3.3 Million Mail Servers Vulnerable: Is Your Email a Sitting Duck for Hackers?
POP3 and IMAP mail servers without TLS encryption are like open diaries for hackers. With 3.3 million servers exposed, it’s a dream gig for network sniffers. ShadowServer is urging operators to enable TLS encryption to stop passwords from being served on a silver platter. Time to upgrade from digital sitting ducks to safe, encrypted swans!

Hot Take:
Looks like some mail servers are still partying like it’s 1999, with no TLS in sight! These servers are practically sending out open invitations to snoopers, saying, “Come one, come all, see our usernames and passwords in plain text!” It’s like they’ve never heard of the 21st century—or cyber hygiene.
Key Points:
- Over 3.3 million mail servers are exposed without TLS encryption.
- IMAP and POP3 email protocols transmit data without encryption, making them vulnerable.
- ShadowServer is alerting operators about this glaring security risk.
- Modern TLS protocols (1.3) are recommended for securing email communications.
- Major tech companies have phased out older TLS versions due to security concerns.
