A ransomware Trojan that gets installed on a computer as a module of Trojan.Gapz.1. The Trojan can capture an image from a web camera connected to a computer and display it on the ransomware screen once access to Windows is blocked.
During installation, the Trojan performs the following actions:
Decrypts the configuration file containing information on countries where the malware can operate and payment systems that the Trojan can target.
Generates a unique ID and sends it together with computer-related information to the remote command and control server.
Receives WHIOS information on the infected computer ID.
Compares this data with the country list from the configuration file and locks the computer only if it is located in Canada, Spain, Germany, France, Italy, Portugal, Austria, Switzerland, Great Britain, Australia or the USA.
Sends the command and control server a new request and gets the bot ID as a reply.
Sends another request and downloads from the server several XML files based on which it generates an image and text for the ransomware message.
The malware can target the following payment systems:
To unlock the computer, the Trojan demands that the victim enter a ransom payment transaction code. The entered code is transmitted to the command and control server to be validated.
If the operating system (OS) can be loaded (either normally or in safe mode), download Dr.Web Security Space and run a full scan of your computer and removable media you use. More about Dr.Web Security Space.
If you cannot boot the OS, change the BIOS settings to boot your system from a CD or USB drive. Download the image of the emergency system repair disk Dr.Web® LiveDisk , mount it on a USB drive or burn it to a CD/DVD. After booting up with this media, run a full scan and cure all the detected threats.
If the mobile device is operating normally, download and install Dr.Web for Android. Run a full system scan and follow recommendations to neutralize the detected threats.
If the mobile device has been locked by Android.Locker ransomware (the message on the screen tells you that you have broken some law or demands a set ransom amount; or you will see some other announcement that prevents you from using the handheld normally), do the following:
Load your smartphone or tablet in the safe mode (depending on the operating system version and specifications of the particular mobile device involved, this procedure can be performed in various ways; seek clarification from the user guide that was shipped with the device, or contact its manufacturer);
Once you have activated safe mode, install the Dr.Web for Android onto the infected handheld and run a full scan of the system; follow the steps recommended for neutralizing the threats that have been detected;
