What to Look for in an Exposure Management Platform (And What Most of Them Get Wrong)

The Hacker News - 29 Duben, 2026 - 13:30
Every security team has a version of the same story. The quarter ends with hundreds of vulnerabilities closed. The dashboards are bursting with green. Then someone in a leadership meeting asks: "So, are we actually safer now?" Crickets. The room goes quiet because an honest answer requires context – which is something that patch counts and CVSS scores were never designed to provide.

Why a recent supply-chain attack singled out security firms Checkmarx and Bitwarden

Ars Technica - 29 Duben, 2026 - 13:00

It has been a bad six weeks for security firm Checkmarx. Over the past 40 days, it has been the victim of at least one supply-chain attack that delivered malware to customers on two separate occasions. Now it has been hit by a ransomware attack from prolific fame-seeking hackers.

The streak of misfortunes started on March 19 with the supply-chain attack of Trivy, a widely used vulnerability scanner. The attackers behind the breach first breached the Trivy GitHub account and then used their access to push malware to Trivy users, one of which was Checkmarx. The pushed malware scoured infected machines for repository tokens, SSH keys, and other credentials.

Both a target and delivery mechanism

Four days later, Checkmarx’s GitHub account was compromised and began pushing malware to the security firm’s users. The company contained and remediated the breach and replaced the malware with the legitimate apps. Or so Checkmarx thought.

Android reminders, reinvented

Computerworld.com [Hacking News] - 29 Duben, 2026 - 11:45

Sometimes, the hardest part about getting stuff done is simply remembering what you have to do — and when.

And ironically, lots of the tools that exist to help us juggle our endless array of incoming tasks only seem to make it even more overwhelming. Truly, it doesn’t take much for the very act of managing your tasks — or maybe even just figuring out the best way to do it — to become a chore in and of itself.

Like many perpetually perplexed plebeians, I’ve exerted far too much energy on the impossible-seeming task of finding a system for tracking tasks that (a) actually works — and (b) doesn’t feel like a burden of its own. I’ve gone through more tasks and reminders systems than any sane person should ever encounter in a lifetime.

And lemme tell ya: At long last, I’ve encountered one that’s the perfect blend of simplicity and power.

It’s a brand new, off-the-beaten-path Android app you probably haven’t heard of but that absolutely should be on your radar. It’s both easier and more effective to use than most of the big-name tasks apps out there right now — and it almost, dare I say, even makes managing your to-dos enjoyable instead of exhausting.

Lemme show ya how it works.

[Keep the knowledge coming with my free Android Intelligence newsletter — three new things to try every Friday and my Android Notification Power-Pack as a special welcome bonus!] 

A new gold standard for Android reminders

My fellow memory-challenged marsupial, allow me to introduce you to the amusingly named Ruff Reminders.

Ruff Reminders is an Android-first creation that’s only been in the Play Store for a matter of hours now —  though I’ve had the opportunity to use it during its development for the past couple of months, as it’s progressed from a, well, rough framework into a polished and well-rounded place for storing all of your tasks both personal and professional and ensuring you never forget anything.

If the Ruff name sounds familiar, by the way, you might be thinking of the similarly themed Ruff Writing app — which puts a simple scrolling scratchpad right on your home screen for on-the-fly thought storing. I’ve featured it as one of my must-have Android widgets for some time now.

Ruff Reminders comes from the same source — an indie Android app developer named Bardi Golriz — and it exists as a perfect companion to its sibling’s scratchpad concept.

So let’s get into it: When you first open up Ruff Reminders, you’re greeted with a simple screen showing you the current day and a prompt to add any new reminders you need into the mix. The idea is that your focus belongs on the here and now — and starting with what you need to do today is the best way to actually get your tasks accomplished.

Ruff Reminders always starts you with a view of your tasks for the current day.

JR Raphael, Foundry

Creating a new task is as easy as tapping the “quick entry” prompt toward the top of the screen and typing. You can also use the plus icon in the lower-right corner of the screen for a more elaborate and detail-oriented task creation mechanism — and that’s where some of Ruff Reminders’ most impressive powers come into play.

To wit: For any task you create, you can schedule yourself a reminder for…

  • A specific date and time
  • A dynamic date or time — as in every Monday, every weekend, the first day of each month, and so on
  • And (drumroll, please…) a specific location — if, say, you want to be reminded about something when you get to the office, when you get home, or maybe even when you walk into a particular store or business
You can set all sorts of different reminders, including ones based on your physical location.

JR Raphael, Foundry

That last one in particular is a true treat to see. Like many Android-appreciating animals, I’ve been irked by Google’s ongoing retirement of location-based reminders all across the platform — first within the old Google Assistant system and then more recently within Google Keep as well. Ruff Reminders handily fills that void while offering a whole lot of other enticing extras that Assistant and Keep never provided.

For instance: For any location-based reminder, Ruff Reminders gives you the option to have a task pop up when you reach whatever location you specify either within a certain specific timeframe or anytime — and to have that reminder exist only once or as a recurring thing, every time you come or go from the location in question.

On that latter point, you can also set the reminder to trigger when you arrive at your chosen location or when you leave it — and you can choose exactly how wide of a radius the app uses to identify the spot — both of which add a whole other layer of flexibility and potential usefulness into the feature.

Ruff Reminders’ location reminders are especially versatile and powerful.

JR Raphael, Foundry

And all of that is still just the start.

Remembering — and beyond

Once you have tasks created, Ruff Reminders really does work to make sure you remember ’em. In addition to setting all of your own preferred reminder patterns for each new task you create, you can tell the app to always nudge you about still-pending tasks for the present day at specific times as well as to keep “chasing” you with more prominent alarms — even multiple alarms, if you want — for items you haven’t finished.

All of those options exist within the dog-shaped Ruff icon in the lower-left corner of the screen:

width="1024" height="919" sizes="auto, (max-width: 1024px) 100vw, 1024px">Ruff’s “nudges” and “chases” add in even more flexibility and reliability with making sure you never forget anything important.

JR Raphael, Foundry

Once you’ve started a task, one tap on its line tells Ruff Reminders that it’s in progress and marks it accordingly. Another tap starts a full-screen timer (for any length you choose) to help you actually focus on the task. And pressing and holding the task marks it as finished.

You can also double-tap to reset an item’s status, if such a need ever arises.

Marking a task as in progress (left) exposes the option to begin a full-screen focus timer (right), if you want.

JR Raphael, Foundry

If something does still manage to slip by without getting completed, it’ll move down to the app’s command bar, at the bottom of the screen — where it shows up inside a red box with the number of unfinished past tasks front and center.

The Ruff Reminders command bar shows you how many missed tasks are still active and pending.

JR Raphael, Foundry

You can always tap that box to revisit and reschedule any missed tasks — or you can find any past task via the app’s swipe-up-from-the-bottom search system. But even more helpful are the ongoing reminders the app will keep bringing front and center whenever you tell it to keep chasing you about any particular item.

Tapping the double up arrows on a missed task moves it right back into your current “today” view.

JR Raphael, Foundry

What else? Let’s see — for any items you set as “ongoing,” Ruff will create a persistent notification so you can easily see what’s lingering on your list. And as you’d expect for any serious Android productivity app, Ruff Reminders has a widget that lets you look at all your tasks for the current day and add new tasks right then and there, on your home screen, without ever having to open anything up.

Between Ruff Reminders’ persistent notification of ongoing tasks and its home screen widget showing today’s tasks, you’ve got no shortage of ways to keep important stuff front and center.

JR Raphael, Foundry

For the true productivity-obsessed power-user nerds among us, Ruff Reminders also has a whole host of step-saving gestures built into its interface. Like all of the app’s more advanced options, you absolutely don’t have to mess with ’em if you don’t want to — but if you’re the type of person who likes learning shortcuts and flying around your phone with taps and swipes, you’ll be delighted by all the possibilities this unlocks. 

The more you use it, the more thoughtful and useful little touches you keep discovering — again, if and only if you want to explore those types of options.

Gestures galore await for the shortcut adorers among us.

JR Raphael, Foundry

What’s most interesting to me about Ruff Reminders is the space it fills between the everything-style, intensive-need to-do apps out there — things like Todoist or even all-purpose productivity tools like Notion, which are great for the right type of purpose and person but can be overwhelming overkill for more casual task tracking — and the super-simple, at times too-limited apps like Google Keep, which are fine for basic info-dumping but lacking in more powerful task management and reminder magic.

Ruff Reminders manages to be both simple and effective — an often overlooked middle-ground for those of us who want to track tasks and remember stuff in a way that goes beyond the most barebones basic approach but that doesn’t require an entire intricate platform to do it.

Oh, and as far as privacy goes, Ruff Reminder’s policy on that front is also refreshingly simple: It doesn’t collect or process any personally identifiable information. Period.

The app doesn’t have ads, either. Instead, it allows you to use its most fundamental setup for free and offers a paid subscription for its full set of features — three bucks a month or $20 per year, at the moment, with the latter price set to bump up to $30 after a while. (That pricing does also vary by country, so the rates will be slightly lower in certain parts of the world.)

For now, all you’ve gotta do is try it out and see if it works as well for you as it has been for me.

And if you need a helping hand to remind you, I know just the app to get the job done.

Who’s the better CEO, Apple’s Tim Cook or Microsoft’s Satya Nadella?

Computerworld.com [Hacking News] - 29 Duben, 2026 - 09:00

Tim Cook’s impending retirement as Apple’s CEO marks the end of an era — the years  when the Apple-versus-Microsoft fight dominated the tech world.

Of course, it’s been a long time since those two companies ruled by themselves. These days, Google, Meta, OpenAI, Anthropic and Amazon are just as influential. Still, Cook’s decision to step down as Apple CEO on Sept. 1 to become chairman of Apple’s board is a good time to revisit the debate: who’s the better leader, Cook or Microsoft CEO Satya Nadella?

Both men faced the unenviable task of replacing larger-than-life company founders and visionaries. Cook took over as CEO at Apple in August 2011, two months before Steve Jobs died. Nadella ascended to the top job at Microsoft in February 2014 after Steve Ballmer stepped down. (Ballmer had replaced founder Bill Gates as CEO in 2000.)

To determine who’s been a better leader — and positioned their companies better for future success — we need to look at the challenges each faced as CEO.

Cook’s and Nadella’s biggest challenges

In the 10 years before Cook took over at Apple, the company saw an unprecedented run of innovation under Jobs, creating products that redefined technology – not only what it could do but also shaping the way people live and work.

The iPod in 2001 launched the digital music revolution. That was followed two years later by iTunes, which completed Apple’s dominance in digital music. The iPhone in 2007 single-handedly created the mobile revolution, along with the follow-on App Store in 2008. That same year, Apple launched the iPad. Then, in May 2011, Jobs unveiled iCloud.

Cook’s two greatest challenges when he took over: make as much money as possible from Jobs’ innovations and continue to create groundbreaking products.

Nadella took over at Microsoft during what has been called the company’s “lost decade.” Quite simply the company had stagnated, launching no new significant products while milking its cash cow, Windows, as much as it could.

In that decade Microsoft couldn’t even handle Windows properly. Windows Vista, launched in 2007, is generally regarded as the worst version of Windows ever. And in  2012, Microsoft released Windows 8, also considered a big miss.

It’s said that, to a man with a hammer, the entire world looks like a nail. The same could be said about Ballmer and Windows: he saw it as the solution to every tech problem that existed. (Gates, by then board chairman, agreed.)

That myopic view led to several disasters, most notably missing out on the mobile phone revolution — even though Microsoft had in 2003 launched Windows Mobile, a smartphone operating system, well before Apple.

Nadella’s greatest challenges were legion: create innovative products, pivot away from Windows, and fix a toxic company culture that had executives spending their energy on turf battles.

How Cook has fared at Apple

By any measure, Cook has been a superb technocratic leader at Apple. His big achievements were in the behind-the-scenes nuts-and-bolts of manufacturing that don’t make headlines, but that helped Apple cash in on Jobs’ many innovations and become a multi-trillion-dollar company.

Most important, he transformed Apple’s supply chain. It was a complicated mess when Cook took over as CEO. He streamlined things by reducing the number of suppliers and manufacturers Apple dealt with. He also put into effect a “just-in-time” delivery of components that the company needed, reducing costs and making the manufacturing process more efficient and more nimble in responding to a fast-changing market.

He also recognized the value of services, transforming iCloud, Apple Music, the App Store, and Apple Pay into financial juggernauts, and rolling out Apple TV+ to critical acclaim. But Cook never succeeded in developing breakthroughs like the iPhone. The Apple Watch has been a hit, but it didn’t change the tech world in the way many of Jobs’ products did. (The jury is still out on the Vision Pro.)

Cook also completely missed out on AI. Apple is so far behind in that area at the moment you can’t even count the company as an also-ran. And that might spell trouble for the future. Making money from aging technologies might not be enough for Apple to remain dominant in the coming years when AI will be king.

Nadella’s tenure at Microsoft

Everyone knew Microsoft was getting a Cook-style technocrat when Nadella became CEO. What surprised everyone — including me — was that it got one of tech’s great visionaries as well.

Nadella took over a moribund company and accomplished one of tech’s greatest turnarounds. He put an end to the company’s divisive culture, de-emphasized the over reliance on Windows, increased its cloud presence, and killed Windows Phone, which had cost the company billions and remained a drag on its success.

Eventually, he reorganized the company to make it cloud-centric rather than Windows-centric, getting rid of a number of problematic executives, including Terry Myerson, who had been executive vice president of its Windows and devices business. Microsoft became a cloud company more than an operating system company.

He also forged a better relationship with customers. Rather than try to ram Windows down their throats at every opportunity, as Gates and Ballmer did, he embraced making Microsoft technology work with competing products. For example, he allowed Linux to run  SQL Server. He also bought the developer platform GitHub, and let it remain open and independent rather than become Microsoft-focused.

Then along came AI. Nadella recognized AI was the future, and by investing in OpenAI, forging relationships with other AI companies including Anthropic, and building an internal powerhouse of AI development, Microsoft became one of the world’s foremost AI companies.

The winner

So who’s been the better CEO? 

Cook took over a company with a wealth of ground-breaking products that had created entirely new markets, and did a great job of milking them for all they were worth. He’s certainly been great at making money for Apple. But he’s leaving behind a company that despite its profitability, faces a problematic future in an AI-first world.

Nadella took over a company whose innovative days were far behind it, rebuilt it from the ground up, killed off money-losing tech like Windows Phone, de-emphasized Windows, and then organized the company around the cloud.

In the last few years, he recognized the potential of AI and has been organizing the company around that. Microsoft is better positioned for the AI future than Apple. 

For those reasons, Nadella comes out on top.
