World Environment Day – Giant vacuums are sucking CO2 out of the air

Today is World Environment Day and we should focus on reimagining, recreating and restoring Earth’s climate. Climate change is our time’s biggest environmental emergency. Could part of the solution be vacuuming carbon dioxide (CO2) out of the air? One company – started by university friends who saw glaciers recede before their eyes – is doing just that.

Operating some 14 plants worldwide, Climeworks are combatting the climate crisis with giant vacuum cleaner-like units that capture CO2. They offer CO2 removal as a service, helping people and companies ‘sequester,’ or store, their emissions in products like stone and even carbonated drinks. In the video, the Climeworks team share their passion and plans to transform the future of the planet.

For more, check out Climeworks’ Project Developer Nino Berta’s interview with Kaspersky Secure Futures.

Take part in an interactive cyber bank heist

Put on your balaclava and gloves, and tell your partner you’ll be busy for an hour. You’re about to step inside history’s biggest cyber bank heist.

Go behind the scenes of the biggest cyber heist in history

The Carbanak cybergang once hacked an ATM and forced it to spit all its money out. Instead of trying to physically break into cash machines, Carbanak found a more elegant, stealthy approach.

They hacked into bank networks, learned how the machines worked, then triggered them to spill all the money. They’d swoop past and pick it all up – until they got caught.

Why are we telling you about cash machine attacks?

The new interactive version of our film about the Carbanak ATM attacks, Cashing In, lets you take part in a cyber bank heist. What would you change if you were the plan’s mastermind? Tell us your ideas on Twitter and Facebook.

Why is ransomware now life threatening?

When a patient died after a ransomware attack meant she had to be diverted from her nearest center for care, the cybersecurity world paid close attention. Why is this event being described as a warning for the future of cyber defense? Watch Ransomware: An Escalating Threat to find out.

Ransomware’s malicious history

In 1989, a Harvard Ph.D graduate sent 20,000 floppy disks to that year’s international AIDS conference attendees, labeled AIDS Information – Introductory Diskettes. They were loaded with the earliest known ransomware, PS Cyborg. It encrypted files on the host’s computer unless the owner sent $189 to PC Cyborg Cor. And it was no misguided academic experiment – the graduate just wanted extra cash.

Malwaer changes focus

Fast forward 31 years from ransomware’s inception. Today, this form of malware is life threatening.

Historically, ransomware targeted personal computer users. Today, the profit’s in attacking businesses, because they have more money and valuable data. By the end of 2021 there will be a ransomware attack every 11 seconds, causing overall damage worth 20 billion US dollars. But it’s not just about money.

Tragic incident heralds a new age of secuity concern

The coronavirus pandemic was the opportunity of the decade for ransomware. While overrun healthcare systems experienced an unprecedented wave of attacks, one ransomware incident in Dusseldorf, Germany stood out.

Medics received a call from a woman in pain. When they saw her, they realized she needed urgent surgery. They planned to take her to the local university hospital, but a ransomware attack had shut down its crucial machinery, so she had to be diverted to another emergency unit. She died on route.

With the consequences of ransomware now proven deadly, how do we protect ourselves, our loved ones and our businesses? Prepare yourself with free ransom decryption tools from No More Ransom – an initiative by the Netherlands’ police, Europol’s European Cybercrime Centre, Kaspersky and McAfee.

Down with Doxing: What to do to stop it

Doxing. Have you heard of it? If not, here’s why you might want to get up to date and some simple tips to keep protected. Essential personal data protection reading.

Open access to data – friend or foe?

The accessibility of information today is one of our most empowering freedoms. But it can also fuel malicious personal attacks, known as doxing or doxxing. We’re about to take you through what doxing is, how criminals do it and how to prevent it.

What is doxing?

Doxing is maliciously revealing personal information online, for example, posting an anonymous blogger’s real name or address. Doxers aim to punish, intimidate or humiliate their target by finding out sensitive information and using it against them, like selling your credit card details or threatening to burgle your home.

The never-ending black hole of personal information that is the internet means anyone with the time, motivation and interest can weaponize your personal data. And doxing is a growing problem.

How does doxing work?

These are the most common ways doxers grab data to expose someone.

Tracking usernames

When someone uses one username across multiple platforms, doxers can follow the trail.


Phishing scams are fake emails luring victims to click through to a malicious site where attackers may steal sensitive information.

Stalking social media

Geotagging your photos? Sharing your work location? Doxers can use this to build up a picture of your life and even to deduce the answers to your account security questions.

Is doxing that bad?

Yes. Doxing can have catastrophic consequences.

In 2015, hackers forced entry to dating site for people in committed relationships, Ashley Madison, stealing 32 million users’ data. They demanded payment to return the records but didn’t get it, so published all the data online, causing professional and personal harm, and probably a divorce or two. And then in 2020 Ashley Madison’s attackers came back for more.

Doxing knows no bounds. There are no clear good or bad sides. After an anonymous UK-based security researcher saved the world from a powerful cyberattack, the media outed his real identity and address, leaving him open to a revenge attack from the cybercrime group he went out to stop. Marcus Hutchins’ story is one of a kind.

Protect yourself from doxers with this checklist

Recent research shows more of our data is being sold to organizations and criminals. Cybercriminals could use almost all of it for doxing or cyberbullying.

Credit cards and banking log-ins are the most in-demand. They’re used for extortion, phishing schemes and straight-up money theft. Meanwhile, doxxers use personal account access to cause reputational harm. How do you stop it happening to you? This anti-doxing checklist has everything you need to stay safe.

Keen to learn more about doxing and how to prevent it?

Kaspersky, in collaboration with, has just released a free doxing training course. You’ll learn about the dangers of dox attacks, how to protect against them and what to do if you’re a victim.

These outstanding sci-fi films didn't make The Oscars

Invisible men, brutal algorithm-driven dystopia and devices that fragment consciousness – it’s been a tasty year for sci-fi. As we approach The Oscar’s 2021, we look at a few movies about the future of tech that, unfortunately, didn’t make the shortlist. Which one surprises you the most?

How did these sci-fi films miss out on The Oscars 2021?

It’s that time of the year again. The great and good from the world of film come together to celebrate cinematographic achievements. Except, this year, we won’t be focusing on those. We’ll be focusing on those that *didn’t* make it.

Yes, we’re delving into the depths of the unrecognized to focus on what we do best: tech film. The future of technology to be precise. There’s a rich well to drink from, too. So here’s our favorite sci-fi films about the future of tech that *didn’t* make the list for The Oscars 2021.

The Invisible Man (above)

Director: Leigh Wannel

Griffin, a scientist interested in optics, stalks his wife with an invisibility suit which only works when he’s totally naked. The suit supposedly bends light, using various cameras and displays to record the wearer’s surroundings and transmit them on its surface. You might be thinking, can someone actually make an invisibility suit? It may be closer than we think.

Watch it: YouTube, Amazon Prime


Director: David S.F. Wilson

Vin Diesel is back. After witnessing his wife’s murder, his character Ray wakes up in a strange facility with amnesia. Turns out his blood has been replaced with nanorobots that give him superpowers – think Wolverine meets The Punisher. He can heal from any injury thanks to the tiny helpers in his blood, plus morph his own body, changing his shape and appearance. Sound like your kind of thing?

Watch it: YouTube, Amazon Prime, Google Play


Director: Brandon Cronenburg

Will the life of an assassin ever get any easier? Possessor thinks so. In this near future tale, hired killers, called ‘possessors,’ control the bodies of others to earn their money. No trace, no trouble. But how does it work? Brain-implant technology that plants the consciousness of one into the other. Thing is, both exist in the same body. Surely that’s a recipe for disaster? Yes, as our protagonist finds out.

Watch: YouTube, Amazon Prime, Google Play

Black Box

Director: Emmanuel Osei-Kuffour Jr.

Widowed protagonist, severe amnesia and a new form of experimental brain treatment – what could go wrong? Nolan is struggling to adapt to life after the loss of his wife, so he turns to tech to sort himself out. In Black Box, tech — in this case, a virtual reality headset — is used to help access and unlock memories, drastically altering our personalities and perspectives on our past. The hope? That by uncovering the dark recesses of our brain through VR reconstructions, we can come to terms with grief, pain and anguish. Keen to give it a try?

Watch it: Amazon Prime

Minor Premise

Director: Eric Schultz

R10 – recognize the name? Probably not; it’s a fictional, mind-altering device. Ethan, our protagonist, built R10 – which isolates sections of the brain that control emotions or behaviour, allowing us to better understand our personalities. But things go a little bit stray when Ethan’s consciousness starts fragmenting into different pieces. It’s not a technology we see getting past regulators any time soon. That said, would you try it?

Watch it: Amazon Prime

Ready to stream? Make sure you do this first

If you’re streaming films, particularly recently released ones, do it from a recognized, paid service. Why? Because free streaming sites are a breeding ground for phishing attacks, spam emails and malware. Kaspersky experts found that almost 70 percent of malicious files are disguised in three Oscar-nominated movies: Promising Young Woman, Judas and the Black Messiah, and the Trial of the Chicago 7.

In short, cybercriminals know that ‘free’ films are a popular lure for unsuspecting victims. So how can you avoid getting hacked? Check the website’s authenticity (including URL spelling), pay attention to files you’re downloading (a video file will never be called .exe or .msi) and use reliable security solutions. There, you’re ready to stream.
