A Trojan malware attack is a type of malicious code or software that disguises itself as a legitimate program or file to trick users into executing it. Once executed, the Trojan can perform various harmful actions on the infected system or network, such as stealing data, deleting files, or installing other malware. There are different types of Trojan malware attacks, depending on their purpose and behavior. Two common types are:

Rootkit: A rootkit is a type of Trojan that hides itself and other malware from detection and removal by antivirus software or system tools. A rootkit can modify the operating system or the firmware of the device to gain persistent and privileged access to the system. A rootkit can also intercept and manipulate system calls, network traffic, or user input to conceal its activities or redirect them to malicious servers.

Backdoor: A backdoor is a type of Trojan that creates a secret or unauthorized access point to the infected system or network. A backdoor can allow an attacker to remotely control the system, execute commands, upload or download files, or monitor the system activity. A backdoor can also be used to install other malware or launch further attacks on other systems or networks.

WannaCry ransomware is a type of malware that encrypts the files on the infected devices and demands a ransom for their decryption. It exploits a vulnerability in the Windows SMB protocol that allows remote code execution. To prevent WannaCry ransomware from spreading to all clients, IT should take the following precautions:

Ensure that noncompliant endpoints are segmented off to contain any potential damage. This means that any device that is not patched, managed, or compliant with the security policies should be isolated from the rest of the network and given limited access to resources. This can be done using Cisco Identity Services Engine (ISE) and Cisco TrustSec, which can enforce dynamic segmentation based on the device’s identity, posture, and context. This way, IT can prevent the ransomware from infecting other devices and reduce the impact of the attack12

Perform a posture check to allow only network access to those Windows devices that are already patched. This means that IT should verify that the devices have installed the latest security updates from Microsoft that fix the SMB vulnerability. This can be done using Cisco AnyConnect Secure Mobility Client, which offers a VPN Posture/HostScan Module and an ISE Posture Module. Both modules can assess the endpoint’s compliance for things like operating system, patches, antivirus, antispyware, and firewall software. If the device is not patched, it can be denied access to the network or redirected to a remediation portal13

Using an Internet browser to access cloud-based service creates the risk of insecure implementation of API. API stands for Application Programming Interface, which is a set of rules and protocols that allow different applications or services to communicate and exchange data. API is often used to access cloud-based service, such as software as a service (SaaS), platform as a service (PaaS), or infrastructure as a service (IaaS). However, if the API is not implemented securely, it can expose sensitive data or allow unauthorized access to the cloud service. For example, an API may not use encryption, authentication, or authorization mechanisms to protect the data in transit or at rest. An API may also have vulnerabilities such as injection, broken authentication, or insufficient logging and monitoring, which can be exploited by attackers to compromise the cloud service or the user’s browser. Therefore, it is important to follow the best practices and standards for secure API development and testing, such as OWASP API Security Top 10. References:

Explanation

FlexVPN is an IKEv2-based VPN technology that provides several benefits beyond traditional site-to-site VPN implementations. FlexVPN is a standards-based solution that can interoperate with non-Cisco IKEv2

implementations. Therefore FlexVPN can support a multivendor environment. All of the three VPN technologies support traffic between sites (site-to-site or spoke-to-spoke).
