On October 7th, 2023, at 6:30 a.m., Hamas launched rockets into Israel, breaking through the Gaza barrier to attack major cities. The physical impact was immediate and devastating. However, the digital landscape was also a battlefield, one that holds particular significance for U.S. defense and technology companies tied into global supply chains.

Hours before the rockets hit, the Jerusalem Post reported experiencing a cyber-attack. Soon after, Israel’s energy grid and critical infrastructure were also targeted. These digital strikes had ripple effects, compromising companies responsible for the security and monitoring of not only Israeli assets but global ones.

The Digital Battlefield: A Timeline

The Israel-Hamas conflict has been a crucible for escalating cyber activities, pulling in various state-sponsored actors and hacktivist groups. Here’s an expanded timeline of cyber events:

October 7th, 2023: Initial Attacks

  • 6:30 a.m.: Hamas launches rockets at Israel.
  • Less than 1 hour after the initial attack: Anonymous Sudan targets Israel’s emergency warning systems and claims to have disrupted alerting applications.
  • Same Day: Jerusalem Post targeted by Anonymous Sudan.

Intensification and Escalation

  • Pro-Hamas group Cyber Av3ngers: Targets Israel Independent System Operator (Noga), shutting down its website and compromising its network. Also targets Israel Electric Corporation and a power plant.

  • Ghosts of Palestine: Calls for global hacker participation to attack infrastructure in Israel and the U.S.
  • Libyan Ghosts: Begins defacing small Israeli websites in support of Hamas.

Types of Attacks

  • Majority of the attacks are Distributed Denial-of-Service (DDoS), aimed to disrupt and disable services. Some groups, like Killnet and Anonymous Sudan, have previously engaged in highly disruptive attacks against major companies like Microsoft and Telegram.

For Business Executives: Tips to Remain Vigilant

  • Conduct a Rapid Third-Party Risk Assessment
  • Monitor Systems for Suspicious Activities
  • Change Passwords for Email and Other Critical Systems
