1. How did the Crypted_files@qq.com Aqva ransomware get on my computer?

The Crypted_files@qq.com Aqva 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 Crypted_files@qq.com Aqva ransomware.

Dharma 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 Crypted_files@qq.com Aqva ransomware?

• Ransomware family: Dharma Ransomware
• Added Extensions: [crypted_files@qq.com].aqva
• Ransomware note: FILES ENCRYPTED.txt
• Ransom: From $500 to $1500 (in Bitcoins)
• Contact: crypted_files@qq.com

The Crypted_files@qq.com Aqva ransomware restricts access to data by encrypting files. It then attempts to extort money from victims by asking for “ransom”, in form of Bitcoin cryptocurrency, in exchange for access to data.

The Crypted_files@qq.com Aqva ransomware targets all versions of Windows including Windows 7, Windows 8.1 and Windows 10. When the Crypted_files@qq.com Aqva ransomware is first installed on your computer it will create a random named executable in the %AppData% or %LocalAppData% folder. This executable will be launched and begin to scan all the drive letters on your computer for data files to encrypt.

Crypted_files@qq.com Aqva 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 [crypted_files@qq.com].aqva, so they are no longer able to be opened.
Dharma ransomware changes the name of each encrypted file to the following format: [crypted_files@qq.com].aqva.

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 [crypted_files@qq.com].aqva extension, the Crypted_files@qq.com Aqva ransomware will create the FILES ENCRYPTED.txt file 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 Crypted_files@qq.com Aqva Ransomware?

When Dharma ransomware infects your computer it will scan all the drive letters for targeted file types, encrypt them, and then append the Crypted_files@qq.com Aqva 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 pop-up ransom note which includes instructions how you can make a payment.

The messages displayed by this ransomware infection can be localized depending on the user’s location, with text written in the appropriate language.

This is the message that the Crypted_files@qq.com pop-up window will display:

4. Is it possible to decrypt files encrypted with the Crypted_files@qq.com Aqva ransomware?

No, at this time it’s not possible to recover the files encrypted by the Crypted_files@qq.com Aqva malware.
Unfortunately, once the Crypted_files@qq.com Aqva encryption of the data is complete, decryption is not feasible without paying the ransom.
Because the needed private key to unlock the encrypted file is only available through the cyber criminals, victims may be tempted to purchase it and pay the exorbitant fee. However, doing so may encourage these bad guys to continue and even expand their operations. We strongly suggest that you do not send any money to these cyber criminals, and instead address to the law enforcement agency in your country to report this attack.

This page is a comprehensive guide, which will remove the Crypted_files@qq.com Aqva infection from your computer, however we cannot guarantee that your personal files will be recovered. We cannot be held responsible for losing the documents during this removal process.
Malwarebytes and HitmanPro can detect and remove this infection, but these programs cannot recover your encrypted files.

STEP 1: Use Malwarebytes to remove Crypted_files@qq.com Aqva ransomware

Malwarebytes is one of the most popular and most used anti-malware software for Windows, and for good reasons. It is able to destroy many types of malware that other software tends to miss, without costing you absolutely nothing. When it comes to cleaning up an infected device, Malwarebytes has always been free and we recommend it as an essential tool in the fight against malware.

The first time you install Malwarebytes, you’re given a free 14-day trial of the premium edition, which includes preventative tools like real-time scanning and specific protection from ransomware. After two weeks, it automatically reverts to the basic free version that will detect and clean up malware infections only when you run a scan. It is important to note that Malwarebytes will run alongside antivirus software without conflicts.

1. Download Malwarebytes.

   You can download Malwarebytes by clicking the link below.

   When the scan has completed, you will be presented with a screen showing the malware infections that Malwarebytes has detected. To remove the malicious programs that Malwarebytes has found, click on the “Quarantine Selected” button.

If it finds a suspicious file that’s not already known, HitmanPro sends it to their clouds to be scanned by two of the best antivirus engines today, which are Bitdefender and Kaspersky.

Although HitmanPro is shareware and costs $24.95 for 1 year on 1 PC, there is actually no limit in scanning. The limitation only kicks in when there is a need to remove or quarantine detected malware by HitmanPro on your system and by then, you can activate the one time 30 day trial to enable the clean up.

   You may be presented with an User Account Control pop-up asking if you want to allow HitmanPro to make changes to your device. If this happens, you should click “Yes” to continue with the installation.
