California cancels aerial spray plans

The AP writes that plans to blanket urban areas with pesticides have been canceled due to advances in technology. A.G. Kawamura, state secretary of food and agriculture, claimed the shift to other plans was a natural progression, but the abruptness of the change seems linked to public protest:

Two counties and a Carmel-based environmental group sued the state, saying Kawamura broke state law by authorizing the aerial campaign without the benefit of environmental review.

Judges in Santa Cruz and Monterey counties this year halted the program until the state studied the spray’s effect on people and the environment.

In April, state environmental health experts said the illnesses reported after the first round of spraying couldn’t conclusively be linked to efforts to eradicate the dime-size Australian pest.

The race is on to control the moths without damaging the humans. Reminds me of all the usual debates about implementing security in ways that will not impact or impose restrictions on business. Strange that it took public protests and lawsuits to make this a meaningful issue for Kawamura.

Citibank admits breach of debit card server

Wired tells a sad tale of bank security in America:

A computer intrusion into a Citibank server that processes ATM withdrawals led to two Brooklyn men making hundreds of fraudulent withdrawals from New York City cash machines in February, pocketing at least $750,000 in cash, according to federal prosecutors.

The ATM crime spree is apparently the first to be publicly linked to the breach of a major U.S. bank’s systems, experts say.

“We’ve never heard of PINs coming out of the bank environment,” says Dan Clements, CEO of the fraud watchdog company CardCops, who monitors crime forums for stolen information.

They say this is a new page in security risks. However, when you read the Citibank brief there was a breach of a server that was most likely exposed to a partner’s security (7-Eleven). Accessing systems peripheral and partnered to the bank’s network is definitely a classic move. The rising number of interconnected systems (Wired points to this as real cyber-crime instead of traditional social engineering and physical attacks) means this risk is ever more present. Perhaps what is new is that the same guys who in the past might have just been satisfied to attack individual users now know how to target larger assets.

Encrypted Voice Breaks When Compressed

A security log entry by Schneier on eavesdropping compelled me to write a haiku:

Compress your bitrate
And expose the key to sound;
VoIP flows insecure.

I really like the attack vector he points us to. In short, when you compress voice on phone systems it creates a predictable key of sounds that can be used to unlock the encryption. In other words, sounds have patterns that the encryption does not hide. Even though the sounds themselves might be encrypted, they still have the appearance of known words and can therefore be guessed. For example “cow” will appear different, due to the length of the word when spoken, compared with “cat”. It might look something like ASDFADSFADSF versus ASDF.

Ok, second attempt:

Compress your bitrate
Hear the keys to sound exposed;
VoIP flows insecure.

McCain Drilled on Oil Money

Ha ha ha. This is a funny (or perhaps sad, but I’ll go with funny for now) commentary on Senator McCain’s position on energy reform. The Wall Street Journal blog exposes a serious concern for voters:

As McCain was talking about his energy plans, a protester in the audience at Missouri State University yelled out that McCain had accepted a half million dollars this year from “big oil.”

“That’s more than any other senator!” he yelled. “How can you be trusted?”

After the event, McCain was asked in a news conference if that were true, though the questioner mistakenly quoted the protestor as saying McCain took in a half billion dollars.

“I don’t know what he’s talking about. So I can’t respond,” he said.

Indeed, McCain does lead all other senators, and all others who ran for president, in contributions from the oil and gas industry, according to the Center for Responsive Politics’ analysis of federal data in the 2007-08 election cycle. McCain collected $724,000 through May.

This is more than double the amount his competitor has collected. It is little surprise that the energy industry lobbies candidates and pays heavily for government protection. The problem is McCain claims to be ignorant of his relationship with oil, and yet is aggressively calling for expanded drilling. When it comes to security, pro-BigOil policies usually mean bad news for America, so I expect a candidate to take a stand on energy reform that puts oil in perspective. This news shows McCain could decide to undermine his own country for personal financial gain.

Updated to add (June 20, 2008), an article by US News has California Republican Governor explaining the issue nicely:

“We are in this situation because of our dependence on traditional petroleum-based oil,” Schwarzenegger said. “The direction our nation needs to go in, and where California is already headed, is toward greater innovation in new technologies and new fuel choices for consumers. That is the way we will ultimately reduce fuel costs and also protect our environment.”

Barack Obama, the presumptive Democratic presidential nominee, has also declared his opposition to lifting the moratorium on offshore drilling.

Kudos to Schwarzenegger for being so clear on this issue and advising how to manage the risks from a more balanced perspective.
