‘Evil twin’ fear for wireless net

Here is an interesting article from the BBC site about fake Access Points.

Something similiar on Wi-Fi Networking News

“People using wireless high-speed net (wi-fi) are being warned about fake hotspots, or access points.

The latest threat, nicknamed evil twins, pose as real hotspots but are actually unauthorised base stations, say Cranfield University experts.”

It is very interesting to me as this is precisely what I’m trying to do at the moment on the SEINIT project where I work. I’m currently trying to put together a wireless linux distribution and the plan is to add Intrusion Detection (IDS) functionality. Part of that functionality would be to assume the Identity of Access Points that are being attacked in order to ‘lure’ an attacker into attaching to the ‘fake’ access point. Unfortunately I’m still fighting with a CF to IDE adapter :(.

Sunday papers and stuff

I was in Clonmel yesterday visiting the folks, got my Dad to help me with a small wiring issue with my car.

I’m planning to have two Radio Transcievers in the car one dedicated to Tracking (APRS) and one for Voice communications. If I was unfortunate enough to hit maximum current draw on both at the same time it would require over 30Amps to power them. So yesterday we ran a dedicated cable out to the Battery. It should be safer than putting that much current through the loom in the Car.

Anyway, the point is I forgot to read the papers. And this morning I spotted Sunday Snippets and Jeremy Clarkson on A380 (from the Sunday Times) on Bernard Goldbachs weblog. I’ll take these as the highlights of the weekend 🙂

Scott eVest

I flew to London Tuesday evening for a SEINIT project meeting in UCL on wednesday. I walked down to Borders and grabbed a few American Amateur Radio/Scanning magazines. I like to get them now and again as, compared to here (Ireland/UK), there are many many more “HAMS” in the US than here, so its a much bigger and more varied market. Anyways, I was reading the “What’s New” section of the Monitoring Times magazine on EI723 back to Cork, and I spotted an add for the Scott eVest, now with a solar panel, just what a geek with gadgets would need :). Very cool!

MD5 To be considered Harmful

I got this link from Slashdot. To summarise “….But the risks are real enough that responsible engineers should take note: This is not merely an academic threat, systems designed with MD5 now need to take far more care than they would if they were employing an unbroken hashing algorithm, and the problems are only going to get worse.”

Here is the source site. Some good stuff on here. I particularly like using DNS for one-to-many streaming data dissemination, in fact the whole ‘DNS tunneling’ area is very interesting, well worth coming back to I think.

Speeding excuses

Saw this on the reg.

“The Northumbria Safety Camera Partnership, aka “Safe speed for life” has just published its top 10 excuses for geting nobbled by a speed, sorry, safety camera. Top of the list is alien-induced trance, closely followed by blaming excessive velocity on a passing aircraft. The list is culled from the letters received by fixed-penalty units in which motorists attempt to extricate themselves from copping a fine for speeding.”

Canary Wireless

I saw this in the Wi-Fi Networking News. Very cool piece of kit. Unfortunately its not CE approved yet (who cares). An external antenna connection “May” be included in future versions of the product. Sounds good to me!
