Her previous talks cover career transitions and advanced adversary tactics, given at BsidesLV, DEF CON, and SecTor. Feel free to say hi on LinkedIn or in the Lonely Hackers Club (LHC) Telegram chat, where she once (in)famously ranted about how commercial gun safes do not make for secure off-site data storage options.
