A Note on Security from Instagram’s CTO
By Mike Krieger, Instagram Co-Founder & CTO

care deeply about the safety and security of the Instagram
community, so we want to let you know that we recently
discovered a bug on Instagram that could be used to access some
people’s email address and phone number even if they were not
public. No passwords or other Instagram activity was revealed.
We quickly fixed the bug, and have been working with law
enforcement on the matter. Although we cannot determine which
specific accounts may have been impacted, we believe it was a
low percentage of Instagram accounts.
of an abundance of caution, we encourage you to be vigilant
about the security of your account, and exercise caution if you
observe any suspicious activity such as unrecognized incoming
calls, texts, or emails. Additionally, we’re encouraging you to
report any unusual activity through our reporting tools. You can
access those tools by tapping the “…” menu from your profile,
selecting “Report a Problem” and then “Spam or Abuse.”
Protecting the community has been important at Instagram from
day one, and we’re constantly working to make Instagram a safer
place. We are very sorry this happened.
