DarkMatter says its Katim phone is secure enough for heads of state, corporations

Ensuring Mobile cybersecurity is no easy task. Protecting against sophisticated hackers, unsophisticated hackers, corporate espionage, organized crime, and state-sponsored attacks is a full-time job. And that’s not to mention the hundreds of cybersecurity threats smartphone users encounter every day. One in five Android users experienced a mobile threat in 2014, according to Kaspersky, and there was a 262 percent increase in the number of iOS vulnerabilities in 2015 compared to 2011. Those who store sensitive information on their smartphone run the risk of data theft … and sometimes worse.

But mobile security firm DarkMatter says it has developed a solution. It’s called Katim, which means “silence” in Arabic, and it’s an end-to-end security platform with ultra-secure encryption, two-factor authentication, and more than half a dozen other security measures designed to deter even the most determined hackers.

“Data is today’s currency,” DarkMatter CEO Faisal Al Bannai said during a press event at Mobile World Congress. “There’s so much that can be accessed through your phone, and data is a treasure mine. Simply by connecting to public Wi-Fi or enabling location tracking on your phone can make you vulnerable.”

The Katim platform is compatible with almost any smartphone running Google’s Android operating system, and DarkMatter has developed its own phone, also called the Katim.

The Katim’s OS-level software comprises a bootloader — the program that loads the phone’s operating system — secured against unauthorized modifications, and a security framework that authenticates every app installed when the phone boots up. It packs secure boot and an encrypted bootloader, as well as two-factor authentication that uses biometric sensors like a fingerprint sensor to ensure the users say who they are. There’s also a hardware switch on the handset’s upper-left-hand side that disables the phone’s cameras and microphones, preventing hackers from gaining access to either.

The Katim also comes preloaded with security-conscious apps. The default messaging app automatically secures photos, images, and files, and encrypts one-to-one voice calls and ephemeral messages that expire after a set amount of time (à la Snapchat). A secure app store features a collection of vetted apps.

Perhaps the Katim’s most impressive function is its remote management. The Katim’s Cyber Command Center, a cloud-hosted management system, allows DarkMatter support staff to remotely disable features like Wi-Fi and cellular, as well as remove malicious apps. In worst-case scenarios, they can even “self-destruct” a Katim phone’s data if they detect tampering.

Hands on: The Katim phone

We had a chance to give the Katim phone a go at DarkMatter’s booth inside the Mobile World Congress convention center.

The Katim boasts a carbon gray aluminum body that’s angled on either side, a little like HTC’s One series of smartphones. It’s a tad hefty at 175g, but not so heavy that it’s uncomfortable to hold one-handed.

It sports a 5.2-inch screen with a Full HD (1,920 x 1,080 pixels) IPS display shielded with a layer of Corning’s Gorilla Glass 5, and a Qualcomm Snapdragon 821 processor paired with 4GB of RAM. The rear camera is a 12-megapixel sensor with phase detection autofocus, an f/1.7 aperture, and dual-color, dual-LED flash. The front camera is a 5MP shooter.

Rounding out the Katim’s accouterments is a fingerprint sensor, a gyroscope and accelerometer, support for Bluetooth 4.2 and Wi-Fi 802.11ac, and 64GB of internal storage expandable via a microSD card reader.

It won’t launch until later this year, but DarkMatter is considering keeping the details under wraps. It’s aiming the Katim at individuals, enterprises, and governments that require the highest levels of security — i.e., heads of states, corporations, and defense departments.

But the company hasn’t ruled out bringing some of the Katim’s software management features to third-party devices.

DarkMatter isn’t exactly the first to market with an encrypted phone. BlackBerry’s new KeyOne features a secured bootloader and an encrypted end-to-end messaging app, and Sikur’s GranitePhone ships with a special set of applications designed with security in mind. But in terms of sheer breadth of security measures, the Katim is one of the most holistic we’ve seen.

It’s too soon to say how well it’ll protect against viruses, social engineering, and everyday cases of malware infection — but DarkMatter seems to have come prepared.

“Our view is to offer cybersecurity end-to-end,” Bannai said. “We think it can only be achieved with a holistic approach. The phone by itself doesn’t solve it.”

The iPhone SE 4 camera specs have leaked. Here’s what we know
The back of the Apple iPhone SE (2022).

Recent reports regarding the upcoming iPhone SE 4 suggest that it will be released in just a few months. Now, we have more news about Apple’s next budget handset.

According to ET News, the iPhone SE 4 is expected to feature a single 48-megapixel rear camera and a 12MP TrueDepth camera on the front. This information comes from a recent supply report from Korea. These upgrades represent a significant improvement over the current iPhone SE 3, which has a 12MP wide camera system and a 7MP front-facing camera. Korea-based LG Innotek has been chosen as the main supplier for both the front and rear camera systems of the upcoming iPhone SE.

Future Samsung phones may steal this great Google Pixel feature

A lot has been said about the impressive capabilities of our phone cameras when it comes to capturing photos. However, they are also quite effective at recording videos. Unfortunately, unwanted background noise can often be captured when filming.

The Audio Magic Eraser is a valuable feature that leverages artificial intelligence to eliminate unwanted noise from recorded videos. While this tool is currently exclusive to Google Pixel 8 and later models, such as the Google Pixel 9 Pro XL, it now looks like a similar tool could be coming to Samsung devices.

It looks like the iPhone 18 may get a significant price increase

The iPhone 18 is expected to launch in late 2026, but details are already emerging thanks to a series of leaks. Unfortunately, some of those details are less than pleasant  — like the possibility of a significant price hike due to a few of the planned upgrades.

Well-known tipster Jukanlosreve shared a post on X that stated that plans for Apple's 2nm A20 chip are finalized, but that the cost of each processor is expected to jump from $50 to around $85. That's a price increase of 70%, and while Apple may choose to eat the increased costs, it's more likely they will trickle down to the consumer.
