In this blog, we’ll discuss the AdLoad Malware in greater detail, and not just that we will even have a look at some preventive steps, you can take to keep AdLoad malware at bay.
What is AdLoad Malware? How Does It Work?
AdLoad is a well-known Trojan that has been troubling Apple for years now. It was first spotted in 2017 and ever since then, it has also been able to deceive Mac’s notarizing defenses as well.
Here is how it works –
It attacks a system by the way of a backdoor and then downloads and installs PUPs (potentially unwanted programs) or adware. This malware doesn’t just stop there, it can also steal and transmit information about the infected machine. It then sends the stolen information to the remote servers operated by hackers.
Once AdLoad Malware is installed on a Mac, it installs a Man-In-The-Middle web proxy that further hijacks search engine results. It also injects adware for monetary gains.
Why Is AdLoad Able To Get Past XProtect and Gatekeeper
Many strains of AdLoad Malware can get past Mac’s own Malware XProtect for the simple reason that many AdLoad strains don’t match the malware profiles present in XProtect’s database.
Then, there are new AdLoad malware strains that are signed or notarized by Apple developer certificate and they are, therefore, able to pass Apple’s Gatekeeper
Need of The Hour
Apple needs to add further endpoint security controls to Mac devices, the reason being that there are several hundreds of samples of malware like the ones mentioned above that can get past Apple’s built-in security scanners.
