Dropbox109 process asking to access firewall on Yosemite

As the title says, I have a process called Dropbox109 asking to access the internet. I have denied it. I have Dropbox installed since Mavericks, and its been working fine (uploads/downloads/sync). What's suspicious is I got this Dropbox109 internet access request for the first time in a year of having Dropbox installed, and I couldn't find any information online.

Does anyone have any idea if it is a malicious program/virus or a legit process?

No, it’s a legitimate, routine request from Dropbox used to check your OS X version. Due to formatting limitations, I’m unable to directly embed this tweet from the official Dropbox support account. See the screenshot below, and click the link to view the tweet.
