UPDATED with comment from Xiaomi.

Toss out your Xiaomi and Huawei phones, but keep the OnePlus ones, warns the authorities of Lithuania following the publication of its own study about the security of Chinese-made 5G smartphones.

"Our recommendation is to non buy new Chinese phones, and to get rid of those already purchased as fast as reasonably possible," Lithuanian Deputy Defense Minister Margiris Abukevicius told reporters during the unveiling of the study from Lithuania'south National Cyber Security Center, according to Reuters.

Xiaomi seems to do the bidding of the Chinese government in ways that could threaten users in the West, the report argues, including putting a censorship module in its phones and secretly communicating with Chinese-run servers worldwide. Meanwhile, Huawei'due south lax app-installation process tin get your telephone infected by Android malware.

Every bit for OnePlus, its phones weren't found by the study'southward authors to be doing annihilation nefarious. The researchers were post-obit upward on reports over the by few years that all three brands engaged in mayhap shady behavior.

Neither Xiaomi nor Huawei have carrier partnerships or direct distribution in the Us, although their relatively inexpensive phones are easy to buy from major online retailers. The brands are widely known and used in Europe.

What to do if you lot have a Huawei or Xiaomi phone

Equally with all Android phones, you'll want to install and use some of the best Android antivirus apps while using these devices. The congenital-in Google Play Protect on Xiaomi phones doesn't cut it, and we don't know what kind of built-in protection Huawei phones accept.

You'll likewise desire to avoid using all app stores other than the congenital-in AppGallery on a Huawei phone. Those third-party stores often have corrupted versions of well-known apps that secretly comprise malware.

Regarding Xiaomi, it's a tougher call. The allegations laid out in the Lithuanian government study are pretty suspicious, even if the censorship module seems to be turned off in phones sold in Europe.

Likewise, the secret Xiaomi communications might possibly be explained equally part of normal operations, but the researchers weren't able to determine that because they couldn't crack the encrypted letters. Yous'll have to decide for yourself whether yous desire to continue using a Xiaomi phone.

Xiaomi dormant censorship

The Lithuanian researchers institute that the Xiaomi Mi 10T regularly updated a file chosen "MiAdBlacklistConfig" that held a congenital-in list of virtually 450 taboo Chinese phrases, including "Free Tibet," "Democratic Movement" and "Long live Taiwan'south independence."

All are phrases that the Chinese government doesn't desire its citizens to see. The telephone has congenital-in filters that are supposed to block users from viewing any kind of media associated with those phrases.

The censorship filter was deactivated for phones sold in the European Matrimony, to which Lithuania belongs, but the researchers said it could easily be flipped on remotely by Xiaomi.

"The beingness of such functionality may jeopardize free access to data and limit its accessibility," stated the written report. "This is of import not only for Lithuania, but as well for all countries using Xiaomi devices."

Secret communications

The Xiaomi telephone also secretly communicated with a Chinese-owned server in Singapore when the user signed up to employ Xiaomi'due south cloud functions, which include telephone backups and lost-device location services.

Communication with remote servers is normal during such procedures, but in this example, the Xiaomi phone sent a (somehow) encrypted SMS message to the server without the user'southward knowledge, and deleted the sent bulletin from the telephone'south text-message log immediately subsequently.

"Investigators were unable to read the contents of this encrypted message, so we can't tell you what information the device sent," one of the report's co-authors told The Tape.

The behavior did not happen once the Xiaomi Cloud service was disabled.

"Automatic sending of messages and its concealment by ways of software pose potential threats to the security of the device and personal information," warned the Lithuanian authorities written report. "In this way, without the user'due south knowledge, device data tin be collected and transmitted to remote servers."

The Xiaomi phone also sent what the researchers called "a relatively large amount of information" about phone configuration, apps and processes, as well as user behavior, to Google Analytics and a similar Chinese firm called Sensor Data.

Information technology also sent "statistical data on the activity of certain applications" to servers across the globe run by the Chinese net company Tencent.

Backdoor to malware

The Huawei P40 wasn't institute to be censoring or spying, but did pose a pretty serious security adventure because it regularly reached out to off-route app stores where malicious apps are known to lurk.

Huawei's default app store is Huawei's own AppGallery. But if the user searches for an app that's not in the AppGallery, then the phone will search third-political party app stores, including merely not limited to APKMonk, APKPure and Aptoide.

The user volition be warned that they're being redirected to off-route stores over which Huawei has no control, and must authorize the jump out of the AppGallery. Notwithstanding, the Lithuanian researchers came across three malicious apps through this procedure while using the Huawei P40.

"Such applications can be downloaded and installed by the user on the mobile phone, thereby jeopardizing the security of the device and the data contained in information technology," the study said.

Update: Xiaomi argument

In response to a asking for comment, Xiaomi provided Tom'southward Guide with this statement, in full.

"Xiaomi'southward devices practice not censor communications to or from its users. Xiaomi has never and will never restrict or block whatsoever personal behaviours of our smartphone users, such as searching, calling, web browsing or the use of third-party communication software. Xiaomi fully respects and protects the legal rights of all users. Xiaomi complies with the European Wedlock's General Data Protection Regulation (GDPR)."
