Facebook Cracks Down on Groups Spreading Harmful Information
Facebook said Wednesday it is rolling out a wide range of updates aimed at combating the spread of false and harmful information on the social media site stepping up the company's fight against misinformation and hate speech as it faces growing outside pressure.
The updates will limit the visibility of links found to be significantly more prominent on Facebook than across the web as a whole, suggesting they may be clickbait or misleading. The company is also expanding its fact-checking program with outside expert sources, including The Associated Press, to vet videos and other material posted on Facebook.

D-link router under attack
D-Link Routers Are Under Attack
The four D-Link models targeted are the following, according to the security firm Bad Packets, which issued a report on the crime campaign.
D-Link DSL-526B
D-Link DSL-2640B
D-Link DSL-2740R
D-Link DSL-2780B
These are all combo DSL modem/routers, so if your DSL modem and router are different devices, or you use cable broadband instead of DSL, this warning doesn't apply.
