Exploits are getting harder-and more valuableД®ven if zero-days are being seen more than ever, there is one fact that all the experts agree on: they are getting harder and more expensive to pull off.Д«etter defenses and more complicated systems mean hackers have to do more work to break into a target than they did a decade ago-attacks are costlier and require more resources. That gap is a sweet spot hackers love to hit.ДЄs a rule, however, Doerr is spot on. What started as a critical zero-day attack briefly became even worse in the period after a fix became available but before it was actually applied to users. Earlier this year, multiple hacking groups launched offensives against Microsoft Exchange email servers. The reality is a lot messier than the theory, however. In the bad situation where you see something new, that will impact one customer instead of 10,000.вЂќ Now you can learn from whatвЂ™s happening at all your customers, which helps you get smarter faster. вЂњPart of the reason youвЂ™re seeing more now is because weвЂ™re finding more,вЂќ says MicrosoftвЂ™s Doerr. Where old tools, such as antivirus software, meant fewer eyeballs on strange activity, today a large company can catch a small anomaly across millions of machines and then trace it back to the zero-day that was used to get in.

Groups like GoogleвЂ™s Threat Analysis Group (TAG), KasperskyвЂ™s Global Research & Analysis Team (GReAT), and MicrosoftвЂ™s Threat Intelligence Center (MSTIC) have an enormous troves of talent, resources, and data-so much, in fact, that they rival an intelligence agencyвЂ™s capabilities to detect and track adversary hackers.Д¬ompanies like Microsoft and CrowdStrike are among those that run detection efforts on a massive scale. вЂњI think this denotes an escalation in the ability to detect more sophisticated attacks,вЂќ he says. But there are also better tools.Дefenders have clearly gone from being able to catch only relatively simple attacks to detecting more complex hacks, says Mark Dowd, founder of Azimuth Security. One change the trend may reflect is that thereвЂ™s more money available for defense, not least from larger bug bounties and rewards put forward by tech companies for the discovery of new zero-day vulnerabilities. You can look at the data, such as GoogleвЂ™s zero-day spreadsheet, which tracks nearly a decade of significant hacks that were caught in the wild. That suggests defenders are becoming better at catching hackers in the act.

No one we spoke to believes that the total number of zero-day attacks more than doubled in such a short period of time-just the number that have been caught. In fact, some experts say it might be mostly good news. While there may be an increasing number of people developing or buying zero-days, the record number reported isnвЂ™t necessarily a bad thing. So theyвЂ™re playing a significant role in this increase which I donвЂ™t think many people are giving credit for.вЂќ Cyberdefenders have a better spotlight вЂњOne-third of the zero-days weвЂ™ve tracked recently can be traced directly back to financially motivated actors. вЂњFinancially motivated actors are more sophisticated than ever,вЂќ Semrau says.

And cybercriminals, too, have used zero-day attacks to make money in recent years, finding flaws in software that allow them to run valuable ransomware schemes.
