Malware Removal Tool
Several popular propagation techniques may be used for the activation of malicious Contact virus files on target operating systems. Among these techniques are malspam, apps with corrupted installers, torrent files, fake software updates, hacked websites, and links to hacked websites posted on social media platforms and other shady sites.
The main distribution technique used by Contact ransomware’s operators is unknown to the cybersecurity community. Still, like a ransomware threat, Contact is likely to be included primarily in malicious spam emails.
Malspam technique or spam emails that deliver malicious code tries to trick people into believing that they see emails sent by legitimate institutions, businesses, or well-known websites in their inboxes. However, the emails contain the nasty ransomware payload and present it like an attached file (.rar, .docx, .xls, .jpg, .PDF, etc.) or a clickable link address or both. The moment the ransomware payload loads on the system, the Contact ransomware infection starts.
To prevent falling victim to malicious emails, we recommend the following:
- Look for spell errors.
- Check the grammar.
- Pay attention to the email address – shoul it be considered as a legitimate or as a suspicious?
- Upload attached files to an online virus scanner like VirusTotal before opening them on your computer.
- Do the same with all links you see.
- Do not rush into following presented requirements.
Contact virus will perform a long sequence of malicious modifications once started on a computer system. It will modify registries, install malicious files and hijack legitimate processes to misuse their functionalities. When it reaches the phase that enables it to activate its built-in cipher module, it scans predefined system drives for commonly used types of files and encrypts all these files with a strong cipher algorithm. Among the files corrupted by Contact virus 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 totally corrupts valuable files. This issue, in turn, limits access to their data. Corrupted files could be recognized by the [random_string].firstname.lastname@example.org sequence of extensions added to their names.
When the ransomware finishes the data corruption process, it drops a ransom message on the system. Then the message may pop up on the screen automatically.
The Contact’s ransom message has the name CONTACT-README-WARNING.html. The goal of this nasty message is to convince you to pay a ransom fee for .contact files to hackers.
