Excel is widely used by many of us to evaluate or analyze data. I’d like to briefly share a warning related to the use of Excel as there are currently 3 unpatched vulnerabilities that will most likely be addressed in the July MS updates
The ISC has a good summary today of in-the-wild and POC exploits associated with the 3 areas of risk. These are not prevelent in the wild and staying up-to-date on AV protection will help. Most importantly, avoid all untrusted documents or URLs in email.
