HFT Too Fast - Insider Trading?

The Federal Reserve recently announced there would be no tapering to its current bond buyback program. That kind of information can be hugely valuable for whoever can act on it first as bond prices would immediately be affected. It comes to no surprise that HFT systems tuned to media feeds would be able to react the quickest based on programmatic rules … but what if they were too fast?

Analysis has revealed an initial swath of high volume trades appeared at exchanges within 3 milliseconds of the 2p.m. announcement. What is troubling is that reporters with advance access to the news were maintained in tight conditions:

Breaking iPhone 5s Fingerprint Biometrics

Apple says of its iPhone 5, “All of it began with something perfectly simple: your finger. And now we’ve taken touch to the next logical place with Touch ID, the fingerprint identity sensor. Your fingerprint is the perfect password. You always have it with you. And no one can ever guess what it is.”

Well, nobody has to guess what it is. The Chaos Computer Club has demonstrated an ability to unlock iPhone 5s using a captured fingerprint. The break-in technique utilized high resolution images of the fingerprint on thin, moistened latex sheets. CCC’s spokesman says, “We hope that this finally puts to rest the illusions people have about fingerprint biometrics. It is plain stupid to use something that you can´t change and that you leave everywhere every day as a security token.” In images from Mudge’s Twitter feed, it would appear CCC isn’t alone in having fun with Apple’s fingerprint sensor. Of course, street thieves can do it easier by just cutting off your finger when they steal your phone.

CSAW CTF 2013 - MISC 100 "Black & White"

Okay … other than my dabbling for a measly 550 points, there were no other “live” participants from the OmniNerd team this weekend. The image you can’t see to the right is a white, 1024×186, .png file named chal.png (actual link). The file itself is the only information provided by the contest which was solved by 818 of the teams. Can you figure out how to find the embedded flag?

Bored this weekend? As an OmniNerd, try the various challenges on the 2013 CSAW CTF. (Leave a comment below and I’ll send you the OmniNerd login). There are puzzles of various difficulty for reverse engineering, exploitation, cryptography and many others. If nothing else, watch the scoreboard to see the cadets of West Point’s SIGSAC team destroy Naval and Air Force Academies.

CSAW CTF is a entry-level CTF, designed for undergraduate students who are trying to break into security.

General Motors Quality Failure

So I’ve never really been a fan of American made cars, the companies have been building an inferior product to Japanese and European models for decades now. But presently, I’m saddled with a 2008 Chevrolet Equinox. And at exactly 100,000 miles, it’s started having all sorts of problems (stuck sunroof, broken power locks, P0455 that won’t vanish with new parts, etc. etc.)

Its the most recent problem that really sealed the deal on absolute crap quality from Detroit. While driving, the radio system just started shutting things down … speakers and then the whole radio, followed by turn signals. And then after turning off the vehicle, it wouldn’t start. Went through the usual routine of attempting to jump the vehicle with a portable jump battery followed by another vehicle to no avail. Huh, maybe it wasn’t a dead battery but a bad alternator? A digital multimeter confirmed the Equinox’s battery was fine and held plenty of charge.

Is Private School Morally Evil

Slate featured an op-ed a few weeks back from Allison Benedikt that apparently ruffled some feathers. The subject? Is sending your kids to private school a morally draining effort in that society is no longer collectively improving itself as a whole? Are your kids better off at the cost of everyone else? She writes:

You are a bad person if you send your children to private school. Not bad like murderer bad—but bad like ruining-one-of-our-nation’s-most-essential-institutions-in-order-to-get-what’s-best-for-your-kid bad. So, pretty bad.

Whatever you think your children need—deserve—from their school experience, assume that the parents at the nearby public housing complex want the same. No, don’t just assume it. Do something about it. Send your kids to school with their kids…. Don’t just acknowledge your liberal guilt—listen to it.

Predatory HFT

Annnnnnd it’s here. High Frequency Trading has continued to stay off the public’s radar largely because most people 1) just don’t care and 2) don’t understand it. They should start caring. The software has already proven to beat humans on a general basis and has been the primary factor in traffic volume for more than half a decade. The original models were largely looking for trends and arbitrage opportunities but the newest algorithms … are exploiting each other. Analaysts have examined mini “spikes” and “crashes” and determined they occurred too quickly and corrected too quickly to be the result of humans. But those anomalies are different than HFTs in the past which tended to bandwagon with each other for similarity in their algorithms. The new models appear to be predatory, essentially anticipating the behavior of another algorithm and quickly shaping a market condition to trigger the prey’s activity in order to create artificial arbitrage.

Yongbyon Reactivated

It will only be a matter of months before North Korea starts leveraging their reactor for favors again. Imagery indicates the Yongbyon nuclear facility has been reactivated. The plant has had a troubled history with the world from being the target of a ’90s era preemptive attack in OPLAN 5026 to being the subject of six-party talks in the early ’00s for deactivation. North Korea has quite a history of using the plant as a means of trading its deactivation for concessions from the west. It is suggested that Yongbyon, although a lightwater reactor, could easily be changed for plutonium enrichment.

Basketball Diplomacy

Well … clearly the problem for the past sixty years of armistice (despite North Korea’s recent attempt to dissolve it) was a lack of Dennis Rodman. The former basketball player has recently completed his basketball diplomacy tour of North Korea, undoubtedly seeing the official script instead of reality. Clearly, the United States just needed to go there and see that everything was rainbows and butterflies all along. Now seemingly friends with the DPRK leadership, Rodman quips, “He has to do his job but he’s a very good guy …. If he wanted to bomb anybody in the world, he would have done it.” And then goes on to challenge President Obama, “Why Obama, are you afraid to talk to Dennis Rodman? You’re not afraid to talk to Beyonce and Jay-Z, why not me? Why not me? I’m pretty important now, right?”

Easy to be a minister for marriage...

Now I have a good amount of cynicism, but I was reading through random Interwebs’ kibble and found this gem: about becoming an ordained minister. Now, I find the Pastafarians to be humorous, but this one gave me enough of a chuckle that I thought to give some of my hard earned bones to it.But the statement at the bottom gave me pause:
p. These certificates are legitimate and your name will be added to the official registry of ordained FSM ministers.
p. So I checked with what the great state of Maryland would accept as a minister, to see if this was for real and they said:
p. _Maryland

United States to Engage Syria?

It wasn’t the more than hundred thousand people that the Syrian regime killed that led the world to care. Rather, it was the chemical weapons the government used against its people that spurred the United States to threaten an attack. They’ve had the weapons for decades but the allegations of using them internally are relatively new with “wash-out bombings” taking place to burn away the evidence. The UN Security Council appears to have balked at getting involved leaving the United States to consider, once again, going at it alone. Presently, the Obama administration has only made mention of utilizing standoff capabilities against the regime without a ground element as a means of enforcing a global ban on chemical weapons.

UN Security Council Reform

How many times does this have to happen?

Once again we have a dictatorship going mad and killing its own people in great numbers.

After the horrors of WWII, all the countries of the world got together and decided that wars should be prevented because they could collectively stop them.

The mechanism chosen was a resolution for the deployment of the combined forces of member nations, and no other military actions anywhere would be acceptable under the UN treaty (International Law).

In order to free itself from the complexity of making such decisions in an all member nation plenipotentiary General Assembly meeting, the member nations (in the usual UN manner) created a sub committee, the Security Council.

Is the DIY coming to you

After seeing articles about the “coming movement” and the way that chip companies are working to get into the market one must wonder if this is the wave of the future, and what that will mean. Ultimately it is simply a follow-on of the digital revolution, this part is simply giving a real world output to all that digital information that we have been gathering. Now, the intellectual property is really the only thing, it can be made anywhere. But alas that intellectual property is becoming free as well, companies cannot compete with the tens of thousands that are putting out designs. This is the real “revolution,” and it is still the digital revolution, and like previous “revolutions,” it will change how society deals with itself. Futurists are declaring that we will all have home printers. While a possibility, I would guess that more probable would be stores that specialize in making things. But we are only on the cusp right now.
I expect to see that like the digital revolution, this “maker revolution” is like the blogs of yesteryear, this will be pervasive for a bit, and then the amalgamation will begin (and already has begun) where truly good ideas will be (in an app sort of way) cleared for you to use…at a small cost. And the world will finally start moving back to where customer service and electronics will go together. Where your “service store” stands behind the quality of their goods (and allowed designs), lest their approval rating go down.

SAC Capital Investment Woes

SAC Capital is currently in a world of hurt. The major investment firm is being indicted for insider trading with the government originally seeking ALL of its billions as punishment despite having already settled some of the issues to the tune of a $600 million fine. At first, most of us will think, “Let ’em burn.” However, the amount of money borrowed, invested and leveraged by hedge funds as large as SAC have deeper implications (hedge funds control an estimated $2.25 trillion). Part of the reason the government was gunning for all of the firm’s assets is that profits obtained from “dirty money” are themselves dirty and therefore seizable. And that extends beyond SAC into the markets that have also invested in and profited from SAC (which is most of Wall Street). The rest of Wall Street’s traders are concerned, however, because as SAC’s traders are indicted, they may also subject to scrutiny for basically bandwagoning when the illegal behavior should have been obvious. The investigation isn’t scaring away all the investors, there are many that plan to continue riding the gravy train of SAC’s run of success.

Violence in Syria and Egypt Continue

Sooooo, the violence in Syria continues. The world has watched since March 2011 as rebels fought with the government. More than 100,000 people have died in that span according to the United Nations. Egypt saw the beginning of Arab Spring and had mass, violent protests, though things became relatively sedate, until recently. Everything has exploded in the country once again with what appears to be a coup over the elected government.
