Description

On December 14, 2015, ISIS-affiliated hackers operating under the name "Islamic Cyber Army" or "Cyber Caliphate" leaked personal information of 160 alleged military personnel from France and the United States. This action was a direct response to Anonymous' "ISIS Trolling Day" on December 11, during which the hacktivist group had defaced ISIS websites with mocking content, including replacing one site with a Viagra advertisement. The leaked data included full names, home addresses, phone numbers, and email addresses of mid-level military officials, specifically mentioning at least one French lieutenant general, several French colonels, and communications officers from the U.S. Strategic Command (STRATCOM). The information appeared on multiple ISIS-controlled social media accounts monitored by the SITE Intelligence Group. The hackers claimed possession of data for an additional 700 military personnel that remained unpublished. No official statements were issued by the U.S. Department of Defense or French Ministry of Defense regarding the breach.

This incident formed part of an ongoing cyber conflict between ISIS and Anonymous that intensified following the November 2015 Paris attacks. ISIS had previously leaked sensitive military data in March 2015 by publishing a "Hacked Hit List" of 100 U.S. military personnel with explicit calls for their assassination. In August 2015, the group's "Islamic State Hacking Division" released hundreds of records of U.S. government and military personnel obtained through compromised government servers. The December leak represented a continuation of ISIS' strategy to retaliate against cyber operations targeting their online presence while attempting to incite physical violence against military personnel. Anonymous concurrently expanded its campaign beyond ISIS during this period, targeting figures like Donald Trump over statements they believed aided ISIS recruitment.
