SC_GETPC_CALL
What it means
x86 CALL $+5 instruction sequence that obtains the current instruction pointer.
Why it fires
Shellcode needs to know its own memory address to locate encoded payloads. CALL $+5 followed by POP is a common way to get the program counter (PC). This pattern is unusual in normal documents.
