During this period, over 343 million attacks were blocked, with Web Anti-Virus responding to 50 million unique links and File Anti-Virus blocking nearly 15 million malicious objects. A significant development was the disruption of the RAMP cybercrime forum by law enforcement, impacting the ransomware-as-a-service (RaaS) ecosystem. The Interlock group exploited CVE-2026-20131, a zero-day vulnerability in Cisco Secure FMC firewalls, demonstrating the continued reliance on zero-days for initial access. Clop ransomware emerged as the most prolific, followed by Qilin and a newcomer, The Gentlemen. Additionally, Kaspersky solutions detected 2938 new ransomware variants and protected 77,319 unique users from ransomware attacks, while over 260,000 users were targeted by miners.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003e\u003cstrong\u003eInitial Access (CVE-2026-20131):\u003c/strong\u003e The Interlock group exploits CVE-2026-20131, a zero-day vulnerability in Cisco Secure FMC firewall management software, to gain initial access with root privileges.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eCode Execution:\u003c/strong\u003e Exploiting the vulnerability enables arbitrary Java code execution on the affected Cisco Secure FMC device.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003ePrivilege Escalation:\u003c/strong\u003e The attacker leverages root privileges gained from the exploit to perform privileged operations.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eRansomware Deployment:\u003c/strong\u003e The attackers deploy ransomware payloads after gaining access to the system, potentially leveraging the access gained through the firewall to reach internal network resources.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eData Encryption:\u003c/strong\u003e The ransomware encrypts critical files and data on the compromised systems, rendering them inaccessible to the users.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eRansom Demand:\u003c/strong\u003e A ransom note is generated, demanding payment in exchange for decryption keys.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eData Leak Site Publication:\u003c/strong\u003e If the ransom is not paid, the attackers threaten to publish or leak stolen data on their data leak site (DLS).\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eThe report indicates that 77,319 unique users were attacked by ransomware Trojans in Q1 2026.
