The Handala hacking group has announced a cyber operation targeting an Israeli military unit responsible for monitoring and analyzing media intelligence, publishing more than 500 classified documents and tens of thousands of internal messages.

Handala announced on Sunday that it had infiltrated the Israeli military’s Media Intelligence Monitoring and Analysis Unit and released its internal documents and correspondence.

According to the group, “the operation has exposed new vulnerabilities in Israel’s intelligence and media systems.”

The unit monitors and analyzes media outlets and is connected to Israeli military intelligence structures, including Unit 8200 and the military censorship department.

Handala directed users to the websites “DataSecret” and “DropSite” to access the documents and internal messages released in the operation.

The group described the operation as “a blow to Israel’s information security infrastructure” and warned that further cyber operations targeting Israel’s media and cognitive warfare activities would follow in the near future.

Handala also said it would disclose further details about the unit’s organizational structure and the extent of its access to Israeli military intelligence systems in the coming period.

Handala says hacked account of Israeli opposition leader, reveals secret ties to Netanyahu

The Handala hacking group says Tzipi Livni has behind-the-scenes ties and cooperation with Benjamin Netanyahu, calling her public opposition a "scripted performance."

The latest operation follows Handala’s September disclosure of selfie images belonging to around 700 Israeli so-called security personnel.

The images were released after the group gained access to the phones of hundreds of people linked to Israel’s so-called security structures, exposing personal material captured by their devices.

“The operation demonstrates our ability to penetrate systems used by Israeli security personnel and obtain sensitive information,” Handala remarked.

The group said it had used a cyber tool called “Na’em” in the operation and described the release of the images as a warning to Israel’s so-called security establishment.

Handala also referred to a joint warning by the US, Britain, and the Netherlands concerning the tool, calling it a challenge to Israeli and Western cybersecurity systems.

The group has continued to publicize cyber operations targeting Israeli intelligence structures, challenging Israel’s claims of technological and cybersecurity strength.
