Surge in Hacktivist Attacks Signals Rising Cyberwarfare After Israel-Iran Tensions

The aftermath of the June 13 outbreak of open hostilities between Israel and Iran has not only played out on the battlefield but has rapidly escalated into a multifaceted conflict in cyberspace.

Following Israeli airstrikes on Iranian nuclear and military targets and retaliatory Iranian missile salvos, cyber operations have intensified, with both state-sponsored and non-state actors launching a barrage of disruptive cyberattacks, psychological operations, and sophisticated disinformation campaigns.

Israel, recognized globally for its advanced offensive cyber capability, struck first with monumental attacks on Iranian financial infrastructure.

Notably, the cyber unit known as Predatory Sparrow widely believed to be linked to Israeli intelligence claimed responsibility for crippling Iran’s state-owned Bank Sepah, rendering customer and business transactions inoperable and resulting in widespread data destruction.

This was swiftly followed by a breach at Nobitex, Iran’s premier cryptocurrency exchange, where attackers exfiltrated an estimated $81.7 million in assets, underscoring the vulnerability of digital financial ecosystems amidst geopolitical tensions.

Conversely, Iran’s cyber arsenal, traditionally comprised of state-backed APT groups such as APT34, APT35, and APT39, has pivoted toward leveraging disinformation and psychological influence as primary tactics.

Iranian actors have orchestrated waves of phishing, DDoS campaigns, and spoofed emergency notifications targeting Israeli civilians.

These operations aim to instill public panic and disrupt societal resilience without resorting to overt destructive attacks potentially conserving more potent cyber capabilities for future escalation.

Nonetheless, Israeli cyber authorities caution that Iranian hackers may yet deploy ransomware or wiper attacks against critical services if the conflict’s trajectory intensifies.

Global Cyber Fallout

Parallel to official digital hostilities, independent hacktivist groups have surged, transforming the Israel-Iran war into a rallying cry for ideological cyber militancy.

Over 100 groups predominantly pro-Iranian and rooted across the Middle East and Asia have actively claimed credit for cyber disruptions, including website defacements, service outages, and data leaks.

Israeli sectors most frequently targeted include government, manufacturing, telecommunications, media, and banking, with DDoS attacks peaking during the initial days of kinetic conflict.

Leading the charge are collectives such as Mr Hamza and Arabian Ghosts, orchestrating campaign-style attacks not only against Israeli assets but also extending their operations to the United States and the United Kingdom.

This broader targeting reflects escalating concerns over potential spillover, where cyber crossfire may impact global infrastructure and organizations far removed from the immediate conflict zone.

Battle for Digital Narrative

As technical attacks intensify, information warfare has emerged as a decisive front. Iranian state and affiliated actors have deployed coordinated online campaigns to disseminate fake alerts, manipulate social media with bot networks, and propagate misleading or AI-generated imagery.

According to the Report, Analysts have documented the spread of deepfakes and fabricated battlefield content, which are circulated with the explicit aim of amplifying outrage, confusion, and division.

The Iranian regime has further clamped down on domestic internet access and foreign media, seeking to contain Israeli psychological operations and control national sentiment.

Within Israel, cybersecurity experts and authorities are on high alert, anticipating that the current wave of hacktivist activity and disinformation will precede more severe cyber intrusions.

Both nations are acutely aware that digital escalation remains a potent tool for asymmetric warfare and domestic influence.

The first week of hostilities in the Israel-Iran conflict has confirmed cyberspace as an indispensable battleground of modern warfare.

With state-sponsored attacks, hacktivist campaigns, and aggressive disinformation efforts converging across digital domains, the threat of regional and potentially global cyber spillover has never been more acute.

As critical infrastructure defenses are tested and narratives manipulated in real time, the conflict serves as a stark reminder: in contemporary conflicts, control of information and infrastructure is as consequential as control of territory.
