Pardon the Intrusion # 5: In AI, we trust

Welcome to the latest issue of Pardon The Intrusion, TNW's fortnightly newsletter in which we explore the wilderness of security.

In the last newsletter, we talked about using artificial intelligence to combat malware.

This has led me to think about how to design effective machine learning models to detect malicious content, especially because of their constant evolution.

You know how it goes: cyber-saviors find a way to attack malware on computers and security managers build defense systems to prevent them. The bad guys then find another way to slip in, a new defense is built.

Enter, defend, repeat. And it continues, again and again.

I interviewed Adrien Gendre, chief architect of solutions at Vade Secure, a predictive email defense company, about it. Ultimately, this requires understanding the threats you are likely to face as a business and modeling an appropriate solution.

"When malware signatures change frequently, machine learning patterns designed to detect them lose their predictability," says Gendre. "It is essential to define malicious behavior for ML models to be effective."

But it also means that models are trained not only in the right datasets, but also in contradictory inputs, he warns.

Here's the problem: having huge amounts of training data means nothing. Appropriate data quality controls should also be put in place.

"What we need is a strong, supervised ML model based on quality data," says Gendre.

So, what does all this translate? Before adopting artificial intelligence for cybersecurity, companies must understand how they are used, whether they are effective and whether they have been applied correctly.

(TechCrunch)

Data point

New statistics released by APWG revealed that phishing attacks are at the highest level in 3 years. The total number of phishing sites detected between July and September 2019 was 266,387. This represents a 46% increase over the 182,465 observed in the second quarter of 2019 and almost double the 138,328 recorded in the fourth quarter of 2018.
