Keeping Up with the Cybercriminals

What do supermarkets, video games and search engines have in common? They all belong to sectors that have seen major hacks over the last few years. The cyberattacks on Tesco Banking, Sony and Yahoo, are just some of the most public examples in demonstrating that the ‘hacker industry’ is continuing to gather strength, attacking vulnerabilities in both the public and private sector for profit.
From corporate industries and political groups, to universities and healthcare systems – even Twitter – no one is immune. And yet cyber security is still misunderstood, or worse, underestimated. Cyber criminals are becoming more creative; for each loophole we close or flaw we patch, hackers continually are finding new methods to beat defences.
As I scan the cyber horizon looking for emerging threats, here are just a few of the key areas at risk:
Perhaps the area of highest risk, the threats to web applications are not new but they are increasing. Worryingly, we are seeing more malware targeted specifically at web applications, rather than aimed directly at end points, such as devices or users.
The move towards cloud-based software means that more data than ever is available through the web, presenting a potentially low friction access point for hackers to gain entry to an organisation’s network.
Spear Phishing Attacks:
The second area that has seen a major increase is spear phishing attacks. Far more dangerous than the general phishing scams that have been prevalent since the mid-nineties, the new generation uses targeted attacks against specific organisations. They often include malware tailored for the victim’s organisation and which meet the hacker’s objective.
To illustrate, a spear phishing attack may include malware specifically designed for a certain organisation’s end points, or some of the capabilities and applications within the target victim’s environments. These targeted attacks, when combined with the nature of the malware that’s sent, can be even more damaging.
The Internet of Things:
Although a relatively new phenomenon, the Internet of Things (IoT) – connected devices – is already being targeted by cyber criminals. There are a growing number of applications that aren’t built from traditional platforms, or unique commercial-off-the-shelf products (COTS) in the way you would normally think of COTS products. Instead, they are one-offs designed for a specific function and tend to have underlying systems that are fairly unique and have received limited vulnerability testing.
In the recent past, the potential security vulnerabilities of IoT devices were not a main concern. However, with more and more malware being specifically designed to take advantage of the vulnerabilities of IoT appliances and their capabilities to access a network, not to mention botnets, IoT has quickly jumped up the CIO’s agenda.
Another area expected to see more attacks is at the firmware level. As organisations have moved to the cloud, much of the malware that’s been designed looks to attack within the container of the hosted tenant. For instance, as the hosted tenant migrates their standard operating systems and applications, the malware is deployed against those systems.
More attacks and malware specifically designed for one layer deeper are expected at either the firmware or the orchestration layer. The virtualisation layer could also be a target as it would potentially allow an attacker to compromise more than just the single container. The risk of such attacks has a massive impact on cloud vendors as well as other types of hosting providers.
What’s a Company to Do?
Businesses need to approach the security of their environments in a comprehensive manner, looking at every level of the technology stack to see where a potential new or existing vulnerability could originate and/or be exploited. Some of the proactive measures all organisations can follow to guard against any form of cyberattack:
- Implement a Defence in Depth model
- Network edge security
- Invest in Intrusion Detection and Prevention software
- Install robust firewalls including Web Application Firewalls
- Conduct regular vulnerability scans
- Penetration testing
- Safeguard VPN access
- Adopt a virtual desktop environment for remote devices.
- Block users from installing unauthorised applications
- Insist on strong password controls for users
- Adhere to basic security doctrines
- Disable macro scripts
- Implement proxy internet access
- Segregate networks
- Backup regularly and verify the integrity of those backups
- Draw up an Information Security Policy
- Create an education programme for users
- Develop a practical incident response plan.
With so many moving parts and layers within the business, and so many routes towards ensuring the security of environments, networks, and applications, pairing with an expert security partner can help. Not only can this augment resources, it means you have an army of knowledge on your side, ready to identify, take on and overcome the ever changing and emerging threat-scape all companies face.
