Top 10 Cybersecurity Threats of 2021

Happy New Year!  Now we are in 2022, we thought it would be a good idea to look back over the past year at the variety of cybersecurity threats that were prevalent.  Here are the 10 most popular and dangerous ones to look out for:

1.      Cloud Security Threats

○ As more companies adopt digital transformation, cloud migration has gained precedence. Cloud storage misconfiguration, inconsistent data deletion, and low visibility and access control measures have increased the cloud security vulnerabilities.

2.      Phishing Attacks

○ A phishing attack is one where the hacker emails you links or attachments, pretending to be someone familiar, say your boss or bank, but with an altered email address. Phishing attacks can lead to the loss of company-sensitive information, credential theft, ransomware attacks, and security breaches.

3.      IoT Threats

○ With the digital revolution, there is an increase in the usage of IoT devices like smart security systems, smart fitness trackers, that are vulnerable to cybersecurity threats. If an employee enters such an office building via keycard swipe or fingerprint recognition, the infected system would put the employee’s data at risk.

4.      Deepfakes

○ A Deepfake cybersecurity threat uses artificial intelligence and machine learning to manipulate an existing image or video of a person to show something that has not happened. Deepfakes have also been instrumental in creating more sophisticated phishing scams leading to business losses.

5.      Remote Work Threats

○ With the start of the pandemic, there has been an unprecedented rise in the number of remote workers. 2021 also saw several organizations opting for permanent work from home that led to an increase in hacker threats. Hackers can quickly break through the remote working environment by interfering with the VPNs that are improperly secured and hack the company servers. It leads to vulnerabilities to company-sensitive information.

6.      Insider Security Threats

○ Insider security threats involve malicious attacks and improper use of data, systems, and processes by employees. They can affect both small and big enterprises but smaller businesses are at a greater risk as employees can access more data and systems through internal networks than in large businesses.

7.      Social Media Threats

○ Cybercriminals are also targeting the social media presence of both individuals and businesses. This kind of attack includes announcing a fake event or fake product, leading the visitors to click a registration URL that leads to a fake website.

8.      Mobile Malware

○ Many remote workers are now using mobile devices for work online. This move from desktops to smartphones has increased the vulnerabilities to company-sensitive information. Attack due to mobile malware includes malicious software on a mobile device.

9.      Dronejacking

○ With drone jacking, cybercriminals use different types of drones to target users’ personal information. Drones are majorly used by camera crews, security systems, and law enforcement agencies. With improper security, they can control the drone hardware and pose security threats to organizations like Amazon that deliver essentials to customers.

10.  Malicious Advertising

○ Malicious advertising, also called malvertising, involves using online ads to spread malware. It is by adding a suspicious code into ads displayed on websites via legitimate online advertising networks. It includes “fake alert” attacks where a malicious ad can cause the target user to take harmful action in the interest of the hacker.
