A social hangout website for teenage girls has sprung a leak that's exposing plaintext passwords protecting as many as 5.5 million user accounts. As this post went live, all attempts to get the leak plugged had failed.
Operators of i-Dressup didn't respond to messages sent by Ars informing them that a hacker has already downloaded more than 2.2 million of the improperly stored account credentials. The hacker said it took him about three weeks to obtain the cache and that there's nothing stopping him or others from downloading the entire database of slightly more than 5.5 million entries. The hacker said he acquired the e-mail addresses and passwords by using a SQL injection attack that exploited vulnerabilities in the i-Dressup website.
The hacker provided the 2.2 million account credentials both to Ars and breach notification service Have I Been Pwned?. By plugging randomly selected e-mail addresses into the forgotten password section of i-Dressup, both Ars and Have I Been Pwned? principal Troy Hunt found that they all were used to register accounts on the site. Ars then used the contact us page on i-Dressup to privately notify operators of the vulnerability, but more than five days later, no one has responded and the bug remains unfixed.
I want to draw your attention to some great work Dr. Bontchev did.
pcodedmp.py is a VBA P-code disassembler. Microsoft Office documents contain VBA macros in several forms. They contain the source code, but also compiled P-code. Dr. Bontchev created a proof-of-concept document that executes P-code and does not contain the corresponding source code. Here is the output from his pcodedmp.py tool for his PoC document:
python pcodedmp.py -d poc2b.docProcessing file: poc2b.doc===============================================================================Module streams:Macros/VBA/ThisDocument - 1949 bytesLine #0: FuncDefn (Sub / Property Set) func_00000078Line #1: LitStr 0x001D This could have been a virus!

Dr. Bontchev also coded a plugin for oledump.
