What is Magniber ransomware? And how does it carry out its attack?

Magniber ransomware is a new ransomware infection which is being distributed by the Magnitude Exploit Kit and appears to be a new version of the Cerber ransomware. According to reports, Magiber ransomware’s first victims are from South Korea as well as some parts of Southeast Asia. It had gotten its name Magniber from the way it was facilitated using the Magnitude Exploit Kit.
The onset of the hacker campaign started when the cyber crooks loaded a newly devised malware into the Magnitude Exploit Kit. The same mechanism was used by Cerber ransomware strains. Security reports indicated that the captured strains are merely the first releases of the ransomware. One of the key characteristics of the Magnitude Exploit Kit is the fact that it is made specifically to infect users from South Korea and based on the reports, the email message is the preferred delivery mechanism.
Once the ransomware infects a computer, a number of attack sequences can be programmed. And depending on the configuration, it may feature different modules which can be activated or executed on the infected computer. Example of the modules includes Trojans, data theft and additional malware delivery. Magniber’s initial infiltration begins when it is copied to a temporary folder which can be changed according to the initial configuration. After Magniber’s files are changed with some random names, they are set for automatic startup when the infected PC boots.
Magniber ransomware has lots of important characteristics – one of which is that it is able to spawn other malicious processes which are under its control. It can also interact with the child processes and inject some data on them. And one of the reasons why it is considered to be a dangerous threat is that some programs in the infected computer might be used to confuse users so that it can extract information from the users. For instance, an web browser which Magniber have messed with, if any sensitive information such as banking details, passwords, etc. is entered by the unsuspecting user, all the information will be recorded by the ransomware and sent to the crooks behind it. Moreover, this ransomware can also run shell commands all on its own, to make things worse, when it runs a shell command combined with some Trojan modules, it gives the cyber crooks nearly unlimited capabilities on using the victim’s computer remotely.
Magniber’s end goal is to blackmail users by using typical ransomware techniques. All the user’s files will be encrypted with a strong encryption algorithm security researchers were able to extract the bundled list of the captured strains and shows that Magniber targets files with the following extensions (these are just half of the extensions as the list is quite long):
doc, docx, xls, xlsx, ppt, pptx, pst, ost, msg, em, vsd, vsdx, csv, rtf, 123, wks, wk1, pdf, dwg, onetoc2, snt, docb, docm, dot, dotm, dotx, xlsm, xlsb, xlw, xlt, xlm, xlc, xltx, xltm, pptm, pot, pps, ppsm, ppsx, ppam, potx, potm, edb, hwp, 602, sxi, sti, sldx, sldm, vdi, vmx, gpg, aes, raw, cgm, nef, psd, ai, svg, djvu, sh, class, jar, java, rb, asp, php, jsp, brd, sch, dch, dip, p, vb, vbs, ps1, js, asm, h, pas, cpp, c, cs, suo, sln, ldf, mdf, ibd, myi, myd, frm, odb, dbf, db, mdb, accdb, sq, sqlitedb, sqlite3, asc, lay6, lay, mm, sxm, otg, odg, uop, std, sxd, otp, odp, wb2, slk, dif, stc, sxc, ots, ods, 3dm, max, 3ds, uot, stw, sxw, ott, odt, pem, p12, csr, crt, key, pfx, der, 1cd, cd, arw, jpe, eq, adp, odm, dbc, frx, db2, dbs, pds, pdt, dt, cf, cfu, mx, epf, kdbx, erf, vrp, grs, geo, st, pff, mft, efd, rib, ma, lwo, lws, m3d, mb, obj, x, x3d, c4d, fbx, dgn, 4db, 4d, 4mp, abs, adn, a3d, aft, ahd, alf, ask, awdb, azz, bdb, bib, bnd, bok, btr, cdb, ckp, clkw, cma, crd, dad, daf, db3, dbk, dbt, dbv, dbx, dcb, dct, dcx, dd, df1, dmo, dnc, dp1, dqy, dsk, dsn, dta, dtsx, dx, eco, ecx, emd, fcd, fic, fid, fi, fm5, fo, fp3, fp4, fp5, fp7, fpt, fzb, fzv, gdb, gwi, hdb, his, ib, idc, ihx, itdb, itw, jtx, kdb, lgc, maq, mdn, mdt, mrg, mud, mwb, s3m, ndf, ns2, ns3, ns4, nsf, nv2, nyf, oce, oqy, ora, orx, owc, owg, oyx, p96, p97, pan, pdb, pdm, phm, pnz, pth, pwa, qpx, qry, qvd, rctd, rdb, rpd, rsd, sbf, sdb, sdf, spq, sqb, stp, str, tcx, tdt, te, tmd, trm, udb, usr, v12, vdb, vpd, wdb, wmdb, xdb, xld, xlgc, zdb, zdc, cdr, cdr3, abw, act, aim, ans, apt, ase, aty, awp, awt, aww, bad, bbs, bdp, bdr, bean, bna, boc, btd, cnm, crw, cyi, dca, dgs, diz, dne, docz, dsv, dvi, dx, eio, eit, emlx, epp, err, etf, etx, euc, faq, fb2, fb, fcf, fdf, fdr, fds, fdt, fdx, fdxt, fes, fft, flr, fodt, gtp, frt, fwdn, fxc, gdoc, gio, gpn, gsd, gthr, gv, hbk, hht, hs, htc, hz, idx, ii, ipf, jis, joe, jp1, jrtf, kes, klg, knt, kon, kwd, lbt, lis, lit, lnt, lp2, lrc, lst, ltr, ltx, lue, luf, lwp, lyt, lyx, man, map, mbox, me, mel, min, mnt, mwp, nfo, njx, now, nzb, ocr, odo, of, oft, ort, p7s, pfs, pjt, prt, psw, pu, pvj, pvm, pwi, pwr, qd, rad, rft, ris, rng, rpt, rst, rt, rtd, rtx, run, rzk, rzn, saf, sam, scc, scm, sct, scw, sdm, sdoc, sdw, sgm, sig, sla, sls, smf, sms, ssa, sty, sub, sxg, tab, tdf, tex, text, thp, tlb, tm, tmv, tmx, tpc, tvj, u3d, u3i, unx, uof, upd, utf8, utxt, vct, vnt, vw, wbk, wcf, wgz, wn, wp, wp4, wp5, wp6, wp7, wpa, wpd, wp, wps, wpt, wpw, wri, wsc, wsd, wsh, wtx, xd, xlf, xps, xwp, xy3, xyp, xyw, ybk, ym, zabw, zw, abm, afx, agif, agp, aic, albm, apd, apm, apng, aps, apx, art, asw, bay, bm2, bmx, brk, brn, brt, bss, bti, c4, ca, cals, can, cd5, cdc, cdg, cimg, cin, cit, colz, cpc, cpd, cpg, cps, cpx, cr2, ct, dc2, dcr, dds, dgt, dib, djv, dm3, dmi, vue, dpx, wire, drz, dt2, dtw, dv, ecw, eip, exr, fa, fax, fpos, fpx, g3, gcdp, gfb, gfie, ggr
During the encryption, Magniber appends random extensions to the encrypted files such as .lhsdj or .kgpvwner. After it encrypts the targeted files, the ransomware communicates with the command and control server to report the encrypted files. The experts found that the ransomware does not target certain critical folders that may render the system unusable. These certain folders are as follows:
:\documents and settings\all users\
:\documents and settings\default user\
:\documents and settings\localservice\
:\documents and settings\networkservice\
\local settings\
\public\music\sample music\
\public\pictures\sample pictures\
\public\videos\sample videos\
\tor browser\
\program files (x86)
\program files
\system volume information
After the encryption, Magniber ransomware drops its ransom note named READ_ME_FOR_DECRYPT_[id].txt on each folder where there are encrypted files. The ransom note contains the following content:
ALL Y0UR D0CUMENTS, PHOTOS, DATABASES AND OTHER IMP0RTANT FILES HAVE BEEN ENCRYPTED! ====================================================================================================
 “Your files are NOT damaged! Your files are modified only. This modification is reversible.
 The only 1 way to decrypt your files is to receive the private key and decryption program.
 Any attempts to restore your files with the third-party software will be fatal for your files! ====================================================================================================
 To receive the private key and decryption program follow the instructions below:

  1. Download “Tor Browser” from https://www.torproject.org/ and install it.
  2. In the “Tor Browser” open your personal page here:

 Note! This page is available via “Tor Browser” only. ====================================================================================================
 Also you can use temporary addresses on your personal page without using “Tor Browser”:
 Note! These are temporary addresses! They will be available for a limited amount of time!”
