FireEye researchers recently found that many more cyber attacks occur during the middle of the week than on the weekends. "It seems these attackers don’t like to work on weekends, either," FireEye senior staff scientist Darien Kindlund wrote in a blog post.

"Like the typical office worker, the output of email attackers drops well below the average on Saturday and Sunday, picks up pace on Monday and then peaks on Wednesday," writes CSO Online's Liam Tung.

"Data from Q1 this year suggests that attackers enjoy working in the middle of the week, with the number of attacks on Wednesday and Thursday accounting for more than four times the average of usual attacks," writes Threatpost's Christopher Brook. "In fact, metrics gathered on alternating Wednesdays and Thursdays, Feb. 1, Feb. 9, March 7, and April 12, showed 473 percent, 444 percent, 385 percent and 387 percent increases in attacks, respectively."

"Meanwhile, attacks on Saturdays and Sundays barely scrape a third of the average, and the figure is consistently dropping," writes Gizmodo's Jamie Condliffe. "While it's only a small cross-section of hacking activity and there will always be exceptions to the rule, it's a reminder that, behind that screen, hackers are real people, too."
