Snapchat says millions of user accounts compromised
SAN FRANCISCO (REUTERS) - Snapchat, a private messaging service, said it knew for months about a security loophole that allowed hackers this week to harvest millions of phone numbers and announced changes to its systems.
An anonymous group called Snapchat DB posted the usernames and phone numbers of 4.6 million Snapchat users on New Year's Eve, days after the startup - headed by 23-year old founder Evan Spiegel - brushed off warnings that its app still contained security loopholes.
The hacker group, which claimed to be based in the United States and Europe, made the entire database available for download but redacted the last two digits of every phone number.
Snapchat DB said it was working to raise awareness about Snapchat's security holes, not out of malicious intent.
