The company confirmed that information such as Full Name, Social Security Number, Date of Birth, Wage and Compensation Information, Tax Return Information, Direct Deposit Account Details, Mailing Address, and Telephone Number may have been exposed. The combination of these data types creates significant risks for affected individuals.

Exposed data like Social Security Number and Date of Birth are foundational elements used by cybercriminals for identity theft, which can lead to fraudulent accounts or tax refund fraud. Furthermore, the compromise of Direct Deposit Account Details and Wage and Compensation Information could make individuals vulnerable to direct financial account takeover attempts and targeted phishing scams.

Companies that handle such sensitive employment data, including staffing firms like Cornerstone Staffing Solutions, have a legal responsibility to implement robust cybersecurity measures. A data breach of this nature often prompts questions about the adequacy of security protocols, especially under state and federal data protection standards that aim to safeguard consumer information.

It is important to carefully review your letter to understand the specific data categories that pertain to you.

What to do if you were affected

Based on the categories of information reported in this filing, these steps can help limit the risk of identity theft and fraud.

  • Freeze your credit

    Place a free credit freeze with Equifax, Experian, and TransUnion. A freeze blocks new accounts from being opened in your name and can be lifted anytime.

  • Guard against tax fraud

    File your tax return as early as possible and consider requesting an IRS Identity Protection PIN so no one can file a fraudulent return in your name.

  • Watch your financial accounts

    Review bank and card statements for unfamiliar activity and turn on transaction alerts. Report anything you don't recognize to your bank right away.

  • Stay alert to targeted scams

    Be cautious of calls, texts, or emails that reference this breach. Legitimate organizations won't ask you to confirm sensitive details through an unsolicited message.

  • Keep your notification letter

    Save the notice you received. It documents that your information was involved and is often needed to enroll in any credit monitoring offered or to join a related legal claim.
