Hackers are inserting "sexual videos" into the walls and profiles of your Facebook friends. See Example( s )
Collected via e-mail, November 2011
In September 2011, warnings about hackers invading the accounts of Facebook users to post pornographic movies on their walls without their knowledge began circulating in e-mail and on social networking sites. These messages usually contained cautions meant for friends of those users to avoid “opening” (clicking links to) those movies and to avoid “voting” on any proffered picture sent via the same channel.
We’ve yet to encounter any verified account of “hackers” having surreptitiously inserted “invisible” risqué films into the Facebook accounts of innocent users, posts which those users cannot see but are visible to their friends. Sometimes images that appears to be links to pornographic videos show up in compromised Facebook accounts, but those posts are clearly visible to the account owners. Folks who are therefore using social networking sites prudently should not fear they’re about to unknowingly begin issuing porn video come-ons to their friends and family.
A new variation appeared in 2016. In this case, the hapless user still cannot see what is being spread on Facebook in their name, but instead of pornographic videos, it supposedly spams Facebook contacts with offensive and insulting comments (that the user still cannot see). While this variation is also not real, it can perhaps serve as a reminder to periodically change and update passwords to social media sites.
