Twilio Hack Targets 33M Authly Users, Many in Crypto

Crypto users are on alert after a recent hack revealed information about popular 2FA app users. On Thursday, July 4, Twilio confirmed a data breach of its app Authly, affecting 33 million people.

Twilio emphasized that no evidence suggested the hackers had accessed their internal systems or obtained other sensitive data. However, they did advise users to take action to protect themselves from future scams or hacks. 

What Users Need to Do After the Authly Hack

Twilio advised all Authly users to immediately do the following steps to prevent potential privacy breaches and financial losses: 


  1. Update Security Settings: Ensure that your Authy app and other security applications are updated to the latest versions.
  2. Disable Multi-Device Functionality: This prevents unauthorized access to 2FA tokens, even if the phone number is compromised.
  3. Be Vigilant Against Phishing Attacks: Phone number leaks often lead to phishing attacks, where criminals pose as trusted entities to scam their victims. Users should be vigilant of any unsolicited messages or calls requesting personal information or login credentials.

By following these steps, Authly users can greatly reduce the risks of scammers taking advantage of them.    

On the Flipside

  • Phishing attacks are becoming increasingly common in crypto. For instance, in April, scammers used phishing ads to target Etherscan users
  • While phishing is common, scammers get the most money from “spear phishing,” targeting specific, high-value targets.  

Why This Matters 

While the Authly hack did not reveal sensitive information, it did expose users to potential phishing. Users need to stay vigilant over potential future scams coming their way.
