May Trucking Company, a Brooks, Oregon-based interstate trucking and logistics carrier, recently disclosed a data security incident in which an unauthorized party accessed its network and acquired files containing personal information. Companies that collect and store Social Security numbers have a responsibility to implement reasonable safeguards to protect that information from unauthorized access.
May Trucking Company’s Data Breach Investigation
According to a notification letter filed with the California Attorney General, May Trucking Company detected suspicious activity within its network on June 21, 2026, and immediately began an investigation, engaging independent cybersecurity specialists to assist. That investigation determined that certain files had been acquired without authorization at the time the incident was detected. On July 23, 2026, the company learned that some of the affected individual’s personal information was contained within those files, and it then engaged a third-party vendor to issue notifications as quickly as possible.
Independent security researchers and dark-web monitoring outlets have separately reported that a ransomware group calling itself Embargo claimed responsibility for a June 2026 attack on May Trucking Company’s network, reportedly involving the theft of roughly a terabyte of data. May Trucking Company’s own notification letter does not name a specific threat actor or confirm a ransomware demand, describing the incident only as unauthorized access resulting in the acquisition of certain files; the corroborating reports nonetheless provide useful context on the scale and nature of the intrusion.
The trucking and logistics industry has increasingly become a target for ransomware and data-theft groups, in part because carriers maintain large repositories of employee and customer records, including Social Security numbers used for payroll, background checks, and driver qualification files, while often running on legacy IT systems that can be slower to patch than those at larger technology-focused companies. A breach exposing only names and Social Security numbers, as May Trucking Company has described here, is still considered high-risk: that specific combination is one of the most useful data pairings for identity thieves, since a Social Security number tied to a real name can be used to open new lines of credit, file fraudulent tax returns, or apply for government benefits in the victim’s name.
The roughly one-month gap between the company’s initial detection of suspicious activity (June 21, 2026) and its determination that specific individuals’ data had been affected (July 23, 2026) reflects the forensic review typically required to confirm which files were actually accessed and whose information they contained before a company can satisfy state notification-law requirements. May Trucking Company began sending notification letters to affected individuals on or around August 13, 2026, and has offered twelve months of complimentary identity protection services through IDX, including credit monitoring, dark web monitoring, and identity theft recovery services, to those affected.
When Did This Breach Occur?

Notification letters describing the breach began going out on or around August 13, 2026.
What Information Was Breached?
According to May Trucking Company’s notification letter, the information that may have been involved in this breach included affected individuals’ first and last names in combination with their Social Security numbers.
