Cyber attacks are becoming more prevalent with increasingly damaging outcomes, presenting new cybersecurity risks to users.

But in spite of the ever-evolving threat landscape, many of the best defenses remain the same. This includes the basics like creating strong passwords and avoiding malicious links. Yet often, people take unnecessary risks due to convenience, among other factors.

This graphic shows the top cybersecurity mistakes in 2023, based on data from Proofpoint.

The Most Common Mistakes Made by Users

Below, we rank the most common risky actions that people made online in 2023, based on a survey of 7,500 end users across 15 countries:

Risky Action / Cybersecurity MistakeShare of Users Who Reported Taking This Action
Using work device for personal activities29%
Reusing or sharing password26%
Connecting without using a VPN at a public place26%
Responding to a message from someone they don't know24%
Accessing inappropriate websites20%

Overall, 71% of respondents said they made a cybersecurity mistake, with the vast majority doing so knowingly.

As we can see, the most common error was using a work device for personal activities followed by reusing or sharing a password. These actions were shown to be motivated by convenience, time-saving benefits, or urgency across users.

Ranking in third was connecting to WiFi networks in public spaces without using a virtual private network (VPN). This presents risks because when a user connects to public WiFi, it exposes them to potentially unsecured networks.

While most websites and services use Transport Layer Security (TLS) to encrypt credentials and personal messages, not all connections are secure.

Using a VPN can help prevents malicious actors from stealing personal information by masking a user’s location and other personal data while browsing the internet.

Top Cybersecurity Risks, According to Professionals

While the above data deals with the most common risks taken by users, the same report by Proofpoint also highlights the professional view around what risks are actually the most dangerous.

According to a survey of 1,050 security professionals, clicking on links or downloading attachments from someone that they don’t know was considered the most risky action users could take. By downloading an infected file, it exposes users to computer viruses and malware that mine a computer or device for personal data.

In addition, reusing passwords posed the second-highest security threat, followed by accessing inappropriate websites.

Overall, there is a strong degree of overlap between the top cybersecurity mistakes and the most common risks taken by users. In this way, it highlights how many respondents may be unaware of the scale of risk they expose themselves to, and the importance of using the basic tools to avoid financial losses and unwanted outcomes.

A Closer Look at The Top 20

Market capitalization (market cap) measures what a company is worth by taking the current share price and multiplying it by the number of shares outstanding. Here are the biggest tech companies according to their market cap on June 13, 2024.

RankCompanyCountry/RegionMarket Cap
13SamsungSouth Korea$379B
19PDD Holdings (owns Pinduoduo)China$212B

Note: PDD Holdings says its headquarters remain in Shanghai, China, and Ireland is used for legal registration for its overseas business.


Apple is the largest tech company at the moment, having competed with Microsoft for the top of the leaderboard for many years. The company saw its market cap soar after announcing its generative AI, Apple Intelligence. Analysts believe people will upgrade their devices over the next few years, since the new features are only available on the iPhone 15 Pro or newer.

Microsoft is in second place in the rankings, partly thanks to enthusiasm for its AI software which is already generating revenue. Rising profits also contributed to the company’s value. For the quarter ended March 31, 2024, Microsoft increased its net income by 20% compared to the same quarter last year.

Nvidia follows closely behind with the third-highest market cap, rising more than eight times higher compared to its value at the start of 2023. The company has recently announced higher profits, introduced a higher dividend, and reported that its next-generation GPU chip will start generating revenue later this year.

AI a Driver of the Biggest Tech Companies

It’s clear from the biggest tech companies that involvement in AI can contribute to investor confidence.

Among S&P 500 companies, AI has certainly become a focus topic. In fact, 199 companies cited the term “AI” during their first quarter earnings calls, the highest on record. The companies who mentioned AI the most were Meta (95 times), Nvidia (86 times), and Microsoft (74 times).
