A hack appears to have affected a number of Instagram accounts, with affected accounts displaying a rogue photo of a smoothie alongside a comment telling users to visit a website for more information on that smoothie. The hack first appeared late July 26.
"Last night a small portion of our users experienced a spam incident where unwanted photos were posted from their accounts. Our security and spam team quickly took actions to secure the accounts involved, and the posted photos are being deleted."
Instagram released a response on July 27.
Instagram Users Say They Are Being Attacked By Delicious Smoothies (Updated With Instagram's Response)
The Instagram smoothie hack is similar to an incident that occurred in late June, in which spammers uploaded photos of fruit to users' profiles. No one has taken responsibility for either hack, nor has any technical explanation been given for how they were carried out.
Beware: a massive (fruity) spam attack is hitting Instagram
"Got hacked on @instagram. Wtf. pic.twitter.com/m6we1Z0RCE"
Olanoff, who works at Yahoo— and TechCunch before that— posted a photo of the smoothie on July 26. Several other people posted on Twitter that they have also been affected by the hack, many saying they don't recall clicking on suspicious links or giving away their passwords.
