1. What is CIRO? Why would it have my information?
The Canadian Investment Regulatory Organization (CIRO) is the national self-regulatory organization that oversees all investment dealers, mutual fund dealers and trading activity on Canada’s debt and equity marketplaces. CIRO was formed as a result of an amalgamation of the Investment Industry Regulatory Organization of Canada (IIROC) and the Mutual Fund Dealers Association of Canada (MFDA). You received notice of the cybersecurity incident because you were registered at some point in time with IIROC, MFDA or CIRO.
2. How did CIRO obtain my information?
CIRO had a copy of registration data retrieved from the National Registration Database because it manages registration functions for most of the provincial securities administrators. The collection of this information is mandated by the Canadian Securities Administrators under Form 33-109F4 and was submitted to NRD by your current or former dealers. CIRO did not get your registration information from a financial institution or private party.
3. What registration data was impacted?
CIRO’s registration data related to all mutual fund dealer and investment dealer firms and individuals, including Quebec-only mutual fund dealer firms (deemed members) and individuals, was impacted such as:
The information exposed did not include:
4. Why does CIRO have information about my eye/hair colour, height, weight, etc.?
The collection of this information is mandated by the Canadian Securities Administrators under Form 33-109F4 and was submitted to NRD by your current or former dealers. CIRO intends to conduct a renewed review of its data retention policies going forward.
5. How do I find out what specific registration information CIRO has about me that was exposed?
You may view the information CIRO holds about you by accessing your National Registration Database (NRD) account. This is the information that has been compromised by the incident.
6. How is CIRO notifying the affected individuals?
We began sending letters to all affected individuals beginning September 9 to advise them that their personal data was impacted, and provide guidance on next steps including how to sign up for free credit monitoring and identity protection services.
We will contact affected individuals through the information they provided in the National Registration Database (NRD). If an email address was provided, you will get an email from either ciro@cyberscout.com OR ciro@m.cyberscout.com. Otherwise, you will be sent a letter in the mail. Emails will be distributed in a few days, and mailed letters may take approximately 3–7 business days to arrive.
7. What steps are being taken to protect and support affected individuals?
We are providing free credit monitoring and identity theft protection to all impacted individuals for a period of 2 years with TransUnion and Equifax. A dedicated phone line is also available to address any questions or concerns.
8. I have received a notification informing me there is activity on the dark web about to me.
To date, there is no evidence of CIRO-held data posted on the dark Web. The dark web monitoring feature allows you to be notified when your personal information is found on the dark web, as a result of any breach. We are continuing to monitor the dark web for any suggestion that data from CIRO systems specifically has been published.
9. Is two years of credit monitoring enough given the type of data that was exposed?
As a precautionary measure and to help detect possible misuse of your information, CIRO is providing two years of credit monitoring and identity protection services. Importantly, coverage is being provided through two Canadian credit bureaus – Equifax and TransUnion – not just one. The package also includes dark web monitoring, which will alert you if your information is ever detected online at any point in the future, whether from this incident or elsewhere.
10. I’m an advisor and I’m concerned that my clients may be more vulnerable to scams or impersonation attempts because of the breach of my personal information. Should I be worried?
We understand these concerns. However, based on our review, there is no current evidence that client information is connected to the compromised advisor information in a way that would increase the risk of impersonation or targeted scams.
As a general best practice, we encourage advisors and clients to remain vigilant and follow standard precautions, such as independently verifying any unexpected requests for information or money, and reporting suspicious communications to their firm or to the appropriate authorities. CIRO has several articles and tip sheets that can be used as resources for you and your clients.
11. I am a former registrant with CIRO and have not been registered in a long time. Why do you still have my data?
CIRO collects registration information in order to deliver effective regulation of individuals in the investment industry. CIRO intends to conduct a renewed review of its data retention policies going forward.
12. Was the NRD system breached?
No. The NRD system was not breached. The impacted data relates to registration information held at CIRO.
13. When should I expect to receive a notification letter?
We began sending letters to all affected individuals beginning September 9. Emails should be received in a few days, and mailed letters may take approximately 3–7 business days to arrive.
14. Has the incident impacted all CIRO registrants, or only a subset of them?
The incident affected a significant number of registrants of CIRO members, both current and former, but not all.
15. Who will be sending the letter – will CIRO be sending a separate letter, or TransUnion, or both?
Each affected individual will receive one letter that will be signed by CIRO and sent by TransUnion on our behalf.
16. Are individuals going to be notified by email, by letter in the mail, or both?
If you have an email address on file in NRD, you will receive an email from either ciro@cyberscout.com OR ciro@m.cyberscout.com. Those without an email address on file will receive a letter mailed to your residential address.
17. I am a former registrant, i.e. I am not currently registered with a CIRO Member. What happens if the email address or residential address on file for me in NRD is out of date? How will I be notified? And are there privacy concerns I should be aware of if our letters or emails are sent to another address?
We are tracking email bounce-backs and mailed letters marked “return to sender”, and will follow up to determine alternate methods of communication where necessary.
Please note that the notification letters include only the recipient’s name and no additional personal information. Furthermore, only the individual identified in the letter will be able to use the access code. To create an account with the credit bureaus, you must answer security questions related to your personal banking and credit history, information that only you would know, in order to proceed.
18. I am a current or former registrant and have not received a letter from TransUnion / CIRO – either by email or mailed letter. What should I do?
If you haven’t received a letter, please complete the Cyber Incident form. Note that due to privacy considerations, if you are unable to verify your identity, we may not be able to help you.
19. Given the information that was exposed, are the risk mitigation steps being taken sufficient to protect the impacted individuals?
We sincerely apologize for this incident and any concern it may have caused you. What we’re offering in terms of risk mitigation is considered best practice. The steps that will be set out in the notice letter are as follows:
20. Will non-Canadians/foreign registrants be able to avail of the credit monitoring and identity-theft protection services?
Individuals will be able to benefit from the services if they have a Canadian credit bureau file. This would be the case even if they’re currently out of the country. If they do not have a Canadian credit bureau file, they won’t be able to use the services. The authentication questions they will be asked during enrolment are based on what’s in their Canadian credit file (e.g. confirming what Canadian bank they have a loan with, if any.) If you are unable to access any services, please contact MembershipServices@ciro.ca.
21. Do I need to register for only TransUnion or only Equifax, or both?
We have provided both services for individuals. Please open accounts with both credit bureaus.
22. Am I able to register for services if I’ve signed up previously and have a past account?
A TransUnion representative should be able to assist with deactivating your previous monitoring service. You may reach out to the dedicated support line in your notification letter and specify this with the agent. The agent can then assist you by canceling your current monitoring service to allow you to sign up for the most recent one.
23. Why do I get an error when trying to register for services? I'm being asked to contact a 1.800 number.
If you are not able to complete your authentication questions with the anticipated responses, the system will generate an error message and prompt you to contact an agent. The agent will be able to complete the authentication process with you, allowing you to register for services.
24. What about instances where passport information has been exposed. Do those individuals need to do anything extra?
All impacted individuals should follow the risk-mitigation steps outlined in the letter. If you provided your passport number in NRD, it does not need to be replaced. However, if you become aware that your passport number is being misused, you should report it to the government immediately. The identity theft insurance services provided can assist you with this process.
25. Hasn’t TransUnion recently experienced a data breach? How safe is it for individuals to create an account there?
There have been media reports that TransUnion itself was breached recently. This relates to a TransUnion USA vendor breach. The Canadian TransUnion credit bureau was not breached. You are not putting your data at risk by registering for the credit monitoring services that will be offered.
26. If someone has questions about the letter or the breach, whom should they reach out to?
The letter you received includes a dedicated call centre number. Please note that CIRO staff may not be in a position to provide additional information; as far as possible, please direct your inquiries to the call centre.
