Changing characters in a web exploit to their hexadecimal equivalents (e.g., converting spaces to %20 or directory traversals to %2e%2e%2f ).
Static firewall rules are easily bypassed through . If an IDS blocks a connection on port 4444 (a common Metasploit port), the ethical hacker automatically switches the connection to port 80, 443, or 53, which are almost universally left open. In red team exercises, the Meterpreter payload is often configured to "phone home" over standard HTTPS ports, blending in with millions of other secure web connections.
To evade the deep packet inspection (DPI), I wrapped my initial payload in (DoH). Firewalls rarely block DoH to 1.1.1.1 . I injected my reverse shell inside a benign-looking TLS SNI field: Mozilla/5.0 (Windows NT 10.0; ...) Changing characters in a web exploit to their
An IDS monitors network traffic or system logs for malicious activity or policy violations. Unlike firewalls, standard IDS solutions do not block traffic; they alert administrators.
: The attacker specifies the exact path a packet takes through the network. This bypasses standard routing tables and security checkpoints. In red team exercises, the Meterpreter payload is
: Modifying the source IP header of a packet to mimic a trusted internal IP address or an approved external partner.
Encoding data inside standard DNS queries and responses. Because networks must allow DNS traffic to function, this traffic often flows past security boundaries uninspected. Protocol Abuse and Obfuscation I injected my reverse shell inside a benign-looking
Filter incoming and outgoing traffic based on IP addresses, ports, and protocols.
By breaking up TCP headers into several packets, an attacker can sometimes slip past a firewall that doesn't reassemble packets before inspection.
