According to F-Secure, over one-third of all security incidents start with phishing emails or malicious attachments sent to company employees. Emails are still the weakest link in security chain.
An email has shifted to an essential part of daily life that many businesses rely on email services now as a central communication tool to deliver official documents, and have a business conversation. Email is also important for individual users to stay in touch with friends, chat with colleagues etc.
However, the mail also provides the best ways to cybercriminals for infiltrating into their targets. Because it is easy to hide under a fake email account and trick user.
According to F-Secure’s report, email risks still pose a great danger to businesses.
Type of Attacks
The single most common source of breaches analyzed in the report was attackers exploiting vulnerabilities in an organization’s Internet facing services, which is 21 percent of security incidents investigated by F-Secure’s incident responders. 
Phishing 16% and emails with malicious attachments 18% together accounted for about 34% of breaches.
Cybercriminals use basic social engineering schemes such as sending fake emails, rather than hacking into systems. There are a lot of different ways different attackers can use email, and these attacks are popular because almost every company relies on email for communication. Therefore it important to think before they click on attachments
1- Email is the weakest link in security chain
Other significant findings in F-Secure report include:
- Organizations were hit by targeted and opportunistic attacks in nearly equal proportion to one another
- Insider threats accounted for one-fifth of security incidents
- Incident responders were contacted after the security perimeter was breached in nearly 80 percent of cases
- The most common post-breach action taken by attackers was spreading malware (mostly for financial gain, but also for espionage or maintaining access for future purposes)
- 13 percent of investigations turned out to be false alarms.
2- Effective Solutions Against Email-based Attacks
To bring an effective solution, people, process and technology elements must be included in cyber security measures that the three of the elements must be applied to take the necessary steps against the security threats in a rmonious way to keep cyber security at balance.
