Aleksandr Nochvay is the security researcher of the Kaspersky Lab ICS CERT. His passion is studying network protocols without the source code of a software and he definitely likes to write tools for communication with these protocols. He considers the best vulnerabilities to be logical and architectural. One day, he found, that a software uses the string "TESTKEY" as an encryption key. He prefers to write reports about discovered vulnerabilities instead of advisories to developers.
