We have been hit my a bunch of emails with a zipped SCR attachment. Antivirus is not detecting them.

Subject is either "Payment invoice has been pai" or "The payment has been mad".

Attachment is "invoiceXXXXXX_pdf.zip" where the Xs are random numbers.

Anyone else getting these?

Have seen lots of these types of emails lately. Mostly they seem to be the cryptolocker virus or a variant of. It was enough to make me block .zip files at the gateway.

What antivirus do you use, and is it detecting it?

Can't find much about it, but it seems to infect the PC if the attachment is run and then sends itself out via Outlook (not sure about other mail clients). And it looks like currently most AV scanners miss it.

I got it to my small business email. The way I figure it if money arrives in my account I wasn't expecting then I'll open the email telling me what it is.

I've blocked anything with _pdf.zip in the attachment name, but maybe I should change it to all zip files. We have two different virus engines scanning them, one at the Gateway and one in Exchange and neithe ris picking them up.

Our Symantec Brightmail Appliance is picking them up but I don't think SEP is on the desktops:

This attachment contained a virus and was stripped.

Yep, Happening with us. The latest SEP desktop definition isn't picking them up yet but luckily Symantec Message Labs is blocking them now.

Hi, we got hit with this across several PCs with users opening the attachment and it initiating sending of itself to as many contacts as it could. It looked like it was partly stopped trying to write protected OS files, fortunately no one with elevated user rights was silly enough to open the attachment :-)

Our ESET antivirus is updated hourly and this particular threat wasn't in the database - an update to ESET was issued at about 12:30 with this included and it is now being detected.
It's rare for this to happen like this, my guess is that there will be many many organisations being hit by this.

We have received quite a few also; Symantec Cloud on the desktops is blocking it when people try to open the attachment, but annoying it is getting that far!

I have an infected PC here
It sends out mass mailings through exchange : check the exch que, but wont show in the sent items (on this PC)

Nod will detect leftovers in the tmp files and now seems to detect the email attachment
NOD32 still wont detect the infection if PC is infected, its a jibberish exe in C:\windows

Malwarebytes will detect that infected file, but being so new Im uncertain what other files could be infected on the PC.
It seems to POSSIBLY add/infect a systemservice

If anyone has any links to removal writeups or latest info for this infection I'd appreciate it . I dont want to put the PC back on the network untill Im
sure its clean, may be undected malware on it still
Unfortunately new malware is often give all too generic names .

I thought it would show up in sent items if it is using the local client to send?? Fortunately we haven't become infected here, but would be nice to let users know that they would show up in sent items for them to check their home computers.

If it doesn't show up in sent items is there an easy way for a home user on POP to check?
