NSO Group has been acquired by U.S. investors, ending Israeli control

NSO Group is the company that develops every smart phone's nightmare Pegasus, the know Spyware

In my opinion it will still be used by Americans and Israelis for the same reasons they used before or the Israelis are developing something new

After AWS outage problem many signs are saying that Azure is down in many places of the world, here in Egypt many people/companies claim that they are suffering with Azure services or they can't reach it

There is an opinion says all tech companies should think again about the infrastructure they are based on or they are providing with, and I go with this opinion

Btw, this meme is going viral saying that the next turn will be for GCP or Google's cloud

If you are managing to do a cert in cyber security specially like OSCP, then Linux privilege escalation is a crucial skill you have to learn. I found this flow diagram is a great one to follow during your hunting for privilege escalation


a great way as well to do a basic enumeration using automated tools like:
1- linPEAS
https://github.com/peass-ng/PEASS-ng/tree/master/linPEAS
2- LinEnum
https://github.com/rebootuser/LinEnum
3- Linux Exploit Suggester

➜ finally keep your notes updated and up to date 😉

CharlotteOS - Catten
catten is an operating system kernel developed as a key component of the CharlotteOS project but it is designed to be flexible enough that we hope it can also find use in many other places.

So we have a kernel built in rust, I heard that Ubuntu are willing to do the same. Seems there are no more buffer over flows 👀

What do you see about this share us in comments 👇

Balancer Protocol (web3 Ethereum DeFi Protocol) got hacked due to a bug in their code allows attackers to steal +70M $ or 110M $ (as some news says) which is the biggest breach in the world till now

▲In my point of view (or a security researcher point of view), code reviewing -by security experts not for regular code bugs but for vulnerabilities- isn't a critical step to take nowadays not just a routine also internal pentesting -not for one time- is another crucial step to do

ⓘ The obvious classification of this vulnerability is A01:2021-Broken Access Control which is already categorized in OWASP top 10 as a growing issue

OWASP TOP 10
The new release 2025

If you don't know what is owasp top 10 then let's explain it, owasp is a foundation aims to help security researchers and companies/organizations to secure their products also to help devs to write a secure code to avoid vulnerable codes. Owasp also provides with some learning materials as the challenges we solved before here for android also they have a vulnerable web app called juice shop to learn web vulnerabilities. The owasp top 10 is a list published by owasp.org every few years about the most found vulnerabilities by security researchers during that period
