CloudFlare Supports the Passage of the USA Freedom Act

alt

Earlier today, the lower house in the U.S. Congress (the House of Representatives) passed the USA FREEDOM Act. The Act, if passed by the Senate and signed by the President, would seek to sunset the National Security Agency’s bulk collection and mass surveillance programs, which may or may not be authorized by Section 215 of the PATRIOT Act. Under this authority the U.S. government has established its broad surveillance programs to indiscriminately collect information. Other governments have followed this lead to create additional surveillance capabilities—most recently, the French Parliament has moved a bill that would allow broad surveillance powers with little judicial oversight.

Restricting routine bulk collection is important: it’s not the government’s job to collect everything that passes over the Internet. The new version of the USA FREEDOM Act keeps useful authorities but ends bulk collection of private data under the PATRIOT Act. It also increases the transparency of the secret FISA court, which reviews surveillance programs—a key start to understanding and fixing broken policies around surveillance. The Act would also allow companies to be more transparent in their reporting related to FISA orders.

To be clear, we continue to be supportive of law enforcement and work Continue reading

House votes to narrow NSA’s phone records collection

The U.S. House of Representatives has voted to rein in the National Security Agency’s bulk collection of the country’s telephone records, while allowing the agency to engage in more targeted surveillance.The House voted 338-88 late Wednesday to approve the USA Freedom Act, a bill intended to end the NSA’s mass collection of telephone metadata within the U.S. But the bill would extend an expiring provision in the anti-terrorism Patriot Act that allows the NSA to collect U.S. telephone and business records, but with a more limited scope.To read this article in full or to leave a comment, please click here

NSA: ad hominem is stil a fallacy

An ad hominem attack is where, instead of refuting a person's arguments, you attack their character. It's a fallacy that enlightened people avoid. I point this out because of a The Intercept piece about how some of NSA's defenders have financial ties to the NSA. This is a fallacy.


The first rule of NSA club is don't talk about NSA club. The intelligence community frequently publishes rules to this effect to all their employees, contractors, and anybody else under their thumb. They don't want their people talking about the NSA, even in defense. Their preferred defense is lobbying politicians privately in back rooms. They hate having things out in the public. Or, when they do want something public, they want to control the messaging (they are control freaks). They don't want their supporters muddying the waters with conflicting messaging, even if it is all positive. What they fear most is bad supporters, the type that does more harm than good. Inevitably, some defender of the NSA is going to say "ragheads must die", and that'll be the one thing attackers will cherry pick to smear the NSA's reputation.

Thus, you can tell how close somebody is to the NSA by Continue reading

HP’s PC group cranks up design, gaming efforts ahead of spin-off

HP’s PC group doesn’t want to be a “screwdriver” PC maker making look-alike laptops and desktops, and it is focusing heavily on design and new innovations as it prepares for a spin-off into a separate company.The company is focusing on cutting the plastic and adding metal and new colors to the chassis of its laptops and desktops. HP also is expanding its hardware options for consumers, businesses and gamers, and focusing on a future when virtual reality will be an important part of the computing experience.PC makers need to update the devices because customers are paying more attention to how devices look and function, said Mike Nash, vice president for consumer PC and solutions at HP’s Printing and Personal Systems Group.To read this article in full or to leave a comment, please click here

How China’s smartphone market is evolving

The Chinese mobile market has long been described as the ultimate prize for smartphone handset makers and app developers. China has the most people, income is rising, and the population has an insatiable appetite for mobile technology.That's all true, except when the facts don't quite support the narrative.For example, the conventional wisdom holds that most Chinese mobile consumers are interested in inexpensive phones from upstart manufacturers like Xiaomi, Huawei, and ZTE. And that's true, up to a point. According to IDC's latest Mobile Phone Tracker, many of those brands are trying to move up into the mid- and high-end segments.To read this article in full or to leave a comment, please click here

Some brief technical notes on Venom

Like you, I was displeased by the lack of details on the "Venom" vulnerability, so I thought I'd write up what little I found.

The patch to the source code is here. Since the note references CVE-2015-3456, we know it's venom:
http://git.qemu.org/?p=qemu.git;a=commit;h=e907746266721f305d67bc0718795fedee2e824c

Looking up those terms, I find writeups, such as this one from RedHat:
https://securityblog.redhat.com/2015/05/13/venom-dont-get-bitten/

It comes down to a typical heap/stack buffer overflow (depending), where the attacker can write large amounts of data past the end of a buffer. Since this is the kernel, there are no protections like NX or ASLR. To exploit this, you'd likely need some knowledge of the host operating system.

The details look straightforward, which means a PoC should arrive by tomorrow.

This is a hypervisor privilege escalation bug. To exploit this, you'd sign up with one of the zillions of VPS providers and get a Linux instance. You'd then, likely, replace the floppy driver in the Linux kernel with a custom driver that exploits this bug. You have root access to your own kernel, of course, which you are going to escalate to root access of the hypervisor.

People suggest adding an exploit to toolkits like Continue reading

Critical VM escape vulnerability impacts business systems, data centers

A critical vulnerability in code used by several virtualization platforms can put business information stored in data centers at risk of compromise.The flaw, dubbed Venom but tracked as CVE-2015-3456, can allow an attacker to break out from the confines of a virtual machine (VM) and execute code on the host system.This security boundary is critical in protecting the confidentiality of data in data centers, where virtualization is extensively used to allow different tenants to run servers on the same physical hardware.The flaw is located in the virtual Floppy Disk Controller (FDC) code from the QEMU open source machine emulator and virtualizer. The code is also used by the Xen, KVM and other virtualization platforms.To read this article in full or to leave a comment, please click here

Establishing your virtual presence on the cheap

I was excited to see what Double Robotics has accomplished with their telepresence robot, especially when one showed up on an episode of The Good Wife. Double Robotics’ device (see http://www.doublerobotics.com/) is making it possible for teleworkers to have their “doubles” moving around the office, chatting with staff, and attending meetings. The devices works like an iPad on a Segway, though the stand/roller part of the setup is much lighter and slimmer than a Segway, so it’s more like an iPad on a rolling stick. But the movement is controlled remotely and the person controlling it has a sense from their screen of moving around the office and interacting with the staff because their “double” really is.To read this article in full or to leave a comment, please click here

Public Key Authentication on Cisco IOS

Have you ever been in that situation that you needed to apply the same configuration quickly on multiple Cisco routers? If yes, you probably wrote a script that connected to routers and sent appropriate IOS commands. One problem that you certainly had to solved was forcing your script to enter login credentials such as username and password. Moreover if you secure an access to privileged user mode of routers with an enable secret command you had to tell the script how to enter that password as well.

All the issues I have mentioned above can be easily solved with Expect scripting language. Expect sends commands via telnet or ssh session as the human would. However encapsulating IOS commands to syntax recognized by Expect language every time you need to change routers' configuration seems to be not very comfortable. That is why public key authentication for Cisco routers can be handy.

Public key authentication allows you to log in to your routers using  RSA key instead of a password. But firstly  key-pair - public and private key must be generated and a public key copied into a config file of  the router. Then you can connect to the router with your  private key. A private key is the key that should Continue reading
