Businesses are under siege from a barrage of phishing email every day, making it hard for IT professionals to execute a successful defense against email-based cyber threats. Unfortunately, today’s phishing messages can be a problem for employees to spot, creating a major data loss threat for businesses. Making the challenge even harder, cybercriminals are constantly stepping up their game to bypass many traditional email security measures and lure their targets in with hard-to-detect messages – and 97% of employees are unable to detect a sophisticated phishing message.

Data Loss Via Email is a Major League Risk
Email is the riskiest channel for data loss in an organization. In a recent study, 65% of IT security practitioners cited email as their biggest data loss risk, followed by cloud file-sharing services (62%) and instant messaging platforms (57%). Much of that data loss was the result of improper employee behavior including mistakes and malicious insider activity. The leading cause of data loss incidents (40%) was employee negligence like the failure to comply with data security policies. An estimated 23% of organizations in the study experienced up to 30 security incidents involving employees’ use of email every month ranging from sending the wrong file to interacting with a phishing message.
Another major challenge that IT professionals face is a lack of visibility into the sensitive data that employees transferred from the network to personal email. This was cited as the most common barrier to preventing data loss via email in 54% of organizations. About 50% of respondents reported being unable to identify legitimate data loss incidents and lack of insight into standard employee data handling behaviors as major obstacles in their fight to prevent data loss through email for their organizations.

Malicious Insiders Complicate the Picture
Of course, some data loss via email can be chalked up to a source that no one wants to think about: malicious insiders. Unfortunately, not everyone in an organization is really on the same team. This growing problem is a driving contributor to data loss. In this study, researchers determined that 27% of the data loss incidents they studied were caused by malicious insiders. Making matters worse, malicious insiders also have the power to cause data security incidents that take a long time for IT personnel to detect. It can take organizations up to three days to detect and remediate a data loss and exfiltration incident caused by a malicious insider via email.
So, what are they looking for? Malicious insiders overwhelmingly want one thing: money. One quick way for them to get it is to steal valuable data to sell in the booming dark web markets. The most common types of confidential and sensitive information lost or intentionally stolen in the incidents studied includes customer information (present in 61% of incidents); intellectual property (56% of incidents); and consumer information (47% of incidents). Malicious insiders can hide anywhere in an organization, but they do have a few favorite departments to target.

The Roots of The Perilous State of Email Security Risk Today
In order to get a solid grasp on the essence of today’s email threats, especially threats that could lead to data loss, it’s important to understand the factors that make up today’s email landscape. These trends underpin the business email security picture right now and offer a snapshot of what could influence the email security picture in the months ahead.
Phishing-Related Cyberattacks & Losses Are Booming
- Business email compromise losses increased 28%
- Ransomware attacks and losses grew over 50%
- Social media-related phishing attacks grew more than 80%
- Brand impersonation and spoofing was 15 times higher in 2021 than in 2020
- Total cybercrime losses increased by almost 50%
Phishing also paved the way for a parade of damaging cyberattacks, and far too many businesses just weren’t ready to face the threat to their detriment.
- An estimated 84% of businesses said they were the victims of a successful phishing attack.
- About 59% of organizations that fell victim to a phishing attack were then infected with ransomware.
- Just over 40% of network intrusions were facilitated by phishing.

High Email and Phishing Volume Has Increased Security Stress
In 2021, 319.6 billion email messages were sent — up from 306.4 in 2020 — and email volume is expected to jump to 376.4 billion messages in 2022. Unfortunately, an increase in email volume is also an increase in the volume of phishing messages that an organization’s email security system has to handle.
That’s reflected in reporting from the U.K. Information Commissioner’s Office (ICO). That agency recorded 150,317 phishing attacks in January 2021, which dramatically increased to a startling 4,135,075 in December 2021 — an increase of 2,650%.
Some of their other findings were:
- Malicious spam shot up by 2,775% between January and December 2021.
- Phishing messages climbed 20% between January and December 2021.
- Malware attacks in 2021, commonly carried through phishing, boomed with a 423% increase.
