According to recent statistics Kaspersky Lab for the first quarter of 2015, digital criminals made more than 23.000 attacks DDoS, which were supported by botnet (malicious networks) to online resources in 76 countries, including Greece. 
Most attacks on a unique online resource were 21 (about two attacks per week). In the fourth quarter of 2014, the corresponding size was 16. The longest-ever botnet attack during the first quarter lasted about six days.
In the first quarter of 2015, a total of 23.095 DDoS attacks occurred. These hit targets in 76 countries, a size higher than 15% over the 66 countries recorded in the fourth quarter of 2014.
China, the USA and Canada were the countries most affected by DDoS attacks in the first quarter. These attacks were controlled by Command & Control (C&C) servers which were mainly located in USA, China and UK.
The "leadership" positions of China and the US in both rankings can be explained by the relatively low prices for web hosting in these countries, which results in most data centers being there.
"A DDoS attack is often a cross-border effort. The client is in one country, the executor in another, the C&C servers are hosted in a third and the bots involved in the DDoS attack are scattered around the world. This often complicates investigating attacks, cracking down on botnets and arresting those responsible. "Although the tools of digital criminals for DDoS attacks are not limited to botnets, they are still a widespread and dangerous tool, which requires taking precautionary measures against potential targets to ensure their protection." commented Evgeny Vigovsky, Head of Kaspersky DDoS Protection Kaspersky Lab.
Η Kaspersky Lab recommends the use of security solutions to filter "unwanted" requests from digital criminals and separate them from legitimate online traffic.
For example, the Kaspersky DDoS Protection solution combines Kaspersky Lab's proven experience with in-house technology, such as DDoS Intelligence. DDoS Intelligence is a system that analyzes the information sent by C&C servers to botnets, with the aim of enhancing protection against DDoS attacks.
Kaspersky Lab's statistics for botnet activity in the first quarter of 2015 are based on data collected by the DDoS Intelligence system.
The full report with the statistics is available on the site Securelist.com. More information about Kaspersky DDoSProtection is available at site of Kaspersky Lab.
