A Phorpiex malware infection begins with the delivery of a dropper. This dropper is distributed to systems via various methods, including:
Once the dropper is installed and running on a system, it communicates with the Phorpiex command and control (C2) servers. These servers deliver the Phorpiex malware and additional uploads or modules that provide particular functionality. A new update in 2021 called Twizt enables the malware to operate in peer-to-peer (P2P) mode in the absence of active C2 servers.
The Phorpiex botnet is primarily used as a means of generating revenue for its operators. Some of the ways in which the botnet’s reach is monetized include:
Phorpiex is a large, well-established botnet. As a result, it is used for a few different purposes, including delivering malware and sending spam emails.
The Phorpiex botnet has been used to deliver a variety of different malware variants. Some of the types of malware delivered by the botnet include:
This ability to deliver additional malware makes the Phorpiex a significant, dangerous threat. Once the botnet has a foothold on an infected computer, multiple attackers may be provided with access to the system, and it may be infected with various types of malware.
The other primary use of the Phorpiex botnet is as a mailer. Phorpiex has been known to send a variety of spam emails, including:
The Phorpiex malware can be delivered to a system via different means. Some security best practices that help to protect against Phorpiex infections include:
