The following detections were updated this past week with changes to kill chain phase(s) or MITRE ATT&CK tactic(s)/technique(s):
The APT-C-23 group is known to have used both Windows and Android components in its operations, with the Android components first described in 2017. In the same year, multiple analyses of APT-C-23’s mobile malware were published. ESET

Some organizations track North Korean clusters or groups such as Bluenoroff, APT37, and APT38 separately, while other organizations may track some activity associated with those group names by the name Lazarus Group. MITRE
Cobalt Strike is a commercial, full-featured, penetration testing tool which bills itself as “adversary simulation software designed to execute targeted attacks and emulate the post-exploitation actions of advanced threat actors”. Cobalt Strike’s interactive post-exploit capabilities cover the full range of ATT&CK tactics, all executed within a single, integrated system.
In addition to its own capabilities, Cobalt Strike leverages the capabilities of other well-known tools such as Metasploit and Mimikatz. MITRE

Microsoft successfully detected and disabled attack activity abusing OneDrive by a previously undocumented Lebanon-based activity group Microsoft Threat Intelligence Center (MSTIC) tracks as POLONIUM. The associated indicators and tactics were used by the OneDrive team to improve detection of attack activity and disable offending actor accounts. To further address this abuse, Microsoft has suspended more than 20 malicious OneDrive applications created by POLONIUM actors, notified affected organizations, and deployed a series of security intelligence updates that will quarantine tools developed by POLONIUM operators. Microsoft

A Trojan downloader is a type of Trojan horse that downloads and installs files, often malicious programs. A Trojan horse is a type of software that looks legitimate but can be malicious in nature. Sometimes these programs can be downloaded onto a device without the user’s knowledge or consent.

A dropper is a kind of Trojan that has been designed to "install" some sort of malware (virus, backdoor, etc.) to a target system. The malware code can be contained within the dropper (single-stage) in such a way as to avoid detection by virus scanners or the dropper may download the malware to the target machine once activated (two stage).
