Blackberry was infected with a new virus that is being tracked by security firm AVG.
The bug, first detected by AVG, affects the phone’s SIM card and is able to hijack the phone for data or use the phone in ways it normally would not.
Blackberry said it has been unable to identify the bug’s origin and was working with a third-party to investigate.
BlackBerry said the virus is still being actively investigated and will be reported to the UK authorities as soon as possible.
The UK’s Mobile Networks Agency said the SIM card had been taken from the Blackberry 710, a phone with a 4G SIM card.
Blackberry said the phone had not been used in a public place, and no one at the Blackie Mobile facility was aware of any health risk.
It also said that the virus was not being transmitted by a Bluetooth-enabled device.
Aviation experts said the new virus could be a threat for the industry, which relies on high-speed cellular communications.
The UK government has said it is investigating the matter and said it was investigating the extent of the risk.
BlackBerry said in a statement: “We are aware of an ongoing incident in the UK, where Blackberry has suffered a serious breach of security.
We are currently working with the UK’s mobile networks agency, to investigate the matter.”
The firm said it had not detected any other incidents in the country.
