What is CryptoWire ransomware? And how does it execute its attack?
CryptoWire ransomware is an open-source crypto-virus that first unleashed its attack to many users way back in 2016. It came back in March 2017 and now, apparently, its developers decided to update this ransomware and now it’s back to target gullible victims to demand ransom from them.
Once it executes its attack, CryptoWire ransomware will target file located in the deeper folders and finishes with the desktop folder. It targets a total of 282 file types such as:
3fr, 7z, EPS, M3U, M4A, PEM, PSD, WPS, XLSX, abw, accdb, afsnit, ai, aif, arc, arw, as, asc, asd, asf, ashdisc, asm, asp, aspx, asx, aup, avi, bay, bbb, bdb, bibtex, bkf, bmp, bmp, bpn, btd, bz2, c, cdi, cdr, cer, cert, cfm, cgi, cpio, cpp, cr2, crt, crw, csr, cue, dbf, dcr, dds, dem, der, dmg, dng, doc, docm, docx, dsb, dwg, dxf, dxg, eddx, edoc, eml, emlx, eps, epub, erf, fdf, ffu, flv, gam, gcode, gho, gpx, gz, h, hbk, hdd, hds, himmel, hpp, ics, idml, iff, img, indd, ipd, iso, isz, iwa, j2k, jp2, jpeg, jpf, jpg, jpm, jpx, jsp, jspa, jspx, jst, kdc, key, keynote, kml, kmz, lic, lwp, lzma, m4v, max, mbox, md2, mdb, mdbackup, mddata, mdf, mdinfo, mds, mef, mid, mov, mp3, mp4, mpa, mpb, mpeg, mpg, mpj, mpp, mrw, msg, mso, nba, nbf, nbi, nbu, nbz, nco, nef, nes, note, nrg, nri, nrw, odb, odc, odm, odp, ods, odt, ogg, one, orf, ova, ovf, oxps, p12, p2i, p65, p7, p7b, p7c, pages, pct, pdd, pdf, pef, pem, pfx, php, php3, php4, php5, phps, phpx, phpxx, phtm, phtml, pl, plist, pmd, pmx, png, ppdf, pps, ppsm, ppsx, ppt, pptm, pptx, ps, psd, pspimage, pst, ptx, pub, pvm, qcn, qcow, qcow2, qt, r3d, ra, raf, rar, raw, rm, rtf, rtf, rw2, rwl, s, sbf, set, skb, slf, sme, smm, snp, spb, sql, sr2, srf, srt, srw, ssc, ssi, stg, stl, svg, swf, sxw, syncdb, tager, tc, tex, tga, thm, tif, tiff, til, toast, torrent, txt, vbk, vcard, vcd, vcf, vdi, vfs4, vhd, vhdx, vmdk, vob, vsdx, wav, wb2, wbk, wbverify, webm, wmb, wpb, wpd, wps, x3f, xdw, xlk, xlr, xls, xlsb, xlsm, xlsx, xz, yuv, zip, zipx
Once it encrypts files, CryptoWire ransomware does not change the encrypted files’ extensions unlike other similar threats. It will deliver all the information about the attack to a remote server and generates a program window containing the ransom note that states:
“Your files has been safely encrypted
The only way you can recover your files is to buy a decryption key
The payment method is Bitcoins. The price is $200 = 0.2909 Bitcoins’
When you are ready, send a message by email to [email protected]
We will send you our BTC wallet for the transfer
After confirmation we will send you the decryption key
Click on the ‘Buy decryption key’ button.”
How is the malicious payload of CryptoWire ransomware disseminated?
The malicious payload of CryptoWire ransomware is disseminated in an obfuscated form via spam emails. This is why you have to be careful when opening emails especially if it seems like the email is shady. Cyber crooks tend to disguise the malware-laden emails and use the names of popular companies or groups to lure you into opening the email and downloading the corrupted file.

Restore the previous state of your files using the Shadow Volume copies
Restoring your encrypted files using Windows’ Previous Versions feature will only be effective if CryptoWire ransomware hasn’t deleted the shadow copies of your files. But still, this is one of the best and free methods there is, so it’s definitely worth a shot.
To restore the encrypted file, right-click on it and select Properties, a new window will pop-up, then proceed to Previous Versions. It will load the file’s previous version before it was modified. After it loads, select any of the previous versions displayed on the list like the one in the illustration below. And then click the Restore button.
