Those who have already been attacked by this virus can try to use free Dharma decryptor. The latter is the ancestor of Arrow and so that the decryptor might work. Otherwise, you may need to remove and try to recover data using third-party software.

This crypto-malware is capable of corrupting the following file types:

.Png, .psd, .pspimage, .tga, .thm, .tif, .tiff, .yuv, .ai, .eps, .ps, .svg, .indd, .pct, .pdf, .xlr, .xls, .xlsx, .accdb, .db, .dbf, .mdb, .pdb, .sql, .apk, .app, .bat, .cgi, .com, .exe, .gadget, .jar, .pif, .wsf, .dem, .gam, .nes, .rom, .sav, .dwg, .dxf, .gpx, .kml, .kmz, .asp, .aspx, .cer, .cfm, .csr, .css, .htm, .html, .js, .jsp, .php, .rss, .xhtml, .doc, .docx, .log, .msg, .odt, .pages, .rtf, .tex, .txt, .wpd, .wps, .csv, .dat, .ged, .key, .keychain, .pps, .ppt, .pptx, .ini, .prf, .hqx, .mim, .uue, .7z, .cbr, .deb, .gz, .pkg, .rar, .rpm, .sitx, .tar.gz, .zip, .zipx, .bin, .cue, .dmg, .iso, .mdf, .toast, .vcd, .sdf, .tar, .tax2014, .tax2015, .vcf, .xml, .aif, .iff, .m3u, .m4a, .mid, .mp3, .mpa, .wav, .wma, .3g2, .3gp, .asf, .avi, .flv, .m4v, .mov, .mp4, .mpg, .rm, .srt, .swf, .vob, .wmv, .3d, .3dm, .3ds, .max, .obj, .r.bmp, .dds, .gif, .jpg, .crx, .plugin, .fnt, .fon, .otf, .ttf, .cab, .cpl, .cur, .deskthemepack, .dll, .dmp, .drv, .icns, .ico, .lnk, .sys, .cfg.

The complex file extension appended to the files encrypted by cannot be removed manually. The only way to decrypt data is to use a decryptor which can be obtained by contacting cybercriminals via or emails, sending them a personal victim’s ID, and transferring a ransom.

However, falling into partnership with cybercriminals can expose you at risk of money and data loss, while each ransom collected motivates criminals to initiate further attacks. Our recommendation would be to initiate a full removal using Reimage Reimage Cleaner Intego, SpyHunter 5Combo Cleaner, Malwarebytes or another reputable anti-virus as soon as possible.

IMPORTANT: ransomware belongs to the Dharma family of ransomware. The latter has many variants, but many of them have already been cracked down by ransomware researchers. Therefore, after removal of this virus, try to run a free Dharma decryptor to unlock data encrypted by virus. virus drops a ransom note and demands a crypto-malware, which spreads via malspam and targets random users to gain profit by unlocking people's personal files

Malspam campaigns are used for the distribution of Dharma family viruses

This ransomware is an offspring of Arrow, which belongs to the Dharma, ransomware family. Each of them is known for exploiting multiple social engineering campaigns to infect computers all over the world.

Arrow ransomware variants are known for injecting the payload into Microsoft Office documents, PDF, and ZIP files. Infected documents are attached to rogue email messages that are subsequently distributed via spambots.

Usually, it’s not difficult to distinguish spam emails. They impersonate official authorities or well-known companies, which is why many people fall for the trick. However, a close investigation of those emails is sufficient to recognize them as spam. Usually, spam emails are sent from doubtful email addresses. The body text contains grammar/spelling mistakes and an attachment, which requires enabling Macros to be opened.

We’re collaborating with[3] cybersecurity experts who are professionals in ransomware detection and immunization. To protect from ransomware infection, it’s a must to browse the Internet carefully. The following are the tips they shared:

  • Delete all suspicious email messages or report them as spam;
  • Do not open attachments sent by unknown senders;
  • Beware of fake software updates;
  • Do not fall for clicking on ads or news featuring catchy slogans;
  • Make sure to install a reputable anti-virus with real-time protection and regularly update it.
