Levin, Sedran & Berman, LLP, a law firm based in Philadelphia, has notified individuals of a data security incident and filed a sample notice letter with the California Attorney General. This page explains what the notice says, what it leaves out and what affected people can do now.
The details below come from the firm’s own sample notice and a state listing, and they may change if more information is released.
Levin, Sedran & Berman, LLP’s Data Breach Investigation
Levin, Sedran & Berman, LLP is a law firm with offices at Walnut Street in Philadelphia, Pennsylvania. Like any firm, it holds files on clients, adversaries, witnesses, employees and others, and those files can include names, financial details, identification numbers and other sensitive personal information gathered during legal work.
According to the firm’s sample notice letter, it identified potentially suspicious activity on its network environment on or about October 7, 2025. The firm says it began an investigation right away with the help of cybersecurity experts. That investigation determined that some of its files may have been accessed or acquired without authorization during the event.
The notice describes a long review that followed. The firm says it carefully examined the affected files to learn whose personal information might be in them, and then worked to find current contact information for those people so that it could send notice. By the letter’s account, that work was completed on October 5, 2026, and the firm confirmed that the recipient’s information was potentially impacted. The letter is dated November 10, 2026, and the incident appeared in the California Attorney General’s breach listing with a reported date of November 12, 2026.
The sequence matters. The notice was sent roughly a year after the suspicious activity was first identified. A gap of that length is not unusual when stolen or accessed files must be reviewed document by document, but it also means that people whose information was involved may have gone many months without knowing. During that time, any data that was taken could have been misused without the person being aware of the risk.
The sample letter filed with the state is a template, not a filled-in copy sent to a real person. The sentence that should name the categories of information involved contains a blank merge-field placeholder where the specific data elements would appear. As a result, the filing does not tell us which types of personal information were involved, and this page does not guess. What the letter does say is that the information potentially involved included the recipient’s name together with certain other data elements specific to that individual.
The firm has also not published a total number of people affected. The California listing records the date of the breach and the date it was reported, but it does not give a count. The letter’s list of state regulators suggests that recipients live in a number of different states, but the notice does not say how many people in total received it, and this page does not estimate one.
The notice says the firm has no evidence that anyone’s information has been misused for identity theft or fraud. It also says the firm has taken steps to harden its environment and reduce the risk of a similar incident. The letter does not explain how the intruder gained access, whether any ransom or extortion demand was made, or whether the data was copied, and it does not name an outside group.
Law firms are attractive targets for cybercriminals because they hold concentrated, sensitive information about many people and organizations in a single place. A breach at a firm can affect people who were never its clients, such as parties in a dispute, claimants, former employees and individuals named in documents. If you have had any dealings with the firm, or appear in a matter it handled, you may be among the people who receive notice.
If you receive a notice from Levin, Sedran & Berman, keep it, since it is the best record of what the firm says was involved in your case. The letter you receive should name the specific data elements that apply to you, which the sample on file does not. Use that information to decide which of the protective steps below matter most.
When Did This Breach Occur?
According to the firm’s notice and the California listing, the suspicious activity was identified on or about October 7, 2025. The firm says it finished identifying contact information for affected individuals on October 5, 2026. The notice letter is dated November 10, 2026, and the incident was reported to the California Attorney General on November 12, 2026. The firm has not said how long the unauthorized access lasted.
What Information Was Breached?
The sample notice says the information potentially involved included the recipient’s name along with other personal data elements. The specific categories are left as an unfilled placeholder in the version filed with California, so the exact data types have not been publicly disclosed. Your own notice should list the elements that apply to you. Until you see it, assume that any sensitive information you shared with the firm could be involved, and review your accounts accordingly.
