From the same article:
CrowdStrike is not sure how the hackers got in. The firm suspects they may have targeted DNC employees with “spearphishing” emails. These are communications that appear legitimate — often made to look like they came from a colleague or someone trusted — but that contain links or attachments that when clicked on deploy malicious software that enables a hacker to gain access to a computer. “But we don’t have hard evidence,” Alperovitch said.
Why does Alperovtich refer to APT 28 and APT 29 as “Fancy Bear” and “Cozy Bear”? Why use these colorful names rather than the accepted technical names? (APT stands for Advanced Persistent Threat).
Is he selling an idea, supporting a narrative?
