Being fully aware of this kind of threat, we're continously working on improving Tails' security in depth. Among other tasks, we're working on a tight integration of AppArmor in Tails, [[!tails_ticket desc="kernel" 7639]] and [[!tails_ticket desc="web browser hardening" 5802]] as well as [[!tails_ticket desc="sandboxing" 6081]], just to name a few examples.
We are happy about every contribution which protects our users further from deanonymization and helps them to protect their private data, investigations, and their lives. If you are a security researcher, please audit Tails, Debian, Tor or any other piece of software we ship. To report or discuss vulnerabilities you discover, please get in touch with us by sending email to <tails@boum.org>.
