@ethicalhack3r Get the cucumber lime zyns 3 and 6mg ones. Start with those. personally they make it really hard for me to justify quitting nicotine as I’m not having negative life or health outcomes using them.

I've been smoking on and off for 15 years and with zyns I don't smoke at all and I get significantly more out of my workouts, work, and general life. Nicotine skill issue.

Confession: I'm a dumb bitch What happened was I read on twitter dot com that nicotine when not smoked is actually an amazing nootropic that helps your concentration with no negative side effect. ...aaaaand after avoiding smoking for my entire adult life I'm now addicted to zyns. The don't even feel good anymore. I'm just popping them for no reason until I feel vaguely nauseous.

In 2025, 90 zero-days were exploited in the wild, with attackers increasingly targeting enterprise tech, while browser-based exploitation declined. State-sponsored espionage groups continued to prioritize edge and security appliances as key entry points.

🤓 I was one of the technical reviewers for the latest @veritasium video on the XZ backdoor.
It brought me back to the four days without sleep I spent analyzing this case!
They did a great job making the story accessible and keep the technical accuracy 👏

The window between vulnerability disclosure and real-world exploitation keeps shrinking.
The Zero Day Clock visualizes how fast attackers are operationalizing new CVEs. What used to take months now often happens in days, or hours.
The future needs to be Secure by Design.

Overnight we observed the first exploitation attempts against Cisco Catalyst SD-WAN in our honeypots.
Activity started around 03:00 UTC, leveraging the now-public PoC.
CVE-2026-20127
If you're running SD-WAN and haven't patched yet, now would be a good time.

My SolarWinds WHD blog is live, and it is fun:

- Decoding conflicts
- RCE through serialization
Enjoy🫡
