Email Threats

Account Takeover

Whether through phishing, credential harvesting, data leaks or via the Dark Web, threat actors can compromise cloud accounts through various means.
A successful account takeover is one step closer to an attacker’s end goal – financial, knowledge-based or reputational damage to your business.

It takes a single account

Account takeover is an attacker’s dream – if successful they have access to everything that user has access to, including sensitive data and communications. ​
Once inside, they can use the trusted contact as a springboard to launch a further assault.​

A rising threat

Account takeover is becoming increasingly popular, with attackers purchasing credentials on the Dark Web rather than stealing directly from users, saving them the arduous task of cracking passwords.
Meanwhile, as more and more sensitive information is being stored on cloud accounts, the potential return for attackers has increased.
Identifying an account takeover:

Timeline of a typical account takeover

1
Attacker acquires credentials through a data leak, phishing campaign or credential stuffing
2
Account is breached successfully – attacker assumes identity of user and modifies log-in/authentication processes
3
Attacker does internal reconnaissance and moves laterally to escalate privileges and get closer to sensitive assets
4
Impact on the business can range from sensitive data loss to reputational damage, as attacker leapfrogs onto other contacts

Detection on multiple fronts

Many email security tools only look at a user’s inbox, rather than their full account activity. Account takeovers therefore fall outside their scope.
Most organizations have now implemented multi-factor authentication (MFA) tools to combat account takeover, but attackers are increasingly finding a way round even these defenses.
