My personal Involvement

PGP Certificate

  • My first PGP certificate is of 1998-03-16, created with “PGPfreeware 5.0i” :-).

E-Mail Account Hacking & Implementation of Filter Rules to Forward all E-Mails to the Hacker

  • On March 15, 2023, my email account was hacked and the hacker created 2 filter rules :-(:
    1. Email priority is “normal” ⇒ Delete email immediately
    2. All new emails ⇒ Forward email to the hacker's E-Mail @ gmx.com.
  • Although I noticed that I had to reset my password on 2023-02-15, but that a hacker had logged in with the e-mail account password that was otherwise rarely used elsewhere, if at all, in order to simply create new filter rules, I had missed it. A new password wouldn't have changed anything :-(.
  • It wasn't until 2024-02-20 that I noticed that I only had new emails in the GMX spam folder, but no normal new emails, and that a test sending of emails to my account didn't result in this that they were in the normal email folder :-(.
  • So I just changed the password and deleted the filter rules :-).
  • I now noticed that I had also used the GMX password for (ex-eBay) Kleinanzeigen.de, and that Kleinanzeigen.de notified me of a change in the password by email on 2024-02-15. I was unable to reset my Kleinanzeigen.de password (?).

Zero Trust Security

  • Expert told me in 2024-03:
    • “Zero-trust network access” ( ZTNA ) and “Security Service Edge” ( SSE ) are the successors of VPN.
    • Problems but which can be solved: Server-initiated traffic, as standard with voice-over-IP telephony & video calls: A user connect to a server, but the server initiates it's own connection back to the client(s).
      • Example with a SIP phone call: A user asks the server to connect to another user, but the server itself initiates a data stream between both users.
  • Google - Search for "zero trust network access".
  • DE.Wikipedia "Zero trust security model", DE.Wikipedia "Zero Trust Security".
