    The Glossary contains several hundred definitions of terms that you might come across in our articles and blogs, or on other information security sites. Unlike the in-depth articles in the Knowledge Base, every definition in the Glossary is succinct, while remaining highly informative. (This section is currently under construction)
  - Knowledge Base
    In the Knowledge Base, you will find various articles about common threats, a general classification of malware and unwanted messages, and a brief historical overview of the evolution of these and many other threats. The Knowledge Base now has three main sections: – The Detectable Objects section gives detailed information about malicious and potentially dangerous programs that we protect users against every single day all around the world, as well as advice on what to do in case of infection. – In the Spam and Phishing section, you will learn about phishing and spam mailings, how their creators earn money from them, and how this type of threat has evolved since the 1990s to the present day. – The articles in the Vulnerabilities and Hackers section is devoted to the topic of software vulnerabilities and how cybercriminals exploit them, as well as legislation and hackers in the broad sense of the word.

KRACK — Key Reinstallation Attack

A KRACK attack is a cyber attack aimed at compromising a Wi-Fi channel with WPA2 encryption. At the third stage of four-way validation of the cryptokey, the cybercriminal can resend the secret sequence and weaken the security of the connection. A KRACK attack can result in traffic interception, spoofing, or the transmission of falsified data packets to the client.
