Red Orbit: A Good Samaritan hacker has notified an app developer and the public of a vulnerability in the free messaging app WhatsApp that allows other app developers to access chat histories, rather than exploiting the flaw. Netherlands-based IT specialist Bas Bosschert offered details in a post on his blog, “Steal WhatsApp database (PoC).”
Bosschert and his brother were determined to answer the question “Is it possible to upload and read the WhatsApp from another Android application?” The short answer, “Yes, that is possible.”
“The WhatsApp database is saved on the SD card which can be read by any Android application if the user allows it to access the SD card. And since majority of the people allows everything on their Android device, this is not much of a problem,” Bosschert explains on his blog.
