New 5G Modem Flaws Affect iOS Devices and Android Models from Major Brands

New 5G Modem Flaws Affect iOS Devices and Android Models from Major Brands
Dec 08, 2023 Vulnerability / Mobile Network
A collection of security flaws in the firmware implementation of 5G mobile network modems from major chipset vendors such as MediaTek and Qualcomm impact USB and IoT modems as well as hundreds of smartphone models running Android and iOS. Of the 14 flaws – collectively called  5Ghoul  (a combination of "5G" and "Ghoul") – 10 affect 5G modems from the two companies, out of which three have been classified as high-severity vulnerabilities. "5Ghoul vulnerabilities may be exploited to continuously launch attacks to drop the connections, freeze the connection that involve manual reboot or downgrade the 5G connectivity to 4G," the researchers  said  in a study published today. As many as 714 smartphones from 24 brands are impacted, including those from Vivo, Xiaomi, OPPO, Samsung, Honor, Motorola, realme, OnePlus, Huawei, ZTE, Asus, Sony, Meizu, Nokia, Apple, and Google. The vulnerabilities were disclosed by a team of researchers from the ASSET (Automated

Hackers Sign Android Malware Apps with Compromised Platform Certificates

Hackers Sign Android Malware Apps with Compromised Platform Certificates
Dec 02, 2022 Mobile Security / Attack Vector
Platform certificates used by Android smartphone vendors like Samsung, LG, and MediaTek have been found to be abused to sign malicious apps. The findings were first  discovered and reported  by Google reverse engineer Ɓukasz Siewierski on Thursday. "A platform certificate is the application signing certificate used to sign the 'android' application on the system image," a report filed through the Android Partner Vulnerability Initiative ( AVPI )  reads . "The 'android' application runs with a highly privileged user id – android.uid.system – and holds system permissions, including permissions to access user data." This effectively means that a rogue application signed with the same certificate can gain the highest level of privileges as the Android operating system, permitting it to harvest all kinds of sensitive information from a compromised device. The list of malicious Android app packages that have abused the certificates is below - com.

Xiaomi Phones with MediaTek Chips Found Vulnerable to Forged Payments

Xiaomi Phones with MediaTek Chips Found Vulnerable to Forged Payments
Aug 12, 2022
Security flaws have been identified in Xiaomi Redmi Note 9T and Redmi Note 11 models, which could be exploited to disable the mobile payment mechanism and even forge transactions via a rogue Android app installed on the devices. Check Point said it found the flaws in devices powered by MediaTek chipsets during a security analysis of the Chinese handset maker's Trusted Execution Environment (TEE), which is used to perform mobile payment signatures A TEE refers to a  secure enclave  inside the main processor that's used to process and store sensitive information such as cryptographic keys so as to ensure confidentiality and integrity. Specifically, the Israeli cybersecurity firm discovered that a trusted app on a Xiaomi device can be downgraded due to a lack of version control, enabling an attacker to replace a newer, secure version of an app with an older, vulnerable variant. "Therefore, an attacker can bypass security fixes made by Xiaomi or MediaTek in trusted apps

SHQ Response Platform and Risk Centre to Enable Management and Analysts Alike

SHQ Response Platform and Risk Centre to Enable Management and Analysts Alike
May 13, 2024Threat Detection / SoC / SIEM
In the last decade, there has been a growing disconnect between front-line analysts and senior management in IT and Cybersecurity. Well-documented challenges facing modern analysts revolve around a high volume of alerts, false positives, poor visibility of technical environments, and analysts spending too much time on manual tasks. The Impact of Alert Fatigue and False Positives  Analysts are overwhelmed with alerts. The knock-on effect of this is that fatigued analysts are at risk of missing key details in incidents, and often conduct time-consuming triaging tasks manually only to end up copying and pasting a generic closing comment into a false positive alert.  It is likely that there will always be false positives. And many would argue that a false positive is better than a false negative. But for proactive actions to be made, we must move closer to the heart of an incident. That requires diving into how analysts conduct the triage and investigation process. SHQ Response Platfo

Eavesdropping Bugs in MediaTek Chips Affect 37% of All Smartphones and IoT Globally

Eavesdropping Bugs in MediaTek Chips Affect 37% of All Smartphones and IoT Globally
Nov 24, 2021
Multiple security weaknesses have been disclosed in MediaTek system-on-chips (SoCs) that could have enabled a threat actor to elevate privileges and execute arbitrary code in the firmware of the audio processor, effectively allowing the attackers to carry out a "massive eavesdrop campaign" without the users' knowledge. The discovery of the flaws is the result of reverse-engineering the Taiwanese company's audio digital signal processor ( DSP ) unit by Israeli cybersecurity firm Check Point Research, ultimately finding that by stringing them together with other flaws present in a smartphone manufacturer's libraries, the issues uncovered in the chip could lead to local privilege escalation from an Android application.  "A malformed inter-processor message could potentially be used by an attacker to execute and hide malicious code inside the DSP firmware," Check Point security researcher Slava Makkaveev  said  in a report. "Since the DSP firmware h

Hacking Smartphones Running on MediaTek Processors

Hacking Smartphones Running on MediaTek Processors
Feb 01, 2016
A dangerous backdoor has been discovered in the MediaTek processor that could be exploited to hack Android devices remotely. MediaTek is a Taiwan-based hardware company that manufacture hardware chips and processor used in the smartphones and tablets. The backdoor was discovered by security researcher Justin Case , who already informed MediaTek about the security issue via Twitter, as the chipset manufacturer had no proper vulnerability reporting mechanism in place. The vulnerability is apparently due to a debug tool that was opened up for carriers to test the device on their networks, but unfortunately, it was left open in the shipped devices, thus leaving the serious backdoor open to hackers. If exploited, the debug feature could allow hackers to compromise personal data of an Android device, including user's private contacts, messages, photos, videos and other private data. MediaTek acknowledged the issue, saying "We are aware of this issue, and it has bee
