In a rapidly escalating cyber conflict, the United States and Israel launched a major joint cyber offensive, dubbed Operation Epic Fury (U.S.) and Operation Roaring Lion (Israel), on February 28, 2026.
In retaliation, Iran’s cyber capabilities have been severely affected due to widespread internet disruptions. However Paloalto Networks, hacktivist groups aligned with Iran have filled the gap, intensifying their cyber activities.
This article explores the impact of the conflict on cybersecurity, highlighting the response from Iran-backed groups and the global implications.
On February 28, 2026, Iranian internet connectivity dropped drastically, falling to between 1-4% of its usual capacity.
This loss of connectivity disrupted Iran’s state-aligned cyber units, limiting their ability to execute large-scale cyberattacks.
The degradation of communication channels within Iran’s leadership and command structures likely impacted the coordination of sophisticated, state-sponsored operations in the near term.
While Iran’s primary cyber actors may have been hindered, the attack’s scale and complexity shifted the focus to hacktivist groups operating outside Iran.
These groups, some claiming affiliation with Iran, began targeting adversarial nations, including Israel and the U.S.
Hacktivist groups, often more dispersed and less reliant on centralized coordination, launched a series of disruptive cyberattacks against various government and civilian sectors.

The attacks have been marked by low to medium sophistication, including Distributed Denial-of-Service (DDoS) attacks, website defacement, and data exfiltration campaigns.
Hacktivist Surge and Cybersecurity Threats
Despite the scale of these attacks, they have yet to cause a catastrophic breach. The attacks have targeted various sectors, but they are primarily focused on creating disruption rather than executing complex espionage or sabotage.
As the situation continues to evolve, analysts believe that Iran’s state-backed actors may struggle to launch more sophisticated cyberattacks in the short term due to internal operational disruptions.
However, the persistence of hacktivist groups, fueled by political motivations, will keep cyber threats alive. These groups are expected to continue targeting governments, organizations, and infrastructures they perceive as adversaries.
According to Paloalto Networks research, in the face of these escalating attacks, experts recommend that organizations bolster their cybersecurity defenses with a multi-layered approach.
Governments and critical infrastructure operators need to enhance monitoring for suspicious activity, especially in internet-facing systems.
Employees must also be educated about phishing and social engineering tactics to mitigate the risk of data breaches and malicious exploitation.
The ongoing cyber conflict between Iran, the U.S., and Israel has led to significant disruptions in the region’s cyber activities.
While Iran-backed state actors are currently limited in their ability to launch advanced attacks, hacktivist groups continue to escalate their efforts, focusing on disrupting Israeli and U.S. interests.
As the conflict unfolds, the global cybersecurity community remains on alert, with threats expected to persist in the coming weeks.
