The corporate has realized the arduous means that there are higher methods to ship two-factor authentication than through textual content messages
Reddit has introduced {that a} hacker has damaged into a few of its programs and accessed some person knowledge, together with an previous database backup copy containing person credentials, electronic mail addresses, and messages. Moreover, the breach affected the usernames and related electronic mail addresses of “redditors” who acquired electronic mail digests this previous June, in keeping with an announcement by the location’s chief expertise officer Christopher Slowe.
The incident happened between June 14-18, with the corporate studying about it on June 19. “Since then we’ve been conducting a painstaking investigation to determine simply what was accessed, and to enhance our programs and processes to forestall this from taking place once more,” stated Slowe.
So what precisely was compromised? For one factor, a database backup containing cryptographically salted and hashed password knowledge from the interval between the location’s launch in 2005 and May 2007. Additionally accessed have been person names, related electronic mail addresses, and the entire customers’ messages, together with non-public ones, up till May 2007.

SMS 2FA hardly a hurdle
One factor that stands out on this incident is that the attacker broke into the cloud internet hosting and source-code repository accounts of a number of Reddit staff although they use SMS-based two-factor authentication (2FA).
“Already having our major entry factors for code and infrastructure behind sturdy authentication requiring two issue authentication (2FA), we realized that SMS-based authentication just isn’t almost as safe as we might hope, and the primary assault was through SMS intercept. We level this out to encourage everybody right here to maneuver to token-based 2FA,” wrote Slowe.
Safety professionals have, in actual fact, suggested in opposition to utilizing textual content messages because the second issue as a result of their susceptibility to numerous threats. {Hardware} tokens and authenticator apps are more secure alternatives.
The positioning discovered solace in the truth that “the attacker didn’t achieve write entry to Reddit programs”. “[T]hey gained read-only entry to some programs that contained backup knowledge, supply code and different logs. They weren’t capable of alter Reddit info, and we’ve got taken steps for the reason that occasion to additional lock down and rotate all manufacturing secrets and techniques and API keys, and to boost our logging and monitoring programs,” stated the location.
