Global Ransomware Surge
Ransomware activity soared in Q4 2024, setting a record with 1,663 victims posted on leak sites, according to the Corvus/Travelers Q4 2024 Cyber Threat Report. That is a 32% jump from Q3, which marks the highest quarterly total they’ve ever recorded. November led the charge with 629 incidents before a drop to 516 in December. This end-of-year cybercrime spike reflects a recurring pattern, and that isn’t cybercriminals needing to meet some year-end quota. Hackers exploit holiday season vulnerabilities, which, summed up simply, is us distracted, thinking about the holidays.
In total, 2024 saw 5,243 leak-site victims—a 15% rise over 2023. But in this case, more resulted in less. Here’s how. Despite the surge, ransom payments dropped to $813 million, down 35% from the prior year. Experts report companies are resisting demands. Instead, they are opting to absorb disruption. Still, stolen data appeared in 87.6% of claims filed, underlining persistent business risk.
A Shift Toward Scalable, Repeatable Attacks
In 2023, zero-day vulnerabilities wrought havoc. Ransomware Q4 2024 campaigns took a more methodical route. Hackers focused on reusable attack vectors like weak VPN credentials. A leaked 2023 playbook encouraged targeting default usernames and common passwords over novel software flaws.
This approach enables broad, fast deployment—less scavenging, more hunting. The pivot helped threat actors scale up operations without needing significant vulnerability discoveries—many leveraged credentials lacking multi-factor authentication (MFA), sidestepping even advanced network defenses.
Nation-States Aid and Abet Ransomware Growth
State-backed cybercriminals no longer stick to espionage. Groups like Pioneer Kitten and Jumpy Pisces (hat-tip to the names) reportedly support ransomware gangs. Some provide access to networks, and others assist with encryption.
Google and OpenAI were identified as aiding these operations. AI is used for phishing and reconnaissance, marking a new era of cyber-sophistication. Yet, oddly, most mainstream ransomware groups remain slow to adopt AI for actual code development.
New Faces, Old Tactics: The 2024 Ransomware Cast
RansomHub led the Q4 threat landscape with 238 incidents. Akira and PLAY followed closely, contributing 133 and 95 attacks, respectively. New entrants like Kill Security, Fog, and FunkSec also emerged.
FunkSec stood out for all the wrong reasons. Researchers question the group’s tech skills and accuse it of recycling data. Some suspect it’s using AI to inflate its presence rather than build real tools. Still, its rapid rise illustrates how low the barrier to entry has become.
Law enforcement takedowns of RaaS giants like LockBit and AlphVM reshaped the ecosystem. This opened the floodgates for new groups—55 appeared in 2024 alone, a 67% increase from the previous year.
Industries in the Crosshairs
Consulting and IT service firms became top ransomware targets of cybercriminals. This is most likely because they have access to multiple company networks. Construction saw a 56% spike in attacks, logging 129 in Q4. Healthcare incidents also rose from 166 in 2023 to 210 in 2024. Law firms and financial service providers rounded out the high-risk list.
Government agencies experienced late-year surges, showing no sector is immune. These patterns highlight how attackers seek industries where disruption ripples widely.
Cyber Defense: Recommendations for Resilience
With the data on ransomware Q4 2024, experts urge firms to adopt phishing-resistant MFA, particularly for remote access and email, to guard against cybercrime. Patch VPNs and edge devices promptly. Maintain reliable backups and test disaster recovery plans. Deploy EDR solutions with round-the-clock monitoring.
Ransomware won’t disappear. However, organizations can raise the bar high enough to deter cybercriminals. The tools exist. The urgency is real.

Everyday Analogy for General Audience
Imagine burglars overrun your neighborhood. But instead of breaking windows, they learn every unlocked door. That’s ransomware in 2024. Hackers stopped chasing rare exploits and started using a master key made of weak passwords and missing MFA. It’s like a thief with a map of homes that forgot to lock up. In this cyber era, your digital locks must evolve. Today’s crooks aren’t just smarter—they’re scalable. Like fast food franchises, they’re multiplying.
