Poorly implemented cryptography can often be the source of an attack. In this video, you’ll learn about downgrade attacks, SSL stripping, and hash collisions. << Previous Video: Application Attacks Next Video: Password Attacks >> Cryptography is a technology we use many times a day. But we often don’t even think about what’s happening behind the […]

Our applications can be the weakest links in our security armor. In this video, you’ll learn about privilege escalation, directory traversal, and more. << Previous Video: Malicious Code Next Video: Cryptographic Attacks >> An injection attack is a very common way to attack an application because an attacker can easily add additional malicious code to

An attacker often writes their own software to exploit a vulnerability. In this video, you’ll learn about malicious code and how it has been used to gain access to some of the largest networks in the world. << Previous Video: Replay Attacks Next Video: Application Attacks >> As we’ve already discussed in this course, attackers

Some attacks can reuse our network communication to gain unauthorized access. In this video, you’ll learn about pass the hash, session hijacking, and other ways to implement a replay attack. << Previous Video: On-path Attacks Next Video: Malicious Code >> A common flow of network traffic is from a client to send information to the

An on-path attack allows an attacker to intercept and redirect critical network traffic. In this video, you’ll learn about the processes used to implement an on-path attack. << Previous Video: Wireless Attacks Next Video: Replay Attacks >> An on-path attack allows an attacker to sit between two devices and watch all of the traffic go

Wireless networks are susceptible to many different types of attacks. In this video, you’ll learn about deauthentication attacks, RF jamming, and more. << Previous Video: DNS Attacks Next Video: On-path Attacks >> Let’s say you’re on a wireless network browsing the internet, and then suddenly, you’re disconnected from the wireless network. There’s no warning, no

Our DNS services are critical components on our networks, and attackers can use these services as attack vectors. In this video, you’ll learn about DNS spoofing, domain hijacking, and URL hijacking. << Previous Video: Denial of Service Next Video: Wireless Attacks >> We rely on our domain name services or our DNS servers to provide

An attacker may only be interested in disabling services on your network. In this video, you’ll learn about many different forms of denial of service attacks. << Previous Video: Physical Attacks Next Video: DNS Attacks >> A denial of service occurs when an attacker forces a service to fail. This is an intentional process where

Some attacks take advantage of vulnerabilities in our physical world. In this video, you’ll learn about brute force attacks, RFID cloning, and environmental attacks. << Previous Video: Other Malware Types Next Video: Denial of Service >> In this course, we’ve talked a lot about technology and how attackers can circumvent different aspects of our operating
