Aurora Attack — Resistance Is Futile, Pretty Much
eldavojohn writes "Do you have branch offices in China? iSec has published a new report (PDF) outlining the severity of the attacks on Google.cn, allegedly by the Chinese government, dubbed 'Aurora' attacks. Up to 100 companies were victims, and some are speculating that resistance to such attacks is futile. The report lays out the shape of the attacks — which were customized per-company based on installed vulnerable software and antivirus protection: '1. The attacker socially engineers a victim, often in an overseas office, to visit a malicious website. 2. This website uses a browser vulnerability to load custom malware on the initial victim's machine. 3. The malware calls out to a control server, likely identified by a dynamic DNS address. 4. The attacker escalates his privilege on the corporate Windows network, using cached or local administrator credentials. 5. The attacker attempts to access an Active Directory server to obtain the password database, which can be cracked onsite or offsite. 6. The attacker uses cracked credentials to obtain VPN access, or creates a fake user in the VPN access server. 7. At this point, the attack varies based upon the victim. The attacker may steal administrator credentials to access production systems, obtain source code from a source repository, access data hosted at the victim, or explore Intranet sites for valuable intellectual property.' The report also has pages of recommendations as well as lessons learned, which any systems administrator — even those inside the US — should read and take note of." -
Entropy Problems For Linux In the Cloud
CalTrumpet writes "Our research group recently spoke at Black Hat USA on the topic of cloud computing security. One of the interesting outcomes of our research was the discovery that the combination of virtualization technologies and public system images results in a problem for random number generation on guest operating systems. This is especially true for Linux, since its PRNG uses only a small set of entropy-gathering events, and virtual Linux images often generate SSH host keys within seconds of their initial boot. The slides are available; the PRNG vulnerability material begins at slide 63." -
Browser Privacy Test
lazyforker writes "A NYTimes blog post reports the results of security researcher Kate McKinley's tests of various browsers' (FireFox, Chrome, IE, Safari) privacy protection mechanisms. Specifically she tested their cookie handling. She also examined their handling of Flash's cookies. In summary: Safari on Mac OS X (in the 'private browsing' mode) is not so private ('quirky'). Safari on XP is not private at all. Flash behaves awfully everywhere." -
EFF and Sony Disclose New DRM Security Hole
Dotnaught writes "The Electronic Frontier Foundation (EFF) and SONY BMG Music Entertainment said on Tuesday that SunnComm is offering a patch to fix a security vulnerability with its MediaMax Version 5 content protection software on 27 SONY BMG CDs. Security firm iSEC Partners discovered the hole following a request by the EFF to examine the SunnComm software. The vulnerability involves a directory installed on users' computers by the MediaMax software that could allow a third party to gain control over the affected Windows PC. The EFF and iSEC delayed disclosing the problem until SunnComm could develop a fix."
