Ransomware Groups Return with a Vengeance in November, Reaching Record-High Number of Victims

November witnessed a resurgence of ransomware groups, resulting in a record-high number of victims. The increase in ransomware attacks, coupled with the effectiveness of LockBit and the exploitation of the CitrixBleed vulnerability, highlights the urgent need for strengthened cybersecurity measures. While predictions indicate a temporary decrease in January, the unpredictable nature of these attacks necessitates constant vigilance. The persistent threat of ransomware reinforces the ongoing importance of proactive cybersecurity practices to protect organizations and individuals from potential devastation.

In the month of November, ransomware groups reemerged with a significant increase in their activities, resulting in the highest number of listed victims ever recorded. This resurgence raised concerns among cybersecurity experts and highlighted the ongoing threat posed by ransomware attacks.

Increase in ransomware victims

The month of November saw a staggering 39.08% increase in ransomware victims compared to October. Moreover, when compared to the same period in the previous year, there was a striking 110.43% surge. Disturbingly, this marked the eleventh consecutive month with a year-on-year increase in ransomware victims and the ninth consecutive month with victim counts surpassing 300. These alarming statistics indicate a concerning escalation in ransomware attacks.

LockBit’s impact

For the notorious LockBit ransomware group, November turned out to be one of their most devastating months in 2023. With a significant number of listed victims, November ranked as LockBit’s third-highest month of the year in terms of successful attacks. This highlights the effectiveness and reach of LockBit’s operations, underscoring the urgency to counter and neutralize such threats.

Citrix Bleed Vulnerability

One significant factor contributing to the surge in ransomware attacks in November is the exploitation of the CitrixBleed vulnerability. This vulnerability has reportedly become a new staple for ransomware groups, allowing them to exploit weaknesses in Citrix systems and gain unauthorized access. The widespread adoption of this technique led to an increase in successful attacks and subsequent victim listings during the month.

Predictions for December

Looking ahead, the Corvus Threat Intel team anticipates an even higher number of ransomware leak site victims to be listed in December compared to the same period in 2021. This prediction raises concerns about the escalating nature of ransomware attacks and reinforces the need for proactive measures to enhance cybersecurity defenses.

Temporary decrease in January

While the trend of increasing ransomware attacks is expected to continue, experts predict a temporary decrease in January. This decline is attributed to the holiday season, during which ransomware attackers may take some time off. However, it is crucial not to let our guard down, as the threat can resurface at any time.

Impact of QakBot Takedown

The takedown of the QakBot malware loader had a substantial impact on various ransomware groups. However, the resurgence in victim listings during November indicates that the ransomware ecosystem has successfully pivoted away from QBot. This adaptability demonstrates the sophistication and resilience of these malicious actors, making it imperative to remain vigilant against evolving threats.

Uncertainties in predictions

It is important to acknowledge that the return of QakBot, which is being observed by cybersecurity firms, could potentially influence Corvus’ predictions for the near future. The reappearance of this malware loader emphasizes the dynamic and constantly evolving nature of ransomware attacks, necessitating continuous monitoring and adaptation of defense strategies.

Highlighting the ongoing threat

The significant increase in new ransomware victims during November serves as a stark reminder of the ongoing threat posed by these malicious actors. It underscores the critical need for robust cybersecurity measures to safeguard organizations and individuals against these attacks. Implementing multifaceted security strategies, including regular software updates, robust firewalls, strong password policies, employee training, and secure backups, is crucial in mitigating the risks associated with ransomware.
