PSS Security Response Team Alert - New Virus: W32.Blaster.worm

SEVERITY: CRITICAL
DATE: August 11, 2003
PRODUCTS AFFECTED: Windows XP, Windows 2000, Windows Server 2003, Windows NT 4.0, NT 4.0 Terminal Services Edition

WHAT IS IT?
The Microsoft Product Support Services Security Team is issuing this alert to inform customers about a new worm named W32.Blaster.Worm which is spreading in the wild. This virus is also known as: W32/Lovsan.worm (McAfee), WORM_MSBLAST.A (Trendmicro), Win32.Posa.Worm (Computer Associates). Best practices, such as applying security patch MS03-026 should prevent infection from this worm.

Customers that have previously applied the security patch MS03-026 before today are protected and no further action is required.

IMPACT OF ATTACK: Spread through open RPC ports. Customer's machine gets re-booted or has mblast.exe exists on customer's system.

TECHNICAL DETAILS: This worm scans a random IP range to look for vulnerable systems on TCP port 135. The worm attempts to exploit the DCOM RPC vulnerability patched by MS03-026.

Once the Exploit code is sent to a system, it downloads and executes the file MSBLAST.EXE from a remote system via TFTP. Once run, the worm creates the registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run "windows auto update" = msblast.exe I just want to say LOVE YOU SAN!! bill

Symptoms of the virus: Some customer may not notice any symptoms at all. A typical symptom is the system is rebooting every few minutes without user input. Customers may also see:

- Presence of unusual TFTP* files
- Presence of the file msblast.exe in the WINDOWS SYSTEM32 directory

To detect this virus, search for msblast.exe in the WINDOWS SYSTEM32 directory or download the latest anti-virus software signature from your anti-virus vendor and scan your machine.

Tale popravek reši zadevo...

Gre za črva W32.Blaster, ki pa izkorišča luknjo v MS RPC servisu.

Windowsi imajo luknjo, za katero obstaja popravek od 16. julija, ta črv / virus pa izkorišča to luknjo.

dela, preverjeno

ajde

Hm ce bi jz to temo odkril en dan prej, bi blo tud fajn (ne pa da sem studiru par ur v cem bi bil problem). Sam men je zonealarm ustavu tega hudica, tak da se racunalniku ni ratal ugasnat. Sam kokr sem ga pa ugasnu (zone alarm seveda), pa lepo nov zagon. No pol pa sem iz predala potegnu nortona, ga updajtal na najnovejsi datum, in je takoj odkril tega msblasta. Pol pa se sam popravek in konec.

ko sem jst fasu tega črva, seveda pojma nisem imel, kaj za vraga bi to lahko bilo.

Ves paničen sem si vzel 2 uri časa in ves pameten formatiral disk! Ampak črv se je po 5 minutah spet pojavil! Še dobro, da sem se uspel privlečt do slo-techa! Ker bi skoraj živce izgubil

jaoooooooooooooo

heh..meni pa se je samo modem(kablski)parkrat resetiral, pa sn že mislo kaj je:)))))
pol pa spet normalno delal mater mam srečo
sej bo tak počasi fertik tega črva
LoL

Če ima še kdo probleme, naj proba tudi z Ad-Aware. Nov reference file detecta tudi blasta, potem ko si zadevo snamete dol, najprej kliknite na ikonico "open webupdate" in potem kliknite connect, potem pa preglejte cel sistem.

Panda rox!!! "Welcome to Panda Antivirus."

Če še kdo ni uspel rešiti problema z omenjenim črvom ali pa želi kaj več izvedeti v slovenskem jeziku, lahko poskusi tudi s spletno stranjo Arnesove varnostne službe SI-CERT, kjer dajejo tudi link za slovenska navodila odstranitve hrošča: http://www.arnes.si/si-cert/obvestila/2003-04.html

Predvčeraj sem ga dobil pa nisem posumil na MSBlasta. Včeraj sem posodobil AVGuard, ki mi ga je našel a tudi brisanje ni pomagalo. Naredil sem vse, kar so navodila zahtevala a vseeno se je znova pojavil (nikjer ni bilo tistih značilnih znakov črva v registru in med servisi, niti datoteke msblast.exe). Probal sem namestiti popravek, pa me je vrglo v shutdown (56k modem). Nazadnje mi je uspelo. Ko mi je AVGuard javil, da je našel MSBlasta, sem ga pustil na ekranu in vseeno DL-al popravek. Čez nekaj časa se je odštevanje vseeno začelo a inštalacija popravka se je ravno končala. Če mi igra s časom ne bi uspela, bi računalnik odnesel k sestri na ADSL in tam zagotovo prehitel črva. Po uspehu sem DLal večino zame relevantnih popravkov (2 uri).

Mislim, da se je ta popravek lahko nekje DLal brez same inštalacije. Če to res drži, popravek pač skine kolega, ga zapeče na CD in voila.

... ki pa v Windows 2000 (in verjetno še kje) ne deluje ...

Klici microsoft. Bodi ze pomagal. Siish.

Ja, naprej je treba ubiti proces msblast, preden se spravite doldajati popravke. Vsaj jaz sem imel takšne izkušnje, kot sem to delal (sosedom, da na bo pomote).

z firewallom teh tezav ne bi bilo...

R0K,podoben problem sem mel sam ko sem kolegu nalagal XP.naložim in vpišem IP in zaženem IE in čez nekaj cajta že odštevanje. Samo pol pa več v winse nisem mogel,niti v safe mode.tako da sem moral jovo na novo.samo sem pol takoj SP1 naložo+nove popravke in nortona upgrejdal. Se povežem na net,norton ga zazna,hitro na symantec stran da dol povlečem orodje za odstranitev in MS popravek.Pol pa sem bil rešen.
Sem pa vido da se pripravlja novi virus,ki najde luknjo v DX in tokrat so izpostavljeni vsi operacijski systemi. Več o novici tukaj.

{C_maniak}: nikad nisi tako dobro zavarovan, da ti nic nebi mogli

Hudo je tole... sem jih tud jaz že nekaj odstranil. Pr enmu frendu je pa fotr ponoru pa je kr nesu na servis formatirat kavni mlinček... Hudo. Predvsem to, da serviser ni pokapiral za kaj se gre.

Ce se vam masina resetira se preden uspete naloziti popravek, si lahko pomagate na sledec nacin: Pod servisi(desna tipka na My computer->manage->Services and Applications->Services) poiscete servis "Remote Procedure Call(RPC)". Pod recovery imate tri nastavitve za "failure", ki so po defoltu nastavljene na "Restart the Computer". Zacasno jih nastavite na "Restart the Service", potegnete dol popravek, pol pa nastavite nazaj kot je bilo na zacetku! SAm tega v praksi nisem sprobal, ker mi je uspelpotegniti dol popravek se preden se je masina restartala!

Če dobiš could not verify file integrity, pol še enkrat dol potegni al pa dol potegni na drugem računalu.
