Damage from this Microsoft Hack Could Linger for Businesses as the Fallout Drops
This week’s Microsoft hack landed third-party risk in the spotlight again after suspected nation-state hackers were able to exploit flaws in the code of on-premises Exchange server software to gain access to systems and data. The company reported the incident on their blog, stating “Today, we’re sharing information about a state-sponsored threat actor identified by the Microsoft Threat Intelligence Center (MSTIC) that we are calling Hafnium. Hafnium operates from China, and this is the first time we’re discussing its activity. It is a highly skilled and sophisticated actor.”
Organizations around the world from huge government agencies to small businesses have been affected by this cybersecurity disaster. One of the first agencies to report that they’d been impacted was the European Banking Authority (EBA). EBA officials say that personal data may have been accessed from its servers, and that agency IT systems like its email system have been taken down temporarily for remediation. Norway’s parliament has also announced that sensitive data had been accessed and extracted there in a breach linked to the Microsoft flaws.

While Microsoft has been strongly encouraging customers to transition their email to cloud-based technology, many companies and agencies still use physical email servers. Microsoft has now delivered patches that address the issue, but it will be too little too late for myriad users. Plus, companies may be slow to implement updates due to the complexity of Exchange’s architecture. Worst of all, the newly created patches do not remove any back door access that cybercriminals have left behind on compromised machines.
Experts anticipate many more incidents like EBA’s experience will be announced in the next few weeks, and the full impact may not be felt for months or longer. The suspected Chinese threat actors could potentially have seeded hundreds of thousands of victim organizations with tools that give them complete remote control over systems, and likely had access to sensitive data for a month or more. An estimated 30,000 organizations in the United States and 60,000 systems in Germany, including a significant number of small businesses, towns, cities and local governments, are likely victims.
