A PHP web shell is a script, written in PHP, that allows attackers to execute commands on a compromised web server remotely. These scripts act as a backdoor, providing attackers with access to sensitive data, server resources, and the capability to escalate their attack.
Cyber attacks have evolved into intricate operations, often executed in multiple stages to achieve maximum impact while evading detection. Multi-stage cyber attacks leverage complex execution chains to mislead victims, bypass traditional defences, and deliver devastating outcomes. For organisations and individuals alike, understanding the mechanics of these attacks is essential for crafting effective defence strategies.
Multi-stage cyber attacks are a formidable challenge, but with offensive security techniques, organisations can move from reactive to proactive defence. By adopting vulnerability assessments, penetration testing, cyber forensics, malware analysis, and reverse engineering, businesses can detect and neutralise threats before they escalate.
SSRF occurs when an attacker exploits a server-side vulnerability to send crafted requests from a vulnerable web server to unintended locations. These requests can be directed to internal services, cloud metadata APIs, or other network resources that would otherwise be inaccessible to external users. Essentially, SSRF enables attackers to leverage the server’s trust in internal resources and APIs to bypass firewalls, access private services, and gather sensitive data.
Security logging involves the systematic recording of events within a system, application, or network. Monitoring, on the other hand, refers to actively reviewing and analysing these logs to detect anomalies or malicious activities.
Software and data integrity failures refer to vulnerabilities that arise when untrusted or unverified components are introduced into software systems. These failures occur when attackers manipulate software or data to exploit weak points, potentially leading to unauthorised control, data breaches, or malicious activities within applications.
