We know what you’re waiting for - this isn’t it. Today, we’re back with more tales of our adventures in Kentico’s Xperience CMS. Due to it’s wide usage, the type of solution, and the types of enterprises using this solution - any serious vulnerability, or chain of vulnerabilities to serious impact, is no bueno - and so we have more to tell you about today.
As you may remember from our previous blog post, Kentico’s Xperience CMS product is a CMS solution aimed at enterprises but widely used by o
TL;DR ¶ Exported concrete error types are superior to sentinel errors. They can be more performant, cannot be clobbered, and promote extensibility. Third-party function errutil.Find is a powerful alternative to standard-library function errors.As. Setting the scene ¶ Imagine that you’re writing a package named bluesky whose purpose is to check the availability of usernames on Bluesky, the up-and-coming social-media platform:
package bluesky func IsAvailable(username string) (bool, error) { // actual implementation omitted return false, nil } Calls to IsAvailable may fail (i.

Introduction Many vulnerability writeups nowadays focus on the exploitation process when it comes to software bugs. The term “Exploit Developer” is also still used synonymously with Vulnerability Research, presumably coming from the early 2000s where bugs were easily discoverable and the community was just beginning to explore the art of exploitation. However nowadays with SDL and continuous fuzzing, the discovery of unknown vulnerabilities in crucial systems is getting more important, arguably more than the exploitation process.
A step-by-step guide for open source maintainers on how to handle vulnerability reports confidently from the start.
Why hack one device, when you can hack all of them? By reverse-engineering and finding vulnerabilities in user-machine association flows for smart weighing machines, I was able to take over millions of internet-connected health devices. Hardware and web security are two halves of modern smart device security, and learning to hack both can yield impressive and scary results.
Key Points VanHelsing RaaS In recent weeks, a new and rapidly expanding ransomware-as-a-service (RaaS) program called VanHelsingRaaS has been making waves in the cybercrime world. Launched on March 7, 2025, this service has already demonstrated its rapid growth and deadly potential, having infected three victims within just two weeks of its introduction.

It’s us again!
Once again, we hear the collective groans - but we're back and with yet another merciless pwnage of an inspired and clearly comprehensive RCE solution - no, wait, it's another vuln in yet another backup and replication solution..
While we would enjoy a world in which we could be a little merciful - today we'll explore the painful world of blacklist-based security mechanisms. You can treat this post as a natural continuation of our CVE-2024-40711 writeup, which was written by fel

I recently joined watchTowr, and it is, therefore, time - time for my first watchTowr Labs blogpost, previously teased in a tweet of a pre-auth RCE chain affecting some ‘unknown software’.
Joining the team, I wanted to maintain the trail of destruction left by the watchTowr Labs team, and so had to get my teeth into things quickly.
Two primary goals were clear:
1. Look at something completely new - I quickly realized that I've never looked at any CMS solution, and so could be a fun good star
STAR Labs Windows Exploitation Challenge Writeup Over the past few months, the STAR Labs team has been hosting a Windows exploitation challenge. I was lucky enough to solve it and got myself a ticket to Off-By-One conference. Here is my writeup for the challenge!
Analyzing the binary We are given a Windows kernel driver. Basic analysis shows that it is used to receive and save messages sent from usermode.
Important structures There are two key structures used in this driver: handle and message entry.

TL;DR ¶ In this post, I discuss the cost of Go’s panic and recover functions through a programme adapted from Joshua Bloch’s Effective Java book.
Abusing Java exceptions for control flow ¶ Even though my Java days are long gone and Go has been my language of predilection for a while, I still occasionally revisit Effective Java, Joshua Bloch’s seminal and award-winning book, and I never fail to rediscover nuggets of wisdom in it.
Research by: Itay Cohen (@megabeets_) Over the past few decades, hacktivism has been, in a lot of cases, characterized by minor website defacements and distributed denial-of-service (DDoS) attacks, which, while making headlines, had minimal lasting impact. However, in recent years, we have observed a significant shift in the nature of these activities. Groups that appear to […]

As an industry, we believe that we’ve come to a common consensus after 25 years of circular debates - disclosure is terrible, information is actually dangerous, it’s best that it’s not shared, and the only way to really to ensure that no one ever uses information in a way that you don’t like (this part is key) is to make up terms for your way of doing things.
We have actively petitioned vendors to be more transparent, and we’re currently investing a lot of R&D time in the development of the bes
