Security update notice - “zero-day” vulnerabilities in Microsoft’s Exchange Server

Last week, it was widely reported that four previously unknown or “zero-day” vulnerabilities in Microsoft’s Exchange Server software were being actively exploited by cyber attackers suspected to be associated with a foreign government. These defects could allow attackers to steal data or deploy malicious software to unpatched Exchange Servers. We began applying patches to address these vulnerabilities immediately after Microsoft made them available. In parallel, with the help of one of the cybersecurity firms credited with discovering these defects, we began looking for evidence as to whether we were affected. We can report that, to date, we see no evidence that these Exchange vulnerabilities have led to any unauthorized access to Vyper Networks’ or customers’ hosted Microsoft Exchange systems, applications, or data. The security and availability of customers’ data is our highest priority, and to that end we employ advanced threat detection technologies across our infrastructure that help us detect and block cyber-attacks. Our systems are monitored around the clock and critical security patches are applied when they become available. Any further patches that are released will be promptly applied.
