The KnowBe4 security awareness training blog, in a post by Roger Grimes, advises that “Seventy to ninety percent of all malicious breaches are due to social engineering and phishing!” Those are deceptive e-mail or text messages for gaining private information for sinister purposes. Unpatched software is another source of digital risk.
“I’m asking you,” Grimes writes, “to ask yourself about when a hacker or malware got through your defenses, over your career and own personal experiences, how did it happen? It was probably social engineering and unpatched software, with social engineering leading the way. When you hear about a big compromise in the news, how did it happen? Probably social engineering and unpatched software.”
Grimes and other sources cited in Barrier Briefs posts make the point that alertness along with continually updated software are necessary for computer security. Don’t just coast along thinking you’re safe when you’re actually at risk.
