A new malware called Daxin has been identified by security researchers. It is a backdoor that allows the attacker to read and write arbitrary files on the infected system along with other operations. Starting and interacting with arbitrary processes is also a capability the malware possesses. Daxin’s stealth and communication capabilities make it a valuable asset for attackers. Daxin is capable of communicating by hijacking legitimate TCP/IP connections. Incoming TCP traffic and connections are monitored by Daxin to do this communication. Whenever communication patterns are detected, Daxin takes over the connection by disconnecting the user. It then performs a custom key exchange with the remote peer, where two sides follow complementary steps. Receiving commands and sending responses is then enabled after a successful key exchange that opens an encrypted communication channel. Daxin’s use of hijacked TCP connections helps to establish connectivity on networks with strict firewall rules and affords a high degree of stealth to its communications. SOC analysts monitoring for network anomalies may also have a hard time detecting it.
