Businesses often take the privacy and security of email for granted. But if there’s only one thing you take away from this information, it should be that email is the prime target for hackers and data thieves. There are hundreds of threats out there at any moment, and each of them have the potential to steal information, take control of your computer and network, and even damage your brand reputation. Below are 4 of the 13 email threats you should know about.
- Conversation Hijacking – Conversation Hijacking attacks are when hackers manage to replicate legitimate email threads between people to make it seem as though the victim is the one sending the messages back and forth. Make sure you have Multi-Factor Authentication (MFA) in place to keep the bad guys out of your email tenant.
- Account Takeover – Account takeover is when malicious third party attackers successfully gain access to a user’s account and credentials. Once the account is compromised, hackers monitor and track activity to learn how the company does business, the email signatures they use, and the way financial transaction are handled. This helps them launch successful attacks, including harvesting additional login credentials for other accounts. MFA is the best answer for this threat.
- Data Exfiltration – Data exfiltration is the unauthorized transfer of data from a computer or other device. It can be conducted manually via physical access to a computer and as an automated process using malicious programming on the internet or a network. Attacks are typically targeted, with the objective of gaining access to a network or machine to locate and copy specific data. There are specific monitoring tools that can watch for suspicious data movement.
- Lateral Phishing – With lateral phishing, attackers use recently hijacked accounts to send phishing emails to unsuspecting recipients to spread the attack more broadly. Because these attacks come from a legitimate email account and appear to be from a trusted colleague or partner, they tend to have a high success rate. MFA is crucial to minimizing this threat.
