How To Contact Us

We do get a lot of mail. For issues that aren't sensitive our community forums may be more suitable. For example, if you want to learn about a particular security related topic, or you would like some input regarding a packet trace you collected (and you don't mind sharing it in public), post it to the community forums.

Note about attached files: Please attach any files "as found". If necessary, zip or tar multiple files into one. But try not to encrypt or obfuscate the files, as this may hinder analysis.

To anybody scanning this site for vulnerabilities: We enourage our readers to use this form to submit malicious code, viruses, spyware and all kinds of evil files. Us not filtering uploads for extensions like ".exe" is not a vulnerability, it is a feature. Submitting a vulnerability stating so shows that you have not actually read this notice and just used a lazy automated tool.
