After exploiting a vulnerability, a cyberattack can run malicious code, install malware, and even steal sensitive data. Vulnerabilities can be exploited by a variety of methods, including SQL injection, buffer overflows, cross-site scripting (XSS), and open-source exploit kits that look for ...
Examples of Remote Code Execution Buffer overflow A threat actor could overflow a memory buffer using a simple string-copying or print function, which works because the function didn't check the buffer length before executing it. The attacker then overwrites the return address and points it to ...
Some of the most common attack vectors are buffer overflows, phishing, malicious websites and direct network attacks that exploit protocol flaws. The most infamous cases of zero-day exploits include the MOVEit and Stuxnet vulnerabilities. Zero-day exploits are code vulnerabilities and loopholes that ...
Moreover, phishing is often used to gain a foothold in corporate or governmental networks as a part of a larger attack, such as anadvanced persistent threat(APT) event. In this latter scenario, employees are compromised in order to bypass security perimeters, distribute malware inside a closed ...

Note that this function makes us vulnerable to a DoS attack, where a server can send part of a frame and then swallow the rest. We should add support for socket timeouts here at some stage. """ # TODO: Fix DoS risk. if not length: return memoryview(b'') buffer = bytearray(length...
If the // buffer overflows, the entire contents of the buffer are discarded, the lpBytesReturned // parameter contains zero, and the ReadDirectoryChangesW function fails with the error // code ERROR_NOTIFY_ENUM_DIR. // We can force the error by increasing the amount of time between calls...
