What is Technique T1041?
Course Description

This course will cover the technique:

> [T1041](https://attack.mitre.org/techniques/T1041/): Exfiltration Over C2 Channel is used by MITRE to describe a tactic that threat actors use to exfiltrate data from a compromised network to a command-and-control (C2) server they control. This technique is often used in advanced persistent threat (APT) attacks, where the attackers seek to maintain persistent access to a network while minimizing their footprint and evading detection.

>Exfiltration to C2 typically involves malware that establishes a connection between the compromised system and the attacker's C2 server, allowing the attacker to access and exfiltrate data from the victim network remotely. The malware may use various techniques to conceal its activity and evade detection, such as encrypting its communications, masquerading as legitimate network traffic, or using steganography to hide data within legitimate files.

>Some standard exfiltration methods to C2 include remote access trojans (RATs), backdoors, and command-line interfaces (CLIs) that allow the attacker to interact with the compromised system and issue commands to exfiltrate data.

> Learn how to detect and mitigate these techniques to protect your organization from this type of attack. Apply what you learn and get the hands-on skills you need in Cybrary's MITRE ATT&CK Framework courses aligned to tactics and techniques used by threat actors.

Success from Our Learners

"Becoming a Cybrary Insider Pro was a total game changer. Cybrary was instrumental in helping me break into cybersecurity, despite having no prior IT experience or security-related degree. Their career paths gave me clear direction, the instructors had real-world experience, and the virtual labs let me gain hands-on skills I could confidently put on my resume and speak to in interviews."

Cassandra

Information Security Analyst/Cisco Systems

"I was able to earn both my Security+ and CySA+ in two months. I give all the credit to Cybrary. I’m also proud to announce I recently accepted a job as a Cyber Systems Engineer at BDO... I always try to debunk the idea that you can't get a job without experience or a degree."

Casey

Cyber Systems Engineer/BDO

"Cybrary has helped me improve my hands-on skills and pass my toughest certification exams, enabling me to achieve 13 advanced certifications and successfully launch my own business. I love the practice tests for certification exams, especially, and appreciate the wide-ranging training options that let me find the best fit for my goals"
