Cyber Threat Intelligence Sharing in Nigeria (2024)
Presentation / Conference Contribution

Cybersecurity challenges are common in Nigeria. Sharing cyber threat intelligence is essential in addressing the extensive challenges posed by cyber threats. It also helps in meeting regulatory compliance. There are a range of impediments that preven... Read More about Cyber Threat Intelligence Sharing in Nigeria.

FACO: Fuzzy Ant Colony Optimization for Attack Detection in Smart Water Security using Few-Shot Learning (2024)
Presentation / Conference Contribution

In the realm of smart water utilities, the increasing sophistication of cyber threats presents a significant challenge to the security and operational integrity of water and wastewater treatment facilities. These facilities, heavily dependent on Indu... Read More about FACO: Fuzzy Ant Colony Optimization for Attack Detection in Smart Water Security using Few-Shot Learning.

Factors Amplifying or Inhibiting Cyber Threat Intelligence Sharing (2024)
Presentation / Conference Contribution

The increasing frequency of cyberattacks by criminal and state-sponsored actors, has elevated the importance of cyber threat intelligence for organisations. We are interested to understand why practitioner share cyber threat intelligence and the impe... Read More about Factors Amplifying or Inhibiting Cyber Threat Intelligence Sharing.

Ret-gadgets in RISC-V-based Binaries Resulting in Traps for Hijackers (2023)
Presentation / Conference Contribution

The presence of instructions within executable programs is what makes the binaries executable. However, attackers leverage on the same to achieve some form of Control Flow Hijacking (CFH). Such code re-use attacks have also been found to lead to De... Read More about Ret-gadgets in RISC-V-based Binaries Resulting in Traps for Hijackers.

Forensic Trails Obfuscation and Preservation via Hard Drive Firmware (2022)
Presentation / Conference Contribution

The hard disk drive stores data the user is creating, modifying, and deleting while a firmware facilitates communication between the drive and the operating system. The firmware tells the device and machine how tocommunicate with each other and will... Read More about Forensic Trails Obfuscation and Preservation via Hard Drive Firmware.

Talos: A prototype Intrusion Detection and Prevention system for profiling ransomware behaviour (2021)
Presentation / Conference Contribution

In this paper, we profile the behaviour and functionality of multiple recent variants of WannaCry and CrySiS/Dharma, through static and dynamic malware analysis. We then analyse and detail the commonly occurring behavioural features of ransomware. Th...

Inter-Process CFI for Peer/Reciprocal Monitoring in RISC-V-Based Binaries (2021)
Presentation / Conference Contribution

Attacks stemming from software vulnerabilities that cause memory corruption often result in control flow hijacks and hold a place of notoriety in software exploitation. Attackers take advantage of vulnerabilities due to programming flaws to execute m... Read More about Inter-Process CFI for Peer/Reciprocal Monitoring in RISC-V-Based Binaries.

Towards Cyber-User Awareness: Design and Evaluation (2020)
Presentation / Conference Contribution

Human reliance on interconnected devices has given rise to a massive increase in cyber activities. There are about 17 billion interconnected devices in our World of about 8 billion people. Like the physical world, the cyber world is not void of entit... Read More about Towards Cyber-User Awareness: Design and Evaluation.

Mitigating Return Oriented Programming (2019)
Presentation / Conference Contribution

Code-reuse attack techniques, such as Return Oriented Programming (ROP), pose a significant threat to modern day systems as they are able to circumvent both traditional and more modern protection mechanisms such as antivirus, antimalware, Address Spa...

Policing The Cyber Threat: Exploring the Threat from Cyber Crime and the Ability of Local Law Enforcement to Respond (2018)
Presentation / Conference Contribution

The landscape in which UK policing operates today is a dynamic one, and growing threats such as the proliferation of cyber crime are increasing the demand on police resources. The response to cyber crime by national and regional law enforcement agenc...

An analysis of loop formation in OLSRv2 in ad-hoc networks and limiting its negative impact (2008)
Presentation / Conference Contribution

Transient routing loops have been observed to form in Ad-hoc Networks running the OLSRv2 routing protocol. The looping traffic significantly increases the impact on the surrounding network and its traffic thus degrading end-to-end transmission by a s...
