Arrancando la semana

[Gramos @gastonramos]

Era un viernes de verano, y en la semana habíamos ido con mi amigo Gastón a Legión de María. Sí... yo iba a Legión de María a los dieciséis años, o algo así. Gastón sacó el dato de ahí: el sábado era el cumpleaños de 15 de una piba que parecía que iba...

@durov attack explained

[Pavel Durov @durov]

Last night Apple briefly removed Telegram from the AppStore because a user had planted illegal porn in a public chat.

Telegram was restored within hours. But I want to explain what happened — to warn other app developers and help protect online communities from similar attacks.

Because Telegram quickly removes illegal content from public groups using all kinds of moderation tools, the attacker had to resort to a technical trick. He inserted AI-modified illegal content by editing an old message in an active group chat. As a result the content was effectively hidden from the group’s members, preventing them from seeing/reporting it.

The attacker was a takedown extortionist: someone who demands ransom from group owners in exchange for not targeting their communities. These extortionists use automated accounts to plant illegal content in public groups and then report it directly to Apple, attempting to trigger the removal of legitimate communities whose owners refused to pay them.

From a practical standpoint, illegal pornographic content in Telegram’s public groups is not a systemic problem. Our moderation is effective. The fact that attackers must resort to backdated, effectively invisible content and other technical tricks proves this.

⚠️ However, there are two important lessons here for app developers and online communities:

— Extortionists have found a way to manipulate Apple into overreacting. Apple removed Telegram from the App Store before contacting us. This creates a potential systemic risk for every mobile app that hosts user-generated content. If an app used by more than a billion people can be removed from the App Store without prior warning, any app can be.

— The tactics used by takedown extortionists are evolving, putting communities across social platforms at risk. Telegram has extensive experience identifying the tricks used by coordinated reporting gangs and protecting legitimate communities (even when doing so risks our own app being temporarily removed from the App Store). Other platforms may not be equally prepared.

Stay vigilant! ☝️

JUST IN: 🇷🇺 Russia charges Telegram founder & CEO Pavel Durov with "facilitating terrorism."

An international ​arrest warrant ​has been issued.

We made public the details of the attack for the security vulnerabilities patched yesterday. We also make some tools to help with the forensic investigation. Take a look in this post in our forum https://t.co/n1CLWZa9sv
