Belonging to the Aurora ransomware family, Serpom ransomware is a malicious program. Serpom ransomware operates by encrypting the user’s data on the computer system. Later, it asks for a ransom amount to get the decryption tool to retrieve your files. Also, it renames the compromised files by adding the “.serpom” extension to it.
For instance, if you have a file with the name “Test.jpg,” then it renames it as “Test.jpg.serpom.” Additionally, it also creates three text files with instructions related to the encryption. It also shares the information to get the decryption tool. The text files that it creates on your system have the names “@_FILES_WERE_ENCRYPTED_@.TXT,” “@_HOW_TO_DECRYPT_FILES_@.TXT,” and “@_HOW_TO_PAY_THE_RANSOM_@.TXT.”
All the information provided in the text files is in the Russian language. It informs the user that decryption is possible using an RSA key. RSA is a type of algorithm used to encrypt your data. Also, the text provides a Tor site to perform the transaction of ransom. The user has to input a unique ID on the website that is provided in the document. Further, the site shows user-related information like IP address, size of encrypted data, and the date and time of encryption.
Developers behind the Serpom ransomware demands a ransom of 0.06341203 bitcoins. The bitcoin wallet address is present on the site. Also, the mentions that the user would get the decryption tool and key after the successful payment. Usually, cybercriminals do not provide any decryption tool even after payment. Thus, making you a victim of financial fraud. Therefore, we suggest not to pay the ransom amount to the developers.
One of the best ways to save your data is by having a backup stored in some other device.
This guide was written to help you remove the infection itself from your computer, and if a 100% proven method to recover the encrypted files is found we will update this guide.
We cannot help you recover your files and we can only recommend that you use ShadowExplorer or free file recovery software to restore your documents.

1. How did the Serpom ransomware get on my computer?
The Serpom ransomware is distributed via spam email containing infected attachments or by exploiting vulnerabilities in the operating system and installed software.
Cyber-criminals spam out an email, with forged header information, tricking you into believing that it is from a shipping company like DHL or FedEx. The email tells you that they tried to deliver a package to you, but failed for some reason. Sometimes the emails claim to be notifications of a shipment you have made. Either way, you can’t resist being curious as to what the email is referring to – and open the attached file (or click on a link embedded inside the email). And with that, your computer is infected with the Serpom ransomware.
This ransomware was also observed attacking victims by hacking open Remote Desktop Services (RDP) ports. The attackers scan for the systems running RDP (TCP port 3389) and then attempt to brute force the password for the systems.
2. What is Serpom ransomware?
- Ransomware family: Aurora
- Extensions: .serpom
- Ransom note: @_FILES_WERE_ENCRYPTED_@.TXT
- Ransom: 0.06341203 bitcoins
- Contact: serpom@protonmail.com
This Serpom ransomware variant restricts access to data by encrypting files with the .serpom extension. It then attempts to extort money from victims by asking for “ransom”, in form of Bitcoin cryptocurrency, in exchange for access to data.
This ransomware targets all versions of Windows including Windows 7, Windows 8.1 and Windows 10. Serpom ransomware searches for files with certain file extensions to encrypt. The files it encrypts include important productivity documents and files such as .doc, .docx, .xls, .pdf, among others. When these files are detected, this infection will change the extension to .serpom, so they are no longer able to be opened.
The Serpom ransomware changes the name of each encrypted file to the following format: .serpom.
Files targeted are those commonly found on most PCs today; a list of file extensions for targeted files include:
.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
Once your files are encrypted with the .serpom extension, this ransomware will create the @_FILES_WERE_ENCRYPTED_@.TXT ransom note in each folder that a file has been encrypted and on the Windows desktop.
When the infection has finished scanning your computer it will also delete all of the Shadow Volume Copies that are on the affected computer. It does this so that you cannot use the shadow volume copies to restore your encrypted files.
3. Is my computer infected with Serpom Ransomware?
When Serpom ransomware infects your computer it will scan all the drive letters for targeted file types, encrypt them, and then append the .serpom extension to them. Once these files are encrypted, they will no longer able to be opened by your normal programs. When this ransomware has finished encrypting the victim’s files, it will create a @_FILES_WERE_ENCRYPTED_@.TXT text file which includes instructions on how to recover the files.
Below is the message that you will see in the @_FILES_WERE_ENCRYPTED_@.TXT file:

4. Is it possible to decrypt files encrypted with the Serpom ransomware?
The security companies and government officials often release decryptors for ransomware. You can take help of these decryptors to decrypt your encrypted files by Serpom ransomware.
However, it is not necessary that decryptors are available for kind and type of the ransomware you got infected. Especially if the ransomware is new and widespread, then it is most likly that you won't find decryptors for it. If it is an old and popular ransomware then you might find the decryptors.
The first step towards finding the decryptor is to know the acutal name and type of ransomware you get infected. To do that you can take help of NoMoreRansom.org. Visit the website and paste the ransom note in box provided. You can also upload the encrypted file to know the ransomware name. Once you do that click on GO! FIND OUT button.
Now the website will tell you about the type of ransomware and also provide you link if there is a decryptor available.
ID Ransomware is a similar website, you can upload the ransom note, sample encrypted file, or the contact email address to know about the type of ransomware. Once you know about it you can find the decryptors on the internet. But do not download decryptors from shady websites they may further infect your computer.
However you can trust the decryptors for Serpom ransomware from the below sites.
If you haven't find the decryptors then it is not possible to get your files back. That doesn't mean you should pay ransom to the cybercriminals. Do not pay any money to recover your files. Even if you were to pay the ransom, there is no guarantee that you will regain access to your files.
If you’ve already paid the ransom, immediately contact your bank and your local authorities. If you paid with a credit card, your bank may be able to block the transaction and return your money.
You can also contact the following government fraud and scam reporting websites:
- In the United States, go to the On Guard Online website.
- In Australia, go to the SCAMwatch website.
- In Canada, go to the Canadian Anti-Fraud Centre.
- In France, go to the Agence nationale de la sécurité des systèmes d’information
- In Germany, go to the Bundesamt für Sicherheit in der Informationstechnik website.
- In Ireland, go to the An Garda Síochána website.
- In New Zealand, go to the Consumer Affairs Scams website.
- In the United Kingdom, go to the Action Fraud website.
If your country or region isn’t listed here, we recommend that you contact your country or region’s federal police or communications authority.
