THE NATIONAL Privacy Commission (NPC) on Monday warned the public against the misuse of the carbon copy (CC) function of e-mail apps, saying it could lead to phishing and privacy violations.  

“We have observed the high number of human errors, specifically the inadvertent use of the CC function, as a cause of security incidents, which have risen in number since 2021,” the agency said in a statement. 

“Such errors have led to unintended data exposure, potentially compromising the privacy and security of the data subjects involved,” it added. 

The carbon copy function displays the e-mails of all recipients to everyone who gets the message. “This may result in unintentional disclosure of personal information, which may lead to spam, phishing attempts or targeted attacks,” it added. — Revin Mikhael D. Ochave
