Shares of Victoria’s Secret fell Wednesday after the lingerie company took down its US website, saying there was a prolonged “security incident.”

Victoria’s Secret has taken down its U.S. website and says some in-store services will be unavailable as it addresses a “security incident.”

Victoria’s Secret’s website remained offline on Thursday, days after the lingerie company was hit by a cyberattack that has disrupted its online sales and sent its stock price lower.
