Picture this: a news story detailing a cyberattack in which no data was exfiltrated, thousands (or even millions) of credit card details weren’t stolen, and no data was breached. While this isn’t the type of headline we often see, it recently became a reality in Las Vegas, Nev. On January 7, 2020, news broke that the city of Las Vegas had successfully avoided a cyberattack. While not many details were offered in the city’s public statement, local press reported that the attack did employ an email vector, likely in the form of a direct ransomware attack or phishing attack. The use of the word “devastating” in the public statement led many to believe ransomware was involved. This inference isn’t farfetched—and is likely a correct conclusion—given that cities throughout the U.S. have seen ransomware attacks on critical systems. Attacks that have cost those cities millions of dollars.

For years, we have been told that cyber-attacks happen due to human-errors. Almost every person has stressed about training to prevent cyber-attacks from taking place. We have always been on the alert to dodge errant clicks or online downloads that might infect devices with security threats.
However, not all attacks need a user’s oversight to open the door. Although avoiding clicking on phishing emails is still significant but there is a cyber threat that does not need any human error and has been in the recent news. It is known as Zero-Click attack where some vulnerabilities can be misused by hackers to launch attacks even without interaction from the victim.
Rather than depending on the hardware or software flaws to get access to the victim’s device, zero-click attacks eliminate the human error equation. There is nothing a victim can do once coming into the limelight of the hacker. Also, with the flourishing use of smartphones around the world that entails all the personal information and data, this thread has expanded enormously.
How Zero-Click Attacks Occur?
The core condition for successfully pulling off a zero-click is creating a specially designed piece of data which is then sent to the targeted device over a wireless network connection including mobile internet or wifi. This then hit a scarcely documented vulnerability on the software or hardware level.
The vulnerability majorly affects the messaging or emailing apps. The attacks that have begun from Apple’s mail app on iPhone or iPad, have now moved ahead on Whatsapp and Samsung devices. In iOS 13, the vulnerability allowed zero-click when the mail runs in the background. It enables attackers to read, edit, delete, or leak the email inside the app.
Later these attacks moved to Samsung’s android devices having version 4.4.4 or above. The successful attacks provide similar access to the hackers as an owner, entailing contacts, SMS, and call logs.
In 2019, a breach on Whatsapp used the voice call functionality of the app to ring the victim’s phone. Even if the victim didn’t pick the call and later deleted it, the attacks still installed malicious data packets. These grants access to the hacker to take complete control of call logs, locations, data, camera, and even microphone of the device. Another similar attack had happened due to the frangibility in the chipset of WI-FI that is used in streaming, gaming, smart home devices, and laptops. The zero-click attack blooms on the increase of mobile devices as the number of smartphones have reached above 3 billion.
How To Avoid Zero-Click Attacks?
Most of the attacks of zero-click target certain victims including corporate executives, government officials, and journalists. But anyone using a smartphone is a possible target. These attacks cannot be spotted due to the lack of vulnerabilities. So the users have to keep the operating system along with the third-party software updated. Also, it is a must to give minimal permissions to apps that are being installed on the device.
Moreover, if you own a business and are afraid of the zero-click attacks on your company’s app, you can always seek IT consultations from top-notch companies orhire developersthat will help in developing applications with hard-to-creep-into programming languages where detecting an attack is efficient.

Over the last year, the education delivery model has changed rapidly. Universities have learnt to operate entirely remotely and now that learning may resume in person, a hybrid education model will likely continue. The transition from physical to online models happened so quickly that it left many IT networks exposed to serious harm from outside forces. With a hybrid model, there is likely a widening attack surface area.
A recent spate of attacks suggests that cyber-criminals are taking notice of the seemingly infinite weaknesses in learning centers defenses. But why?
One of the primary reasons is that universities operate large corporate-sized networks, but without the budgets to match. Add to that, teachers and students aren’t given training to use and connect their technology in a safe way.
To avoid falling victim to devastating cyber-attacks which often have dire consequences, we share three lessons universities need to quickly take on board.
Your Research is Valuable to Cyber-Criminals
There is a hefty price tag on some of the research conducted by universities, which makes it particularly attractive to cyber-criminals. The University of Oxford’s Division of Structural Biology was targeted in February by hackers snooping around, potentially in search of information about the vaccine the university has worked on with AstraZeneca. It’s not just gangs of cyber-criminals targeting research facilities, last year Russian state backed hackers were accused by official sources in the US, UK and Canada of trying to steal COVID-19 vaccine and treatment research.
With world-leading research hidden in the networks of universities, its unsurprising that last year over half (54%) of universities surveyed said that they had reported a breach to the ICO (Information Commissioner’s Office). The research conducted by many UK universities makes them an attractive target for financially motivated cyber-criminals and state-sponsored hackers in search of valuable intellectual property.
To add insult to injury, ransomware attackers are doubling their opportunity for pay off by selling off the stolen information to the highest bidder, causing a serious headache for the victims while potentially increasing the value of their pay-out.
Personal Information of Students and Staff Can Easily Fall into the Wrong Hands
Based on tests of UK university defenses, hackers were able to obtain ‘high-value’ data within two hours in every case. In many cases, successful cyber-attacks are followed by not only a ransom note demanding payment for the recovery of frozen or stolen data, but also the added threat of sharing any sensitive stolen information with the public.

This week was filled with wide-scale calamity. Hundreds of millions of PCs have components whose firmware is vulnerable to hacking which is to say, pretty much all of them. It's a problem that's been known about for years, but doesn't seem to get any better. Likewise, Bluetooth implementation mistakes in seven SoC—system on chips—have exposed at least 480 internet-of-things devices to a range of attacks. IoT manufacturers will often outsource components, so a mistake in one SoC can impact a wide range of connected doodads. The most troubling part, though, is that medical devices like pacemakers and blood glucose monitors are among the affected tech. YouTube Gaming, meanwhile, wants to take Twitch's crown as the king of videogame streaming. But its most-viewed channels are almost all scams and cheats, a moderation challenge that it'll have to take more seriously if it wants the legitimacy it's spending big money to attain. In another corner of Alphabet's world, hundreds of Chrome extensions were caught siphoning data from people who installed them, part of a sprawling adware scheme.
