The Latest Intelligence page has been refreshed through January 2016, providing the most up-to-date analysis of cybersecurity threats, trends, and insights concerning malware, spam, and other potentially harmful business risks. Here are some key takeaways from this latest batch of intelligence.
In terms of social media, manually shared scams continued to dominate and made up nearly 56 percent of all social media scams. However, this number is down from 64.9 percent in December. The reason for the dip is a significant increase in the number of fake offers seen on social media in January, accounting for around 38.6 percent of social media scams. This number is up more than 11 percentage points from December.
