Palo Alto Networks is proactively trying to safeguard its customers from attacks however possible. By leveraging its Next-Generation Firewall as sensors on the perimeter to detect malicious payloads and attack patterns, Unit 42 researchers are able to hunt down the menaces out there on the network, be they known or not.
Unit 42 researchers have taken a closer look at four Mirai variants from two recently discovered campaigns leveraging command injection vulnerability exploits that reveal a familiar IoT attack pattern.
While this generic approach allows researchers to observe the entire killchain and even acquire the malware binary from the attack, this post-exploitation heuristic does have its caveat: the traffic fingerprinting.
