Kaspersky plus installer digitally signed but without countersignature, why?

[fabiodanzetta]

Hello everyone,
as per the subject I noticed that the Kaspersky Plus installation file is digitally signed but the countersignature with relative timestamp is missing.
It's the first time I've seen a setup of a security product without the countersignature with relative timestamp.
Can anyone explain to me why? Is there a particular reason?
Attached is the screenshot

Thanks everyone

Hello @fabiodanzetta, 

Welcome back!

This topic has been discussed & answered previously; we've just spent an hour looking for the original discussion, the generic search produces between 18 & 34 pages of topics - depending on the search criteria; we've run out of time; more pressing things to attend to; please feel free to search - it's in the repository somewhere. Note - it's not the clam discussion, raised in 2019, where similar question(s) were raised. 

Related Kaspersky documentation, read: 

• How to verify if the downloaded Kaspersky Lab installer is genuine. 
• Errors 1330 and "Digital Signature of installation files is missing”.

Thank you🙏

Hi @Flood and Flood's wife ,

I have to be honest, I searched all over the forum and could not find the discussion where my same issue is mentioned.
Could you please point me to it?

Thank you again for your helpfulness.

Hi @fabiodanzetta, 

Thank you for posting back! 

If we could've found it we would have put it here -> we've searched & searched - it's *very* time consuming; we did find (your) 2019 topic where you raised the issue. 

Sadly the search filter is not brilliant; a single word search is often the most successful - but - that also means looking thru pages & pages of topics = hundreds of topics... 

When (we've) raised it with the experts their advice was: There is no countersignature and if you will click on View certificate then you will see Issued by section with Kaspersky Lab info (no information about certification authority here. the certificate is self-signed). This signature(certificate) is not required to be installed in the OS storage. Unfortunately we can't provide more deep information. 

IF the attached documentation is not helpful, please raise it with the Kaspersky experts by logging a request & then do what (you) do so well: share the information with the Community😊

Thank you🙏

Hi all,
support replied to me that the lack of timestamp for the application installation file is expected by design so nothing abnormal.
If you want the timestamp I saw that it is present in the full installation package.
