For social media professionals or search engine optimizers, Buffer is an important program, allowing users to schedule their social media blasts throughout the day in order to maximize the number of people seeing the update. For everyday social media nuts outside of the professional circuit, Buffer isn’t as relevant or as well-known, but that didn’t stop the application from generating breaking news headlines throughout the tech world this weekend.

According to a Tech Crunch report, Buffer’s systems were compromised by a hacker on Saturday morning and began blasting social media spam about weight loss programs rather than users’ regularly scheduled posts. But while many accounts – most of them professional – began spouting obvious spam messages like “Losing weight is easy with [product name]” or “I never thought I’d post this on Facebook, but I lost 15 pounds this weekend thanks to [product name],” Buffer higher-ups assured customers that personal data, including billing and payment information, remained secure during the cyber attack.

Naturally, Buffer noticed the spam problem fairly early on Saturday, and CEO Joel Gascoigne promptly tweeted a confirmation that Buffer had been hacked and that the tech team was working on finding a solution. Not all accounts were impacted by the spam attack, but all we affected when Gascoigne and the rest of the Buffer team pulled the plug on the posting service to resolve the issue.

Buffer users were undoubtedly bothered by the company’s hack on Saturday, with weight loss spam loading up their Twitter and Facebook feeds. However, if one good thing came out of the hack, it was that Buffer recognized its security weaknesses and rapidly made a point of addressing them.

An article published by PC World on Sunday indicates that Buffer has now encrypted its network access points to prevent hackers from entering the system through the same methods in the future. Gascoigne stated that the new security safeguards would allow for safer Twitter and Facebook posting and would give the Buffer team confidence and peace of mind that their system is now (mostly) hacker-proof.

Gascoigne also stated that Buffer was working with a number of cyber-security experts to determine exactly how hackers got into the system and took control of it so effectively.

Furthermore, the PC World article also revealed a number of statistics about the hack and the number of users it impacted. Out of some 476,000 Facebook accounts linked to Buffer, only about 30,000 – or 6.3 percent – were inundated with weight loss spam.
