Malware submission question

When encountering an unknown sample, is it sufficient to scan the sample using VT or Jotti, since those services claim to distribute uploaded samples to malware vendors?

 

I would just zip it and sent it ti the vendor you like.
I'm not sure if jotti does the same thing

 

I was thinking to ask almost the same question.

 

also Jotti does. But some av vendors give low priority to mass submitted samples that come e.g. from jotti or virustotal.

 

Thanks for the reply.

 

it would be better to send them to the vendor itself. As far as I've seen Avira is watching more carefully the VirusTotal and Jotti's submission, others don't.

 

You forget Ewido.

Anyway, I also think its better to send samples directly to vendors. Jotti's and VT samples are usually lower priority because they often contain lots of corrupted files, which leads to increased amount of time wasted in analysing such files.
