What Does Ravenwise Do?
The main activities associated with Ravenwise on an infected Mac include the display of ads and the generation of intrusive pop-ups.
To showcase advertisements, Pirrit variants typically integrate as a browser extension. In technital, terms, the Ravenwise Mach-o binary employs a range of anti-analysis techniques, including anti-disassembly, anti-debug, and anti-vm, to operate covertly and elude security measures.
In addition, Ravenwise employs obfuscation, with the code’s strings and API names being xor encoded and decoded dynamically during runtime. To deter debugging, Ravenwise utilizes the “ptrace” command with the PT_DENY_ATTACH flag (0x1f), terminating the program if a debugger is detected. For virtual environment detection, Ravenwise adopts the following methods: checking the machine model for the presence of the string “Mac” (absent in a VM), assessing the machine’s RAM size, and using the command “ioreg -rd1 -c IOPlatformExpertDevice” to inspect hardware information for specific strings like “VirtualBox, Oracle, VMware, Parallels, qemu,” as per the technical analysis conducted by Palo Alto networks.
How Did Ravenwise Get Installed on Your Mac?
The program typically infiltrates macOS systems through deceptive methods such as posing as a browser extension, often relying on misleading tactics to gain unauthorized access. Users may inadvertently install Ravenwise when downloading and installing freeware or shareware applications from untrustworthy sources.
The program may be bundled with seemingly legitimate software, exploiting users’ haste or oversight during the installation process. In addition, malicious websites and misleading pop-up ads can trick users into clicking on download links, unknowingly initiating the download and installation of the unwanted program.
In some cases, the program may disguise itself as a useful utility, exploiting users’ trust to coax them into installing it.
Is Ravenwise a Computer Virus?
While not classified as a typical computer virus, it is highly recommended to remove the program from your Mac to ensure online security. The program can still pose risks due to its adware characteristics, potential unwanted program activities, and backdoor capabilities.
