Top Cybersecurity News Stories From January 2026

As 2026 begins, cybersecurity news shows that the biggest risks no longer come from single attacks. They come from how fast threats spread through shared systems and critical infrastructure once attackers get inside.

This month’s stories span geopolitics, supply chain breaches, and day-to-day security operations. Together, they show how modern attacks blur the line between civilian and military systems, turn common platforms into force multipliers, and overwhelm teams with noise instead of clarity.

Across these stories, it’s clear that prevention alone isn’t enough. Visibility, observability, and containment are what determine whether an incident stays manageable or becomes a crisis.

This month’s news features insights from top security experts on:

• Critical infrastructure cyber risks from the U.S. Venezuela raid
• The Oracle breach as a ransomware force multiplier across shared software
• The growing need for observability in modern threat hunting
• The EU’s plan to tighten control over telecom supply chains

What the Venezuela raid reveals about cyber risk to infrastructure

In his Wall Street Journal article, Venezuela Raid Highlights Cyber Vulnerability of Critical Infrastructure, reporter James Rundle explored how modern conflict now reaches far beyond traditional battlefields and into everyday civilian systems.

Rundle examined the recent U.S. operation in Venezuela that coincided with widespread power outages in Caracas. While U.S. officials didn’t confirm a cyberattack, the timing raised new questions about how cyber activity may increasingly accompany physical military actions.

The incident highlights a growing reality that critical infrastructure such as power grids and water systems is no longer treated as off-limits during conflict. These systems often support both civilian life and military operations. This makes them shared or “dual-use” assets and more likely to be drawn into cyber conflict.

Illumio Public Sector CTO Gary Barlet explained why this creates serious risk. “You don’t normally see a jet fighter parked next to a school bus,” he said. “But in cyber, it does.”  

A single power system can serve a city and a military base at the same time, making it nearly impossible to isolate civilian impact once attackers gain access.

Rundle noted that global efforts to limit cyberattacks on civilian infrastructure remain weak, especially when nation-states are involved.  

Barlet reinforced that reality, warning that infrastructure operators can no longer assume neutrality. “All of us are in the battlespace, every person,” he said.  

In today’s threat environment, resilience and containment are essential to keeping critical services running when cyber conflict spills into daily life.

Oracle breach shows how shared software fuels ransomware risk

In his Wall Street Journal article, Oracle Hack Still Generating Ransom Demands, reporter Angus Loten examined how a breach in Oracle’s E-Business Suite software is still causing damage months after it was discovered.  

Oracle disclosed the incident in October 2025. But investigators believe attackers may have gained access as early as July. That gave them time to quietly steal data before launching ransom demands.

The impact continues to spread. More than 100 organizations may have been affected, including universities, airlines, manufacturers, and global companies. Victims reported receiving emails that threatened to leak stolen data unless they paid large ransoms.  

As Loten reported, this attack shows how a single flaw in widely used software can ripple across many industries at once.

Illumio Vice President of Information Security Erik Bloch explained why these types of attacks are becoming more common. “When thousands of companies rely on the same platform, a single compromise can cascade across industries,” he said.  

Attackers are no longer focused on breaking into one company at a time. They want scale, speed, and access to valuable data.

The breach also highlights a larger supply chain problem.  

Bloch warned that many attacks now start through trusted software providers, not direct intrusions. “The ecosystem is only as strong as its weakest link,” he said.  

This incident reinforces a hard truth for security teams. Prevention alone is not enough. Organizations need to be ready to contain damage when trusted software becomes the way in.

Why observability is the missing link in modern threat hunting

In his TechRadar Pro article, Threat hunters can’t waste time stumbling in the dark – they need real observability, Raghu Nandakumara, vice president of industry strategy at Illumio, argued that today’s most dangerous breaches don’t start with alarms. They start quietly.  

Attackers slip inside, move laterally, and spread while defenders remain buried in alerts. As Nandakumara put it, it’s not the initial intrusion that causes real damage but rather the time attackers spend undetected inside the environment.

He pointed to a hard truth many security teams already feel. The problem isn’t a lack of data but a lack of clarity.  

According to The 2025 Global Cloud Detection and Response Report, organizations now face more than 2,000 alerts a day, yet analysts spend over 14 hours a week chasing false positives.  

“More data does not necessarily equal better detection,” he said, noting that overlapping tools often create fragmented views instead of real understanding. Even with multiple cloud detection and response (CDR) platforms in place, 92% of organizations still report major gaps.

Attackers take full advantage of that confusion. Nandakumara explained that lateral movement remains the biggest blind spot in modern environments. Once inside, attackers move slowly and quietly, probing systems and escalating access.  

Nearly nine in ten organizations experienced an incident involving lateral movement last year, with breaches causing more than seven hours of downtime on average. And despite confidence in monitoring, almost 40% of east-west traffic still lacks the context needed to identify real threats.

That’s where observability changes the game.  

Nandakumara emphasized that defenders can’t hunt what they can’t see. Real observability means understanding how workloads, identities, and data flows connect and behave over time.  

“Observability must move beyond collecting more logs,” he said. Instead, teams need context that shows how systems relate, so they can spot an attack in motion, not after the damage is done.

He also addressed the role of AI. While AI and automation are essential for scaling security operations, they’re not magic fixes. “AI is most effective when it augments, not replaces, human expertise,” he said.  

When paired with security graphs and strong context, AI helps analysts connect the dots faster and focus on containment.  

For cyber leaders, success is no longer measured by how many threats you block, but by how quickly you detect, contain, and recover once an attacker inevitably gets in.

EU moves to phase out “high-risk” telecom suppliers from critical networks

In his The Register article, EU considers whether there’s Huawei of axing Chinese kit from networks within 3 years, reporter Dan Robinson detailed the European Commission’s plan to tighten control over telecom supply chains across the European Union (EU).

The Commission is proposing a revised Cybersecurity Act that would allow the EU to label certain vendors as “high-risk.” It would also require member states to remove their technology from critical networks.  

Under the proposal, countries could have as little as 36 months to phase out affected equipment. While no companies are named, the move is widely seen as targeting Chinese suppliers like Huawei, which still play a major role in Europe’s telecom infrastructure.

EU officials say the push reflects growing concern over hybrid attacks and supply chain risk. The Commission wants stronger, union-wide risk assessments and clearer rules for removing vulnerable components from networks.  

Former EU commissioner Thierry Breton previously warned that telecom gear from companies such as Huawei and ZTE could pose national security risks, especially in critical systems like 5G.

Huawei continues to deny that its products present any threat. A company spokesperson argued that excluding suppliers based on country of origin “violates the EU’s basic legal principles of fairness, non-discrimination, and proportionality.” They said Huawei would defend its interests as the legislative process unfolds.  

Even so, the proposal would prevent EU certification bodies from approving products from suppliers deemed high-risk.

Illumio Public Sector CTO Gary Barlet cautioned that security-driven decisions must be balanced carefully. “While efforts to achieve tech sovereignty and protect critical environments are understandable, an overly isolationist approach could create challenges,” he said.  

Barlet warned that fragmentation in the telecom ecosystem can limit collaboration and slow innovation. This would make it harder to build resilient networks over time.

The debate highlights a growing tension in cybersecurity policy. Governments want to reduce supply chain risk and protect critical infrastructure. But rapid “rip and replace” mandates can strain operators and disrupt services.  

As Europe moves forward, the real test will be whether it can strengthen resilience without weakening the networks it depends on.
