How to stop the dev-defense.com site from displaying notifications (ads)

Also Known As: Ads by dev-defense.com
Damage level: Medium

What kind of page is dev-defense[.]com?

Dev-defense[.]com is a rogue webpage designed to promote dubious content and browser notification spam. It is also capable of redirecting visitors to different (likely unreliable/hazardous) sites.

Users primarily access pages like dev-defense[.]com through redirects generated by websites that employ rogue advertising networks. Our researchers discovered dev-defense[.]com while investigating sites that use said networks.

Dev-defense[.]com overview

It is noteworthy that the behavior of rogue sites may vary depending on the visitor's IP address (geolocation). In other words, this information might determine the content encountered on and through such webpages.

When we inspected dev-defense[.]com, it presented us with a questionable article promoting an Android application. After we pressed the "Claim Your Protection Now" button displayed at the end of the article, it prompted a pop-up requesting the browser notification delivery to be enabled.

Once we clicked the "Allow" button for the notifications, dev-defense[.]com displayed another pop-up urging the enablement of these ads – "Missing permissions detected/ Click on the bell icon shown in the top right/left of the address bar then click allow". Afterwards, the page promptly generated a redirect to a site that was down at the time.

Rogue webpages use a variety of deceptive tactics to trick users into permitting their browser notifications. If allowed, the website (e.g., dev-defense[.]com) will spam users with advertisements promoting online scams, untrustworthy/harmful software, and potential malware.

In summary, through pages like dev-defense[.]com – users can experience system infections, severe privacy issues, financial losses, and even identity theft.

Browser notification spam in general

Eukeuktyouex[.]xyzbesteasyclick[.]comdeclinerybelfa[.]buzzcontinue-to-read[.]com, myrrhisunition[.]store, lolydatingcool[.]top, comedyrent[.]com – are merely some examples of rogue websites that we have investigated recently.

Pages of this kind deliver browser notifications that predominantly promote deceptive and malicious content. Keep in mind that while legitimate products or services may be encountered via these ads – they are unlikely to be endorsed in this manner by their developers or other official parties. It is most probable that this promotion is undertaken by scammers who abuse the content's affiliate programs in order to acquire illegitimate commissions.

How did dev-defense[.]com gain permission to deliver spam notifications?

Websites cannot deliver browser notifications without user consent. Therefore, you have likely visited the dev-defense[.]com page at some point and selected "Allow", "Allow Notifications", or a similar option – thus enabling the notification/advertisement delivery.

How to prevent deceptive sites from delivering spam notifications?

To avoid receiving undesirable browser notifications – do not permit suspicious sites to display them (i.e., do not click "Allow", "Allow Notifications", etc.). We advise denying notification delivery (i.e., selecting "Block", "Block Notifications", etc.) or ignoring these requests altogether.

In case of continuous unprompted redirects to questionable webpages, check the device for installed adware. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.

How to avoid browser notification spam?

Internet users should be very skeptical when being asked to allow notifications. While this is a useful feature that allows you to receive timely news from websites you like, deceptive marketers frequently abuse it.

Only allow notifications from websites that you fully trust. For added security - use an anti-malware application with a real-time web browsing monitor to block shady websites that tries to trick you into allowing spam notifications. We recommend using Combo Cleaner Antivirus for Windows.
