But a person with direct knowledge of the situation who was not authorized to discuss the matter publicly and spoke on condition of anonymity said the NRA has had problems with its email system this week — a potential sign of a ransomware attack. Ransomware attacks have spiked in recent years against all manner of companies and organizations, but rarely are the targets as politically sensitive as the NRA.

The NRA spent tens of millions of dollar in the past two presidential elections trying to help Donald Trump. However, there are a few actions that organizations can take to help mitigate risk and limit the fallout of a ransomware attack. The most important thing that organizations can do is make sure that they regularly and consistently back up data , but filter out potentially malicious websites and emails.

At that point, you should probably consider upgrading to a full security suite. After all, it's your business's security on the line. Even for personal use, most for-pay antivirus tools offer more than their free counterparts—sometimes a lot more.
