DDoS Attacks: Case of the Tuesdays


Hundreds of unread e-mails, queue of meetings after meetings and an ever-expanding list of things to do. All you want to do is leave work and go back to bed. “Uh-oh, sounds like somebody’s got a case of the Mondays.”

However, for cybersecurity professionals that fought off Distributed Denial of Service (DDoS) attacks during the second quarter of 2016, Mondays were the second worst day of the week. According to a recent report by Kaspersky Lab, Tuesday was the most active day of the week for DDoS attacks—15.2 percent of the attacks occurred on Tuesdays—followed by Monday and Thursday. It looks like even cybercriminals need to take a day off, as Sunday was the quietest day of the week for DDoS attacks, the report said.

DDoS attack is a type of a denial of service (DoS) attack that seeks to make a network unavailable for its intended users by overloading the target network or machine with unnecessary requests. DDoS is where the DoS attack source is made up of multiple unique internet protocol addresses.

According to the Kaspersky report, resources in 70 countries were targeted by DDoS attacks in Q2 2016, with more than 77 percent of the targeted resources being located in China. Following China, the most targeted countries were South Korea and the U.S.

DDoS attack is a serious problem. In 2014, Sony’s PlayStation Network and the Sony Entertainment Network were taken down by a plain old DDoS attack. The Kaspersky report said that DDoS attacks of cryptocurrency wallet service providers caused two companies—CoinWallet and Coikite—to close shop.
