A Deep Dive Into DNS Packet Sizes: Why Smaller Packet Sizes Keep The Internet Safe

Yesterday we wrote about the 400 gigabit per second attacks we see on our network.

One way that attackers DDoS websites is by repeatedly doing DNS lookups that have small queries, but large answers. The attackers spoof their IP address so that the DNS answers are sent to the server they are attacking, this is called a reflection attack.

Domains with DNSSEC, because of the size of some responses, are usually ripe for this type of abuse, and many DNS providers struggle to combat DNSSEC-based DDoS attacks. Just last month, Akamai published a report on attacks using DNS lookups against their DNSSEC-signed .gov domains to DDoS other domains. They say they have seen 400 of these attacks since November.

To prevent any domain on CloudFlare being abused for a DNS amplification attack in this way, we took precautions to make sure most DNS answers we send fit in a 512 byte UDP packet, even when the zone is signed with DNSSEC. To do this, we had to be creative in our DNSSEC implementation. We chose a rarely-used-for-DNSSEC signature algorithm and even deprecated a DNS record type along the way.

Relatives of victims, law enforcement groups support FBI in iPhone unlocking case

Law enforcement groups and family members of victims of December's San Bernardino mass shooting have backed the FBI and opposed Apple in the court fight over an iPhone used by one of the shooters.Family members of the shooting victims "seek to remind all parties of the terrible crime -- an act of terrorism -- the United States must investigate to its fullest," wrote lawyers for family members of five victims and one witness to the shooting. "Ultimately, this is a situation where no stone can be left unturned."Much of the debate over the FBI's demands of Apple assistance has focused on the "potentially global ramifications" of Magistrate Judge Sheri Pym's Feb. 16 order requiring Apple to comply, but there's a law enforcement investigation to consider, the lawyers added.To read this article in full or to leave a comment, please click here

PlexxiPulse—Case Study: Perseus

If you’ve been following us on the blog or social media, you know that we announced a partnership with Perseus last week to help expand their global reach into 29 sites across the globe. Perseus has built the world’s largest SDN-based on demand services network, allowing them to quickly offer new products and services while enabling new deployments at a rapid pace. They needed a vendor that could offer the agility and flexibility to deliver services very rapidly and cross the globe, controlling the speed of execution, delivery and operating expenses. Light Reading reporter Mitch Wagner explored the partnership in detail last week and our CEO Rich Napolitano penned a case study on the Plexxi blog as well. Both pieces illustrate how Plexxi is helping to build (and scale) next-generation networks of tomorrow.

InfoWorld: What hyperscale storage really means
By Rob Whiteley
Let’s be clear: Hyperscale isn’t about how large you are. Organizations don’t have to be huge to leverage hyperscale solutions. But that’s exactly what many IT infrastructure, operations, and devops pros think when they first learn about hyperscale. The Continue reading

‘Serious risk’ that Apple-made iPhone cracking code will leak

Security experts yesterday said that there is a "serious risk" that the special iPhone-cracking software sought by the FBI would fall into the wrong hands if Apple is forced to assist the government in accessing the data on an iPhone used by one of the San Bernardino shooters."Keeping the Custom Code secret is essential to ensuring that this forensic software not pose a broader security threat to iOS users," seven security experts said Thursday in a "friends-of-the-court" brief filed with a California federal court. "But the high demand [for this software] poses a serious risk that the Custom Code will leak outside of Apple's facilities."+ ALSO ON NETWORK WORLD Apple v.

Five things you need to know about ransomware

Over the past few years millions of PCs from around the world have been locked or had their files encrypted by malicious programs designed to extort money from users. Collectively known as ransomware, these malicious applications have become a real scourge for consumers, businesses and even government institutions. Unfortunately, there's no end in sight, so here's what you should know.It's not just your PC that's at riskMost ransomware programs target computers running Windows, as it's the most popular operating system. However, ransomware applications for Android have also been around for a while and recently, several variants that infect Linux servers have been discovered.To read this article in full or to leave a comment, please click here

Cerber ransomware sold as a service, speaks to victims

A new file-encrypting ransomware program called Cerber has taken creepiness for victims, but also affordability for criminals, to a new level.In terms of functionality Cerber is not very different than other ransomware threats. It encrypts files with the strong AES-256 algorithm and targets dozens of file types, including documents, pictures, audio files, videos, archives and backups.The program encrypts file contents and file names and changes the original extensions to .cerber. It can also scan for and encrypt available network shares even if they are not mapped to a drive letter in the computer.Once the encryption process is done, Cerber will drop three files on the victim's desktop named "# DECRYPT MY FILES #." They contain the ransom demand and instructions on how to pay it. One of those files is in TXT format, one is HTML and the third contains a VBS (Visual Basic Scripting).To read this article in full or to leave a comment, please click here

UN human rights chief warns of worldwide privacy implications of Apple-FBI case

A ruling ordering Apple to help the FBI access the iPhone of San Bernardino mass shooter Syed Rizwan Farook could make it impossible for the company or any other major international IT vendor to safeguard users' privacy anywhere in the world, U.N. High Commissioner for Human Rights Zeid Ra’ad Al Hussein said Friday.A decision against Apple would be "potentially a gift to authoritarian regimes, as well as to criminal hackers,” Zeid said. Authorities in other countries have already made efforts to force IT and communications companies such as Google and BlackBerry to expose their customers to mass surveillance, he added.Zeid's statement is a shot in the arm for Apple's appeal in the case. A magistrate judge in the U.S. District Court for the Central District of California, Eastern Division, has ordered Apple to provide technical assistance, including possibly signed software, to help the FBI use brute force to crack the passcode of the iPhone 5c used by Farook  in the San Bernardino, California, attack on Dec. 2, without triggering an auto-erase feature.To read this article in full or to leave a comment, please click here
