What Is A Trojan Attack? Understanding The Invisible Threat
From the home office to the boardroom, cybersecurity threats are pervasive. As technology advances, cyber threats evolve, with cybercriminals continually devising new ways to breach the most robust of security systems. Of these threats, a common but often misunderstood form is the Trojan attack. So, what is a Trojan attack, and how can it impact your cybersecurity infrastructure?
Defining a Trojan Attack
Named after the Greek myth of the Trojan horse, a Trojan attack (or a Trojan virus) deceives victims into willingly opening their digital gates to a malicious entity. On the surface, this program appears legitimate, often masquerading as desirable software, an email attachment, or a hyperlink within an email. Once the unsuspecting user opens, installs, or clicks on the disguised Trojan, the harmful code is executed, potentially causing significant damage to your system or data.
Unlike computer worms and viruses, Trojans don’t replicate themselves but pave the way for cybercriminals to access and control your system. This access can result in data theft, system damage, espionage, and even the creation of a backdoor into your network for future attacks.
The Different Types of Trojan Attacks
Trojan attacks are not a monolith but rather a spectrum of malicious software, each with their unique characteristics and threat mechanisms. Some of the common types include:
- Backdoor Trojans that grant cybercriminals control over the victim’s system, allowing them to send, receive, launch, and delete files.
- Trojan-Bankers designed to steal account data for online banking systems, e-payment systems, and credit or debit cards.
- Trojan-Ransom which modifies the data on a victim’s computer in such a way that the computer won’t correctly run again until a ransom is paid.
How to Protect Your System from a Trojan Attack
Trojans exploit gaps in security protocols, lack of user awareness, and sometimes even the sophisticated tactics of social engineering. How can you fortify your systems against such invisible threats?
- Regular Updates: Ensure your systems and applications are regularly updated. These updates often include patches for security vulnerabilities that Trojans might exploit.
- Security Software: Use reliable antivirus and anti-malware software. Regular scans can help detect and eliminate Trojans before they embed themselves into your system.
- Awareness and Training: Educating your team about safe online habits can drastically reduce the chance of a Trojan breaching your security. Consider implementing regular awareness training to equip your team with the knowledge and best practices to recognise potential threats.
- Penetration Testing: Regular penetration testing can simulate cyber attacks and expose potential vulnerabilities in your system.
- Secure Email Ecosystem: As Trojans often infiltrate systems through malicious emails, securing your email ecosystem is critical. InfoTrust can help your organisation implement a secure email ecosystem, reducing the risk of email-based Trojan attacks. Our AI-based technology is able to detect suspicious text patterns, tones, malicious links, and unusual IP addresses or locations.
Understanding what a Trojan attack is and the potential damage it can cause is the first step to securing your organisation’s digital assets. Implementing robust security measures, combined with the professional cybersecurity services provided by InfoTrust, can provide a resilient defence line against Trojan attacks and other cybersecurity threats.
Stay vigilant, stay informed, and stay safe with InfoTrust. Your cybersecurity is our priority.

Mimecast recently released its State of Email Security Report for 2021. The fifth edition of its annual report used interviews with over twelve hundred of information technology and cybersecurity professionals across the globe to gather vital cybersecurity insights. The report offers an insight into the latest email threats along with advice on how to build cyber resilience and mitigate the risks of email-borne attacks.
Cyber attacks and data breaches have been commonplace in the news headlines for some time now. Although a warning from the media is certainly helpful, there is so much more that can be done when it comes to threat intelligence sharing. Threat intelligence sharing is an important part of the global cybersecurity community effort to tackle cybercrime and should form a part of every organisation’s cybersecurity strategy. Sharing cyber threat intelligence enables organisations to make informed decisions about their cybersecurity, building more effective and robust cyber defences.
One of my favourite annual reports to read is the Verizon Data Breach Investigations Report. It’s packed full of insights about the threat landscape and security leaders, in my opinion, should read this report to get a pulse on what’s happening in cyber-scape.
After all, as cyber leaders, we are here to stop breaches – so the insights gained from real cyber incidents and breaches is gold in learning how to tighten up our defences.
All businesses, large and small, are under increasing pressure to demonstrate that they are managing the risk of cyberattacks. This means having the right processes and controls in place to identify risks and vulnerabilities, protect information, as well as detect, respond, and recover in the event of cybersecurity incidents. As such, many businesses are turning to certification authorities and security frameworks to demonstrate privacy and security best practice and achieve compliance with regulatory bodies. System and Organisation Controls (SOC 2) is one such compliance framework that can help organisations to create a structured approach to cybersecurity.
Frost & Sullivan has recently released its 2021 Frost Radar: Email Security report, where its findings provide a benchmarking framework to help businesses protect their email from cyber threats.
As we operate in an increasingly digital world, every business collect, store, and share more and more data. And, amongst that data is personal information. With the OAIC marking this year’s Privacy Awareness Week (PAW) from Monday 3 May to Sunday 9 May 2021, it’s time for us all to review how we protect our customers’ personal information.
