Folding@Home – Joint The Fight Against COVID-19

Posted by Scott Holstad on May 8, 2020

Want to join the fight against COVID-19 & don’t know how cause you’re not a doctor, scientist, etc.? There’s a great way anyone can help. You can donate unused computing power from your computer to Folding@Home, a distributed computing project for simulating protein dynamics, focusing on disease research including COVID-19. “The problems we’re solving require so many computer calculations & the FAH software allows you to share your unused computer power, so we can research more possible cures.” (Distributed computing is defined on their FAQ.) Anyone with a computer can join at no cost except pennies on utility bills. F@H is also interested in multicore, multi-GPU rigs, though any computer is fine. I have a custom designed & custom built PC with an 18-core/36-thread i9-9980XE & multiple NVIDIA GPUs. I started folding Tuesday AM & my first Work Unit was done in 4 minutes. Since then, I’ve added two more rigs to form “TeamScott” (Join Me!) & I plan to add more. In 2+ days, I’ve done 61 Work Units for 72,806 points, putting us at 44,675 out 252,943 teams! It feels great to contribute & it will for you too. Anyone can participate along with organisations like Cisco, AMD, CERN, Intel, NVIDIA, Microsoft, etc. Go here: https://foldingathome.org/. Their FAQ, which is pretty helpful, can be found here: https://bit.ly/3dqxemk. Hope to see you there!

A Review of Fatal System Error

Posted by Scott Holstad on December 22, 2015

Fatal System Error: The Hunt for the New Crime Lords Who are Bringing Down the InternetFatal System Error: The Hunt for the New Crime Lords Who are Bringing Down the Internet by Joseph Menn
My rating: 3 of 5 stars

Fatal System Error is an absolutely scary as shit, totally frightening book about today’s hackers and their ties to the Russian mob and how billions of US dollars in terms of identity theft and credit card fraud make their way to the Russian Mafia through this new breed of hacker. The author is a technology journalist who is a decent writer and the book could have been good, and at times, is, but it has some major flaws as well. First through, Menn, the author, traces the lives and paths of new cybercrime fighters in America and Britain, Barrett Lyon and Andy Crocker, as they develop ways to defend against hacker attacks and ultimately carry the battle to them. What they find out and how they did it is shocking.

Lyon, a young California computer geek helped a friend’s company stop something called a DDOS attack (denial-of-service) in the early 2000s. This was fairly new and some hackers had figured out they could start using their computers and other people’s computers in what later became known as bots and botnets to flood a person or company’s single server with data requests, thus bringing it down and bringing it offline. They initially started doing this to offshore gambling sites, where there was majorly big money to be made, and they demanded “ransoms” of some $5,000, $10,000, $20,0000, and as time went by, as much as $200,000, payable in hours, or else these sites would be shut down on a big game day and these betting sites would lose many millions of dollars. One of these major gambling sites heard about what Lyon had done and hired him to quickly defeat a DDOS attack against its company, which Lyon did. The thing I don’t really understand, since this became Lyon’s thing and since the author made such a big deal about this for about half the book and made such a big deal about Lyon’s computer genius, is that it seems to me that Lyon merely obtained and later bought large server farms to build up bandwidth and capacity to defeat the DDOS attacks – and it worked. But that’s not genius! Anyone could figure that out! That’s just brute force defense. There’s no brilliant coding. There’s not even any brilliant networking. No virus traps, no Trojans, no sniffers, nothing. Just server farms. Okay, whatever. He started his own company, with the backing of a number of these gambling companies he was now working for, all offshore, and which he rather stupidly and naively didn’t realize were themselves criminals, er, US mobsters. So, he started his own business with mob money. At some point, he rats them out, loses his business, somehow survives, starts a new business, and discovers that the world of hacking has passed him by, as DDOS is a thing of the past and he has to catch up if he’s going to sell his security skills. Lyon at some point started tracking hackers though various networks, finding that many of them were Russian punks, just teens. As part of this investigation, he came into contact with an English policeman named Andy Crocker, who was doing the same sort of investigation, but on an official basis for his government. Simultaneously, though acting independently, the two began to move in on the “bad” guys, watching as they transitioned from basic hacking to DDOS ransom schemes, then to identify theft and credit card fraud, and finally to government-sponsored cyber attacks on other governments and multinational corporations.

Andy Crocker was a British policeman, former military, now working a national task force dedicated to eliminating Internet crime. As noted, he came across Lyon while researching these hackers who were also hitting British gambling companies. He traced them, like Lyon, to Russia and other Eastern European countries, such as Kazakhstan, Latvia, and Estonia. Like Lyon, he was able to trace the originators of some of these DDOS attacks to actual hackers and found out some of their true identities and locations. He actually traveled to Russia to begin a cooperative effort with the FSB and MVD to locate, arrest, and prosecute these Russian hackers. And although it took great effort and a hell of a long time, they got three of the prominent ones, all young kids who had done a hell of a lot of damage and were responsible for millions of dollars of theft and destruction. But they obviously weren’t the only ones, by far. There were thousands of others and these were low level hackers. They wanted to go after bigger ones. And to their dismay, they found they couldn’t. One they tried to get was the son of the province’s police chief and he was untouchable. The biggest, someone called King Arthur, who was allegedly making a million a day, was unknown and unreachable and was a god in the hacking world. They eventually found his country and he was also untouchable. Andy was told by everyone that no one could go after him. That no one could arrest him, sorry. Someone big was looking out for him. Crocker came to the conclusion that either the Russian mob and or, and more likely, the Russian government was using and protecting the big Russian hackers. It was depressing. In fact, after Crocker returned to England, the Russian prosecutor of these hackers who was so gung ho about prosecuting more Russian hackers was found murdered!

Another depressing thing was just how deeply into Russian society this world of hacking and cybercrime runs. Apparently, St. Petersburg is a monster crime haven. Apparently there’s a mob organization so big and so powerful and so feared that they brazenly run ads advertising their services and skills openly and offer a home to over 100 big league hackers, carders, virus makers, botnet owners, scammers, spammers, crackers, etc. It’s called the Russian Business Network (RBN), and although it’s theoretically merely a network provider, it’s widely thought to be a government-sponsored, mob controlled crime syndicate that is extremely violent, horrendously violent, and very dangerous. And there’s not a damn thing anyone can do about it. It’s completely protected. It seems that virtually everything seriously big, bad, and evil goes through the RBN. No one can penetrate it. It’s a god.

The book goes on to assert that the battle against hackers and cybercrime has essentially been lost. That those who argue that real-time, live use of credit cards is riskier than online use are insane and dead wrong (which is interesting, cause I just read a carding book by uberhacker and now-Wired editor Kevin Poulsen stating this very assertion the author’s denying). That over 30% of America’s credit card numbers, as well as Social Security card numbers and other forms of ID, are in the hands of the Russian mobsters. This book was written in 2010. I imagine if this was true then, it’s probably worse now. It’s depressing as hell. Still, the two times I’ve been victimized by credit card fraud and theft, it’s not been online; it’s been live use theft.

The thing that really irritated me about this book, though, was that the author relied virtually exclusively on these two “experts” (one of whom I question is actually even a real expert) to write the book. Shouldn’t he have sought out sources from CERT, the much maligned (in this book) FBI, Secret Service, FBS (since he went there), big name hackers (go to the source), white hat hackers, other security professionals, etc.? Why rely on two people who may have had five years of varying degrees of success in the mid-2000s, neither of which I’ve ever heard of, and I’ve heard of many major security professionals, when there are so many sources to choose from? It seems short sighted and it seems like you’re limiting your book and your readers’ educations and experiences. I don’t like it. But that’s what he chose to do, so that’s what I have to live with. Still, I dislike it so much, and I dislike the fact that he focuses so damn much of the book on one figure who focuses almost exclusively on a hacking technique (DDOS) that went out of style even before the mid-2000s, that I’m knocking the book down from four stars max to three max. This could and should have been a much better and broader book and it wasn’t. I think the author did the reader a grave disservice. Not a great book with unusual sources, but slightly recommended if you want to wake up sweating in the middle of the night.

I found a number of interesting reviews, one of which impressed me so much, that I’m going to print it here without the author’s knowledge or permissions, but while giving him full credit and hoping he approves. I think he makes some excellent points about the book and they’re worth reading.

One star

Thank goodness for Goodreads reviews and bookswap. Reading the prior reviews I had low expectations for this book, and through swap I only wasted money on the postage.
The book can almost be divided into 3 segments. The author seems to only have interviewed two main participants against internet crime, and came away with an incomplete and incoherent understanding of any details of the problem. He almost attributes all the evil on the internet as having a denial of service as the source. Even during the second part of the book, which included the topic of identity theft, he was attributing most of the theft activity to DDoS. I think he just like to bring up the acronym.
Some of the problems I had with the book :

1. There were 90 pages attributed to crimes of US mafia figures, in which the dollar amounts of each occurrence were laboriously spelled out like a Bob Cratchet accountant listing personal losses and moaning about the inability of the FBI to pursue the Gumbas and delegate justice. Literary style could have been extended to a two-page spreadsheet report detailing the who, how, and how much figures. This segment of the book generated the feeling of watching a Godfather marathon movie session, and I felt really diverged from the intent of discussing internet crime in terms of how the internet is the enabling tool. I already suspected that mules carry money, people get killed, and identities are just handles to hide behind.

2. The swashbuckling crime fighting DDoS buster had a girlfriend to whom a few pages were wasted on. Since she was irrelevant to the overall topic, she could have been mentioned once for background, and not introduced as what might have become a significant character (but never did).

3. The mechanics of defeating a DDos attack were never detailed. The server farm set up in Phoenix had the bandwidth and number of servers to defeat an attack, but there were no details provided as to why it was specifically set up in Phoenix, what its components were, and how a direct attack defense was managed.

4. Because the author seemed obsessed with DDoS, he mentioned bots and botnets at least once on every 3rd page. He never described a bot to the laymen. He never made it clear whether a bot could consist of a virtual machine created for a purpose, or whether it had to be an independent 3rd party box belonging to an unsuspecting bystander. The author never fully explained the mechanics of a trojan horse implant, and didn’t clarify the difference between a virus and trojan horse. He also never explained what can be done at the individual user level to fend off trojans and viruses, except in a short subject dealing with phishing emails generated by spam during — DDoS attacks. He never clarified that DDoS isn’t necessary for phishing, and neither are bots.

5. Only once was it mentioned that one group switched to Macs because they seemed less susceptible to attack. He mentioned at least twice that you can’t sue Microsoft for providing a faulty OS combined with a poorly updated integrated browser, because purchasing a machine with Windows provides only a license to use the software and provides no firm sale transaction in which a person owns the software running on the hardware that they do own. He did mention the Microsoft monopoly on the OS, but failed to mention that Microsoft was prosecuted in conjunction with monopolistic powers only related to installation of a browser. It was never mentioned that Microsoft to this day controls hardware vendor access to Windows, and if the hardware companies dare install anything else but Windows or MS products, they will be heavily penalized in regard to being able to install Windows. If anyone says the Dell sells Linux, I must say that I’ve only ever been able to find minimal hardware boxes in the very basic desktop configuration, and in selecting one of those choices, there is a radio selection button for the OS that would full form advance to a Windows selection. Phone inquiries were even worse at the individual customer level. Only institutional server customers could purchase equipment with Linux pre-installed. Same story at all vendors except Lenovo, and then only through individual providers.

6. The author in the last 50 pages provides a conglomerated synopsis of headline events and trends regarding contemporary internet warfare across national borders. China is mentioned as a war opponent in cyberhacking, but it is never mentioned that China manufactures a significant volume of the circuitry used in electronics and could very easily, using the subversion techniques described by R.J. Pineiro, hide logic bombs and covert data skimmers within circuit boards and components. This could happen to Apple and all the phone manufacturers, so that their equipment could be subverted despite the installed software. Of course the title of the book was “the hunt for the internet crime lords”, so hardware subversion might have been beyond the scope.

7. Since the title was the “hunt for the New Crime Lords who are bringing down the internet”, some credit must be given to the author for remaining in the hunt venue, and not providing the extraneous technical details that readers might be led to expect by the book-cover blurb adulations such as “A fascinating high-tech whodunit”. The high tech here would be synonymous to an interstate highway providing speeders the ability to go faster.

8. The middle segment dealing with a physical legal pursuit presence in Russia, was in my opinion the redeeming revelation of the book. Life in Russia has never been painted as a Disneyland experience, but the adverse conditions both politically and physically presented here, really underscored the futility of pursuit of Soviet area bad guys in their home territory.

A Review of What The Dormouse Said

Posted by Scott Holstad on February 21, 2015

What the Dormouse Said: How the Sixties Counterculture Shaped the Personal Computer IndustryWhat the Dormouse Said: How the Sixties Counterculture Shaped the Personal Computer Industry by John Markoff

My rating: 4 of 5 stars

This book was a fascinating history of personal computing in America, most specifically in Northern California, most especially in the Stanford region. I swear, I had no idea that Stanford played such a strategic role in the development of the personal computer.

The book attempts to tie together nerdie engineers with counterculture LSD druggies with free love types with antiwar activists with students with hackers and the mix is considerably hard to pull off, even for a writer as accomplished as Markoff. In fact, I would say that he fails at it. Still, he tries, yes, he does. He tries a chronological approach to things and soon we have computer science engineers dropping acid in what will become Silicon Valley, leading to who knows what kinds of creativity. But Markoff really concentrates this book on two or three people: Doug Engelbart and his Augmented Human Intelligence Research Center at SRI (Stanford Research Institute) and John McCarthy’s SAIL (Stanford Artificial Intelligence Laboratory). Another important figure is Stewart Brand, author of the Whole Earth Catalog. Finally, there was programmer extraordinaire, Alan Kay.

Engelbart had a vision and he pulled in people to create his vision. He envisioned a computer — this was the 1960s — that would augment how people thought and what they did. McCarthy also envisioned a computerized world, albeit a slightly different one. Brand envisioned a computer for every person, while Kay envisioned small computers — laptops of today — that were so easy to use, that small children could be taught to use them. And these men all pulled it off!

Engelbart plays such a large role in the book, that it’s nearly all about him, and I think that does the book a bit of a disservice. Nonetheless, it’s he who creates the mouse to use with a display and keyboard in the late ’60s. He was funded largely by ARPA and was critical in the development of the ARPAnet, the precursor to the Internet.

At some point, the book shifts to Xerox PARC (Palo Alto Reserch Center), the infamous Xerox research facility that had the most brilliant geniuses of the twentieth century under one roof and who literally did invent the personal computer as we know it to be. This was before Steve Wozniak and his famous claim that he invented the personal computer. Under Bob Taylor At PARC, Kay and the others who had shifted over there invented a graphical user interface, an operating system, a text editor (word processor), programming language, software, Ethernet for networking, a mouse, display, keyboard, audio, and a laser printer, which would be the only thing Xerox would go on to make money with. Xerox was so stupid, they never realized what they had in hand and they could have owned the world, but they didn’t. Stupid, stupid, stupid.

Markoff weaves various stories of people like Fred Moore throughout the book, attempting to capture the counterculture spirit, but it seemed a little lost on me. Most of the techies weren’t overly political. Most avoided Vietnam by working in a research facility that did weapons research (SRI). Most dropped acid at some point, but very few seemed to make that a lifestyle choice. I thought it was an interesting book, as the topic is personally interesting to me, but it wasn’t the most cohesively written book and I would have expected a little more from a writer of Markoff’s stature. Still, four solid stars and recommended.

Windows 8.1 widens gap with older PCs

Posted by Scott Holstad on June 27, 2013

Review: Windows 8.1 widens gap with older PCs – Yahoo! News.

“So, instead of bringing back a familiar environment, the revived “Start” button is mainly just another way of directing you to the new one.”

That seems to defeat the purpose, doesn’t it?

I have a Windows 8 machine and I don’t understand the fuss. The Start screen is intimidating at first, and I think it’s a bit overrated, but you can get your old Desktop screen with one touch, so what’s the big deal? And you can get to all of your apps from that Desktop screen, so again, what’s the big deal? If you don’t like the Start screen, simply use the Deskstop screen and you’ll be OK.

The app store, however, is just silly. There’s aren’t enough apps, and especially enough good apps — and free apps — to justify its existence. Well, I guess it needs to exist, since that’s how I’ve gotten several apps, but I’ve had to purchase most of the programs that I use and download them from Amazon or Microsoft (ie, MS Office 2013), so there’s that.

I got a touchscreen computer cause I think it’s the wave of the future and I didn’t want to regret not getting one two years from now. But I think I may have jumped the gun, since I tend to use my mouse most of the time. At some point, using touch may be mandatory, but for now, it’s not essential.

I kind of like Windows 8. I think it’s Microsoft’s biggest jump in its operating system since they created Windows and moved people from DOS (the good old days). It’s not a bad concept. Microsoft just needs to iron out some kinks and get people used to it.
