DOIT - Canadian IT company allowed leak of its own clients. Listed by ragnarlocker Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Ransomware groups continue to target technology providers as a way to reach multiple downstream clients at once, turning a single compromise into a broader supply-chain problem. In early September 2023, the Canadian IT firm DOIT appeared on a ransomware leak site, adding another entry to a long list of service companies whose internal systems have been claimed as breached.

Public reporting states that DOIT was listed by the RagnarLocker ransomware group, which asserts it exfiltrated internal files. The number of people affected remains unknown, and independent confirmation of the full scope has not been published. For clients and partners of an IT provider, even an unverified claim of this kind raises practical questions about what may have been exposed and what steps to take next.

Breaking down the breach

According to available records, DOIT was listed on the RagnarLocker ransomware leak site on or around 2 September 2023. The group claims to have stolen internal data in a ransomware attack. Public detail does not include the precise date of initial access, the intrusion method, the volume of data taken, or whether any ransom demand was paid or refused. The number of individuals or client organisations affected is listed as unknown. What is stated is that internal files were described as exfiltrated and that the firm, characterised as a Canadian IT company, was accused by the group of having allowed a leak of its own clients’ information. Beyond the leak-site listing itself, no further technical indicators or forensic findings have been released in the material provided.

The group behind it: ragnarlocker

RagnarLocker is a ransomware operation that has been active for several years and is known for double-extortion tactics: encrypting systems while also copying data and threatening to publish it if payment is not made. The group has historically focused on mid-sized and larger organisations across multiple sectors, often using compromised remote-access tools, stolen credentials, or unpatched vulnerabilities to gain an initial foothold. Once inside, operators typically move laterally, escalate privileges, and stage data for exfiltration before deploying ransomware. RagnarLocker has maintained a dedicated leak site where it posts victim names and, in some cases, sample files to pressure organisations. In this instance the group claims to have stolen internal data from DOIT; that claim originates from the leak-site listing and has not been independently verified in the public record summarised here. No additional statements attributed specifically to this victim beyond the listing itself are documented in the available facts.

DOIT and its sector

DOIT is described as a Canadian IT company. Organisations of this type commonly provide managed services, infrastructure support, software development, cloud administration, or related technology consulting to business clients. Because such firms often hold credentials, network diagrams, configuration data, support tickets, and sometimes copies of client systems or backups, a compromise can have effects that extend beyond the provider itself. Clients may rely on the IT company for security monitoring, patching, or privileged access; any breach therefore carries potential supply-chain implications. Public background on the sector makes clear why attackers view technology service providers as high-value targets: a single successful intrusion can yield information about many customer environments at once. The listing of DOIT does not by itself establish negligence or specific security failures; it simply places the organisation among those claimed by RagnarLocker.

The information in question

The facts state that internal files were exfiltrated in a ransomware attack. No further breakdown of file types, record counts, or named data categories has been disclosed. Exact contents remain unconfirmed. In general, an IT services firm may hold employee records, client contact lists, contracts, technical documentation, authentication material, project files, and correspondence. Whether any of those categories were among the material RagnarLocker claims to possess is not established in the public summary. Readers should treat the exposure of specific personal or client data as possible rather than proven until more detailed confirmation appears.

What's at stake

For individuals whose information may have been held by DOIT or its clients, the practical risks include targeted phishing, social-engineering attempts that reference genuine internal details, and longer-term identity or credential misuse if personal data was present. For client organisations, the concerns centre on potential exposure of network information, credentials, or proprietary material that could assist further attacks. The IT provider itself faces operational disruption, reputational damage, and the cost of investigation and remediation. Because the scale of the incident and the precise data types remain unknown, the concrete impact on any given person or company cannot yet be measured. The absence of confirmed numbers does not eliminate risk; it simply means affected parties must proceed on the assumption that internal material may have left the organisation’s control.

What to do if you're exposed

If you are a client, employee, or partner of DOIT, treat the claim seriously until more information is available. Monitor accounts for unusual activity, enable multi-factor authentication where it is not already in use, and be cautious of unsolicited messages that reference the company or its services. Consider changing passwords for any systems that may have been managed or accessed through the provider. Keep records of any suspicious contact. You can also run a free exposure scan of your email address to check whether your information has already appeared in known breach data sets. Stay alert to official updates from DOIT or relevant authorities rather than relying solely on ransomware-site claims.
