Boffins build automated Android bug hunting system

Researchers from Nanjing University and The University of Sydney have developed an AI vulnerability identification system called A2, which is designed to discover and validate vulnerabilities in Android applications. A2 achieves 78.3 percent coverage on the Ghera benchmark, outperforming static analyzers like APKHunt, which only reaches 30.0 percent. In testing on 169 production APKs, A2 identified 104 true-positive zero-day vulnerabilities, with 57 validated through automatically generated proof-of-concept exploits. One identified vulnerability was a medium-severity flaw in an Android app with over 10 million installs, specifically an intent redirect issue. A2 integrates various commercial AI models for planning, execution, and validation of tasks, improving upon its predecessor, A1, which lacked robust validation. The system effectively reduces false positives by providing valuable signals rather than overwhelming noise.

Perplexity’s Android App Is Infested With Security Flaws, Report Finds

Perplexity has launched a promotional campaign called “Ask like a millionaire,” offering a million-dollar prize to users who download its app, refer friends, and engage with it during the Super Bowl. However, the Android app is facing scrutiny due to significant security vulnerabilities, including issues that could lead to data theft and account takeovers. A report from Appknox reveals that the app's API can be accessed without restriction, and the code contains hardcoded secrets, making it easy for attackers to create counterfeit versions of the app. The app is also vulnerable to task hijacking, which could allow unauthorized access to sensitive data. Perplexity, founded in 2022, has raised 0 million in venture capital and has over 10 million downloads. The company is exploring partnerships with smartphone manufacturers and has faced criticism for alleged copyright infringement. Security experts advise users to consider removing the app until the issues are resolved.
