netty-handler: Netty: Denial of Service due to eager buffer allocation in TLS handshake

A flaw was found in Netty, a network application framework. A remote attacker can exploit this vulnerability by sending a crafted TLS Transport Layer Security ClientHello message. This can lead to an eager allocation of a large memory buffer, causing a Denial of Service DoS due to excessive memor...

Secret Handshake - A Malware C2 Channel Using x509 Certs Over mTLS Motivation First off, why would I open source this? MITRE ATT&CK only talks about stolen or self-signed certs, and NDRs as far as I can tell pay very little attention to the content of x509 certificates outside of who is the issui...
