In Russia, technology company Yandex was met with the largest-documented DDoS attack.

With the increased cyber-attack count around the globe, businesses must know ways of handling the misuse of IPv4 addresses and IPv6 addresses.IP address misuse means the inappropriate use of a web server or IP address, including spam, malware, DDoS, hacking, phishing and other such attacks.

As per a recent survey, 81% of polled organizations were affected by at least one security breach in the past year.

An example is the consequences of a distributed denial-of-service attack that businesses encounter.

It could affect the value of your transactions in the IP market.When such misuse is not addressed, it would cause UCEProtect level 3, ‘Peer’ or ‘Don’t Route’ blacklists.

It is possible to protect servers with an SSH (secure socket shell) key.

Updated Just days into the new year, and poor old 123-Reg is already experiencing problems, this time in the form of a DDoS attack - something it is no stranger to.

Customers have been in touch with El Reg to report their websites and email services have been down as a consequence of the attack.

The outfit tweeted just over an hour ago: "We believe a DDoS attack has just started, we are working out remediation options and impact at present.

"Our networks team are continuing to scrub and reroute bad traffic.

Our teams are continuing to reroute traffic.

A further update on this work will be provided very shortly."

But for the gaming companies, suffering a DDoS attack is a disaster with immediate loss of revenue, mitigation costs and long-term consequences for their brand.

Global gaming companies build excitement with big, heavily-marketed release dates.

Being able to surgically shutting down the attacks without disrupting service is critical.

Growing the player base is essential for having a healthy game launch, especially in the highly competitive gaming industry.

So losing customers due to an inaccessible service or bad PR can have serious consequences for any game — just look at Diablo 3, which took years to recover from its self-inflicted “Error 37” fiasco.

Gaming companies generally operate worldwide, serving millions of users.

You can't possibly have failed to notice that the world has gone Pokémon Go crazy, and wherever there are folks trying to enjoy a new game, there will be people attempting to mess with that fun – and one way to do that is to bring down the Pokémon Go servers with a DDoS distributed denial of service attack.

Yes, the bad guys opened fire this weekend just gone, hitting the game's servers and causing users in the UK and the US to be unable to log on – which as you can imagine, didn't go down well with Pokémon Go addicts.

A group called PoodleCorp a hacktivist collective with a much fluffier name than Lizard Squad claimed it was their DDoS work which caused the outage.

As the Independent reports, on Saturday PoodleCorp tweeted: "PokemonGo Offline PoodleCorp", followed by a comment to the effect that bigger things were in the works: "Just was a lil test, we will do something on a larger scale soon."

Of course, whether or not the group actually caused the outage is another question, as that hasn't been verified.

But it seems that PoodleCorp is certainly serious enough about staging a bigger assault on the game, and this will happen at the start of next month according to the group's most recent tweet, which read: "August 1st PoodleCorp PokemonGo."

A group called New World Hackers has claimed responsibility for a DDoS attack that rendered significant portions of the web unreachable last Friday.

A series of assaults carefully targeted at managed DNS provider Dyn knocked the service offline for much of the day, causing disruption to multiple well-known sites that relied on its services including GitHub, Twitter, Reddit, Netflix, AirBnb and more.

Much of the attack traffic came Internet-of-Things devices compromised by the Mirai botnet malware.

Source code for the malware leaked online last month, allowing relatively unskilled cybercriminals to use PVRs, routers and more as a platform to launch denial of service attacks.

New World Hackers, a previously known group, claimed credit for the assault, which they said had been a "capability test".

The same group briefly knocked the BBC offline last year.

The failure of the Australian census seems to be a failure of planning.

The Federal Government is blaming a distributed denial of service attack DDoS and an abundance of caution for sending the once-every-five-years Antipodean citizen survey into a grinding halt beginning last night and continuing as of the time of writing.

Yet your correspondent would hazard should the question of 'what will bring down the Census' be asked on Family Feud, the top scoring answer would be a DDoS attack.

So how is it that the world's most boring attack vector was able to crush a multi-million dollar Federal Government operation some five years in the planning?

That does not mean the attack did not happen, or that apparent woeful internal technical failures were solely to blame, and the Government has lied about the cause of the outage.

Skeeve Stevens, founder of peering provider eintellego Networks, is one of many in the telco community who has not seen evidence of a large flood capable of taking down Census assets.

A political fact-checking site has been hacked almost immediately after it was endorsed by Hillary Clinton.

Clinton invited followers to sign up to Verrit on Sunday, but within an hour of her tweet a distributed denial of service (DDoS) attack prevented the site from loading.

It's now up and running again.

The site is aimed at "the 65.8 million", a reference to the higher number of US voters who picked Clinton in last year's Presidential Election over the eventual winner Donald Trump.

Verrit describes itself as a source of political information and analysis that "collects and contextualizes noteworthy facts, stats, and quotes for politically engaged citizens".

Political factchecking has become a hot topic amid the rise of "fake news", which refers to sources making up false news stories and spreading conspiracy theories.

In recent years, distributed denial-of-service DDoS attacks have become increasingly prevalent across the internet.

These techniques use a barrage of data to overwhelm a site s servers and render it inaccessible to ordinary users — and now there s evidence that an unknown entity is preparing to level this kind of assault against key web infrastructure.

Some of the companies that help keep the web up and running have reported an increase in DDoS attempts against their services in recent months, according to a report from Bruce Schneier.

The security expert suggests that these attacks could be part of a probing process intended to figure out what their targets can and cannot withstand.

The victims have apparently been forced to demonstrate their defense capabilities for the attacker, as the unknown originator of these probes has been steadily increasing its level of attack over a period of time.

The theory is that the attacks are intended to hone in on the exact point where a service s defenses fail.

In October 2016, DNS provider Dyn Inc. suffered a serious DDoS attack, which impacted a number of services including Airbnb, Paypal and Twitter.

Below, 10 members share their plans for thwarting future DDoS incidents:

DDoS attacks are difficult, as they are typically focused on overloading entry points.

Architect the overall solution to protect against the loss of service at every point within the architecture, then routinely physically test the production environments for possible threats.

Hackers try to exploit the most reliably available pathway to information there is: human laziness.

Although total victory over hackers may be impossible, we can combat their efforts via a balanced approach that focuses as much on mitigating exploits as on preventing them.

Denial of service attacks present a major threat to the world, but we may be set to see it get much worse as IoT devices continue to flood the consumer market.

Whether permanent or temporary disruption is caused by the attack, denial of service is when a hacker forces an internet-connected host to be unable to function.

This bombardment ultimately incapacitates the victim, left unable to barricade itself against the multitude of entry points, with customers or users of the target’s services also prevented from gaining access.

Now that these basics have been established, just a pure brute force approach to drowning the target with traffic remains, but this step is not always quite that simple.

Making complex DNS queries at an extremely high rate could be enough to make weaker systems suffer and fall into the hands of your attack, but many targets will be able to stand up to this simplistic method.

In this sense, a zombie is a device enslaved by a hacker to be used as part of the attack, a single device is not enough to generate a sizeable enough attack on its own to cause a denial of service.

Cloud hosting outfit Linode has again come under significant denial of service DoS attack.

The attacks aren't as bad as the epic events that all-but-took Linode down in January 2016, but they are coming in thick and fast.

The company's reported DoS attacks on September 2nd, September 4th and then a series of attacks on September 5th.

Another round struck on Saturday, September 10th.

Some of the attacks lasted up to eight hours.

Linode's engineers appear to have successfully fought off all of the attacks, but has often warned of degraded performance to APIs or sometimes to whole data centres.

The number of distributed denial of service attacks has doubled over the last 12 months.

Akamai reports that Q2 saw a 129 per cent year-on-year increase in total DDoS attacks.

During the second quarter, Akamai mitigated a total of 4,919 attacks, one of which against a media company reached an eye-watering 363n Gbps.

Although 10 attacks topped out at over 100 Gbps, the median rate of attack actually fell to an average of 3.85 Gbps.

NTP reflection attacks - a type of attack that relies on using insecure network time protocol servers to increase attack volumes - almost quadrupled, increasing 276 per cent over the same time frame.

The gaming and software industries remain the most frequently targeted industries for DDoS attacks over the last two quarters, the latest edition of Akamai s State of the Internet Security Report download link here, registration required concludes.

The success of the Mirai botnet was apparently a shiver looking for a spine to run up: HackForums has killed off its server stress test DDoS-for-hire section.

Site admin Jesse LaBrocca posted the decision last Friday here for registered members of the site , saying recent events forced the decision.

Brian Krebs quotes LaBrocca's post as saying I m personally disappointed that this is the path I have to take in order to protect the community.

I loathe having to censor material that could be beneficial to members.

But I need to make sure that we continue to exist and given the recent events I think it s more important that the section be permanently shut down.

The code first emerged being passed around the forums, until it was leaked to GitHub at the end of September.

But can you make your security function entirely an in-house affair?

It would be unwise to believe that you can do absolutely everything without looking to third parties for assistance or facilities.

DDoS is a genuine and significant threat, particularly with the marked ramp-up in Internet speeds available to the average home in recent months and years.

(Ookla just measured my home upload speed at 93.52MbPs, for example – you don’t need too many of those to whack someone with a DDoS attack.)

If you’re lucky (relatively speaking), it’ll overload one of your internet-facing servers and render it unavailable.

If you’re unlucky it’ll eat up all the bandwidth on your internet connection and render your entire installation unavailable.

Following the recent massive DDoS attacks powered by botnets which have hit the headlines, we ve had another warning about the amount of potentially vulnerable devices out there which could be compromised and used in such assaults – and the worrying scale these numbers might reach in the future, unless we take action.

Security firm BullGuard scanned in excess of 100,000 IPs hunting for such vulnerable IoT devices including the likes of security cameras, DVRs, routers and so forth , and managed a hit rate of 4.6%.

The company applied that to an estimate of the 4 billion connected devices currently out there, to work out a rough number of 185 million vulnerable devices which could be leveraged in Mirai-style botnet attacks.

Of course, the really worrying thing is when you extrapolate this using the typical figures expected for IoT gadget growth by the end of the decade – with analyst firms reckoning some 50 billion devices will be in play.

That would mean something like 920 million vulnerable pieces of hardware, almost a billion-strong army of potential DDoS cannon fodder.

As Paul Lipman, chief executive at BullGuard, observed, people need to ensure that basic security measures are in place with their devices, the main consideration in this case being that they must not be left on their default username and password settings which is how these things are so easily hacked en masse .

Major popular websites were inaccessible on Wednesday afternoon raising fears of another cyber attack.

Publishing websites including Reddit, the New York Times, CNN, ProPublica, and BuzzFeed were all affected by the issue, which was caused by a flaw in a network management system.

Visitors to affected sites were met with an error message that said, "Error 503: Maximum threads for service reached".

The problem persisted for around half an hour before Fastly, a company that serves the impacted sites, realised it was experiencing a "global event".

"Fastly is reporting a global event on our network at this time; mutltiple teams are responding and investigating," said Fastly.

Fifteen minutes after this initial message, it said, "A fix has been implemented and we are monitoring results."
