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.

What is a C2 alert?
Overview. If a C2 detection alert has been triggered this means that the Sophos Endpoint Security and Control product has detected communication with a suspect Command and Control site.
What is C2 malware?
The malware command and control (also called C&C or C2) refers to how attackers communicate and exhibit control of the infected system.Today, the most common protocol used by the malware for the C2 communication is HTTP/HTTPS.
What is C2 connection?
Command-and-control servers, also called C&C or C2, are used by attackers to maintain communications with compromised systems within a target network. These systems include Computers, Smartphones, and IoT’s, .
What is C2 protocol?
What Is a Custom Command and Control (C2) Protocol? A custom C2 protocol is simply a network communication method that does not follow the transmission rules of the well known service associated with the communication port.
What is C2 IP?
One of the most common forms of indicator seen describes a pattern for TCP traffic beaconing to a specific command and control (C2, C&C) server. This idiom describes creating such an indicator in STIX.
What is C2 generic C?
A C2/Generic-C on the endpoint is the ultimate result of this process.This proves that the endpoint had requested a DNS resolution of this malicious URL towards the DNS server. The resolution request from the DNS server was intercepted by the XG firewall and blocked.
What is C2 in security?
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.
What is C2 analysis?
Understanding command and control (a.k.a. C2, CnC or C&C), is critical to effectively detect, analyze, and remediate malware incidents.In the world of malware, C2 is typically used to execute arbitrary commands on a victim system, report the status of a compromise to an attacker, or exfiltrate information.
What is C&C call back?
C&C servers are used by cybercriminals to send commands to systems compromised by malware and received stolen information from the target network. If C&C callback is detected by product, there’s a possibility that the host is infected.
Whats AC and C server?
A command and control server (C&C server) is a computer that issues directives to digital devices that have been infected with rootkits or other types of malware, such as ransomware.
Why is C2 important?
The C2 vertebra is also known as the axis. It is the second cervical vertebra down from your cranium, and is important in protecting your mobility as well as the nerve bundles that affect your sinuses and eyes.
What is C2 anatomy?
The axis is the second cervical vertebra, commonly called C2. It is an atypical cervical vertebra with unique features and important relations that make it easily recognisable. Its most prominent feature is the odontoid process (also know as the dens or peg), which is embryologically the body of the atlas (C1) 1,2.
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 a C2 beacon?
Beaconing is when the malware communicates with a C2 server asking for instructions or to exfiltrate collected data on some predetermined asynchronous interval. The C2 server hosts instructions for the malware, which are then executed on the infected machine after the malware checks in.
What was detected C2 generic A?
C2/Generic-A is the threat name associated with the command and control (C&C) servers used by malware. Note: C2/Generic-A is not detection of a malware payload on an infected machine.The alert indicates that a machine within the network is compromised with malware.
What is C2 generic B?
C2/Generic-B is the threat name associated with remote command and control (C&C) servers used by malware in callhome connections.The network traffic will most likely have resulted from active malware on an infected machine that is attempting to connect to the C&C server.

What is C2 in military?
Command and control, or C2, is defined by the DoD as “the exercise of authority and direction by a properly designated commander over assigned and attached forces in the accomplishment of the mission.”
What are C2 nodes?
Definition. C2 node. Command and Control Junction node.
How do C2 servers work?
Command-and-control servers, also called C&C or C2, are used by attackers to maintain communications with compromised systems within a target network.If the target’s network has liberal outbound or egress firewall rules, the malware will establish a communication channel with the command-and-control network.
