Viessman Trucking Data Breach Lawsuit Investigation
Did you receive a letter from Viessman Trucking about a data breach? Over 3,600 individuals may now face identity-theft risks after hackers accessed sensitive driver and Social Security data. Find out how to protect yourself and whether you qualify to file a claim.
What Happened?
According to filings with state regulators, Viessman Trucking—legally incorporated as Cliff Viessman, Inc.—detected suspicious activity within its network on or about August 5, 2025. A forensic investigation later confirmed that an unauthorized party not only accessed but also copied certain files containing personal information.
On September 10, 2025, the company mailed notification letters to affected consumers in multiple states, including New Hampshire and Vermont. The carrier is offering complimentary credit-monitoring services, yet victims may still incur out-of-pocket losses if their data is misused.
Information Exposed
The type and scope of data compromised varies by individual. Review your letter carefully. The breach may include:
- Name
- Social Security number
- Driver’s license number
- Protected health information (PHI)
With Social Security and driver’s license numbers in hand, criminals can open fraudulent accounts, file false tax returns, or conduct medical identity theft—often years after the breach occurs.
Your Legal Options
Companies that store personal data must use reasonable safeguards. If those measures fail, affected individuals may be entitled to:
- Reimbursement for out-of-pocket fraud or identity-theft costs
- Compensation for time spent addressing the breach
- Credit-monitoring and identity-protection services
- Statutory damages where allowed under state law
Class-action and individual lawsuits are already being evaluated. Acting quickly preserves evidence and your legal rights.
Next Steps to Protect Yourself
- Enroll in the free credit monitoring offered by Viessman Trucking.
- Place a fraud alert or credit freeze with each major credit bureau.
- Monitor financial and medical statements for unfamiliar activity.
- Consider identity-theft insurance if you need broader coverage.
- Document all expenses and time spent—these records strengthen potential claims.
