On March 12, 2026, Veeam released fixes for multiple high and critical severity vulnerabilities in their Backup & Replication product that could allow remote code execution (RCE), privilege escalation, and credential theft. Arctic Wolf has not identified publicly available proof-of-concept exploits for these vulnerabilities, nor have we observed any exploitation.

On March 4, 2026, Cisco released fixes for two maximum-severity vulnerabilities impacting Cisco Secure Firewall Management Center (FMC), which is used to centrally manage Cisco Secure Firewall devices. Arctic Wolf has not observed threat actors exploiting these vulnerabilities, nor have any public proof-of-concept exploits been reported.

On March 03, 2026, pac4j released fixes for a maximum severity vulnerability in pac4j-jwt, tracked as CVE-2026-29000. The flaw arises from improper verification of cryptographic signatures in the JwtAuthenticator component when processing encrypted JWTs (JWE). A remote, unauthenticated threat actor who knows the server’s RSA public key can bypass authentication and impersonate arbitrary users (including administrators) by submitting a crafted JWE whose inner token is an unsigned PlainJWT.

Between January 2025 and January 2026, Arctic Wolf tracked an extensive cyber espionage campaign that we assess was conducted by SloppyLemming (also known as Outrider Tiger and Fishing Elephant), an India-nexus threat actor, targeting government entities and critical infrastructure operators in Pakistan and Bangladesh.

On February 28, 2026, the United States, in coordination with Israel, launched a large-scale military campaign against Iran known as Operation Epic Fury, marking a significant escalation in direct hostilities. The operation involved coordinated air, missile, naval, and cyber strikes targeting Iranian military and nuclear facilities across the country. Iran retaliated with ballistic missile and drone strikes targeting Israeli territory and U.S.

The modern threat landscape is an ever-evolving battlefield of innovation and escalation. Thanks to the rapid adoption of artificial intelligence, both attackers and defenders now have powerful new tools at their disposal. But who has the edge when it comes to the artificial intelligence (AI) arms race? Unsurprisingly, the answer is complicated.

On February 24, 2026, sooperset, the mcp-atlassian project maintainer, released fixes for a critical vulnerability in mcp-atlassian, tracked as CVE-2026-27825. The flaw arises from missing directory confinement and inadequate path traversal validation in the Confluence attachment download tools which could allow a remote (network-adjacent), unauthenticated threat actor to write files to arbitrary paths, enabling local privilege escalation and remote code execution.

At Arctic Wolf, we believe the future of cybersecurity is built on AI guided by human expertise. Staying at the forefront of security operations means not just adopting new technology but deeply understanding how and where it should be applied.

On February 25, 2026, Cisco released fixes for a maximum severity authentication bypass vulnerability in Cisco Catalyst SD-WAN Controller (formerly vSmart) and Cisco Catalyst SD-WAN Manager (formerly vManage), tracked as CVE-2026-20127. The flaw arises from a broken peering authentication mechanism in the control-plane authentication workflow. This vulnerability potentially allows a remote, unauthenticated threat actor to bypass authentication and obtain administrative privileges on an affected system.
