Zero Day Exploits Explained | Nicole Perlroth and Lex Fridman

TL;DR

Zero-day vulnerabilities refer to undisclosed software bugs that hackers exploit before they are patched. They can be used to remotely gain control of devices, making them highly valuable to spy agencies and governments.

what is a zero-day vulnerability and then um a zero-day exploit or attack so at the most basic level let's say i'm a hacker and i find a bug in your iphone ios software that no one else knows about especially apple that's called a zero day because the minute it's discovered engineers have had zero days to fix it if i can study that zero day i could...

Key Insights

• 🥳 Zero-day vulnerabilities allow hackers to exploit undiscovered software bugs before they are patched.
• 🥳 Zero-day exploits can remotely gain control of devices, capturing sensitive information without the user's knowledge.
• 🥳 There is a lucrative market for zero-day exploits, particularly for spy agencies and governments seeking to monitor critics or dissidents.
• 🥳 The value of zero-day exploits can vary, with Android exploits currently fetching higher prices than iPhone exploits.
• 🥳 Zero-day exploits can target both specific individuals and large populations, depending on the attacker's objectives.
• 🥳 Governments in the Gulf region are known to pay top dollar for zero-day exploits to monitor their own citizens and critics.
• 🥳 The discovery of zero-day exploits in the wild has revealed attacks targeting specific populations, such as the Uyghurs.

Questions & Answers

Q: What is a zero-day vulnerability?

A zero-day vulnerability is a software bug that is unknown to developers and can be exploited by hackers before it is fixed. It gives hackers an advantage as developers have had "zero days" to address the issue.

Q: How are zero-day exploits created?

Zero-day exploits are developed by studying and understanding the zero-day vulnerabilities. Hackers write programs to take advantage of these vulnerabilities, allowing them to gain unauthorized access to devices.

Q: Why are zero-day exploits valuable to spy agencies and governments?

Zero-day exploits that can remotely exploit devices without the user's knowledge have immense value to spy agencies and governments. They can be used to monitor critics, dissidents, or potential threats, providing insight and control over their activities.

Q: Are iPhone exploits more valuable than Android exploits?

The value of zero-day exploits depends on various factors. While iPhone exploits were highly sought after, the prices have shifted, and currently, remote Android zero-day exploits fetch higher prices due to the larger market share of Android devices.

Summary & Key Takeaways

• A zero-day vulnerability is a software bug that is unknown to developers, giving hackers a chance to exploit it before it is fixed.

• Hackers can create zero-day exploits, programs that take advantage of these vulnerabilities to gain unauthorized access to devices.

• Zero-day exploits have significant value, especially if they can remotely target devices without the user's knowledge, making them highly sought after by governments and spy agencies.
