My other half discovered that some dodgy person/company had managed to send instagram messages to all of her followers from her account. She changed her password immediately, but what could have happened here? Is it the case that a “hacker” had access to her full instagram account, or would they have used some tool that allows posting of messages via some kind of proxy without requiring access to her actual account? There was no record of other logged in devices on the security page of her account.
Most likely it was a password stuffing attack. If they used the same password on multiple sites, there is a good chance one of those other sites was compromised and the attackers took the compromised credentials and tried them on other sites like Instagram. It could have been something more advanced like a stolen cookie, but usually the simplest explanation is most likely.
Always use a different password for each service, enable MFA where possible, and use a password vault like Bitwarden.
yup, all mine are generated by bitwarden and look like this
