Phishing is 1 of the most typical attack vectors for hackers who exploit finish-user behaviour as the weakest hyperlink in an organisations cyber-defence. For years, criminals have disguised attacks in emails and right now we see phishing emails as a main delivery technique for ransomware payloads.
