0-Day Market Hits USD $20 million. Another heavyweight (@advance_sec0) has entered the 0-day broker market, and they’re buying everything. Full exploit chains across the board. OS, mobile, browsers, servers, MS office, mail, databases, network gear, messengers, web apps - you name it. Mobile clearly leads the pack: up to $20M for an SMS/MMS full chain, which is about a 400 to 500% jump in just five years. Sure, part of it is because exploits are getting rarer and harder to develop. But the other driver is pure market heat: brokers are now outbidding each other to lock down supply. Smart business. Dangerous game.
