In February 2018, several Russian nuclear scientists were arrested for allegedly mining cryptocurrencies using computing resources located at a Russian nuclear warhead facility. Globally, cryptominers are rapidly increasing and spreading for an obvious reason: it’s lucrative.
At FortiGuard Labs we were interested in searching out other malware that leverages Mirai code modules. Interestingly, one of the families that showed up in our search was the Hide ‘N Seek (HNS) bot, which was discovered in January of 2018. HNS is a complex botnet that uses P2P to communicate with peers/other infected devices to receive commands. In this article, I will discuss how the Mirai bot code was used in this HNS bot.
Educational institution networks continue to be a favorite playground for cybercriminals. Because of the age and interests of the majority of educational users, these networks tend to incorporate cutting edge technologies and strategies.
The first Okiru sample appeared around October 2017 ,and FortiGuard Labs created a write up of its development last December, which included worm capabilities and the embedding of two different exploits. As a follow up, we will now share our findings on the latest Okiru variant that targets ARC processors.
FortiGuard Labs has been actively monitoring FALLCHILL and validating all IOCs, whether we discovered them ourselves through one of our millions of sensors deployed around the world, or collected from the hundreds of threat sharing feeds we subscribe to. Our comprehensive threat information-sharing program includes Governments, Certs, and Strategic Partners from around the world.
Today, the billions of online IoT devices present an even more daunting challenge because they generally don't receive the level of control, visibility, and protection that traditional systems receive. Coupled with widespread automation-based attacks, the potential for damage is even greater. Recent developments, outlined below, reveal why it's time to take IoT security seriously.
BlueBorne affects devices supporting Bluetooth. As such, the PoC they demoed does not spread over Bluetooth: it takes control of a given Bluetooth victim. Apparently, the researchers said they locally created a botnet. But that was clearly a local inside test, and we have no details regarding the botnet's payload.
The first day here at Black Hat is over. On the expo floor, a number of vendors are promoting that they now provide critical threat intelligence along with the other technologies they provide. Of course, in general, this is a good thing. The biggest challenge organizations have historically faced has been a lack of visibility into their networks, especially cloud and virtualized environments. The challenge, however, is how are organizations supposed to consume, correlate, and make use of all of this information? Dozens of intelligence feeds from...
This is the second part of FortiGuard Labs’ deep analysis of the new Emotet variant. In the first part of the analysis we demonstrated that by bypassing the server-side Anti-Debug or Anti-Analysis technique we could download three or four modules (.dll files) from the C&C server. In that first blog we only analyzed one module (I named it ‘module2’). In this blog, we’ll review how the other modules work. Here we go.
