In the snippet below, the decryptor makes the text section writable and executable, by assigning a new protection to it.

But one widely-used software distribution tool for MacOS applications goes to great lengths to avoid being blocked as bundleware using a number of anti-forensics techniques that are more common in malware code.

The installer is from a legitimate company, which claims to reach over 1 billion users per month with its various downloaders and adware platforms.

Its developers went as far as to embed a full backdoor-like component into the installer that allows remote injection of new code into the installer granting it capabilities that extend far beyond what one might expect from a piece of installation software.

The power given to the installer practically enables full control over the target system.

Even if this was done so that the company behind it would have advanced analytics or the ability to push any third-party software it wants, given the amount of power it aggregates, what happens if this power is abused.

The developers have been contacted by researchers, but have shown no interest in changing what they see as a feature of their installer, as long as it allows them to monetize the installations of their software.

One of the reasons often given is the desire to improve the overall user experience of software installation.

Developers or websites distributing freeware (such as free games) or software based on open source components may not be able to charge for the applications, but they can capture some revenue by teaming with a third-party installation tool.

Once the target application is installed, users often encounter undesirable consequences, such as installed browser hijackers that modify the search engine for their web browser.

In some cases, these inject messages for scare-ware removers that prompt the user to pay for the removal of non-exist threats.

In 2019, starting with macOS 10.14.5 (Mojave), Apple began requiring application developers to submit their code for notarization, and blocking applications without notarisation or with revoked developer signatures by macOSs Gatekeeper.

But bundleware installers may not get flagged as suspicious in the notarization process.

But the bundleware package we examine here, already blocked by a number of endpoint protection tools as a potentially unwanted application, adopts many anti-forensics and counter-detection techniques that have in the past been found mostly in malware.

Some other installers were found to be signed by RuiQing Software Technology Beijing Inc.

The dynamic linker then initializes the Objective-C runtime, and then calls the programs main () function.

Contrary to that, lazy classes (classes without load method) do not have to be realized immediately, but only when they receive a message for the first time (hence the term lazy).

It enlists only two non-lazy classes: ListedUpaithric and ARCLite.

For example, in another sample this class is called HoundingHusky.

However, at first glance the load method of the ARCLite class contains no valid code, because it is located within the text section of the executable which is encrypted.

Once run, the load method will take a 32-byte XOR key hard-coded in the body and then use that key to decrypt the text section (around 15KB in size) of the executable, including the load method of the ARCLite class.

The virtual address of this anchor is used to describe the virtual address and virtual size of the encrypted text section.
