Found it on the Webs / The 2015 SANS Holiday Hack Challenge
« on: December 12, 2015, 12:26:48 pm »

There is a holiday hacking challenge at https://www.holidayhackchallenge.com/

I checked it out and it's like a Pokemon game combined with some hacking challenges! It's really awesome, so I wanted to share it here! Now I'm going back to the game, I have to find out some hot chocolate to get some info about a pcap file from an NPC  ;D

News and Announcements / Re: Board restrictions to new members
« on: September 23, 2015, 01:10:09 pm »
I totally agree with this idea, especially since I'm lazy and most of the time I need a whip or a carrot on a stick to make me do something when I can always postpone it for later (which turns really fast into never).

Also, imo, there is nothing wrong with being elitist, as long as it's on a non-jerk scale. This term has a bad rep because of all the idiots using it to be rude to other people, but you can still demand quality or meeting certain criteria from your users / members etc. while remaining newbie friendly. 

Since the ebooks section is probably the most popular and sought after, I think it's only logical to restrict access to it, and 20 posts is almost nothing compared to the gain of being able to instantly download all those books, without going to shady shortened URLs or navigating through dozens of ads on a hundred different sites.

Operating System / Re: To all the people running Windows 7 and 8.
« on: September 18, 2015, 12:19:47 pm »
You can avoid it being downloaded to your machine if you don't install the updates that are *supposed to make upgrading to Win 10 easier*.  If you don't want to install Win 10 you have no need for them, and along with shoving Win 10 to your face, they are also backporting some of the privacy invading shit to Win 7 and 8.

You can verify if you installed the  updates by checking if you have this hidden folder in your system drive: $WINDOWS.~BT  (this is where Win 10 gets downloaded to). If you delete it without uninstalling the updates, it will just get recreated.

I didn't run into your problem, but I recommend you use Win XP for these tutorials, I started on Win 7 but then switched to XP when some programs wouldn't work properly on 7.

Lena's tutorials are awesome, that's what I'm going through at the moment and I can say I've learned a ton. They are a great example of what you can learn by doing instead of reading ( not that reading is bad, but in my case, I've had best results with practical learning).

You can find Random's tutorials along with other guides and tutorials here: http://octopuslabs.io/legend/blog/sample-page.html

Tiga's video tutorials on Ida is also a good series: http://www.woodmann.com/TiGa/idaseries.html

Beginner's Corner / Re: Learning Python to Hack
« on: August 12, 2015, 12:59:55 pm »
I see that Violent Python is not in your list for hacking-with-Python books. I strongly recommend you read it, it's an excellent book with lots of code samples and explanations for various security and hacking related topics. It's by far my favorite book for how to use Python for penetration testing.

General discussion / Re: Kendo techniques
« on: August 11, 2015, 08:09:52 pm »
If possible, I recommend finding a dojo where you can learn kendo...receiving formal instruction is important, especially at beginner level (that applies to all martial arts). I think it's best to have a teacher in disciplines that might cause physical injury if improperly applied / learned. Nevertheless, training alone isn't impossible, it's just harder and riskier in my opinion. Also, from personal experience, since I've always been interested in swordsmanship but didn't have the chance to learn it from somewhere, I practiced some things alone, from descriptions or videos. I started doing suburi (the basic move in kendo) with a  suburito (that's like a short, thick stick used for doing suburi, and much heavier than a normal shinai or bokken), and also tried to imitate what I've seen in a dojo that I've visited. But I thought..starting gradually is boring, why don't I do 1000 every day? So I did...until after a few weeks I had to stop because of an injury, which ironically, is common in kendo, especially if your technique when doing suburi is wrong. So if you do start training alone, I advise to go for steady, gradual progress, to minimize the risk of injury.

About Musashi and the other swordsmen who learned by themselves, they are an example that it can be done. However, those times were different, and samurai as dedicated as Musashi probably spent their whole time just training and thinking about the sword, and testing things out. Those were days when their survival depended on their skills..in our age we can't dedicate that much time to training with a weapon that is no longer used in combat, so our progress wouldn't be as good as theirs.

The KendoWorld forums and youtube channel are a good place to start informing yourself about kendo. Also, I've found the youtube channel of a Japanese sensei called Hiro Imafuji quite helpful and easy to understand for a beginner.

And by the way, kendo is a more modern version of Japanese swordsmanship, and it's not exactly what the samurai used in combat, which was referred as kenjutsu. Musashi's Ni-Ten Ichi Ryu and other styles are all forms of kenjutsu. Kendo evolved from that to become what it is today.

General discussion / Re: Miyamoto Musashi

Musashi is also one of my favorite historical warriors as well. I've read several translations of his book, Go Rin no Sho, and tried to get my hands on whatever books about his life and accomplishments were available. I have a few of them in pdf form, so I will upload them later.

Other than Musashi, there were a few other Japanese swordsmen that were undefeated throughout their lives, like Tsukahara Bokuden or Itto Ittosai. They also developed different swordsmanship styles. What I liked about Musashi most, other than his martial skills, was the attitude of self-reliance he had and that he didn't conform to the norms of society at that time (it was customary for known swordsmen to open schools under the patronage of a lord or serve as instructors to the shogun). Instead, Musashi just kept traveling from place to place without remaining the retinue of a daimyo (at least until he went to the Hosokawa).

By the day, that drawing of Musashi comes from the Vagabond manga, which is about Musashi's life, and I highly recommend it, it's an excellent series. A mix of historic facts and fiction, but you definitely should give it a try, even if not for Musashi, it has sword fights and it's really well drawn.

There is a fiction novel written about Musashi, by Yoshikawa Eiji, which I also recommend.

The Ilium/Olympos series by Dan Simmons.

Humans in a distant future have a way to witness the famous battle between Troy and the Greeks as if they were there. Some history scholars picked from various ages are able to actually teleport there and report the historic accuracy of the events to the Greek gods..which are not what they seem. Eventually, the Trojan war will digress considerably from what it was supposed to be. The humans who were watching it will also have to start a fight of their own for their survival, and there are sentient machines interested in Shakespeare and Proust that will also play an important part in the plot.

The Night's Dawn Trilogy by Peter F. Hamilton

The story is set in a future where humanity has colonized a lot of space, there are also sentient ships and some living space stations where humans can transfer their memories when they die. Something causes the souls of all who died in the past to return to the world and possess the living, while also having some special powers. A war erupts between the possessed who need living hosts to bring even more souls into the world and the humans who haven't been possessed yet.

I really enjoyed these series, both have many characters and alternate sub-plots at the beginning, before everything converges to the final climax.

Just wanted to share a site that I've just found:

http://www.cybrary.it/

Apparently they offer free classes on networking, pentesting, forensics, etc.


The classes themselves seem to be just videos and links to additional resources. I can't say anything yet about their quality since I just stumbled upon it, but you can take a look at the huge and disproportionate screenshot I took of their course catalog:

There is a free Bitdefender version with positive reviews, you can check it out at http://www.bitdefender.com/solutions/free.html

I never used it so can't say whether it's really good or not, but I will give it a try since I have to install an AV product for my family PC.

Through the years, I have used a combo of Kaspersky Antivirus + Comodo Firewall with IPS protection, and it worked for me, but it's true that Kaspersky is a resource eater, and you have to tweak things a bit if you want to use a combination effectively.

For web protection, Malwarebytes Pro offers that, although I've found it annoying and prone to false positives on some sites. I think a combination of addons like NoScript and common sense when browsing would be more useful than a security suite for web surfing.

There is also an anti-spyware program called Spybot Search and Destroy that performs what they call immunization on browsers to block malware infected sites, but the program is another resource hog, and I can't say how beneficial it really is. And as an aide, when I did a routine port scan against my system with Spybot installed, I discovered some of its services were listening for who knows what.

Just keep in mind that the antivirus solutions are far from perfect and could actually be used against your system. There was a very interesting paper I read about attacking AV programs that you can find here:

@Phage Thanks for the additional info. I looked into some statistics too, and all appears to be well, at least for the moment. Of course, I have a hard time trusting them after some of their earlier misinformation, but they couldn't make up numbers for something so serious either, especially since the international community is also keeping an eye on the Fukushima developments.

@Pak_Track Now I'm chill, you should have seen me the first day. Someone was complaining about I don't remember what, and I said "That's no big deal, I'm going just 300 km away from a nuclear apocalypse. I'll come back with extra arms."

I am still interested in bringing a Geiger counter with me though  ;D

Glad that humongous post didn't scare people away!

@Phage I picked up a few pieces of info about radiation and nuclear power plants during my search, but not enough to have a clear picture. If you have the time and the disposition to educate me further on the subject, I would appreciate it!

@Pak_Track In my opinion, Japan is playing with fire where nuclear power is concerned. Here's a map with the nuclear power plants in Japan:

http://en.wikipedia.org/wiki/Template:Japan_nuke_plant_map

The biggest problem is that it's a country prone to earthquakes, and there's no telling how many of the power plants have design faults, or are just old, to be safe. I read somewhere that the Fukushima power plant had some flaw in its design, that the company didn't deem important enough to correct. Also, the way they handled the incident and kept information from the public doesn't make them too trustworthy.

From a rational standpoint, I too would agree that the background danger couldn't be that high. Tokyo would have to be evacuated, and this incident is already more international than domestic. It's not some mountain village that can be kept in the dark about the underlying danger. Also, if the reactors pose a threat to North America, it wouldn't make sense for them to sit on their asses and just hope for the best.

There is also the fact that Fukushima may be in cold shutdown, but the damaged reactors need continuous cooling (and failure to do so may result in another, or even bigger disaster). Their latest idea is to build a wall of ice to contain it. They also need to remove the fuel rods, which is an in-progress operation. I think it's supposed to be completed by the end of the year, if all goes without incidents. But the underground radiation is supposedly reaching to high depths, and there is fear that it may eventually contaminate Tokyo's aquifer (again, this is not something much discussed in Japan).

My main concern will be the food, as I will have no way of really knowing where it came from. For things bought in supermarkets I can check the labels (although relabeling might obfuscate the true origin of the food). But for restaurants and the like, I can't really barge in with a Geiger counter and demanding papers that attest the safety of all they have in store

I am thinking to bring some potassium iodine pills with me just in case, and buying a Geiger counter, if I can find one for cheap. Always wanted to have one, but more for the thrill and curiosity, not actual experience.

All things being said, I will surely be suspicious about everything while the Fukushima problem remains unresolved:

*rain*
Does it carry radiation from Fukushima?

*wind*
Does it come from the direction of Fukushima?

*food*
Did this [random food] grow in irradiated soil / eat irradiated food / swim in irradiated water?

*insects*
A mosquito bite! Was it a radioactive mosquito?

*earthquake*
To the airport!

Fun fun

General discussion / Fukushima - what is the truth
« on: August 27, 2014, 08:43:52 pm »
I have always been fascinated by Chernobyl. I couldn't point out what exactly interested me, was it the effects of an enormous power gone out of control? The easiness with which humans could destroy themselves and the planet? The spark of genius that led to the invention of nuclear technologies? I couldn't say. I didn't try to better understand nuclear technology, I just felt content with watching Chernobyl documentaries, watch the desolate area and wonder about the danger hidden deep inside, and marvel at the surrounding nature that tries to reclaim its course. This interest waned for a while, until I regained it by, you will laugh, playing the STALKER games. There was something in them, the atmosphere, that rekindled my earlier fascination with Chernobyl. This also prompted me to watch the movie and read the novel. But I will get more to the point of this post now. Just wanted to add some background to this post.

When the earthquake in Japan happened in 2011, I followed the developments more keenly than I would have for another disaster because I had a personal connection with the country, having been there and knowing people there. Eventually, the things improved somewhat, and I was impressed by the Japanese ability to recover and move forward in such a short time. I was also relieved to see that none of my friends there were hurt. Then I stopped looking into it, feeling that things were under control. I also didn't exhibit the same interest for Fukushima as I did for Chernobyl. I was happy to see things didn't escalate in an even more serious disaster, and let it go.

To my shame, the reason I am writing this now and looked more into it after 3 years since the initial incident is not some sudden scientific interest, or detached curiosity. Being convinced that all is well, I didn't feel the need to investigate it further. But I've been granted a scholarship, and I am going to move to Tokyo shortly, for a period of 1.5 years. And someone brought up to me the discussion about Fukushima and the danger of radiation in the Eastern area of Japan. In my comfortable ignorance, I was surprised by this and quickly wanted to discard it by proving that the crisis is over and all is well. And what better way to do that than some quick research on the internet?

That was 2 days ago, and what I thought would be a 30 min break from my other activities, turned out to be 2 full days of reading, watching, and talking about what I discovered. And the more I did that, the more worried I became. And the more I marveled about how I stayed so blissfully ignorant about such a matter, even though I knew I would be going to Tokyo for some time.

However, this is the internet, and one can't take everything at face value. I always laughed at the doomsday preachers and the people who expected apocalypse because it was predicted by X, the planets are aligned in the Y formation, and all such nonsense (in my opinion). But when I tried to ascertain whether Fukushima is a danger to Tokyo, it actually became clear that it's a much higher danger to the entire world than I thought.

Below I will drop some links with a quick summary. But I am not knowledgeable in such matters. As such, I may not be able to discern accurate information from fabricated lies / overreaction / mere speculations. What worries me might be quickly disregarded by people with more know-how. Of course, I would be happy if that were the case.

http://www.naturalnews.com/041881_fukushima_radiation_leaks_deception.html

Most, if not all of these, are from 2014, so fairly recent and relevant, in my opinion.

And here are some more random things that I recall reading:

- Tepco was falsifying documents pertaining to nuclear plants, to avoid costs and inspections. To lower the costs, they apparently used duct tape to seal some leaking pipes inside the plant. They also knew about the reactors entering meltdown after the earthquake, but insisted all is well and didn't report it until some time after

- One of the ways the Japanese government has tried to persuade its citizens that there is no danger was by telling them to smile, because radiation doesn't affect happy people (this is too good so here's a link)
http://www.naturalnews.com/041720_fukushima_radiation_japanese_government_propaganda_brainwashing.html

- The destruction of the plant by an earthquake or the incapacity of the authorities to keep cooling the reactors might turn into a worldwide disaster that would affect the entire world. Also, the radiation released would render North America and Canada uninhabitable (again, this is something I have no sufficient knowledge to comment about)

- The Pacific ocean is poisoned by the contaminated water that is being tossed down into the ocean ( I read somewhere about figures like 200 to 400 gallons every day).

- There is no international organization helping Japan to solve this crisis, mainly because the Japanese are refusing assistance? I don't know if that is the case, but how could the other countries of the world stay silent in the wake of such an ongoing disaster, and with the potential to do even more destruction? This I find terrifying, if it really is the case.

- If you ask the Japan government, all is well. The radiation in Tokyo is lower than in other cities of the world. The rice grown in Fukushima after rice paddy decontamination is tested and perfectly safe to eat. The situation is under control.

There is much more to this subject, but the length of this post exceeds safety limits already ( I picked up some nuclear lingo, it seems).

I don't have a conclusion, or even a question to end this post with (there would be too many of them). I am just wondering about what might be true, and what are just exaggerations born of fear. Of course, I am also thinking about my safety. The media coverage is very modest when it comes to what might be a bigger nuclear disaster than Chernobyl. In Japan, that may be understandable, because they apparently have a law that spells prison for sharing what they deem state sensitive information. It's called the state secrets law or something like that. But I can't believe the rest of the world is ignoring this. Unless the danger really isn't that serious. Wouldn't that be good, but I am skeptical.
