Twitter Trouble

While playing with my new ipad, I can across an interesting article on The Last Watchdog about the US Federal Trade Commission's complaint against Twitter.

I'd read about twitter's security breach in April last year where an employee's personal email account was hacked and provided admin passwords to the social networking site, but had somehow missed the earlier breach where apparently nothng more complicated than a brute force attack revealed the site's weak, lower case, common dictionary word administrative password!

From the article some of the major points from the FTC's complaint are Twtter's failure to:

  • Requiring employees to use hard-to-guess administrative passwords that are not used for other programs, websites, or networks
  • Prohibiting employees from storing administrative passwords in plain text within their personal e-mail accounts
  • Suspending or disabling administrative passwords after a reasonable number of unsuccessful login attempts
  • Providing an administrative login webpage that is made known only to authorized persons and is separate from the login page for users
  • Enforcing periodic changes of administrative passwords by, for example, setting them to expire every 90 days
  • Restricting access to administrative controls to employees whose jobs required it
  • Imposing other reasonable restrictions on administrative access, such as by restricting access to specified IP addresses
Additonally Twitter are "barred for 20 years from misleading consumers about the extent to which it protects the security, privacy, and confidentiality of nonpublic consumer information, including the measures it takes to prevent unauthorized access to nonpublic information and honor the privacy choices made by consumers. The company also must establish and maintain a comprehensive information security program, which will be assessed by an independent auditor every other year for 10 years".

Hackers, Fraudsters and Politicians.

The House Standing Committee on Communications have released the results of their findings into Cybercrime in a report entitled Hackers, Fraudsters and Botnets: Tackling the Problem of Cyber Crime.

I haven't had a chance to digest the near 300-page document yet, but news.com.au has reported some interesting excerpts from it:

Among its final 34 recommendations were:

— The creation of an around-the-clock cyber crime helpline.

— Changes to the law to make unauthorised installation of software illegal.

— Companies who release IT products with security vulnerabilities should be open to claims for compensation by consumers.

That last point seems to be the most potentially controversial and problematic, but I'll hold judgement until I've had a chance to read the entire report...

BYO Forensic Lab

After recently reading and learing about the requirements for setting up a Forensic laboratory, I did a little more research into the subject and came across a fairly recent article on csoonline.com entitled "How to Build Your Own Digital Forensics Lab - for Cheap". While the article is fairly brief and doesn't go into issues such as chain of custody or the capture of volatile data, the author does provide some cool tips on making a usb device read only and points to some free tools for imaging a suspects disk.

The article also has a link to the handy little "Secret Service's Best Practices For Seizing Electronic Evidence, Pocket Guide for First Responders" [pdf] which has tips such as photographing the screen before powering off a suspect machine and performing the power-down by yanking the power cord (and where appropriate removing the battery). For servers in a business it recommends not yanking out the power cord, but calling a pro and restricting access to avoid damaging the system, disrupting legitimate business and (of course!) reducing the potential for officer and department liability.

It's a cool little guide and an intersting insight into law enforcement procedures.

Top 10 Hollywood Stupid Hackers

News.com.au has a fun little gallery on the "Top 10 Hollywood Stupid Hackers" covering films from 'the Net' and 'Firewall' to 'Tron' and 'Jurassic Park'.

They did miss 'Swordfish', which showed that hacking was all about how quickly you can mash the keyboard...

Best quote of the lot: "I shouldn't have written all of those tank programs" by Kevin Flynn (Jeff Bridges) in TRON.

Wii Forensics

A recent article on Networkworld.com mentions how difficult it can be to recover information from smartphones and game consoles.

I can imagine smartphones are particularly difficult, given the constantly changing nature of the hardware in use and the proliferation of mobile operating systems such as Windows Mobile 7, Android, iphone OS, WebOS and BlackBerry OS. The modified or custom file systems can also be challenging as I've read that the xbox360 uses FATX and that the PS3 uses a proprietary version of ext2.

However a particular quote from the article that caught my eye was ""You can take a Wii onto the Internet and it doesn't save sites or browser history....If you type in a Web address and surf, 10 minutes later there's no record of it." Intrigued by this comment, a bit more digging came up with this paper [pdf] on Wii Forensics.

Dr Turnbull highlights the lack of internal storage (excluding the 256MB flash memory) and proprietary file system as being some of the difficulties in Wii Forensic analysis. The paper makes for interesting reading.

Shout outs

A couple of plugs for blogs of friends:

Fellow AISA member Steven Atcheson has recently started his own Information Security related blog blog called 'Keeping it Simple'.

Another friend, Tim Davoren of ENSTOR also has a blog largely based around storage, backup and disaster recovery called Dav's Disorder.

CSIRT

ENISA (The Europrean Network and Information Security Agency) have freely released alot of materials on setting up a CSIRT or CERT.

The step-by-step guide [pdf] seems like a great starting point and they even include exercise materials.

They also have a section on CSIRT-related tools which lists useful tools for every stage of an investigation.
