Critical OT access points-engineering workstations (EWS) and human-machine interfaces (HMIs)-are prime targets for threat actors looking for a network foothold to expand deeper into process control systems, or the enterprise network. Yet Claroty Team82 recently discovered 13.2% of those assets were insecurely connected to the internet. Download the research report to learn how locking down remote and third-party access across OT networks significantly reduces the attack surface available to advanced threat actors.   https://oal.lu/yksbP   #OTsecurity #Team82 #cybersecurity

A recent wave of massive network scans has targeted Cisco ASA firewalls and IOS devices, revealing over 25,000 unique IP addresses engaged in probing activities. Notably, around 80% of these origins trace back to a Brazilian botnet, illustrating how automated threat actors leverage global resources to map vulnerable systems. This two-phased scanning campaign focused on login portals, Telnet, and SSH, classic reconnaissance tactics hinting at preparatory work for potential exploits. Historically, such intense scanning precedes exploit attempts or disclosure of new vulnerabilities. The , often coordinated, nature of these campaigns suggests an industry-wide trend: threat actors continuously refine their approach, seeking out weaknesses before launching larger attacks. Past incidents show nearly 80% of similar campaigns have led to CVEs or zero-day exploits, underscoring the importance of proactive security measures. For defenders, this signals a critical reminder: visibility and readiness are paramount. Ensuring all patches are applied, especially to known Cisco vulnerabilities, and enforcing MFA on all remote management interfaces can thwart many attack strategies. Reducing exposure by blocking unnecessary external access, using VPNs, reverse proxies, or access gateways, transforms the network perimeter from a fragile barrier into a stronghold. Staying alert to threat intelligence feeds from sources like GreyNoise can provide early indicators of malicious scanning activity. Looking ahead, as automation and AI-driven botnets grow more sophisticated, the volume and speed of reconnaissance will only increase. Recognizing early warning signs and responding swiftly are essential to prevent potential breaches. These widespread scans aren't just routine noise, they're a vital call to action. Organizations that bolster their defenses, maintain vigilance, and adapt to evolving tactics will be better positioned to weather future storms.

Physical security systems such as access control, video surveillance, and intrusion detection were once stand-alone tools. Today, they are networked, integrated, and dependent on an internet protocol (IP) infrastructure.  This shift brings powerful capabilities but also significant risks. These systems are now targets for cyber threats. Nearly 30% of organizations report cyber incidents tied to physical security systems, often due to outdated firmware, weak passwords, or poor network segmentation. A compromised camera or badge reader can quickly become an entry point for attackers. At Safeguards Consulting, we believe cyber-hardening is essential. Our consulting approach strengthens resilience at every layer by focusing on secure configuration and encryption, proactive patch and firmware management, network segmentation with monitoring, and comprehensive incident response planning.   When organizations align physical and cyber protections, they gain the confidence that their people, assets, and spaces are secure against evolving threats. The question is no longer if you need to cyber-harden your physical security and other Operational Technology (OT) systems, but how soon you can make it a priority.   To learn how our team of trusted advisors can help, visit:  https://lnkd.in/e457TjNq   #PhysicalSecurity #CyberHardening #SecurityStrategy #RiskManagement #SafeguardsConsulting
