Introducing Sulla: Praetorian's Open-Source SMB Secret Scanner
In June 2026, Praetorian released Sulla, an open-source tool designed to scan SMB shares for exposed credentials across enterprise networks. Sulla automates the discovery of readable SMB shares, traverses their file structures, and scans contents for sensitive information using the Titus detection library. This tool addresses the challenge of manually reviewing numerous network shares, which is often tedious and inefficient. By integrating Sulla into their Continuous Threat Exposure Management platform, Guard, Praetorian ensures that SMB secrets are identified promptly as they appear in environments. The release of Sulla highlights the growing need for automated tools to detect and mitigate the risks associated with exposed credentials in network shares. As organizations increasingly rely on complex network infrastructures, tools like Sulla become essential in proactively identifying and addressing security vulnerabilities, thereby enhancing overall cybersecurity posture.

Critical Vulnerability in SolarWinds Serv-U: CVE-2026-28318
In early June 2026, a high-severity vulnerability (CVE-2026-28318) was identified in SolarWinds Serv-U, a widely used file transfer server. This flaw allows unauthenticated attackers to crash the Serv-U service by sending specially crafted POST requests with the 'Content-Encoding: deflate' header, leading to a denial-of-service (DoS) condition. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) confirmed active exploitation of this vulnerability and added it to their Known Exploited Vulnerabilities catalog on June 5, 2026. Organizations are urged to apply the available patch or implement recommended mitigations promptly to prevent service disruptions. ([helpnetsecurity.com](https://www.helpnetsecurity.com/2026/06/08/cisa-patch-actively-exploited-solarwinds-serv-u-dos-vulnerability-cve-2026-28318/?utm_source=openai)) The exploitation of CVE-2026-28318 underscores the persistent targeting of file transfer services by threat actors.

DragonForce Ransomware's Innovative Exploitation of Microsoft Teams in 2025
In December 2025, the DragonForce ransomware group executed a sophisticated attack against a major U.S. services company. They exploited an unknown vulnerability in an SQL or MSSQL server to gain initial access. Subsequently, they deployed a custom Go-based malware named 'Backdoor.Turn,' which abused Microsoft Teams' Traversal Using Relays around NAT (TURN) protocol to conceal command-and-control (C2) communications within legitimate Teams traffic. This allowed the attackers to evade detection while exfiltrating data and deploying ransomware to encrypt the victim's systems. This incident underscores a concerning trend where threat actors leverage trusted cloud-based collaboration platforms to mask malicious activities. The abuse of Microsoft Teams' infrastructure for C2 communications highlights the need for organizations to scrutinize even legitimate traffic and implement robust monitoring mechanisms to detect anomalies within trusted services.

Fortinet FortiSandbox Vulnerabilities Under Active Exploitation
In June 2026, multiple critical vulnerabilities in Fortinet's FortiSandbox platform—specifically CVE-2026-39813, CVE-2026-39808, and CVE-2026-25089—were actively exploited by threat actors. These flaws allowed unauthenticated attackers to escalate privileges and execute unauthorized code remotely through low-complexity command injection attacks that required no user interaction. Fortinet had released patches for these vulnerabilities in April 2026, but unpatched systems remained at significant risk. The exploitation of these vulnerabilities underscores the persistent targeting of security appliances by cyber adversaries. Organizations relying on FortiSandbox for threat detection must ensure timely application of security updates to mitigate potential breaches and maintain the integrity of their security infrastructure.

GhostTree Attack: Exploiting NTFS Junctions to Evade Detection
In May 2026, Varonis Threat Labs identified a novel evasion technique named 'GhostTree' that exploits NTFS junctions in Windows systems. By creating recursive directory loops, attackers can generate an effectively infinite number of file paths, causing Endpoint Detection and Response (EDR) tools to hang during recursive scans. This manipulation allows malicious files to remain undetected, as the scanning process becomes trapped in the loop and fails to complete. The technique requires only standard user permissions, making it accessible without administrative rights. ([varonis.com](https://www.varonis.com/blog/ghosttree-ntfs-trick?utm_source=openai)) The discovery of GhostTree underscores the evolving sophistication of malware evasion tactics. As attackers increasingly exploit legitimate system features to bypass security measures, organizations must enhance their detection capabilities and adopt comprehensive monitoring strategies to identify and mitigate such advanced threats.

Malicious JetBrains Plugins Compromise Developer API Keys
In June 2026, Aikido Security uncovered a coordinated malware campaign involving at least 15 malicious plugins on the JetBrains Marketplace. These plugins, masquerading as AI coding assistants and Git utilities, were designed to steal AI API keys from developers. Upon users entering their API keys and clicking 'Apply,' the credentials were transmitted to a hardcoded server controlled by the attackers. The plugins, published under seven vendor accounts since October 2025, amassed nearly 70,000 installations. Notably, some plugins offered a paid tier, potentially redistributing stolen API keys to paying users. This incident underscores the escalating threat of supply chain attacks targeting developer ecosystems. As AI-powered tools become integral to software development, malicious actors are increasingly exploiting trusted platforms to distribute credential-stealing malware, highlighting the need for enhanced vigilance and security measures within developer communities.

Malware Campaign Targets Steam Users via Wallpaper Engine
In June 2026, cybersecurity researchers uncovered a campaign where threat actors exploited Steam Workshop and the Wallpaper Engine application to distribute malware. Malicious actors uploaded infected wallpaper packages to Steam Workshop, which, when installed via Wallpaper Engine, executed payloads leading to Steam account hijacking, system backdoors, or cryptomining operations. This campaign primarily targeted users in China and Russia but also affected individuals in Singapore, Hong Kong, Germany, Vietnam, India, and Canada. The malware was often concealed within password-protected archives or bundled directly in the wallpaper packages, executing automatically upon installation. This incident underscores the evolving tactics of cybercriminals who leverage trusted platforms and user-generated content to disseminate malware. The exploitation of application wallpapers highlights the need for enhanced scrutiny of community-driven content and the importance of robust security measures to detect and prevent such sophisticated attacks.

Rokarolla Android Malware: A New Threat to Mobile Banking Security
In June 2026, a sophisticated Android banking Trojan named Rokarolla emerged, targeting 217 banking and cryptocurrency applications. Distributed through malicious websites masquerading as legitimate Google Chrome or TikTok apps, Rokarolla gains complete administrative control over infected devices. Its capabilities include stealing lock screen credentials, contact lists, SMS data, and continuously recording user input via keyloggers. The malware employs overlays to display fake login screens, capturing sensitive financial information when users access targeted applications. Additionally, Rokarolla disables Google Play Protect, hides its icon, and maintains persistence by preventing device sleep, thereby evading detection and removal. The emergence of Rokarolla underscores a significant evolution in Android malware, combining financial data theft with extensive device surveillance and control. This trend highlights the increasing sophistication of threat actors and the urgent need for enhanced mobile security measures to protect sensitive user information and maintain device integrity.
