Exploit.StackPivotBlock is Malwarebytes’ detection name for exploits that attempt to pivot stack pointer to a fake stack
Exploit.StackPivotBlock monitors, detects, and blocks attempts of malicious code to pivot stack pointer to a fake stack. A stack pivot is where an attacker creates fake stack frames in another area of memory. Typically they will alter the value of the extended stack pointer (ESP) to point to an area that they control.
Malwarebytes protects your system(s) by detecting pivoting attempts of the stack pointer and displays the message Exploit Stack Pivoting attempt blocked
