"The Attack That Broke Twitter Is Hitting Dozens of Companies"

Hackers used a social engineering technique called "phone spear phishing," also known as "vishing" or "voice phishing," in an attempt to compromise more than 100 Twitter accounts belonging to high-profile users, including CEOs, celebrities, and politicians. The hackers succeeded at taking control of 45 of those accounts to send tweets promoting a bitcoin scam. According to cybersecurity investigators, in the last month since the Twitter hack occurred, banks, cryptocurrency exchanges, web hosting firms, and other companies have been targeted in attacks involving the same phone spear phishing technique. This article continues to discuss the performance of phone spear phishing in the Twitter hack last month and the increased use of this type of phishing against different companies following the incident.
