Attackers have created a specialized economy around email account takeover

Barracuda released key findings about the ways cybercriminals are attacking and exploiting email accounts. The report reveals a specialized economy emerging around email account takeover and takes an in-depth look at the threats organizations face and the types of defense strategies you need to have in place.

Report highlights

• More than one-third of the hijacked accounts analyzed by researchers had attackers dwelling in the account for more than one week.
• 20% of compromised accounts appear in at least one online password data breach, which suggests that cybercriminals are exploiting credential reuse across employees’ personal and organization accounts.
• In 31% of these compromises one set of attackers focuses on compromising accounts and then sells account access to another set of cybercriminals who focus on monetizing the hijacked accounts.
• 78% of attackers did not access any applications outside of email.

“Cybercriminals are getting stealthier and finding new ways to remain undetected in compromised accounts for long periods of time so they can maximize the ways they can exploit the account, whether that means selling the credentials or using the access themselves,” said Don MacLennan, SVP Engineering, Email Protection at Barracuda.

“Being informed about attacker behavior will help organizations put the proper protection in place so they can defend against these types of attacks and respond quickly if an account is compromised.”
