If you previously signed up for Experian IdentityWorks in response to the Accellion event, you should have received a notification from Experian March 17, 2022, letting you know that your current Experian IdentityWorks credit monitoring and identity theft protection services have been extended for an additional two years. This means that on the one-year anniversary of your initial enrollment, you will automatically receive an additional two years of credit monitoring and identity theft protection services. UC is extending these services at no cost to you, and no action is required on your part.  The email came from “The University of California” (no-reply@marketing.csid.com).

May 10, 2021 (updated July 1, 2021)

To the UC community:

As we recently disclosed in April and May communications to students, employees and their dependents, and retirees, the University of California (UC) was subject to a cybersecurity attack involving its Accellion file transfer appliance (FTA). This post provides up-to-date information on what happened and what we are doing.

On June 30 and July 1, we sent individual notices to those whose personal information was impacted by the Accellion event where contact information was available. Notifications were sent via USPS mail where we had a current physical address. If the University did not have an individual’s physical address on file but did have an email address, we sent the notification via email. The email came from “The University of California” (no-reply@marketing.csid.com). The University worked deliberately, while taking care to provide accurate information, as quickly as it could. For the latest FAQs, please visit https://bityl.co/7WTa.

What Happened?

On December 24, 2020, UC’s Accellion FTA was the target of an international attack, where perpetrators exploited a vulnerability in the application. Over 100 organizations were similarly attacked, including universities, government agencies and private companies. In connection with the attack, certain UC data was accessed without authorization. We identified on March 29, 2021 that some of this data was posted on the Internet.

After the University discovered the issue, we took the system offline and patched the Accellion vulnerability. We are in the process of transitioning to a more secure solution. The University is cooperating with the FBI and working with external cybersecurity experts to investigate this matter and determine what happened, what data was impacted and to whom the data belongs.

There is no evidence that other University systems were impacted.

To inform and protect the UC member community, the University notified the community via email, hosted interactive workshops at several campuses and posted information about the event and how individuals can protect themselves to its websites. The University also arranged for free credit monitoring and identity theft protection services for employees (current and former) and their dependents, retirees and beneficiaries, and current students through Experian IdentityWorks. Between May 12 and May 14, 2021, these individuals received an email from Experian on behalf of the University reminding them about the available services and providing a unique activation code. The University has established a dedicated call center to answer questions regarding the event and these services.

What Information Was Involved?

While the investigation is ongoing, evidence shows that an unauthorized third party gained access to files that contain personal information relating to members of the UC community, including employees (current and former) and their dependents, retirees and beneficiaries, and students, as well as other individuals who participated in UC programs.

The impacted information may include full names, addresses, telephone numbers, Social Security numbers, driver’s license information, passport information, financial information including bank routing and account numbers, health and related benefit information, disability information and birthdates, as well as other personal information provided to UC. Information provided by students who participated in the 2020 University of California Undergraduate Experience Survey (UCUES) was also impacted and posted to the internet by the threat actor.

We are also separately notifying certain individuals whose UC applications were impacted. For individuals that submitted applications for admission to the 2020-21 school year, their responses to questions in their application were impacted. For individuals that started or submitted applications for the 2021-22 school year, their name, email address and phone number were impacted. Notifications for these individuals will contain information pertinent to them.

What We Are Doing

The University is working to identify and contact the community members whose personal information was impacted. These investigations take time, and we are working deliberately, while taking care to provide accurate information as quickly as we can. By mid-July, we expect to send, through Experian, appropriate individual notifications to those people whose personal information was impacted, where current contact details are available to the University.

In addition to implementing a new file transfer system with enhanced security controls, we are deploying additional system monitoring broadly throughout our network, conducting a security health check of certain systems and enhancing security controls, processes and procedures. We are also reviewing and updating our security policies, procedures, and controls.

What You Can Do

If you have already enrolled in the free credit monitoring and identity theft protection services with Experian, you do not need to re-enroll. For eligible UC community members that have not registered for these services, information about how to register was contained in the update email sent between May 12 and May 14, 2021.

We request that UC community members remain vigilant against threats of identity theft or fraud. You can do this by regularly reviewing and monitoring your account statements and credit history for any signs of unauthorized transactions or activity. If you ever suspect that you are the victim of identity theft or fraud, you can contact your local police.

Additionally, it is also always a good idea to be alert for “phishing” emails or phone calls requesting sensitive information, such as passwords, Social Security numbers or financial account information. These requests often come from a sender pretending to be a company you do business with or a person you know. We also recommend that you use multifactor authentication for your online accounts when offered.

We have also established a dedicated call center available toll free in the U.S. at (866) 904-6220 from 6:00AM to 8:00PM PT on Monday through Friday and from 8:00AM to 5:00PM PT on Saturday and Sunday. Members of the UC community may also send questions to communications@ucop.edu.  

**PLEASE NOTE: If you have already enrolled in the free credit monitoring and identity theft protection services with Experian, you do not need to re-enroll.

Additional Information

To protect against possible fraud, identity theft or other financial loss, you should always remain vigilant, review your account statements, and monitor your credit reports. Provided below are the names and contact information for the three major U.S. credit bureaus and additional information about steps you can take to obtain a free credit report and place a fraud alert or security freeze on your credit report. If you believe you are a victim of fraud or identity theft, you can contact your local law enforcement agency, your state’s attorney general, or the Federal Trade Commission. Please know that contacting us will not expedite any remediation of suspicious activity.


U.S. residents are entitled under U.S. law to one free credit report annually from each of the three major credit bureaus. To order your free credit reports, visit www.annualcreditreport.com or call toll-free at +1 (877) 322-8228.


You may contact the three major credit bureaus at the addresses below to place a fraud alert on your credit report. A fraud alert indicates to anyone requesting your credit file that you suspect you are a possible victim of fraud. A fraud alert does not affect your ability to get a loan or credit. Instead, it alerts a business that your personal information might have been compromised and requires that business to verify your identity before issuing you credit. Although this may cause some short delay if you are the one applying for the credit, it might protect against someone else obtaining credit in your name.

In addition to a fraud alert, you may also consider placing a security freeze on your credit report. A security freeze prohibits a credit reporting agency from releasing any information from a consumer’s credit report without written authorization. However, please be aware that placing a security freeze on your credit report may delay, interfere with, or prevent the timely approval of any requests you make for new loans, credit, mortgages, employment, housing or other services.

A credit reporting agency may not charge you to place, temporarily lift, or permanently remove a security freeze.

To place a fraud alert on your credit report, you must contact one of the credit bureaus below and the other two credit bureaus will automatically add the fraud alert. To place a security freeze on your credit report, you must contact all three credit bureaus below:

Consumer Fraud Division
P.O. Box 740256
Atlanta, GA 30374
+1 (800) 525-6285

Credit Fraud Center

TransUnion LLC
P.O. Box 2000
Chester, PA 19016-2000
+1 (800) 680-7289

To request a security freeze, you will need to provide the following information:

  1. Your full name (including middle initial as well as Jr., Sr., II, III, etc.);
  2. Social Security number;
  3. Date of birth;
  4. If you have moved in the past five (5) years, the addresses where you have lived over those prior five years;
  5. Proof of current address such as a current utility bill or telephone bill; and
  6. A legible photocopy of a government-issued identification card (state driver’s license or ID card, military identification, etc.).

You may also contact the U.S. Federal Trade Commission (“FTC”) for further information on fraud alerts, security freezes, and how to protect yourself from identity theft. The FTC can be contacted at 400 7th St. SW, Washington, DC 20024; telephone +1 (877) 382-4357; or www.consumer.gov/idtheft.
