Cyber warfare against Israel is intensifying, with reported incidents jumping by 24% in 2024. According to the Israel National Cyber Directorate (INCD), this surge is largely driven by Iran and its affiliated militias. While the sheer volume of attacks has increased dramatically, the nature of the conflict is also changing. Attackers are moving away from simple disruption and toward more sophisticated, long-term infiltration tactics, signaling a new and more dangerous phase in the digital conflict.
A Shift from Public Chaos to Targeted Strikes
The conflict’s evolution is stark when looking at the numbers. The INCD recorded 736 alerts in 2024, a significant leap from 367 the previous year. Calls to Israel’s cyberattack hotline also swelled to 17,078. In the initial phase following the October 7, 2023 attacks, the goal was widespread panic and disruption.
These early attacks were chaotic and aimed at civilian life. Attackers focused on public-facing systems to cause maximum confusion. Some of the most disruptive incidents included:
- Hacked public address systems that blared frightening warning messages in kindergartens.
- A massive denial-of-service attack that crippled point-of-sale systems at gas stations and supermarkets nationwide.
- Hijacked digital billboards used to display violent and threatening messages to the public.
As Israeli defenses hardened against these brute force methods, attackers shifted their focus. Phishing attempts on businesses, particularly managed service providers (MSPs), became the most common intrusion method, accounting for 41% of all hotline reports this year.
Iranian Cyber Units Accelerate Their Tactics
One of the most concerning developments is the speed at which Iranian-backed groups now operate. According to Tom Alexandrovich, an executive at INCD’s defense division, the time it takes for these groups to exploit a newly discovered software vulnerability has been drastically reduced. “What used to take them days or even a week, now happens in just 40 minutes,” Alexandrovich warned.
This rapid acceleration is the result of a strategic shift. Instead of developing their own tools from scratch, Iran-aligned hacker groups are now purchasing access from other cybercriminals and weaponizing vulnerabilities almost immediately. They have also improved coordination, sharing intelligence and attack tools among different units to reduce preparation time.
Furthermore, their goals have changed from short-term attacks to long-term infiltration. By embedding themselves deep within supply chains and using legitimate software already on a system, they make malicious activity nearly impossible to spot. This covert approach allows them to maintain access for future operations.
Israel’s Military Ecosystem in the Crosshairs
While civilian infrastructure is still a target, Iran’s hackers are increasingly aiming at Israel’s national security apparatus. “A good target for cyber operations is anything that supports the Israel Defense Forces (IDF),” Alexandrovich noted. This broadens the list of potential targets to include transportation networks, emergency services, food manufacturers, and even missile defense suppliers.
To defend against these threats, Israel has launched the “Cyber Dome” project. Modeled after the Iron Dome missile shield, this AI-powered initiative provides enhanced protection and monitoring for critical entities. Israeli cybersecurity teams have identified and mapped out 3,000 companies that are essential to the IDF’s logistics and operations, placing them under this digital umbrella.

Beyond the Code: The Psychological War of Attrition
The cyber conflict extends beyond technical breaches; it is also a psychological battle. The relentless stream of alerts and threats is designed to wear down organizations and their security teams. “Imagine being told every day that your systems are under attack,” Alexandrovich said. “How long before you stop reacting? Before exhaustion sets in? That’s the goal—constant, grinding pressure.”
This strategy of inducing fatigue mirrors the broader physical conflict. In a recent example, Houthi militants fired a ballistic missile toward central Israel. Although sirens sounded, many citizens barely reacted. The missile was intercepted, and no one was harmed, but the event highlighted a growing desensitization to constant threats.
In cyber warfare, the damage is not always as visible as a missile interception. The threat is persistent, and the lines are blurry. While Israel’s digital defenses are holding for now, the conflict is clearly entering a new, more challenging phase.
Frequently Asked Questions
What is the main change in cyberattacks against Israel in 2024?
The main change is a shift from high-volume, disruptive attacks designed to cause chaos to more sophisticated, targeted attacks. Iranian-backed hackers are now focusing on long-term infiltration and exploiting software vulnerabilities with unprecedented speed.
Who is behind the increase in cyberattacks on Israel?
The Israel National Cyber Directorate (INCD) attributes the significant increase in cyber incidents primarily to Iran and its affiliated militias and hacker groups.
How is Israel defending its critical infrastructure?
Israel is using a multi-layered defense strategy, including the “Cyber Dome” project. This AI-powered initiative provides extra protection and monitoring for 3,000 companies that are vital to the logistics and operations of the Israel Defense Forces (IDF).
What is the “psychological toll” of this cyber warfare?
The constant and relentless nature of the cyberattacks is intended to cause “alert fatigue.” This wears down security personnel and organizations, potentially leading to slower reaction times and exhaustion, which is a strategic goal for the attackers.
How quickly are Iranian hackers exploiting new vulnerabilities?
According to the INCD, Iranian hackers can now exploit a newly discovered software vulnerability in as little as 40 minutes, a process that used to take them days or weeks. This is due to better coordination and purchasing access from other cybercriminals.
