An update notes that multiple workarounds now allow certificate injection. ### Source excerpt Update: This post sparked a lot of excellent discussion and debate on workarounds, and there are now multiple working solutions to allow certificate injection on Android 14, despite the restrictions discussed here. See the update post for more details. When Android was initially announced in 2007 by the Open Handset Alliance (headed by Google) their flagship project was billed as an "open platform", "providing developers a new level of openness", and giving them "complete access to handset capabilities and tools". We've come a long way since then, steadily retreating from openness & user control of devices, and shifting towards a far more locked-down vendor-controlled world. The next step of Android's evolution is Android 14 (API v34, codename Upside-Down Cake) and it takes more steps down that path. In this new release, the restrictions around certificate authority (CA) certificates become significantly tighter, and appear to make it impossible to modify the set of trusted certificates at all, even on fully rooted devices. If you're an Android developer, tester, reverse engineer, or anybody else interested in directly controlling who your device trusts, this is going to create some new challenges. Before we get into the finer details, first I want to talk a little about the context around Android CA management and how we got here, but if you want to jump to the latest details you can go straight to the Enter Android 14 section below. "Open Software, Open Device, Open Ecosystem" While the initial principles of Android were very much focused on open software, controllable by users and developers, over more recent years Android has increasingly limited the control of users, developers & researchers over their own devices. The key turning point in this process was Android 7 (Nougat, released in 2016) in which the certificate authorities (CAs) on the device that were previously fully modifiable by the owner of the phone were split in two: one fixed list of CAs provided ## Mobian Security Update #1 DevFeed: [Mobian Security Update #1]() Original publisher: [Read original article]() Author: Mobian team Published: 2023-08-31T02:00:00Z Content type: release Language: en Sources: [Mobian's Blog]() Topics: [Security](), [vulnerability](), [apt](), [Package manager](), [upgrade]() Tags: [apt](), [packages](), [permissions](), [root](), [security](), [update](), [vulnerability]() ### AI overview The Mobian Team released a security update for a local vulnerability in Bookworm images. Some files had global write permissions, including files managing apt configuration, creating a possible privilege-escalation path to root for a local user with access to an unlocked or already compromised device. Mobian users should upgrade the specified mobian-tweaks-common package. ### Source excerpt The Mobian Team have recently released a security update fixing a local vulnerability caused by a bug in our Bookworm images. User Action Required Mobian users must install the following package in order to address the issues described in this post. A normal upgrade which can be done using sudo apt update && sudo apt upgrade or via Gnome Software will take care of this. For Bookworm users: mobian-tweaks-common, version 0.5.6+deb12u1 For Trixie and Staging users: mobian-tweaks-common, version 0.5.9 These packages include an install script which fixes the permissions on the effected files. They are currently in the staging and bookworm-updates repositories and will migrate to trixie and bookworm in the coming week. Summary The Bookworm images released earlier this year had a small number of files with global write permissions. As two of these files manage the configuration of the apt package manager, they provide an attacker with a useful privilege escalation method. This issue seems to only affect the released Bookworm images, though a full audit of weekly images has not been undertaken. Users who installed on Trixie were likely never effected. Impact These files could allow a local user to gain root access to the device by modifying them and waiting for the user to install an attacker provided update. This attack would require access to an unlocked or otherwise already compromised device as a standard user. There is no way to carry this attack out remotely or on a locked device. Indicators of Compromise Users can verify the current configuration of their system by checking the relevant files. Changes to these files to not immediately mean the device has been compromised, but may warrant further investigation. /etc/apt/sources.list.d/mobian.list should contain (potentially with a different distribution): deb http://repo.mobian.org/ main non-free-firmware /etc/apt/trusted.gpg.d/mobian.gpg can be verified using the command shasum -c checksum.txt aganist ## Requesting Just-in-Time access to Amazon EC2 Instances via Slack DevFeed: [Requesting Just-in-Time access to Amazon EC2 Instances via Slack]() Original publisher: [Read original article]() Author: info@goteleport.com (Janakiram MSV) Published: 2022-04-13T00:00:00Z Content type: tutorial Language: en Sources: [Teleport]() Topics: [Amazon EC2](), [Slack](), [DevOps](), [Messaging]() Tags: [amazon-ec2](), [aws](), [devops](), [ec2](), [enterprise](), [how-to](), [identity](), [integration](), [request](), [root](), [server](), [slack](), [third-party](), [tutorial](), [workflows]() ### AI overview This tutorial explains how to configure just-in-time privilege escalation for Amazon EC2 instances using Teleport RBAC and Slack.

It shows that using the current-directory operand for chown avoids wildcard expansion and uses find with -exec to move JSON files individually. ### Source excerpt Right now I have a directory with about 750,000 odd files in it and any attempt to manipulate the files results in this: root@ip-172-31-1-219:~/datastreamer/data# mv * /home/ubuntu/data/data bash: /bin/mv: Argument list too long My first challenge was to do this: chown ubuntu:ubuntu * And the fix for this one was actually easy: chown ubuntu:ubuntu . By omitting the *, the bash limits on argument list don't apply - this changes the current folder (.) and everything in it and it always works. The second challenge was to move the files from /root/datastreamer/data to /home/ubuntu/data/data. Here's the solution after a bit of research: find /root/datastreamer/data -name '*.json' -exec mv {} /home/ubuntu/data/data \; Reference: Unix.StackExchange StackOverflow ## The 1.x Files: The State of Stateless Ethereum DevFeed: [The 1.x Files: The State of Stateless Ethereum]() Original publisher: [Read original article]() Author: Griffin Ichiba Hotchkiss Published: 2019-12-30T00:00:00Z Content type: article Language: en Sources: [Ethereum Foundation Blog]() Topics: [Ethereum](), [Data structures](), [client](), [Protocol (disambiguation)]() Tags: [data-structure](), [ethereum](), [hashing](), [node](), [protocol](), [research-development](), [retrieval](), [root](), [state](), [stateless]() ### AI overview This deep dive explains Ethereum state and the stateless client direction of Eth 1.x research.

They accessed its UART root shell using a Raspberry Pi, dumped the flash memory, located the MAC address in an NVRAM partition, replaced it, and found that the modem still refused to establish a connection. The supplied text ends before the investigation is completed. ### Source excerpt Recently, I stumbled upon an old cable modem sitting next to the dumpster. An neighbor just moved out and they threw away boxes of old junk. I was excited because the modem is much better than the one I currently use and has fancy features like built in 5GHz WiFi and DOCSIS 3.0 support. When I called my Internet service provider to activate it though, they told me that the modem was tied to another account likely because the neighbors did not deactivate the device before throwing it away. The technician doesn't have access to their account so I would have to either wait for it to be inactive or somehow find them and somehow convince them to help me set up the modem they threw away. ## Reduce, reuse, recycle DevFeed: [Reduce, reuse, recycle]() Original publisher: [Read original article]() Author: gbrown-mozilla Published: 2016-03-10T23:53:41Z Content type: tutorial Language: en Sources: [Mozilla Automation]() Topics: [LineageOS](), [USB](), [Ubuntu](), [make](), [Java](), [Assembly](), [Bash]() Tags: [android](), [aosp](), [boot](), [build](), [building](), [firefox](), [firefox-for-android](), [java](), [make](), [mozilla](), [phones](), [root](), [testing](), [usb]() ### AI overview The article describes rebuilding AOSP on Ubuntu 14.04 and flashing Android 4.3 onto a Galaxy Nexus after older Android versions could no longer run current Firefox for Android builds.

It contrasts the Linear map with the simpler Crude map and describes how table migration enables continued concurrent operations. ### Source excerpt In an earlier post, I showed how to implement the "world's simplest lock-free hash table" in C++. It was so simple that you couldn't even delete entries or resize the table. Well, a few years have passed since then, and I've recently written some concurrent maps without those limitations. You'll find them in my Junction project on GitHub. Junction contains several concurrent maps - even the 'world's simplest' is there, under the name ConcurrentMap_Crude. For brevity, let's call that one the Crude map. In this post, I'll explain the difference between the Crude map and Junction's Linear map. Linear is the simplest Junction map that supports both resize and delete. You can review the original post for an explanation of how the Crude map works. To recap: It's based on open addressing and linear probing. That means it's basically a big array of keys and values using a linear search. When inserting or looking up a given key, you hash the key to determine where to begin the search. Concurrent inserts and lookups are permitted. Junction's Linear map is based on the same principle, except that when the array gets too full, its entire contents are migrated to a new, larger array. When the migration completes, the old table is replaced with the old one. So, how do we achieve that while still allowing concurrent operations? The Linear map's approach is based on Cliff Click's non-blocking hash map in Java, but has a few differences. The Data Structure First, we need to modify our data structure a little bit. The original Crude map had two data members: A pointer m_cells and an integer m_sizeMask. The Linear map instead has a single data member m_root, which points to a Table structure followed by the cells themselves in a single, contiguous memory block. In the Table structure, there's a new shared counter cellsRemaining, initially set to 75% of the table size. Whenever a thread tries to insert a new key, it decrements cellsRemaining first. If it decrements cellsRemaining below ## Install WordPress from command-line DevFeed: [Install WordPress from command-line]() Original publisher: [Read original article]() Author: Tom Published: 2016-02-15T00:00:00Z Content type: tutorial Language: en Sources: [Tomasz Gągor]() Topics: [WordPress](), [Command-line interface](), [apt](), [chmod](), [cURL](), [MySQL]() Tags: [apt](), [bash](), [chmod](), [cli](), [command-line](), [curl](), [install](), [mysql](), [root](), [wordpress]() ### AI overview A tutorial showing how to install WordPress from the command line using WP-CLI, including prerequisites, downloading the WP-CLI executable, checking it, and installing WordPress as the web application user. ### Source excerpt I never tried it before but today I needed to install WordPress...

The article attributes the problem to old telephony databases and recommends deleting two related data directories, then restarting the phone. ### Source excerpt I have a good old nexus 4 still trying to keep up with the big boys in the market. After google ditched the plans of releasing the latest android 6.0 - Marshmallow for nexus 4, things didn't look so great. But with the release of CM 13 (mako), even nexus 4 has android 6.0! Previously, I was running CM 12.1 and I dirty flashed CM 13 on top of it. Although it doesn't have all the features that CM 12 had, with time, the awesome guys in XDA and cyanogen will port all the features to CM 13. After dirty flashing CM 13 on top of CM 12.1, I faced some problems. First of all, things were kinda slow. So I went to Developer options in Settings and set all the Animation scaling to .5x. This considerable made things faster. Secondly and more importantly, my sim card was not getting detected and I was getting a ton loads of popups saying "Unfortunately the process com.android.phone has stopped". I looked at the logcat to see what is going wrong and I found that this was appearing a lot of times. Clearly, the problem was with com.android.providers.telephony. Upon looking closely, the problem was related to CursorWindow and Cursor. Hence, the problem was not with CM 13 but with the old database left behind by CM 12.1. Solution Just delete the folders /data/data/com.android.providers.telephony and /data/data/com.android.phone using some tool like Root Explorer or you can do this in adb shell. rm -rf /data/data/com.android.providers.telephony rm -rf /data/data/com.android.phone Then, restart the phone. ## Using WRITE\_SECURE\_SETTINGS permission on non system apps DevFeed: [Using WRITE\_SECURE\_SETTINGS permission on non system apps]() Original publisher: [Read original article]() Author: Suresh Alse (noreply@blogger.com) Published: 2015-10-25T08:44:00Z Content type: tutorial Language: en Sources: [Life Plus Linux]() Topics: [Android](), [Wireless Debugging](), [App](), [APK](), [Code]() Tags: [adb](), [android](), [apk](), [app](), [code](), [permission](), [root]() ### AI overview A tutorial explains how an Android application can obtain the WRITE_SECURE_SETTINGS permission despite it being unavailable to non-system apps. It describes granting the permission with ADB or running the command from a root shell, noting that root access is required for the programmatic approach. ### Source excerpt I happen to frequently use an app that doesn't work if USB Debugging - ADB (Android Debug Bridge) is enabled. It is very cumbersome to go to settings and enable or disable the setting every time I need to use the app. I checked if there are any widgets that could do this in a click and returned empty handed. So, I did what every developer would do - build it myself! In order to change the adb settings, I had to use WRITE_SECURE_SETTINGS permission. But there was one major problem! This permission is not available for non system apps!! The easiest solution to this was to move the apk to /system partition. Except that I didn't want to do this as I frequently keep flashing /system partition. Another solution was to use pm and grant permission to the app like this: adb pm grant android.permission.WRITE_SECURE_SETTINGS This was great! However I didn't want users who were gonna use the app to go through all this pain. I had to figure out a way to do the same programmatically. So I did the next best thing! To run the command after opening a root shell in the code. Here is how I did it. This requires root. But that's ok. [Next page]()
