On March 2nd, 2021, Microsoft reported discovering 4 new vulnerabilities in its Exchange Email Server. According to a statement on their website, the company “detected multiple 0-day exploits being used to attack on-premises versions of Microsoft Exchange Server in limited and targeted attacks. In the attacks observed, the threat actor used these vulnerabilities to access on-premises Exchange servers which enabled access to email accounts, and allowed downloading of additional malware to facilitate long-term access to user environments.”
What to Do Now and in the Future
Microsoft is urging their customers to update their on-premises systems right away and has said that Exchange Online has not been affected. While the exact number of worldwide attacks is still unknown, sources say it could be as many as 250,000 Exchange customers. The attack has been attributed to the Chinese network of hackers known as “Hafnium”.
Many businesses are now left wondering if their networks have been compromised and worrying that their data may be in danger of being stolen in the future.
Here are 3 important lessons all businesses can learn from the attack:
- Security Systems are a Must in Order to Prevent Future Attacks
The right operating systems solution can protect you from spam, phishing, and viruses.
