Telus Corp. (NYSE:TU) has opened an investigation into a cybersecurity incident after detecting unauthorized access to a limited portion of its systems, according to reporting from Bloomberg. The Canadian telecommunications company disclosed the breach on Thursday.
A spokesperson from Telus Digital told Bloomberg that, once the activity was discovered, the company acted immediately to address the intrusion and to harden affected systems against further access. The company said it is actively managing the situation and maintaining close monitoring.
Telus, which ranks among Canada’s three largest mobile and broadband providers, said it is notifying customers who have been affected. The company did not provide specifics on the number of systems or customers involved.
An extortion group identifying itself as ShinyHunters told Bloomberg this week that it plans to publish a substantial quantity of data it claims to have taken from Telus in August through a supply-chain attack. The group also said it issued a ransom note to Telus in February requesting payment in Bitcoin; the amount requested was redacted in the note seen by Bloomberg.
The hackers asserted that the data they obtained includes information belonging to Telus customers, which they said comprises technology firms and banks. Telus has not provided a public tally of which customers, if any, were exposed or the scope of data allegedly taken.
Context and corporate action
Telus has communicated that it is taking steps to secure its systems and is monitoring developments closely. A Telus Digital spokesperson emphasized immediate remediation and ongoing oversight following discovery of unauthorized activity.
Claims from alleged attackers
The group calling itself ShinyHunters claims both possession of a large trove of August-origin data and that it issued a ransom demand in February payable in Bitcoin. The purported ransom note reviewed by Bloomberg had the demanded amount redacted.
Promotional note appearing in the original report
The original article included a separate promotional segment about a stock-picking tool called ProPicks AI that evaluates companies including the ticker T using financial metrics. That segment described how the tool ranks stocks by risk-reward and mentioned prior winners, and offered readers the option to see if T is featured in any strategies. This rewrite preserves the factual existence of that promotional content but does not include performance guarantees.
