We delve into the protocol security issues that may crop up from a technology perspective. The scarce awareness that we’ve observed around the current state of MQTT and CoAP can enable attackers in achieving their goals, ranging from reconnaissance and lateral movement to remote control and targeted attacks.

MuddyWater is a well-known threat actor group that has been active since 2017. They have regularly targeted various organizations in Middle East and Central Asia, primarily using spear phishing emails with malicious attachments.

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 explored possible strategies attackers can employ when abusing PowerShell Core. These proofs of concept (PoCs) would help in better understanding — and in turn, detecting and preventing — the common routines and behaviors of possible and future threats that attackers might use. The PoCs we developed using PowerShell Core were conducted on Windows, Linux, and mac OSs. Most of the techniques we applied can be seen from previous threats involving PowerShell-based functionalities, such as the fileless KOVTER and POWMET. The scenarios in our PoCs are also based on the PowerShell function they use.

Several apps on Google Play posing as legitimate voice messenger platforms have automated functions such as fake survey pop-ups and fraudulent ad clicks. Observed variants were deployed one by one since October, with its evolution including evasive techniques and its infection behavior divided into several stages, as well as botnet codes possibly indicative of future attacks.
