Firms detect breaches sooner, but attackers have gotten nastier

Firms are detecting breaches sooner, according to a new report from Mandiant

Firms are detecting breaches nearly 30 percent sooner than before, according to a new report from Mandiant, but attackers are also getting more aggressive in their methods by demanding millions for not releasing data, or erasing all systems around them as they go.

Last year, it took an average of 146 days for a company to discover a breach, down from 205 in 2014 — and 416 in 2011.

This is based on enterprise customers who turn to Mandiant, a FireEye company, to investigate breaches after they have occurred.

"Certainly if an organization detects a breach on their own, and they shut it down in a matter of days, it would not be reported in our statistics," said Charles Carmakal, a vice president with Mandiant Consulting.

The company also offers FireEye-as-a-service, which continuously monitors client networks, but those response rates are tracked separately, he said.

There are two main reasons that attacks are getting detected sooner, he said. One is that organizations are getting better at spotting them.

However, despite better security, few organizations are successfully able to keep out determined attackers.

In almost every test conducted by Mandiant last year, organizations that had no prior knowledge of the test were unable to detect attacks against their perimeter, even when those attacks resulted in successful compromise and a full perimeter breach.

The other reason that breaches are getting spotted sooner is that the attackers are bragging more about their successful attacks.

While criminals and state-sponsored attackers tend to stay quiet about their hacks in order to keep the data flowing, hacktivisits and cybervandals are looking for fame and impact.

Mandiant has also noted two more worrisome trends in last year's attacks.

One is that attackers are stealing sensitive information, then threatening companies with public exposure if they don't pay up.

This is different from traditional ransomware, such as Cryptolocker, where the data is encrypted and the customer has to pay up to get the decryption key. According to Carmakal, these kinds of attacks tend to be large-scale, automated, ask for relatively low ransom amounts, and can be defeated by having good backups in place.

The new extortionists target large organizations and look for information that, if made public, could put a company out of business.

These ransom amounts can range from tens of thousands of dollars up into the millions, Carmakal said.

And there is little that a company can do except pay up and hope for the best.

"If the data has already left the environment, there's really nothing you can do," he said.

However, companies should check that the hackers have the data first before paying up, he added.
