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 Łukasz 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
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

AI Solutions Are the New Shadow IT
Nov 22, 2023
AI Security / SaaS Security
Ambitious Employees Tout New AI Tools, Ignore Serious SaaS Security Risks Like the SaaS shadow IT of the past, AI is placing CISOs and cybersecurity teams in a tough but familiar spot. Employees are covertly using AI with little regard for established IT and cybersecurity review procedures. Considering ChatGPT's meteoric rise to 100 million users within 60 days of launch , especially with little sales and marketing fanfare, employee-driven demand for AI tools will only escalate. As new studies show some workers boost productivity by 40% using generative AI , the pressure for CISOs and their teams to fast-track AI adoption — and turn a blind eye to unsanctioned AI tool usage — is intensifying. But succumbing to these pressures can introduce serious SaaS data leakage and breach risks, particularly as employees flock to AI tools developed by small businesses, solopreneurs, and indie developers.

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
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
