March 12 (Reuters) - Canadian telecommunications and

business services firm Telus ( TU ) is investigating a

cybersecurity incident involving unauthorized access to some of

its systems, a company spokesperson said on Thursday.

The ShinyHunters hacking group told Reuters in a message it

stole at least 700 terabytes of data from Telus ( TU ).

All business operations within the company "remain fully

operational, and there is no evidence of disruption to customer

connectivity or service," the spokesperson said in a statement

provided to Reuters.

Telus ( TU ) is working with cyber forensics experts to support its

investigation and with law enforcement, and is "notifying

impacted customers, as appropriate," the spokesperson said.

The statement did not address what kind of data was stolen

or how much.

Samples of the data shared by the hacking group with Reuters

suggest the stolen data includes information related to at least

two dozen companies that included personally identifiable

information, call data and recordings, FBI background check

information and source code spanning multiple business divisions

within the business services and telecommunications company.

Reuters has not verified the authenticity of the data.

ShinyHunters has been linked to a string of hacks targeting

major companies around the world. Dutch telecom Odido said last

month that the company believed the group's claims that it was

behind a recent hack that exposed personal information from more

than six million accounts. The group has also targeted data

associated with PornHub, Wynn Resorts, and many other

companies.
