FortiGuard Center Outbreak Alerts

FortiGuard Labs continue to observe detections in the wild related to the Akira ransomware group. According to the new report by CISA it has targeted over 250 organizations since the past year, affecting numerous businesses and critical infrastructure entities across North America, Europe, and Australia. The gang has made over $42 million from the attacks as ransom payments.

Actively exploited as a zero-day in data theft and extortion campaigns, with activity linked to the Cl0p ransomware group. Successful exploitation enables complete takeover of Oracle Concurrent Processing, opening the door to lateral movement, sensitive data exfiltration, and potential ransomware deployment.

A critical deserialization vulnerability in GoAnywhere MFT’s License Servlet (CVSS 10.0) is actively being exploited in the wild. The flaw allows attackers with a forged license response signature to deserialize arbitrary objects, which can lead to command injection and remote code execution (RCE). FortiGuard telemetry shows sustained, high-volume exploitation attempts against GoAnywhere MFT instances.

FortiGuard Labs’ network telemetry has observed active exploitation of known vulnerabilities in Drupal Core and the WP-Automatic WordPress plugin for initial access. Following compromise, attackers deploy multiple web shells and utilities to enable lateral movement, privilege escalation, and the installation of remote access trojans (RATs).

FortiGuard Labs has observed a sharp increase in exploitation attempts targeting the ‘Citrix Bleed 2’ vulnerability since July 28, 2025. Telemetry indicates activity has surged to over 6,000 detections across IPS sensors globally. The majority of observed attacks are concentrated in the United States, Australia, Germany, and the United Kingdom, with adversaries primarily focusing on high-value sectors such as technology, banking, healthcare, and education.

FortiGuard Labs has detected and successfully blocked hundreds of exploitation attempts targeting a newly discovered zero-day vulnerability chain in on-premises Microsoft SharePoint servers. This active campaign is being exploited by multiple threat actors and poses a significant risk to a wide range of sectors including government, education, healthcare, and large enterprises.

A campaign targeting SonicWall SMA 100 series appliances is currently under active exploitation, leveraging both known vulnerabilities and potential zero-days to gain persistent access to enterprise networks. The threat actors deploy a custom Linux-based rootkit for stealth and long-term persistence.

FortiGuard Labs has observed a significant uptick in attacks targeting Langflow, leveraging a recently discovered authentication bypass vulnerability that allows unauthenticated remote attackers to fully compromise affected servers.

Threat Actors are actively exploiting CVE-2024-3721, a command injection vulnerability in TBK DVR devices (Digital Video Recorders). This flaw allows unauthenticated remote code execution (RCE) via crafted HTTP requests to the endpoint. The compromised devices are conscripted into a botnet capable of conducting DDoS attacks.

FortiGuard Labs continues to observe ongoing attack attempts targeting SimpleHelp, a Remote Monitoring and Management (RMM) software, due to a critical unauthenticated path traversal vulnerability (CVE-2024-57727) affecting versions 5.5.7 and earlier.
