At Cyble, we have promptly informed our clients about this alleged leak so that they can act on it. This leak is particularly important as it contains corporate email IDs. If the credentials are obtained by bad actors, there could be malicious use of the same in various ways such as business email compromise. 

Cyble has been reporting these types of breaches to spread awareness about the risks associated with them. 

We recommend people to: 

  • Never share personal information, including financial information over phone, email or SMSes. 
  • Use strong passwords and enforce multi-factor authentication wherever possible. 
  • Regularly monitor your financial transactions, and if you notice any suspicious activity, contact your bank immediately. 
  • Turn on the automatic software update feature on your computer, mobile and other connected devices wherever possible and pragmatic. 
  • Use a reputed anti-virus and Internet security software package on your connected devices including PC, laptop, and mobile. 
  • People who are concerned about their exposure in the Darkweb can register at AmiBreached.com to ascertain their exposure. 
  • Refrain from opening untrusted links and email attachments without verifying their authenticity.
