However, the good news is the rates of phishing emails are lowering year after year. While the world registered a peak annual spam rate of 69% in 2012, currently, it’s less than 50%.

3. Gmail Protection Service Blocks More than 100 Million Phishing Emails Every Day

No matter how small or big one’s business is, IT teams face a lot of difficulties in navigating the challenges of the COVID-19 pandemic.

However, one thing remains constant, and security is still at the top of everyone’s priority list. Phishing, being one of the most common cyber threats, is highly used by cybercriminals to access sensitive data.

A malicious person generates new attacks and scams each day to take advantage of the uncertain pandemic days.

Currently, over 1.8 billion people use Gmail each month, and around 5 million business establishments use the same in the workplace as a part of G Suite.

One reason behind the immense popularity of Gmail among its users is its built-in security protections.

When researching the number of phishing emails sent each day, Google statistics about spam in April 2020 revealed that its service blocks over 100 million phishing emails every day.

The company explained that the increase in phishing attacks is because the scammers are using the Corona pandemic as an opportunity to deceive people and businesses.

That’s why they easily trick victims into providing sensitive personal and business information.

As per the latest reports from phishing email statistics, around 1.385 million phishing sites were generated each month in 2021.

The cyber attackers create these sites hoping that some unsuspecting users will fall for their vicious trap.

As more businesses are experiencing disabling security breaches, the flood of compromised data is on the way up.

Businesses are still not fully prepared for breaches despite data breaches being common these days.

Spam is annoying, and it can even be dangerous sometimes.

Surprisingly, despite being annoying and dangerous, users often check their spam or junk folders.

Around 11% of the users said they check their spam folder every hour, and another 47% said they check spam inboxes at least once a day.

That means 58% check spam emails daily, while only 25% check it once weekly. And only 17% check it less than once a week.

13. Around 20% of All Employees in The Business Establishment Are Most Likely to Click on A Phishing Email Link

Regardless of how well-trained employees are (well, 95% of business establishments claim that they train their employees), phishing attacks are so sophisticated that employees, many a-times, accidentally click on a phishing email link and fall for the traps of cybercriminals.

Recent data shows that around one-fifth (20%) of employees are likely to click on a phishing email link accidentally.

Thus, it is pretty evident from the data that education alone can’t help when it comes to a phishing attack.
