As we enter the second quarter of 2026, Kaspersky's telemetry—based on users who consented to share statistical data—reveals a threat landscape dominated by relentless ransomware campaigns, law enforcement crackdowns, and the exploitation of critical vulnerabilities. The first three months of the year saw over 343 million online attacks blocked, alongside significant disruptions in the ransomware ecosystem. This article distills the most important statistics, incidents, and shifts from Q1 2026 into a listicle that every security professional should understand. From new ransomware variants to the takedown of a major cybercrime forum, here are the seven things you need to know.
1. Attack Volumes Reach New Heights
Kaspersky products blocked more than 343 million attacks originating from online resources in Q1 2026. Web Anti-Virus responded to 50 million unique links, and File Anti-Virus prevented nearly 15 million malicious or potentially unwanted objects from executing. These numbers highlight the sheer scale of threats users face daily. The increase in blocked attacks suggests adversaries are ramping up distribution efforts through compromised websites, phishing campaigns, and malvertising. Organizations must ensure their web filtering and endpoint protection are up to date, as even a single successful link click can lead to devastating breaches. The 50 million unique links further indicate a diversified attack surface where threat actors continuously rotate infrastructure to evade blacklists.
2. Ransomware Variants and Victim Counts Climb
In Q1 2026, Kaspersky detected 2,938 new ransomware variants. More than 77,000 users experienced ransomware attacks, with 14% of all victims whose data appeared on data leak sites (DLS) being attributed to the Clop group. The sheer volume of new variants underscores how quickly ransomware-as-a-service (RaaS) groups iterate to bypass signature-based detection. The high number of unique victims—77,000—emphasizes that ransomware remains a mass-market threat, not just a targeted one. Clop's dominance in DLS leaks (14% share) signals its sophisticated data-theft extortion model. Defenders should prioritize backup strategies, network segmentation, and user education to mitigate the risk of encryption and data exposure.
3. Cryptominers Continue to Target Over 260,000 Users
Beyond ransomware, cryptomining malware remained a persistent nuisance, with more than 260,000 users targeted by miners in Q1 2026. While not as destructive as ransomware, cryptominers can degrade system performance, increase electricity costs, and serve as an early indicator of broader compromise. The sustained targeting of users suggests that cybercriminals still find financial value in hijacking CPU/GPU resources, especially as cryptocurrency prices fluctuate. Organizations should monitor for unusual resource usage and block unauthorized cryptocurrency mining scripts at the network level.
4. Law Enforcement Strikes Back: RAMP Forum Seized
In January 2026, the FBI allegedly seized domains belonging to the RAMP cybercrime forum, a major platform used by ransomware developers to advertise RaaS programs and recruit affiliates. While no official FBI statement was released, a RAMP moderator confirmed that law enforcement had gained control over the forum. The takedown disrupted a key element of the RaaS ecosystem, creating ripple effects for operators, affiliates, and initial access brokers. This action demonstrates that international law enforcement is increasingly targeting the infrastructure that enables ransomware attacks. Prosecutions of individuals also intensified.
5. Prosecutions Target Individuals Across the Ransomware Chain
Several high-profile arrests and convictions occurred in early 2026. A man suspected of links to the Phobos group was arrested in Poland for creating and distributing tools used to unlawfully obtain information. In March, a Phobos ransomware administrator pleaded guilty to developing the Trojan that had been used in attacks since at least November 2020. Separately, the U.S. Department of Justice charged a ransomware negotiator—an employee of a cyberincident investigation firm—for allegedly colluding with the BlackCat threat actor and sharing privileged negotiation insights. Additionally, a U.S. court sentenced an initial access broker associated with Yanluowang to 81 months in prison, with losses exceeding $9 million actual and $24 million intended. These cases show prosecutors are pursuing not only the ransomware developers but also intermediaries and affiliates.
6. Zero-Day Vulnerability Exploited: CVE-2026-20131
The Interlock ransomware group heavily exploited the CVE-2026-20131 zero-day vulnerability in Cisco Secure FMC firewall management software during Q1 2026. This flaw allowed attackers to gain initial access to networks, then deploy ransomware. The exploitation underscores the importance of patch management—even for critical infrastructure like firewall appliances. Organizations using Cisco Secure FMC should immediately apply any available patches or workarounds. The Interlock group's use of a zero-day in a widely deployed management console suggests they are investing in sophisticated exploitation capabilities.
7. RaaS Ecosystem Disruption Creates Challenges and Opportunities
The takedown of the RAMP forum, combined with arrests and convictions, has significantly disrupted the ransomware-as-a-service ecosystem. RAMP served as a marketplace for initial access and RaaS recruitment; its seizure makes it harder for new affiliates to find profitable groups. However, history shows that such disruptions often lead to splinter groups and the emergence of new, more aggressive actors. Defenders should anticipate a temporary decrease in volume followed by a shift in tactics. Continuous monitoring of underground forums and intelligence sharing remain critical to staying ahead of the evolving threat.
In conclusion, Q1 2026 demonstrated that while law enforcement is making strides against ransomware infrastructure and key individuals, the threat landscape remains dynamic and dangerous. Organizations must maintain robust defenses, patch vulnerabilities promptly, and educate users to mitigate the risks highlighted by these statistics. The coming quarters will likely see further evolution, with cybercriminals adapting to enforcement pressure.
