That last can really be a problem, since older versions of Java are still susceptible to security exploits from malware.
FORBES: Browsium Allows Your IT Dept To Finally Upgrade From IE6
Ozancin wagged his finger at the sendmail mail transfer agent (MTA) as the cause of many past security exploits, including but not limited to buffer overflows.
But the largest collections currently available from Core Security Technologies, Immunity and an open source project known as Metasploit include exploits for less than 10% of the 14, 000 security flaws publicly revealed in information technology systems over the last five years.
Only 76% of those exploits were caught by the security software on average.
FORBES: Study Shows Programs Designed To Catch Hackers' Exploits Miss Nearly Half
Vupen is just one of a number of companies that have created controversy in the security community by profiting from zero-day exploits rather than working with software firms to fix the hackable vulnerabilities they use.
FORBES: Government-Funded Hackers Say They've Already Defeated Windows 8's New Security Measures
Google hacking was first popularized by Johnny Long, a penetration tester who created a Google Hacking Database that allowed anyone to add interesting security search queries that might turn up vulnerabilities to exploits like SQL Injection or Cross-Site Scripting.
FORBES: Researchers Will Turn Google And Bing Into Web Bug Warning System
In the year to come, security professionals are warning of bank code-stealing exploits that are much slicker and more convincing--hidden in guises as harmless as a banner ad on a reputable Web site or a message from a friend on a social network.
In the months after he started the company, Schlein, who is now chairman of Fortify's board, scoured the tech world for security sages to help him amass a reference shelf of malicious exploits.
Many of these exploits are posted by users who are generally concerned with security and demonstrate the exploit to help the company fix it.
FORBES: Artificial Intelligence Will Defeat CAPTCHA -- How Will We Prove We're Human Then?
According to Crosby, traditional security solutions rely on detection and hence fail to block targeted attacks which often use zero day exploits.
Intrusion detection, capable of spotting zero day exploits, must be deployed to audit and test the recognition and response capabilities of your corporate security defences.
And there is a silver lining: modern cryptography exploits the fact that some things (such as factoring large numbers) are difficult in order to provide security.
