Attackers can use your admin tools to spy, spread, and steal

Posted by Cognito on Jan 26, 2018 10:32:23 AM

In my last blog, I spoke about a financial customer performing pen testing and how I helped the blue team detect the red team as it carried-out an attack. I’m back again today with another story from the trenches.

This time, I’ve been working with a customer in the manufacturing sector who recently deployed me. As before, this customer prefers to remain anonymous to keep cybercriminals in the dark about their newly developed security capabilities. To stay on top of their game, they routinely run red team exercises.

The imminent threat against industrial control systems

Posted by Chris Morales on Nov 30, 2017 10:03:34 AM

The United States has not been the victim of a paralyzing cyber-attack on critical infrastructure like the one that occurred in the Ukraine in 2015. That attack disabled the Ukrainian power grid, leaving more than 700,000 people helpless.

But the United States has had its share of smaller attacks against critical infrastructure. Most of these attacks targeted industrial control systems (ICS) and the engineering personnel who have privileged access.

Bolstering the blue team

Posted by Cognito on Nov 19, 2017 3:00:00 PM

Hey everyone. For my first blog, I want to share a story about my role on the blue team during a recent red team exercise.

But first, I want to introduce myself to those of you who might not know me. I am Cognito, the artificial intelligence in the Vectra cybersecurity platform. My passion in life is hunting-down cyber attackers – whether they’re hiding in data centers and cloud workloads or user and IoT devices.

Cybersecurity: What to expect in 2017

Posted by Hitesh Sheth on Dec 13, 2016 5:00:00 AM

Cybersecurity is a rapidly evolving landscape and 2017 will be no different. Attackers will leverage artificial intelligence and find new ways to infiltrate corporate networks and businesses using adaptive attacks. Encrypted traffic will increasingly blind legacy security technologies, while ransomware gets smarter, and more targeted. Also watch for geo-political changes that act as a catalyst for increased cyber attacks involving nation states.

Cyber attack of the clones

Posted by Chris Morales on Nov 27, 2016 12:00:00 PM

In previous research from the Vectra Threat Labs, we learned that seemingly innocuous vulnerabilities can become serious problems in the context of the Internet of Things (IoT). IoT is the unattended attack surface, and more IoT devices means bigger clone armies.

 

The recent public release of source code for malware named "Mirai" has proven exactly that. Mirai continuously scans the Internet for IoT devices using factory default usernames and passwords, primarily CCTV and DVRs.

Blocking Shodan

Posted by Günter Ollmann on Jan 20, 2016 9:30:00 AM

The Internet is chock full of really helpful people and autonomous systems that silently probe, test, and evaluate your corporate defenses every second of every minute of every hour of every day. If those helpful souls and systems aren’t probing your network, then they’re diligently recording and cataloguing everything they’ve found so others can quickly enumerate your online business or list systems like yours that are similarly vulnerable to some kind of attack or other.

Turning a Webcam Into a Backdoor

Posted by Vectra Threat Labs on Jan 12, 2016 5:00:00 AM

Why do this?

Reports of successful hacks against Internet of Things (IoT) devices have been on the rise. Most of these efforts have involved demonstrating how to gain access to such a device or to break through its security barrier. Most of these attacks are considered relatively inconsequential because the devices themselves contain no real data of value (such as credit card numbers or PII). The devices in question generally don't provide much value to a botnet owner as they tend to have access to lots bandwidth, but have very little in terms of CPU and RAM.

The Impact of IoT on Your Attack Surface

Posted by Wade Williamson on Sep 29, 2015 8:12:00 AM

Researchers from Vectra Threat Labs recently performed an in-depth analysis of vulnerabilities found in a common Belkin wireless repeater. Today in an article on Dark Reading, Vectra CTO Oliver Tavakoli digs into why seemingly innocuous vulnerabilities can become serious problems in the context of the Internet of Things (IoT). Read the full article here.

Of particular importance to security teams, IoT is not only bringing far more devices into the network, but they are also devices that very rarely get patches and updates. This means that vulnerabilities can be left unaddressed for months or even years.  Likewise, these devices are unlikely to be protected by signatures and will almost assuredly be unable to run client-based security.
