DALLAS – Heritage Auctions (ha.com), a victim of a malware attack over the weekend, has restored its website and online auctions.

"Thank you for your patience as we bring our website back online. Any auctions currently open or opening soon have updates closing times," Heritage said in a statement to customers.

Heritage customers are now able to resume bidding and tracking auctions, the company said. Bids placed anytime last Friday (Oct. 18) may not have been recorded. Customers are being asked to check their "MyBids" on the site and update accordingly or contact the company's client services for assistance.

The malware attack effectively shut down the company's website and halted online auctions. The company assured customers that "client financial information (e.g. credit card, bank account info, etc.) is maintained by a third-party provider and is thus not affected” by the disruption.

Heritage Auctions touts itself as the largest fine art and collectibles auction house founded in the United States, and the world's largest collectibles auctioneer. Heritage maintains offices in New York, Dallas, Beverly Hills, San Francisco, Chicago, Palm Beach, London, Paris, Geneva, Amsterdam and Hong Kong. The company's auction-house site is wildly popular, having more than one million registered bidder-members.
