Anatomy, Head and Neck, Cervical Nerves - NCBI Bookshelf
Cervical nerves are spinal nerves that arise from the cervical region of the spinal cord. These nerves conduct motor and sensory information via efferent and afferent fibers, respectively, to and from the central nervous system. While classified as peripheral nerves, the motor cell body resides in the anterior horn of the spinal cord. There are eight pairs of cervical nerves, denoted C1 to C8 ...
What is C2 in security?
What is C2? Command and Control Infrastructure , also known as C2 or C&C, is the set of tools and techniques that attackers use to maintain communication with compromised devices following initial exploitation. The specific mechanisms vary greatly between attacks, but C2 generally consists of one or more covert communication channels between devices ...
How do attackers use C2 channels?
Once an attacker has an initial foothold, they will usually seek to move laterally throughout the organization, using their C2 channels to beam back information about other hosts that may be vulnerable or misconfigured. The first machine compromised may not be a valuable target, but it serves as a launching pad to access more sensitive parts of the network. This process may be repeated several times until the attacker gains access to a high-value target like a file server or domain controller.
What Can Hackers Accomplish with a Command and Control Infrastructure?
This means that malware introduced through a different channel – say a phishing email or compromised website – can often establish a channel of communication in the outbound direction that would otherwise be impossible. With this channel open, a hacker can carry out additional actions, such as:
How does a P2P botnet work?
In a P2P C&C model, command and control instructions are delivered in a decentralized fashion , with members of a botnet relaying messages between one another. Some of the bots may still function as servers, but there is no central or “master” node. This makes it far more difficult to disrupt than a centralized model but can also make it more difficult for the attacker to issue instructions to the entire botnet. P2P networks are sometimes used as a fallback mechanism in case the primary C2 channel is disrupted.
What is the key to a successful cyberattack?
The key to accomplishing all these tasks is a robust Command and Control Infrastructure or “C2”. What is C2? In this post, we’ll answer that question and look at how adversaries use these covert channels of communication channels to carry out highly sophisticated attacks. We’ll also look at how to spot and defend against C2-based attacks.
How quickly can C2 be detected?
C2 activity is often discovered fairly quickly, and the domains and servers associated with a campaign may be removed within hours of their first use. To combat this, modern malware is often coded with a list of many different C2 servers to try and reach. The most sophisticated attacks introduce additional layers of obfuscation. Malware has been observed fetching a list of C2 servers from GPS coordinates embedded in photos and from comments on Instagram.
Why is command and control important?
Command and Control Infrastructure is essential to attackers – and represents an opportunity for defenders. Blocking C&C traffic or dismantling an adversary’s C2 infrastructure can halt a cyberattack in its tracks. Tackling C2 should never be an organization’s sole focus and should be part of a larger information security program that includes good “cyber hygiene” practices, security awareness training for employees, and well-thought-out policies and procedures. These steps can go a long way towards mitigating the threat posed by command and control infrastructure.
