’9939110.info’ Pop-Ups

Posted: November 17, 2015

The '9939110.info' pop-ups are phishing attacks meant to expose computer users to technical support hoaxes. Such tactics may be initial phases in attacks for collecting your information, installing threats or opening remote access to your computer. Security information delivered through the '9939110.info' pop-ups can be assumed to be completely inaccurate, and you should block recurring attacks from this domain with appropriate anti-malware software and strategies.

Why not to Call the Phone Number in Your Browser

Threat authors may design their campaigns with an emphasis on speed, registering new domains, launching attacks, and then abandoning them before information about the new threats can circulate widely. In November, malware experts saw one example of such a rapid campaign emerging from the 9939110.info website, using the '9939110.info' pop-ups to imitate online security warnings. The domain's owner took steps to protect his identity with a proxy service, and, for now, only one other, major PC security brand can confirm the site as being hostile.

The '9939110.info' pop-ups use embedded scripts to imitate pop-up alerts that warn computer users of a range of different security issues, regardless of any real or nonexistent security problems with the PC loading the Web page. Some of these fake issues may include:

  • Disabled Windows services, such as the Windows Firewall.
  • The presence of Trojans, viruses or other types of threatening software.
  • 'Suspicious' activity monitoring your Web history and network data.
  • Suspended Web accounts.
  • Missing Windows .NET Framework files.

However, the '9939110.info' pop-ups are incapable of identifying any of the above problems in PCs that are suffering from them. Their actual purpose is to redirect any readers to a fake technical support numberCon artists may use the following conversation to sell fake software, ask you to modify your computer (often to allow backdoor access to it) or gain access to your financial information.

Pulling Your Browsers out of the '9939110.info' Pop-Ups Problems

The '9939110.info' pop-ups sometimes may be associated with some of the symptoms they describe, but only incidentally, as a result of further attacks by previously installed threats. Such threats may include browser-hijacking attacks, which malware experts often see implemented through changes to your desktop shortcuts, Hosts file settings or local Internet settings. Most PC users should try to reverse these changes with the same anti-malware scanning technology that also can remove the threat causing these attacks. The '9939110.info' pop-ups don't tie themselves to any single brand of browser, and may implement themselves universally, throughout multiple Web-browsing applications.

Although one PC security company has identified content related to potential threat distribution on their domain, the '9939110.info' pop-ups have yet to be confirmed distributors of threatening software. However, blocking scripts and monitoring your browser settings for security purposes are always recommended by malware experts, particularly when exposing your computer to hostile websites. Attacks capable of implementing themselves through the '9939110.info' pop-ups are likely to take advantage of vulnerabilities that will not demand any interaction with their content, to cause infections.
