Researchers at Fidelis Cybersecurity and Exatel found that Maxthon frequently sends zip files to Beijing over HTTP and this contains a terrifying amount of data about users’ browsing habits. The ueipdata.zip file incudes, among other things, details of the sites visited by users, the applications they have installed, and what searches have been performed.
The company behind the browser says that the data is collected as part of its optional User Experience Improvement Program (UEIP) and is completely anonymous. But security experts found that data was collected regardless of whether users opted in or out of the program.
Maxthon has responded to the allegations, saying it takes them “very seriously” and has “fully investigated this matter”.
