How are the Southeast Asian Online Gambling Sites Targeted?
It began when the hackers target a Philippine-based company’s support team via a spear-phishing email. The email is asking the recipients to open a .DOCX file to view the supposedly display error that their customer is having.
Upon opening this file, the document embedded an executable file that installs malware via two previously undisclosed backdoors. Later versions have a backdoor that utilizes the Dropbox file hosting service as its command-and-control channel.
Once compromised, a user’s computer will pillage for passwords, databases, source codes, and other proprietary technical information. Also, it is happening while installing other malware for future operations.
TrendMicro is investigating this incident, and their research suggests links to a Chinese-led group of hackers known as Winntl. Also, they are targeting gambling sites for a decade or more.
