“At a briefing by security staff this year, he said he got some advice on how to help keep his cellphone secure.
Step One: Turn off phone.
Step Two: Turn it back on.
That’s it. At a time of widespread digital insecurity it turns out that the oldest and simplest computer fix there is — turning a device off then back on again — can thwart hackers from stealing information from smartphones.”
“Typically, once hackers gain access to a device or network, they look for ways to persist in the system by installing malicious software to a computer’s root file system. But that’s become more difficult as phone manufacturers such as Apple and Google have strong security to block malware from core operating systems, Ziring said.
“It’s very difficult for an attacker to burrow into that layer in order to gain persistence,” he said.
That encourages hackers to opt for “in-memory payloads” that are harder to detect and trace back to whoever sent them. Such hacks can’t survive a reboot, but often don’t need to since many people rarely turn their phones off.”
