![]() ![]() Jointly, half a dozen boutique exploit providers have the capacity to offer more than 100 exploits per year." A determined attacker (for example, 25 zero-days per year for USD $2.5 million) this has broken the monopoly that nation states historically have held regarding ownership of the latest cyber weapon technology. Specialized companies are offering zero-day vulnerabilities for subscription fees that are well within the budget of. These numbers are considered a minimum estimate of the 'known unknowns', as it is unlikely that cyber criminals, brokers, or government agencies will ever share data about their operations. Further, it has been found that these vulnerabilities remain private for an average of 151 days. "NSS Labs has analyzed ten years of data from two major vulnerability purchase programs, and the results reveal that on any given day over the past three years, privileged groups have had access to at least 58 vulnerabilities targeting Microsoft, Apple, Oracle, or Adobe. Then this knowledge is offered in black marketplaces to the highest bidder, no matter if it is a private company that will use it against a competitor or a government that wants to use it to target the critical infrastructure of an adversary.Ī study conducted by the experts at NSS Labs in 2013 titled " The Known Unknowns" reported that every day during a period of observation lasting three years, high-paying buyers had access to at least 60 vulnerabilities targeting common software produced by Adobe, Apple, Microsoft and Oracle. Zero-day hunters are independent hackers or security firms that analyze every kind of software searching for a vulnerability. It has been estimated that every year, zero-day hunters develop a combined 100 exploits, resulting in 85 privately known exploits, and this estimation does not include the data related to independent groups of hackers, whose activities are little known. In 2013 it was estimated that the market was able to provide 85 exploits per day, a concerning number for the security industry, and the situation today could be worse. Governments aren't the only buyers however, exploit kits including zero-day are also acquired by non-government actors. ![]() Governments are the primary buyers in the growing zero-day market. Zero-day exploits are commodities in the underground economy. ![]() Java platform, Adobe software).Ī few days ago, for example, security experts at FireEye detected a new highly targeted attack run by the APT28 hacking crew exploiting two zero-day flaws to compromise an "international government entity." In this case, the APT28 took advantage of zero-day vulnerabilities in Adobe Flash software (CVE-2015-3043) and a Windows operating system (CVE-2015-1701). In some cases, security experts have discovered large scale operations infecting thousands of machines by exploiting zero-day vulnerabilities in common applications (e.g. mobile OSs for surveillance, SCADA application within a critical infrastructure). Zero-day exploits could be used by threat actors for sabotage or for cyber espionage purposes, or they could be used to hit a specific category of software (i.e. Zero-day exploits are among the most important components of any cyber weapons, and for this reason they are always present in the cyber arsenals of governments. Security experts have debated on several occasions the importance of the zero-day exploitation to design dangerous software that could target any kind of application. The majority of state-sponsored attacks that go undetected for years rely on the exploitation of an unknown flaw in popular products on the market and SCADA systems. The availability of zero-day exploits is a key element for a successful attack. ![]()
