Vulnerabilities and exploits

This month’s patch Tuesday fixes a small set of critical vulnerabilities in a variety of client side software and one “important” server side Forefront UAG data leakage/information disclosure issue. Six bulletins have been created to address eleven exploitable flaws.

According to data collected by Kaspersky Lab, almost 700,000 infected users have been counted at the beginning of April and the number could be higher. Although Mac OS X can be a very secure operating systems, there are certain steps which you can take to avoid becoming a victim to this growing number of attacks. Here’s our recommendation on 10 simple tips to boost the security of your Mac.

On 20 March, we detected a spam campaign targeting passengers of US Airways. After clicking the link from an email a series of redirects eventually leads to a domain hosting BlackHole Exploit Kit.

The twitter infosec sphere last night and the blogosphere this morning is in a bit of a frenzy about the public leak of a DoS PoC targeting CVE-2012-0002, the RDP pre-auth remote. First off, patch now. Now. If you can’t, use the mitigation tool that Microsoft is offering – the tradeoff between requiring network authentication and the fairly high risk of RCE in the next couple of weeks is worth it. You can see the list of related links on the side of this page, one was included for MS12-020.

Last week researchers found vulnerabilities in the Google Wallet payment system. The vulnerability was leveraged to display the current PIN number but required root access to the device. The very next day a new vulnerability was discovered in how application data is handled in the Wallet app requiring no root access. I expect these to be just the beginning of a scavenger hunt for Google Wallet vulnerabilities in the future.

Many of the apps we enjoy are free. Well, to call them free is a bit misleading. You pay for the apps by looking at advertisements.
