Hi Asyn,

Hope this will help avast detection. Especially users with older Adobe Reader and Acrobat versions are vulnerable to the exploits used here:  Collab.collectEmailInfo() JavaScript Overflow (CVE-2007-5659) and Util.printf() JavaScript Overflow (CVE-2008-2992).
This malware takes advantage of a vulnerability to remotely access or attack a program, computer or server,

Nice the new https VT now has a 32MB upload limit.

Just hope they beef up the server as the load gets horrendous at times and this page took some time just to load, haven't tried submitting anything yet.

Hi DavidR,

Did they also fix the problem with loading newer VT result links?

I have no idea, as I said I haven't submitted anything so I didn't have a results link to test. But I honestly don't know what is going on with the links as I had never experienced the problem.

Well the link works, which is a good first step on the new.vt, the server is still slow. Don't particularly like the new layout too big and expanded, too much white space.

I like the additional information at the bottom is nice, this one is a bit of a strange beast as it give information on the "Sigcheck digital signature information" and this is saying it has a digital signature.

Quote from: VT sig Info
publisher................: Sun Microsystems, Inc.
product..................: Java(TM) Platform SE 6 U26
internal name............: javaw
copyright................: Copyright (c) 2011
original name............: javaw.exe
file version.............: 6.0.260.3
description..............: Java(TM) Platform SE binary

All the other info pulled from the file also indicates it is a Sun File, if it is a fake, they have gone to extraordinary lengths. But given its file size it is very large 888KB for javaw.exe (so suspect). I have an old copy for javaw.exe jre6 update 27 and that is only 141KB and that comes up clean on VT.

Since virtually all of the detections are generic/heuristic/crypt/packer. I would certainly send it to http://anubis.iseclab.org/?action=home for further detailed analysis.

Hi folks,

And as yet not fully functional for searching on a URL for file scan results. Asked jotti in a mail  to come up with a url scan link function as well, but the man there said as for now they cannot find the time to do it. Only alternative I have is Garyshood Online Virus Scanner with URL scan (hampered now because depending on VT reults?). This scanner - http://urlscan.chanret.com/ seems only to have DrWeb URL scanner results implemented, and I advise against the use of it because avast Web shield may alert the search results it delivers, for instance JS:Redirector-MX[Trj] was found when scanning for results on scanning  JS/Agent.aln   ARIN   AR   ivitor at -towebs.com   200.62.54.127    to 200.62.54.127   -dentalflores.com.ar   -http://dentalflores.com.ar (also blocked by Google Safebrowsing by the way - and WOT, see: http://www.webutation.net/go/review/dentalflores.com.ar )
