W32/Sober.J@mm

Spreading

When Sober.J@mm is run it copies itself to the %SystemRoot%, constructing its new file-name from these strings:  sys host dir expoler win run log 32 disc crypt data diag spool service smss32 The worm then creates the following registry entries to ensure it is started each time Windows loads:  HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\
= “%SystemRoot%\" HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\
= “%SystemRoot%\" A new is generated for each entry from the same wordlist that’s used to build the filename. The worm also creates the following files in the %SystemRoot% directory:  datamx.dam (Harvested email addresses) dgsfzipp.gmx (MIME encoded archive, containing a copy of the worm) dgssxy.yoi (Used to disable previous Sober variants) nonrunso.ber (Used to disable previous Sober variants) Odin-Anon.Ger (Used to disable previous Sober variants) read.me (Harmless text file) sysmms32.lla (Used to disable previous Sober variants) Mail propogation Sober.J harvests email addresses from files with these extensions:  pmr phtm stm slk inbox imb csv bak imh xhtml imm imh cms nws vcf ctl dhtm cgi pp ppt msg jsp oft vbs uin ldb abc pst cfg mdw mbx mdx mda adp nab fdb vap dsp ade sln dsw mde frm bas adr cls ini ldif log mdb xml wsh tbb abx abd adb pl rtf mmf doc ods nch xls nsf txt wab eml hlp mht nfo php asp shtml dbx As previously mentioned the worm stores results in %SystemRoot%\datamx.dam, however, addresses containing the following strings are ignored:  ntp-ntp@ ntp. info@ test@ office @www @from. support smtp- @smtp. gold-certs ftp. .dial. .ppp. anyone subscribe announce @gmetref sql. someone nothing you@ user@ reciver@ somebody secure me@ whatever@ whoever@ anywhere yourname mustermann@ .kundenserver. mailer-daemon variabel password noreply -dav law2 .sul.t- .qmail@ t-ipconnect t-dialin ipt.aol time postmas service freeav @ca. abuse winrar domain. host. viren bitdefender spybot detection ewido. emsisoft linux google @foo. winzip @example. bellcore. @arin mozilla @iana @avp icrosoft. @sophos @panda @kaspers free-av antivir virus verizon. @ikarus. @nai. @messagelab nlpmail01. clock Next, Sober.J mails itself to all harvested address. Mails may appear in English or German, with the following characteristics: Subject  I've got YOUR email on my account!! Ey du DOOF Nase, warum beantw...Body  Hello,First, Sorry for my very bad English!Someone send your private mails on my email account!I think it's an Mail-Provider or SMTP error.Normally, I delete such emails immediately, but in the mail-text is a name& adress.
