In our research Exposed and Vulnerable Critical Infrastructure: Water and Energy Industries, we not only found exposed industrial control system (ICS) human machine interfaces (HMIs) but also pointed out how these systems were at risk. This risk is corroborated by the active interest in water and energy ICSs shown by different kinds of cybercriminal groups.

We uncovered an operation of a hacking group, which we’re naming “Outlaw” (translation derived from the Romanian word haiduc, the hacking tool the group primarily uses), involving the use of an IRC bot built with the help of Perl Shellbot. The group distributes the bot by exploiting a common command injection vulnerability on internet of things (IoT) devices and Linux servers. Further research indicates that the threat can also affect Windows-based environments and even Android devices.

Energy and water are two of the most central critical infrastructures (CIs). Both sectors have undergone necessary changes to reflect the latest in technology and improve how natural resources are harnessed and distributed. At present, these changes are heading toward more interconnected systems, especially through the integration of industrial internet of things (IIoT) technologies.

Recently, we found a new exploit using port 5555 after detecting two suspicious spikes in activity on July 9-10 and July 15. In this scenario, the activity involves the command line utility called Android Debug Bridge (ADB), a part of the Android SDK that handles communication between devices that also allows developers to run and debug apps on Android devices.

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.
