When a malicious user wants to disrupt web services, they often use a distributed denial of service (DDoS) attack. You’ve probably heard the phrase countless times in the media. The basic idea is always the same: send so much junk to a server that legitimate traffic cannot get through. DDoS has been used against root domain servers in a bid to shut down the entire world wide web. Despite being as old as the internet itself, DDOS is still one of the most effective tools malicious users have at their disposal. But what does a DDoS attack actually involve? We first have to understand both denial of service and distributed denial of service. What is a DDoS Attack ? The difference between DOS and DDOS is in the origin of the attack. A denial of service (DOS) attack comes from a single person or network. A distributed denial of service attack (DDOS) will involve computers from networks all over the world. (Distributing the attack amplifies it, and it also makes it more diffic...

First, consider increasing bandwidth and server performance.  DDoS attacks attempt to overwhelm available resources so additional resources will allow you to withstand greater attacks.  This involves having more server space or bandwidth than necessary.  Such over-provisioning addresses the number one problem brought on by a DDoS attack, link and equipment saturation.  Unfortunately, it can be difficult to determine how much extra hardware and bandwidth is necessary to sustain an attack as even some of the largest companies have succumbed to DDoS attacks.  When attacks fail, attackers often gather a larger bot army and try again. Traffic Filtering Consider configuring your firewall or IDS (Intrusion Detection System) to filter DDoS traffic, if the functionality is available, or consider upgrading to a system that does.  DDoS traffic filtering devices prevent SYN, TCP Flooding and other types of DDoS attacks.  Such devices typically analyze TCP flo...

OKEx and Bitfinex have suffered DDoS attacks in a short time frame. Distributed denial-of-service (DDoS) attacks are malicious attempts at disrupting normal traffic of targeted service and a major concern in internet security today. While being more effective at defending themselves and resolving the issues caused by DDoS attacks, tech giants are no exception and still face these threats. how does a ddos attack work ? OKEx, a top of the line cryptocurrency exchange and advanced financial service provider, made an announcement on Weibo, stating that they had been targeted for a DDoS attack last night. However, their support team was able to detect the attacks early on and resolve the issues rather quickly, assuring that no clients had been affected by the attack. While the exact source of the attack is unknown, OKEx believes it to be an attack orchestrated by a competitor. Jay Hao, CEO of OKEx, commented on the subject by saying that the products and technologies of their com...

DDoS attacks happen every day. Well-prepared organizations can repel an attack with few repercussions. Poorly-prepared organizations sustain the attack, often to their detriment. They experience downtime, lost business, and customer loss of confidence, and they might even be subjected to ransom demands. Lately there has been a rash of attacks where the perpetrators have demanded a ransom paid in Bitcoins in order to avoid or stop the attack. how to report a ddos attack ? Whatever the circumstances, many attacks have one thing in common: the victim organization rarely reports the crime to law enforcement if they don't “have to.” The reasons for no report range from not wanting to garner the attention that an investigation would bring, to the belief that the attackers will never be brought to justice anyway, so why bother? Of course, some attacks are so high profile that law enforcement feels compelled to get involved. Fortunately for everyone, the “lack of justice” excuse is ...

Don’t let the DDoS attack interrupt your business operation for reputational and financial loss. Use cloud-based denial of service protection to prevent getting hacked. Denial-of-service attack definition Anyone with bad intentions can hire a hacking service for a targeted attack. Malware tools are accessible, easy to use, and effective. Not just large companies, but cybercriminals are looking for any size vulnerable victims, including personal blogs, e-commerce shops, small to medium businesses. One type of attack is particularly dangerous and increasingly common. It is called distributed denial of service attack, or DDoS for short. In a DDoS attack, a set of compromised, distributed systems –could be servers, home computers, Internet-of-Things devices, anything connected to the internet– is used to overwhelm a targeted system with a flood of requests, to the point in which the attacked system gets saturated enough to refuse to work. Since the flood comes from many scattered...
