IOCs act as flags that cybersecurity professionals use to detect unusual activity that is evidence of or can lead to a future attack. There are several different types of IOCs. Some include simple elements like metadata and others are more complex, such as complicated code of malicious content...
Indicators of attack (IoAs)are behaviors or patterns used toidentify a cyberattack that is in progress. An IoA identifies the intent and the techniques used in carrying out malicious activity on a system or network. So, the state of the attack is the most significant difference between the tw...
Indicators of Compromise (IOCs) are examples of abnormal or malicious behavior reflecting the intrusion of an external user or program within internal organizationnetworks. IOCs help network administrators map a threat actor’s attack route and determine the impact of the compromise. While users somet...
these red flags aren’t always easy and obvious to detect. Some of these IOCs can be as small and as simple as manipulating metadata elements. Or they can be incredibly complex malicious code and content stamps that slip through the cracks. Analysts must have a good understanding of what’...
When a malware attack takes place, traces of its activity can be left in system and log files. These IoCs present the activity on your network that you may not otherwise be able to see in real-time and that could suggest potentially malicious activity is taking place. If a security breach...
Uncover the fundamentals of Indicators of Compromise (IOCs) in Cyber Security. Explore common types, differences from Indicators of Attack, and best practices.
Loader malware is a category of malicious software designed to download and install additional malware onto a compromised system. Often used as the initial stage of a multi-tier attack, loaders enable threat actors to deploy a variety of secondary payloads, such as ransomware, banking trojans, or...
Usually, a key element of an attack is the email’s content. Therefore, emails can have malicious attachments or contain code embedded in hyperlinked URLs which make them an important IOC. These attachments often have an MD5 IOC that has been reported in OSINT channels. ...
The key to early detection of advanced operations such as the SolarWinds attacks is in leveraging Indicators of Behavior (IOBs) to level-up to a more efficient and effective Operation-Centric approach to detecting the whole of an attack as opposed to res
Event Stream Processing (ESP) has been a central component of CrowdStrike Falcon®’s IOA approach since CrowdStrike’s inception. In this post we’ll take a closer look at ESP — along with its utility and challenges — in an endpoint protection platf
