Biggest Cyberattacks of 2021

Published

 on

2021 came, and with it came the wave of emerging technologies in various sectors, be it medical, sustainability, blockchain technology, and much more. And while 2021 wasn’t as intense as its predecessor, the year still brought with it some challenges that were quite an ordeal to overcome, or even avoid, for that matter. With this year came some of the most extensive cybersecurity infiltrations up to date. So, let’s guide you through some of the biggest cyberattacks of 2021.

A cyber breach is the most effective way for hackers to obtain what they seek by accessing an organization’s networks by targeting information systems’ infrastructures, computer networks, or personal computer devices. This occurs by employing diversified types of cybersecurity attacks to steal, change, or even damage data or information systems.

Cyber breaches on some major global organizations have left companies and governmental entities questioning their ability to safeguard their cybersecurity infrastructure and protect their consumers’ and employees’ data.

Throughout 2021, cybercriminals worldwide made it their mission to exploit any security weakness of any organization for their vendetta, be it for cryptocurrency ransoms, or to access and obtain data – the most precious asset of our time.

According to Identity Theft Resource Center (ITRC) research, the accumulative number of cyber breaches through September 30, 2021, already surpassed that of 2020 by 17 percent, “with 1,291 breaches in 2021 compared to 1,108 breaches in 2020,” according to Security Magazine.

While a cyber security breach is mainly directed at organizations hackers are targeting, and the damage is not confined within the borders of the company or agency, consumers are also affected given their data is being accessed and used as collateral for cybercriminals to get what they want.

So, let’s dive right into 2021’s recent cyber security breaches.

Kaseya

In July, a ransomware group that goes by the name REvil gang caused one of the most memorable cyber heists of all time. By manipulating a flaw in Kaseya’s on-premises virtual storage appliance (VSA), remote monitoring, and management tool to encrypt data and seek payment from almost 1,500 of Kaseya’s end-user customers.

The cyber security breach weaponized REvil with the needed means to take advantage of the VSA’s basic efficacy to deploy ransomware to customers. The breach paralyzed more than 36,000 managed service providers (MSPs), with no access to the company’s VSA product for almost ten days.

As for REvil, the cybercriminal group demanded the heftiest ransom in the history of cyber-attacks. On July 4, the group asked for $70 million to deliver the universal decryptor key for all the victims exposed to the cyber security breach.

However, Kaseya never ended up paying the ransom money and nineteen days after the breach, it gained access to the key, which in return – with the help of Emsisoft – helped it in unlocking customers’ ransomed files.

Acer

In March, the same group responsible for the Kaseya breach claimed that it had also broken into Acer’s servers and accessed unencrypted data. On their official site, the infamous group publicized alleged images from its financial sheets, bank balances, and bank communications.

On March 14, REvil communicated with Acer, stating that it is willing to offer the giant a 20 percent discount if PC titan finalized the ransom payment by March 17. In parallel, the group’s affiliates revealed that they are willing to deliver a decryptor, a vulnerability report, and delete the stolen files.

After not receiving an answer from the Taiwanese giant, REvil demanded a $50 million ransom on March 19.

The Colonial Pipeline Attack

In May, the U.S. suffered from one of the most damaging cyberattacks to date. Deemed the biggest cyberattack of 2021, the colonial pipeline infiltration shut down a 5,500-mile natural gas pipeline – of one of America’s largest oil and gas companies – for five days. The infiltrators? A ransomware group known as, DarkSide.

Darkside managed to gain access into the Colonial Pipeline networks, resulting in more than 10,000 gas stations across Southeastern America running out of fuel. Following the breach’s discovery, Darkside publicly threatened to expose almost 100 gigabytes of data.

The organization ended up paying a $4.4 million ransom on May 8, hoping the money would reinstate operations for its pipeline as soon as possible. While the ransom was already paid before restoring functions, federal officials managed to retreat most of the money.

“The Colonial Pipeline attack made such an impact because the pipeline is an important part of the national critical infrastructure system. Taking the system down disrupted gas suppliers all along the East Coast of the United States, causing chaos and panic,” Touro College Illinois Cybersecurity Program Director Joe Giordano said in a statement.

CAN Financial

Chicago-based insurance company, CNA Financial, was exposed to a cyber breach in March of 2021, where thousands of employees, contractors, and policymakers’ information got exposed.

The breach directly impacted more than 75,000 personas: revealing names, private identification, and social security numbers.

The cyber security breach left behind a disruption in CAN’s network, impacting significant systems, as well as corporate email. In parallel, it flatlined the functionality of the company’s site, decreasing it to a static display.

According to CAN’s statement to the Securities and Exchange Commission (SEC), there was a high chance the company’s insurance policy might not cover the damage created by the attack.

In the end, the insurance mogul ended up paying the infiltrators a $40 million ransom by the end of March, only two weeks after a mass of CAN data was obtained and company officials could not access their network, according to Bloomberg.

Despite initially planning to disregard the cybercriminals’ demands while it pursues alternatives to re-obtain the stolen data, eventually CAN succumbed and began negotiations with the hackers, a move that placed it in some of the biggest cyberattacks of 2021.

The cyberattacks of 2021 have left businesses and governments questioning the sustainability of their cybersecurity infrastructures. Cybersecurity threats are perceived as the ever-growing enemy, exposing national and public security, and economic challenges to grave hazards.

As the world further intertwines through technology, people and communities from all around the globe connect, socialize and organize themselves through cyberspace. Cyber security breaches are subjecting organizations and governments to tremendous pressures to safeguard their data, with many establishments and federal agencies aiming to seek out the threat before it occurs.

Password Management in Network Security

When it comes to ensuring the highest levels of cybersecurity for any establishment, password management in network security is one of the most paramount factors in guaranteeing security. As one of the essential cybersecurity measures, password management is a critical element for any online activity, whether for software or hardware. Everything is protected with a password.

What is Password Manager and How does it Work?

To those not familiar with the concept, password management’s significance exceeds the creation of a strong password to protect your data or account. It is a cybersecurity system. A system that manages any saved login credentials, all while guaranteeing a safeguarded relocation of data from one device to another. When coming up with a valid password, a few factors must be taken into account, such as the potential of being exposed to high risks and identity theft.

For any establishment, the correct password manager helps to monitor any activity and amounts of logins for servers people work on. As a software application, it is developed for storing and managing online credentials. With the increased available platforms and programs requiring safety credentials, the risk of losing or forgetting a password has never been higher. User password management, such as Google password manager, helps users with a handful of passwords for essential web applications.

By providing the needed digital space to generate and store any, and all passwords in one location, password management in network security keeps any data safe and secure in various ways, including biometrics data.

Why Use Password Manager?

Through the encryption of users’ logins, a reliable password manager protects your credentials and cannot be accessed until the master password is submitted. In this case, no password is stored on the device itself or even on the manager’s servers. While some might think that storing all of your important passwords in one place might be hazardous, the truth is, password managers are the safest bet to safeguard all your passwords, as the chances of a password manager being breached are extremely low and almost very unlikely to happen.

Without getting into all the technical terms as to why password managers are the safest option, these applications can be perceived as the lesser evil. While users will still need to create one master password – preferably to be long and a bit complicated – it will guarantee the protection of any login credential for any account or credit card information.

The ideal password managers to download are backed by two-factor authenticators, where users are asked for a one-time code alongside the password whenever a new login into a new device takes place.

Password Management Best Practices in Network Security

In terms of obtaining the highest level of protection for network security, few practices are applicable to almost anyone to ensure the highest level of user password management.

1. Training

Training the team and raising awareness of potential password threats is one of the most important things to consider. Team members working on network security have to understand the risk of cybersecurity and the importance of implementing the right measure to protect and secure any account credential.

2. Enforcement of Reliable and Strong Passwords

Enforcing the creation of strong passwords and establishing they follow the best practices for network security to protect the network and its data while respecting the integrity, confidentiality, and accessibility of the network’s computer systems.

This includes performing a thorough network audit, deploying network and security devices, disabling file sharing features, updating antivirus and anti-malware software, securing all routers, using a private IP address, and finally establishing a network security maintenance system.

3. Multi-factor Authentication

Endorsing your password management with two-factor authentication is like adding another solid layer of protection to your accounts and their passwords. Multi-factor authentication ensures that only people responsible for the network have access to its sensitive data.

How to Check a Suspicious Link Without Opening it

Published

 on

We are all well aware of the troubles opening a fishy link can lead us to.  Luring users to click on a given link has been of one the well-known techniques to get access to the device, install virus and malware or even go as far as creating a full ransomware attack. To protect your computer and private information, there are multiple techniques to check links without opening them. What is important though is never to open the link if it is suspicious.

When you are not dealing with a shortened URL, the best way to go thoroughly through the link to see if there is any spelling mistake. Attackers usually tend to change a minimum number of letters so that you are unable to tell the difference. For instance, things like www.goagle.com instead of www.google.com should catch your attention with the second ‘o’ of Google replaced with an ‘a’.

Emails are the best sources for phishing attacks. These kinds of attacks are used to steal some sensitive information such as passwords and credit card information. The best way to avoid these kinds of attacks is to authenticate the sender. For that purpose, do not only check the name of the sender, you need to double-check the email the sender is using. In general, attackers use credible sender names with emails which do not correspond to the promoted identity. Next time you get an email from your bank like “XBank”, check that the sender email is person@Xbank.com rather than person@anyothermailclient.com.

Many websites actually provide link checking or link scanning features. This is a very neat technique to simple check the link before clicking on it.

VirusTotal

www.virustotal.com  is an excellent website for this task. This online tool practically does the job of an anti-virus. When you go to the website, you have the possibility to analyze files and URL for malware or any other security breach. Once you submit your file or enter the URL, the website will use different tools and software, then provide you with a detailed output from each of these tools. If you are unsure if a given software is credible enough, you can compare it to the output of other platforms on a single website.

Use a Short URL Expander

Sometimes attackers try to shorten URLs to hide any malicious intention. Analyzing shortened URL is not straightforward. To overcome this problem, copy the provided URL without opening it and use specific websites that actually expand the provided URLs. Then, you can analyze the original URL for possible security breaches.  Many websites are there to do this task. Just search for “short URL expander” on your search engine and use the top provided websites.

Upgrade your Anti-Virus with Internet Security Features

Anti-virus software is commonly used to protect personal computers from viruses and other malware. While these are available for free, you can easily upgrade them to include internet security features for a small monthly fee. This will bring major improvement to your internet browsing experience including custom-made safe browsing tools.

Use Google Transparency Report

Google provide a nice tool to check for the safety of websites. To do so, visit https://transparencyreport.google.com and enter the URL in question. The Google source will then provide you with a safety report of that website.  

The nicest solution is kept to the end. When you hover over a link in your email client or web browser, a small square appears including all the information related to the chosen URL. These details can be used to give a preliminary indication whether to trust the source.

Final Thoughts

Suspicious links are everywhere! To make sure they don’t catch you by surprise, follow the highlighted and you’ll be safe to go.

Disadvantages of AI in Cybersecurity

Published

 on

Cybersecurity and artificial intelligence (AI) are two very trending topics at the moment. AI has been the pivotal elements modifying business strategies, improving decision-making processes, and triggering automation in every industry in the world. The latest sentience debate is a clear indicator on serious and advanced AI is becoming nowadays. Cybersecurity is the other important element of today’s technological world. With an increasing reliance on data and the move to online services that require an individual’s biometrics, security essential in preventing data thefts and associated cybercrimes. AI has undeniably improved cybersecurity practices by allowing a real-time analysis of internet traffic to discover possible threats at the earliest and take defensive actions. This important learning process hides however several disadvantages of AI in cybersecurity.

What Are the Downsides to AI in Cybersecurity?

The touted advantages of AI in cybersecurity are real and very useful. However, the increasing adoption of AI solutions for security is actually causing problems at different levels.

Hackers Use AI as Well

When it comes to maturity in technology, hackers are the best at it. These individuals sitting behind computer screens logging data and doing advanced analytics to identify any loophole or vulnerability they can use to their benefits. The use of AI as far as cybersecurity is concerned is a double-edged sword. It is actually a race of who can develop a better algorithm that caters better to the data which is circulating online. In this sense, the use of AI is a big threat to security.

Another issue is that while a company is analyzing and learning from data to discover threats, a hacker is concurrently analyzing the company’s cyber-defense mechanisms and policies to find “open doors’ that will take it into the system to complete the intended attack.

Data Confidentiality

AI algorithms are associated with the analysis with large volumes of data, a key requirement for the developed algorithms to produce accurate outputs. The data a company deals with contains normal traffic related to daily transactions and activities, but also sensitive information related to the clients including their biometrics and personal information. What happens to our data when it goes to the AI-agent though is another thing. Protecting the data is key when AI is used for cybersecurity reasons. The secrecy of the clients’ data should not be compromised for any reason.

Increasing Need for Data

The field of cybersecurity is constantly evolving with ingenious attacks and threats emerging every now and then. Browser-in-the-browser attacks and increasingly advanced ransomware attacks have been notable examples in 2022. In order to discover attacks at a later stage, the AI algorithm needs to have data to do the proper training. The increasingly dynamic environment with threats emerging and evolving will lead to a surge in the required volumes of data, which can potentially not be readily available to have a fast response to the attack itself. Whether it is the ability of AI to keep track of the exponential growth in data or the availability of data for the AI-algorithm to produce results is a big disadvantage of this approach for cybersecurity

Will Cybersecurity be Replaced by AI?

With the drive towards more and more automation, it is questionable whether this can be applied as well for cybersecurity practices. AI can certainly assist in processing and learning from data and produce insights. However, the real decision maker in such as sensitive area where no errors can be tolerated is the cybersecurity expert himself. The only way for AI to replace cybersecurity is when it becomes sentient or developed enough to think and act like humans do. There is still a long way for that to concretize.

Explainable or interpretable AI is a key intermediate step in reaching this target. First, we need to understand how AI produces results. Proper cybersecurity practices require a reduction in bias while optimizing the performance of the algorithm.

How Will AI Affect Cybersecurity Jobs?

The adoption of AI will certainly cause major shifts in the cybersecurity job market as in the case in other industries, but probably at a smaller scale. The level of skill and experience needed to thwart cyberattacks will safeguard the need for security experts to provide the final decision regarding suspicious data patterns.

On the other hand, the incorporation of AI will call for new skilled workers that can manage and optimize the performance of the algorithms. Another alternative would be for existing workforce to be upskilled and retrained to handle the new analysis tools.

Summary

As data is becoming the basic unit for decision making, AI has invaded all industries and businesses, including cybersecurity. Companies are starting to incorporate learning algorithms to their offered services in order to have a more intelligent management of the different security threats. However, the role of AI in cybersecurity should be considered with enough judgment. The addition of AI would increase the complexity in the data management process, notably in terms of data privacy and the continuous need for more data.
