Botnet


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. [Read More]

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... [Read More]

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. [Read More]

Digital Video Recorders / Network Video Recorders (DVR/NVR) Back in 2015, our telemetry detected a relatively small number of IPS signature hits on known vulnerabilities targeting DVR/NVR devices (~ 749 hits). In 2016, however, we saw this number increase alarmingly to around 1.5 million hits. By using a size comparison chart again, we can see the huge increase more clearly when we compare both years, as shown below: The question, of course, is what contributed to this huge increase in detected hits? Once again, let’s look at the... [Read More]

Attacks targeting and originating from IoT devices began grabbing news headlines toward the last quarter of 2016. Insecure IoT devices became the low-hanging fruit for threat actors to easily exploit. Some were even notoriously used as botnets to launch DDoS attacks against selected targets. For example, the infamous Mirai botnet exploited weak login vulnerabilities in insecure IoT devices such as IP cameras and home routers, and was responsible for one of the largest known DDoS attacks to date. Besides being used in DDoS attacks, exploited IoT... [Read More]

Dot ransomware is a new Ransomware-as-a-service(RaaS) that is openly available in hacking forums. And following the current trend in malware services, it uses web portals hosted in the TOR network for anonymity. Commission-based Profit While lurking in hacking forums, we came across a post for this new ransomware service. RaaS services are now switching from a one-time fee or subscription payment model to a commission based strategy. One advantage of this scheme is that the up front price for the ransomware is free, and any profits realized... [Read More]

Introduction Dyzap belongs to a family of malware designed to steal confidential information from enormous target applications by installing a “man in the browser” attack into common browsers. FortiGuard Researchers recently discovered a new variant of this Trojan virus. Stolen information may include, but is not limited to, system information and application credentials stored on infected systems. In this blog, we will explain how the malware steals user accounts, acts as a keylogger, and communicates with its C&C server. Stealing... [Read More]

  One month ago we captured a Word document infected with malicious VBA code, which was detected as WM/Agent!tr by the Fortinet AntiVirus service. Its file name is InternalFax.doc, and its MD5 is 4F2139E3961202B1DFEAE288AED5CB8F.  By our analysis, the Word document was used to download and spread the botnet TrickBot. TrickBot aims at stealing online banking information from browsers when victims are visiting online banks. The targeted banks are from Australia, New Zealand, Germany, United Kingdom, Canada, United States, Israel, and... [Read More]
