The Future of Cloud Technology

Distributed denial-of-service (DDoS) attacks have become more common, more powerful, and more useful to attackers. Here's how to fight back. On the flip side of the proliferation of Internet of Things (IoT) devices, the quest for increased connectivity and bandwidth (think 5G) and skyrocketing cloud adoption, IT is increasingly being weaponized to unleash cyberattacks in an unprecedented order of magnitude. Coupled with the emergence and anonymous nature of both the Dark Web and cryptocurrencies, illicit transactions have never been easier or more convenient. Distributed denial-of-service (DDoS) attacks have become more common, more powerful, and more useful to attackers. They have advanced from mere botnet-based approaches to artificial intelligence (AI) and data-driven models. Know more about the  online ddos attack ? Scholars at the University of Cambridge last year published a research note describing how they used data science to shed light on criminal pathways and ferr...

The simple approach to DOS is to flood a server with a large amount of pointless traffic. This gives the server far too much to deal with. Bandwidth escalates, memory is exhausted and ordinary users can’t get a connection to the server. DDoS stands for But actually maxing out a server can be quite difficult, even with a large number of computers opening up as many connections as they can. As such, attackers have come up with a way to magnify the effect by using fake IP addresses. Using fake IPs, the same process can be carried out by one computer, a botnet that’s controlled by one master or, as with Operation Payback, a group of people working together. Here’s what happens. The attacking machine sends a SYN packet to the server. However, it makes it appear to come from somewhere else. The server then responds with a SYN/ACK packet, but there’s no response – the sender address was fake. The server continues to wait for a reply, keeping the connection open and in its memory...

Distributed denial of service attacks (DDoS) are “significantly” on the rise, suggest a new report from F5 Labs. The same report also argues brute force attacks, although still present, are losing steam. In the past two years, DDoS attacks accounted for almost half (49 percent) of all cyberattacks, representing “by far the biggest threat” to organisations worldwide. DDoS attack definition This past year was particularly tough on businesses, the report states, with attacks rising by more than three quarters (77 percent). Brute force attacks, on the other hand, are on the decline. Responsible for 72 percent of all attacks in 2017, this attack type accounted for just 20 percent of all attacks last year. “In general, service providers have made important strides to defend their networks, but there is still room for improvement," said Malcolm Heath, Senior Threat Research Evangelist, F5 Labs. "This is particularly true when it comes to detecting attacks early without ...

In a world dominated by the digital world, everything seems to be just a click away. Our dependence on digital media has grown manifolds in the past couple of decades. But this dependency has also given birth to many notorious activities, and one of such activity is DDos attack. What is a DDoS attack ? DDoS attack or distributed denial of service attack is making it impossible to deliver the service to its end customers. In this kind of attack access to almost everything including s devices, servers, applications, services, networks, etc. is prevented. The difference between DoS attack and DDoS attack is that in DoS attack malicious data or requests are sent from one system whereas in a DDoS attack it can be sent from multiple systems. Multiple requests for data are masked to the system to initiate this attack. It could be done by either extensive request to the webserver to serve a page so that it ultimately crashes because of high demand. The other way is to a large number o...

Hacking attacks against crypto exchanges have become fairly common, and not a lot of people are surprised when they hear about them at this point. With that said, attacks on major exchanges are still very important events, and the two exchanges attacked in the last 24 hours are both quite well-known. According to recent reports, Malta-based OKEx was attacked twice, with the first attack taking place yesterday, and the second one targeting exchange again today. The attacks were disclosed by the exchange’s own CEO, Jay Hao, who reported them on his Weibo account. what are ddos attacks ? According to the announcement, the first attack had a severity of 200 GB, while the second one ended up being twice as strong, with 400GB severity. Despite the two attacks, the company’s CEO claims that the exchange remains largely unaffected. OKEx did not disclose the attacks on Twitter, but it did hint that a system upgrade for futures and options trading is to take place. Bitfinex had to brief...
