Cyber Incident Victim: Daniel's Hosting
Date:
Nov 2018
Location:
China
Summary
A major Dark Web hosting provider suffered a severe breach when attackers exploited a PHP zero-day vulnerability and potentially other flaws to gain administrative database access, resulting in the permanent deletion of all hosted data including over 6,500 sites. The operator confirmed no backups existed, making recovery impossible, and noted that while database rights were compromised, there was no evidence of full system access. The platform's open-source code availability may have facilitated vulnerability discovery. The operator disabled services pending identification of the exploited weaknesses, with attribution remaining unclear amid potential involvement of various threat actors.

Description
On November 15, 2018, between 10:00 and 11:00 PM UTC, attackers compromised Daniel’s Hosting, a major Dark Web hosting provider serving approximately 6,500 hidden services. The breach was confirmed by Daniel Winzen, the platform’s operator and developer, who discovered that hackers had accessed the hosting database with administrative privileges and systematically deleted all user accounts—including the "root" account—along with all associated service data. Attackers exploited a PHP zero-day vulnerability that had been publicly leaked one day prior to the incident. Although Winzen had patched this specific flaw in commit db626a54a4f5 before the attack, forensic analysis suggested additional unpatched vulnerabilities might have been leveraged to gain database access. The deletion of accounts and hosted content was irreversible due to Winzen’s deliberate design choice to operate without backups, leaving no recovery path for affected services. Initial log reviews indicated the attackers did not escalate privileges to full system-level access, as non-hosting-related accounts and files remained intact. Winzen disabled the platform immediately after detecting the breach and initiated a vulnerability assessment to identify the root cause.
The attack resulted in the permanent loss of all 6,500+ hosted Dark Web services, making it one of the most disruptive incidents against underground hosting infrastructure since Freedom Hosting II’s 2017 breach. Winzen publicly disclosed the compromise on the Daniel’s Hosting website, emphasizing that restoration would only be possible after identifying and patching the exploited vulnerabilities. He prioritized log analysis to determine the intrusion vector but reported incomplete findings at the time of disclosure. The platform’s open-source codebase, publicly available on GitHub, potentially facilitated attacker reconnaissance by exposing undiscovered flaws. While Winzen considered relaunching the service post-remediation, no timeline was provided. Attribution remained unclear, with possible actors including cybercriminal groups, state-sponsored hackers, or law enforcement agencies targeting Dark Web operations. The incident underscored systemic risks in niche hosting environments where operational security trade-offs—such as the absence of backups—amplified the impact of a single intrusion.
