Security masquerading as a critical system update can completely control a victim’s device and steal their data.
The malware was found bundled in an app called “System Update” that had to be installed outside operator’s servers., the app store for Android devices. Once installed by the user, the app hides and stealthily exfiltrates data from the victim’s machine to the
Researchers at mobile security firm Zimperium, which discovered the malicious app, said once the victim, the malware communicates with the operator’s Firebase server to control the device remotely.
The spyware can steal messages, contacts, device details, browser bookmarks and search history, record calls and ambient sound from the microphone, and take photos using the. The malware also tracks the victim’s location, searches for document files, and grabs copied data from the device’s clipboard.
The malware hides from the victim and tries to evadeit consumes by uploading thumbnails to the attacker’s servers rather than the full image. The malware also captures the most up-to-date data, including location and photos.
Zimperium CEO Shridhar Mittal said the malware was likely part of a.
“It’s easily the most sophisticated we’ve seen,” said Mittal. “I think a lot of time and effort was spent. We believe there are other apps like this, and we are trying our very best to find them as as possible.”
Tricking someone into installing a maliciousto compromise a victim’s device. It’s why Android devices warn users not to install . But many older devices don’t run the latest apps, forcing users to rely on older versions of their .
Mittal confirmed that the malicious app was never installed on Google Play. When reached, a Google spokesperson would not comment on the company’s steps to prevent the malware from entering the Android . Google has seen malicious apps slip through its filters before.
In the early days of the, remote access trojans, or RATs, let snoops spy on victims through their webcams. Nowadays, child are often repurposed to spy on a person’s spouse, known as stalkerware or spouse. This kind of malware has far-reaching access to a victim’s device and comes in various forms and names but essentially does the same thing.
don’t know who made the malware or who it’s targeting., TechCrunch reported on the KidsGuard stalkerware — ostensibly a child monitoring app — that used a similar “system update” to infect victims’ devices. But the researchers
“We are seeing an increasing number of RATs on mobile devices. And the level of sophistication seems to be increasing; it seems like the bad actors have realized that mobile devices have just as much information on them and are much less protected than the traditional endpoints,” said Mittal.
