![]() ![]() When a Set-UID program runs, it assumes the owner's privileges. Environment Variable and Set-UID VulnerabilityÄescription: Set-UID is an important security mechanism in Unix operating systems.The course is well structured to understand the concepts of Computer Security. The labs were completed as a part of the Computer Security (CSE643) course at Syracuse University. The link contains a document that can be used to set up the VM without any issues. Step 3: Use the Virtual Machine Hard Disk file to setup your VM. These instructions will get you to set up the environment on your local machine to perform these attacks. All the labs are presented in the form of PDF files, containing some screenshots. You can also use a VPN.These labs cover some of the most common vulnerabilities and attacks exploiting these vulnerabilities. Check that your connection is encrypted by looking for a padlock in the URL. If you must use public Wi-Fi, check with the owner of an establishment to make sure you are signing in to the correct internet access point. To avoid becoming a victim of this heist, avoid using public Wi-Fi. If they sign in to an account using a username and password over an unencrypted connection, the app will store that data and give the hacker access. The app then logs all data transmitted over the internet by the people signed into it. People sign into it thinking they are signing into public Wi-Fi. Hackers can give it a name that looks like it belongs to the local establishment. ARP Spoofing: In this technique, a hacker uses an app on his smartphone to create a fake Wi-Fi access point that anyone in a public location can sign into.Log in to business sites directly instead of clicking links in an email. Always check that a website is secure (includes "HTTPS" in the URL). To avoid these scams, don't open emails you don't trust. The user is then asked to input their personal information, which the hacker then gains access to. It may also contain a link to a false business website (made by the hacker) that looks authentic. The email may contain an attachment that installs spyware or a keylogger. Phishing: In this technique, a hacker sends a fake email to a user that appears to be from a person or company the user trusts.Always shred any documents that contain personal information. That is why you should never give your password to anybody, no matter who they claim to be. They may also go dumpster-diving to look for information or try to gain access to a secure room. For example, they make a claim they are from the IT department and tell the user they need their password to fix an issue. Social Engineering: For this technique, a hacker will contact a user and trick them into giving out their password.Make sure to use a combination of letters, numbers, and special characters. To protect against a brute force attack, avoid using simple words as your password. Hackers often use tools that rapidly guess different words from a dictionary to try to guess a password. ![]() This is useful for gaining access to easily-guessed passwords (i.e. ![]()
