Warning for millions of Samsung phone owners – don’t ignore new alert | The Sun
SAMSUNG has overhauled its security system, replacing it with one that prevents so-called 'zero-click' exploits lurking in malicious image files.
The new security system, called Samsung message Guard, will catch threats as they reach the device in a message and stop them before they do any damage, the Korean tech giant announced.
Zero-click exploits are cyber threats that don't require any interaction with the user.
They often involve sending the target a message or file with malicious code that gives the attacker access.
They are particularly dangerous, and hard to spot for the average smartphone user.
“Samsung Message Guard automatically neutralises any potential threat hiding in image files before they have a chance to do you any harm,” Samsung explained.

“When an image file arrives, it is trapped and isolated from the rest of the device.
"This prevents malicious code from accessing your phone’s files or interacting with its operating system.
"Samsung Message Guard checks the file bit by bit and processes it in a controlled environment to ensure it cannot infect the rest of your device."
While there's no evidence of Android devices being particularly susceptible to these types of attacks, Samsung said it is best to act pre-emptively.
