Garmin may finally catch up with this key Apple Watch heart health feature

Garmin is heavily rumored to be working on its own version of an electrocardiogram sensor, a device that could help to improve its heart health metrics by identifying irregular heart rate rhythms.

ECG sensors don’t measure your blood flow; instead, they detect signs of atrial fibrilation, or AFib, which is a cause of strokes and heart issues, and can alert you if it picks up indicators of the condition. 

None of the smartwatches that have ECG sensors are 'medical grade' or certified for use in a clinical setting – not even the best Apple Watch or the best Fitbit – but ECG readings can provide a useful indication that you should get yourself checked out by a medical professional. Considering how advanced Garmin is in the smartwatch space, it’s interesting that it’s taken the company so long to get here, and that it hasn't considered the feature a priority in the same way as its competitors. 

According to The5KRunner, which has a good track record of predicting future Garmin features, a reliable source has indicated that the feature is coming with a new series of Forerunner watches, the 265 and 965. Spotted by our colleagues at Advnture, the leak reveals that you’ll be able to place two fingers on the metal bezel in front of the watch, and it will create a circuit with the metal sensor that sits on your wrist. The Apple Watch uses the digital crown to achieve the same result. 

ECG is available on the Fitbit Sense 2 and Fitbit Charge 5, and has been available on the Apple Watch since the Series 4. So why has it taken so long for Garmin to bring the feature to its watches?

Garmin’s website informs us that newer watches can identify “abnormal” heart rate spikes after a workout. It says “if you are inactive for 10 minutes or more, and your heart rate stays above your set threshold, you’ll get an alert on the watch. This setting is found under the Heart Rate settings typically accessed from the Heart Rate widget on the watch”. However, this is different than a true ECG app, which can look for irregularities in your heart rate on command, not just immediately following a workout.

A bit of boxed text on the same page also stresses that “Garmin watches are not medical devices. The heart rate monitor data is not intended to be used for medical purposes, nor is it intended to diagnose, treat, cure, or prevent any disease or condition.” That said, ECG apps aren’t authorized for use in clinical settings either, and are only supposed to provide an indication that something could be awry. 

The simplest answer is that Garmin has never needed ECGs to sell itself, concerning itself only with the accuracy of its heart rate sensor during workouts and sleep tracking. Garmin watch wearers, who often look for specialist devices, are probably less likely to be concerned with having an ECG sensor than 'lifestyle' watch fans who wear the Sense 2 or Apple Watch, both do-it-all health devices.

However, expect Garmin to announce its ECG debut with a bit of ceremony when (if?) the first ECG-capable watch arrives later this year.

Code-generating tools could be more of a security hindrance than help

New research by a group of Stanford-affiliated researchers has uncovered that code-generating AI tools such as Github Copilot can present more security risks than many users may realize. The study looked specifically at Codex, a product of OpenAI, of which Elon Musk is among the co-founders.  Codex powers the Microsoft-owned GitHub Copilot platform, which is designed to make coding easier and more accessible by translating natural language into code and suggesting changes based on contextual evidence. AI-coding problems Lead co-author of the study, Neil Perry, explains that “code-generating systems are currently not a replacement for human developers”. The study asked 47 developers of differing abilities to use Codex for security-related problems, using Python, JavaScript and C programming languages. It concluded that the participants who relied on Codex were more likely to write insecure code compared with a control group. Read more > These are the best laptops for progr

Port of Lisbon hit by ransomware attack

One of Europe’s busiest seaports, the Port of Lisbon, has been hit with a ransomware attack that knocked some of its digital systems offline. "All safety protocols and response measures provided for this type of occurrence were quickly activated, the situation being monitored by the National Cybersecurity Center and the Judicial Police," a statement shared by the Port of Lisbon Administration (APL) with local media earlier this week said. The incident failed to impact the port’s operations, but did take its official website,, offline. LockBit taking responsibility "The Port of Lisbon Administration is working permanently and closely with all competent entities in order to guarantee the security of the systems and respective data," the statement concludes. While the company doesn’t explicitly say it was targeted with ransomware, the LockBit ransomware operator has added APL to its leaks website, taking responsibility for the hit.  The databas

This new Linux malware floods machines with cryptominers and DDoS bots

Cybersecurity researchers have spotted a new Linux malware downloader that targets poorly defended Linux servers with cryptocurrency miners and DDoS IRC bots. Researchers from ASEC discovered the attack after the Shell Script Compiler (SHC) used to create the downloader was uploaded to VirusTotal. Apparently, Korean users were the ones uploading the SHC, and it’s Korean users who are targets, as well. Further analysis has shown that the threat actors are going after poorly defended Linux servers, brute-forcing their way into administrator accounts over SSH.  Mining Monero Once they make their way in, they’ll either install a cryptocurrency miner, or a DDoS IRC bot. The miner being deployed is XMRig, arguably the most popular cryptocurrency miner among hackers. It uses the computing power of a victim's endpoints to generate Monero, a privacy-oriented cryptocurrency whose transactions are seemingly impossible to track, and whose users are allegedly impossible to identify.

Twitter has hidden the chronological feed on iOS again – and I'm furious

In a controversial move, Twitter has brought back a feature that removes the 'Latest Tweets' view for users on iOS, which is something that many users, including me, hated back in March 2022 – and it's now rolling out. The first time the company decided to do this, 'Home' would appear first in a tab at the top, and there was no way of changing it so that 'Latest Tweets' would be the default view. It was reverted back after the company said it was a 'bug' for iOS users. This time though, it's no bug. Instead, it's 'For You' and 'Following' where you can only swipe between them now, which doesn't make much sense for a platform where you're using the platform to keep up to date with who you follow. It's a bizarre change that makes me ask – who wants this, especially during a time when its new owner, Elon Musk, is bringing in and reversing changes almost every week still? This one change will have big consequenc
