The 'ReCoVeRy+[RANDOM LETTERS] File Extension' Ransomware is a threat that has been very active in February and March of 2016. The 'ReCoVeRy+[RANDOM LETTERS] File Extension' Ransomware is one of the many known variants of the infamous TeslaCrypt ransomware Trojan. This threat has been used to attack computers since 2014. Although PC security researchers had been able to help computer users recover from TeslaCrypt infections, it seems that the 'ReCoVeRy+[RANDOM LETTERS] File Extension' Ransomware and new TeslaCrypt variants are no longer susceptible to the same fix as before. This is because the 'ReCoVeRy+[RANDOM LETTERS] File Extension' Ransomware and other new variants of this threat are the version 3.0 of this threat, which has eliminated the loophole that had allowed the recovery of encrypted files previously. If your files have been encrypted by the 'ReCoVeRy+[RANDOM LETTERS] File Extension' Ransomware, then you will need to restore them from an external backup or obtain the decryption key.
What a Threat Like the 'ReCoVeRy+[RANDOM LETTERS] File Extension' Ransomware may Cause to a Computer User
Ransomware Trojans like the 'ReCoVeRy+[RANDOM LETTERS] File Extension' Ransomware are fairly predictable and designed to assume the control of a computer and encrypt the victim's files, holding them for ransom until the affected computer user pays a large amount using Bitcoin or a similar payment method. PC security analysts have determined that the 'ReCoVeRy+[RANDOM LETTERS] File Extension' Ransomware, like other new variants of TeslaCrypt 3.0, may be spread using corrupted email attachments. As soon as the 'ReCoVeRy+[RANDOM LETTERS] File Extension' Ransomware enters a computer, it searches the user's computer for files that match file extensions in its configuration file. The 'ReCoVeRy+[RANDOM LETTERS] File Extension' Ransomware encrypts the following types of files (with new extensions being added to this list in new updates to this threat):
.7z; .rar; .m4a; .wma; .avi; .wmv; .csv; .d3dbsp; .sc2save; .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; .mcgame; .vdf; .ztmp; .sis; .sid; .ncf; .menu; .layout; .dmp; .blob; .esm; .001; .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; .DayZProfile; .rofl; .hkx; .bar; .upk; .das; .iwi; .litemod; .asset; .forge; .ltx; .bsa; .apk; .re4; .sav; .lbf; .slm; .bik; .epk; .rgss3a; .pak; .big; .unity3d; .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; .jpeg; .jpg; .cdr; .indd; .ai; .eps; .pdf; .pdd; .psd; .dbfv; .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.
The 'ReCoVeRy+[RANDOM LETTERS] File Extension' Ransomware will take all files with the above extension and use an AES encryption algorithm to make them inaccessible. As part of its attack, the 'ReCoVeRy+[RANDOM LETTERS] File Extension' Ransomware will change the files' extension to ReCoVeRy and a string of random letters. The 'ReCoVeRy+[RANDOM LETTERS] File Extension' Ransomware also drops ransom notes in the form of text, image, or HTML files in directories where it has encrypted the victim's files. These ransom notes tell the computer user to pay a large amount of money in BitCoin to recover the encrypted files.
Recovering from the 'ReCoVeRy+[RANDOM LETTERS] File Extension' Ransomware
PC security researchers strongly advise that computer users abstain from paying the 'ReCoVeRy+[RANDOM LETTERS] File Extension' Ransomware ransomware since there is no guarantee that the people responsible for this attack will restore the encrypted files once the amount is paid. Paying this ransom further finances these attacks, allowing the 'ReCoVeRy+[RANDOM LETTERS] File Extension' Ransomware to go on to infect additional computers. Instead, computer users should make sure that all files are properly backed up in an external device or location.

Digital Signatures
Digital Signatures
This section lists digital signatures that are attached to samples within this family. When analyzing and verifying digital signatures, it is important to confirm that the signature’s root authority is a well-known and trustworthy entity and that the status of the signature is good. Malware is often signed with non-trustworthy “Self Signed” digital signatures (which can be easily created by a malware author with no verification). Malware may also be signed by legitimate signatures that have an invalid status, and by signatures from questionable root authorities with fake or misleading “Signer” names.| Signer | Root | Status |

Similar Families
Similar Families
This section lists other families that share similarities with this family, based on EnigmaSoft’s analysis. Many malware families are created from the same malware toolkits and use the same packing and encryption techniques but uniquely extend functionality. Similar families may also share source code, attributes, icons, subcomponents, compromised and/or invalid digital signatures, and network characteristics. Researchers leverage these similarities to rapidly and effectively triage file samples and extend malware detection rules.- Agent.DFD
