US Tiger Securities Reports Data Security Incident to Washington AG

On May 15, 2026, US Tiger Securities Inc., which operates under the brand TradeUP Securities, Inc., officially reported a data security incident to the Washington Attorney General. As a financial institution providing brokerage services, US Tiger Securities handles sensitive personal information for its clients. The company confirmed that unauthorized parties gained access to its systems during this incident.

The public filing indicates that unauthorized access occurred, meaning data within US Tiger Securities' environment may have been compromised. While the specific types of personal information involved in this incident were not detailed in the official filing, individuals who received a direct notification from US Tiger Securities should be aware that their data was potentially exposed.

If you have received a data breach notification letter from US Tiger Securities, it confirms that your personal information was stored within the company's systems at the time of the incident. These letters are sent to inform you that your information may have been accessed by an unauthorized party, prompting the need for increased vigilance regarding your personal and financial security.

In response to such an incident, it is generally advisable to take proactive steps to protect your information. Regularly review all your financial account statements for any unusual or unauthorized activity. Be wary of unsolicited communications, such as emails, phone calls, or text messages, that request personal details, as these could be phishing attempts.

Considering placing a fraud alert on your credit reports with the three major credit bureaus (Equifax, Experian, and TransUnion) is also a recommended precaution. This can make it more difficult for identity thieves to open new accounts in your name. US Tiger Securities has indicated that the incident remains under investigation as they work to understand the full impact.
