What is persistence in security?

Persistence in cybersecurity occurs when a threat actor discreetly maintains long-term access to systems despite disruptions such as restarts or changed credentials. ... After you reboot your system or log off and on again, the stub or malware is retriggered to run again.

What is persistence in malware?

Once malware gains access to a system, it often looks to be there for a long time. This behavior is known as persistence. If the persistence mechanism is unique enough, it can even serve as a great way to fingerprint a given piece of malware.

What is an example of an advanced persistent threat?

ADVANCED PERSISTENT THREAT EXAMPLES

APTs are usually sponsored by nations or very large organizations. Examples of APTs include Stuxnet, which took down Iran's nuclear program, and Hydraq. ... Operation Aurora, which reportedly originated in China, used a zero-day exploit to install a malicious Trojan horse named Hydraq.

How would a piece of malware maintain persistence?

Techniques used for persistence include any access, action, or configuration changes that let them maintain their foothold on systems, such as replacing or hijacking legitimate code or adding startup code. One thing in common between different malware families is that they (mostly) try to persist on the target host.

What is persistence technique?

Persistence consists of techniques that adversaries use to keep access to systems across restarts, changed credentials, and other interruptions that could cut off their access.

Why is persistence so important?

Persistence is a fundamental trait to develop in life because it is closely related to personal development and improvement. ... Without persistence, your ability to grow and develop as a person will be severely restricted, and it will also be the amount of success, wealth and happiness that you can achieve.

Where do I look for persistence?

Another great log source to hunt for persistence is command line history. As we have previously mentioned, command line and terminal history (especially PowerShell) can reveal a huge amount of data which can not only be used by threat hunters, but may also provide a wealth of intelligence about adversaries.

What are rootkits used for?

A rootkit allows someone to maintain command and control over a computer without the computer user/owner knowing about it. Once a rootkit has been installed, the controller of the rootkit has the ability to remotely execute files and change system configurations on the host machine.

What is malware payload?

In the world of malware, the term payload is used to describe what a virus, worm or Trojan is designed to do on a victim's computer. For example, payload of malicious programs includes damage to data, theft of confidential information and damage to computer-based systems or processes.

What advanced persistent threat?

An advanced persistent threat (APT) is a broad term used to describe an attack campaign in which an intruder, or team of intruders, establishes an illicit, long-term presence on a network in order to mine highly sensitive data.

What is phishing in security?

What Is Phishing? Phishing attacks are the practice of sending fraudulent communications that appear to come from a reputable source. It is usually done through email. The goal is to steal sensitive data like credit card and login information, or to install malware on the victim's machine.

How do persistent and non persistent threats differ?

Terms in this set (27) How do persistent and non-persistent threats differ? One plans to gain access, remain undetected and gather information while the other is in and out. What protections can you implement against organized crime threat actors?

What is window persistence?

The persistence trigger is what will cause the payload to execute, such as a scheduled task or Windows service. There are several known persistence triggers that can be used on Windows, such as Windows services, scheduled tasks, registry, and startup folder, and there continues to be more discovered.

What is a registry based persistence?

Registry keys can be added from the terminal to the run keys to achieve persistence. These keys will contain a reference to the actual payload that will executed when a user logs in. The following registry locations is known to be used by threat actors and red teams that use this method of persistence.

What is the backdoor persistence mechanism?

Persistence. To secure the access to a compromised system, attackers use persistence in order to make sure their backdoor remains installed and running across system reboots. This allows intruders to control the infected system in the future and proceed with further exploitation of the target or its infrastructure.
