Vulnerable Binary Exploitation

Techniques used to exploit weaknesses in executable binaries to execute malicious code.

Understanding Vulnerable Binary Exploitation

Vulnerable Binary Exploitation is a type of cyberattack where hackers exploit weaknesses in compiled executable files (binaries) to execute malicious code, gain unauthorized access, or escalate privileges on a system. These vulnerabilities often arise due to unsafe coding practices, memory corruption issues, or improper input validation.

Real-World Examples of Binary Exploitation

EternalBlue (CVE-2017-0144) – A buffer overflow vulnerability in Windows SMB led to the WannaCry ransomware outbreak.
Heartbleed (CVE-2014-0160) – A buffer over-read vulnerability in OpenSSL, leaking sensitive memory data.
Dirty COW (CVE-2016-5195) – A race condition exploit in the Linux kernel allowing privilege escalation.
Sudo Privilege Escalation (CVE-2019-18634) – A heap overflow vulnerability in Sudo enabled root access for low-privileged users.

Impact of Vulnerable Binary Exploitation

Remote Code Execution (RCE) – Attackers can execute arbitrary commands remotely.
System Compromise – Hackers gain control over servers, networks, and user devices.
Data Theft – Exploits allow stealing credentials, files, and encryption keys.
Malware & Ransomware Deployment – Vulnerable binaries help spread malware automatically.
Denial of Service (DoS) Attacks – Exploits can crash critical applications and services.
