The prolific TA505 cybercriminal group has continued to target users in Asia, particularly South Korea, China and Taiwan, with various malware delievered via phishing emails. The emails contain a macro-embedded Office attachment or a link to download the malicious document. When the attachment is opened, an embedded script leverages legitimate Windows OS processes or living-of-the land binaries (LOLbins) to install the FlawedAmmyy downloader, ServHelper backdoor or Remote Manipulator System remotes access tool (RMS RAT). In recent campaign, TA505 also deploys a new EmailStealer via the Amadey downloader to hijack email accounts or pilfer SMTP credentials from infected hosts.
