Interesting! This Kevin Day guy comes up in Google in various security/password/hacking links. The plot thickens!

If he is the hacker then hopefully he will be eventually found guilty by a just court based on actual strong evidence.

So fucking what? My name does too.

Hey Kevin Day.....

Are you the same Kevin Day that wrote the Book, "Inside the Security Mind" "Making the Tough Decisions"
http://www.amazon.com/Inside-Security-Mind-Making-Decisions/dp/0131118293

From the Back Cover

    "This is a really good book ... it spells out the motherhood and apple pie of information security in a highly readable way."

—Warwick Ford, CTO, VeriSign, Inc.

    "An excellent security read! Breaks down a complex concept into a simple and easy-to-understand concept."

—Vivek Shivananda, President

    Redefine your organization's information security
    Learn to think and act like a top security guru!
    Understand the founding principles of security itself and make better decisions
    Make your security solutions more effective, easily manageable, and less costly!

Make smarter, more informed security decisions for your companyOrganizations today commit ever-increasing resources to information security, but are scarcely more secure than they were four or five years ago! By treating information security like an ordinary technological practice—that is, by throwing money, a handful of the latest technologies, and a lineup of gurus at the problem—they invariably wind up with expensive, but deeply flawed, solutions. The only way out of this trap is to change one's way of thinking about security: to grasp the reasoning, philosophy, and logic that underlie all successful security efforts.

In Inside the Security Mind: Making the Tough Decisions, security expert Kevin Day teaches you how to approach information security the way the top gurus do—as an art, rather than a collection of technologies. By applying this discipline, your solutions will be more secure and less burdensome in time, expense, and effort. The first part of the book explains the practice of breaking security decisions down into a set of simple rules. These rules may then be applied to make solid security decisions in almost any environment. In the second part, Day uses a series of practical examples to illustrate exactly how the discipline works in practice. Additional material covers:

    Designing an enterprise security plan, including perimeter/firewall and Internal defenses, application, system, and hardware security
    Ongoing security measures—recurring audits, vulnerability maintenance, logging and monitoring, and incident response, plus risk assessment
    Choosing between open source and proprietary solutions; and wired, wireless, and virtual private networks

This book is essential reading for anyone working to keep information secure. Technical and non-technical IT professionals alike can apply Day's concepts and strategies to become security gurus, while seasoned practitioners will benefit from the unique and effective presentation of the essential security practices.

So its just a huge coincidence that the same guy cashing out would be involved in security of the sorts mentioned in this thread.

Fuck if this is all just some serious coincidence then Kevin should just get of the internet, there is a very good possibility of a ricochet bullet hitting him via the interwebz.

I actually think Kevin's story makes some sense.  I still think he should return the BTC he withdrew (or forfeit the $3000 and all remaining BTC in account to cover the loss, which, as he claims, is probably worth close to $10,000 at market prices).

Kevin says (1) he has a higher withdraw limit than $1000 and (2) he withdrew around 600 BTC.  It is true that his post implies that his limit was at $1000 when he withdrew, but I don't think that's actually the case and I don't think that he meant to imply that.  Many on the forums have claimed that the BTC withdrawal is based on a 24-hr rolling average (people who claim to have hit this limit themselves, presumably when trying to withdraw during recent volatile periods) and not on the current market price.  At that point the 24-hr rolling average was apparently around $4.5, which would have allowed a maximum withdrawal of around 200 BTC per $1000 allowed.  600 BTC withdrawal, then, aligns with a roughly $3000 withdrawal limit.  I think perhaps he assumed that the limit was based on $0.01, but was in fact wrong about that.

But, like I said, I still think he has no claim to profit on the buy-side of a fraudulent sell order.

I am noticing the same questions being asked of both parties and not being answered.

Question: Who do you believe, the person who has 250k bitcoins to lose (kevin), or 500k bitcoins to lose (MtGox)?

Answer: Neither.

Good call!

I believe that actually Kevin doesn't have to give back any of it.
He purchased them in good faith. Even if the market was crashing, I would have purchased it if I saw the opportunity.

• Now, even if it is on his right to keep them, IF the money belonged to MTGOX (and not a user, but actually the main fund of MTGOX, which seems to be more plausible the more I think) then I guess that for the betterment of the economy and its stability, Kevin should give it back to MtGoX.
  In exchange of the devolution, MtGox should give a compensation for the act of good faith and allow Kevin to keep the withdrawn amount
• If the account was a personal one, Kevin has less obligation to give it back to the owner of it. When you make the wrong call playing poker you can't undo it, if you fucked it up, you fucked it up. Period.
  But still, it would be a nice gesture, and this would be totally from Kevin's generosity, if Kevin gives back partially or totally to the previous owner. A generous compensation for this gesture would be appropriate.
  

BUT, Kevin has all the rights to keep it and not giving it back to anyone. He would be a total asshole by behaving like that, but it is in his right.
Now, everything depends on his will.

MtGox shouldn't rollback shit.
The least thing that MtGox can do is to compensate to all users for this scandal and for they negligence/incompetence.
The leaked userbase is embarrassing enough, and that needs a fair compensation to all of us who entrusted this site with our money, and in some cases, our life savings (doesn't matter if trusting one's savings is a unsound judgement, the point here is that our trust has been broken).

It takes decades to build trust, and only one second to break it.

Usually, one never recovers full trust with a person, but doing good deeds can help to reestablish the relationship.
I hope MtGox understands here that more than profit, trust is actually the backbone of a business.
If you don't offer a deal to keep your users happy, expect a bank run.

(Wrong thread, I wanted to post it in Kevin's thread...)
