It seems to be the season of sophisticated supply-chain attacks.

This one is in the NoxPlayer Android emulator:

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

Using this access, hackers tampered with the download URL of NoxPlayer updates in the API server to deliver malware to NoxPlayer users.

[…]

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.

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.

I don’t know if there are actually more supply-chain attacks occurring right now. More likely is that they’ve been happening for a while, and we have recently become more diligent about looking for them.
