Paper of the Week:

Paper Title: Targeting the Weakest Link: Social Engineering Attacks in Ethereum Smart Contracts.

TLDR:

  1. This work explores the possibility and existence of new social engineering attacks beyond smart contract honeypots.

  2. It presents two novel classes of Ethereum social engineering attacks — Address Manipulation and Homograph — and develops six zero-day social engineering attacks.

  3. To show how the attacks can be used in popular programming patterns, it conducts a case study of five popular smart contracts with combined market capitalization exceeding $29 billion, and integrates the attack patterns in their source codes without altering their existing functionality.

  4. Moreover, it shows that these attacks remain dormant during the test phase but activates their malicious logic only at the final production deployment.

  5. The work further analyzes 85,656 open-source smart contracts, and discovers that 1,027 of them can be used for the proposed social engineering attacks.

  6. It conducts a professional opinion survey with experts from seven smart contract auditing firms, corroborating that the exposed social engineering attacks bring a major threat to the smart contract systems.
