ERROR # 0xuaO-0x156m(3) (Activation Warning Alert) Scam In Detail

The ERROR # 0xuaO-0x156m(3) is a dangerous scam that is currently being sent out to criminals worldwide. It is distributed by an unknown hacking group that leverages different tactics to manipulate the users that there is a real problem.

What we know so far is that this scam scheme is currently being distributed by a fake Microsoft Azure platform site that is created and maintained by an unknown hacking group. To a large degree, the success of the infection campaign will largely depend on the marketing of the hacker-controlled site. Methods of spreading it to the prospective targets include the following:

  • Advertising — Links to it may be posted on various hacker-controlled sites and networks. The hackers may also register different domain names to redirect to it. This includes the use of the so-called browser hijackers which are virus-infected plugins made for the most popular web browsers.
  • Carrier Infections — Other malware infections can be the cause of the webpage showing. This is very popular with web-based threats.
  • Online Sites — The criminals may use different types of stolen or fabricated identities to spread the sites. This includes forums, chat rooms, online communities, and etc.

As an Azure website, the hackers will possibly pretend to be Microsoft staff or related companies. Common signs of having fallen to the ERROR # 0xuaO-0x156m(3) scam will be the displaying of intrusive content: they can be pop-ups, text links, banners, and etc. The victims will be manipulated to execute different actions:

  • Call Phone Lines — The victims may be impersonated into calling fake tech support lines and following the instructions of the people who answer.
  • Downloading and Running Software — The pop-ups and other forms of content that are shown to the users may request that the victims run programs from the Internet on their computers.
  • Online Payment — The victims may be shown payment pages that will request fees to be paid to the hackers. This is intentional as the premises of the scam is to make the users think they need to pay to fix the errors.

The main goal of such pages is to make the victims think that there is something wrong with their computers. The pages can emulate the way errors are shown on a computer by creating such pop-ups, banners, and messages. Advanced scripts can be utilized in order to deliberately slow down the computer or produce other types of effects. Such malware can be used to install other types of viruses — these are web-based threats and as such are much more likely to install cryptocurrency miners. These are scripts that are run from within the web browsers and are programmed to download and run performance-intensive tasks. For every completed and reported instance the criminals will receive digital assets directly in their wallets.

Another dangerous action that is run by such malware is the information gathering. This is done by inserting plugins and programs that interact with the system. This can result in the hijacking of personal user’s information and system data. The collected information can be used for crimes such as identity theft. The data that is collected as system-specific information can be used by another module to generate an identifier for each compromised host.

Like other threats of this category, the criminals can edit the hacking sequence and add in other kinds of functionality. For this reason, we recommend that detected instances are removed as soon as possible.
