The popularity of online shopping has been growing during the past few years, a trend accelerated by the pandemic.

This campaign was first identified at the end of 2021, with the attackers impersonating the legitimate cleaning service Maid4u.

It is still ongoing as of the publication of this blogpost, with even more distribution domains registered after its discovery. In January 2022, MalwareHunterTeam shared three more malicious websites and Android trojans attributed to this campaign.
On top of that, ESET researchers found four more fake websites. All seven websites impersonated services that are only available in Malaysia: six of them, Grabmaid, Maria’s Cleaning, Maid4u, YourMaid, Maideasy and MaidACall, offer cleaning services, and the seventh is a pet store named PetsMore…
