Artificial intelligence is gradually being integrated into operational technology environments, ranging from predictive maintenance to decision-support systems powered by machine learning and large language models. For critical infrastructure operators, this presents a dual challenge: harnessing AI for efficiency while maintaining safety, availability, and cybersecurity .   In December 2025, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) , together with cybe

Email remains one of the most underestimated cyber risks in operational technology environments . It is often treated as an IT-layer concern, something isolated from industrial processes and unrelated to the functioning of physical equipment. In reality, OT network security teams depend on a continuous flow of operational messages, automated alerts, vendor communications, firmware packages, and field reports that enter the environment through enterprise communication channel

Crypto asset service providers rely on the ability to transfer digital assets efficiently between hot environments and cold storage environments. As threat actors increasingly target exchanges and custodians, the design of transfer workflows has become one of the most crucial aspects of crypto asset storage security .   Hot systems are crucial for client withdrawals, liquidity management, and exchange operations. Cold systems safeguard long-term reserves, private keys, and h

Critical infrastructure operators now rely more than ever on accurate operational technology data. Logs, historian outputs, configuration reports, maintenance files, and compliance evidence all need to be transferred from OT systems to IT environments where analytics, monitoring, and decision-making take place.   While essential for operational continuity and regulatory compliance, this flow of information also introduces one of the most underestimated risks inside industrial

In crypto asset custody , most institutions know how to secure assets at rest. They invest in robust storage environments, use air-gapped cold wallets , and apply multi-layered controls around private keys. However, as experience shows, the greatest cyber risks often occur not when crypto assets are storage, but when they move.   Every transfer of crypto assets, whether it’s between a cold wallet and a hot wallet or across a crypto asset service provider’s internal network, c

In the world of digital finance, trust is everything. Yet, in crypto asset custody , trust is not built solely on perception or reputation; it is built on verifiable security . Every cold wallet, every crypto asset storage facility, and every transaction channel represents a potential breach point in a system that must, by design, remain uncompromised. To achieve that, crypto asset service providers must architect their custody systems around a single, non-negotiable principl

Email is still the most frequently exploited vector in cyberattacks targeting enterprises. In 2024 alone, the FBI’s Internet Crime Complaint Center (IC3) reported over $2.8 billion in losses  from Business Email Compromise (BEC), affecting more than 21,000 organizations worldwide. Meanwhile, phishing volumes continue to rise, with the Anti-Phishing Working Group recording more than 1.1 million phishing attacks  in Q2 2025, a new high for the decade.   The consequences of th

Energy and utility operators collaborate constantly with external vendors, contractors, and remote field teams. These partnerships often involve transferring files into protected OT networks , including software updates, diagnostic logs, engineering reports, and configuration changes.   But while the files themselves may seem harmless, the way they enter the network is where the risk lies. USB drives passed between field teams, portable laptops brought in by vendors, or remo

In industrial environments, the boundary between SCADA systems and corporate IT networks is often assumed to be secure. Yet in many architectures, these two domains are more connected than most realize. Whether through shared infrastructure, reporting interfaces, or vendor access, attackers increasingly exploit these connections to move laterally between operational and enterprise zones .   When a threat actor gains a foothold in one environment, the next objective is almost

For decades, operators in the energy sector have leaned on the belief that their OT environments are “ air-gapped ”, which means they are...

Industrial organizations face an ongoing paradox: networks must remain connected enough to support productivity yet isolated enough to...

Phishing remains the most pervasive cyber threat facing organizations today. As of 2025, phishing is responsible for 31% of all data...

We conducted a jurisdiction-by-jurisdiction review of the legal texts (and, in the U.S., formal statements) to determine their specific provisions regarding cold-wallet security and adjacent controls.

Artificial intelligence in cybersecurity is not inherently good or bad. Its effectiveness depends entirely on how it’s implemented and how well organizations prepare for the ways it can be misused.

The Erlang/OTP SSH flaw didn’t just expose a coding error; it exposed a systemic truth: remote access is only as secure as the software behind it.

This attack by Dropping Elephant represents a geopolitically motivated, sophisticated cyber-espionage campaign directly targeting Turkey's ascent in defense technologies.

The Procolored malware incident highlighted how easily malicious software can travel undetected, particularly through the USB workflows that many OT environments still rely on.

A chronological breakdown of how OT-targeting malware has evolved and how threat intelligence and diode-based defense are rising in response.
