On or around June 27, 2018, personal particulars of almost 1.5 million people was exfiltrated from a SingHealth database in Singapore where information on patients was stored. Multiple pieces and types of malware was used in this attack which took place over almost a year. This is our analysis into one of the RATs that was used.
SectorD02 is a state sponsored threat actor group which mainly targets governments and organizations around the Middle East. In this case, the target of this malware was Turkey, although it has been reported that they also sometimes target countries outside of the Middle East. One characteristic of SectorD02 is their incrementally changing PowerShell backdoor.
We came across two of SectorD02’s such backdoors at the end of 2018, and we analyzed these variants then identified them as the group’s PowerShell malware.

In early January 2019, an email containing malware was distributed to 77 reporters from the Unification Ministry of South Korea. We analysed these malware and identified them as malware used by SectorA05, and we confirm that they have been using a specific C2 server located in Korea for at least 26 months continuously. We decided to group these wave of attacks under what we call “Operation Kitty Phishing”.
This is an analysis of a custom proxy utility tool used by SectorA01 in attacks on financial organizations globally over the years.
