New Phishing Hits Domain Owners Accounts At eNom , NetworkSolutions

Sophos have reported a new kind of phishing campaign. Instead of the regular bank phish , or the more recent university/ webmail email account phish , this new campaign targets domain registrar accounts. The email fakes the From address (purports to come from tech@enom.com) and ask the user to update their account due to some maintenance, in a manner similar to bank phishes . The following two subject lines were seen in the phish emails, some with additional words such as “attention”, “warning”, or “ IncidentID : #####”. Clicking on the link will take the user to a link in the url format of www.enom.com.someotherdomain .

Hackers penetrate South Korean missile manufacturer
[Source: http://www.theregister.co.uk] - 01 October 2008

Black hat hackers were able to steal information from a South Korean missile manufacturer after planting malicious code on the company's computer system, according to news reports.

According to the country's National Security Research Institute, the code was installed on the computer network of LIGNex1 Hyundai Heavy Industries, a manufacturer of guided missiles, ground-to-air weapons, war ships, and submarines.

"The research institute suspects the culprits are Chinese or North Korean hackers but doesn't know specifically what information they stole," an official said. "In the worst case, the blueprints of missiles and Aegis ship could have been stolen."

TCP flaws allow deadly DoS attacks, finders say
[Source: http://www.securityfocus.com] 02 October 2008

Two security researchers claimed that flaws in the network stacks used by most operating systems could allow attackers to send a low-bandwidth denial-of-service attack that could leave victims' systems unresponsive.

The researchers -- Jack Louis and Robert E. Lee, both of vulnerability assessment firm Outpost24 -- discovered the flaws while creating a scalable network scanner to test large numbers of Internet addresses. Some of the servers scanned by the tool became non-responsive, and after further investigation, the duo discovered a class of issues in the network stacks used by most operating systems. In the more "interesting" cases, the target machines fail to recover after the attack ceases, Lee, the chief security officer for Swedish company, told SecurityFocus .

Trojan attacks Microsoft's emergency patch vuln

[Source: http://www.theregister.co.uk] 24 October 2008

A day after Microsoft released an emergency patch for a critical flaw that could allow self-replicating attacks, researchers have identified a nasty trojan that attempts to exploit the vulnerability.

Variants of the data-stealing trojan known by names including Gimmiv.A and Spy-Agent.da have morphed over the past few weeks to exploit a major weakness in virtually all versions of the Windows operating system. If successful, the exploit could transform the malware into a virulent worm that allows a single infected machine to contaminate any other vulnerable machine over a local network without requiring any interaction on the part of the end users.

Phishing e-mail says it's from FBI
[Source: http://www.virusbuster.hu] 24 October 2008

Do not open unsolicited e-mails!

A spam e-mail claiming to be from FBI Deputy Director John S. Pistole is currently being circulated. This attempt to defraud is the typical e-mail scam using the name and reputation of an FBI official to create an air of authenticity.

As with many scams, the e-mail advises the recipient that they are the beneficiary of a large sum of money which they will be permitted to access once fees are paid and personal banking information is provided. The appearance of the e-mail leads the reader to believe that it is from FBI Deputy Director John S. Pistole. The scam e-mails give the appearance of legitimacy through the use of pictures of FBI officials, seal, letter head, and/or banners.

Survey: 88% of Mumbai's wireless networks easy to compromise

[Source: http://blogs.zdnet.com] 16 October 2008

Deloitte's recently released Wireless Security Survey assessing Mumbai's — India's financial capital — state of security awareness in respect to wireless security, shows an ugly picture of insecure wireless networks in both, business, and residential districts. With Mumbai being the home of India's most important financial institutions, next to the majority of multinational corporations, it may also turn into the playground for the next high profile data breach.

The key findings of the survey are:

  • Of the 6729 wireless networks seen, 36% appeared to be unprotected i.e. without any encryption
  • 52% were using low level of protection i.e. Wired Equivalent Privacy (WEP) encryption
  • Over 95% of the networks broadcast their SSID, with 25% of these using their router's default SSID
  • Balance 12% were using the more secure Wi-Fi Protected Access (WPA)

Researchers find keyboards to be tattletales
[Source: http://www.securityfocus.com] - 20 October 2008

Two researchers at the Swiss Federal Institute of Technology (EPFL) in Lausanne, Switzerland have surveyed 11 different wired computer keyboards and found that all leaked keystroke information.

The researchers, Martin Vuagnoux and Sylvain Pasini, used four different attacks to gather information at a distance of up to 20 meters via the electrical signals emitted from the they keyboards. The antenna used by the researchers could read the data even through walls, Vuagnoux said.

"We conclude that wired computer keyboards sold in the stores generate compromising emanations -- mainly because of the cost pressures in the design," Vuagnous wrote on a Web page describing the attacks. "Hence they are not safe to transmit sensitive information. No doubt that our attacks can be significantly improved, since we used relatively unexpensive equipments (sic)."

Anonymous domain registration nixed amid fraud complaints
[Source:http://www. theregister.co.uk] – 2- October 2008-11-12

A company that provides a controversial service to domain name registrars says it is severing ties with Estdomains amid complaints that the Eastern European company makes it too easy to register sites that are used by spammers and scammers.

Directi, through a subsidiary called LogicBoxes, had been providing an array of products and services to Estdomains, including one known as PrivacyProtect, which shields the identity of domain-name owners. Critics have long claimed it is used by operators of sites that engage in spam, malware and other illegal acts.

About a month ago, Directi amended its relationship with Estdomains and stopped providing the Estonian registrar with the PrivacyProtect service, company officials said. While PrivacyProtect is used by many registrars, they say most of the abuse came from customers registering sites through Estdomains. That, in turn, prompted Directi to terminate its agreement in hopes that anti-fraud proponents would stop targeting the service.

ICANN cast as online scam enabler
[Source: http://www. theregister.co.uk ] – 3 October 2008

Two recently issued reports portray the Internet Corporation for Assigned Names and Numbers (ICANN) as a bureaucracy that enables cyber criminals.

In one report (PDF) , researchers Jart Armin, James McQuaid and Matt Jonkman detail how one of ICANN's prized sponsors has ties to one of the net's more prolific sources of malware and illegal online pharmacies. It's called LogicBoxes, and over the past two years, ICANN has listed it as a sponsor for meetings that took place in Los Angeles and Delhi, India.

It turns out that LogicBoxes has an association with Atrivo, a network provider that also goes by the name of Intercage. According to the study, a random sampling of 2,600 addresses hosted by Atrivo revealed 7,340 malicious web links, 910 infected websites, 310 malicious binaries, and 113 botnet command and control servers. As an autonomous systems (AS) provider, the Concord, California-based company controls a large number of IP addresses.

Secure Coding

Easily avoided software defects are a primary cause of commonly exploited software vulnerabilities. The CERT /CC has observed, through an analysis of thousands of vulnerability reports, that most vulnerabilities stem from a relatively small number of common programming errors. By identifying insecure coding practices and developing secure alternatives, software developers can take practical steps to reduce or eliminate vulnerabilities before deployment.

The CERT Secure Coding Initiative works with software developers and software development organizations to reduce vulnerabilities resulting from coding errors before they are deployed. We work to identify common programming errors that lead to software vulnerabilities, establish standard secure coding standards, educate software developers, and to advance the state of the practice in secure coding.
