The best way to report a problem is to send an e-mail to email@example.com and include a complete description of the problem. CESNET-CERTS members will deal with the reported incident as soon as possible and will inform you that the problem, if any, has been solved and removed. You will receive a reply from firstname.lastname@example.org and the e-mail will be signed by our PGP Key.
Any offence against the Czech law, e.g.,
We do not expect everyone to be a computer security expert. This is the role of the CESNET-CERTS team.
We do not even expect everyone to be able to properly recognize, classify and describe a security incident. So, if you hesitate to report or not report, report it. The missing information will be asked if necessary.
Thanks for cooperation
The CESNET-CERTS Team
