Black marketed Windows banking & POS Trojan Minerva turns in-the-wild

10309990_1418461665091456_1542203837_oThe path from the creation of malicious program to its delivery onto victims’ computers is long nowadays and involves many different players with the same goal – to make a financial gain. Malware authors usually offer their software to cyber criminals who in turn distribute it via underground forums. This is the how they keep their anonymous status. We have previously seen many famous malicious programs start this way.

In the past, the Russian banking Trojan Carberp was heavily advertised on shady forums. In the beginning of the year, an attempt to sell a new ransomware called Prison Locker was reported. Last year, we blogged about Trojan Solarbot which choose to promote itself through a well- designed website, appearing very official.

However, we don’t always know all the details about every piece of malware, from the code to how it is being distributed. The Trojan dubbed i2Ninja, for example, made headlines last year, but we never received a real sample containing all the functionalities the media reported on. Or do you remember the Hand of Thief Trojan for Linux desktops? Its variant for the Android platform was also advertised, but again, we never encountered it in our Virus Lab. These advertisements could have lacked the real code behind them or may have gone under in the pile of cyberthreats.

In March 2013 a new banking Trojan dubbed Minerva was introduced on a Russian forum. We will see that it is awfully successful in what it promised to do. Read more…

Win32/64:Napolar: New Trojan shines on the cyber crime-scene

In recent weeks, malware samples resolved as Win32/64:Napolar from AVAST’s name pools generated a lot of hits within our file and network shields. Independently, we observed an advertising campaign of a new Trojan dubbed Solarbot that started around May 2013. This campaign did not run through shady hacking forums as we are used to, but instead it ran through a website indexed in the main search engines. The website is called http://solarbot.net and presents its offer with a professional looking design:

For the Win32/64:Napolar Trojan, the pipe used to inter-process communication is named \\.\pipe\napSolar. Together with the presence of character strings like “CHROME.DLL,” “OPERA.DLL,” “trusteer,” “data_inject,” and features we’ll mention later, we have almost no doubts that the Trojan and Solarbot coincide. Let us look at some analysis.
