Firefox 2.0: happier browsing, but secure?

Filed under

It's long past time to bother telling anyone how much better than IE Firefox is. Faster, smaller, more responsive, with tabbed browsing and useful extensions galore. It's also lot more secure than IE, partly because it's open source, and particularly because it's not integrated with the underlying OS. Firefox's security bugs involve the browser only.

Almost famous

Up until a few years ago, Linux was mainly used on servers. Now, it’s increasingly being used on desktop computers and notebook PCs. The Linux Counter Project estimates there are 29 million users, which would give it just about 3.6 percent of the total personal computer market worldwide. But a number of factors are likely to push these numbers higher.

What if Hardware Vendors are Trapped Too?

Filed under

Want some frustration? Buy a piece of hardware with “Linux support” and try to use it on anything besides x86 GNU/Linux. If you’re fortunate enough to choose a device for which there exists free drivers, you’ll have much more luck. What about the other vendors?

Fedora's metrics have ripple effect

Filed under

Fedora announced this month that by using a tracking tool to monitor unique IP addresses, it was able to determine that Fedora Core 6 now has more than one million users. What does all this metric gathering mean for future Fedora releases? Moreover, what does it mean for the Linux community at large? The answer on both counts: plenty.

Linux 4.8.4

I'm announcing the release of the 4.8.4 kernel. And yeah, sorry about the quicker releases, I'll be away tomorrow and as they seem to have passed all of the normal testing, I figured it would be better to get them out earlier instead of later. And I like releasing stuff on this date every year... All users of the 4.8 kernel series must upgrade. The updated 4.8.y git tree can be found at: git:// linux-4.8.y and can be browsed at the normal git web browser: Read more Also: Linux 4.7.10 Linux 4.4.27

Security News

  • Free tool protects PCs from master boot record attacks [Ed: UEFI has repeatedly been found to be both a detriment to security and enabler of Microsoft lock-in]
    Cisco's Talos team has developed an open-source tool that can protect the master boot record of Windows computers from modification by ransomware and other malicious attacks. The tool, called MBRFilter, functions as a signed system driver and puts the disk's sector 0 into a read-only state. It is available for both 32-bit and 64-bit Windows versions and its source code has been published on GitHub. The master boot record (MBR) consists of executable code that's stored in the first sector (sector 0) of a hard disk drive and launches the operating system's boot loader. The MBR also contains information about the disk's partitions and their file systems. Since the MBR code is executed before the OS itself, it can be abused by malware programs to increase their persistence and gain a head start before antivirus programs. Malware programs that infect the MBR to hide from antivirus programs have historically been known as bootkits -- boot-level rootkits. Microsoft attempted to solve the bootkit problem by implementing cryptographic verification of the bootloader in Windows 8 and later. This feature is known as Secure Boot and is based on the Unified Extensible Firmware Interface (UEFI) -- the modern BIOS.
  • DDOS Attack On Internet Infrastructure
    I hope somebody's paying attention. There's been another big DDOS attack, this time against the infrastructure of the Internet. It began at 7:10 a.m. EDT today against Dyn, a major DNS host, and was brought under control at 9:36 a.m. According to Gizmodo, which was the first to report the story, at least 40 sites were made unreachable to users on the US East Coast. Many of the sites affected are among the most trafficed on the web, and included CNN, Twitter, PayPal, Pinterest and Reddit to name a few. The developer community was also touched, as GitHub was also made unreachable. This event comes on the heels of a record breaking 620 Gbps DDOS attack about a month ago that brought down security expert Brian Krebs' website, KrebsonSecurity. In that attack, Krebs determined the attack had been launched by botnets that primarily utilized compromised IoT devices, and was seen by some as ushering in a new era of Internet security woes.
  • This Is Why Half the Internet Shut Down Today [Update: It’s Getting Worse]
    Twitter, Spotify and Reddit, and a huge swath of other websites were down or screwed up this morning. This was happening as hackers unleashed a large distributed denial of service (DDoS) attack on the servers of Dyn, a major DNS host. It’s probably safe to assume that the two situations are related.
  • Major DNS provider Dyn hit with DDoS attack
    Attacks against DNS provider Dyn continued into Friday afternoon. Shortly before noon, the company said it began "monitoring and mitigating a DDoS attack" against its Dyn Managed DNS infrastructure. The attack may also have impacted Managed DNS advanced service "with possible delays in monitoring."
  • What We Know About Friday’s Massive East Coast Internet Outage
    Friday morning is prime time for some casual news reading, tweeting, and general Internet browsing, but you may have had some trouble accessing your usual sites and services this morning and throughout the day, from Spotify and Reddit to the New York Times and even good ol’ For that, you can thank a distributed denial of service attack (DDoS) that took down a big chunk of the Internet for most of the Eastern seaboard. This morning’s attack started around 7 am ET and was aimed at Dyn, an Internet infrastructure company headquartered in New Hampshire. That first bout was resolved after about two hours; a second attack began just before noon. Dyn reported a third wave of attacks a little after 4 pm ET. In all cases, traffic to Dyn’s Internet directory servers throughout the US—primarily on the East Coast but later on the opposite end of the country as well—was stopped by a flood of malicious requests from tens of millions of IP addresses disrupting the system. Late in the day, Dyn described the events as a “very sophisticated and complex attack.” Still ongoing, the situation is a definite reminder of the fragility of the web, and the power of the forces that aim to disrupt it.
  • Either IoT will be secure or the internet will be crippled forever
    First things first a disclaimer. I neither like nor trust the National Security Agency (NSA). I believe them to be mainly engaged in economic spying for the corporate American empire. Glenn Greenwald has clearly proven that in his book No Place to Hide. At the NSA, profit and power come first and I have no fucking clue as to how high they prioritize national security. Having said that, the NSA should hack the Internet of (insecure) Things (IoT) to death. I know Homeland Security and the FBI are investigating where the DDoS of doomsday proportions is coming from and the commentariat is already screaming RUSSIA! But it is really no secret what is enabling this clusterfuck. It’s the Mirai botnet. If you buy a “smart camera” from the Chinese company Hangzhou XiongMai Technologies and do not change the default password, it will be part of a botnet five minutes after you connect it to the internet. We were promised a future where we would have flying cars but we’re living in a future where camera’s, light-bulbs, doorbells and fridges can get you in serious trouble because your home appliances are breaking the law.
  • IoT at the Network Edge
    Fog computing, also known as fog networking, is a decentralized computing infrastructure. Computing resources and application services are distributed in logical, efficient places at any points along the connection from the data source (endpoint) to the cloud. The concept is to process data locally and then use the network for communicating with other resources for further processing and analysis. Data could be sent to a data center or a cloud service. A worthwhile reference published by Cisco is the white paper, "Fog Computing and the Internet of Things: Extend the Cloud to Where the Things Are."
  • Canonical now offers live kernel patching for Ubuntu 16.04 LTS users

  • ​The Dirty Cow Linux bug: A silly name for a serious problem
    Dirty Cow is a silly name, but it's a serious Linux kernel problem. According to the Red Hat bug report, "a race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system."
