Many of AlienVault’s findings are biased toward malware families that have named network detections and for polymorphic malware when listing individual samples. The WannaCry ransomware connectivity check domain was halted through sinkholed by MalwareTech. 40% of the most popular malware domains in 2017 were sinkholed-with their online traffic redirected automatically to another destination, in this case to a safe one-effectively nullifying them. AlienVault compiled a list of the most popular malicious domain names, but acknowledged that attackers rarely use a singular domain that makes it too easy for security professionals and law enforcement to wrest control of the domain away from them. Malware Domains are Vulnerable to SinkholingĪs part of their report. The proliferation of freely available hacking tools for the inexperienced and unscrupulous are a rising concern for cybersecurity professionals in 2018. NjRat has been employed by both no-name criminals and high-level political attackers.ĪlienVault observed that many of the most common malware programs are freely available on the black market, often bundled with anti-virus evasion customizations. NjRat malware are simplistic backdoors with a plethora of how-to videos for beginner hackers available on Youtube. Its global popularity stems from the ease of obtaining and using it. Here are the key findings from part 2: Malware Live Colorful, Global LivesĪnalyzing the anonymised security event information from their customers, AlienVault determined that the most popular malware family, NjRat, is particularly prevalent in the Middle East. The solution-seeker will find in this report another piece of the portrait of the ever-changing digital threat landscape. In the interest of collaborating with other vendors and solution providers to improve the field’s efficiency and comprehensiveness, they released part 2 of their findings on malware this week. To change this to a different value, simply alter the interval in /etc/cron.d/bro-otx.Last week, we examined the findings of SIEM vendor AlienVault’s Open Threat Exchange (OTX) platform report on exploits in 2017. Or just run /opt/bro/share/bro/policy/bro-otx/bro-otx.py again.īy default, pulses will be retrieved on an hourly basis. Grep google /nsm/bro/logs/current/notice.logĪfter successful testing, we can remove our addition from /opt/bro/share/bro/policy/bro-otx/otx.dat We should have received a Bro Notice as well, so lets check that as well: Grep google /nsm/bro/logs/current/intel.log Next, we need to check /nsm/bro/logs/current/intel.log for entries in regard to our indicator: Let's see if we can get an intel hit by doing the following: We can check for errors in /nsm/bro/logs/current/reporter.log. Intel::DOMAINTest-Google-IntelTĪs long as our syntax is correct, we should not need to restart Bro. We can test our configuration by adding another piece of intel to the end of /opt/bro/share/bro/policy/bro-otx/otx.dat. Security Onion standalone/sensor (running Bro)Įxternal internet access - to retrieve updated pulses ( )Īfter using the above script, /opt/bro/share/bro/policy/bro-otx will house all necessary files, etc (including otx.dat, the intel file where all pulses will be fed). In order to do begin, we will need to make sure we satisfy a few prerequisites:Īlienvault OTX API key - can be obtained for free at: Please keep in mind we do not officially support use of this script, so installation is at your own risk. We can easily pull in Alienvault OTX pulses into Security Onion and have Bro utilize them for the Intel Framework by leveraging Stephen Hosom's work with Alienvault OTX integration.
