Extensive Abuse of High-Ranking Websites for Large-Scale Illicit Promotion via Reflected Search Poisoning

Concetti Chiave

Reflected search poisoning (RSP) allows miscreants to free-ride the reputation of high-ranking websites and efficiently distribute a large volume of illicit promotion texts (IPTs) across major search engines, exposing regular search users to a diverse range of illegal goods and services.

Sintesi

The study makes the following key observations:

1. RSP-based IPTs are large-scale, continuously growing, and diverse in both illicit categories and natural languages. Over 11 million distinct IPTs belonging to 14 different illicit categories have been identified, promoting goods and services such as drug trading, data theft, counterfeit goods, and hacking services.

2. High-ranking websites have been heavily abused in RSP attacks, with 20,330 of the abused websites ranking in the top 1 million most popular websites, 2,113 in the top 10,000, and 854 being renowned educational institutions or 1,144 government agencies.

3. Regular search users are extensively exposed to IPTs, with 46% of searches for popular city names in China returning at least one IPT in the top 10 search results.

4. The underlying illicit promotion campaigns are operated on a large scale, with 83.62% of IPTs embedding instant messaging contacts as the next hops for victims to further interact with the operators.

The study highlights the negative security implications of RSP-driven illicit promotion and calls for more efforts to mitigate this emerging threat.

How can search engines further improve their filtering capabilities to effectively detect and remove RSP-based IPTs across different languages?

To enhance their filtering capabilities and effectively detect and remove RSP-based IPTs across different languages, search engines can implement the following strategies:

Multilingual Detection Models: Develop and deploy advanced multilingual detection models that can accurately identify and classify IPTs in various languages. These models should be trained on diverse datasets to ensure robust performance across different linguistic contexts.

Language-Agnostic Features: Incorporate language-agnostic features in the detection algorithms to capture common patterns and characteristics of IPTs regardless of the language in which they are written. This approach can help improve the detection accuracy for multilingual content.

Continuous Monitoring and Updates: Implement real-time monitoring of search results to quickly identify and flag suspicious IPTs. Regular updates to the detection algorithms based on new trends and emerging patterns in RSP-based illicit promotion can further enhance filtering capabilities.

Collaboration with Linguistic Experts: Collaborate with linguistic experts and researchers to gain insights into language-specific nuances and linguistic markers of illicit content. This collaboration can help refine detection algorithms and improve accuracy in identifying IPTs across different languages.

User Reporting Mechanisms: Implement user reporting mechanisms that allow users to flag potentially harmful or illicit content. User feedback can supplement automated detection systems and help search engines stay vigilant against RSP-based IPTs in multiple languages.

Cross-Platform Data Sharing: Establish partnerships and data-sharing agreements with other search engines and online platforms to exchange information on known IPTs and RSP tactics. This collaborative approach can create a unified front against illicit promotion campaigns across different languages.

By implementing these strategies, search engines can strengthen their filtering capabilities and effectively combat RSP-based IPTs in diverse languages, thereby enhancing the overall security and integrity of search results.

What are the potential legal and ethical implications of the diverse range of illicit goods and services being promoted through RSP, and how should policymakers and law enforcement respond?
