Important Security Advisory - Increased Cyber Threat Activity
Phil Donoghue
March 1, 2026
Global events can have a direct impact on cyber security.
Following the recent escalation in tensions after joint US–Israel military strikes on Iran, cyber security analysts are warning of an increased risk of retaliatory cyber activity targeting Western organisations.
Reports indicate that cyber operations took place alongside the military action, and Iranian-aligned threat groups are already increasing reconnaissance activity and launching DDoS-style disruption campaigns. Security experts also warn that affiliated hacktivist groups may expand targeting efforts towards commercial and civilian organisations in allied countries - including UK businesses of all sizes.
Periods of geopolitical conflict often trigger a surge in opportunistic and coordinated cyberattacks. Businesses should be prepared.
What This Could Mean for UK Businesses
Organisations may see an increase in:
Phishing and spear phishing campaigns designed to harvest credentials
DDoS attacks intended to disrupt websites or online services
Ransomware or destructive malware activity
Previously leaked data being re-circulated and presented as new breaches
It’s also common during these periods for threat actors to exploit public fear, circulating themed phishing emails or impersonating trusted brands and government bodies.
Even businesses with no direct connection to global events can become targets.
Why Geopolitical Tension Increases Risk
Cyber operations are often used as part of broader strategic retaliation.
While government bodies and critical infrastructure are obvious targets, commercial organisations are frequently targeted because they are easier to disrupt and can create economic or reputational impact.
For SMEs in particular, opportunistic attacks may increase as attackers test defences and look for weak points.
Steps You Should Take Now
While there is no need for panic, there is a need for vigilance.
1. Increase Staff Awareness
Remind employees to treat unexpected emails, login prompts, and file downloads with caution - especially those referencing current global events.
2. Enforce Strong Account Security
Ensure multi-factor authentication (MFA) is enabled across all systems. Review and restrict administrative access wherever possible.
3. Apply Security Updates Promptly
Install all available patches for operating systems, servers, firewalls, and applications. Delayed updates remain one of the most common entry points for attackers.
4. Monitor for Unusual Activity
Keep an eye out for failed login attempts, unexpected password reset requests, or performance issues that could indicate malicious traffic.
