But what can you do to avoid this type of malware and the headache it brings, or to detect and delete it from your Mac once you have been infected? Read on to learn more about this particularly malicious type of malware. Needless to say, a Trojan Horse is bad news for both you and your computer. If your Mac has been infected by a Trojan Horse, the program could do any number of things to the system-from initiating the installation of other viruses or malware programs, to giving a hacker complete remote control of your system. Once the Trojan program has been installed, it goes to work with its true purpose, executing malicious activities that greatly compromise the overall security of the system. Meanwhile, Microsoft's Defender for Endpoint enterprise security platform can be used to detect UpdateAgent's misuse of Apple's PlistBuddy tool for managing PLIST (property list) attribute files for macOS applications.A Trojan Horse, in the computer world, is a potentially devastating type of malware that disguises itself as something desirable in order to be installed or downloaded onto a computer system.
It is encouraging defenders to use its Edge browser on macOS since it supports Microsoft's Defender SmartScreen for blocking malicious websites. Microsoft is interested in Mac malware because more enterprises support non-Windows devices on corporate networks. "More specifically, Adload leverages a Person-in-The-Middle (PiTM) attack by installing a web proxy to hijack search engine results and inject advertisements into webpages, thereby siphoning ad revenue from official website holders to the adware operators."

"Once adware is installed, it uses ad injection software and techniques to intercept a device's online communications and redirect users' traffic through the adware operators' servers, injecting advertisements and promotions into webpages and search results," Microsoft notes.

Adload is capable of opening a backdoor to install other payloads. Microsoft says it has coordinated with AWS to remove malicious links from its cloud services.
UpdateAgent's makers started distributing Adload as a secondary payload in October 2021 when Microsoft raised an alarm it was distributing malware through public cloud providers. "Like many information-stealers found on other platforms, the malware attempts to infiltrate macOS machines to steal data and it is associated with other types of malicious payloads, increasing the chances of multiple infections on a device." "UpdateAgent is uniquely characterized by its gradual upgrading of persistence techniques, a key feature that indicates this trojan will likely continue to use more sophisticated techniques in future campaigns," Microsoft says in a blogpost, cautioning it could follow the trajectory of malware common to Windows.

Then in August, it was improved with changes that allowed the malware to inject persistent code that ran as root in a background process that's invisible to the user. dmg files and tweaked to prevent Gatekeeper from displaying the pop-up warning to users that a file is from an "unidentified developer". In March 2021, it was updated again to fetch compressed. dmg files for macOS from public cloud providers. By January 2021, it could fetch secondary payloads as. Since its discovery between September to December 2020, when it was only an information stealer, the malware has undergone several upgrades to improve persistence allowing it to remain on a system after users sign in to the affected device. It can also use existing user permissions to delete evidence of its presence on a system. While it does require the victim to install an app masquerading as legitimate software, such as a video app or support agent promoted in ad pop-ups, the ability to bypass Gatekeeper controls is significant.

Today, it installs an "unusually persistent" adware threat called Adload, but Microsoft cautions it could be used to distribute other more dangerous payloads in future. Microsoft flagged the malware now as it appears to be under continuous development. Google Drive alternative: Decentralized and encrypted
