hi! I have some questions about OPSEC and hope you guys can help me. Is it dangerous to surf/order at DNMs when connected to homeinternet via a 2nd hand throwaway notebook with latest TAILS installed on a USB stick? What if another normal computer is surfing on the internet within the same network/router? ...and what about storing passwords? Is it dangerous to make a txt file on the persistent storage of tails? ...the persistent storage is secured with a password only saved in my head so it should be save enough!? Is XMPP with OTR activated secure? and is jabber.hot-chilli.eu a good server? ...thanks, MIA!
Use Tor bridges for your connection.
Use KeePassX within Tails to generate and store your passwords. Use a keyfile and set password a phrase from your favorite book, a song lyric, whatever.
The OTR plugin is secure for chat/xmpp.
Make REGULAR backups of your usb stick/persistent volume and keep it offsite.
