Why the Microsoft Exchange Server Attack Isn’t Going Away Soon

On March 2, Microsoft revealed a critical cybersecurity offensive launched by a foreign adversary against organizations in the United States. The company attributed the attacks to a Chinese advanced persistent threat group it calls Hafnium. Microsoft quickly announced patches for the four previously unknown vulnerabilities in Exchange Server that the malicious actors had exploited. (By Cynthia Brumfield, CSO) Ingalls: After the Microsoft patches are implemented, it is a good idea to have a cybersecurity expert look for indicators of compromise on your Exchange servers to see if they were compromised. Cybersecurity teams have found that prior to the patch being applied, if a server was compromised, there was likely a backdoor uploaded to the server. The patch is not going to prevent the backdoor from being accessed. The backdoor is completely separate from the vulnerability.

Password Reuse Defeats the Purpose of Passwords

When a person reuses the same password across multiple accounts, one account’s exposure puts all the others at risk. To prevent this, cybersecurity awareness programs must emphasize the importance of passwords: how to create them, use them, and how to use a password manager with MFA. There are four forms of password reuse and they all are bad. (By Michael Schenck, CyZen.io, for Help Net Security) Ingalls: User names and passwords are no longer sufficient to protect accounts with sensitive information. By avoiding password reuse AND using multi-factor authentication, you can protect these accounts and reduce the risk of online fraud and identify theft. Here's a downloadable How-to-Guide for Multi-Factor Authentication that can help you better secure your information and identity online!
