Quickly Mitigating the Yammer Spammers

A non-profit foundation uses Yammer to collaborate with their broader community across the globe, many of whom aren’t technically inclined. Recently, bad actors received access to the non-profit’s Yammer platform through malicious links and spoofed those accounts. These spammers then used these accounts to send thousands of messages to internal channels, hack other accounts and inundate their networks. Microsoft was slow to respond to their calls for help, and the spammers were hacking more accounts by the minute.

Enter Aware! The non-profit set up a rule using Aware’s Signal application to filter messages that met the criteria of spam. Once they set up this rule, they were able to immediately detect these messages and automate their deletion. The Signal rule also helped them quickly identify hacked and spoof accounts.

Thanks to Aware, over 9,000 messages were caught and remediated. This non-profit has limited staff and addressing that many messages would have taken them hundreds of hours to manually delete.
