"Network Layer wants to make changes" Mac virus removal

Learn what Mac virus displays the “Network Layer wants to make changes” popups, what objectives it pursues, and how to remove it from infected Mac.

A growing trend in the malware underground is about building ramified networks of cyber threats, where specific malicious code is deployed in combination with associated infections. Furthermore, the symptoms often change over time, with new adverse effects being added as the pest evolves. The popups plaguing a Mac that read, “Network Layer wants to make changes” demonstrate these subtle interconnections. Numerous users are bumping into these splash alerts off and on while surfing the web. This irksome activity typically originates at the level of web browsers, whether it’s Safari, Google Chrome, or Mozilla Firefox. The dialogs request the victim’s admin credentials under the guise of regular maintenance or update of the Mac’s network configuration. At first sight, it may appear that the attack is a classic social engineering technique aimed at wheedling out the user’s system password. That’s true, but things are bit more complicated than that.

Some closer scrutiny unveils a relation of the “Network Layer wants to make changes” popups with at least two infamous Mac viruses. Most of the affected users have also reported being hit by additional unwelcome entities, including Advanced Mac Cleaner and Chill Tab. These represent different categories of malign Mac code but presumably stem from the same “workshop”. The former is a long-running fake system utility that reports imaginary problems on a Mac in an attempt to dupe the user into buying its license. The latter is an adware that hijacks browsers and drives traffic to bogus search services. The co-occurrence of the popup issue in question with the activity of either one of these culprits is definitely not accidental. This is evidence of the ties mentioned at the beginning of this guide. While exchanging data with their C2 server, these perpetrating apps covertly download an obtrusive browser extension and enable it in the victim’s default web browser without permission.

What’s the point of the “Network Layer wants to make changes” alerts in the context of this symbiosis, though? The most plausible scenario comes down to causing more damage and enlarging the attack surface. Whereas the tactics of the Advanced Mac Cleaner scareware and the Chill Tab browser hijacker don’t match, their authors apparently don’t mind getting the fullest scope of access on the contaminated Mac. This way, they can easily drop and execute arbitrary viruses onto the host, or even remotely lock the machine down and extort money for unlocking it. Beneath the phrase about intended changes, the fraudulent dialogs say, “Enter your password to allow this”. Keep in mind that it’s the highly sensitive admin password that the crooks want. The popups under scrutiny, therefore, are a mechanism for the cybercriminals to gain elevated privileges on a malware-tainted Mac and be able to impact it further.

Ultimately, the right flow of thoughts regarding this predicament should lead the victim to detect and remove the “Network Layer wants to make changes” Mac virus and related malware.
