Written by Tomas Meskauskas on
What kind of application is Disoaq App?
Disoaq App is a PUA (Potentially Unwanted Application) discovered by our researchers while analyzing a rogue installer. Software within this classification usually has undesirable and hazardous capabilities.
Upon investigation, we learned that Disoaq App operates as a dropper for the Legion Loader malware. Note that it could drop other unwanted/malicious programs or browser extensions into systems. The installation setup promoting Disoaq App that we analyzed also included the fake "Save to Google Drive" extension.
Disoaq App overview
Disoaq App is an unwanted application that functions as a dropper, i.e., it can drop (download/install) additional harmful or malicious software onto devices. Disoaq App has been noted dropping the Legion Loader malware.
This loader is likewise designed to cause chain infections. It has been used to introduce various malicious programs into systems, including backdoor-type trojans, data stealers, ransomware, and cryptocurrency miners. It has also infiltrated malicious browser extensions.
Some of the known Google Chrome extensions operated by tracking browsing activity, modifying browsers into HTTP proxies to abuse Internet resources (proxyware), and stealing email contents. Another ability of Legion Loader itself is stealing cryptowallets.
It is pertinent to mention that Disoaq App might be used to drop other malware or malicious extensions. It is also worth noting that the installation setup promoting Disoaq App that we inspected included the fake "Save to Google Drive" browser extension.
To summarize, the presence of software like Disoaq App on devices can lead to multiple system infections, serious privacy issues, financial losses, and identity theft.

Potentially unwanted application examples
Potentially unwanted applications are often disguised as legitimate and useful software. These apps may also offer a broad range of handy functionalities, which are usually fake and nonoperational. However, it must be stressed that functional features alone do not prove the legitimacy or safety of an app/extension.
PUAs tend to have harmful abilities. Prevalent ones include gathering sensitive user data, changing browser settings and generating redirects (browser hijackers), running intrusive advertisement campaigns (adware), etc.
We have investigated thousands of unwanted apps; StealthGuard, Rotq App, Joas App, Weisx App, and Fira App are merely some of our newest articles.
How did Disoaq App install on my computer?
We found an installer containing Disoaq App promoted by a deceptive page. Our research team discovered it while inspecting a Torrenting website that uses rogue advertising networks. Aside from webpages that employ said networks, sites that endorse such software can be accessed via redirects produced by intrusive ads, spam browser notifications, misspelled URLs, and installed adware.
PUAs can also be bundled with ordinary programs. The threat of inadvertently allowing bundled content into the system is increased by downloading from dubious channels (e.g., freeware and third-party websites, Peer-to-Peer sharing networks, etc.) and by treating installations with negligence (e.g., ignoring terms, using "Easy/Quick" settings, etc.).
Additionally, intrusive adverts proliferate unwanted software. When clicked on, some of these advertisements can execute scripts to perform stealthy downloads/installations.
How to avoid installation of potentially unwanted applications?
We strongly recommend researching software before downloading/installing. Another recommendation is to download only from official and verified sources. When installing, it is important to read terms, explore available options, use the "Custom/Advanced" settings, and opt out of all supplementary apps, extensions, tools, etc.
We advise vigilance when browsing since fraudulent and malicious online content usually appears legitimate and harmless. For example, intrusive ads may look innocuous – yet redirect to highly questionable sites (e.g., scam-promoting, gambling, pornography, etc.).
In case of continuous encounters with such adverts/redirects, check the system and immediately remove all suspect applications and browser extensions/plug-ins. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
