In one of the month’s least reported hacks, Groupon India, known in that country as SoSasta.com, suffered a hack that exposed the e-mail addresses and plain-text passwords for 300,000 users, as well as the SQL file index on Google.

SoSasta, which offers services in 11 major Indian cities -- Kolkata, Hyderabad, Pune, Ahmedabad, Delhi/NCR, Chandigarh, Jaipur, Nagpur, Mumbai, Chennai and Bengaluru -- contacted customers via e-mail that they had been affected by the breach.

In the e-mail, SoSasta said that it had been ’alerted to a security issue’ and recommended that users change their passwords, especially if they used the same passwords for other sites.

SoSasta said, however, that the breach did not compromise any customer credit or debit card data.
