we found a new sample that may be related to the MuddyWater campaign. Like the previous campaigns, these samples again involve a Microsoft Word document embedded with a malicious macro that is capable of executing PowerShell scripts leading to a backdoor payload.

We identified a MacOS backdoor (detected by Trend Micro as OSX_OCEANLOTUS.D) that we believe is the latest version of a threat used by OceanLotus (a.k.a. APT 32, OceanLotus, APT-C-00, SeaLotus, and Cobalt Kitty). OceanLotus was responsible for launching targeted attacks against human rights organizations, media organizations, research institutes, and maritime construction firms. The attackers behind OSX_OCEANLOTUS.D target MacOS computers which have the Perl programming language installed.
The MacOS backdoor was found in a malicious Word document presumably distributed via email. The document bears the filename “2018-PHIẾU GHI DANH THAM DỰ TĨNH HỘI HMDC 2018.doc,” which translates to “2018-REGISTRATION FORM OF HMDC ASSEMBLY 2018.doc.” The document claims to be a registration form for an event with HDMC, an organization in Vietnam that advertises national independence and democracy.Read More

Its operators are believed to be very organized and develop their own cyberespionage tools that they fine-tuned in their recent campaigns. Many of the tools they use now feature new behaviors, including a change in the way they maintain a foothold in the targeted network.Read More
