Iran-linked hacker group Handala announced it had obtained and leaked thousands of images, documents, and videos belonging to former Israeli army chief of staff Herzl Halevi .
The group said on Thursday it was behind the operation, marking another instance of Israeli security officials being targeted in a "hack-and-leak" campaign.
In a statement, the group said it had obtained more than 19,000 “confidential images and videos”, including classified documents as well as personal photographs and files.
"For years, Handala has silently and relentlessly been right at the heart of General Herzi Halevi's system, the former Chief of Staff of the Zionist Army, watching, recording, and collecting everything that matters," the statement from the group said.
It added that it had accessed information related to "top-secret meetings" and "even crisis rooms of the Zionist military’s General Staff".
Some of the leaked material includes images from visits to military facilities, as well as official and unofficial meetings. Other images reportedly reveal the identities of Israeli pilots, commanders, and security operatives who had not previously been named or whose faces had been blurred.
The documents also include photographs of Halevi and his wife's passports, family trips, and images taken inside his home with relatives.
Another element of the leak reportedly includes details linked to internal databases of Israel’s largest health fund.
Israeli media said correspondence and contact lists from the phones of former Prime Minister Naftali Bennett, former Justice Minister Ayelet Shaked, and Prime Minister Benjamin Netanyahu's chief of staff, Tzachi Braverman, were also among the exposed data.
The leak further suggested that Halevi held meetings with counterparts in the region, including a reported undisclosed visit to Qatar and several secret flights on business jets.
The group did not specify how it obtained the material or which device was compromised. Israeli media reported that one possibility is that Halevi’s mobile phone or cloud accounts, such as Google or iCloud, were hacked.
Handala said it had “fully identified and archived” the documents.
The incident follows a similar operation in late March, when the group leaked personal correspondence and documents from the Gmail account of former Mossad director Tamir Pardo, exposing personal information, including his home address, travel history, and contacts.
Israeli intelligence services have warned about the group’s tactics, saying such operations are aimed at gathering personal data and building detailed intelligence profiles on targets.
The latest leak comes amid a wider backdrop of arrests and charges in Israel linked to alleged collaboration and espionage.
