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.

Japan Earthquake and Tsunami Disaster Email Scams, Fake Antivirus and Phishing Attack Warning

US-CERT would like to warn users of potential email scams, fake antivirus and phishing attacks regarding the Japan earthquake and the tsunami disasters. Email scams may contain links or attachments which may direct users to phishing or malware-laden websites. Fake antivirus attacks may come in the form of pop-ups which flash security warnings and ask the user for credit card information. Phishing emails and websites requesting donations for bogus for charitable organizations commonly appear after these types of natural disasters.

US-CERT encourages users to take the following measures to protect themselves:

Apple Releases Safari 5.0.4

Apple has released Safari 5.0.4 to address multiple vulnerabilities in the ImageIO, libxml, and WebKit packages. These vulnerabilities may allow an attacker to execute arbitrary code, cause a denial-of-service condition, obtain sensitive information, or conduct cross-site scripting attacks.

US-CERT encourages users and administrators to review Apple article HT4566 and apply any necessary updates to help mitigate the risks.

Apple Releases iOS 4.3

Apple has released iOS 4.3 for the iPhone 3 GS and later, iPod touch (3rd generation) and later, and iPad to address multiple vulnerabilities.
