The Hive ransomware gang claimed responsibility for an attack that hit the systems of Bell Canada subsidiary Bell Technical Solutions.
BTS is an independent subsidiary with more than 4,500 employees, specializing in installing Bell services for residential and small business customers across the Ontario and Québec provinces.
While the Canadian telecommunications company didn’t reveal when its network was breached or the attack happened, Hive claims in a new entry added to its data leak blog that it encrypted BTS’ systems almost a month ago, on August 20, 2022.
The Bell subsidiary warned customers of the possibility of being targeted in phishing attacks following this incident and advised them to monitor their accounts for any suspicious activity.
“We will directly notify any individuals whose private information may have been accessed. Bell Technical Solutions operates independently from Bell on a separate IT system; other Bell customers or other Bell subsidiaries were not impacted,” the company added.
The Federal Bureau of Investigation released some indicators of compromise and technical details associated with Hive ransomware attacks in August 2021.
