Advantage Media Services LLC (AMS), a fulfillment and media services company based in Valencia, California, has notified individuals that an unauthorized actor briefly accessed its server environment in September 2025 and copied certain data. This falls under hacking or system intrusion. AMS says it discovered suspicious activity, launched an investigation, isolated the affected systems, changed passwords, increased monitoring, and brought in outside data security and privacy professionals to help respond. The company also reported the incident to federal law enforcement and relevant government agencies.
The letter is addressed to people whose personal information was determined to be part of the data the unauthorized actor copied. AMS has not said how many people in total were notified, and the version of the letter reviewed here does not spell out the exact categories of information involved for this recipient, though it confirms that personal information was potentially impacted.
