New Microsoft Excel Vulnerability Found
A day after Microsoft released 12 patches that fixed 21 vulnerabilities, including an exploit in Word, it appears that reports of a new vulnerability in Microsoft Excel are surfacing.
Here’s what we know: In order for this attack to be carried out, a user must first open a malicious Excel document that is sent as an email attachment or otherwise provided to them by an attacker. (note that opening it out of email will prompt you to be careful about opening the attachment) So remember to be very careful opening unsolicited attachments from both known and unknown sources.
There probably will not be a patch until the next Patch Tuesday so be on the lookout for any malicious activity that may attempt to exploit this vulnerability.
