During a generic inspection, I noticed a few unfamiliar open ports on a client.

A few minutes later I had root access on a HOT modem, enabling me to control its routing tables, tunnels, etc.

A couple more C class scans later, I realized this vulnerability affects ~80% of HOT’s home networks. These networks are managed by an Ambit Wireless Router/Cable Modem, which had “built-in” security holes.

After consulting with my trusted friend (and lawyer) Effi Fuks, we contacted HOT’s CISO, in attempt to help them fix this issue across the board.

Digital Evidence @ Digital Whisper

Sat, 31 Jul 2010 17:24:00 +0300

The editor of DigitalWhisper sent me an email asking if I’ll be interested in writing for his journal. I focused on the recent work I had done with Effi Fuks in regard of Digital Evidence and validating E-Mail correspondence as part of a legal case/process.

This was my first attempt in writing a technical article in Hebrew, comments would be welcomed :)
