Hackers are using CAPTCHA techniques to scam email users
More email users fell for scams using CAPTCHA technology in 2020, a new report from security firm Proofpoint shows. The technique, which uses a visual puzzle to help authenticate human behavior, received 50 times as many clicks in 2020 compared to 2019.
That’s still only a 5% overall response rate, researchers note. Comparatively, one in five users clicked attachment-based emails with malware disguised as Microsoft PowerPoints or Excel spreadsheets. “Attackers don’t hack in, they log in, and people continue to be the most critical factor in today’s cyber attacks,” Ryan Kalember, executive vice president of cybersecurity strategy at Proofpoint said in a statement.
