Apple is closing a security gap that allowed outsiders to obtain personal information from locked iPhones without a password, a change that will thwart law enforcement agencies that have been exploiting the vulnerability to collect evidence in criminal investigations.



The loophole will be shut in a forthcoming update to Apple’s iOS software, which powers iPhones.

Once fixed, iPhones will no longer be vulnerable to intrusion via the Lightning port used to transfer data and to charge the devices. The port will still function after the update, but will shut off data an hour after a phone is locked if the correct password is not entered.

The flaw has provided a point of entry for authorities across the US since the FBI paid an unidentified third party in 2016 to unlock an iPhone used by a mass killer in the San Bernardino shooting months earlier.

The FBI sought outside help after Apple rebuffed the agency’s efforts to get it to create a security backdoor for iPhones.

Apple’s refusal to cooperate with the FBI at the time prompted apolitical row, with some saying it pitted the rights of its customers against the broader interests of public safety.

During Donald Trump’s 2016 presidential campaign, he criticised Apple for denying the FBI access to the San Bernardino killer’s locked iPhone.

On Wednesday, Apple framed its decision to further tighten iPhone security as part of its crusade to protect the highly personal information that its customers store on their phones.

The company’s chief executive, Tim Cook, has hailed privacy as a “fundamental” right and skewered both Facebook and one of Apple’s biggest rivals, Google, for vacuuming vast amounts of personal information about users of their free services to sell advertising based on their interests.

During Apple’s battle with the FBI in 2016, Cook called the bureau’s efforts to make the company alter its software a “dangerous precedent”.

“We’re constantly strengthening the security protections in every Apple product to help customers defend against hackers, identity thieves and intrusions into their personal data,” Apple said. “We have the greatest respect for law enforcement, and we don’t design our security improvements to frustrate their efforts to do their jobs.”

It is unclear what took Apple so long to close an iPhone entryway that had become well-known among legal authorities and criminals.

The Israel-based company Cellebrite and the US startup Grayshift sold their services to law enforcement agencies trying to hack into locked iPhones, according to media reports.

Grayshift, founded by a former Apple engineer, markets a $15,000 (£11,000) device designed to help police exploit the security hole in the iPhone’s current software.
