Background for this topic.
Email is a system for exchanging digital messages, typically using mail servers and clients over a network. In security, it includes both the messages and the accounts, servers, domains, and authentication mechanisms that handle them. Email commonly carries phishing links, malicious attachments, and fraudulent requests for payments or credentials; compromised accounts can also be used to impersonate trusted people and conduct further attacks.
Defenses include filtering and malware scanning, phishing-resistant multifactor authentication, careful handling of links and attachments, and monitoring for unusual login or sending activity. Domain controls such as SPF, DKIM, and DMARC help receiving systems detect messages that are forged or sent without authorization, while encryption protects message contents in transit or at rest when correctly implemented. Security teams should preserve relevant headers and mailbox activity so suspicious messages can be investigated, removed, and used to identify affected accounts and other recipients.
The emerging threat group is the latest to adopt the combo attack tactic, which Black Basta and other groups already are using to gain initial access for ransomware deployment.

A 3AM ransomware affiliate is conducting highly targeted attacks using email bombing and spoofed IT support calls to socially engineer employees into giving credentials for remote access to corporate systems. [...]
It takes just one email to compromise an entire system. A single well-crafted message can bypass filters, trick employees, and give attackers the access they need. Left undetected, these threats can lead to credential theft, unauthorized access, and even full-scale breaches. As phishing techniques become more evasive, they can no longer be reliably caught by automated solutions alone
