| Exploit uses firewalls to hijack smartphones, turns friends into foes May 22nd 2012, 07:18  Normally, firewalls at cellular carriers are your best friends, screening out malware before it ever touches your phone. University of Michigan computer science researchers have found that those first lines of defense could be your enemy through a new exploit. As long as a small piece of malware sits on a device, that handset can infer TCP data packet sequence numbers coming from the firewall and hijack a phone's internet traffic with phishing sites, fake messages or other rogue code. The trick works on at least 48 carriers that use firewalls from Check Point, Cisco, Juniper and other networking heavy hitters -- AT&T being one of those providers. Carriers can turn the sequences off, although there are consequences to that as well. The only surefire solution is to either run antivirus apps if you're on a mobile OS like Android or else to run a platform that doesn't allow running unsigned apps at all, like iOS or Windows Phone. Whether or not the exploit is a serious threat is still far from certain, but we'll get a better sense of the risk on May 22nd, when Z. Morley Mao and Zhiyun Qian step up to the podium at an IEEE security symposium and deliver their findings.

Did you go but want to relive the experience a little? Well look no further: we came, we saw, we conquered. As one of our friends acutely observed, you couldn't throw something this year without hitting a 3D printer. Below you'll find pictures of said 3D printers, but also unicorns, Tesla coils and yes, even zombies (!) -- all lovingly curated from the hundreds of shots we took at the event this past weekend. Craving something with a bit more meat? We've made a convenient list of our Maker Faire posts. Once you're done digesting that, hit the break for our lovely video montage.

Both of the complaints have a common proposal that would see Dish give up 20MHz of its 40MHz space in the 2GHz range to prevent the satellite giant from using its abundant airwaves as part of a cash grab: MetroPCS and T-Mobile are worried Dish will just try for a "windfall" and sell the spectrum it doesn't need to AT&T or Verizon. While it's not asking for a sell-off, the Rural Cellular Association is still jittery about concentrations of power and wants the FCC to make Dish hit certain build-out targets, offer roaming at wholesale rates and require FCC approval for any roaming deal that would go to Big Blue or Big Red. The big carriers' advocacy group, the CTIA, is unsurprisingly against build-out demands as "unduly burdensome." FCC officials have been silent by comparison, although the agency has encouraged spreading spectrum around and proposed its own expansion requirements. You'll likely see smartphones with 2GHz frequencies at some point in the future -- it's just a matter of whether Dish or someone else slaps its logo on top.
