Grubhub Cyber Attack Highlights Growing Threat of Data Breaches and Credential Theft

Grubhub, a food delivery website, has disclosed a recent data breach, raising new concerns about cybersecurity threats in technology companies. According to the corporation, hackers obtained illegal access to several of its internal systems and downloaded a limited amount of data. However, Grubhub stated that sensitive information such as credit card numbers, bank account information, and food order history were not compromised.

The company shared that it is taking the incident seriously and has already started working with a third-party cybersecurity firm to investigate the breach. Law enforcement agencies have also been informed. According to sources, the hack was carried out by the well-known cybercrime gang ShinyHunters. The organization is apparently demanding a Bitcoin ransom and threatening to reveal stolen data unless the payment is paid. This data allegedly includes older customer information from a Salesforce breach in February 2025, as well as newer customer assistance data from Grubhub's Zendesk system.

Grubhub uses Zendesk to manage customer service chats, while Salesforce is used for managing business and customer data. Investigators believe the breach happened due to stolen login credentials linked to earlier Salesloft Drift data theft attacks. In those attacks, hackers misused compromised tokens connected to Salesforce integrations. These stolen tokens helped attackers access more systems and collect login details for future attacks.

This incident underscores a rising cybersecurity vulnerability known as follow-on attacks, in which hackers utilize previously stolen data to gain access to new systems. ShinyHunters has a history of such attacks, and has previously claimed to have stolen approximately 1.5 billion data records from Salesforce-linked platforms. Cybersecurity experts warn that organizations harmed by such intrusions should respond fast. This involves rotating access tokens, altering confidential information, and tightening security controls to prevent additional damage. The Grubhub breach is an important reminder that data protection, cloud security, and frequent system monitoring are essential in today's digital environment.

As cyber threats continue to rise, businesses and users alike must stay alert and prioritize strong cybersecurity practices to protect personal and company data. Regular security audits, timely software updates, and strong access controls can help reduce the risk of future attacks. Staying informed about the latest cyber threats is now essential for long-term digital safety and trust.
