Hajime (Japanese for "beginning") is a malware which appears to be similar to the Wifatch malware in that it appears to attempt to secure devices.[5] Hajime is also far more advanced than Mirai, according to various researchers.[6]


Hajime is a worm according to sources which have placed research on the subject.[7] It appears to have been discovered as early as October 2016.[8]

Later in April 2017, Hajime generated large media coverage as it appeared to be in competition with Mirai.[9] This led to a number of reports which compared and noted that it appeared to have a similar purpose to Linux.Wifatch.[10] It also did not contain any modules or tools for denial of service attacks, but instead only contained methods for extending its reach.[11]

Hand written assembly code specifically for several platforms was also discovered by researchers as well.[12]

Hajime is similar in the method of how it manages to compromise systems to Mirai.[13] Some of the key differences from Hajime is the fact that it uses a peer to peer network for communications compare to Mirai.[14]

What was also noted was the message the malware left on systems it compromised.[15] The message left on systems compromised by Hajime displayed on terminals is shown below.[16]
