iOS and Android juice jacking defenses have been trivial to bypass for years
New ChoiceJacking attack allows malicious chargers to steal data from phones.
About a decade ago, Apple and Google started updating iOS and Android, respectively, to make them less susceptible to “juice jacking,” a form of attack that could surreptitiously steal data or execute malicious code when users plug their phones into special-purpose charging hardware. Researchers at the Graz University of Technology in Austria recently made a discovery that completely undermines the premise behind the countermeasure: They’re rooted under the assumption that USB hosts can’t inject input that autonomously approves the confirmation prompt. Word that juice-jacking-style attacks are once again possible on some Android devices and out-of-date iPhones is likely to breathe new life into the constant warnings from federal authorities, tech pundits, news outlets, and local and state government agencies that phone users should steer clear of public charging stations.
