An employee of Communauto is reportedly under investigation for the alleged theft of data belonging to several customers of the Quebec car-sharing company. The incident, which involves someone who already had legitimate access to internal systems, is a reminder that a significant share of security risk originates from within organizations.

Key points

  • A Communauto employee is suspected of accessing data belonging to several customers, according to available reports.
  • This type of incident, known as an insider threat, involves a person who already has legitimate access to the targeted systems.
  • Law 25 requires Quebec organizations to keep a confidentiality incident registry and, in some cases, to notify the Commission.
  • Restricting access to only the data required for each role substantially reduces exposure to this type of scenario.

What do we know about this incident?

According to available reports, a Communauto employee is suspected of having accessed and extracted data concerning several customers. No details have been released about the exact nature of the data, its volume, or the motive involved, and an investigation is underway to determine the full scope.

The report does not specify the number of customers affected, the time period involved, or how the access was allegedly used. That lack of detail is not unusual at this stage of an investigation, and we deliberately avoid adding specifics the source does not provide. What is established, however, is the mechanism involved: access that already existed, diverted from its intended purpose.

What exactly is an insider threat?

An insider threat is a security risk posed by someone who already holds authorized access to an organization’s systems or data, whether an employee, a former employee, or a contractor. This type of risk is often harder to detect than an external intrusion, because suspicious behaviour blends in with legitimate activity.

Unlike ransomware or an external hack, an insider threat does not need to force any door open. The person already holds the keys. That is precisely what makes it difficult to spot: without appropriate monitoring in place, unusual access to a customer database can pass for routine work for a long time before anyone notices.

What does this mean for a Quebec SMB or nonprofit?

Any organization that holds personal information in Quebec, regardless of size, is subject to Law 25 and must keep a confidentiality incident registry, assess the risk of harm and, where warranted, notify the Commission d’accès à l’information (Quebec’s access-to-information oversight body) as well as the individuals affected.

Many SMB owners still associate cybersecurity with attacks coming from outside. A case like this is a reminder that insider risk exists as soon as an organization employs staff with access to customer data, which describes nearly every SMB and nonprofit in Quebec. The size of an organization does not exempt it from the obligations set out in the law.

How can exposure to this type of risk be reduced?

No single measure makes this scenario impossible, but several established practices significantly lower its likelihood: restricting access to what each role strictly requires, reviewing that access whenever someone leaves or changes roles, and monitoring unusual activity on systems that hold sensitive data.

None of this requires advanced technology. It mainly calls for management discipline: knowing who has access to what, why, and since when. Periodic review of access rights, combined with regular staff awareness about the value of the data they handle, makes this kind of scenario considerably harder to carry out undetected.

FAQ

Is an insider threat more serious than an external cyberattack?

Not necessarily more serious, but often harder to detect. An external attack usually leaves identifiable technical traces, such as a network intrusion or malware. An insider threat, by contrast, relies on access that is already legitimate, which makes it look like normal activity. The harm to affected individuals, however, depends mainly on the nature and volume of the data involved, not on where the incident originated. For an organization, both types of risk deserve comparable attention, with prevention and detection measures tailored to each.

Does Law 25 also apply to small organizations and nonprofits?

Yes. Law 25 applies to any business or organization, including nonprofits, that collects or holds personal information as part of its activities in Quebec, with no threshold based on size or headcount. This includes the obligation to keep a confidentiality incident registry, assess whether an incident poses a serious risk of harm, and, where warranted, notify the Commission d’accès à l’information and the individuals affected. A small organization is therefore not exempt from these obligations simply because it has no legal department or dedicated data protection officer.

What should an organization do if it suspects a similar incident internally?

The first step is to document what has been observed, without prematurely alerting the person suspected, and then to consult the appropriate internal or external resources to assess the situation before acting. It is then necessary to determine whether personal information is involved, which triggers the obligations set out in Law 25. We also recommend reviewing access logs for the systems concerned in parallel, to establish the actual scope of the incident. Since every situation is different, the precise course of action depends on the organization’s specific context and should be assessed case by case.
