Along with French vulnerability research firm VUPEN, ReVuln is among a few companies that openly sell vulnerability information to government agencies and other private customers and refuse to report the vulnerabilities their researchers find to the affected vendors so they can be fixed.
"The vulnerabilities included in our Zero-day feed [a subscription-based service] remain undisclosed by ReVuln unless either the vulnerability is discovered and reported by a third party or the vendor publicly or privately patches the issue," the company states on its website.
It's a somewhat controversial business model that has been criticized by digital rights advocates and various people from the IT security industry who argue that it makes the Internet less safe because the vulnerabilities remain unpatched and known to third parties who may be interested in exploiting them for offensive purposes.
However, the practice is not new. It's been known for years in the security research community that some companies and independent researchers are selling information about unpatched vulnerabilities to governments and other private buyers, but such transactions used to be done discreetly.
In the absence of additional details and vendor confirmation, it's hard to independently confirm the existence of these vulnerabilities. However, Auriemma's reputation as a prolific vulnerability researcher and his past work in the field of SCADA security lends credibility to his company's claims.
During the past few years, before creating ReVuln together with former RIM security researcher Donato Ferrante, Auriemma reported dozens of vulnerabilities in SCADA software.
"Luigi [Auriemma] has found many vulnerabilities in SCADA and ICS [industrial control systems] in the past, and I'm sure he will continue to in the future," said Dale Peterson, CEO of Digital Bond, a Sunrise, Florida-based company that specializes in ICS security research and assessment, Tuesday via email. "He is talented."
That said, finding vulnerabilities in SCADA software is not that hard to do, Peterson said. "The issue with these applications is they were developed without security integrated into the development process."
"It is similar to what Microsoft was doing in the 90s," he said. "Without a security development lifecycle you will see the common programming mistakes that lead to vulnerabilities and exploits over and over."
As far as ReVuln's business model is concerned, "Digital Bond's position is that the person who finds the vulnerability can decide what to do with it," Peterson said. "Report to the vendor, a CERT, sell it, publish it, or keep it for future use. We have done all of the above and make our decision on a case by case basis."
