Cybersecurity has never been more important for every level of our government.
The hacking attempts at major federal agencies have raised the profile of nefarious actors who use their highly advanced cyber skills to exploit both security and the vulnerabilities created by human error. Just last month, the Department of Defense confirmed that computer systems controlled by the Defense Information Systems Agency had been hacked, exposing the personal data of about 200,000 people. Additionally, the Department of Justice recently charged four members of the Chinese military for their roles in the 2017 Equifax breach that exposed the information of 145 million Americans. The hackers were accused of exploiting software vulnerability to gain access to Equifax’s computers. They are charged with obtaining log-in credentials that they used to navigate databases and review records.

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.

Experts often consider biometrics security the next big thing in cyber security. It encompasses a broad category that includes verifying a person's fingerprint, iris, gait and other factors that should be unique to the person checked. However, various tests proved that some biometric-based security has substantial room for improvement For example, researchers have hacked into smartphones that have fingerprint scanners by pressing the print of the rightful owner into a piece of Play-Doh and holding that impression against the reader. What those results indicate is that people should not assume that biometrics options are a foolproof choice for cyber security needs.

Researchers at security firms including Sentinel One and Drago’s have been mystified by a piece of code named Ekans or Snake, over the last month. Drago’s publically released its full report on Ekans Ransomware that has recently inflicted Industrial Control Systems and these are some of the most high-value systems that bridge the gap between digital and physical systems. In the history of hacking, only a few times a piece of malicious code has been marked attempting to intrude Industrial Control Systems. Ekans is supposed to be the first Ransomware with real primitive capability against the Industrial Control Systems, software, and hardware used in everything from oil refineries to power grids. Researchers say this ransomware holds the capability to attack ICS by Honeywell and GE as well.
