In the end of January 2020 a large-scale enterprise attack is being launched against targets. Ever since the first samples were launched back in 2012 the virus sample has been updated several different times. Each time a new mechanism is used to intrude onto the victim machines. The newest research gives away readings that the hacking group (of which no further details are known) is using a newly updated release and techniques to intrude onto networks of companies and businesses. The hacking group is sending out phishing business email messages which are sent to the recipients.
OSX.Netwire Trojan is found within IMG files which is the file format used by Mac’s disk imaging software. This is intentional as many email clients, firewalls and filtering systems will check for the attachments in the messages. The IMG files are often considered as trustworthy as they are used to carry software. The samples we looked into will include a file called Sales Quotation which will institute a persistent infection. When the payload file is started this will extract all built-in components. A scheduled task will be instituted which will always run the virus core when the computer is booted.
The main engine will also affect the Registry and Configuration values which will store the addresses of the hacker-controlled servers, as well as any made communications with it. The built-in Trojan component will establish the required connection via the 3012/TCP port. Using a memory scan the analysts have discovered that there are some strings written in Indonesian which is a sign that the hackers may originate from that country.
Symantec security researchers were also able to determine that OSX.Netwire is capable of creating the following files on an infected Mac:
Once this is done, the malware opens a backdoor and connects to a remote location. Furthermore, as long as the connection remains uninterrupted, they could perform all of the actions mentioned below:

- Run or delete files
