Its the height of summer, a hot time, a family time, and not much hobby stuff going on to feed the blog but there are nearly 2,000 posts published over the last 10 years so time to bring a few back for a look.

I'll start with the Raid on St. Michel from 2010 when the blog was new. Rob and I had decided that for the HAWKS room at Cold Wars 2010, we would play through the scenarios from Charles Grant's recently released "Raid on St. Michel" using the HAWKS' collection of homecast 18thC troops, set during the Not Quite The Seven Years War (NQSYW). Rob and I acted as Impartial (or balanced bias) game masters with convention gamers signing up to play the battles helped out by some of the HAWKS where there was space.
The posts can be pulled up by clicking on the Raid on St. Michel label but they come up starting with the end so here are separate links in the proper order.

In the first post of this year, I want to share some content from the book I'm reading at the moment: Playing smart - on games, intelligence, and artificial intelligence by Julius Togelius. The author discusses many aspects on how games challenge us and what we can expect from games that use artificial intelligence in the near future.

One of the first points discussed by Togelius is about the question I already brought many times in this site: why do we play games? It's not easy to answer (and we have many different views for this subject) but I think it's essential to gather multiple points of view to create a more solid opinion.

Togelius launches the question: why do you play games? And starts his answer with a very interesting argument that most of the time we are playing games for many reasons but all the time – despite the game we are playing – we are doing an exercise of intense planning.

Below, I want to share this excellent content from his book and recommend the reading for all the followers of this site:

Why do you play games? To relax, have a good time, lose yourself a bit? Perhaps as a way of socializing with friends? Almost certainly not as some sort of brain exercise. But let's look at what you are really doing: You plan. In Chess, you are planning for your victory by imagining a sequence of several moves that you will take to reach checkmate, or at least capture one of your opponent's pieces. If you are any good, you are also taking your opponent's countermoves into account and making contingency plans if they do not fall into your elaborately laid traps. In Super Mario Bros., you are planning wheter to take the higher path, which brings more reward but is riskier, or the safer lower path. You are also planning to venture down that pipe that might bring you to a hidden treasure chamber, or to continue past it, depending on how much time you have left and how eager you are to finish the level. You may be planning to eat the power-up that lets you get through that wall so you can lick a switch that releases a bean from which you can grow a beanstalk that lets you climb up to that cloud you want to get to. In Angry Birds you are planning where to throw each bird so as to achieve maximum destruction with the fewest birds. If you crush the ice wall with the blue bird, you can then hit that cavity with the black bomb bird, collapsing the main structure, and finish off that cowardly hiding pig with your red bird. (TOGELIUS, 2019, kindle edition – position 412)

It was released in October 2001 for the PlayStation 2, in May 2002 for Microsoft Windows, and in October 2003 for the Xbox. A remastered version of the game was released on mobile platforms in 2011, for the game's tenth anniversary. It is the fifth title in the Grand Theft Auto series, and the first main entry since 1999's Grand Theft Auto 2. Set within the fictional Liberty City, based on New York City, the game follows Claude after he is left for dead and quickly becomes entangled in a world of gangs, crime and corruption.The game is played from a third-person perspective and its world is navigated on foot or by vehicle. The open world design lets players freely roam Liberty City, consisting of three main islands. Development was shared between DMA Design, based in Edinburgh and Rockstar, in New York City. Much of the development work constituted transforming popular series elements into a fully 3D world. The game was delayed following the September 11 attacks, to allow the team to change references and gameplay deemed inappropriate.Upon release, the game received critical acclaim, with praise particularly directed at its concept and gameplay. However, the game also generated controversy, with criticism directed at the depiction of violence and sexual content. Grand Theft Auto III became the best-selling video game of 2001, and has sold over 14.5 million copies since. Considered one of the most significant titles of the sixth generation of video games, and by many critics as one of the greatest video games of all time, it won year-end accolades, including Game of the Year awards from several gaming publications. Since its release, it has received numerous ports to many gaming platforms. Its successor, Grand Theft Auto: Vice City, was released in October 2002.

From time to time, I get disappointed how much effort and money is put into securing computers, networks, mobile phones, ... and yet in 2016 here we are, where not much has changed on the defensive side. There are many things I personally blame for this situation, and one of them is the security tips.

The goal of these security tips is that if the average user follows these easy to remember rules, their computer will be safe. Unfortunately, by the time people integrate these rules into their daily life, these rules either become outdated, or these rules were so oversimplified that it was never true in the first place. Some of these security tips might sound ridiculous to people in InfoSec nowadays, but this is exactly what people still remember because we told them so for years.

PDF is safe to open

This is an oldie. I think this started at the time of macro viruses. Still, people think opening a PDF from an untrusted source is safer than opening a Word file. For details why this is not true, check: https://www.cvedetails.com/vulnerability-list/vendor_id-53/product_id-497/Adobe-Acrobat-Reader.html

On an unrelated note, people still believe PDF is integrity protected because the content cannot be changed (compared to a Word document).

Java is secure

One of the best ones. Oracle started marketing Java as a safe language, where buffer overflows, format strings and pointer-based vulnerabilities are gone. Unfortunately, they forgot to tell the world that instead of "unsafe programs developed by others" they installed their unsafe program on 3 billion devices.

Stay away from rogue websites and you will be safe

This is a very common belief I hear from average people. "I only visit some trusted news sites and social media, I never visit those shady sites." I have some bad news. At the time of malvertising and infected websites, you don't have to visit those shady sites anymore to get infected.

Don't use open WiFi

I have a very long explanation of why this makes no sense, see here. Actually, the whole recommendation makes no sense as people will connect to public WiFis, no matter what we (InfoSec) recommend.

The password policy nightmare

Actually, this topic has been covered by myself in two blog posts, see here and here. Long story short: use a password manager and 2-factor authentication wherever possible. Let the password manager choose the password for you. And last but not least, corporate password policy sux.

Sites with a padlock are safe

We tell people for years that the communication with HTTPS sites are safe, and you can be sure it is HTTPS by finding a randomly changing padlock icon somewhere next to the URL. What people hear is that sites with padlocks are safe. Whatever that means. The same goes for WiFi - a network with a padlock is safe.

Use Linux, it is free from malware

For years people told to Windows users that only if they would use Linux they won't have so much malware. Thanks to Android, now everyone in the world can enjoy malware on his/her Linux machine.

OSX is free from malware

It is true that there is significantly less malware on OSX than on Windows, but this is an "economical" question rather than a "security" one. The more people use OSX, the better target it will become. Some people even believe they are safe from phishing because they are using a Mac!

Updated AV + firewall makes me 100% safe

There is no such thing as 100% safe, and unfortunately, nowadays most malware is written for PROFIT, which means it can bypass these basic protections for days (or weeks, months, years). The more proactive protection is built into the product, the better!

How to backup data

Although this is one of the most important security tips which is not followed by people, my problem here is not the backup data advise, but how we as a community failed to provide easy to use ways to do that. Now that crypto-ransomware is a real threat to every Windows (and some OSX) users, even those people who have backups on their NAS can find their backups lost. The only hope is that at least OSX has Time Machine which is not targeted yet, and the only backup solution which really works.

The worst part is that we even created NAS devices which can be infected via worms ...

Disconnect your computer from the Internet when not used

There is no need to comment on this. Whoever recommends things like that, clearly has a problem.

Use (free) VPN to protect your anonimity

First of all. There is no such thing as free service. If it is free, you are the service. On another hand, a non-free VPN can introduce new vulnerablities, and they won't protect your anonymity. It replaces one ISP with another (your VPN provider). Even TOR cannot guarantee anonymity by itself, and VPNs are much worse.

The corporate "security tips" myth

"Luckily" these toxic security tips have infected the enterprise environment as well, not just the home users.

Use robots.txt to hide secret information on public websites

It is 2016 and somehow web developers still believe in this nonsense. And this is why this is usually the first to check on a website for penetration testers or attackers.

My password policy is safer than ever

As previously discussed, passwords are bad. Very bad. And they will stick with us for decades ...

Use WAF, IDS, IPS, Nextgen APT detection hibber-gibber and you will be safe

Companies should invest more in people and less into magic blinking devices.

Instead of shipping computers with bloatware, ship computers with exploit protection software

Teach people how to use a password safe

Teach people how to use 2FA

Teach people how to use common-sense

Conclusion

Computer security is complex, hard and the risks change every year. Is this our fault? Probably. But these kinds of security tips won't help us save the world.

What is Bug Bounty ?

A bug bounty program, also called a vulnerability rewards program (VRP), is a crowdsourcing initiative that rewards individuals for discovering and reporting software bugs. Bug bounty programs are often initiated to supplement internal code audits and penetration tests as part of an organization's vulnerability management strategy.

Many software vendors and websites run bug bounty programs, paying out cash rewards to software security researchers and white hat hackers who report software vulnerabilities that have the potential to be exploited. Bug reports must document enough information for for the organization offering the bounty to be able to reproduce the vulnerability. Typically, payment amounts are commensurate with the size of the organization, the difficulty in hacking the system and how much impact on users a bug might have.

Mozilla paid out a $3,000 flat rate bounty for bugs that fit its criteria, while Facebook has given out as much as $20,000 for a single bug report. Google paid Chrome operating system bug reporters a combined $700,000 in 2012 and Microsoft paid UK researcher James Forshaw $100,000 for an attack vulnerability in Windows 8.1. In 2016, Apple announced rewards that max out at $200,000 for a flaw in the iOS secure boot firmware components and up to $50,000 for execution of arbitrary code with kernel privileges or unauthorized iCloud access.

While the use of ethical hackers to find bugs can be very effective, such programs can also be controversial. To limit potential risk, some organizations are offering closed bug bounty programs that require an invitation. Apple, for example, has limited bug bounty participation to few dozen researchers.
