The compromised information includes names, addresses, phone numbers, and email addresses. Valve confirmed that payment details and passwords remain secure. ## Valve alerts affected customers Valve spent the weekend compiling a list of at-risk customers and sent warning emails on Monday morning. The company stated that while CEVA is still investigating the attack, they wanted to inform all potentially affected customers based on current information. Customers were advised to be cautious of fraudulent messages attempting to verify orders. ## Warning against fake messages Valve warned customers about fake emails, SMS messages, and phone calls appearing to come from Steam, Valve, or shipping companies. These messages might reference hardware orders and even verify addresses to appear legitimate. They may ask for small customs fees or prompt users to 'verify' orders by logging in elsewhere. Valve emphasized all such communications are fraudulent. ## Steam support only communicates officially Valve reminded customers that Steam support only operates through the official help page and never contacts users via Steam chat or third-party services. Company employees will never ask for passwords or Steam Guard codes. Customers should be wary of any such requests and report suspicious activity immediately. ## Attack details remain unclear Many details about the attack remain unknown, including the number of affected customers, the extent of data stolen, and how attackers breached CEVA's systems. Valve stated it's pressuring CEVA for full disclosure of the breach's scope. Dutch authorities have also launched an investigation into the incident. ## Dutch authorities investigate The Dutch data protection authority confirmed receiving data breach reports from at least 10 companies related to this hack. Officials are investigating the cyberattack on CEVA Logistics' systems. This development comes amid increased scrutiny of data security breaches across Europe. ## Logistics operations impacted The cyberattack also disrupted operations at eight CEVA warehouses. According to FreightWaves, customers may experience delays or cancellations in upcoming orders. This could particularly affect customers waiting for hardware like Steam Machines. CEVA Logistics has not yet responded to requests for comment. ## Measures against data breaches This incident highlights how vulnerabilities in supply chains become targets for cybercriminals. Customers should protect their personal data by using multi-factor authentication and remaining vigilant against suspicious messages. Companies must rigorously audit their third-party partners' security measures to prevent similar breaches. ## Sources covering this story - https://www.cnet.com/tech/gaming/valve-warns-steam-machine-buyers-about-scam-messages-after-cyberattack/ — --- _Summary written by Brifing from the original reporting.
