The integrity and independence of external auditors are fundamental to maintaining transparency and trust in financial reporting. However, ethical challenges such as cronyism and favoritism continue to threaten audit quality, leading to compromised financial disclosures and increased risks of corporate fraud. This study explores the role of professional ethics in mitigating the effects of these unethical practices in external auditing. By examining the relationship between ethical principles, auditor independence, and financial misstatements, this research highlights the need for stronger regulatory frameworks and corporate governance mechanisms to prevent undue influence on audit decisions. Cronyism and favoritism, which arise when auditors develop close personal or financial ties with clients, undermine the objectivity required for an impartial audit process. The study assesses the impact of such practices on audit quality, drawing on theoretical and empirical evidence from high-profile corporate failures such as Enron and Wirecard. It also evaluates the effectiveness of existing ethical guidelines, including those issued by the International Ethics Standards Board for Accountants (IESBA) and the Public Company Accounting Oversight Board (PCAOB), as well as regulatory measures such as mandatory audit firm rotation and enhanced oversight mechanisms. Additionally, the research emphasizes the importance of ethical leadership, training, and education in fostering a culture of integrity within audit firms. Strengthening ethical awareness among auditors through continuous professional development is crucial in mitigating conflicts of interest and reinforcing auditor independence. The findings of this study contribute to the discourse on audit ethics by offering recommendations for improving ethical accountability, regulatory enforcement, and professional conduct in external auditing
