How to remove "LamePyre" from Mac?

What is "LamePyre"?

Discovered by malware security researcher, Adam Thomas, the LamePyre virus claims to be communication software called Discord (designed for video gaming communities). In fact, LamePyre is a high-risk trojan capable of opening a system backdoor, capturing screenshots, and then sending them to a remote server.

LamePyre virus

As mentioned above, LamePyre claims to be a Discord app, however, LamePyre developers have not disguised this malware properly - they have simply used Discord's icon. Therefore, once LamePyre is executed, nothing appears on victims' computer screens. Other similar viruses that use this disguise open apps and only then perform malicious actions in the background. Following infiltration, LamePyre captures screenshots and sends them to a remote Command & Control (C&C) server. Thus, cyber criminals can receive various sensitive information. In addition, LamePyre runs a Python script that opens a backdoor called EmPyre. This allows cyber criminals to remotely run commands and perform various actions on the infected system. Therefore, an opened backdoor can lead to various system infections. Furthermore, to keep the code running, LamePyre creates a launch agent called "com.apple.systemkeeper.plist". Recently, EmPyre was used to infect computers with the XMRig cryptominer. Although the miner itself is legitimate, its presence without users' consent can be very frustrating (system performance is reduced significantly). The presence of LamePyre might have serious consequences and should be eliminated immediately. If you have recently opened a Discord app downloaded from an unofficial source, you should immediately scan the system with a reputable anti-virus/anti-spyware suite (such as Combo Cleaner) and eliminate all threats.

The internet is full of viruses that share similarities. Most share the same purpose: to record sensitive information and proliferate other viruses (cause chain infections). These viruses pose a significant threat to your privacy and computer safety. Their presence might lead to significant data and financial loss, or even identity theft. Therefore, remove this malware immediately.

How did potentially unwanted applications install on my computer?

As mentioned above, LamePyre claims to be a Discord application, and thus it is likely that users will download and execute this malware inadvertently. Cyber criminals typically proliferate disguised viruses using peer-to-peer (P2P) networks (such as eMule, torrents, etc.), freeware download websites, free file hosting sites, and other unofficial download websites. They present these viruses as legitimate software. In doing so, criminals attempt to give the impression of legitimacy and trick users into downloading and installing/running malware. Malware is often distributed using spam email campaigns (malicious attachments), trojans (chain infections), and various fake software updaters, which exploit outdated software bugs/flaws or install malware rather than updates.

How to avoid installation of potentially unwanted applications?

To prevent this situation, be very cautious when browsing the internet and downloading/installing/updating software. Avoid using third party downloaders/installers and similar sources. Download your programs from official sources only, using direct download links. Furthermore, think twice before opening email attachments. If the email seems irrelevant or the sender is suspicious/not recognized, do not open any the attached links/files. Keep installed programs updated. To achieve this, however, use implemented functions or tools provided by the official developer. Having a reputable anti-virus/anti-spyware suite is also very important, since these tools can detect and eliminate malware before it does any harm. The main reasons for computer infections are poor knowledge and careless behavior - the key to safety is caution. If your computer is already infected with LamePyre, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate it.
