Executive Summary On December 13, 2023, Lumen’s Black Lotus Labs reported our findings on the KV-botnet, a covert data transfer network used by state-sponsored actors based in China to conduct espionage and intelligence activities targeting U.S. critical infrastructure. Around the time of the first publication, we identified a spike in activity that we assess aligns
In 2023, ransomware actors intensified their operations, targeting high-profile institutions and critical infrastructure, including hospitals, schools, and government agencies. Major ransomware supply chain attacks were carried out exploiting the ubiquitous file transfer software MOVEit, impacting companies ranging from the BBC to British Airways. As a result of these attacks and others, ransomware gangs reached an unprecedented milestone, surpassing $1 billion in extorted cryptocurrency payments from victims.
Last year’s developments highlight the evolving nature of this cyber threat and its increasing impact on global institutions and security at large.
The Qualys Threat Research Unit (TRU) has recently unearthed four significant vulnerabilities in the GNU C Library, a cornerstone for countless applications in the Linux environment.
Before diving into the specific details of the vulnerabilities discovered by the Qualys Threat Research Unit in the GNU C Library, it’s crucial to understand these findings’ broader impact and importance. The GNU C Library, or glibc, is an essential component of virtually every Linux-based system, serving as the core interface between applications and the Linux kernel. The recent discovery of these vulnerabilities is not just a technical concern but a matter of widespread security implications.

Q2 2023 saw an unprecedented escalation in DDoS attack sophistication. Pro-Russian hacktivists REvil, Killnet and Anonymous Sudan joined forces to attack Western sites. Mitel vulnerability exploits surged by a whopping 532%, and attacks on crypto rocketed up by 600%. Read the full story...
In a recent investigation by Microsoft Incident Response of a BlackByte 2.0 ransomware attack, we found that the threat actor progressed through the full attack chain, from initial access to impact, in less than five days, causing significant business disruption for the victim organization.
We found that malicious actors used malvertising to distribute malware via cloned webpages of legitimate organizations. The distribution involved a webpage of the well-known application WinSCP, an open-source Windows application for file transfer. We were able to identify that this activity led to a BlackCat (aka ALPHV) infection, and actors also used SpyBoy, a terminator that tampers with protection provided by agents.
We found TrafficStealer abusing open container APIs in order to redirect traffic to specific websites and manipulate engagement with ads.
The Vice Society ransomware gang exfiltrated victim network data using a custom Microsoft PowerShell script. We dissect how each function of it works.
We detected Mac malware MacStealer spreading via websites, social media, and messaging platforms Twitter, Discord, and Telegram. Cybercriminals lure victims to download it by plagiarizing legitimate play-to-earn (P2E) apps’ images and offering jobs as beta testers.
