A security company is offering $20,000 (£10,200) for information on undisclosed security flaws in Windows.
Digital Armaments, which doesn't list a phone number or a headquarters address on its website, is offering the money as part of the "Hacker's Challenge." The company is also soliciting for flaws in what they term "Windows Diffuse Applications."
Submitters need to illustrate a working exploit and document it, according to the Digital Armaments website, which is filled with misspelled words.
There's nothing illegal about paying security researchers for flaws, but it does tend to annoy software companies whose products are affected.
WabiSabiLabi, based in Switzerland, took the idea of compensating researchers a step further last year by opening a site for them to sell vulnerabilities in auctions. In response to criticism, company officials countered that researchers could sell zero-day vulnerabilities on the black market.
Microsoft, whose security vulnerabilities are generally high profile, advocates that researchers discreetly alert it to software problems so users aren't put at risk. Companies generally refuse to pay for software vulnerabilities.
Digital Armaments says on its website its research team was founded in 2003, and offices were opened in the US later that year.
Efforts to reach Digital Armaments were unsuccessful.
