Cyber Espionage, Microsoft released mitigation measures for Exchange server

Microsoft released mitigation measures for Exchange server. However, the company warns: Are not a remediation, nor are they full protection against attack. The ATPs threat is still active

Microsoft released mitigation measures for organizations who are unable to apply immediately the latest patches for Exchange server. The company, however, underlined on its blog that “these mitigations are not a remediation if your Exchange servers have already been compromised, nor are they full protection against attack”. It also provided a nmap script to help customers discover vulnerable servers within their infrastructure. According to the cybersecurity researchers, multiple state sponsored cyber-espionage APTs have been targeting vulnerable Exchange servers. There are reports of more than 30,000 organizations hacked via the flaws. Moreover, as the White House press secretary Jennifer Psaki stated in a press briefing, “this is an active threat. Everyone running these servers needs to act now to patch them. We are concerned that there are a large number of victims and are working with our partners to understand the scope of this.”
