Volume X - Issue #4

January 15, 2008


Two great reads, an apology and a process:
Interesting articles: (1) One of the Storm Center handlers, Maarten Horenbeck, wrote a great article about targeted attacks http://isc.sans.org/diary.html?storyid=3835 . Johannes Ullrich recommend it saying, "It is way better than anything else I have seen about these attacks.
(2) And Mike Assante (ex CSO of AEP and now with Idaho National Labs) wrote a paper on parallels between today's cyber vulnerabilities and vulnerabilities in the aqueducts of Rome.
http://www.inl.gov/nationalsecurity/energysecurity/d/infrastructure_protection_i
n_the_ancient_world.pdf

(3) A sincere apology to the security managers who were frustrated by my comment in the last issue about people who write security policies that are never fully implemented. That note broke SANS' cardinal rule of never pointing out a problem without offering a solution. Here's how security managers who get their policies implemented do it: They select the policies that really matter (the ones that are most important for blocking active attacks.. secure configuration is a good place to start) and they publish monthly color charts comparing the organization's divisions using metrics that measure compliance with the policies. They give the charts to top management and the executives make sure the laggards catch up using peer embarrassment.

Mass Web Attack Confounds Law Enforcement and Researchers (14 - 7 January 2008)

A massive attack has compromised tens of thousands of web sites, each of which infects visitors with a bevy of exploits including javascrip generated in real time. Forensics are "extraordinarily difficult," says one researcher. Web application vulnerabilities - basically programming errors that allowed SQL injection attacks - accounted for a portion of the infected sites.

LEGAL MATTERS

Convicted Database Hacker Arrested for Alleged Extortion (January 14, 2008)

Jeffrey Robert Weinberg, who last year was convicted of breaking into the Accurint database, has been arrested again, this time for allegedly taking control of an Internet celebrity's MySpace account. A woman known online as Amor Hilton reportedly was locked out of her MySpace account at the end of December and shortly thereafter began receiving phone calls demanding photographs and other activity in exchange for control of her account. Weinberg received a 10-month sentence for the Accurint hack and was released in November to serve three years of supervised release.

Former Cox Employee Gets Prison Time for Causing Outage (January 10, 2008)

William Bryant has been sentenced to five months in prison and five months of home confinement for sabotaging his former employer's computer system. He was also ordered to serve two years of supervised release, perform 200 hours of community service, and pay more than US $15,000 in restitution. Bryant worked at Cox Communications, which provides computer and telecommunications services across the US. When Bryant was asked to resign from Cox, he remotely shut down parts of the company's network, which resulted in loss of services to customers in Texas, Las Vegas, New Orleans, and Baton Rouge. In some cases, 911 emergency services were affected as well. The services were back up within hours of the attack.

[Editor's Note (Skoudis): When we perform security assessments and penetration tests, we sometimes find companies that send sensitive information in clear text across the Internet, from corporate network to corporate network. When we tell them about the risk, they sometimes respond, "But, only the ISP would see that data, so it's not a big deal." As much as we all love our ISPs, don't assume that data going across their network in clear text is safe. It's not. An attacker could redirect the flow, or an unscrupulous ISP employee could intercept it. In this case, the employee impacted availability, but an ISP employee could likewise undermine confidentiality and integrity if you aren't careful. ]

HOMELAND SECURITY & GOVERNMENT SYSTEMS SECURITY

TSA Website Exposed Passenger Data (January 11, 2008)

A congressional investigation found there were security problems with a Transportation Security Administration (TSA) website created to allow people to petition the government to have their names removed from no-fly lists. Nearly 250 people who submitted personal details, including Social Security numbers (SSNs), may be at risk of identity theft. The problem affects people who submitted information to the site between October 6, 2006 and February 13, 2007. An information security graduate student discovered the problem while researching boarding pass security early last year. The security problems include the fact that the site was not hosted on a .gov domain, the home page was unencrypted, as was one data submission page, and the pages that were encrypted were not properly certified. The overall appearance of the site, with misspellings and lack of security, made it easy to mistake for a phishing site. TSA took down the site shortly after the graduate student made his finding public.

Wisc. State Agency to Drop SSNs as Unique Identifiers (January 8 & 10, 2008)

Wisconsin's Department of Health and Family Services will start using randomly generated identification numbers in place of SSNs sometime later this year. The change will affect residents who receive Medicaid and those receiving state-funded disability payments. Just last week, a contractor for the department had printed and mailed newsletters to 260,000 Medicaid recipients with their SSNs on the mailing labels. About 240,000 more newsletters with SSNs visible were prevented from being mailed after the department became aware of the problem. A similar incident occurred about a year earlier.

WORMS, ACTIVE EXPLOITS, VULNERABILITIES & PATCHES

Malware Hiding on Digital Devices (January 9 & 13, 2008)

There have been three reports of consumers who found that digital picture frames attempted to install malware on devices connected to the frame. The frames were sold in different branches of the same store, suggesting that the source of the infection was the factory or some point during shipping. The malware appears to be a Trojan horse program that hides itself like a rootkit once on a computer and tries to disable the computer's ability to access anti-virus tools. The incidents illustrate the necessity for users to be wary of all digital devices with onboard memory. There have also been reports of hard disk drives and digital music players attempting to install malware on computers. These incidents appear to have been accidental, related to the manufacturing process, but some believe it is just a matter of time before such infections are intentional and malicious. It is also possible that the items were purchased and returned, which would make it possible for someone to install malware on a device and then return it.
-http://www.securityfocus.com/news/11499
-http://www.pcworld.com/article/id,141295-pg,1/article.html
[Editor's Note (Ullrich): There have been more than three reports. In some cases, devices came fresh out of the box, in other cases the device was infected by a prior owner, returned and then sold again as refurbished.
(Skoudis): This is pretty serious stuff, but is only coming to light because the media covers it when it impacts consumers. The risk is even greater for business and government procurement of digital devices. ]

Network-Connected Printer Vulnerability (January 9, 2008)

Proof-of-concept code demonstrates how attackers could target network-connected printers with spam. The idea is based on cross-site scripting and could be manipulated to send spam to the printer of someone who visits a maliciously crafted website, or a website vulnerable to cross-site scripting. According to a paper published in November, "many network printers listen on port 9100 for a print job. You can telnet to the printer port and enter text. Once you disconnect from the printer it will print out the text that you send it." The attack could also be used to tell the printer to send a fax, format its hard drive or download firmware. Printers plugged directly into PCs are not vulnerable to the attack. Defensive actions include setting administrator passwords for printers and restricting printer access so that it will only accept jobs from specific servers.

-http://aaron.weaver2.googlepages.com/CrossSitePrinting.pdf
[Editor's Note (Skoudis): Once inside a corporate network, printers offer an attacker (a bad guy or penetration tester) an excellent platform from which to scan or launch further attacks. Printers get far less scrutiny from system and network administrators, and are often wide-open.
(Liston): Several years back, a company I was working for sat on the same class B as another company that was riddled with infected machines and constantly beating on our firewall. They also had a printer open to the world. Phone calls and emails failed to get anyone's attention, but when I mapped their printer and dumped out a nicely formatted anonymous letter telling them to clean up their act (and informing them that their printer was available to anyone on the Internet) things immediately got better. I always wondered when spammers would figure this out... ]

ATTACKS, INTRUSIONS, DATA THEFT & LOSS

Polish Teen Faces Charges for Allegedly Manipulating Train System (January 11, 2008)

A 14-year-old Polish student is facing charges of endangering public safety for allegedly manipulating the tram system in the city of Lodz with a modified television remote control device. Four trams were derailed as a result of the activity, injuring 12 people. The teenager allegedly modified the remote control device to allow him to change the tracks and control track junctions. The incident illustrates the apparent lack of security of some infrastructure systems. The teenager will face charges in a juvenile court.

Barclays Chairman Victim of Identity Theft (January 10 & 11, 2008)

Barclays Bank chairman Marcus Agius has become the victim of an identity thief. Someone obtained sufficient personal information about the chairman to convince the bank to issue a new card in Agius's name. The thief then used the card to withdraw GBP 10,000 (US$19,574) from Agius's account. The bank has reimbursed the chairman for his losses and established procedures to ensure that the same thing does not happen again.

[Editor's Note (Schultz): I am not kidding when I say that Barclays Bank senior management at Barclays Bank could not have had a better information security-related wake-up call. Being a victim does wonders in sensitizing individuals to the reality of risk.]

Stolen Laptops Hold Nashville Voter Data (January 3, 2008)

Two laptop computers stolen from the Metro Office Building in Nashville, Tennessee, hold the SSNs of approximately 337,000 Nashville voters; the data are not encrypted. The break-in was discovered after a security guard noticed the building was unusually cold; the thieves had broken a window to gain access to the building. The video recorder that could have captured evidence had been unplugged. The guard who was on duty at the time of the theft has been fired. The Davidson County Election Commission and two other departments questioned by the Metro Council's Public Safety Committee about the incident say they have stepped up physical security and have removed voters' SSNs from laptops. Alarms have been placed on video recorders to alert staff. There is some confusion as to whose responsibility it was to encrypt the data. The election commission plans to establish a procedure for making sure laptops are secured after business hours. The Davidson County Election Commission is offering free identity theft protection to affected voters.

MISCELLANEOUS

Washington Post Writer Details Experience with ID Theft (January 13, 2008)

Washington Post personal finance writer Nancy Trejos relates her experience as the victim of identity theft. She describes what she was required to do to protect her account and credit. First she had to file a complaint with the Federal Trade Commission (FTC) and present it to the police. When she contacted the credit bureaus to place a fraud alert on her credit file, she was given a choice of a renewable 90-day alert or a seven-year alert. When placing an alert on a credit file, just one bureau needs to be contacted and that bureau informs the others. However, if a victim wants to place a credit freeze on the files, each of the three bureaus must be contacted separately. In addition, the officer she spoke to asked her if she had verified the identity of the person from the card company who had called her and alerted her to the fraud in the first place - pointing to the possibility that this could be another avenue for thieves to gather valuable personal and financial information. Another important fact to know is that credit cards offer greater protection from losses than do debit cards.
-http://www.washingtonpost.com/wp-dyn/content/article/2008/01/12/AR2008011200275_
pf.html

[Editor's Note (Honan): A growing concern I have is where people are classifying most online fraudulent activities as identity theft. Unauthorised use of a credit card is not identity theft. It is simply credit card fraud. Credit card fraud, as the article points out, results in limited liability to the victim, whereas identity theft has far more serious repercussions as in the previous story --Barclays Chairman Victim of Identity Theft. If we continue to categorise everything as identity theft we run the risk of minimising the seriousness of this type of crime. ]

US-CERT Recommends Disabling Unnecessary Browser Features (January 11, 2008)

The US Computer Emergency Readiness Team (US-CERT) says that many browsers offer increased functionality that may actually be unnecessary for most users and could present vectors of attack for cyber criminals. US-CERT recommends disabling several features including JavaScript, Java and ActiveX controls, plug-ins, cookies, and pop-up windows, unless users feel they are specifically necessary.

-http://www.us-cert.gov/cas/tips/ST05-001.html
[Editor's Note (Skoudis): I try to make sure my security recommendations are reasonable, especially when directed at non-technical consumer-type users. These recommendations are hardly reasonable for 99% of users on the Internet. Disable cookies? Yeah, right. They'll do it for one minute, realize that all of their apps are broken, and then back out _all_ of the other hardening recommendations included in this list. ]

Infrastructure Protection Lessons From the Roman Aqueducts

Michael J. Assante's paper, "Infrastructure Protection in the Ancient World," looks to the Roman Aqueducts to gain insight into the development of critical infrastructure protection, particularly that of our modern electric power grid. He observes that "infrastructures can change from simple conveniences or enabling capabilities to critical necessities relatively quickly once they are put in place." The ancient Romans built their early Aqueducts with protection in mind so their enemies could not disrupt their water supply. When they had gained prominence and were no longer as fearful of physical attacks on the Aqueducts, they built them in a way to show their power, which ultimately gave enemies a way to cut them off from essential provisions.

A need for increased visibility into its diverse network prompted GraceKennedy's security team to seek an intrusion detection system. They found a solution that met all their needs and offered great tech support, as well as a component that could establish a network activity baseline and another that included a top vulnerability scanner for the same price as other solutions they tried. GraceKennedy is one of the Caribbean's largest and most dynamic corporate entities. The company started in Jamaica in 1922 as a small trading establishment and wharf founder. It has expanded and diversified over the years, changing from a privately-owned enterprise to a public company listed on the stock exchanges of Jamaica, Trinidad, Barbados and the Eastern Caribbean. Today, the GraceKennedy Group comprises a varied network of some 60 subsidiaries and associated companies located across the Caribbean, in North and Central America and the United Kingdom. The group's operations span the food distribution, financial services, insurance, remittance, hardware retailing and food-processing industries.
