What You Need to Know About the Java Exploit

January 12, 2013

On Thursday, the world learned that attackers were breaking into computers using a previously undocumented security hole in Java, a program that is installed on hundreds of millions of computers worldwide. This post aims to answer some of the most frequently asked questions about the vulnerability, and to outline simple steps that users can take to protect themselves.

Adobe, Microsoft Ship Critical Security Updates

January 8, 2013

Adobe and Microsoft today separately issued updates to fix critical security vulnerabilities in their products. Adobe pushed out fixes for security issues in Acrobat, Adobe Reader and its Flash Player plugin. Microsoft released seven patches addressing at least a dozen security holes in Windows and other software, although it failed to issue an official patch for a dangerous flaw in its Internet Explorer Web browser that attackers are now actively exploiting.

Internet Explorer Users: Please Read This

September 18, 2012

Microsoft is urging Windows users who browse the Web with Internet Explorer to use a free tool called EMET to block attacks against a newly-discovered and unpatched critical security hole in IE versions 7, 8 and 9. But some experts say that advice falls short, and that users can better protect themselves by using an alternative browser until Microsoft can issue a proper patch.

Researchers: Java Zero-Day Leveraged Two Flaws

August 29, 2012

New analysis of a zero-day Java exploit that surfaced last week indicates that it takes advantage of not one but two previously unknown vulnerabilities in the widely-used software. The latest figures suggest that more than a billion users may be vulnerable to attack.

New Java Exploit to Debut in BlackHole Exploit Kits

July 5, 2012

Malicious computer code that leverages a newly-patched security flaw in Oracle’s Java software is set to be deployed later this week to cybercriminal operations powered by the BlackHole exploit pack. The addition of a new weapon to this malware arsenal will almost certainly lead to a spike in compromised PCs, as more than 3 billion devices run Java and many of these installations are months out of date.

Blocking JavaScript in the Browser

May 25, 2011

Most Web sites use JavaScript, a powerful scripting language that helps make sites interactive. Unfortunately, a huge percentage of Web-based attacks use JavaScript tricks to foist malicious software and exploits onto site visitors. To protect yourself, it is critically important to have an easy method of selecting which sites should be allowed to run JavaScript in the browser.

It is true that selectively allowing JavaScript on known, “safe” sites won’t block all malicious scripting attacks: Even legitimate sites sometimes end up running malicious code when scammers figure out ways to sneak tainted, bogus ads into the major online ad networks. But disallowing JavaScript by default and selectively enabling it for specific sites remains a much safer option than letting all sites run JavaScript unrestricted all the time.
