Millions of Blogs Inaccessible Due to DDoS Attack (4 May 2006)

A "massive" distributed denial-of-service (DDoS) attack on Six Apart's blogging services and corporate web site left about 10 million LiveJournal and TypePad blogs unreachable for hours on Tuesday, May 2. Six Apart plans to report the attack to authorities.

Soon-to-be-Proposed Digital Copyright Legislation Would Tighten Restrictions (24 April 2006)

Despite efforts of computer programmers, tech companies and academics to get Congress to loosen restrictions imposed by the Digital Millennium Copyright Act (DMCA), an even more stringent copyright law is expected to be introduced soon. The Intellectual Property Protection Act of 2006 would make simply trying to commit copyright infringement a federal crime punishable by up to 10 years in prison. The bill also proposes changes to the DMCA that would prohibit people from "making, importing, exporting, obtaining control of or possessing" software or hardware that can be used to circumvent copyright protection.

Defense Security Service Temporarily Stops Issuing Clearances (2 May/29 April 2006)

Citing a high volume of applications and a lack of funding, the Defense Security Service has announced that it will temporarily stop issuing contractor security clearances. An increased demand for personnel with security clearances has led to a large backlog of unprocessed applications for clearance. Contractors may be asked to assume some of the costs of processing the security clearance applications. Information technology industry groups have lobbied Congress to address the issue soon; the Information Technology Association of America has asked that Congress pass legislation requiring the Defense Security Service to resume processing clearance applications and to provide funding through a supplemental budget bill.


[Editor's Note (Weatherford) This will exacerbate an already critical problem. For several years, defense contractors have had to bear the burden of delays by DSS in the processing of security clearances and this has had a significant impact on many programs since without a clearance, people can't work. A lot of small businesses simply can't afford to hire people and carry them as overhead until DSS gets around to processing a clearance. ]

Air Force Victorious in Sixth Annual Cyber Defense Exercise (1 May 2006)

Five military academy teams took part in the sixth annual Cyber Defense Exercise (CDX), a four-day competition that involves defending specially constructed computer networks against attacks staged by a team of National Security Agency (NSA) and Defense personnel. The teams, from the Air Force, Coast Guard, Merchant Marine, Naval academies and the US Military Academy at West Point, were scored on the security of their networks as well as on keeping their networks operational. The Air Force Academy took first place in the competition, which ran from April 10-13.

[Editor's Note (Paller): Kudos to all the participants, and especially NSA for making it happen. I watched some of the process and interviewed participants. The learning and discovery that goes on was wonderful. The only sad element was that the Naval Post Graduate School didn't engage this year (I think they lost last time), so on the graduate level, the Air Force Institute of Technology had the field to itself. It was a dominating performance by the Air Force- undergraduate and graduate. (Guest Editor Tim Rosenberg): Congratulations to the Air Force Academy. Exercises such as the CDX are an essential part of security training and education. The gaming environment provides a safe place for people to truly test their security knowledge and expertise without risking production systems, live customer data or their jobs. The success of the CDX over the years has led to several competitions involving public sector universities; most notably the National Collegiate Cyber Defense Competition recently held at University of Texas, San Antonio. ]


FTC Cases Against Alleged Spyware Operations Proceeding (4 May 2006)

The US Federal Trade Commission sued two alleged spyware operations, alleging unfair and deceptive practices in violation of federal law. Both were accused of taking control of users' computers without permission and subjecting the users to a barrage of pop-up advertisements. Smartbot.Net and its affiliate OptinTrade were ordered to forfeit more than US$4 million in profit. Odysseus Marketing "has been barred from collecting consumers' personal data pending trial."


MySQL Database Update Addresses Handful of Flaws (4 May 2006)

A patch released this week for the MySQL database addresses several flaws that could be exploited locally and remotely. The flaws have been assigned a severity rating of "moderate." The update, MySQL 5.0.21, addresses vulnerabilities that exist in versions 4.0.26, 4.1.18, 5.0.20, 5.1.9 and earlier.

Critical Flaw Found in X Window System (4/3/2 May 2006)

A critical buffer overflow flaw in the X Window System code could be exploited to give local users the ability to overwrite system files and launch denial-of-service attacks. The flaw is attributed to a missing parenthesis and was found as part of a Department of Homeland Security (DHS) funded project. The vulnerability affects X11R6.9.0 and X11R7.0.0.

Mozilla Issues Update for Firefox (2 May 2006)

Mozilla has released a Firefox update that addresses a recently reported flaw in the way it handles certain "contentWindow.focus()" JavaScript code. The flaw could be exploited to crash vulnerable browsers and potentially fool the browser into running malicious code. Users can disable JavaScript handling in Firefox as a protective measure. The flaw does not affect Firefox 1.0 or Mozilla Suite 1.7.


Ohio University Acknowledges Computer Breaches (3/2 May 2006)

Ohio University has acknowledged two apparently unrelated computer security breaches. An intrusion at a database server that holds information belonging to more than 300,000 people affiliated with the Athens Ohio-based school exposed approximately 137,800 Social Security numbers (SSNs). IT officials became aware of the breach when they discovered the server was being used to conduct a denial-of-service attack. Logs indicate the server was breached as far back as 2005 from IP addresses in the US and abroad. This particular server was scheduled to be decommissioned over a year ago; because IT personnel believed it was no longer on line, it had not been patched. A second breach involved a server at the school's Technology Transfer Department. The FBI is investigating both incidents.
[Editor's Note (Schultz): It is lamentable that an incident that occurred last year was not discovered until recently, yet this is by no means a rare development. Many organizations' incident detection capabilities, if they exist at all, are terribly deficient. ]

UK Retailer Source of Credit Card Data Theft (28 April 2006)

An unnamed UK retailer has been identified as the source of a security breach that has resulted in the reissue of at least 4,000 MasterCard and Visa credit cards. At least three card issuers, the Clydesdale bank, Morgan Stanley and Goldfish, which is part of Morgan Stanley, have begun informing their affected customers of the breach and issuing then new cards. MasterCard would not name the retailer to whom the breach was traced. but insisted that MasterCard systems were not breached. Visa also notified card-issuing entities as soon as it became aware of the breach. In a separate story, UK companies are under no legal obligation to inform their customers when their personal information is compromised in a security breach.

Man Charged with Illegally Accessing County Computer System (27 April 2006)

A Pennsylvania man has been charged with various computer crimes, including unlawful use of a computer, for illegally accessing the Lancaster County Computer Assisted Dispatch site. Duane Kline, who is a lieutenant with the West Hempfield Fire and Rescue Company, allegedly used the East Hempfield Township Police Department login and password to access police intelligence and investigative information while at his job at Northeast Agri Systems.


Laptops are the Latest Card Theft Tools (3 May 2006)

As modern cars are increasingly protected by software, car thieves are exploring a new vector of attack - laptop computers. Some cars no longer require a key to start. Software programs can be used to gain access to cars' computers, open doors and start engines. The information is supposed to remain in the hands of locksmiths and car manufacturers, but persistent thieves will find a way to obtain what they seek.

[ Editor's note ( Northcutt): The most interesting line in the article is "While automakers and locksmiths are supposed to be the only groups that know where and how security information is stored in a car, the information eventually falls into the wrong hands." Security through Obscurity anyone? A similar article with more specifics can be found at:

Schools' Eyes Opened to Computer Security Threats (29 April 2006)

Boston area public school systems have started taking steps to secure their computer systems following a number of incidents that illustrated the dangers inherent in lax policies. Boston Public Schools stepped up security measures after a student at Boston Latin School accessed a teacher's computer and viewed student records and tests. Two Brookline High students were suspended for accessing the school's computer system and altering grades; teachers at the school are now required to make their passwords more difficult to guess. A Lexington High student was investigated last year for allegedly altering his attendance records.

[Editor's Note (Grefer): The schools would be well advised to use any one of the various password cracking utilities to verify passwords' strength. (Schultz): Making passwords more difficult to guess will do some, but not all that much good. The problem is with passwords, credentials that date back almost to the advent of computers, as the basis for authentication. The technology of breaking passwords and of stealing them is now far ahead of the value that they deliver. Administrators for these school systems would thus be well-advised to look into cost effective alternatives to password-based authentication. ]

Professional Security Certification Comparison And Assessment (4 May 2006)

The GIAC Advisory board has been helping Stephen Northcutt work on a document comparing the various certifications. This is not meant to be a marketing tool, but rather something to help cluster apples with apples and oranges with oranges. We seek reviewers willing to provide substantive, considered advice, to make it the best tool possible. If you hold one or more certifications and are willing to review and provide feedback please contact for a copy of the spreadsheet.
