[$] BPF meets io_uring
Over the last couple of years, a lot of development effort has gone into two kernel subsystems: BPF and io_uring. The BPF virtual machine allows programs from user space to be safely run within the context of the kernel, while io_uring addresses the longstanding problem of running system calls asynchronously. As the two subsystems expand, it was inevitable t […]

A warning about 5.12-rc1
Linus Torvalds has sent out a note telling people not to install the recent 5.12-rc1 development kernel; this is especially true for anybody running with swap files. "But I want everybody to be aware of because _if_ it bites you, it bites you hard, and you can end up with a filesystem that is essentially overwritten by random swap data. This is what we […]

[$] Alternative syntax for Python's lambda
The Python lambda keyword, which can be used to create small, anonymous functions, comes from the world of functional programming, but is perhaps not the most beloved of Python features. In part, that may be because it is somewhat clunky to use, especially in comparison to the shorthand notation offered by other languages, such as JavaScript. That has led to […]

OpenSSH 8.5 released
OpenSSH 8.5 has been released. It includes fixes for a couple of potential security problems (one of which only applies to Solaris hosts); it also enables UpdateHostKeys by default, allowing hosts with insecure keys to upgrade them without creating scary warnings for users. There are a lot of other small changes; see the announcement for details. […]

[$] PipeWire: The Linux audio/video bus
For more than a decade, PulseAudio has been serving the Linux desktop as its predominant audio mixing and routing daemon — and its audio API. Unfortunately, PulseAudio's internal architecture does not fit the growing sandboxed-applications use case, even though there have been attempts to amend that. PipeWire, a new daemon created (in part) out of these […]

From VBS, PowerShell, C Sharp, Process Hollowing to RAT, (Thu, Mar 4th) 4 Μαρτίου, 2021
VBS files are interesting to deliver malicious content to a victim&#39;s computer because they look like simple text files. I found an interesting sample that behaves like a dropper. But it looks also like Russian dolls seeing all the techniques used to drop a RAT at the end. The file hash is 8697dc74d7c07583f24488926fc6e117975f8a9f0149720 […]
