Week 5 [13-19.11.17] How to protect ourselves against cyber threats and cyber criminals


There is a broad variety of cybercrimes like fraud, cyberterrorism, computer as a target etc. A study by Juniper Research estimated that the cost of cybercrime could be as high as 2.5 trillion by 2020. To put it into perspective, there are only 8 countries with their GDP bigger than that. The world’s top illicit business, listing drugs, counterfeit, human trafficking,  estimates  at 0.5 trillion.




You might be interested why governments don’t fight with it.  There are a few main reasons. First of all, laws around the world regulate the internet differently even though all agreed that the internet is international.  What makes "solving" cybercrimes particularly difficult is that attribution is hard. ?? Because it is so hard to pin down those involved in cybercrime, experts  believe the best way to fight it is to disrupt their activities as much as possible.

The only way to protect against cybercrime is not to use the computer. You just have to accept that for the convenient use of technology you sacrifice security. So there is always a tradeoff between security and convenience, but there are good practices in day to day use of gadgets you can follow to achieve high level of security:

Use latest version of software available and don’t turn off auto-updates. Older software usually contains vulnerabilities and you want to benefit from the latest security patches.
You don’t want to use your Facebook password to login you online banking. Create different passwords for different accounts. That way even if someone steals or breaks into your accounts they won’t have a chance to get the rest.  An easy way to achieve that is to use “Password Manager”. There are quite a few of them on the market.
Obviously you don’t want to use pirate content due to the possibility of viruses inside.
Don’t open links to unknown sites. Usually they try to steal private information or download malicious programs onto your computer.
A good way to protect sensible information like photos, documents, private info not only from hackers but also from hardware failure is to make regular backups.
The last but not least do not use public Wi-Fi to things you don’t want to share with everybody around you. There is absolutely no guarantee that the connection you use is secure.
By following these rules you will become less vulnerable than 98% of internet users.
Be safe.

Questions:
What is the last cybercrime you heard about?
What kind of measures do you take to prevent your data from being hacked?
Have you ever been hacked and\or had a virus?
Do you like Mr. Robot series?

Comments

I'm trying to read sites like Sekurak or Niebezpiecznik, so I'm seeing a lot of that stuff. Most famous recently was probably a WPA2 thing. It was commented not only at IT community, but also at the neutral information stations and websites.

I'm using Ubuntu for most time and it's well known fact that there are less viruses crated for Linux than for Windows, mostly because it's less popular. Also when you are downloading something at Linux, first you must give rights to file, so it can be run. Buying legal software and games is also great way of increasing safety of our PC's. Other thing that I'm doing to prevent myself from cyber threats are opening only trusted emails and using well known and trusted sites (for example I'm using Netflix instead of zalukaj etc.). If you have laptop, it's important to remember that you can not connect to every random WiFi you find. While using Windows, it may be good plan to use some popular and not free ant ivirus program like BitDefender,

I've never been hacked (or I'm just thinking that I've never been), but I used to have some viruses on my old PC, but buying good anti virus program was enough to remove it.

I really like Mr. Robot. Despite having great story line and good acting, especially by Rami Malek, Mr. Robot is great show because it shows hacking as it is. There are no hackers that looks like Giorgio Armani model, hacking does not look like playing adventure game and it's strong stuff for geeks.

The last cybercrime I heard about was few days ago when I noticed info about website of the Modlin Airport. It was hacked and there was no way to get to it, there was only a logo of hackers team and creepy sound.
Generally I often like to make everything to be secure in the internet. The first thing I do is trying to stay anonymous. The other thing and I think also very important I like to be aware of sites I visit and If I’m not I just try to avoid such websites. I always update software I use.
As everyone using internet I also had some viruses on my computers but I was able to avoid hacker attacks. I like Mr.Robot series as I commented few articles ago.
To keep my data safe I use a password manager and multi-factor authentication if online account offers one. I also have antivirus system installed and make regular software updates. I do believe the most important thing is to be a selective sharer. If we are not careful tons of personal information can be obtained by unwanted people. We should simply be smart when it comes to internet - don’t click on any link from an unknown source, only access trusted websites that start with https, instead of just http, and have a padlock icon in the URL field.
Wannacry ransomware attack is the crime that i heard about in may 2017. I was a fan of doing things like hacking 2-3 years ago,but not interested in it anymore.
Updating already existing default software and saving all my important files on SSD are the main things i do to prevent stealing my files.
Yeah,i think everobody was hacked at least one time in his/her life. It was when i started using computer, about 15 years ago, unknown applications were installed on my computer and i could not even drag my mouse.
I watched about 5 episodes and i was not suprised. Honestly,i don't watch movies or TV series at all.
Yevhen Shymko said…
You seems quite advance, have you ever tried to hacking?
Yevhen Shymko said…
"saving all my important files on SSD" Are you sure you actually saving it? You made it sound like you prevent disk failure not hacking.
The last cybercrime I heard about was, besides what you can read on niebezpiecznik.pl, is that my friend was phished (someone took over his friends facebook), and persuaded to give money because of something.
It is hard to find a good method to prevent everything, two months there was found a backdoor in bluetooth, couple of weeks ago in WIFI. Also often we can hear about database leaks (with user passwords) of some services, so the question is how does this services prevent from beeing hacked? Besides that I am very sensitive to phishing and social engineering methods.
Sure I was hacked. Once, about 10 or more years ago, some application caused that I get so many notifications about some mails, on my screen, that I could not do anything on the computer.
I watched the first season, and almost droped after couple of episodes of the second... Maybe I will return to it some day. First season was great, second get me bored a little bit.

Maybe 2 or 3 month ago i read about CCleaner ( don't remember what was site).
and I was shocked ... CCleaner which should to clear and protect your PC has virus Trojan which get all information about your PC and send to the server CCleaner.
CCleaner - which have licensed where was wrote that the all information will be a secret...

infosec is a very interesting topic.

Not the most recent cyber security breach but the one that comes to my mind right now is Dell losing control of its customer support side that was supposed to assist its customers in recovery from malicious software (!). The site was hijacked for a month this summer by a group that specializes in malware attacks.

To stay safe I don't reuse passwords (be careful with Password Managers, they happen to be hacked as they are a valuable target for hackers), don't connect to any network I don't trust, install all security updates, and try to be mindful of all applications I install on my machines and phone. I keep tight security on my browser. I'm on linux so I make sure I only use legitimate repositories (which is hard to check and not a safe bet in general). Linux only decreases a chance of getting hacked, there is still Windows malware that can run on Linux due to the cross-platform frameworks. I try to follow https://krebsonsecurity.com/ and some lightweight security tweeps for fun like @SwiftOnSecurity.

Last time i heard about cybercrime was couple years ago. I was talking about the situation when Playstation Network was hacked. I do not remember the group which was responsible for that but all the media was talking about it.

Normally I do not use any of the antiviruses softwares, but I consider myself as very cautions person. I do not visit the websites which look suspicious, all my passwords are quite strong and I try not to use the same password on different sites.

When I was kid, I didn't realize the danger which was waiting behind the corner and due to that, I lost my character in Tibia. :(
Patryk Pohnke said…
The WannaCry ransomware attack, which was huge case all aroung the world. Even some polish companies were hurt.
I'm using different passwords for different sites.
I'm not using any antiviruses so probably I have some. I doubt that I downloaded anything harmful, because I am very careful about websites I visit.

I reading 'Blackout' book now and the main plot is about cybercrime. This book became quite popular so I think many of people know what is about.
As far as I know I have never been hacked but on the other hand I could be and I'm not aware of that.
Once I watched one episode of Mr. Robot and I didn't like it.
The last cybercrime that came to my mind was this situation that happened to our school administration site. When it was hacked by some Turkish hackers.

Most of my really important stuff I am keeping on pendrive so its not connected to network.

Sure I had a virus. When I was young and wanted to watch a movie on illegal site I clicked stupid ad that contained one.

Bow to Remi Malek xd
The last biggest cybercrime i heard was about CCleaner. I didn't remember precisely what actually happened but i know that a software that should be cleaning our PC contains some kind of virus which was stealing our data!
I'm trying to read websites about latest cyber-frauds, watch out for strange links, keeping my software up to date and listening to my antivirus. There are a lot of other measures i do but i listed some of them.
Yes, about one year ago some russian steal my Steam account and to be honest, i still have no idea how he did it! Maybe some phishing way.
I watched Mr. Robot's first season and I like it, but with no love.
Unknown said…
I try to follow some InfoSec guys on Twitter so the last thing I heard was BadRabbit ransomware 2-3 weeks ago.

Most important thing, I don't use an admin account on Windows. I work on normal user account. Also I use password manager so now I have long passwords to Facebook, Twitter etc.

Fortunately I have never had any virus on my PC. Or I just don't know about any... ;)

I really like Mr.Robot series, because so far it has the most realistic hacking content in TV/cinema history. And I also like the plot and the actors.
Jakub Lisicki said…
The last cybercrime I've heard about is database theft of some polish jewelry store and attemt to blackmailing the clients into sending ransom.

There is really a lot of countermeasures I take in order to be protected from any hacking attempts. The most basic one is simply setting up strict rules on my local Iptables configurations, using really complex passwords and password vault in order to keep track of them safely since all of them are different and pretty often changed. First of all though, I don't share the ways of keeping myself safe on-line.

I've obviously downloaded virus-infected files numerous times, but it doesn't mean I had my device infected (at least in the last couple of years.)

Mr.Robot is really well written series focused on IT Security, governments and human mind. I personally think that the first season was much better than the second one, but I am willing to give it another chance once the season 3 gets released.

I remember when viruses were like just to troll you, or make you format your computer. Now it is focused only on wringing the money from users by unlocking(or not) their encrypted personal data done by some viruses. No more bouncing happy faces on your desktop or playing 8bit music. In order to fight that i use 2-3 different paid anti-viruses. Keep my software up to date and I try to avoid shady urls/files but it is not always possible when you are browsing dirty internet :)
WannaCry Ransomware was the last global scale cyber threat i hear about. Having its toll on many public facilities and many computers it had a huge impact on some peoples day to day lifes.
As for my counter measures: First of all i encrypt data i deem to be important, that way even if one were to get it it would be hard to actually read it. Secondly i try to be aware of what links i follow, i find myself even double checking google sites if they look different that what i remember them as from before. I also dont install untrusted software, if i have to im using Virus Total before executing .exe files, compressing zip files and even sometimes downloading files from sites. Lastly i take care whenever im prompted to login i doublecheck certificates, and the address of the site im logging on, as silly as it sounds if everybody would do so we would have virtually no phishing attempts out there.
Couple of times i caught a virus onto my PC, mostly because i felt safe with Anti Virus software i was using at the time but since i abandoned AV software(i dont use any ) it became my habit to protect myself and never feel safe. Haven't had a virus ever since.
Dont watch the MR.Robot at all not much time these days.

I often read articles on websites like 'Niebiezpiecznik'. There are a lot of informations about viruses. It is very strange that software is vulnerable to attacks.
I've never been hacked because I'm using different passwords for different websites. We should be safe on the internet. There are a lot of fake advertisements which contains viruses.
I've never seen Mr Robot but I want to watch it. I love movies about technology.
Filip Sawicki said…
The last cybercrime happened in the company I am working for. There was a ransomware that spread across the network and infected all windows computers. Fortunately, almost all developers use Linux as a base operating system, so no confidential information was lost.
Personally, I have some basic steps to be 99% certain that I won’t be hacked. Obviously if someone really wants to hack you, he will given some time. Nevertheless, first of all we should use different email addresses for different usages, for example one for private mails, second for online purchases and third as a kind of dump. Secondly use different randomly generated passwords for each email account, this will make it almost impossible for hackers to crack. Thirdly always check websites to ensure safety of your private data, this means knowing how your passwords are stored in the databases. There are also other steps like changing password every 3 months or when the website with your account registered has been hacked, using both malware and virus protection on your PC, communicating using private-public key encryption and never ever using public Wi-Fi.
Phishing scams, in my opinion, the most dangerous one.These scammers would contact with you out of the blue, via email, text message, phone call or even through social media, pretending to be a legitimate business such as your bank, telephone company or even internet provider.In fact, they are going to steal from you. Of course, it's some other types of cybercrime like - malicious software, email bombing, virus dissemination, electronic money laundering and a lot of other.
I saw 1 series of Mr.robot and I would say I'm, not a big fan
Oh I’m not really sure what was the last cybercrime I heard about. Probably one of many ransomware attacks like WannaCry.
To prevent being hacked I use different passwords on every site that I log into, and when it’s possible I always use 2-factor verification.
I have never been hacked nor had a virus, because I use antivirus software and I’m aware on what sites I browse into.
Unknown said…
The thing is - a smart virus wouldn't let you discover it. I do not think I have had one for the past few years since I take a lot of precautions to protect myself such as not downloading files from unknown sources but I can never be sure. My father is not very cautious and because of that I had some problems with my ip adress being a source of denial of service attacks and some spam filters blocked me from accessing few websites such as niebezpiecznik.pl. Fortunately I have solved this issue and haven't had any problems ever since but it is probably just a matter of time until it happens again. Too bad my parents don't want to abide the rules I gave them to protect themselves.
Yevhen Shymko said…
They can gather anonim info but yeah... It didn't help to build trust to such companies... Just look at how many info windows gathers...
Yevhen Shymko said…
How do you remember all the passwords for different sites?
Yevhen Shymko said…
Have you tried to protect yourself against viruses?
Yevhen Shymko said…
Then you just HAVE to watch Mr Robot. It's exactly about tech + it will show you that the weakest link in the chain is actually human... And software write by humans... I think you get where I'm leading)
Yevhen Shymko said…
Don't you feel irritated when you have to do 2-factor authentication in day to day life?
Unknown said…
1. Lately I’ve heard about Scottish Parliament being subjected to brute force cyber attack.
2. I’m using macOS, which is safier. There are more viruses created for Windows, so I’m only playing games on it. I’m also very careful about websites that I’m visiting. There are a lot of clickbaits, etc. that we have to avoid.
3. Nope, I’ve never been hacked, but like most of people I’ve had some viruses, but it was years ago, when I didn’t know how to use internet properly.
4. Yes. I enjoyed it, but the first season only. We were talking about it in some other article ;).
Tomasz Morawski said…
The last cybercrimes I can remember were WannaCry and NotPetya. I even felt the effects of the latter, since the company I work for had to stop operating for a while due to attack on one of our partners. Luckily, they dealt with it quite fast so it didn't cause much harm.
To be honest the only precautions I take is coming up with some tricky password. It's probably because I don't store any valuable assets on my PC or in the internet.
The only time I have been ever hacked was in my primary school when I used to play Tibia. I downloaded a Tibia bot infected with some trojan horse and had my account hacked. I remember I lost some good items but I managed to change the password on another device before the hacker took everything my character had.
Well, even though a lot of people recommended it, I've never watched Mr. Robot. I'm into Polish series currently so it'll probably take some time before I start it but it's definetely somewhere on my list.
Wojtek Protasik said…
I have read a book about Kevin Mitnick, quite a well-known figure in a cyber security world. He started as a nerd and finished as a world class hacker. I believe that the best hackers are those who were not discovered yet but still this guy has a lot on his account so I recommend you his book. I haven't experienced being hacked yet and I hope it won't change. I use internet carefully and I mind what website I enter and what data I leave. I had a virus once, it was obviously caused by surfing the web and playing some online games. I learned my lesson, it wasn't anything serious.
Unknown said…
I find this article very useful. Some time ago I got a lessons about phishing, because I clicked for link from unknown source. Nothing happened, but it was possible.
This is very irritating for me to make long and complicated password, to change them often, that when I wan to login in from different device I have to submit it by typing some codes.
I hate the fact that this is important and necassary because there are people who are lookinh for someone who don't like changing password and everywhere same one.
Unknown said…
I read forums about cybercrime quite often, there are a lot of cybercrimes everyday but the biggest one was Bad Rabbit(new version of notPetya). Actually I am not using any antivirus. I change my password every 1-2 months. I am trying to make different passwords for every site. When I was young Ive been hacked in MMORPG game. I had 11-12 years old and downloaded virus from not trusted site. After that I started to be more careful. I love Mr. Robot series! I can not wait for more episodes.

All of these examples to protect your computer are basic for me. I don't remember last cybercrimes but we hear all the time about this. Anonymous group is very popular today. Personally I don't use any antyvirus programs because I think that these kind of programs slow down my computer. Once again I read about Mr.Robot series on this blog and I think that I must watch this today.
Unknown said…
The last cybercrime and most common that I heard about is using Adblock. Sites want to earn money and people are eager to block site's source of money. To prevent my data from being hacked I use different passwords at every sites, and I use keepass to manage those different passwords. I have many times had a virus when I was using anti-virus software. Since I stopped using that software and I am only using operating system build in security I don't know that I might have a virus.
Magdalena Popek said…
To keep safe I try to keep apps and system on my computer and phone up to date. I also don't use the same password everywhere and try to change them every once in a while. Also my antivirus works fine. I try to check the sites I download applications from, log out of websites. Fortunately this still works for me and I've never been hacked. I know it's hard, or even impossible I guess, to 100% prevent being hacked but there are some things we can do not to make it too easy.
Unknown said…
Well, the last one I remember and that doesn't come from security sites was when one of our (now ex-) employee opened an attachment and had their HDD encrypted... Well that was the time, running AVs on every other PC in the network to check if anything else was affected.
In corporate security, there is one phrase that's always on-time and always true:
>You can have the best money can buy AVs, top of the line firewalls and security policy so strict it doesn't allow people to move their monitors near window, but if you have dumb employees, nothing of the above matters.

Its true because you can always find someone who opens a mail with INVOICE.EXE, that will instruct them to delete all files and burn their PC in the name of Satan.
Personally I never had a virus, even though I've been to some shady sites with ads popping up everywhere, but a good adblocker, sometimes even scriptblocker and an AV blocked everything unwanted. The base rule here is - don't download files from shady hosting sites and "one-time-uploaders". Even though torrents aren't something I'm new to, I've never had a virus from downloading a torrent stuff.
Unknown said…
The last cybercrime I heard about is Sony (Playstation) servers being hacked AGAIN (who knows how many times it's been). It's the reason I never connect any card to my PSN account :)

When it comes to measures I take to be safe:
1. Buying all the software and games.
2. Not using apps from non-trusted sources on my PC.
3. Using SECURE passwords, not reusing them between accounts.
4. Using different e-mail addresses for different purposes (as I stated in one of the previous posts).
5. Changing passwords in reasonable time intervals.
6. Last but not least: watching out when I get e-mail that I shouldn't have gotten.

I've never been hacked, and only got viruses many years ago when I was a kid and did not even know what an anti-virus was. Basically, it takes some common sense to not suffer to these problems.

When it comes to the series - I watched it all but the new season and I loved it. I'm doing my best to find some time for the new teason though as I still did not manage to watch episode 1...

What is the last cybercrime you heard about?
The last cyber crime I heard was that known from Snowden movie. Which was about US Government which collects many data from every internet users in the world. I consider this as a crime because they violated people privacy and that situation could not be happening.
What kind of measures do you take to prevent your data from being hacked?
I watched out what I click and what tool I use. I recommend open source applications and encrypt as many as possible.
Have you ever been hacked and\or had a virus?
When I used windows that happened all the time, but in last time I don’t have that kind of issues.
Do you like Mr. Robot series?
Yes, I do :)

I can't remember last cybercime which I had heard in the last time. I have a updated software and I try to not use a websites which can be potentaily dangerous for my computer. I really protect my personal data and I use a gmail so I don't get a lot of scam on my e-mail address which could be dangerous. I also have a strong passwords for my accounts which I have never give anyone.

I had a account on very popular game - League of Legends which was hacked but to this moment I am not sure how it was even possible. I remind that some years ago I gave my login and password for my friend which was playing on my account for me. I am concious that it was only a my mistake and it is lesson for everyone - don't give your account information for anybody.

I have heard abotut Mr. Robot series but I didn't watch it yet.

The last news about cybercrime I have heard was about false Facebook's notifications. It was described in the article on the site Niebezpiecznik.pl.
The attack was relatively simple. Hackers were sending to any user a notification that his/her account is locked/suspended.
And to unlock the account users had just to click on the link. This link lead to a login panel of page that looked similar to Facebook. People re-entered their datas, believing that they had done it in the right way, but they were actually delivered to the hackers. On this way people were losing their Facebook accounts.
I haven't never hacked any computer, I also haven't been hacked thanks to websites warning me of Internet dangers.
I have watched the Mr.Robot serie and didn't fall into this.
Never hacked or never knew about it directly. Just trying to keep everything secure on the time and not to get fooled. But cyber criminals are currently getting number one threat list. And that will keep rising. We are using many mobile / internet technology to make our life easier. Even my fridge has an access to the Internet to check a list of things to buy is it 100% secure - of course not.

Mr Robot was great but only 4-5 episodes which was very technical. After that... they made from a really lazy and slow episodes with small amount of IT action. I liked his psychoanalysis of every person he has hacked :)
Marta Kowalczyk said…
'Mr robot' is quite a good series. It is basically a rip-off 'Fight club' movie made into series for computer geeks. But it is sill fun to watch. I really liked acting of Remi Malek. I love films that show emotional and psychological problems, and we have a lot of characters that struggle a lot not only with problems from the outside world, but also they fight with themselves.

Of course, I think everyone at this blog dealt with viruses in his or her life. But we have antiviruses, so it's not a problem.
Some people are really terrified of viruses or hackers. But I just don't understand it. Few people are hacked in everyday life. I mean, we are not superstars, we don't have accounts with millions of followers or anything like that. It's no use in hacking us. Yes, there is a possibility of hacking for money, but I don't think that this possibility is very big.
As to cybersecurity, there are few people who don't know about protection. Even my mom uses antiviruses and knows that she shouldn't use one password for many web-pages. And she is not connected with IT by any means.
Unknown said…
As we have seen on Mr.Robot before you can be hacked anyway if people want to. The best way not to be hacked on my opinion is to live on an island far far away from the technologies. No phone, no internet.
Patryk Pohnke said…
I have good memory :)
In fact I have different levels of security of passwords.
For irrelevant sites which don't contain any of my personal data I use common password dedicated for such websites.
Unknown said…
Well, petya attack is the last cybercrime attack I've heard about I guess.
To keep myself safe I don't click just any link that I see, lately I sometimes compare hashes of the software I download if I'm not sure the site is secured enough (that's what petya and ccleaner attack taught me), keeping the system up to date is also important. Never been hacked but had plenty of viruses in the old days, oh good old fun times. I love Mr.Robot, season 3 finally got some action. Highly recommend it.

The biggest hack I've heard recently was about sony being hacked. Multiple unreleased movies were obtained by group of hackers for North Korea. They demanded not to release movie "Interview" witch is essentially parody of Kin Jong Un.
Personally in order to secure myself form being easy target I change my password frequently and use a any-virus.
I became aware of existence of malicious program in early days of using computer when adware was common. Since then I use the best programs in order to protect myself.
The series Mr.Robot is one of best today. The research and being true to real life is just astonishing. All program, tools and vulnerabilities are being used by real hacker in order to steal our data.

Week 11 [03-09.06.2019] The problem with ecological cars emission in UK

The problem with ecological cars emission in UK Since the adoption of the European Emission Allowance Directive in the European Parliament, all car makers have tried to submit. Since 1992, the Euro I standard has been in force, which limited the emission of carbon monoxide to the atmosphere. The Euro VI standard currently applies, which limits the series of exhaust gases. These include: hydrocarbons, nitrogen and carbon oxides, and dust.   The most significant change was brought by the Euro IV standard. For the first time it introduced the limitation of nitrogen oxides, which are responsible for the harmful compounds of smog.   What is smog?   Smog consists of sulfur oxides, nitrogen and carbon. In addition, solid substances such as suspended dust (PM). Dust suspend in atmospheric aerosols may be in liquid and solid form. These can be particles of sea salt, clouds from the Sahara and artificial compounds made by people. These compounds often come fr

Week 4 [06-12.11.2017] This is what happens when you reply to spam email.

James Veitch is a British comedian. In today’s Ted Talk James with characteristic for himself a sense of humor shows how he deals with spam emails and why responding to junk messages may be sometimes dangerous. Questions: What do you think about James’s  way of dealing with spam? Why are junk messages legal, even though it sometimes may be a fraud? Dou you have a problem with spam? How do you deal with with it?
