Heartbroken to hear about the passing of @Skvern0. He was one of the best threat hunters in the industry - even APTs were afraid of him. I’m grateful for the time we worked together and for everything I learned from him. Rest in peace.

It turned out there are many more payloads used in the Notepad++ attack! To stay undetected, its masterminds were COMPLETELY changing execution chains about every month.
Here are more IPs used in the attack:

⚠️ URGENT WARNING ⚠️
I’m sharing this as something urgent and important please be careful, everyone.
Linda is my friend. She used to work in capital markets, and we met years ago. Yesterday, she asked me to join a meeting. I thought it was for a project and accepted. She sent me a calendar invite, and I joined the meeting this morning at 9 AM.
It was supposed to be on Google Meet, but no one was there. Then they sent me a Zoom link. I clicked it and opened it in my browser.
When I joined, everything looked broken and the page asked me to run a “system update.”
Instead, I chose to download Zoom manually and asked for the meeting ID.
They refused to give it and said the update would be “easier.”
That’s when I deleted everything and shut it down.
I told them my computer couldn’t handle the update and that we should continue on Meet.
Strangely, my camera wouldn’t turn off no matter what I did.
I calmly closed all tabs, deleted everything, restarted my browser, and ran a full virus scan.
Then I realized Linda had been hacked, and the hackers were after me.
To those hackers: waving at you 👋 you almost got me, but not this time.
Linda was someone I really trusted.
Let this be a reminder to everyone:
If someone asks you to download or install something don’t do it!
