Mac Developer: New leak may show if you were hacked by the NSA | Ars Technica

New leak may show if you were hacked by the NSA | Ars Technica: "Shadow Brokers—the name used by a person or group that created seismic waves in August when it published some of the National Security Agency's most elite hacking tools—is back with a new leak that the group says reveals hundreds of organizations targeted by the NSA over more than a decade."

Tax dollars hard at work.

Mac Developer: Lad cuffed after iOS call exploit knocks out Arizona 911 center • The Register

Lad cuffed after iOS call exploit knocks out Arizona 911 center • The Register: "The flood of calls from smartphones and tablets was eventually traced to Desai's personal site hosted in San Francisco, California; the cops managed to get the plug pulled on the site. The teen was arrested, taken to jail, and booked on three charges of computer tampering. A search warrant was also carried out at his home."

If only cybercrime laws were uniformly applied to Hilary Clinton.

Mac Developer: How security flaws work: SQL injection | Ars Technica

How security flaws work: SQL injection | Ars TechnicaThe earliest description of these attacks probably came in 1998, when security researcher Jeff Forristal, writing under the name "rain.forest.puppy," wrote about various features of Microsoft's IIS 3 and 4 Web servers in the hacker publication Phrack.
Terrific article about an important subject.

Mac Developer: AMD reveals Radeon Pro 400 series GPU specs, as used in new MacBook Pro | Ars Technica

AMD reveals Radeon Pro 400 series GPU specs, as used in new MacBook Pro | Ars TechnicaAMD has released a smattering of specs for the Radeon Pro 400 series on its Creators with Radeon Pro website, which show the Radeon Pro 450 used in the MacBook Pro to have a peak FP32 performance of around one teraflop. That's under half the 2.2 teraflops of the desktop-based RX 460 and miles behind the performance of Nvidia's Pascal-based laptop GPUs.
I liked the two GPU design that switched between the low-power Intel integrated graphics and the NVidia GPU as necessary.

Mac Developer: How Google's Project Zero made Apple refactor its kernel • The Register

How Google's Project Zero made Apple refactor its kernel • The Register: "It took eight months, apparently, because of a basic architectural feature of the kernel: calling target functions directly instead of via the MIG IPC (Mach interface generator inter process communication) layer is fast, but “there’s no central point where access to a resource can be cut off”."

That pesky monolithic kernel is longing for the microkernel promised land. QNX forever!

Yet ultimately, the data was safer with him than it would've been with Hilary or anyone else connected with the DNC.

Double-dip Internet-of-Things botnet attack felt across the Internet | Ars Technica: "The distributed denial of service attacks against dynamic domain name service provider Dyn this morning have now resurged. The attacks have caused outages at services across the Internet.

But this second wave of attacks appears to be affecting even more providers. According to Dale Drew, the chief security officer at Level 3 Communications, the attack is at least in part being mounted from a "botnet" of Internet-of-Things (IoT) devices."

More as the story develops...

Acronis: Yep, we're using blockchain for backup now • The Register: "Acronis was reported as checking out Blockchain technology in May. It says Notary generates a time-stamped hash, or fingerprint, of protected data and stores it in digital currency house Ethereum, a public blockchain-based distributed computing platform. By comparing two fingerprints of the same data, Acronis Storage is able to verify immutability, authenticity, and integrity of stored data. Regrettably Ethereum suffered a hack in June, illustrating it's not that secure."

US internet users suffering under DDoS attacks on key DNS provider: "Starting early Friday, assailants started a massive distributed denial of service (DDoS) attack on DNS provider Dyn's servers. Major sites like The Verge, HBO Now, CNN, Imgur, Paypal, and Reddit are all affected to some extent."

Mac Developer: “Most serious” Linux privilege-escalation bug ever is under active exploit (updated) | Ars Technica

“Most serious” Linux privilege-escalation bug ever is under active exploit (updated) | Ars Technica: "The vulnerability, a variety known as a race condition, was found in the way Linux memory handles a duplication technique called copy on write. Untrusted users can exploit it to gain highly privileged write-access rights to memory mappings that would normally be read-only"

Despite the collaborative nature of the kernel source base, the vulnerability is ubiquitous.

Mac Developer: Microsoft Surface sales boom amid tepid iPad demand

Microsoft Surface sales boom amid tepid iPad demand: "According to Microsoft's official numbers, Surface revenue came in at $926 million, up 38 percent compared to the same time last year. The surge for the quarter ending in September was largely due to a positive mix of premium devices sold, specifically top-tier Surface Book and Surface Pro 4 models."

Corporate IT developers like Windows because custom apps don't break on every new release of the OS. At least that's one idea.
