How to navigate Poshmark safely: Tips to buy and sell while avoiding scams

Feb 21, 2026 | Threat Intelligence Research

Social Commerce Platforms Are Hotbeds for Fraud: A Close Look at Poshmark’s Vulnerabilities

Fraudsters are exploiting the booming social commerce market, targeting platforms like Poshmark due to their ease of use and high commission fees. These scams put both buyers and sellers at risk by compromising their personal information and funds.

The rise of social commerce has created a landscape where scams flourish, particularly on platforms such as Poshmark, which connects users to buy and sell fashion items. The company, based in California, is grappling with various fraudulent activities encouraged by factors like a 20% transaction fee on items over $15, leading users to complete deals off-platform. This exposes them to phishing, counterfeit goods, and refund scams that can quickly turn a profitable sale into a financial loss. Additionally, the lack of private communication channels makes it easier for scammers to divert discussions away from the platform.

Common scams include phishing attempts disguised as official communication from Poshmark, urging users to disclose sensitive data. Off-platform payment scams are prevalent, where opportunistic fraudsters entice users to avoid commissions by completing transactions outside Poshmark, often resulting in financial loss. Other noteworthy scams involve buyers claiming items are missing to secure refunds while retaining the merchandise or leveraging counterfeit returns, putting sellers at a disadvantage.

Why this matters: As social commerce continues to grow, the risks associated with online transactions rise significantly, necessitating vigilant defense strategies to mitigate potential losses.

To counter these threats, implementing vigilant monitoring, using identity protection tools, and utilizing a robust SIEM can significantly reduce risks associated with these scams. Awareness of transaction protocols and leveraging platform-specific protections can safeguard users.
