Oracle have laid off 30k employees today. They did it to personal email accounts at 6am 🫡 saying they needed the money to spend on GenAI instead. https://thenextweb.com/news/oracle-layoffs-march-2026

Defender 1: This appliance is running an ancient AF version, how is it not a smoking ruin at this point?

Defender 2: Well, it turns out that all of the attacker scanning tools use libraries that have disabled TLS before 1.0 and this appliance only supports SSL v3 sooo....

  • OpenSSL 1.1.1 sets the default min to TLS 1.0
  • Python 2.7 / 3.6 set the default min to TLS 1.0 but depend on the underlying crypto lib.
  • Go default min prior to 1.18 was TLS 1.0
  • curl default min was TLS 1.0 from curl 7.39.0 to 8.15.x
  • wget uses underlying lib

"To eat my mother's pancakes again, just like when I was a child."

"Are you sure?"

"You think it frivolous?"

"No. But to grant it I must send you back to the child you were, with no adult memories."

"Would my life change?"

"You ask that every time."

Last week, half of all new scanning IPs observed by GreyNoise geolocated to Hong Kong.

A quarter-million of them never completed a TCP handshake.

The ones that did were scanning MySQL, SSH, SMB, and RDP across 20+ countries.

One of these is the signal. The other is noise.

US Administration: We're having great and productive talks with the Iranian leadership.

Iranian leadership: lol, wut?

The common response to this is that one or both parties are lying.

My personal headcannon is that the US Admin got taken in by a 419 (Nigerian prince) scam.

"Hello Glorious President,

I a diplomat of the current Iranian regime. We would like to bow to your magnificence, surrender completely, and provide you with complete control of the Iran and billions of US dollers. Unfortunately to do this we will have to file a small "surrender" fee of 100 million US dollars. ....."
