Patch-free Tuesday

Usually we submit a blog entry to our readers reminding them the second Tuesday of each month is Microsoft’s ‘Patch Tuesday’. As it stands however, Microsoft will not be releasing any patches today.

Whether or not the lack of updates relates to the ealier-than-usual changeover to Daylight Savings Time changeover is anybody’s best guess. Whatever the case may be, please enjoy your Patch Free Tuesday!

Ferocious Kitten: 6 years of covert surveillance in Iran

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.

Andariel evolves to target South Korea with ransomware

Operation TunnelSnake

A newly discovered rootkit that we dub ‘Moriya’ is used by an unknown actor to deploy passive backdoors on public facing servers, facilitating the creation of a covert C&C communication channel through which they can be silently controlled. The victims are located in Africa, South and South-East Asia.
