A mysterious hacking group has compromised the server infrastructure of a popular Android emulator and has delivered malware to a handful of victims across Asia in a highly-targeted supply chain attack.<\/p>\n

The attack was discovered by Slovak security firm ESET on January 25, last week, and targeted BigNox<\/a>, a company that makes NoxPlayer, a software client for emulating Android apps on Windows or macOS desktops.<\/p>\n

ESET says that based on evidence its researchers gathered, a threat actor compromised one of the company’s official API (api.bignox.com<\/em>) and file-hosting servers (res06.bignox.com<\/em>).<\/p>\n

Using this access, hackers tampered with the download URL of NoxPlayer updates in the API server in order to deliver malware to NoxPlayer users.<\/p>\n

“Three different malware families were spotted being distributed from tailored malicious updates toselected victims, with no sign of leveraging any financial gain, but rather surveillance-related capabilities,” ESET said in a report<\/a> shared today with ZDNet<\/em>.<\/p>\n

Despite evidence implying that attackers had access to BigNox servers since at least September 2020, ESET said the threat actor didn’t target all of the company’s users but instead focused on specific machines, suggesting this was a highly-targeted attack looking to infect only a certain class of users.<\/p>\n

Until today, and based on its own telemetry, ESET said it spotted malware-laced NoxPlayer updates being delivered to only five victims, located in Taiwan, Hong Kong, and Sri Lanka.<\/p>\n
