The geopolitical landscape shifted sharply after the coordinated strikes on Iran on 28 February 2026, marking the beginning of a hybrid conflict that fuses kinetic operations with sophisticated cyber retaliation. For CISOs and executive leaders responsible for safeguarding U.S. critical infrastructure, the evolving threat environment requires heightened vigilance and proactive defensive strategy. Cyber operations have emerged as a primary tool of state retaliation, and Iran’s response has demonstrated a willingness...

Crime-as-a-Service has evolved from underground forums trading scripts into a mature ecosystem that mirrors legitimate SaaS and gig platforms. In 2026 attackers do not need deep technical skills to execute complex campaigns. They can rent initial access, subscribe to ransomware toolkits, outsource phishing operations, buy infostealer logs, and spin up botnets on demand. Packages come with dashboards, SLAs, technical support, onboarding guides, and even affiliate revenue splits. The barrier to...

Enterprises have embraced software as a service for agility, cost efficiency, and collaboration at scale. Email, chat, document management, CRM, HRIS, ERP, developer platforms, analytics suites, and identity providers all live in the cloud and update continuously. This shift has created an unintended advantage for adversaries. Attackers no longer need to drop obvious malware or probe perimeter defenses to achieve their goals. They can live off the SaaS by abusing...

Passwordless authentication is a breakthrough for phishing resistance and user experience. Passkeys, FIDO2 security keys, Windows Hello, platform authenticators, and WebAuthn flows eliminate shared secrets and dramatically reduce credential phishing. Yet removing passwords does not remove insider risk. It changes where the risk hides. In a passwordless world the path to compromise shifts from guessing or stealing a password to exploiting recovery paths, session artifacts, device trust, identity governance, and...

Quantum computing is no longer a distant research project. While practical, large scale quantum computers are still emerging, security leaders must plan for a world where today’s public key cryptography can be broken. The most urgent risk is the harvest now decrypt later model where attackers intercept and store encrypted data today with the expectation that quantum capabilities will decrypt it in the future. If your organization holds long lived...

Traditionally, security strategy revolved around protecting a clearly defined perimeter. Firewalls, intrusion prevention systems, network segmentation, and VPNs were designed to keep attackers out and users in. That model assumed that once an attacker breached the perimeter, the damage would be contained or at least detectable. That assumption no longer holds. The perimeter did not disappear. It moved Modern enterprises operate across cloud platforms, SaaS applications, remote workforces, APIs, and...

For years, many organizations framed ransomware as a problem of big names. A few dominant groups, a handful of infamous leak sites, and a predictable cycle of encrypt, extort, and move on. That mental model is now outdated. Ransomware has entered the fragmentation era, where smaller gangs, affiliate splinters, and short-lived brands create a threat environment that is more volatile, more opportunistic, and in many ways more dangerous than the...

The new reality: attacks that plan, adapt, and execute on their own Security teams have spent decades building detection programs around a familiar assumption: attackers act in steps that are predictable enough to model. A phishing email lands, malware executes, persistence is established, lateral movement begins, and then the attacker monetizes. Even when adversaries became stealthier, most defensive tooling still relied on the idea that malicious behavior would show up...

The recent Notepad++ incident is not a traditional software vulnerability in the editor itself. It is a supply chain style compromise where attackers interfered with how update traffic was delivered and verified, selectively redirecting a subset of users to attacker-controlled infrastructure that served malicious update artifacts. The Notepad++ maintainer describes an infrastructure-level compromise at the hosting provider that enabled interception and redirection of update traffic destined for notepad-plus-plus[.]org, with targeting...

Threat actors are increasingly abusing the implicit trust users and organizations place in legitimate, digitally signed software. Instead of delivering obviously malicious binaries, attackers now rely on well known applications such as PDF tools, remote access software, and IT administration utilities as the initial lure. Social engineering convinces victims to install or execute these programs, after which attackers exploit weaknesses in how the software loads dependencies, handles updates, or accepts...
