Cyber Incident Victim: Fur Affinity
Date:
May 2016
Location:
United States of America
Summary
A popular furry enthusiast community site experienced a multi-stage cyberattack initiated through exploitation of a known vulnerability in the ImageMagick library, enabling attackers to access and exfiltrate its source code. Following distribution of the stolen code via USB sticks at an unspecified convention, the perpetrators launched a secondary attack that deleted substantial user-generated content including art submissions and profiles, while also compromising email addresses and hashed, salted passwords. Site administrators mitigated further damage by restoring operations from a backup and resetting user credentials. The attackers were characterized as experienced despite researchers noting the exploit's trivial nature. While the restored backup limited permanent data loss, the incident underscored risks associated with reused credentials due to the potential decryption of stolen password hashes.

Description
In early May 2016, Fur Affinity—a prominent online community for furry enthusiasts hosting user-generated art, music, and writing—was compromised through an exploit targeting the ImageMagick library, a vulnerability publicly disclosed by researchers at the time. Attackers leveraged this flaw to execute arbitrary code on the site, gaining unauthorized access to Fur Affinity’s source code before administrators could apply security patches. Approximately one week after the initial breach, individuals at an unspecified convention distributed USB drives containing the stolen source code. On the same day as this distribution, attackers launched a second wave of intrusions using intelligence extracted from the source code, systematically deleting user-submitted content such as art and profiles. Administrators halted the attack before critical components like user journals and private notes could be erased, as confirmed by forum statements from Dragoneer, a site operator.
The breach resulted in the exposure of user email addresses and passwords stored in hashed and salted formats, though administrators emphasized this encryption reduced immediate cracking risks. Fur Affinity’s operations team, including Director of Operations "Chase," confirmed the theft of personal data in a May 13 forum post, while another administrator, "Fender," announced mandatory password resets by May 16. Site functionality was restored using a backup from May 11, minimizing permanent data loss. Administrators characterized the attackers as experienced based on the intrusion’s technical execution, contradicting external assessments that labeled the ImageMagick exploit as trivial to deploy. No attribution for the attack was established, and the incident underscored operational challenges in patching vulnerabilities promptly amid active exploitation.
