Untrusted Network is my personal blog, on which I mainly cover current cyber security events and topics.

I’m a co-owner of Nettles Consulting - a company through which I offer wide range of cyber security services - and one of the Handlers at the SANS Internet Storm Center.

The views and opinions expressed on this website are my own and do not necessarily reflect those of any past or present employer or of any third party mentioned in the articles, unless explicitly stated otherwise.

Should you need to get in touch with me, you may use DM on Twitter (see the page footer) or write me an e-mail to jan/dot/kopriva/at/untrustednetwork/dot/net.
