Vulnerabilities Year-in-Review: 2023
In 2023, threat actors continued to exploit a variety of vulnerabilities — both newly discovered weaknesses and unresolved issues — to carry out sophisticated attacks on global organizations. The number of documented software vulnerabilities continued to rise, and threat actors were quick to capitalize on new vulnerabilities and leverage recent releases of publicly available vulnerability research and exploit code to target entities. However, while there was a high number of vulnerabilities released in the reporting period, only a handful actually were weaponized in attacks. The ones of most interest are those that threat actors use for exploitation. In this report, we’ll analyze the numbers and types of vulnerabilities in 2023 with a view to understanding attack trends and how organizations can better defend themselves.
State of WordPress Security In 2024
This year, we’ve partnered with Sucuri. With both of our data combined, we can cover the entire timeline of security incidents from the vulnerability being found to the point where malware infection gets detected on a vulnerable website. 2023 was another record year of new vulnerabilities being discovered and fixed in the WordPress ecosystem. In 2023, we added 5,948 new vulnerabilities to the Patchstack vulnerability database. That’s 24% more than in 2022.

Check if you're vulnerable to CVE-2024-3094
CVE-2024-3094 is the new hot one and it’s extremely critical; however, impact should be limited as most normal linux distros are unaffected. Here’s some stuff to know:
xz-utils backdoor situation
This is still a new situation. There is a lot we don't know. We don't know if there are more possible exploit paths. We only know about this one path. Please update your systems regardless. Unknown unknowns are safer than known unknowns. This is a living document. Everything in this document is made in good faith of being accurate, but like I just said; we don't know much about what's going on.
xz/liblzma: Bash-stage Obfuscation Explained - gynvael.coldwind//vx.log
esterday Andres Freund emailed oss-security@ informing the community of the discovery of a backdoor in xz/liblzma, which affected OpenSSH server (huge respect for noticing and investigating this). Andres' email is an amazing summary of the whole drama, so I'll skip that. While admittedly most juicy and interesting part is the obfuscated binary with the backdoor, the part that caught my attention – and what this blogpost is about – is the initial part in bash and the simple-but-clever obfuscation methods used there. Note that this isn't a full description of what the bash stages do, but rather a write down of how each stage is obfuscated and extracted.
From OneNote to RansomNote: An Ice Cold Intrusion - The DFIR Report
- In late February 2023, threat actors rode a wave of initial access using Microsoft OneNote files. In this case, we observed a threat actor deliver IcedID using this method. After loading IcedID and establishing persistence, there was no further actions, other than beaconing for over 30 days. The threat actor used Cobalt Strike and AnyDesk to target a file server and a backup server. * The threat actor used FileZilla to exfiltrate data from the network before deploying Nokoyawa ransomware.

Key Lesson from Microsoft's Password Spray Hack: Secure Every Account
In January 2024, Microsoft discovered they'd been the victim of a hack orchestrated by Russian-state hackers Midnight Blizzard (sometimes known as Nobelium). The concerning detail about this case is how easy it was to breach the software giant. It wasn't a highly technical hack that exploited a zero-day vulnerability – the hackers used a simple password spray attack to take control of an old, inactive account. This serves as a stark reminder of the importance of password security and why organizations need to protect every user account.
