It’s nigh on impossible to make a system completely secure from outside threats, especially if it’s going to be available to the general public. Still there are certain measures you can take that will make it a lot harder for a would be attacker to get at your users’ private data, which is usually enough for them to give up and move onto another more vulnerable target. However, as my previous posts on the matters of security have shown, many companies (especially start ups) eschew security in favor of working on new features or improving user experience. This might help in the short term to get users in the door, but you run the very real risk of being compromised by a malicious attacker.
The attacker might not even be entirely malicious, as what appears to be the case with one of the newest hacker groups who are calling themselves LulzSec. There’s a lot of speculation as to who they actually are but their Twitter alludes to the fact that they were originally part of Anonymous, but decided to leave them since they disagreed with the targets they were going after and were more in it for lulz than anything else. Their targets range drastically from banks to game companies and even the USA senate with the causes changing just as wildly, ranging from simply for the fun of it to retaliations for wrong doings by corporations and politicians. It would be easy to brand them as anarchists just out to cause trouble for the reaction, but some of their handiwork has exposed some serious vulnerabilities in what should have been very secure web services.
One of their recent attacks compromised more than 200,000 Citibank accounts using the online banking system. The attack was nothing sophisticated (although authorities seem to be spinning it as such) with the attackers gaining access by simply changing the identifying URL and then automating the process of downloading all the information they could. In essence Citibank’s system wasn’t verifying that the user accessing a particular URL was authorized to do so, it would be like logging onto Twitter and then typing say Ashton Kutcher’s account name into the URL bar and then being able to send tweets on his behalf. It’s basic authorization at its most fundamental level and LulzSec shouldn’t have been able to exploit such a rudimentary security hole.
There are many other examples of LulzSec hacking various other organisations with the latest round of them all being games development companies. This has drawn the ire of many gamers which just spurred them on to attack even more game and related media outlets just so they could watch the reaction. Whilst it’s kind of hard to take the line of “if you ignore them they’ll go away” when they’re unleashing a DDoS or downloading your users data the attention that’s been lavished on them by the press and butthurt gamers alike is exactly what they’re after, and yes I do get the irony of mentioning that . Still had they not been catapulted to Internet stardom so quickly I can’t imagine that they would continue being as brash as they are now, although there is the possibility they might have started out doing even more malicious attacks in order to get attention.
Realistically though the companies that are getting compromised by rudimentary URL and SQL injection attacks only have themselves to blame since these are the most basic security issues that have well known solutions and shouldn’t pose a risk to them. Nintendo showed that they could withstand an attack without any disruptions or loss of sensitive data and LulzSec was quick to post the security hole and then move onto to more lulzy pastures. The DDoSing of others though is a bit more troublesome to deal with, however there are many services (some of them even free) that are designed to mitigate the impact of such an incident. So whilst LulzSec might be a right pain in the backside for many companies and consumers alike their impact would be greatly softened by a strengthening of security at the most rudimentary level and perhaps giving them just a little less attention when they do manage to break through.
