Businesses Using Microsoft Exchange Beware
By Diane Tait Image courtesy Pixabay If your business uses Microsoft Exchange, you may have a problem. That’s because in February 2021, a Chinese hacking group called Hafnium exploited flaws in Exchange to gain access to email accounts. This allowed the state-sponsored hackers to install malware that could ultimately let them take control of affected systems. The estimated number of compromised accounts is more than 100,000. So flagrant was this attack that the Cybersecurity & Infrastructure Agency, issued a warning along with appropriate steps to take to mitigate the attack. The Hafnium exploit can allow hackers to steal data, encrypt existing data, delete data or even hold data for ransom.
