It has infected hundreds if not thousands of systems all around the world. The algorithm of cerber 4.1.6 is bit different from what we saw in other ransomware. So is your computer or laptop infected with Cerber Ransomware? If yes, then you must know how to remove and decrypt the encrypted files with .cerber 4.1.6 extension. Before you see the Cerber4 decrypt working method, let me explain all about Cerber4! Here you go!
With that being said, let’s move on to the details of Cerber ransomware.
What is Cerber Ransomware?
At first, you must know what Cerber Ransomware is.
Cerber 4.1.6 is a later version of the hazardous ransomware Cerber. The prime action it does is encrypting your important files and documents. (Along with the introduction, you will read the working of Cereber ransomware here as well). There are multiple ways, through which Cerber 4.1.6 can sneak into your system. I will talk about it later.
Once Cerber ransomware gets into the computer, it will create an executable file in your app data folder insider user directory. Then, the executable file will be run to scan the entire drives for the files specified in its algorithm. When the ransomware finds specific types of files, it will start encrypting the same. And, it converts them to files with .cerber4 extension.
You can’t normally open the files encrypted by the ransomware. Say you have a file named ‘work detail.pdf’, Cerber ransomware will transform it to ‘1thY47NB6g.cerber4’. Every time, it generates an alphanumerical file name with ten characters and cerber4 extension. Then, you will see a change in the desktop wallpaper and a ransom demanding message on it (sample is given below).
“Your documents, photos, databases and other important files have been encrypted!
If you understand all importance of the situation then we propose to you to go directly to your personal page where you will receive the complete instructions and guarantees to restore your files.
There is a lost of temporary addresses to go on your personal page below.”
At the end of the message, you will get a few website addresses that will lead you to pages with payment information. Along with this wallpaper change, you will also see three special files on the desktop; # HELP DECRYPT #.html, # HELP DECRYPT #.txt, # HELP DECRYPT #.url. Some old versions of Cerber4 ransomware create files such as @[email protected], @[email protected] and @[email protected].
The first two files (txt and HTML) contain the same ransom demanding message whereas the second one brings you to the payment page. The similar procedure takes place when ransom amount is asked to Decrypt CryptoLocker During the encryption process, it generates a private key for decryption and keeps the same in a remote server owned by the developer of the ransomware. As there are no tools available for automatic decryption, one must need the exact key to get the file access back.
On the payment page, it will demand 0.7154 bitcoin (equals about $410). In case you fail to send the amount within the proposed time limit (mostly five days), the amount will be doubled to 1.4308. But in previous Cerber ransomware versions, the ransoms were higher than this amount. The ransomware developers prefer Tor and Bitcoin currency due to the scope of anonymity it offers.
I recommend you shouldn’t act as per the instructions of the ransomware. The researches proved that the developers often ignore the victims. Suppose, your computer is infected by Cerber ransomware and, you paid the demanded ransom provided the files are of the highest significance. But chances are you will never get the files back to the original state.
Hence, the disinfection methods and restoring are preferred than being a puppet of ransomware developers.

How does Cerber Virus Get into My System?
As I said earlier, there are multiple ways for it. Nevertheless, the most used method is to email.
Mostly, the ransomware developers craft a seem-to-be legitimate email. The widely used strategy is to duplicate the emails sent by a shipping or courier company like FedEx and DHL. It will make you believe that they tried to send you a package and failed. In order to make the shipping deliverable, they say, you have to make sure your details are correct from the following document.
About 90% of people open the attachment even without checking the sender’s email address. There is a conventional thought that only executable files cause security threats. But no! Such document contains inbuilt macros to be run in the background. Once you open the document, you will think that it was a harmless prank mail. Within that time, the ransomware creates a copy of its own in the user directory.
Another method is via freeware and cracks. If you are a person who has a habit of installing cracks of paid software, you need to be careful from this moment. A ransomware can easily be integrated into an executable file. So, brace yourself to face a security threat!
Types of Files Affected by Cerber Ransomware
Cerber ransomware targets many common and uncommon file types. I have collected an extensive list of such file extensions, which you can read below.
“.sql, .mp4, .7z, .rar, .m4a, .wma, .avi, .wmv, .csv, .d3dbsp, .zip, .sie, .sum, .ibank, .t13, .t12, .qdf, .gdb, .tax, .pkpass, .bc6, .bc7, .bkp, .qic, .bkf, .sidn, .sidd, .mddata, .itl, .itdb, .icxs, .hvpl, .hplg, .hkdb, .mdbackup, .syncdb, .gho, .cas, .svg, .map, .wmo, .itm, .sb, .fos, .mov, .vdf, .ztmp, .sis, .sid, .ncf, .menu, .layout, .dmp, .blob, .esm, .vcf, .vtf, .dazip, .fpk, .mlx, .kf, .iwd, .vpk, .tor, .psk, .rim, .w3x, .fsh, .ntl, .arch00, .lvl, .snx, .cfr, .ff, .vpp_pc, .lrf, .m2, .mcmeta, .vfs0, .mpqge, .kdb, .db0, .dba, .rofl, .hkx, .bar, .upk, .das, .iwi, .litemod, .asset, .forge, .ltx, .bsa, .apk, .re4, .sav, .lbf, .slm, .bik, .epk, .rgss3a, .pak, .big, wallet, .wotreplay, .xxx, .desc, .py, .m3u, .flv, .js, .css, .rb, .png, .jpeg, .txt, .p7c, .p7b, .p12, .pfx, .pem, .crt, .cer, .der, .x3f, .srw, .pef, .ptx, .r3d, .rw2, .rwl, .raw, .raf, .orf, .nrw, .mrwref, .mef, .erf, .kdc, .dcr, .cr2, .crw, .bay, .sr2, .srf, .arw, .3fr, .dng, .jpe, .jpg, .cdr, .indd, .ai, .eps, .pdf, .pdd, .psd, .dbf, .mdf, .wb2, .rtf, .wpd, .dxg, .xf, .dwg, .pst, .accdb, .mdb, .pptm, .pptx, .ppt, .xlk, .xlsb, .xlsm, .xlsx, .xls, .wps, .docm, .docx, .doc, .odb, .odc, .odm, .odp, .ods, .odt”

Cerber Removal Tool
I am not giving you a guarantee that the tools I shared here can remove Cerber ransomware. But you have a greater chance in doing so by downloading SpyHunter 4.
Malwarebyte’s Anti-malware for Cerber Removal
Step 1: First, you have to download Malwarebyte’s Anti-malware. What you get is an executable installer file. Just open the same and follow on-screen instructions to install the software. (I recommend doing this after logging into Safemode with networking).
Step 2: Once you finish installing the tool, you should open the interface in case it doesn’t get opened automatically.
Step 3: You will see a Scan Now button on the first screen of the software itself. As Anti-malware gets regular updates, the interface may differ in your case. But the core function remains the same.
Step 4: You have to wait some time to get the scanning finished. The scanning time solely depends on the number of files you have. The greater the number of files, the more the scanning time will be.
When it finishes the scan, you will see the result.
Step 5: There, you will get the option to select the detected malware. Just check all the detected ones and hit Remove selected.
Step 6: In order to release your computer completely from the clutches of malware, you should reboot the system. Apparently, Anti-malware will ask you whether to restart the computer or not. You must choose Yes.
Another effective Cerber ransomware removal tool that I found out is Hitman Pro.
Step 1: Yeah, you have to download Hitman Pro first. Don’t forget to run the downloaded installer to finish installing the software on your computer.
Step 2: There is not even a single complicated step in installing Hitman Pro. Once the installation finishes, it will start scanning your computer for malware.
You must wait some time to get it completed.
Step 3: When the scanning process is completed, you must choose Next on the interface that shows the result.
Step 4: On the next screen, you will be asked to enter the license key. But you can avail a free license valid for 30 days and it is enough to remove the detected malware including the ransomware.
Finally, you need to change the wallpaper and, delete the html, txt and url files on the desktop as well.
