Exploit:W32/CVE-2010-0188.B identifies malicious PDF files downloaded by the Blackhole exploit kit that exploit a known vulnerability.
Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.
The malicious PDF files target a known vulnerability in Adobe Reader; to prevent successful exploitation, please ensure you install the latest updates available for Reader and/or remove any old, unnecessary installations.
To ensure you have the latest version of Reader, please refer to the vendor's product page.
A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:
Check for the latest database updates
First check if your F-Secure security program is using the latest detection database updates, then try scanning the file again.
Submit a sample
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it to F-Secure Labs for re-analysis.
NOTE If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.
Exclude a file from further scanning
If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.
Note You need administrative rights to change the settings.
The exploit file is delivered by the highly-prevalent Blackhole exploit kit, a utility program used by attackers to silently install their malware onto a user's computer during a drive-by download attack.
The exploit kit is typically hosted on a short-lived webpage, and victims are driven to these pages by either hijacking traffic from a legitimate, compromised website, by redirecting traffic from search engines using Search Engine Optimization (SEO) poisoning, or through malicious links in spam emails.
Once a visitor is on the malicious page, the exploit kit silently probes the visitor's computer system for vulnerabilities in specific applications (in some cases, specific versions of these applications). Targeted applications include Java Runtime Environment, Media Player, Adobe Flash Player and Adobe Reader, and specific Windows components.
If found, the kit automatically exploits the vulnerabilities and downloads additional files (the kit's payload) onto the victim machine. The files downloaded by Blackhole onto the victim machine are usually other known malware, including:
