  • A New Ubuntu Kernel Build With The Very Latest AMDGPU DC Patches For 4.15

    This week the latest AMDGPU DC patches were queued up ahead of Linux 4.15. As covered in that article, those several dozen patches mostly further clean-up this major AMDGPU display code rework and trim it up by a few thousand lines of code. For those wishing to test out this new display stack, here is a fresh Ubutu/Debian x86_64 kernel build.

  • Facebook Developers Working On FSPERF For Better Linux File-System/Block Testing

    Josef Bacik of Facebook's file-system/storage team has announced fsperf as a new testing framework around the Linux file-system/block storage code.

    With every Linux file-system developer seeming to construct his own scripts and to test their file-system/block kernel code in a different manner, Josef is hoping fsperf can unify some of the processes by these Linux kernel developers.

  • SLIMbus Framework Revised For The Linux Kernel

    Linaro developers have restored work on the SLIMbus patches for the Linux kernel, which have long been dormant.

    SLIMbus is the Serial Low-power Inter-chip Media Bus, which is a standard from the MIPI alliance to allow multiple digital audio components to communicate simultaneously and carry multiple audio streams of differing sample rates and bit widths.

  • One-stop counterfeit certificate shops for all your malware-signing needs

    The Stuxnet worm that targeted Iran's nuclear program almost a decade ago was a watershed piece of malware for a variety of reasons. Chief among them, its use of cryptographic certificates belonging to legitimate companies to falsely vouch for the trustworthiness of the malware. Last year, we learned that fraudulently signed malware was more widespread than previously believed. On Thursday, researchers unveiled one possible reason: underground services that since 2011 have sold counterfeit signing credentials that are unique to each buyer.

  • Intel didn't give government advance notice on chip flaws

    Google researchers informed Intel of flaws in its chips in June. The company explained in its own letter to lawmakers that it left up to Intel informing the government of the flaws.

    Intel said that it did not notify the government at the time because it had “no indication of any exploitation by malicious actors,” and wanted to keep knowledge of the breach limited while it and other companies worked to patch the issue.

    The company let some Chinese technology companies know about the vulnerabilities, which government officials fear may mean the information was passed along to the Chinese government, according to The Wall Street Journal.

  • Intel hid CPU bugs info from govt 'until public disclosure'

    As iTWire reported recently, Intel faces a total of 33 lawsuits over the two flaws. Additionally, the Boston law firm of Block & Leviton is preparing a class action lawsuit against Intel chief executive Brian Krzanich for allegedly selling a vast majority of his Intel stock after the company was notified of the two security flaws and before they became public.

  • Intel did not tell U.S. cyber officials about chip flaws until made public [iophk: "yeah right"]

    Current and former U.S. government officials have raised concerns that the government was not informed of the flaws before they became public because the flaws potentially held national security implications. Intel said it did not think the flaws needed to be shared with U.S. authorities as hackers [sic] had not exploited the vulnerabilities.

  • LA Times serving cryptocurrency mining script [iophk: "JS"]

    The S3 bucket used by the LA Times is apparently world-writable and an ethical hacker [sic] appears to have left a warning in the repository, warning of possible misuse and asking the owner to secure the bucket.

  • Facebook's Mandatory Malware Scan Is an Intrusive Mess

    When an Oregon science fiction writer named Charity tried to log onto Facebook on February 11, she found herself completely locked out of her account. A message appeared saying she needed to download Facebook’s malware scanner if she wanted to get back in. Charity couldn’t use Facebook until she completed the scan, but the file the company provided was for a Windows device—Charity uses a Mac.

  • Tinder plugs flaw that enabled account takeover using just a phone number

    As Tinder uses Facebook profile pics for its users to lure in a mate or several, the 'dating' app is somewhat tied to the social network. When a swipe-hungry Tinder user comes to login to their account they can either do so via Facebook or use their mobile number.
