SQL Injection and Cross-Site Scripting (XSS) are Hot

Custom and automated attacks against web sites continue as vendors and developers still have not gotten the hang of secure coding techniques.

In one case, an automated attack has infected more than 600,000 sites in about two days.

The other, was a case of a targeted attack against MySQL. Interestingly, the attackers are taking credit for this exploit.

Broad automated attacks like the first are usually driven by botnot groups who are ultimately seeking to compromise a large number of end-user systems.

The second attack is becoming less common. My guess, is that they are seeking to establish credibility for their attack skills and to demonstrate their ability to launch a 0-day hack. This sort of activity ranges from the somewhat benign: the hacker equivalent of resume fodder, or more malignantly: demonstrating value before selling their exploits to the criminal underground.

While defects will always exist, it is clear that web site providers still fail to perform the security basics: vetting code before deployment and monitoring their site for compromise.

Current infection counts can be found (for a few of the domains hosting the malicious scripts) with Google:
  1. Lizamoon
  2. Alisa-carter
  3. Alexblane

Registrar's are still a weak link

Very nice article on the hack against Check Free here.

Current theories center on the likelihood that a Check Free employee got suckered by a phishing or straight-up social engineering attack.

I'm going to hazard a guess that this was a spear-phish or more targeted form of attack. A quick search of Linkedin, Facebook and other social networking applications finds a treasure trove of CheckFree/Fiserv employees.

It's a small step to go from these links to a targeted attack against Fiserv IT staff.

However, as the article notes Fiserv was not the only target in this attack and Financial Institutions (FI) are dangerously reliant on a single registrar.

My recommendations:
  1. FI's and others must monitor and protect themselves from domain hijack -- I recommend Pharming Shield.
  2. Get social networking applications out of the data center, IT personnel must not use corporate resources (including email) to access these sites
  3. The Financial Industry is at risk from a single-point of failure at Network Solutions. This must be addressed through community efforts and directly by the platform providers.
Happy Holidays!

Web Site Security Affects You

1987 - Mitnick invades system at Santa Cruz Operation. Santa Cruz police travel to Los Angeles to search apartment where call coming into SCO originates. ( …) Mitnick's representation bargains felony charge down to misdemeanor. Sentence: three years probation.

At SCO, Mitnick found his way in via “war-dialing” onto a UNIX system. Did he crack root? No, root on this system had no password at all… Kevin wasn’t after SCO, he wanted UNIX source so he could get even deeper into Ma Bell’s computers.

20 years later, another hacker discovers a system they can access, only this guy isn’t after big business, he was after YOU.

Last week, Websense discovered that several Super Bowl related web sites had been hacked. According to news reports, these systems were compromised on or before January 26, but engineers at the affected sites were not alerted until February 2nd. For a period of a week, a malware package installed on the victim web server attacked every visitor to the site.

You might not discover “Hackistan” but Hackistan wants to discover you. I intend no offense to my friends from South East Asia, but I like this idea of Hackistan (more on this later).

The crooks are making the Internet their own. Gone are the days when Kids broke into systems to prove their l33t skill, the game is all about money now. And the money is getting very very big.

We can only guess how many systems this attack affected. Enough however, that it appears that the malware server in China was failing under load. Get the irony? The bad guy’s computer was crashing because he had too many victims phoning home.

This hacker was not after fame. No vandalism or political messages, the web sites continued to operate as normal. By the way, I don’t consider people like this to be hackers… this person is a crook, a perpetrator after your login, passwords, credit card info – anything and everything he could get, so he could sell your identity or rip you off directly.

Solution? Simple:

  1. If you have a computer, keep it patched and use a personal firewall.
  2. If you have a web site, monitor the hell out of it.Find someone who will watch your web site and the entire infrastructure it relies on. Don’t settle for a once a quarter/month scan. Find someone who looks at your web site the way the hackers do. Pay them to check it now and check it every day, 365 days a year. This is not a choice any more.
