Security Password Managers, Updates, Intel/Linux, 5 Antivirus for Android Devices and Cisco

Your Password Manager Has A Severe Flaw — But You Should Still Use One [Ed: Yet worse: 1) people putting password managers on platforms with back doors from Apple and Microsoft. 2) people putting all their password "in the cloud".]
If you are an avid user of password managers, you might just be in for a surprise. A recent study by researchers at the Independent Security Evaluators found that a number of popular password managers were storing master passwords as plain text within the main memory of devices.
To an expert hacker, this vulnerability is equivalent to getting the keys to multiple accounts as a text document on your computer. The master key of any password manager can be used to gain access to all usernames and passwords being managed by it.

Fun Little Tidbits in a Howling Storm (Re: Intel Security Holes)
Some kernel developers recently have been trying to work around the massive, horrifying, long-term security holes that have recently been discovered in Intel hardware. In the course of doing so, there were some interesting comments about coding practices.
Christoph Hellwig and Jesper Dangaard Brouer were working on mitigating some of the giant speed sacrifices needed to avoid Intel's gaping security holes. And, Christoph said that one such patch would increase the networking throughput from 7.5 million packets per second to 9.5 million—a 25% speedup.
To do this, the patch would check the kernel's "fast path" for any instances of dma_direct_ops and replace them with a simple direct call.
Linus Torvalds liked the code, but he noticed that Jesper and Christoph's code sometimes would perform certain tests before testing the fast path. But if the kernel actually were taking the fast path, those tests would not be needed. Linus said, "you made the fast case unnecessarily slow."

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
