Last week, Microsoft reported the RCE vulnerability CVE-2021-40444 in the MSHTML browser engine. Kaspersky is aware of targeted attacks using this vulnerability, and our products protect against attacks leveraging it.
This is our latest summary of advanced persistent threat (APT) activity, focusing on significant events that we observed during Q2 2021: attacks against Microsoft Exchange servers, APT29 and APT31 activities, targeting campaigns, etc.
We recently came across unusual APT activity that was detected in high volumes, albeit most likely aimed at a few targets of interest. Further analysis revealed that the actor, which we dubbed LuminousMoth, shows an affinity to the HoneyMyte group, otherwise known as Mustang Panda.
We found new malware samples used in WildPressure campaigns: newer version of the C++ Milum Trojan, a corresponding VBScript variant with the same version number, and a Python script working on both Windows and macOS.
Ferocious Kitten is an APT group that has been targeting Persian-speaking individuals in Iran. Some of the TTPs used by this threat actor are reminiscent of other groups, such as Domestic Kitten and Rampant Kitten. In this report we aim to provide more details on these findings.
