The Web exploded in outrage as the House Judiciary Committee conducted hearings on Nov. 16 to discuss the Stop Online Piracy Act. Consumer advocacy groups, industry organizations and technology giants slammed Congress for stacking the witness panel with five advocates for the bill and only one against the bill.

None of the speakers supporting the bill had any security expertise, leaving them unable to respond to charges that the filtering provisions in SOPA would cause problems for the DNSSEC security technology that is increasingly being adopted to prevent abuses of the Domain Name Service system.

In a different hearing a day earlier, the Department of Justice asked the House Judiciary Committee's Subcommittee on Crime, Terrorism and Homeland Security to expand the Computer Fraud and Abuse Act to make it a crime to violate terms of service on Websites. The amendment would make it a federal crime for users to use pseudonyms online.

Earlier in the week, Facebook users logged in and were appalled to find their newsfeeds were full of explicit content and violent images. It turned out that a massive spam attack had taken advantage of an injection flaw in Web browsers. Users were tricked into copying and pasting malicious code into the URL bar of the Web browser and executing the code, which hijacked the newsfeed to spread violent and explicit images.

Facebook declined to identify which Web browser had the flaw but said the problem was under control. The social networking giant also said the perpetrators had been identified and it was pursuing legal action against them.

The technique used in the spam attack was "not new," according to Mike Geide, senior security researcher at Zscaler ThreatLabZ. There have been several scams that relied on the "self-inflicted Javascript injection method," he said.

"Be careful of all actions you take while online, even copying and pasting content into your URL bar," Geide warned.

Security researchers disclosed that they found that some versions of the DNSchanger malware had been distributed by the sophisticated TDSS rootkit. The DNSchanger malware was usually part of a "cocktail" of other malicious applications running on infected machines, according to Kaspersky Lab researchers.

Kaspersky Lab also uncovered more details about the Duqu Trojan, reporting that a research team had identified all the individual components of the malware and managed to track down the initial email message that launched an attack against an unnamed company in Sudan. Kaspersky researchers were also "convinced" that despite other security researchers' claims to the contrary, whoever wrote the malware was involved in some way in the development of Stuxnet worm.

The ongoing research into Duqu, and the fact that it may be targeting companies that make industrial control systems in order to steal information, was underscored by reports that attackers had compromised a vendor that makes supervisory control and data acquisition (SCADA) software and stole customer credentials.

At least one set of credentials were allegedly used early in November to remotely break into a public water utility's networks in Illinois and damage a water pump. A Norwegian government agency also reported there were attacks this year against at least 10 oil, energy and defense companies in which sensitive information was stolen and transferred out of the country.

The ongoing investigation of last year's Directors Desk breach at Nasdaq stock exchange has uncovered lax security practices, such as outdated software and improperly patched systems. The issues were a surprise considering the sensitivity of financial systems, Reuters said.
