Lawsuit Against Microsoft and ISPs Filed Over Slammer Damage (30 April 2003)

A Korean civic group has filed a damage suit against Internet service providers (ISPs), the Information Ministry, and Microsoft for damages caused by the outbreak of the Slammer worm in January. The suit, which was filed on behalf of Internet users, Internet salon owners and an Internet shopping mall, alleges Microsoft servers came with security flaws and the company did not inform them of the risks.

Four Students Reach Settlement Agreements with RIAA (1/2 May 2003)

The Recording Industry Association of America (RIAA) has reached settlements with four college students it says were running illegal music file sharing services. The students will each pay the RIAA between $12,000 and $17,500. Attorneys for a Princeton University student involved in the case said their client had reached a settlement with the RIAA but had not admitted guilt.

[Editor's Note (Schneier): The money is trivial (though not to the students involved, most likely), but the precedent is interesting. Looks like the RIAA pushed and they blinked. ]

Microsoft Considering External Patch Testing (30 April 2003)

Microsoft is considering testing patches externally before releasing them to the general public. Because patches are often created very quickly, there is not adequate time to test them for efficacy and to ensure that they do not cause other problems.
-http://www.theregister.co.uk/content/55/30464.html

Majority of Cyber Crime Losses are Due to Data Theft (30 April 2003)

An IBM research report, Information at Risk, suggests that most monetary losses businesses suffer from cyber crime are due not to virus attacks but to data and intellectual property theft. The report, which used data from the UK's National Hi-Tech crime Unit (NHTCU) and the US Computer Security Unit, found that UK companies lost 145 million pounds (approximately $233 million) to cyber crime last year.

Oracle Database Server Buffer Overflow Vulnerability (29 April 2003)

Oracle has released a patch for a buffer overflow vulnerability in all supported versions of Oracle database servers. An attacker could exploit the vulnerability to alter data and to take control of the machine hosting the database server. The vulnerability affects Oracle 7 Release 7.3.x, all released of Oracle 8 and 8i, and releases 1 and 2 of Oracle 9i database. Oracle has released patches for two versions of 9i and one version of 8i, as well as a patch for version 8.0.6.3 for customers with extended maintenance support, but does not intend to release patches for earlier versions.

[Editor's Note (Schneier): So Oracle's "unbreakable" database isn't after all? Imagine our surprise. (Schultz): I presume that Larry Ellison will now retract his statement that this product is hackproof? ]

ISS Confirms Web Hack; Claims It Was A Honeypot (6 May 2003)

A web site offering and delivering free versions of BlackICE to college students was hacked. Shortly thereafter, ISS's Chris Klaus declared that despite its use of a valid ISS domain name and its use for delivering software to students, the system "was not a production system" and was "configured to include numerous vulnerabilities, including several well-known, older vulnerabilities."

Apple Fixes On-Line Store Vulnerability (5 May 2003)

Apple has fixed a vulnerability in its on-line store that could have allowed an attacker to hijack a customer account without knowing anything more than an e-mail address. The flaw was in the part of the store that helps people who have forgotten their passwords; the person who discovered the flaw found that by cutting and pasting a certain hash into another page, he was able to change his password without having to answer the secret question.

Couple Arrested for Allegedly Stealing Credit Reports, Using Info to Make Purchases (1 May 2003)

A woman who worked at Weichert Financial Services in New Jersey and a man she lives with have been charged with using fraudulently obtained credit reports to make Internet purchases.

RIAA Sends Peer-to-Peer Users Warnings by Instant Messaging (29/30 April 2003)

The Recording Industry Association of America (RIAA) has begun sending instant messages to people using Grokster and Kazaa file-sharing services, warning them that they may be violating copyright laws which could result in legal action.

[Editor's Note (Grefer): Instant messaging could also be used by the RIAA to quickly identify which of the nodes previously detected by their bots is currently active ]

New Jersey Institute of Technology Disables Use of Peer-to-Peer Sites (2 May 2003)

In light of the recent actions the Recording Industry Association of America (RIAA) has taken against college students who allegedly ran file swapping sites on school networks, the New Jersey Institute of Technology has disabled the use of peer-to-peer sites on the campus computer network.

Peer-to-Peer Users Block Instant Message Warnings (30 April 2003)

Internet Radio Network Hacked (2 May 2003)

Hackers broke into the computer network of Denver-based Internet radio network w3w3 and stole names and e-mail addresses of 1,000 people who had registered for a cybersecurity conference sponsored by w3w3. Damages were estimated to be more than $50,000; the FBI is expected to investigate.

Klez Still Most Widely Reported Worm; Infections Rates are Down (30 April 2003)

The Klez worm heads the list of Central Command's most reported viruses; however, the overall infection rate has dropped considerably since last April. Klez was followed by Yaha, Sobig and Lovgate. Klez also headed the list from Sophos, followed by Lovgate, Bugbear and Sobig. Sophos has also called attention to the appearance of Datemake, dialer malware that tries to dial up premium phone lines and run up large phone bills.

Remote Users' Anti-Virus Software Not Updated Frequently Enough (29 April 2003)

A Sophos press release expresses concern that businesses are not adequately protecting computers used by remote workers from worms, viruses and other malware. Though 66% of 3,000 businesses polled update their office anti-virus signatures daily, 70% update remote computers' signatures less often than once a week, with 45% updating them once a month. More and more businesses are employing remote workers, which can increase network security risks.

Wisconsin High School Students Investigated for Altering Grades (30 April 2003)

A group of students at Stoughton High School in Stoughton, Wisconsin allegedly bought keystroke logging software for less than $100 on the Internet and used it to break into their school's computer system and alter their grades. Approximately 20 students are being investigated; some have begun suspensions and are awaiting decisions on expulsion.

Pending New Hampshire Legislation Could Make it Harder to Prosecute War Drivers (29 April 2003)

A bill being considered by the New Hampshire state legislature would protect people who access unsecured wireless networks. The legislation would require wireless network operators to secure their networks or lose ground in their ability to prosecute those who access them without permission.

ITAA Survey Says IT Hiring is Likely to Decrease (5 May 2003)

A recent Information Technology Association of America (ITAA) survey of 400 technology and nontechnology hiring managers indicates that IT hiring is likely to stay the same or decrease over the next year. Companies are also increasingly moving some of their operations overseas to save on labor costs.

Study Predicts Significant Growth in Information Security Services Market (29 April 2003)

A study from IDC titled "Worldwide and U.S. Information Security Forecast 2003 - 2007," predicts that the market for information security services will grow to more than $23.5 billion over the next four years, which amounts to more that 20% annual growth.

Overseas Software Development is Cause for Concern (5 May 2003)

Because of the current international security climate, some IT professionals have expressed concern that US companies are outsourcing software development to foreign countries, including India, China and Pakistan, where it is more difficult to assess security risks.
-http://www.computerworld.com/managementtopics/management/
outsourcing/story/0,10801,80935,00.html
[Editor's Note (Northcutt): this really isn't news, but it is a reminder for all of us to consider the risks of outsourcing no matter where it is done. Just prior to Y2K, CIA analyst Terrill Maynard released a report saying that these same countries have an information warfare capability and might insert code during outsourced Y2K remediation.
