Hackers use a variety of methods, including credential stuffing and brute force attacks, to steal login credentials and gain unauthorized access to email accounts. Once these accounts are compromise, they can use them for other phishing attempts, data theft, or to spread malware.
Email Spoofing and Domain Impersonation
Hackers often spoof legitimate the largest content marketing companies in the us email addresses or domains to trick recipients into thinking emails are coming from trusted sources. This tactic is often used in phishing attacks, BEC scams, and other fraudulent activities, making it difficult for users to distinguish real communications from malicious ones.
Zero-Day Exploits
Zero-day exploits , which target the role of chatbots in affordable previously unknown vulnerabilities in email software or protocols , pose significant risks to businesses. Hackers can exploit these vulnerabilities to bypass security defenses and launch highly target attacks.
Social Engineering Tactics
Hackers also use psychological manipulation techniques to trick individuals into taking actions that compromise security. This can consumer data include leveraging social media credentials to create convincing phishing emails or fabricating pretexts to obtain sensitive information from unsuspecting individuals.

Mobile Device Threats
As the use of mobile devices for business communication increases, so do the threats targeting mobile email applications. These threats include malicious applications, network spoofing, and device hijacking.
Insider Threats and Human Error
Despite technological advances, insider threats and human errors continue to contribute significantly to email compromise incidents. Whether intentional or unintentional, actions by employees or trust partners can inadvertently expose sensitive data or compromise email systems.
Botnet Messages
A botnet is a group of infect computers controll by a single user or hacker. These devices can be use to send spam, deliver viruses, and other attacks.
