HOW TO ACCESS THOSE SITES(BLOCKED BY UR OFFICE)?

1.    It is so common to see and hear that offices and corp-orates block ur most desired websites....so the smart ones try using proxy.....but what to do when even those proxies are so configured that u cannot access.....here goes step by step

- Suppose ur office has blocked yahoo.com.

- Goto Command prompt and type ping yahoo.com

- You get the yahoo ip ie 209.191.122.70(it may be different for you)

- Now convert these 4 octets into binaries with the help of a calculator in programmers mode.

- So u get 

209 @ 11010001

191@  10111111

122@  1111010

70 @   1000110

- Now place zeros in front of octet converted binaries who are not complete 8 in number count 

- So it becomes 11010001101111110111101001000110

- Now convert this to decimal again  and u get 3518986822

- Go to the browser and write http://3518986822

Thats it..kaam khatam....all the best....

UNDO A SENT EMAIL :YES,IT IS POSSIBLE!!

1.   Ever thought like u shouldn't have sent that mail....or u sent it too early....like all things u can do UNDO in your PC and various applications...can u do it in EMAIL?......the answer is YES.....

2.   The feature is currently available in Gmail and Blumail only.How?...it goes like this

- Log into your GMail account

- Go To mail settings tab.

- Click on Labs

- Scroll down u will find UNDO SEND

- Enable it.

3.  That's it.Actually the feature sends the mail about 5 seconds late so just in case u immediately realize that u send it too early or should have sent it later.....u still have control over it.So when u click send a small link appears that says "UNDO"...click on it and that action will not conclude...ur email remains safe with you.... 

POWERFUL THAN ADMINISTRATOR ACCOUNT : SYSTEM LOGIN

1.  So here is something unheard to those who thought that ADMINISTRATOR was the king of the respective PC account.So for those who think so...ever thought why r u unable to fiddle with system files when u r the owner... that's because there is a SYSTEM account over and above the administrator who can delete the administrator account!!!!yes u read it right....so how do u get to the system account.I am giving it a step by step attempt here with screen shots!!

2.  Firstly...get to your desktop and see ur user name...mine is windowsxp ie a user account with admin priveleges as shown below :

3.    Secondly,get to the command prompt and create a schedule to run cmd.exe as follows :

at 14:51 /interactive “cmd.exe”

*** The time mentioned here can be a minute or two ahead of whats the time u doing this action.

 4.   You can check schedule by typing “at“ and hitting enter after the above step.

5.    Now Wait for the time you set for the schedule and u see that cmd.exe would be launched at the specified time and a subsequent command prompt windows will open automatically.

6.    Now go to ur desktop without closing any window and reach the task manager and kill the explorer.exe file under the process tab.

7.    Close the first cmd window and not the second one.

8.    Reach the root directory by pressing cd\

9.    Type start explorer...thats it...now u logged in as the System.....as shown:

 10.   Point to note :

- This is only for educational and info pupose.
- Never attempt it on a live system.
- Always do it on a virtualbox or Virtual machine or virtual PC.

Single malicious document can expose your whole LAN via ur trusted MFD

1.   "Imagination is the key to Success" in the world of IT....specially applicable to the world of cyber crime....this one i read at one of my fav news feed destinations at http://thehackernews.com...now when we keep covering up the PCs with ideas like antivirus/anti-malware and all sorts of anti's and virus'cides....this thing has come up fresh.....attack the LAN after altering the firmware of the masoom MFD ie multifunction device.Sequence of the main article at http://thehackernews.com is produced below :

- At Chaos Communications Congress (28C3) 

- Ang Cui presents Print Me If You Dare

- He explained how he reverse-engineered the firmware-update process for HPs hundreds of millions of printers

- He showed how he could load arbitrary software into any printer by embedding it in a malicious document or by connecting to the printer online. 

- Performed two demonstrations 

- In the first, he sent a document to a printer that contained a malicious version of the OS that caused it to copy the documents it printed and post them to an IP address on the Internet.

- In the second, he took over a remote printer with a malicious document, caused that printer to scan the LAN for vulnerable PCs, compromise a PC, and turn it into a proxy that gave him access through the firewall.

- Actually found a method to exploit the firmware update capability of certain Xerox MFPs to upload his crafted PostScript code. 

- Was able to run code to dump memory from the printer. This could allow an attacker to grab passwords for the administration interface or access or print PIN-protected documents.

2.  So now start taking care of your firmware updates of your MFDs......

CHROME INSTALLATION ISSUES IN UBUNTU : SOLVED

1. Recently tried installing Chrome browser in Ubuntu 11.10....so I downloaded the .deb file and tried installing it from the terminal via this command

sudo dpkg -i './Downloads/google-chrome-stable_current_i386.deb'

...which showed some error in between installation and came out on the terminal prompt....

2. So googled and found this solution that involves prior installing of few library files as follows :

sudo apt-get install libnspr4-0d libnss3-1d libxss1 libcurl3

this command will install the missing lib files and then on it is the repeat of the earlier command ie

sudo dpkg -i './Downloads/google-chrome-stable_current_i386.deb'

3.   Should solve...let me know if u have any thing unsolved!!!

AVOID OPENING MULTITABS IN BROWSERs

1.  Has it ever happened that you get a mail in one your various Email IDs from Facebook or some other site that you never linked up with....?I am sure if you are a regular browser on social networking sites,this must have happened once...and it must have kept you thinking...HOW ??

2.   This happens when you have that email id open in some other tab and your Facebook account open in other...typically in a multitab session wherein you have opened many sites under one browser in various tabs..... that's when info gathering sites get your email id and things related to their interest.....TAKE CARE

BACTERIA in COMPUTERS

1.  I had heard for so long about Virus'es,worms,trojans................but never heard and read about BACTERIA till recently.....even googled...could not find much except at http://docstore.mik.ua/orelly/networking/

2. Few points about BACTERIA :

- Makes copies of themselves to overwhelm a computer system's resources.

- Also known as rabbits, are programs that do not explicitly damage any files.

- Sole purpose is to replicate themselves.

- May do nothing more than execute two copies of itself simultaneously both of which may copy themselves twice, and so on.

- Reproduce exponentially, eventually taking up all the processor capacity, memory, or disk space, denying the user access to those resources.

- One of the oldest forms of programmed threats.

Download/Upload torrents - Legality Issues in India

1.  Read the following daily life talks in the air now a days :

"Hey did u download Agneepath & TIN TIN....the torrent is available now?"...

"No...its the cam print"..."waiting for the better print...yeah but I have downloaded MI4....the new torrent is crystal clear"

"MS Office 2010 has come and I m already using it on my netbook...& its for free from torrentz..."

...etc...etc...

.......these are few exchange of talks that invariably happens more among the young metro crowd and also getting popular in the Viltro's (Village+Metro)........but did they ever realise the legal aspect of all these talks and downloads? Its time to check all this......RETHINK!!!

2.   Now any one of you reading this and finding himself at some point of time shooting these dialogues at home/office/college should be in  for a shock...because as per the IT act he is a criminal involved in piracy of softwares and movies.

EXTRACT FROM INFORMATION TECHNOLOGY ACT 2000

"Cyber crime is criminal activity done using computers and the Internet. This includes anything from downloading illegal music/movies/softwares files to stealing millions of dollars from online bank accounts. Cybercrime also includes non-monetary offenses, such as creating and distributing viruses on other computers or posting confidential business information on the Internet"

3.  So now that you have read this....the meat is here as follows given in point form for ease of understanding :

- When you download a movie/music/software from a torrent site,you are not only a leecher but at the same time you seed also.A Seed is used to refer to a peer who has 100% of the data.

-  When a leech obtains 100% of the data, that peer automatically becomes a Seed.Seeding refers to leaving a peer's connection available for other peers, i.e. leeches to download from.

- Normally, a peer should seed more data than leech. But, whether to seed or not, or how much to seed, is dependent on the availability of leeches and the choice of the peer at the seeding end.

- Did u understand this much...if not simply put it means that when u download....you upload also at the same time...so u are a illegal downloader and also a uploader of the pirated illegel content.So suppose you have downloaded MI4 or some porn...you are a pretty much proven criminal.If someone gets after you,you are in for real damage.

4. In context of India,though the relevant cyber laws and framework  are ready and already implemented but it will take time to be actually possible for the law to follow each one of them them up individually....thats the only positive side of all illegela downloaders...but there is catch to this...

5. What happens if some other country watches you?....you must be thinking y would some other country watch you downloading agneepath/TIN TIN!!!this is because your uploading may be happening in their country...so all they need is your IP.Thats the end of it.Few major casualties include the famous Lt Col Jagmohan Balbir Singh, who was arrested on May 6 on the charges of circulating child pornography on the internet.The Mumbai Cyber Crime Cell arrested this Lieutenant Colonel from his south Mumbai house for allegedly uploading obscene photographs and video clips involving children on the internet.The German police came across the obscene contents being uploaded on a child pornography site from Mumbai in 2009.So this is where the string of the torrent catches you till end.The german police gave the IP to interpol and he was caught...unawares of what did he actually do?...now it is just unawareness on such issues that such things happen..

6. This time it was a Lt col...next can be any one....u and me....it depends won who is the (un)lucky one...so guys if u r an ardent torrent downloader...think before you do some thing next.....the days are not far when all this will land you up in jail....it is just a matter of time in INDIA..!!

Security Design @ WebHosting

1.  At a time today when new websites are being hosted at quite a pace,proportional is the pace of hacking and defacing of these websites.Today you have a website maker in the market who may simply demand some Rs 500/ per page design and few more hundreds for hosting it...and we all are ready to do pay him....but at what price....is it simply the final handing over taking over of the password that closes the deal between you and the designer/hoster?....NO....I rate it equivalent to the toss....thereon the match begins.....just a matter of time depending on what all security parameters/variables/factors you took into consideration while designing it?

2.  Specially concerned with web sites who have E-Commerce and transactions or who deal with handling database of huge sizes which can be critical later on, if compromised any time.The following factors should be noted down and infact dealt with seriously to be kept on high priority while designing and final hosting :

- Password /Data Protection : You must have a sound password and methods to protect all the DATA in place.

- OS/Server hardening : You use a windows or a linux....rest assured you must always used a hardened OS/Server.

- OS Selection : Create and design on any OS...today you can launch it on web.A more vulnerable OS which has had a history of hacks and known exploits should be avoided.

- DDoS Protection : Shared hosting servers are vulnerable to attacks by hackers who carry out their work by uploading malware or otherwise malicious sites or code onto a server. These malware programs be introduced to a server through security vulnerabilities in a legitimate client’s site, and the malware is used for anything from stealing credit card data to launching a DDoS, or Distributed Denial of Service attack.So think before you fire up your site.

- Spam filters : No explanations

- Firewalls : Must...so many types in market : Decide like what you r going to select a HARDWARE FIREWALL or a SOFTWARE FIREWALL.The selection is of crucial significance in deciding the overall security rating!!!

- BACKUP : You must have a way to keep backing up all your data.Some ploicy should be designed of what happens if owing to some kind of reason you loose all ur data....mirror or offline backup!!!!anything...but keep in mind.

- SSL enabled server : MUST

- SFTP: Though FTP is not that bad....but when SFTP is there....y bank on a relatively lower secured protocol......

SURF SAFE : SURF http'S'

1. In our endeavor to safely surf the web,rest assured ....we will never be safe in recent times to come.But we can always keep improving our surfing habits so that we are not easy victims.

2. Using HTTPS, the computers agree on a "code" between them, and then they scramble the messages using that "code" so that no one in between can read them. This keeps your information safe from hackers.

3.  As on date almost all the browsers offer plugins from their respective web stores that include what I am talking about here ie HTTPS ENFORCER.The HTTPS Enforcer extension makes it easy to ensure you’re connecting to secure sites by rewriting all requests to an HTTPS URL whenever you visit one of the sites HTTPS Enforcer supports.

4.  So install HTTPS plugin for ur respective browser...and SURF SAFE.
