Cypress Virus Files – How Did I Get It and What Does It Do?
Cypress ransomware is a cryptovirus based on the code of another ransomware called Nitro. Attack campaigns are realized via techniques designed to deliver malicious files on target operating systems. Some of the techniques are malspam, corrupted software installers, torrent files, fake software update notifications, and hacked websites.
Malspam is highly likely to be the main spread channel. Spam email messages attempt to deliver malicious software on computer systems. These emails have a few common traits. They pose as representatives of well-known companies, feature file attachments or show clickable URLs.
The moment Cypress ransomware payload runs on a target system, it initiates a complex attack of a few stages. During the attack, the Cypress virus performs lots of malicious operations that enable it to misuse legitimate system files. It can achieve privilege escalation and set malicious files to execute automatically on every system start. It also becomes able to activate a built-in cipher module to complete a sophisticated data encryption process.
During data encryption stage, Cypress virus scans all system drives for target files and encodes them with a strong cipher algorithm. Among the types of files corrupted by Cypress ransomware may be:
→ .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
Unfortunately, the encryption process restricts the access to corrupted files. Files encrytped by this ransomware can be recognized by the specific suffix .cypress. For example, the file photo.jpg appears as photo.jpg.cypress.
After the completion of all malicious modifications and data corruption, the ransomware creates a ransom message that aims to convince you to pay hackers a ransom fee.
Here is how this ransom message looks like:
We know that you need to restore .cypress files but we strongly advise you to refrain from transferring money to cybercriminals. For the sake of your security, we recommend that you clean malicious files from the infected system, back up encrypted files, and consider the help of alternative data recovery methods.
