Insekt RAT, a new trojan Cisco Talos discovered, is Alchimist's beacon implant written in GoLang and has a variety of remote access capabilities that can be instrumented by the Alchimist C2 server.Īlchimist C2 has a web interface written in Simplified Chinese and can generate a configured payload, establish remote sessions, deploy payload to the remote machines, capture screenshots, perform remote shellcode execution and run arbitrary commands.Īmong the remaining tools, Cisco Talos found a Mach-O dropper embedded with an exploit to target a known vulnerability CVE-2021-4034, a privilege escalation issue in polkit's pkexec utility, and a Mach-O bind shell backdoor.

"Alchimist" is a 64-bit Linux executable written in GoLang and packed with assets including resources for the web interface and Insekt RAT payloads compiled for Windows and Linux. " Talos researchers found this C2 on a server that had a file listing active on the root directory along with a set of post-exploitation tools.Ĭisco Talos assesses with moderate-high confidence that this framework is being used in the wild.

The attack framework is designed to target Windows, Linux and Mac machines.
The Alchimist has a web interface in Simplified Chinese with remote administration features.Cisco Talos discovered a new attack framework including a command and control (C2) tool called "Alchimist" and a new malware "Insekt" with remote administration capabilities.Finally, transcript analysis indicated that PGD1, important for the routing of oleic acid to TAG, was reliant on organic carbon availability, resulting in reduced C18:1 fatty acid accumulation in autotrophic cultures. Furthermore, diurnal light enhanced starch synthesis under mixotrophic conditions. Dark periods induced catabolism of both starch and TAG in autotrophic cultures but TAG alone in mixotrophic cultures.
In contrast, autotrophic cultures lacking organic carbon experienced a slower rate of photosynthetic degradation and funnelled the majority of sequestered carbon to starch synthesis. Under mixotrophic conditions, organic carbon uptake is favoured over photosynthesis, transcript abundance of lipid synthesis genes rapidly increase and acetate is funnelled to TAG synthesis. Results indicate that both organic carbon availability and photoperiod regulate the lipid accumulation response of C. In addition, the growth, PSII integrity, chlorophyll content, triacylglycerol (TAG) content, starch content, and fatty acid composition were characterised. To characterise the impact of differing organic carbon availabilities and photoperiod on the response of the model alga Chlamydomonas reinhardtii to nitrogen stress, the expression of key genes involved in the central carbon metabolism were monitored over a time-course of nitrogen deprivation. Despite significant research efforts to understand the mechanisms of algal lipid accumulation, the influence of commercially relevant growth conditions on the lipid metabolism is poorly understood. Microalgae are a promising platform for the production of renewable fuels and oleochemicals.
