In a recent forum posting, Dropbox announced that it has "brought in a team of outside experts" to investigate reports of spam being sent to e-mail addresses associated with Dropbox accounts.

"The forum has six pages worth of complaints from mostly European users getting spam from 'Euro Dice Exchange' and other online casinos and shady-sounding senders," writes Ars Technica's Ian Lamont. "While everyone gets e-mail spam, users raised a flag because the messages were often coming to accounts used only for Dropbox."

"[One] user wrote that he immediately closed down his Dropbox account after receiving the spam and opened a fresh account," writes PCWorld's Jeremy Kirk. "But the new one -- also only linked with a unique email address not used for any other registrations -- was hit immediately."

"Although the spam is being sent to different countries in Europe, it arrives in the user's native language, suggesting this is a very coordinated attack," writes ZDNet's Emil Protalinski. "The spam e-mails advertise different domain names, but all of them have been created very recently, use Russian DNS servers, and are registered at Bizcn."

"Dropbox said it doesn't believe the issue has led to any unauthorized activity on any of its users' accounts," writes The Los Angeles Times' Salvador Rodriguez. "'We’ve taken a number of precautionary steps and continue to work around the clock to make sure your information is safe,' the company said."
