Address space layout randomization (ASLR) is a security technique involved in protection from buffer overflow attacks. Many recent APT (Advanced Persistent Threat) attacks have utilized many different ASLR bypass techniques during the past year, according to Researchers at  FireEye . Many exploits and malware attacks rely on the ability of the programmer to accurately identify where specific processes or system functions reside in memory. In order for an attacker to exploit or leverage a function, they must first be able to tell their code where to find the function or process to exploit.  The goal of ASLR  is to introduce randomness into addresses used by a given task. It involves randomly arranging the positions of key data areas of a program, including the base of the executable and the positions of the stack, heap, and libraries, in a process's address space.  Today a lot of attention is brought to client side exploits especially inside web browsers . Normally the e

Detecting Advanced Persistent Threat with Network Traffic Analysis

A high degree of stealthiness over a prolonged duration of operation in order to do a successful cyber attack can be defined as Advanced Persistent Threat. The attack objectives therefore typically extend beyond immediate financial gain, and compromised systems continue to be of service even after key systems have been breached and initial goals reached. Today's successful targeted attacks use a combination of social engineering, malware, and backdoor activities. Nart Villeneuve and James Bennett (Senior Threat Researcher) from Trend Mirco provide an  ultimate guide for Detecting (APT) Advanced Persistent Threat activities with Network Traffic Analysis , that can be used to identify malware command-and control (C&C) communications related to these attacks, illustrating how even the most high-profile and successful attacks of the past few years could have been discovered.
