White House Revises PDD-63 (7 November 2003)

The Bush administration plans to release its version of President Clinton's Presidential Decision Directive-63 (PDD-63) which will be called the Homeland Security Presidential Directive (HSPD).The new document will "reflect changes in the bureaucracy at the Department of Homeland Security and give more importance to the ISACs (Information Sharing and Analysis Centers)."
-http://www.computerworld.com/printthis/2003/0,4814,86956,00.html
[Editor's Note (Pescatore): The original PDD-63 had much useful guidance way back in 1998. It challenged the federal government to be a model citizen in cyberspace, use existing public-private partnerships to improve information security, etc. It was largely completely ignored as cybersecurity became a hot topic. If it is rewritten without doing a "lessons learned" on why PDD-63 didn't work, this will just be an empty paper exercise. ]

FTC Temporarily Stops Pop-Up Spammer (6 November 2003)

The Federal Trade Commission (FTC) has received a temporary restraining order against two officers of D Squared Solutions, a San Diego based company that has been using Windows Messenger Service to send pop-up spam.Ironically, the pop-ups advertised pop-up blocking software. The FTC took action because it has received a large number of complaints about the company's practices.

Telecom Provider Will Block Traffic to and From Spamming Machines (4 November 2003)

Telia Sonera, a telecommunications provider that serves the Baltic and Nordic areas of northeastern Europe, plans to block all Internet traffic to and from machines that send out spam.This applies to machines infected with Trojan horse programs that have made them unwitting accomplices in spammers' schemes.Telia Sonera will not give warnings before blocking traffic, but will offer help to decontaminate the affected machines before resuming Internet traffic.
-http://www.theregister.co.uk/content/56/33763.html
[Editor's Note (Schultz): Given the high percentage of falsified sending addresses on spam, Telia Sonera's plan could prove catastrophic unless sources are verified. ]

Cyber Criminals Face Stiffer Sentences (3 November 2003)

As of November 1st, people convicted for cyber crimes face stiffer sentences, thanks to the 2002 Homeland Security Act.People who use computers to inflict bodily harm or death face sentences of 20 years to life.Another law, passed just this April, makes it harder for judges to be lenient and give sentences that are not as harsh as federal guidelines.
-http://www.denverpost.com/Stories/0,1413,36~33~1739529,00.html

Three Critical Microsoft Vulnerabilities Patched (3 November 2003)

Microsoft Corp. released the second installment of its now monthly security bulletins, patching three software holes in Windows systems that it said were "critical" security risks and a fourth problem with Microsoft Office that the company rated "important."
-http://www.computerworld.com/printthis/2003/0,4814,87058,00.html
[Editor's Note (Paller): As I read today's news stories about Microsoft's new patches, what stood out most was the lack of outrage by the reporters. Microsoft's PR people must be cheering. By moving to monthly release of new patches, they have made bad programming announcements so regular that the press is giving them a free pass. These patches fix one, or many programming errors made by Microsoft's vaunted software development team.The errors are there because that team didn't adequately check its code.Hundreds of thousands or millions of people will not install the patches, because it still takes work and expertise on the part of users.Hackers will write worms that take over those unprotected machines and use them to steal information or attack others.Some of those attacks will be low and slow so you'll never know your systems were compromised or by whom. That's the bottom line on Microsoft's patch announcements. ]

New Cyber Crime Laws Passed in Singapore (10/11 November 2003)

Newly enacted legislation in Singapore allows law enforcement with credible evidence to take pre-emptive action against suspected cyber criminals.People convicted of breaking into or defacing a web site face a jail sentences of as much as three years or fines of up to S$10,000 ($5,800).

Australian Defense Minister Enumerates Department Security Breaches (10 November 2003)

Australian Defense Minister Robert Hill said that there have been three externally launched security breaches resulting in unauthorized access to computer systems in his department during the past three years; in that same time period, there have been 13 internal attempts to breach security. These attacks plus the theft of 1,600 personal computers have raised serious concerns about security in the Australian Defense Organization.
-http://www.zdnet.com.au/printfriendly?AT=2000048600-20280750
[Editor's Note (Schultz): Figures such as these which will undoubtedly give ammunition to those who still believe the outdated 1983 FBI statistic that 80 percent of all attacks come from the inside.Mr. Hill's statistics pertain to successful, not attempted attacks.A close examination of their firewall logs would probably uncover hundreds of externally initiated attacks for every internally initiated attack. Nevertheless, the greatest risk is from internal sources; employees and contractors already have access to and knowledge about systems they attack.
(Schneier): This is useful information, but be careful of the conclusions.The story compares apples and oranges -- successful external attacks versus all internal attacks.
(Grefer) Only three successful external attacks in three years?Is it possible that there were attacks that weren't detected? ]

CSOs Concerned About DoS Attacks (7 November 2003)

A survey of 250 chief security officers (CSO) of multinational corporations found that the attacks of September 11, 2001 were more of an impetus to improve IT security than were government regulation, computer intrusions and malware attacks.Denial-of-service attacks topped the list of concerns among the respondents, closely followed by hacking and theft of corporate information.RSA and CSO conducted the survey.

[Editor's Note (Ranum): The methodology behind this survey is unclear. Reading the whitepaper it says "more than 250 readers of CSO magazine were surveyed..." which does not necessarily mean that the respondents were CSOs. ]

Wireless LAN Security (7 November 2003)

This article lists eight security risks involved in deploying wireless local area networks (LANs ) and offers suggestions for mitigating those risks.Topics addressed include rogue access points, traffic analysis and eavesdropping and insufficient policies.

Developers Catch Stealthily Planted Backdoor in Linux Kernel (6/7 November 2003)

Developers foiled a sophisticated attempt to inject a backdoor into the source code of the Linux kernel.The code could appear to be simply a programming error, but actually it would allow an attacker to gain elevated privileges on compromised systems.The anomaly was detected during a routine file integrity check.

Microsoft's Anti-virus Reward Program Gets Mixed Reviews (5/7 November 2003)

Microsoft's announcement of a $5 million fund to catch virus and worm writers has met with lukewarm reactions from some in the industry.Some experts believe the offers of bounties for information leading to the conviction of virus writers could have a chilling effect on code sharing among malware writers and could increase distrust in that community. Others believe it will have no real effect.Many would rather see Microsoft put its effort into improving Windows security.

-http://zdnet.com.com/2102-1105_2-5103261.html?tag=printthis
[Editor's Note (Schultz): I am not sure whether it will work, but I suppose it is worth a try.I'm not very convinced by critics/skeptics' concerns--the effect on code sharing among malware writers is very uncertain, and I doubt whether Microsoft's investing an extra $5 million in code development efforts would make much of a difference in the quality of its code. ]

Minnesota Legislator Won't Reveal Identity of Possible Computer Intruder (6 November 2003)

Minnesota state representative Mary Liz Holberg says she will not reveal the identity of the individual who provided her with evidence of a vulnerability in a state computer network used only by law enforcement. Officials have shut down the network known as the Multiple Jurisdictional Network Organization (MJNO) while the Bureau of Criminal Apprehension investigates whether or not there was a security breach. Holberg has been looking into the possibility that MJNO was not secure when she received a call from an individual who offered proof that the system was vulnerable; the individual accessed Holberg's MJNO files and read excerpts to her over the phone.Holberg then informed the governor's office and other state officials.

Legislator Suggests Antivirus Software be Required (6 November 2003)

During a House Energy and Commerce Committee's Subcommittee on Telecommunications and the Internet hearing, Representative Charles Bass (R-N.H.) asked, "Is there any reason why any computer in this country shouldn't have some kind of antivirus software on it as a requirement?" Others at the hearing pointed out that US citizens would perceive any such requirement to be trampling their rights.In addition, some computers, like those used in factory automation, are simply not set up to run anti-virus software.
-http://www.computerworld.com/printthis/2003/0,4814,86902,00.html
[Editor's Note (Pescatore): This is a very typical instance of how well meaning legislation aimed at technology can have disastrous results. Signature-based anti-virus barely works for its intended purpose, and it already ships on almost every PC sold. This always reminds me of when the Senate held hearings about requiring special safety seats for all children flying on commercial airline flights. At the hearing, someone pointed out that since parents would now have to buy tickets for little Susie, that more parents would be likely to drive than fly for many trips. Since driving is more dangerous per mile than flying, more children would die per year if special seats were required for children. The response from the senators: "This committee is looking at airline safety, not highway safety." Systems engineering is not a widely understood discipline.
(Schneier): While it's certainly a good idea for every computer to be outfitted with anti-virus software, I wouldn't want it legislated.I prefer liability solutions to regulation. ]

Man Allegedly Used Virus to Change Dial-Up Numbers (5 November 2003)

Italian police have charged a 39-year-old man with fraud and virus distribution for allegedly using e-mail messages that trick users into running a virus on their computers; the virus, known as Marq-A or Zelig, changes the Internet dial up number to that of a "premium rate" line. The man stood to reap more than one million Euros a month if his scheme had been allowed to run that long.
-http://www.theregister.co.uk/content/56/33801.html
[Editor's Note (Grefer): This is an oldie but a goodie.One of the original modem-hijacking scams was handled by the Federal Trade Commission in the US in 1997.The victim was tricked into downloading an executable that was a covert dialer. It even turned down the volume of the modem so victims couldn't tell their modem was dialing.See

Alleged CyberCrime Gang Members Arrested (5 November 2003)

Brazilian police arrested 18 members of a cybercrime gang; the gang members allegedly used specially crafted web sites and programs to steal passwords from people who transferred money on-line; the gang allegedly stole over $10 million last year.

E-Mail BackUp Tapes Unintentionally Thrown Out (4 November 2003)

Staff of IT contractor Telstra Enterprise Services apparently dug through trash in order to recover Australian government department and agency e-mail backup tapes that had been inadvertently thrown out. Telstra regulatory and corporate director Bill Scales said that his company told the security agencies about the security problem as soon as they discovered it.

Temporary Restraining Order Sought Against Diebold (4 November 2003)

The Electronic Frontier Foundation (EFF) and the Stanford Law School's Center for Internet and Society have filed for a temporary restraining order against electronic voting machine maker Diebold, demanding that they stop sending cease and desist letters to people and organizations that have posted internal Diebold documents of their web sites.An EFF attorney says they maintain that hosting the documents constitutes fair use under US copyright laws.

National Guard Bureau Data Sharing Suffering from Cyber Attacks (4 November 2003)

National Guard Bureau CIO Maureen Lischke said numerous cyber attacks have made it harder for her organization to share information for disaster planning and first response.Currently, the Guard installs patches manually on every PC.

[Editor's Note (Ranum): If you read the article, it will make you weep. Is this really the way that government agencies think security should be done for information sharing?]
