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.
In the past, US-CERT has received reports of phishing scams and malware campaigns related to topics that are of high-interest to the U.S. Government or news media, such as the WikiLeaks website. Users' systems have been compromised by receiving and accessing phishing emails with subject lines that seem relevant to a high-interest subject and appear to originate from a valid sender. US-CERT reminds users to remain vigilant for potential malicious cyber activity seeking to capitalize on interest in WikiLeaks. Users are advised to exercise caution in handling any email with subject line, attachments, or hyperlinks related to WikiLeaks, even if it appears to originate from a trusted source.
US-CERT encourages users and administrators to use caution when encountering these types of email messages and take the following preventative measures to protect themselves from phishing scams and malware campaigns:
VMware has released a security patch for ESX to address a vulnerability. Exploitation of this vulnerability may allow a local user to gain additional privileges on the affected system.
US-CERT encourages users and administrators to review VMware knowledgebase article 1029397 and apply any necessary updates to help mitigate the risks.
Apple has released iOS 4.2 for the iPhone, iPod Touch, and iPad to address multiple vulnerabilities. Exploitation of these vulnerabilities may allow an attacker to execute arbitrary code, initiate a call, cause a denial-of-service condition, gain system privileges, or obtain sensitive information.
US-CERT encourages users and administrators to review Apple article HT4456 and update to iOS 4.2 to mitigate the risks.
