This free download manager site actually just redirected Linux users to malware for years

An infostealing malware campaign has been underway for at least three years, going completely unnoticed, Russian cybersecurity firm Kaspersky has revealed.

The finding came after the company decided to take a closer look at the growing number of Linux-based attacks, which “can operate for years without being noticed by the cybersecurity community.”

This example in particular focuses on what appears to be a free download manager destined for use on Debian machines, which has been available in its malicious form since January 2020.

Affected versions of the downloadable software contain an infected postinst script that is executed upon installation, which the analysts say contains comments in both Russian and Ukrainian.

Having downloaded and installed an infected version of the software for further investigation, Kaspersky’s workers reveal that a Bash stealer is deployed to collect information such as system information, browsing history, saved passwords, cryptocurrency wallet files, and credentials for cloud services - specifically, AWS, Google Cloud, Oracle Cloud Infrastructure, Azure.

Fortunately, the researchers also revealed how the malicious version of the software had been distributed. They confirmed that the official website and its content had not been compromised, and actually, the infostealing version had been posted to online communities like Reddit and StackOverflow over a period of around two years.

The genuine makers of Free Download Manager have since been notified by Kaspersky, though at the time of writing, they had not responded.

According to Kaspersky, the threat actor targeted Linux machines specifically because they are much less frequently analyzed compared with Windows and macOS devices, simply due to popularity reasons. 

Still, there are some very easy steps that users can take to protect themselves online. Most importantly, users should only download from legitimate sources and check things like domains and email addresses against what has been verified as legitimate. Doing so would have saved victims from this case of malware.

The latest Apple TV 4K test lets you watch four sports streams at once

Apple is trying something new with the latest beta version of tvOS 16.5: the option to watch up to four simultaneous streams at once. Right now it's limited to live sports streamed through the Apple TV app on the Apple TV 4K , specifically MLB Friday Night Baseball and the MLS Season Pass. A multi-view option was spotted in the tvOS software last month, but the code was hidden and not enabled. MacRumors reported that the feature would be enabled this weekend, and beta testers have since been able to use it. As yet multi-view hasn't been officially announced by Apple, but it's expected that tvOS 16.5 is going to be pushed out in its final form within the next month or so. WWDC 2023 is around the corner as well, when we should be hearing about the next major updates for Apple's various operating systems – including tvOS 17. How it works Over at 9to5Mac there's a hands-on demonstrating how the multi-view feature works, and it's pretty much as you would expe...

TechRadar's Year in Review: AI revolution, smartphone evolution, and visions of the future

If I had to sum up 2023 in one word it would be AI. Okay, technically that’s two initials, but let’s not quibble – because there’s no doubt that it provided the year in tech with its main story arc. Artificial intelligence was everywhere this year, as every company in the world gawped at the massive impact of ChatGPT, and decided they wanted to jump aboard that bandwagon. You could barely move for new chatbots, new image generators, and new AI-enhanced features in every device released in 2023. And there’s no sign of that changing in 2024; in fact, we expect it to be an even bigger deal. Elsewhere, phones and laptops did much the same as they had the previous year – well, except where they had new AI-enhanced features – so it was in the virtual reality space where bigger changes were afoot. If the Meta Quest 3 was impressive then the Apple Vision Pro looks to be genuinely game-changing, and we can’t wait to see what impact it has in the next 12 months. Of course we also saw plenty ...

Garmin's new radar-equipped tail light will keep you safe on your e-bike

Garmin's Varia bike radars are some of the most popular pieces of cycling tech around – and now the company has delivered its first rearview radar to have been specially designed for some of the best e-Bikes .   Garmin's Varia range mounts to the back of your bike and broadcasts a radar signal behind you, so you can get visual and audible alerts when something's overtaking you. Even better, the new Varia eRTL615 plugs directly into most e-bikes, with no battery required. Because the catchily-named Varia eRTL615 is also a tail light, it'll also make sure you're visible to other vehicles too, promising to emit a flashing or solid light that's visible from up to a mile away in daylight.

You can buy power cables compatible with Bosch, Shimano, or USB-A terminals or connections, with more info on those available on Garmin...
