The US-CERT Current Activity web page is a regularly updated summary of the most frequent, high-impact types of security incidents currently being reported to the US-CERT.
Apple has released a security advisory related to the recent Mac fake anti-virus software. The most common names for this fake anti-virus software are MacDefender, MacProtector, and MacSecurity. This fake anti-virus software is the result of a phishing scam targeting Mac users that redirects them from legitimate websites to fake websites. These fake websites notify the user that their computer is infected with a virus, and the user is tricked into installing the fake anti-virus software to solve the issue. The ultimate goal of the fake anti-virus software is to steal the user's credit card information.
US-CERT encourages users to perform the following preventative measures to help mitigate the risks:
Google has released Chrome 11.0.696.71 for Windows, Mac, Linux, and Chrome Frame to address multiple vulnerabilities. These vulnerabilities may allow an attacker to execute arbitrary code.
US-CERT encourages users and administrators to review the Google Chrome Releases blog entry and update to Chrome 11.0.696.71 to help mitigate the security risks.
Microsoft has released a new, fully supported version of the Enhanced Mitigation Experience Toolkit (EMET) designed to mitigate exploitation attempts. EMET allows users to manage security mitigation technologies to make it more difficult for an attacker to exploit software vulnerabilities.
US-CERT encourages users and administrators to review the Microsoft Security Research and Defense blog entry for further information about this new version of EMET.
