Move Inc. says its websites, including realtor.com and Top Producer, have been stable since Saturday after being hit by a cyberattack that disrupted them for several days last week.
Move CEO Steve Berkowitz restated previous assurances by Move that there was no evidence that any sensitive information was compromised during the "distributed denial of service" (DDoS) cyberattack that hit several Move sites beginning on Tuesday, June 17.

"This was a frustrating experience, but we have no reason to believe this attack jeopardized any consumer information, customer information, or website security," Berkowitz in a statement.
DDoS attackers overwhelm target sites with traffic, sometimes demanding money to turn off the attack. Move says it received a ransom demand, which it refused to pay, instead moving to migrate its system to a different network architecture.
Move hired Prolexic, a division of Akamai Technologies that specializes in DDoS defense, to help defend against the attack.
Move is not alone in fighting DDoS attacks, Berkowitz noted. Large DDoS attacks have become more prevalent across the Internet landscape recently.
Other recent victims of DDoS attacks include Evernote, Twitter's popular messaging app TweetDeck, RSS reader Feedly, video site Vimeo, project management platform Basecamp, and inbound marketing tech firm Moz.
Move has been hit with DDoS attacks before and has defended itself, but this one was too big for its defenses, Berkowitz said. The firm has engaged Prolexic to help it beef up its security against any future DDoS attacks, he said.
Move's chief competitors Zillow and Trulia would not say whether they had similar protections against DDoS attacks in place.
