Hamas leaked detailed dossiers of more than 2,000 Israel Air Force (IAF) personnel, “Israeli” newspaper Haaretz reported on Monday. 

The extensive files, created as part of Hamas' intelligence-gathering operations, contain sensitive personal information about key figures in the IAF, including chief technicians, aerial defense specialists, and pilots.

The dossiers, labeled with the purpose "As revenge for the killers of [the] children of Gaza," include the soldiers' full names, unit affiliations, ID numbers, contact details, social media accounts, family names, and in some cases, passwords, license plates, credit card numbers, and bank account information. 

These reports, varying in length from a few pages to over 200 pages, have been circulating online for months and were recently shared with an international team of investigative reporters led by Paper Trail Media in collaboration with Germany's Die Zeit and ZDF, Austria's Der Standard, and Haaretz.

The information in the reports appears to have been obtained from a combination of leaked data, hacks into non-Israeli Occupation Forces (IOF) websites, social media scraping, and public databases. 

An automatic tool known as a profiler was used to compile and cross-reference this information, creating detailed profiles on the targeted individuals. 

Experts in cybersecurity and national security warn that these leaks represent a severe threat. The data could potentially be used for a range of malicious activities, including revenge attacks, doxxing, surveillance, and legal threats against the individuals involved. 

Col. (res.) Dr. Gabi Siboni, a cyber warfare expert, emphasized the danger of such information falling into the hands of hostile entities like Hamas, Iran, and Hezbollah.

Efforts to mitigate the impact of these leaks have been ongoing, with “Israeli” authorities working to remove the data from online platforms and block access to accounts distributing the information. 

Despite these measures, the continued availability of this data online poses a persistent threat to the individuals involved and to “Israel's” national security.

Ben Am, co-founder of Telemetry Data Labs, noted that the operation appears to be a sophisticated "hack and leak" orchestrated by Iran, with the data being distributed by various hacker groups and amplified through social media and other online platforms.

“Israeli” authorities responded by advising citizens to minimize their online exposure, secure their social media profiles, and use unique passwords for their devices. 

The IOF also stated that it is actively combating Hamas' intelligence-gathering efforts and working to protect its personnel from such threats.
