What does Microsoft, Twitter, Facebook, NBC, Zen Desk, and Drupal all have in common?They've all been recently hacked.
Yes, hacking is a growing threat for every business both large and small.
Whether it’s stealing private data, taking control of your computer, or shutting down your website, hackers can seriously impact any business, at any time.
Hackers can attack in so many ways, but here’s the ten most popular ways they can threaten the security of your site, and your business:
1. DDOS ATTACK – DISTRIBUTED DENIAL OF SERVICE ATTACK
DDoS, or Distributed Denial of Services, is where a server or a machine’s services are made unavailable to its users.
And when the system is offline, the hacker proceeds to either compromise the entire website or a specific function of a website to their own advantage.
It’s kind of like having your car stolen when you really need to get somewhere fast :P
The usual agenda of a DDoS campaign is to temporarily interrupt or completely take down a successfully running system.
The most common example of a DDoS attack could be sending tons of URL requests to a website or a webpage in a very small amount of time.
This causes bottle-necking at the server side because the CPU just ran out of resources.
Denial-of-service attacks are considered violations of the Internet Architecture Board’s Internet proper use policy,
and also violate the acceptable use policies of virtually all Internet service providers.
2. REMOTE CODE EXECUTION ATTACKS
A Remote Code Execution attack is a result of either server side or client side security weaknesses.
Vulnerable components may include libraries, remote directories on a server that haven’t been monitored, frameworks,
and other software modules that run on the basis of authenticated user access.
Applications that use these components are always under attack through things like scripts, malware, and small command lines that extract information.
The following vulnerable components were downloaded 22 million times in 2011:
Apache CXF Authentication Bypass (http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-3451)
By failing to provide an identity token, attackers could invoke any web service with full permission.
3.CROSS SITE REQUEST FORGERY ATTACKS
A Cross Site Request Forgery Attack happens when a user is logged into a session (or account) and a hacker uses this opportunity to send them a forged HTTP request to collect their cookie information.
In most cases, the cookie remains valid as long as the user or the attacker stays logged into the account. This is why websites ask you to log out of your account when you’re finished – it will expire the session immediately.
In other cases, once the user’s browser session is compromised, the hacker can generate requests to the application that will not be able to differentiate between a valid user and a hacker.
A CROSS SITE ATTACK EXAMPLES
Here’s an example:
<img src=”<span style=”color: red;”>http://example.com/app/transferFunds?amount=1500&destinationAccount=attackersAcct#</span>” width=”0″ height=”0″ />
In this case the hacker creates a request that will transfer money from a user’s account, and then embeds this attack in an image request or iframe stored on various sites under the attacker’s control.
4. SYMLINKING – AN INSIDER ATTACK
A symlink is basically a special file that “points to” a hard link on a mounted file system. A symlinking attack occurs when a hacker positions the symlink in such a way that the user or application that access the endpoint thinks they’re accessing the right file when they’re really not.
If the endpoint file is an output, the consequence of the symlink attack is that it could be modified instead of the file at the intended location. Modifications to the endpoint file could include appending, overwriting, corrupting, or even changing permissions.
In different variations of a symlinking attack a hacker may be able to control the changes to a file, grant themselves advanced access, insert false information, expose sensitive information or corrupt or destroy vital system or application files.
5. SOCIAL ENGINEERING ATTACKS
A social engineering attack is not technically a “hack”.
It happens when you divulge private information in good faith, such as a credit card number, through common online interactions such as email, chat, social media sites, or virtually any website.
The problem, of course, is that you’re not getting into what you think you’re getting into.
A classic example of a social engineering attack is the “Microsoft tech support” scam.
This is when someone from a call center pretends to be a MS tech support member who says that your computer is slow and/or infected, and can be easily fixed – at a cost, of course.
