A spam campaign we observed in September indicates attackers are angling towards a more sophisticated form of phishing. The campaign uses hijacked email accounts to deliver URSNIF as part of or as a response to an existing email thread.Read More
With the increasing popularity and real-world use of cryptocurrencies and the fact that cybercriminals will always try to exploit something that can make money for them, it shouldn’t come as a surprise that malware targeting Bitcoin ATMs have started appearing in underground markets.Read More
This blog tackles the recently ill-famed VPNFilter malware and if deployed devices are vulnerable to it. VPNFilter is a newly discovered, multi-stage malware (detected by Trend Micro as ELF_VPNFILT.A, ELF_VPNFILT.B, ELF_VPNFILT.C, and ELF_VPNFILT.D) that affects many models of connected devices. Based on our data from June 1 to July 12, plenty of the devices are still using old firmware versions. In fact, 19 known vulnerabilities, not only taken advantage of by VPNFilter but other malware as well, can still be detected in devices up to this day.Read More
Even before the term IoT was coined, we had the routers at the gateway, most of the time publicly exposed on the internet. In the context of the IoT, the router is perhaps the most important device for the whole infrastructure. All traffic goes through it and it allows for the provision of many services, such as Dynamic Host Configuration Protocol (DHCP), Domain Name System (DNS), content filtering, firewalls, and Voice over Internet Protocol (VoIP), to all connected devices, including computers, smartphones, and IP cameras. If an attacker is able to compromise the router, every device connected to it can be affected. And that’s what a hacking group in Brazil just did.Read More
In this blog post, we will discuss how we developed a human-readable machine learning system that is able to determine whether a downloaded file is benign or malicious in nature.
The development of this actionable intelligent system stemmed from the question: How can we make our knowledge about global software download events actionable? More specifically, how can we use such information to do a better job at detecting the threats posed by the large amounts of new malicious software circulating on a daily basis?
In this last installment of this blog series, we will answer such questions and give a summary of what we did with the information we’ve obtained. Our research paper titled Exploring the Long Tail of (Malicious) Software Downloads provides a more comprehensive look into how we’ve gathered and analyzed our software downloads data.Read More
