Through the next query, we will try to fetch table name inside the database union select 1,table_name,3 from information_schema.tables where table_schema=database() limit 0,1įrom the screenshot you read can the name of the first table is artists. Here we have retrieve 5.1.73 0ubuntu0 10.04.1 as version and as the current user Next query will extract the current username as well as a version of the database system union select 1,version(),current_user() Use the next query to fetch the name of the database union select 1,database(),3įrom the screenshot, you can read the database name acuart Hence you can see now it is showing the result for the remaining two tables also. Now try to pass wrong input into the database through URL by replacing artist=1 from artist=-1 as given below: union select 1,2,3 union select 1,2,3įrom the screenshot, you can see it is show result for only one table not for others. Let’s penetrate more inside using union base injection to select statement from a different table. Similarly repeating for order 2, 3 and so on one by one order by 2įrom the screenshot, you can see we have got an error at the order by 4 which means it consists only three records. Now using ORDER BY keyword to sort the records in ascending or descending order for id=1 order by 1 In the given screenshot you can see we have got an error message which means the running site is infected by SQL injection. Now use error base technique by adding an apostrophe ( ‘) symbol at the end of input which will try to break the query. So here we are going test SQL injection for “ id=1″ Open given below targeted URL in the browser We are going to apply the same concept and techniques as performed in Dhakkan on a different the platform Today we are again performing SQL injection manually on a live website “ ” in order to reduce your stress of installing setup of dhakkan. Not sure how much involvement you have in desin besides DB but protect yourself by showing you are unwilling to accidently expose customers, you know people love scapegoates.This article is based on our previous article where you have learned different techniques to perform SQL injection manually using dhakkan. And disable accounts that fail multiple times for sure so brute force or guessing attacks fail.ĥ) Even when confirming data make sure you do not display the entire value just maybe the last 4-5. And have a valid certificate as well as use only SSL on the server.Ĥ) Consider requiring changing passwords on that system often or at least complex passwords. As well, the SQL Server should talk multiprotcol for encryption. Fed gov won't take lightly to you failing to protect the customer.ģ) For more protection if web based do not have the SQL Server running on the same box as the Web server and do your best to harden the system against attacks. But you should take care not to store unencrypted just in case you are ever compromised.

Still, plenty of people have no problems storing it as various numeric datatypes, so figure out what works best for your situation.ġ) There are some simple checks you can do without LUHN such asĢ) You are dealing with sensetive data which needs to be protected, I would store as maybe a varchar(100) and use a one way protection scheme (using CAPICOM APIs is easy enough) to encrypt the data you store against say the users password or other unique data. It just seems to me that I need to convert less often when I'm working with varchar than with a numeric data type. Also, you use a substring to determine card type, length to validate proper number of digits for the type, and substring (or right) to grab the check digits.

While the mod 10 validation does perform numerical calculations, you use substring functions to pull out those digits. That's not to say that Ninja's RGR'us doesn't have a point, as that could easily change tomorrow. Visa starts with 4, most Discover cards start with 6011, etc. Although currently no major credit cards begin with zero, they actually all have initial numeric sequences by which you can identify the card type. in varchar columns. We don't store any hyphens, spaces, etc., as we always do a lot of pre-processing on the number prior to authorization anyway, most of which is string manipulation, so formatting it after that is a piece of cake. By the same token, I store phone numbers, SSNs, zip/postal codes, etc. For a variety of reasons, we've always stored them as varchars, but mostly because I've always stored numbers that weren't used for calculations that way.
