Islamabad: Computers are being compromised when victims are tricked into opening emails that include “special crafted” Microsoft Word document attachments that contain coding that lets the hackers exploit a vulnerability using a malformed graphics image embedded in the file itself.
A zero-day (or zero-hour or day zero) attack or threat is an attack that exploits a previously unknown vulnerability in a computer application, meaning that the attack occurs on “day zero” of awareness of the vulnerability. This means that the developers have had zero days to address and patch the vulnerability. Zero-day exploits (the software and/or strategies that use a security hole to carry out a successful attack) are used or shared by attackers before the developer of the target software knows about the vulnerability.
