Hearing to Determine if ACS:Law is Liable for Wasted Legal Costs (April 18, 2011)

A judge in the UK has ruled that ACS:Law and its sole solicitor, Andrew Crossley, may be responsible for wasted costs in the case involving speculative invoicing of alleged illegal file-sharers. The company sent out thousands of letters, threatening people with legal action if they did not pay GBP 500 (US $813) to settle allegations of illegal file-sharing. The court had originally been asked to hear the cases brought by ACS:Law, but shortly before they came to trial, the firm sought to have them dismissed. The judge did not grant that request. A hearing has been set for June to determine if ACS:Law and Crossley are liable for wasted legal costs.

Coreflood Takedown Tactics Questioned (April 15, 2011)

Although people were happy to see the Coreflood botnet go, some have expressed concern about the tactics used in its recent takedown. Federal prosecutors obtained a temporary restraining order allowing them to replace several identified Coreflood command-and-control (C&C) servers with their own servers, which were then used to send stop commands to machines that were infected with Coreflood malware. Electronic Frontier Foundation technology director Chris Palmer said the method "is not a safe way to go about
[disabling malware ]
and it's divergent with standard practice." Previously, botnets have been taken down by taking down the C&C servers, which renders the botnets silent for a while until new C&C servers are established. Others are less concerned about the impact of this specific takedown than they are about the precedent it sets. Still others say the technique was not intrusive because it just told the malware to stop running.

[Editor's Note (Schultz and Paller): Whether or not we like it, the worsening nature of cybercrime is increasingly dictating that law enforcement take more austere and severe measures. ]

US Judge Trying to Determine if Google Breached Wiretap Law (April 18, 2011)

A federal judge presiding over combined lawsuits against Google over its inadvertent collection of packets sent over unprotected wireless networks is trying to decide if Google breached the Wiretap Act. US District Judge James Ware is seeking a definition of "radio communication" under the Wiretap Act to determine whether or not home Wi-Fi networks fall under this purview. Google says they do, while the plaintiffs' legal team says that the data were only sent over radio waves while traveling between a home router and a laptop. Both parties agree that eavesdropping on cordless phones is illegal.

Which Cyber Security Specialists are Most Needed? (April 18, 2011)

While no one would dispute that cyber security specialists in government are in short supply, there is disagreement about which areas of cyber security are the most necessary and therefore merit higher pay. The US needs between 20,000 and 30,000 cyber security specialists to effectively protect cyberspace. Competitions (like the US Cyber Challenge initiative's Cyber Quests - see below) aim to draw those with raw talent into the field of cyber security and provide them with specialized technical training. Some say that those who specialize in network operations and penetration testing are the greatest need. Others maintain the need is higher for information assurance analysts, auditors and administrators. The second group currently has higher average salaries than the first group, but the balance may shift as auditors and administrators are increasingly seeing their work automated.
Cyber Quests:

Adobe Patches Flash Reader Vulnerability (April 15 & 16, 2011)

Adobe has released a fix for a zero-day vulnerability in Flash Player that was disclosed last week. The flaw is being actively exploited in targeted attacks with maliciously-crafted Excel and Microsoft Word documents. The updated version of Flash Player for Windows, Mac OS X, Linux and Solaris is A fix for Flash Player on Android smartphones is expected by the end of the month. The flaw has already been fixed in Google's Chrome browser.


[Editor's Note (Honan): As many Adobe applications are usable across many different platforms they are a very attractive target to cyber criminals. Adobe really need to do a root and branch analysis of their applications and implement better security within them. ]

Two-Year Prison Sentence for DDoS Attacks (April 15, 2011)

Bruce Raisley has been sentenced to two years in prison for launching a series of distributed denial-of-service (DDoS) attacks against nine websites. Rollingstone.com and other sites published accounts of an online affair Raisley had with a fictitious woman. Raisley had been part of a vigilante Internet group that posed as children online to trap sexual predators in sting operations. Raisley had a falling out with the group's leader, who then proceeded to fabricate an online identity for the fictitious woman with whom Raisley engaged in the online affair. Raisley was also ordered to pay more than US $90,000 in restitution.

[Editor's Comment (Northcutt): I would not have thought you could have an affair with a fictitious woman, but I read the other day about cloud girlfriends, so I suppose it is possible, call me silly, but I think I prefer holding hands and long walks along the beach:

Private Industry Wants Better Cyber Threat Information Sharing with Government (April 15, 2011)

In testimony before the US House Committee on Homeland Security, representatives from private sector companies such as AT&T, the North American Electric Reliability Corporation, and the Financial Services Sector Coordinating Council said they need the government to be more forthcoming with information about cyber security and cyber threats. Timely information sharing and collaboration between agencies and private sector companies that own and operate elements of the country's critical infrastructure is critical to protecting vulnerable systems. The companies want to share information with DHS, too. They say there should be a standard protocol to streamline the alert and information sharing processes.
[Editor's Note (Honan): There is a European project currently looking into the setting up of trusted networks to facilitate information sharing amongst groups of stakeholders. Have a look at the NEISAS website www.neisas.eu, which is an EU funded project, for more information. ]

Updates for Mac OS X and Safari (April 15, 2011)

On Thursday, April 14, Apple released updates for Mac OS X, Safari and several other products, including the iPhone and iPad. The update for Mac OS X (Security Update 2011-002) affects versions 10.5 and 10.6 of the operating system and addresses issues related to digital certificates attackers were able to obtain fraudulently. The certificates were added to a blacklist so they will be recognized as untrustworthy. The updated version of Safari (5.0.5) addresses a pair of vulnerabilities that could be exploited to cause unexpected application termination or arbitrary code execution.

Guilty Plea in Stolen Credit Card Data Case (April 13, 14 & 15, 2011)

A Malaysian man has pleaded guilty to access device fraud and has admitted that he broke into a US Federal Reserve Bank computer network and installed malware. Prosecutors say Lin Mun Poo made a living by breaking into networks at financial institutions and other organizations, and selling data he stole from those networks. Lin was arrested last October in New York after law enforcement agents observed a transaction in which Lin sold credit card information for US $1,000. His "heavily encrypted" laptop was seized, but agents were apparently able to break the encryption.
[Editor's Comment (Northcutt): This article has additional information, most of the news sites are rehashing each other:

Oracle to Fix 73 Vulnerabilities in Quarterly Update (April 14, 15 & 18, 2011)
