6. “In 2006, the United States Air Force (USAF) analysts coined the term advanced persistent threat
(APT) to facilitate discussion of intrusion activities with their uncleared civilian counterparts. Thus,
the military teams could discuss the attack characteristics yet without revealing classified identities.
[Bejtlich, 2007]
Bejtlich explains the components of the terminology.
Advanced means the adversary is conversant with computer intrusion tools and techniques and
is capable of developing custom exploits.
Persistent means the adversary intends to accomplish a mission. They receive directives and
work towards specific goals.
Threat means the adversary is organized, funded and motivated.”

8. A common mistake is the assumption that APT based on software only. However, in practice APT
can be based on software, hardware, social engineering or some combinations of the three.
“APT can change it self while moving, in a way similar to the mutation that change it self-according
to the theory of Darwin. In other words, APT is like a Bacteria that can adapt itself to
modern antibiotics in a short time”

11. “The term bot is short for robot. Criminals distribute malicious software (also known as malware)
that can turn your computer into a bot (also known as a zombie). When this occurs, your computer
can perform automated tasks over the Internet, without you knowing it.
Criminals typically use bots to infect large numbers of computers. These computers form a network,
or a botnet.
Criminals use botnets to send out spam email messages, spread viruses, attack computers and
servers, and commit other kinds of crime and fraud. If your computer becomes part of a botnet,
your computer might slow down and you might inadvertently be helping criminals.”

12. "An advanced evasion technique (AET) is a type of network attack that combines several different
known evasion methods to create a new technique that's delivered over several layers of the
network simultaneously. The code in the AET itself is not necessarily malicious; the danger is that it
provides the attacker with undetectable access to the network.
There are currently about 200 known evasion techniques that are recognized by vendor products.
An AET can create literally millions of "new" evasion techniques from just a couple of combinations -
- none of which would be recognized by current intrusion detection system (IDS) vendor products. If
all 200 were used, the permutations would be unlimited.
Here is a very simplified explanation for how an AET works:
Let's say that the words "attack" and "intrude" represent two strings of known malicious code.
When an IDS identifies those strings in a request, the system intervenes and denies entry.
…
13. If, however, "kaarindtuettcr" and "tittnrrakdeuac" were part of a request, the system wouldn't
recognize the code as simply being the well-known malicious strings "attack" and "intrude"
combined and rearranged in a new way. The IDS would not intervene and entry would be allowed. “
Source: Whatis
Please note that according to the current MacAfee research, there are more than 800 million AETs
and the list is growing…
15. AET – Intrusion technic that provides a higher rate of success. In other words, this technic that can
be used to “By Pass” most of the security protections layers that exits today in most of the
organizations.
Botnet – A common attack tool that is used by attacker to implement the attack in practice. As
previously noted above, AET technic may be used to inject the Botnet in a “stealth mode” into the
target organization.
APT's using a sophistic technics, like AET to inject hacking tools, like Botnet's into the target
organization. However, please note that APTs can be inject into the target organization by using
other methods, like scanned documents, telephony commands, and more.

23. “Style 1 — Network Traffic Analysis
This style includes a broad range of techniques for Network Traffic Analysis. For example, anomalous
DNS traffic patterns are a strong indication of botnet activity. NetFlow records (and other flow record
types) provide the ability to establish baselines of normal traffic patterns and to highlight anomalous
patterns that represent a compromised environment. Some tools combine protocol analysis and content
analysis.
Style 2 — Network Forensics
Network Forensics tools provide full-packet capture and storage of network traffic, and provide analytics
and reporting tools for supporting incident response, investigative and advanced threat analysis needs.
The ability of these tools to extract and retain metadata differentiates these security-focused solutions
from the packet capture tools aimed at the network operations buyer.
24. Style 3 — Payload Analysis
Using a sandbox environment, the Payload Analysis technique is used to detect malware and targeted
attacks on a near-real-time basis. Payload Analysis solutions provide detailed reports about malware
behavior, but they do not enable a postcompromise ability to track endpoint behavior over a period of
days, weeks or months. Enterprises that seek that capability will need to use the incident response
features of the solutions in Style 5 (Endpoint Forensics). The sandbox environment can reside on-premises
or in the cloud.
Style 4 — Endpoint Behavior Analysis
There is more than one approach to Endpoint Behavior Analysis to defend against targeted attacks.
Several vendors focus on the concept of application containment to protect endpoints by isolating
applications and files in virtual containers. Other innovations in this style include system configuration,
memory and process monitoring to block attacks, and techniques to assist with real time incident
response. An entirely different strategy for ATA defense is to restrict application execution to only known
good applications, also known as "whitelisting".
25. Style 5 — Endpoint Forensics
Endpoint Forensics serves as a tool for incident response teams. Endpoint agents collect data from
the hosts they monitor. These solutions are helpful for pinpointing which computers have been
compromised by malware, and highlighting specific behavior of the malware.
Because of the challenges in combating targeted attacks and malware, security-conscious
organizations should plan on implementing at least two styles from this framework. The framework
is useful for highlighting which combinations of styles are the most complementary. Effective
protection comes from combining technologies from different rows (for example: network/payload,
payload/endpoint or network/endpoint). The same logic applies to mixing styles from different
columns (different time horizons). The most effective approach is to combine styles diagonally
through the framework.”

34. “1. Statistical Methods. Statistical methods monitor the user or system behavior by measuring
certain variables over time (e.g. login and logout time of each session in intrusion detection
domain). The basic models keep averages of these variables and detect whether thresholds are
exceeded based on the standard deviation of the variable. More advanced statistical models also
compare profiles of long-term and short-term user activities.
2. Distance based Methods. Distance based approaches attempt to overcome limitations of
statistical outlier detection approaches and they detect outliers by computing distances among
points. Several distance based outlier detection algorithms have been recently proposed for
detecting anomalies in network traffic. These techniques are based on computing the full
dimensional distances of points from one another using all the available features, and on computing
the densities of local neighborhoods.

35. 3. Rule based systems. Rule based systems used in anomaly detection characterize normal behavior
of users, networks and/or computer systems by a set of rules.
4. Profiling Methods. In profiling methods, profiles of normal behavior are built for different types
of network traffic, users, programs etc., and deviations from them are considered as intrusions.
Profiling methods vary greatly ranging from different data mining techniques to various heuristic-based
approaches. In this section, we provide an overview of several distinguished profiling
methods for anomaly detection.
5. Model based approaches. Many researchers have used different types of models to characterize
the normal behavior of the monitored system. In the model-based approaches, anomalies are
detected as deviations for the model that represents the normal behavior. Very often, researchers
have used data mining based predictive models such as replicator neural networks or unsupervised
support vector machines.”

39. • We covered the basic APT architecture and its operation.
• Currently, APTs becomes a real threat for most organizations.
• The use of APT allow to a single attacker / a small group of attackers to
achieve high offensive capability.
• We covered a few techniques that can be used to Identify APTs.

The US National Institute of Standards and Technology (NIST) defines that an APT is:
An adversary that possesses sophisticated levels of expertise and significant resources which allow it to create opportunities to achieve its objectives by using multiple attack vectors (e.g., cyber, physical, and deception). These objectives typically include establishing and extending footholds within the information technology infrastructure of the targeted organizations for purposes of exfiltrating information, undermining or impeding critical aspects of a mission, program, or organization; or positioning itself to carry out these objectives in the future. The advanced persistent threat: (i) pursues its objectives repeatedly over an extended period of time; (ii) adapts to defenders’ efforts to resist it; and (iii) is determined to maintain the level of interaction needed to execute its objectives
