UK Information Commissioner Will Serve Enforcement Notices on HMRC and MoD (June 25, 2008)

Following the release of a verdict from the Independent Police Complaints Commission, a report from Pricewaterhouse Coopers chairman Kieran Poynter regarding the HMRC data loss incident, and a report from Sir Edward Burton regarding the incidents at MoD, UK Information Commissioner Richard Thomas says his office will serve enforcement notices on HM Revenue & Customs (HMRC) and the Ministry of Defence (MoD) for "deplorable failures" at both departments that led to violations of the Data Protection Act. Last year, HMRC acknowledged the loss of computer disks containing personally identifiable information of 25 million families; MoD acknowledged that it lost a number of laptops, one of which contained sensitive data of 600,000 recruits. Compliance with the enforcement notices will include implementing all recommendations made. The departments will be required to submit annual progress reports for the next three years.

Senate Subcommittee Hearing Focuses on CBP Seizure of Electronic Devices (June 24 & 25, 2008)

The US Senate Judiciary Committee's Subcommittee of the Constitution, Civil Rights and Property Rights heard testimony regarding the US Customs and Border Protection (CBP) search policies that have allowed the search and seizure of personal and work laptops and other electronic devices at US borders. While some maintain that laptops are no different from luggage, others contend that the practice is unlawful, as the devices have been seized without probable cause. Earlier this year, the 9th Circuit Court of Appeals ruled that CBP does not need reasonable suspicion to conduct the searches. Electronic Frontier Foundation Lee Tien senior staff attorney said his organization "does not dispute that the Fourth Amendment works differently at the border, but 'differently' does not mean 'not at all.'"

(Honan): An interesting side effect of the CBP search policies is that many companies are now rethinking how best to protect sensitive data for mobile users. It is ironic though that it is the threat of a US government agency accessing a company's sensitive data that is driving this corporate rethink and not the threat of criminals getting their hands on the same information. ]

Privacy Officers and Marketing Depts Have Different Ideas About Data Security (June 23, 2008)

A study from the Ponemon Institute reveals a disconnect between what privacy and security officers believe about the level of protection afforded customer data and what the marketing department is actually doing with the data. Eighty percent of respondents from marketing departments said their companies share customer email addresses with third parties, while just 47 percent of security and privacy officers said they shared email addresses. Twenty-nine percent of marketing respondents said they believe their companies share Social Security numbers, while just seven percent of privacy professionals said their companies shared that information. There is no reason to believe that conflicting responses came from within the same company, but the general trend is worrisome. The study was funded by Strongmail.

0623privacy_print.html

[Editor's Note (Schultz): The results of this study are fascinating. It is easy to be lulled into believing that data protection is far better than it actually is. The solution is systematic and thorough compliance enforcement, something that is for the most part missing or deficient in many organizations. ]

Former Employee Allegedly Deleted Organ Bank Data (June 26, 2008)

Danielle Duann has been indicted for allegedly breaking into the computer system at an organ bank and deleting patient data. Duann allegedly accessed the LifeGift Organ Donation Center database shortly after she was fired from her position as technology director at the Houston, TX organ bank, despite the fact that her administrative rights and passwords were revoked upon her termination. She then allegedly deleted database records and accounting invoice files. The lost data were restored from backups. If she is convicted, Duann could face up to 10 years in prison and a US $250,000 fine.

SPYWARE, SPAM & PHISHING

Charter Communications Suspends NebuAd Pilot (June 25 & 26, 2008)

Charter Communications says it has suspended its planned pilot of the NebuAd online behavioral advertising system. NebuAd has come under increased scrutiny and criticism for unauthorized deep packet modification and other questionable means of tracking consumer behavior. Charter said that if it uses NebuAd in the future "it should be on the basis that NebuAd will not intercept customers' data and plant false code in it."

[Editor's Comment (Northcutt): we wrote a short course once at SANS, titled Staying Invisible on the Internet. No one ever signed up for it. People even asked, "why would I take the course unless I had something to hide". For the life of me, I do not understand why people tolerate total invasion of personal privacy, but they do. That means NebuAd did not succeed with this one ISP, but mark my words, unless we educate people and explain why privacy is a good thing, they will. The Wikipedia article has a list of ISPs using or considering deploying NebuAd in case you think Charter is the only one:

WORMS, ACTIVE EXPLOITS, VULNERABILITIES & PATCHES

Two IE Flaws Discovered (June 26, 2008)

Two flaws in Internet Explorer (IE) have been discovered. The first is a cross-site scripting flaw in IE6 in the form of a validation error when the browser handles the "location" or "location.href" property of a window object. Until a fix is available, users should disable scripting in IE6 or upgrade to IE7. The other flaw affects IE7 and is a spoofing vulnerability.

Microsoft Issues List of Tools to Help Protect Sites from SQL Attacks (June 24 & 26, 2008)

Microsoft has issued a security advisory regarding the recent escalation of SQL injection attacks. The "attacks do not exploit a specific software vulnerability, but instead target web sites that do not follow secure coding practices for accessing and manipulating data stored in a relational database." The advisory includes a list of suggested tools to help administrators protect their sites.

ATTACKS, INTRUSIONS, DATA THEFT & LOSS

Marshall Islands Cut Off From Incoming eMail by DDoS Attack (June 25 & 26, 2008)

A distributed denial-of-service (DDoS) attack on the Marshall Islands' only Internet service provider (ISP) left the tiny country without the capability to receive incoming email. While messages can be sent between National Telecommunications Authority (NTA) customers, mail from other ISPs is still not making its way to NTA customers. NTA general manager Anthony Muller servers would be added to help prevent a recurrence. The attack began on Tuesday and it could be days before the system is back to normal.

STATISTICS, STUDIES & SURVEYS

Ten Networks Account for Nearly Half of All Malicious Sites (June 25, 2008)

Analysis of more than 213,000 sites hosting malware found that more than half are running under Chinese IP addresses. The analysis was conducted by Stopbadware.org, which acknowledged that it couldn't say how many of the sites are deliberately serving malware and how many are legitimate sites that were infected. The total number of malware-infected sites detected is up 300 percent over last year. Stopbadware.org manager Maxim Weinstein says that the increase could be attributed in part of increased efforts to find malicious sites, but that other statistics cited by other groups recently indicate the likelihood that malware infection is on the rise, likely because of SQL attacks. The US network spreading the most malware is Google, which is a Stopbadware.org sponsor and the source of the analyzed data. In addition, just 10 networks hosted nearly half of the sites. They acknowledge that Google bots searching for malware are concentrating on Chinese servers, which could also explain the results.

[Editor's Note (Ranum): According to Chinese Government announcements, the internet population of China is about the same as that of the US, or higher. And, because unlicensed copies of Windows are prevalent, and patches are not available, we predict that the number of vulnerable systems and websites in China is probably the highest in the world. Thus, simple demographics argues that a majority of jump-off points for mal-hosting and attacks will originate in China. What is less clear is whether the people behind the systems and sites are in China, or not.
(Cole): The key lesson is that if you block a small subset of sites that your organization does not need, you can go a long way to block malicious content from coming into your site. You should also check Incident Storm Center (incidents.org) on a regular basis to update your IP block list. ]

Dutch Government Wants to Halt Publication of Mifare Flaw Paper (June 25, 2008)

Dutch government officials have called on researchers at Radboud University to not publish a paper detailing security flaws in the Mifare RFID chip used in the UK's Oyster prepaid public transportation smartcard. The chip was also being used in a Dutch travel system card; that project has been postponed. One of the researchers said that the content of the paper is not attack code, but acknowledged that other groups may have begun developing exploit code. "Killing the messenger does not solve the problem," said researcher Bart Jacobs. "This paper serves the interest of our society."
