Continuous Response Needed To Fight Modern Threats – Tim Orchard, F-Secure

Published

on

As the threat landscape continues to evolve, so does the need for organizations’ approaches to defending against the business impact of cyber attacks.

In light of this trend, cybersecurity provider F-Secure is calling for greater emphasis on both the preparedness for a breach as well as fast and effective containment that covers the correct balance of people, process and technology.

“Cyber breaches are now a fact of life for many companies. It’s no longer a matter of ‘if’ a company will be breached, the question is ‘when’. And that calls for a shift in how organizations handle many aspects of security,” said F-Secure Countercept Managing Director Tim Orchard.

Research highlights one current area of weakness as the lack of investment in effective incident response strategies. 44 percent of respondents to a recent MWR Infosecurity (acquired by F-Secure in 2018*) survey said they invested less in their response capabilities than in threat prediction, prevention, or detection. Only 12 percent said the response was prioritized over their other security capabilities.

The continuous response, the art, and science of having the right people in the right place at the right time armed with the information they need to take control of the situation, is an emerging concept in cybersecurity that’s central to boosting response capabilities. The aim is to combine elements of collaboration, context, and control into a fluid process. In practice, this could mean a single team of threat hunters, first responders, administrators, and other personnel working together to actively identify and remediate potential threats before they escalate.

“Having the tools and techniques in place to quickly detect, contain and frustrate attacks as they unfold buys you time, and gives you an opportunity to understand the full picture about how attackers are exploiting your weaknesses and moving through your network. And they need to be sophisticated enough to avoid tipping off an attacker that you’re onto them, and prepared to evict them in one concerted push,” explained Orchard. “And it’s important to put these tools and techniques into the hands of the right team if you want them to work.”

The MDR blend of collaboration, context, and control

According to the Gartner’s “Answers to Questions About 3 Emerging Security Technologies for Midsize Enterprises”* report, “MDR is about ’renting trained eyes’ you can’t find or afford to detect incidents that go undiscovered…It’s about finding the 10% of incidents that bypass traditional firewall and endpoint protection security.”

MDR solutions typically offer 24/7 threat monitoring, detection, and response services that leverage advanced analytics and threat intelligence to help protect organizations. Generally, MDR vendors deploy sensors (such as an endpoint agent or a network probe) to gather data from a client’s systems. The data is then analyzed for evidence of compromise and the client is notified when a potential incident is detected.

After detection, clients either respond on their own or bring in external IR teams and approaches, which can include local or remote investigations and forensics, as well as advice on a possible orchestrated technical response. But at best, response activities stop at isolating hosts using EDR agents or firewalling.

But effective solutions can potentially do much more. Treating response as a continuous activity means team members will be in constant communication and collaboration with one another, able to discuss suspicious events happening anywhere within their infrastructure. MDR solutions can facilitate this process, giving defenders the edge they need to stop, contain, and ultimately, eject an adversary.

“Finding a balanced MDR solution, regardless of whether its an in-house solution or outsourced, is key. I think our approach to preparing our clients to assume the breaches have already happened, and then help them hunt down those threats, is the essence of continuous response,” said Orchard. “Getting this right lets defenders evict attackers quickly on their first try, and prevent those adversaries from repeating their attack.”

Critical Vulnerability Discovered in Instagram App by Researchers

Published

on

By

Instagram is one of the most popular social media platforms globally, with over 100+ million photos uploaded every day, and nearly 1 billion monthly active users. Individuals and companies share photos and messages about their lives and products to their followers globally.  So imagine what could happen if a hacker was able to completely take over Instagram accounts, and access all the messages and photos in those accounts, post new photos or delete or manipulate existing photos.  What could that do to a person’s or company’s reputation? 

Earlier this year, Check Point researchers found a critical vulnerability in the Instagram app that would have given an attacker the ability to take over a victim’s Instagram account, and turn their phone into a spying tool, simply by sending them a malicious image file. When the image is saved and opened in the Instagram app, the exploit would give the hacker full access to the victim’s Instagram messages and images, allowing them to post or delete images at will, as well as giving access to the phone’s contacts, camera and location data. 

Here’s how we found the vulnerability, and worked with Facebook and Instagram to close it to keep users safe.

What are the apps on your phone permitted to do?
Wherever we go, our mobile phones usually go with us, to keep us in touch with families, loved ones and our work, too. Of course, this is also why mobiles are an attractive target for hackers.  Not only can they steal data and credentials from our phones, but they can also use them for spying on us: tracking our location, listening to conversations, and accessing our data and messages.

Fortunately, all modern mobile operating systems include several layers of protection against this type of malicious activity. These protections usually rely on the basic concept of ‘application isolation’ – even if someone was able to hack a specific application, they would still be confined to that application alone, along with its strict permissions, and would not be able to extend their hacking attempt any further.

The key term here is “strict permissions” – for example, a map application should be able to access your location, but should not have access to your microphone; a dating app should be able to access your camera and nothing else, and so on.

But what happens when we`re talking about an application that has extensive permissions on your device?  If the application is hacked, the hacker will have easy access to your GPS data, camera, microphone, contacts, and more. 

Fortunately, there isn’t a huge list of apps that have such extensive permissions on users’ devices.   One example is Instagram. Given its popularity and wide-ranging permissions, we decided to review the security of Instagram’s mobile app for both Android and iOS operating systems.

What did we find?
Our research revealed a critical vulnerability that might allow the attackers what is technically referred to as – remote code execution (RCE). This vulnerability can allow an attacker to perform any action they wish in the Instagram app (yes, even if it is not actually a part of the application logic or features). Since the Instagram app has very extensive permissions, this may allow an attacker to instantly turn the targeted phone into a perfect spying tool – putting the privacy of millions of users at serious risk.

Modus operandi

So how does such a popular application include vulnerabilities, when huge amounts of time and resources are invested in developing it?
The answer is that most modern app developers do not actually write the entire application on their own: if they did so it would take years to write an application. Instead, they use 3rd party libraries to handle common (and often complicated) tasks such as image processing, sound processing, network connectivity, and so on. This frees the developers to handle only the coding tasks, which represent the apps core business logic. However, this relies on those 3rd party libraries being completely trustworthy and secure.

Our modus operandi for this research was to examine the 3rd party libraries used by Instagram, And the vulnerability we found was in the way that Instagram used Mozjpeg- an open source project used by Instagram as its JPEG format image decoder for images uploaded to the service.

A bad image: hacking and taking over the user’s mobile Instagram account
In the attack scenario we describe in our research, an attacker can simply send an image to their target victim via email, WhatsApp or another media exchange platform. The target user saves the image on their handset, and when they open the Instagram app, the exploitation takes place, allowing the attacker full access to any resource in the phone that is pre-allowed by Instagram.

These resources include contacts, device storage, location services and the device camera. In effect, the attacker gets full control over the app and can create actions on behalf of the user, including reading all of their personal messages in their Instagram account and deleting or posting photos at will.  This turns the device into a tool for spying on targeted users without their knowledge, as well as enabling malicious manipulation of their Instagram profile. In either case, the attack could lead to a massive invasion of users’ privacy and could affect reputations – or lead to security risks that are even more serious.

At a basic level, this exploit can be used to crash a user’s Instagram app, effectively denying them access to the app until they delete it from their device and re-install it, causing inconvenience and possible loss of data. 

Responsible disclosure & Protection

We have responsibly disclosed our findings to Facebook and the Instagram team. Facebook’s advisory was very responsive and helpful, they have described this vulnerability as an “Integer Overflow leading to Heap Buffer Overflow” and issued a patch to remediate the issue on the newer versions of the Instagram application on all platforms.

The patch for this vulnerability has already been available for 6 months prior to this publication, giving time to the majority of users to update their Instagram applications, thus mitigating the risk of this vulnerability being exploited. We strongly encourage all Instagram users to ensure they are using the latest Instagram app version and to update if any new version is available.

Check Point’s SandBlast Mobile (SBM) provides full visibility into mobile risks, with advanced threat prevention capabilities. With the market’s highest threat catch rate, users of SBM stay protected from malware, phishing, man-in-the-middle attacks, OS exploits, and more. Intuitive to use, users only hear from SandBlast Mobile if they are under attack.
