More malware analyses

Aryeh Goretsky, who I've know for a long long time, is currently at Eset (they make anti-malware software) suggested to me a couple of places other than VirusTotal to try, so I did.

Dear customer

The confirmation invoice for order 1366976 is attached.

Please let me know if you need any other paperwork.


Best regards,

Enclosed was an XLS spreadsheet. I'm pretty sure it's malware, I haven't ever bought anything from Abcam. The XLS file has a SHA256

aefc76a6cca8f9b903f78e9829b6da68b8e236ae00aba8218d8f4f1b236e2624

SHA1  e681f239b8bd63af26630410c340d83bad53fe10
MD5   7a2b2afb94c7a5ae18dd3456b559a7c0

According to VirusTotal, 8 products (out of 54) flag it as malware.

AVware
Arcabit
ESET-NOD32
Fortinet    
Panda    
Sophos    
TrendMicro    
VIPRE

According to Jotti, the following four products flagged it:

Eset, Fortinet, Kaspersky and Sophos.

Of the products that flagged it with VirusTotal, Arcabit and Trend found nothing


According to Opswat Metascan online, four out of 43 flagged it.

Kaspersky, Preventon, Sophos and ThreatTrack.

Of the products that flagged it with VirusTotal, Eset, Fortinet, TrendMicro found nothing,


So a threat that arrived in my mailbox, is flagged by about 10% of products.

  1. I still working on you idea about email flitttering, it will be ready hurley January, if you would like you free copies please send me youse bank details, (to proof identification) and I will sends you your vary own copy to review and yous can keep it.

    But really i am concerned, we use Kaspersky here, and I wonder if we should change it, although to be fair I'm not aware of very many virus/threats getting through.

  2. Thanks for your kind offer of an email filter, but I already have my own. Perhaps one of the readers of this blog will take you up on the offer.

    I don't know how well Kaspersky compares with other products. Maybe you should upload some of the suspicious files that arrive in your mailbox to one of the three sites I cite above, that will check it against a bunch of products.
