A remote code execution (RCE) vulnerability in Burger King Spain’s backup system has reportedly been put up for sale by a cybercriminal operating under the alias #LongNight, stirring serious concerns about data security within the fast-food giant’s infrastructure. This development, widely discussed in cybersecurity circles, is being referred to as the “Burger King hack.”
The Burger King Hack/RCE Vulnerability
The Burger King hack/vulnerability is tied to AhsayCBS, a centralized backup server platform used for managing backups across local storage, FTP/SFTP servers, and cloud environments like AWS and Microsoft Azure. According to a report by KrakenLabs, #LongNight is offering RCE access to this system for $4,000, allowing potential buyers to execute arbitrary code during the beginning or end of backup processes—a dangerous entry point for further infiltration.

If the hacker’s claims are accurate, nearly 2.6 terabytes of sensitive data are at stake. This data could include customer information, financial records, and internal business documents, making it a prime target for ransomware deployment or illicit data sales. The hacking of Burger King’s backup infrastructure could therefore escalate into a large-scale breach with long-lasting repercussions.
Backup Systems as a New Frontline in Cyberattacks
Backup systems like AhsayCBS are typically considered an organization’s final protection against data loss. But when these systems are exploited, the attackers can gain persistent access and leverage the system’s core functionalities to hide malicious payloads or extract confidential information without detection.
The relatively low $4,000 price tag stresses how cybercriminals increasingly treat such vulnerabilities as tradable commodities, offering lucrative returns for minimal upfront investment. It reflects a troubling trend where threat actors can monetize even high-impact exploits with ease.
As of now, neither Burger King Spain nor Ahsay has issued public statements confirming the breach or detailing any mitigation efforts. The lack of official response leaves questions about the current status of the Burger King hack and whether appropriate countermeasures are underway.
