GOTCHA: Taking phishing to a whole new level

Why X-FRAME-OPTIONS matters on API endpoints As a security researcher, I try to identify area’s of potential abuse before bad people do. Once in a while, you stumble upon an attack scenario that is so incredibly stupid yet genius at the same time, that it deserves a name and a…

Abusing autoresponders and email bounces

Being a bug bounty hunter, I face a lot of competition. Lots of companies are willing to issue rewards for vulnerabilities in their systems, but only if they haven’t been reported by someone else. If you want to beat the odds of finding duplicates, you better look for bugs in…

OPINION: It’s too late now to say sorry, Mark Zuckerberg.

Last night, a member of British parliament released hundreds of pages of internal Facebook e-mails. The documents shine a light on Facebook’s aggressive growth strategy and its willingness to sacrifice its user’s privacy over business decisions.

Interactief quizzen in Instagram Stories? Studio Brussel testte het uit!

Eerder dit jaar pakte Burger King uit met de allereerste interactieve story op Instagram. In een reeks polls konden de volgers van de hamburgerketen hun persoonlijke burger samenstellen. Meteen daarna kreeg je als deelnemer een privé-bericht (DM) met een unieke code waarmee je je creatie kon afhalen in een restaurant.

OEPS: Dit verklapt Facebook over de afloop van Temptation Island

Vorig jaar konden we via Instagram achterhalen dat Lize en Ken uit Temptation Island een stelletje vormden. Ze werden door VIJF en RTL5 snel op de vingers getikt, want contractueel mogen ze tussen opnames en de laatste uitzending niet samen gezien worden. Ook niet op sociale media. VIJF lijkt dit…

Wat we met Studio Brussel leerden uit de metal-logo-bot op Facebook

We houden allemaal van dingen waar onze naam op staat. Souvernirwinkeltjes puilen uit van de sleutelhangers, drinkbekers en sieraden met onze voornamen op. Nutella en Coca Cola hebben die voorliefde ook goed begrepen en verwerken daarom al jaren voornamen in hun verpakkingen. Naar de mijne blijft het voorlopig zoeken.
