How to decode a data breach notice – TechCrunch

Read: “We don’t know who’s to blame, but don’t blame us.”

If a system was exposed or left online without a password, you’d blame the company for lax security controls. If a good-faith security researcher finds and reports an unprotected system, for example, there’s no reason to paint them as a malicious actor. Companies love to shift the blame, so keep an open mind.

In a lot of cases, most hackers are long gone by the time a company learns of a breach. When a company says it took immediate steps, don’t assume it’s from the moment of the breach.

Equifax said it “acted immediately” to stop its intrusion, which saw hackers steal nearly 150 million consumers’ credit records. But hackers had already been in its system for two months before Equifax found the suspicious activity.

Some companies use the term “forensics” loosely. Internal investigations are not transparent or accountable, and their outcomes are rarely scrutinized or published.

However, incident responders are independent, qualified assessors that will tell a company what it needs to hear and not what it wants to hear — even if their findings may still remain private.

Don’t think for a second that a company is doing “the right thing” by disclosing a security incident. In the U.S. and Europe, companies aren’t given a choice.

Most states have some form of a data breach notification law that compels companies to disclose incidents that affect a certain number of residents and above. Failing to disclose a breach can lead to massive penalties.

Just because a company says it was hit by a “sophisticated” cyberattack doesn’t mean it was. It’s hyperbole, designed to serve as a “cover your ass” statement to downplay a security incident.What it really tells you is that the company has no idea how the attack happened.

After all, some of the biggest breaches in history happened because of unpatched systems , weak passwords or because someone clicked on a malicious email.

Read: “That we know of.”

“No evidence” doesn’t mean that something hasn’t happened, it’s that it hasn’t been seen yet. Either the company isn’t looking hard enough or it doesn’t know. Even if a company says it has “no evidence” that data was stolen, it’s worth asking how it arrived at that conclusion.

Read: “It sounds way worse if we say ‘millions’ of users.”

The next time you see a data breach notification that says only a “small percentage” of customers are affected by a breach, think again.

Houzz admitted a data breach in January 2019, in which it said “some of our user data” was taken. Months later, a hacker posted some 57 million Houzz user records. If a company doesn’t tell you how many people are affected, it’s because they don’t know — or they don’t want you to know.
