An Android telephone sponsored by the US authorities for low-income customers comes preinstalled with malware that may’t be eliminated with out making the machine stop to work, researchers reported on Thursday.

The UMX U686CL is offered by Virgin Cellular’s Assurance Wi-fi program. Assurance Wi-fi is an offshoot of the Lifeline Help program, a Federal Communications Commissions plan that makes free or government-subsidized telephone service obtainable to millions of low-income families. This system is sometimes called the Obama Telephone as a result of it expanded in 2008, when President Barack Obama took workplace. The UMX U686CL runs Android and is out there for $35 to qualifying customers.
Researchers at Malwarebytes said on Thursday that the machine comes with some nasty surprises. Representatives of Dash, the proprietor of Virgin Cellular, in the meantime stated it did not consider the apps had been malicious.
The primary is closely obfuscated malware that may set up adware and different undesirable apps with out the data or permission of the person. Android/Trojan.Dropper.Agent.UMX incorporates hanging similarities to 2 different trojan droppers. For one, it makes use of an identical textual content strings and virtually an identical code. And for an additional, it incorporates an encoded string that, when decoded, incorporates a hidden library named com.android.google.bridge.Liblmp.
As soon as the library is loaded into reminiscence, it installs software program Malwarebytes calls Android/Trojan.HiddenAds. It aggressively shows adverts. Malwarebytes researcher Nathan Collier stated firm customers have reported that the hidden library installs a variant of HiddenAds, however the researchers had been unable to breed that set up, presumably as a result of the library waits some period of time earlier than doing so.
The malware that installs these packages is hidden within the telephone’s settings app. That makes it nearly inconceivable to uninstall, because the telephone cannot function correctly with out it. “Uninstall the Settings app, and also you simply made your self an expensive paper weight,” Collier wrote.
The second disagreeable shock delivered by the UMX U686CL is one thing known as Wi-fi Replace. Whereas it gives a mechanism for downloading and putting in telephone updates, it additionally hundreds a barrage of undesirable apps with out permission. The app is a variant of Adups, an app from a China-based firm by the identical title. In 2016, researchers caught Adups surreptitiously collecting user data on lots of of hundreds of low-cost telephones from BLU.
“From the second you log into the cell machine, Wi-fi Replace begins auto-installing apps,” Collier stated. “To repeat: There isn’t a person consent collected to take action, no buttons to click on to simply accept the installs, it simply installs apps by itself.”
Whereas the entire put in apps Malwarebytes examined had been clear and freed from malware, the presence of a characteristic that mechanically installs apps poses an unacceptable threat, notably since eradicating the characteristic prevents the telephone from receiving updates. Collier’s submit labeled Wi-fi Replace as malware, however Jérôme Segura, Malwarebytes’ head of menace intelligence, instructed me its precise classification is a PUP, or doubtlessly undesirable program, since there is not any proof the apps which might be put in are malicious.
In any occasion, the 2 apps analyzed by Malwarebytes make use of the UMX U686CL a nasty alternative. The truth that it is made obtainable to low-income customers solely worsens the insult. Malwarebytes stated it notified Assurance Wi-fi of its findings and requested why the telephone it sells comes with preinstalled malware. To date, nobody has responded. In an electronic mail, Dash officers stated: “We’re conscious of this challenge and are in contact with the machine producer Unimax to grasp the basis trigger, nonetheless, after our preliminary testing we don’t consider the purposes described within the media are malware.”
It is not exhausting to seek out on-line discussions like this one complaining of annoying displayed adverts and apps mechanically putting in on the machine with out person permission. A similar thread discusses adverts that show on the homescreen even when a browser is not operating.
Over time, preinstalled malware has been discovered on a raft of low-cost Android telephones from quite a lot of suppliers and producers. An incomplete record features a backdoor on hundreds of thousands of BLU devices, a powerful backdoor and rootkit also on BLU devices, and covert downloaders on 26 different phone models from numerous producers.
It appears the value folks usually pay for low-cost telephones is compromised safety and privateness. Whereas many customers could not have the ability to afford them, shopping for telephones from mainstream and well-known suppliers situated exterior of China is more likely to be a more sensible choice.
