“Phishing scams pose a heightened threat during tax season, as cybercriminals exploit the urgency and complexity of filing taxes to target unsuspecting taxpayers and tax professionals.

Client scams specifically taking aim at tax professionals with the 2024 filing season is a novel approach and shows how tactics evolve. Tax professionals and taxpayers alike are urged to exercise extreme caution of any requests for sensitive information by verifying the identity of the sender via secondary communication methods and never clicking on any links or attachments until their authenticity can be verified.
As tax season unfolds - and in general-  adopting cybersecurity best practices and enlisting professional cybersecurity services (such as monitoring and Phishing Email Analysis) becomes imperative in safeguarding personal and financial data from the evolving landscape of cyber threats.

Hunter Landry, Senior SOC Analyst at Ingalls Information Security


“Professional monitoring and personal vigilance are integral parts of the fabric that makes up safeguarding financial service activities. This warning from the IRS Security Summit is a timely reminder that a proactive approach in developing comprehensive strategies for evolving threats is needed.

Regular review of an organization's security measures such as email filtering, MFA, encryption of data, as well as education surrounding policies relating to communications remain top recommendations.
