Internal system broadcasts happening inside the Android OS expose sensitive user and device details that apps installed on the phone can access without the user's knowledge or permission. The leaked data includes details such as the WiFi network name, WiFi network BSSID, local IP addresses, DNS server information, and the device's MAC address. This type of data might look innocuous, but it can be used to track users online and determine a user's real-world location. The leak happens because of an internal feature of the Android OS named "intents." Intents allow an app or the OS itself to send an internal system-wide message that can be read by all apps and OS functions running on an Android device. Mobile security researchers from Nightwatch Cybersecurity have discovered that the Android OS broadcasts information about the WiFi connection and the WiFi network interface via two separate intents —WifiManager's NETWORK_STATE_CHANGED_ACTION and WifiP2pManager's WIFI_P2P_THIS_DEVICE_CHANGED_ACTION. Apps installed on an Android —including their advertising components— can set up listening posts for these two intents and capture WiFi-related information even if they don't have the permission to access a phone's WiFi feature (granted by the user to apps at install time). This leak completely undermines the Android permission system, as it allows applications access to highly sensitive information without prompting the user for action. For example, an advertiser or a malicious threat actor who have tricked a user into installing a benign-looking app can harvest WiFi info from system-wide intents and use this data to query public databases of known BSSID identifiers —such as WiGLE or SkyHook— and track down a user's real-world location. In this scenario, the app doesn't need to ask for the WiFi Access permission, and indirectly through the harvested data, the Location Access permission as well.

According to reports, a security researcher has discovered an unpatched vulnerability in the Windows 10 operating system. The security researcher reportedly revealed the vulnerability on Twitter. It’s a zero-day flaw that exists in Windows 10 and it could allow an attacker to gain system privileges on an affected computer, according to CERT/CC vulnerability analyst Phil Dormann. The vulnerability was disclosed in a tweet by @SandboxEscaper and the account has been removed. It appears that vulnerability exists in task scheduler on Windows 10 but there’s no easy way to exploit the security flaw. The successful exploitation of the vulnerability requires the user to download a malicious app on a machine. “Microsoft Windows task scheduler contains a local privilege escalation vulnerability in the Advanced Local Procedure Call (ALPC) interface, which can allow a local user to obtain SYSTEM privileges,” the advisory reads. “Microsoft Windows task scheduler contains a vulnerability in the handling of ALPC, which can allow a local user to gain SYSTEM privileges. A local user may be able to gain elevated (SYSTEM) privileges.” “A local user may be able to gain elevated (SYSTEM) privileges,” the advisory explains. Another report claims that the patch for the said vulnerability may land soon. There’s a chance that Microsoft will deploy updates to address this vulnerability on next Patch Tuesday, which takes place on September 11. For more stop by OUR FORUM.

Current versions of Ubuntu and CentOS are disabling a security feature that was added to the GNOME desktop environment last year. The feature's name is Bubblewrap, which is a sandbox environment that the GNOME Project added to secure GNOME's thumbnail parsers in July 2017, with the release of GNOME 3.26. Thumbnail parsers are scripts that read files inside a directory and create thumbnail images to be used with GNOME, KDE, or other Linux desktop environments. This operation takes place every time a user navigates to folders, and the OS needs to display thumbnails for the files contained within. In recent years, security researchers have proven that thumbnail parses can be an attack vector when hackers trick a user into downloading a boobytrapped file on their desktop, which is then executed by the thumbnail parser. It's for this reason that the GNOME team added Bubblewrap sandboxes for all GNOME thumbnail parser scripts last year. But according to German security researcher and journalist Hanno Boeck, the Ubuntu operating system is disabling Bubblewrap support inside GNOME for all recent OS versions. Furthermore, Google security researcher Tavis Ormandy also discovered that GNOME Bubblewrap sandboxes were also missing in the default version of CentOS 7.x. But there's a valid explanation for what Ubuntu is doing, according to Alex Murray, Ubuntu Security Tech Lead at Canonical. Murray says the Ubuntu team opted to disable GNOME's Bubblewrap because they did not have the time and resources to audit the feature. Learn more by visiting OUR FORUM.

Google security researchers have revealed this week that the immensely popular Fortnite Android app is vulnerable to so-called man-in-the-disk (MitD) attacks. This vulnerability allows low-privileged malicious apps already installed on a users' phone to hijack the Fortnite app's installation process and install other malicious apps that have a higher permissions level. Epic Games, the Fortnite game developer, has released version 2.1.0 that patches this attack vector. The concept of man-in-the-disk attacks has been recently detailed in more depth by security researchers from Israel-based cyber-security firm Check Point. In a simplified explanation, MitD attacks are possible when an Android app stores data on External Storage mediums, outside its highly-secured Internal Storage space. An attacker can watch a specific app's External Storage space and tamper with the data stored in this storage space because this space is shared by all apps. The Fortnite app is vulnerable to this attack because the app does not contain the actual game, but is merely an installer. Once users install the app, this installer uses the device's External Storage space to download and install the actual game. "Any app with the WRITE_EXTERNAL_STORAGE permission can substitute the APK immediately after the download is completed and the fingerprint is verified. "Any app with the WRITE_EXTERNAL_STORAGE permission can substitute the APK immediately after the download is completed and the fingerprint is verified. This is easily done using a FileObserver. The Fortnite Installer will proceed to install the substituted (fake) APK," a Google researcher wrote in a bug report recently made public.Complete details are posted on OUR FORUM.

Millions of mobile devices from eleven smartphone vendors are vulnerable to attacks carried out using AT commands, a team of security researchers has discovered. AT (ATtention) commands or the Hayes command set, is a collection of short-string commands developed in the early 1980s that were designed to be transmitted via phone lines and control modems. Different AT command strings can be merged together to tell a modem to dial, hang up, or change connection parameters. Unknown to the common user is that modern smartphones include a basic modem component inside them, which allows the smartphone to connect to the Internet via its telephony function, and more. While international telecommunications bodies have standardized basic AT commands, dictating a list that all smartphones must support, vendors have also added custom AT command sets to their own devices —commands which can control some pretty dangerous phone features such as the touchscreen interface, the device's camera, and more. In massive and groundbreaking research, a team of eleven scientists from the University of Florida, Stony Brook University, and Samsung Research America, have looked into what types of AT commands are currently supported on modern Android devices. The research team analyzed over 2,000 Android firmware images from eleven Android OEMs such as ASUS, Google, HTC, Huawei, Lenovo, LG, LineageOS, Motorola, Samsung, Sony, and ZTE. They say they discovered that these devices support over 3,500 different types of AT commands, some of which grant access to very dangerous functions. Videos and more are posted on OUR FORUM.
