Highlights:

• 75% of organizations surveyed experienced a successful email-borne attack in the last 12 months.

• Recovering from an email-borne security attack costs victims more than $1 million on average.

• 69% of those hit by ransomware say the attack started with an email.

• Having a higher proportion of remote workers increases security risk and recovery costs.

Barracuda Networks, Inc., a trusted partner and leading provider of cloud-first security solutions, published its 2023 Email Security Trends report that shows how email-based security attacks affect organizations around the world. 75% of the organizations surveyed for the report had fallen victim to at least one successful email attack in the last 12 months, with those affected facing average costs of more than $1 million for their most expensive attack. 23% said that the cost of email-based attacks has risen dramatically over the last year.

The survey, conducted by independent research firm Vanson Bourne and commissioned by Barracuda, questioned IT professionals from frontline to the most senior roles in companies with 100 to 2,500 employees, across a range of industries in the U.S. and EMEA and APAC countries.

The fallout from an email security attack can be significant. The most widely reported effects were downtime and business disruption (affecting 44% of those that had been hit), the loss of sensitive, confidential, and business-critical data (43%), and damage to brand reputation (41%).

There were notable differences between industries. For example, financial services organizations were particularly affected by the loss of valuable data and money to attackers (cited by 59% and 51% of victims, respectively), while in manufacturing the top impact was the disruption of business operations (53%). For healthcare institutions the recovery costs involved in getting systems up and running again quickly were the most significant (44%). Regardless of size or industry, however, organizations with more than half their employees working remotely faced higher levels of risk and recovery costs.

Organizations also feel underprepared to deal with the threat of malware and viruses (34%), advanced email attacks like account takeover (30%) and business email compromise (28%), and even more basic threats like spam (28%).

“Email is a trusted and ubiquitous communications channel, and that makes it an attractive target for cybercriminals. We expect email-based attacks to become increasingly sophisticated, leveraging AI and advanced social engineering in their attempts to get the data or access they want and evade security measures,” said Don MacLennan, SVP, Engineering & Product Management, Email Protection, Barracuda. “Email-based attacks can be the initial access point for a wide range of cyberthreats, including ransomware, information stealers, spyware, crypto mining, other malware, and more. It is not surprising that IT teams around the world don’t feel fully prepared to defend against many email-based threats. Growing awareness and understanding of email risks and the robust protection needed to stay safe will be key in keeping organizations and their employees protected in 2023 and beyond.”
