Landstar System Holdings Data Breach Exposes Sensitive Personal Information
On April 30, 2026, Landstar System Holdings, Inc., a major provider of transportation and freight services, detected unauthorized activity within one of its business applications. The company swiftly blocked the access and launched an investigation with external cybersecurity experts, confirming that an unauthorized actor had accessed certain systems and storage locations between April 29 and April 30, 2026.
By May 22, 2026, Landstar determined that exposed files contained sensitive personally identifiable information (PII), including names, Social Security numbers, driver’s license numbers, and government ID numbers. The breach affected individuals across multiple states, with 726 in Texas, 23 in Maine, 7 in Massachusetts, and 3 in Vermont identified as impacted.
Landstar began notifying affected individuals via U.S. mail on June 11, 2026. The incident is now under investigation by Shamis & Gentile P.A., a law firm specializing in data breach class actions, which is evaluating potential compensation claims for those affected.
