Understanding Zero-Day Vulnerabilities

A zero-day vulnerability is a security flaw in software that remains unknown to the vendor. These vulnerabilities are particularly dangerous because they are exploited by attackers before developers have a chance to patch them. The term “zero-day” signifies that developers have had zero days to fix the flaw after its discovery.

How do zero-day vulnerabilities differ from other security weaknesses?

• Zero-Day Vulnerability: Exploited before the vendor is aware of it, leaving no time for a patch.
• Known Vulnerability: A flaw that has been identified and possibly patched but still exists on unpatched systems.

Backdoors in Software Systems

Backdoors refer to hidden methods within software for bypassing normal authentication or securing remote access. When these backdoors are discovered and exploited as zero-day vulnerabilities, they can provide attackers with unauthorized access. Backdoors can be intentionally placed for legitimate purposes like maintenance but can become major security risks if found by malicious actors.

Methods Employed by Hackers

Hackers use various techniques to uncover and exploit zero-day vulnerabilities:

• Fuzzing: Automated testing technique that inputs random data into software to identify potential flaws (source).
• Reverse Engineering: Decompiling software to understand its structure and discover hidden vulnerabilities.
• Social Engineering: Manipulating individuals to gain access to confidential information that may reveal software weaknesses.

These concepts are crucial in recognizing why macOS and iOS, despite their robust security measures, remain attractive targets for hackers (source).
