Blammo@cock.li ransomware (Removal Guide) - Mar 2018 update

What is Blammo@cock.li ransomware?

Blammo@cock.li is a newest version of Arrow ransomware

Blammo@cock.li is a crypto-ransomware^[1] virus closely related to Arrow ransomware and Dharma. It was detected in the beginning of 2018, spreading via malicious spam email attachments. The executed ransomware payload runs scripts via elevated Command Prompt and injects infected Registry entries. Following system’s modifications, the Blammo@cock.li starts data encryption using AES cryptography^[2] and renders all personal files inaccessible. Each locked file gets one of the following file extensions:

.id-{id}.[bitcoin888@cock.li].arrow
.id-{id}.[Blammo@cock.li].arrow
.id-{id}.[marat20@cock.li].arrow
.id-{id}.[vauvau@cock.li].arrow

Most of these days ransomware-type viruses remove Windows Volume Shadow Copies, so does the Arrow ransomware variant Blammo@cock.li. This way, its developers seek to maximize ransom collection.

Those who have already been attacked by this virus can try to use free Dharma decryptor. The latter is the ancestor of Arrow and Blammo@cock.li so that the decryptor might work. Otherwise, you may need to remove Blammo@cock.li 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 Blammo@cock.li cannot be removed manually. The only way to decrypt data is to use a decryptor which can be obtained by contacting cybercriminals via vauvau@cock.li or Blammo@cock.li 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 Blammo@cock.li removal using FortectIntego, SpyHunter 5Combo Cleaner, Malwarebytes or another reputable anti-virus as soon as possible.

IMPORTANT: Blammo@cock.li 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 Blammo@cock.li virus.

Blammo@cock.li 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 bedynet.ru^[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.

Remove Blammo@cock.li virus and recover your files

Ransomware viruses, in general, are known to be high danger parasites. They initiate system’s modifications and lock personal files completely, thus leading their victims to data and money loss. To eliminate Arrow ransomware or any of its variants, you should use reputable security software. However, even the most reliable security software cannot protect your files. For that, you must take care of their backups that should be made as frequently as you can.

Manual Blammo@cock.li removal is not possible. There are way too much malicious files and processes that this ransomware runs. Most of them are hidden and protected by ransomware components, so removing them manually is not permitted. To remove Blammo@cock.li completely, you have to run a deep system scan and eliminate all malicious entries that it detects. After this procedure, you can try data recovery methods listed down below.
