Fast Facts Researchers discovered “DeepLoad,” a malware strain capable of stealing browser credentials and live keystrokes immediately after infection, using AI-generated code and process injection to evade detection. DeepLoad employs social engineering through “ClickFix” prompts, creating persistent scheduled tasks and using legitimate Windows tools to silently maintain access even after initial cleanup. The malware’s heavily obfuscated, AI-generated loader disguises its malicious payload, which injects into a trusted Windows process, complicating detection efforts. Standard cleanup methods are insufficient; organizations must audit WMI subscriptions, enable advanced logging, and change all credentials to fully remediate DeepLoad infections due to its persistent, evolving mechanisms.…

Fast Facts A misconfigured Russian-hosted server exposed the complete operational toolkit of TheGentlemen ransomware affiliates, including victim credentials, plaintext tokens, and deployment scripts, revealing active and past attacks. The server contained a comprehensive batch script, z1.bat, which rapidly disables security measures, stops critical enterprise services, clears logs, and sets up persistent backdoors (e.g., Sticky Keys exploit, RDP unsecurity). The attack toolkit demonstrated sophisticated pre-encryption steps designed to maximize victim impact, including disabling antivirus, deleting shadow copies, creating network shares, and establishing hidden remote access tunnels through ngrok. Security analysts recommend monitoring for specific behaviors (service disablements, log clearing, Mimikatz activity,…

Top Highlights Iranian cyber actors are expanding their tactics by using messaging platforms like Telegram as command-and-control channels to deliver malware, blending social engineering with covert communication to evade detection. The malware campaign targets dissidents, journalists, and individuals opposing Iran, using tailored social engineering tactics to infect devices and maintain persistent access through multi-stage payloads. Threat actors leverage legitimate apps and Telegram bots to exfiltrate data, including screen captures and files, while employing evasion techniques such as registry modifications and PowerShell to avoid detection. The FBI stresses the importance of enhanced monitoring, strong authentication, regular updates, and cautious online behavior…

Fast Facts A cybercrime group called TeamPCP has been secretly exploiting cloud vulnerabilities since late 2025 using its canister-based blockchain infrastructure to automate wide-scale attacks on Azure and AWS environments, primarily targeting Docker, Kubernetes, Redis, and known flaws like React2Shell. Their self-propagating worm, CanisterWorm, moves laterally within networks to steal credentials and extort victims via Telegram, with over 97% of compromised systems located on Azure and AWS. In March 2026, TeamPCP escalated by injecting malware into Trivy’s GitHub releases, stealing sensitive credentials, and deploying a geo-targeted wiper that destroys data on Iranian systems or those with Farsi settings, indicating political…

Top Highlights Secrets sprawl is accelerating rapidly, with a 34% increase in 2025 and AI tools driving 81% more leaks, expanding the attack surface. Internal repositories and collaboration tools are now primary leak sources, with internal repos being 6x more likely to expose secrets than public ones. A significant percentage of leaked secrets (64%) remain valid after years, highlighting gaps in rotation, revocation, and automated credential management. The shift to non-human identity governance and comprehensive visibility across systems are crucial to manage evolving secrets risks effectively. Secrets Sprawl Continues to Accelerate with Technological and Cultural Shifts Recent findings reveal that…

Fast Facts Honda has partnered with Macrium Software to enhance recovery readiness and minimize costly downtime across its U.S. manufacturing plants using centralized backup solutions. The collaboration involves deploying Macrium’s SiteBackup and Technician’s License to standardize protection and ensure rapid restoration of critical production systems. A recent report reveals manufacturers face a ‘recovery gap,’ with downtime costing upwards of $100,000 per hour, often caused by network errors and unvalidated backup systems, despite increased cybersecurity investments. Honda’s selection of Macrium aligns with industry trends, joining other automakers like Volvo and Husco in trusting Macrium’s solutions to protect mission-critical manufacturing operations. The…

Quick Takeaways A critical SQL injection flaw (CVE-2026-21643) in Fortinet’s FortiClient EMS version 7.4.4 is actively exploited worldwide, allowing unauthenticated remote code execution with a CVSS score of 9.1. Nearly 1,000 internet-facing servers are exposed, with threat actors bypassing security controls by injecting malicious SQL via HTTP headers, leading to data theft and lateral movement. Exploits include payloads targeting specific endpoints, such as /api/v1/init_consts, utilizing time-based SQL injection commands like ‘SELECT pg_sleep’, originating from known malicious IPs. Immediate mitigation requires updating vulnerable systems to version 7.4.5; security teams should monitor logs for suspicious HTTP requests and inventory exposed servers to…

Fast Facts Many critical ICS and OT devices remain exposed to the internet, making them vulnerable to nation-state cyberattacks, with attackers exploiting default credentials and known weaknesses. Case studies highlight targeted sabotage, such as the Russian-linked Dragonfly group compromising devices like Hitachi RTU560 and Moxa NPort, leading to operational disruptions and potential destruction. A significant portion (68.1%) of exposed devices are from Rockwell Automation, with others like Moxa, Siemens, and Schneider Electric also heavily targeted, revealing widespread vulnerabilities across global industrial markets. The U.S. accounts for nearly half of targeted devices, emphasizing ongoing threats from nation-states such as Russia, Ukraine,…
