Sophos announced Sophos Intercept X for Server, next-generation server protection with predictive deep learning technology that provides constantly evolving security against cyber threats.
Sophos’ deep learning neural networks are trained on hundreds of millions of samples to look for suspicious attributes of malicious code and prevent never-before-seen malware attacks. SophosLabs research indicates that 75 percent of malware found in an organization is unique to that organization, indicating the majority of malware is previously unknown.
A recent Sophos survey reveals that two-thirds of IT managers worldwide don’t understand what anti-exploit technology is, leaving their organizations vulnerable to data breaches. Once inside a network, cybercriminals can use persistent and lateral moves to target and takeover servers to access the high-value data stored there, such as personally-identifiable information (PII), banking, tax, payroll and other financial records, proprietary intellectual properties, shared applications – all of which can be sold on the Dark Web or used for other types of attacks and monetary gain. Servers can also suffer collateral damage from ransomware and run-of-the-mill cyberattacks. Attacks reaching servers can be more devastating to a business than attacks on endpoints, due to the critical data they hold.
Sophos demonstrates hacking and advanced exploit techniques that cybercriminals use in this Video of How Active Adversaries Attack in Real-Time (also found on Sophos.com/Servers).
“Servers are the bullseye for cybercriminals because they store valuable information and have a broader, system-wide organizational purpose than individual endpoints. An entire company could get potentially wiped out if cybercriminals infiltrate its servers with ransomware or malicious code, or exploit vulnerabilities to gain access. Once breached, attackers can get deep in the network and have the ability to do some serious damage, as well as exfiltrate data,”said Sunil Sharma, Managing Director Sales for Sophos India & SAARC. “Cybercriminals use stolen information for their own spear-phishing campaigns and crime sprees, or they could resell it at a premium price on the Dark Web or to a private network of buyers. Sophos threat experts have seen access to compromised servers for sale on the Dark Web, in addition to the poached data itself – a bonus for cybercriminals, but a double whammy for businesses.”
Attackers also use breached servers as proxies to redirect traffic to malicious websites and are now installing cryptominers on server farms and cloud accounts, so they can generate crypto-currencies by stealing a company’s CPU, RAM, electricity, and other resources. The motives of cybercriminals based on how servers are utilized, what’s stored there and what can be leveraged for multiple crimes underscores the need for predictive, server-designed security with advanced anti-exploit technology that helps protect even unpatched systems.
“According to The Dirty Secrets of Network Firewalls research conducted by Sophos, 89 percent IT managers in India opined that stopping malware threats have become harder over the last year and only endpoint or firewall is not sufficient to protect our data. It’s time we realize that servers are critical infrastructure, but they are often overlooked in the endpoint strategy of many companies,” said Sharma. “It’s not enough to simply install traditional endpoint protection on servers because they demand additional tools and features, such as cloud workload discovery, including Microsoft Azure and Amazon Web Services, and protection to mitigate risk from rogue or forgotten IT assets. The survey also said that 65% Indian respondents completely agree that their current defenses are not sufficient to block cyber threats – be it network, endpoint or server. Server-specific protection is necessary to a successful layered security strategy to reduce the risk of a data breach. Combined with Sophos’ Synchronized Security intelligence sharing and easy management from our Sophos Central dashboard, Intercept X for Server is a powerful addition that helps defend businesses from becoming the next victim.”
The need for server protection exists in organizations of all sizes, with smaller businesses being potentially at more risk than larger, better resourced enterprises as Frank Dickson, research vice president, Security Products with IDC commented, “The small- and mid-sized markets (SMBs) face challenges for server protection as they need the same level of protection as their enterprise counterparts, yet protection must be in an extremely easy to use offering. Additionally, sadly, SMBs are too often tempted to use underpowered, inappropriate PC endpoint offerings to protect servers as a way to save cost, forcing SMB server security vendors to provide compelling, affordable offerings that are also appropriate for a smaller or understaffed IT department.”
Regarding Sophos’ approach directly, Dickson continued, “Sophos addresses the ease-of-use factor by integrating their products on Sophos Central, so there’s one dashboard for Partners and customers to manage each security layer regardless of being on premise or in the cloud. The new Intercept X for Server significantly advances server protection with deep learning, anti-exploit and other key technology elements. The anti-exploit technology has a client right on the server, a necessary requirement based on the manner in which hackers leverage server vulnerabilities to breach systems. Given the readily available and inexpensive exploit kits for sale on the Dark Web, even cybercriminals with little expertise can launch powerful attacks, making sophisticated, server specific protection a fundamental requirement.”
Sophos partners familiar with the new product echoed Dickson’s observations:
“Sophos understands that servers need their own set of security criteria, like the lockdown feature in the current server solution, and the new ability to discover cloud workloads. Many of Riverlite’s clients, companies with under-staffed IT personnel, require us to keep cloud deployments secure and free from disruption,” said Simon Barnes, principal consultant at Riverlite in St. Neots, Cambridgeshire, UK. “Having assets in the cloud or migrating and using public clouds can be daunting to any business. It’s important that MSPs have the right security in place to protect these ‘invisible’ servers, which are easily forgotten from an overall security strategy. This type of exposure weakens a company’s security posture. If any unprotected server is attacked it can wreak havoc on an entire business. We’re looking forward to upgrading and adding Intercept X for Server to our customers’ security portfolios.”
Syndesi is a Managed Service Provider (MSP) with particular interest in the unique cyber security challenges faced by the education sector, including data theft, disruption of operations and compromised technology assets. “For attackers, K-12 schools are a particularly attractive target because they store and handle the personal data of students, parents and staff. Many school districts are vulnerable due to budgetary constraints or limited IT resources, making them an easy target,” said Paul Gibbs, vice president of Syndesi Solutions, based in Athens, Alabama. “An integrated, layered security system that stops ransomware, malware and data theft is paramount. We can now add Intercept X for Server with deep learning technology and Synchronized Security to strengthen the protection of sensitive assets stored on school servers and at other customer sites. We’ve already seen situations where Sophos Intercept X has blocked ransomware on endpoints almost immediately after its first appearance. If servers are hit with ransomware or malware, it’s devastating, so we’re excited for this quick response and the synchronized intelligence-sharing at the server layer as well.”

Critical Vulnerability Discovered in Instagram App by Researchers
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.
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.
