“I’m completely interested in the creative ways computers can break down,” Schultz jokes.

A use-after-free vulnerability exists in the MediaRecorder API of Webkit WebKitGTK 2.40.5. A specially crafted web page can abuse this vulnerability to cause memory corruption and potentially arbitrary code execution. A user would need to to visit a malicious webpage to trigger this vulnerability.

Plus, Qakbot appears to be still active, despite efforts from the FBI and other international law enforcement agencies to disrupt the massive botnet.

Despite the disruption to its infrastructure, the threat actors behind the QakBot malware have been linked to an ongoing phishing campaign since early August 2023 that led to the delivery of Ransom Knight (aka Cyclops) ransomware and Remcos RAT. This indicates that “the law enforcement operation may not have impacted Qakbot operators’ spam delivery infrastructure but rather only their

Cisco has released updates to address a critical security flaw impacting Emergency Responder that allows unauthenticated, remote attackers to sign into susceptible systems using hard-coded credentials. The vulnerability, tracked as CVE-2023-20101 (CVSS score: 9.8), is due to the presence of static user credentials for the root account that the company said is usually reserved for use during

The threat actors behind the Qakbot malware have been conducting a campaign since early August 2023 in which they have been distributing Ransom Knight ransomware and the Remcos backdoor via phishing emails.

A vulnerability in an API endpoint of multiple Cisco Unified Communications Products could allow an unauthenticated, remote attacker to cause high CPU utilization, which could impact access to the web-based management interface and cause delays with call processing. This API is not used for device management and is unlikely to be used in normal operations of the device. This vulnerability is due to improper API authentication and incomplete validation of the API request. An attacker could exploit this vulnerability by sending a crafted HTTP request to a specific API on the device. A successful exploit could allow the attacker to cause a denial of service (DoS) condition due to high CPU utilization, which could negatively impact user traffic and management access. When the attack stops, the device will recover without manual intervention.

A vulnerability in the on-device application development workflow feature for the Cisco IOx application hosting infrastructure in Cisco IOS XE Software could allow an authenticated, remote attacker to access the underlying operating system as the root user. This vulnerability exists because Docker containers with the privileged runtime option are not blocked when they are in application development mode. An attacker could exploit this vulnerability by using the Docker CLI to access an affected device. The application development workflow is meant to be used only on development systems and not in production systems.

A vulnerability in Cisco Emergency Responder could allow an unauthenticated, remote attacker to log in to an affected device using the root account, which has default, static credentials that cannot be changed or deleted. This vulnerability is due to the presence of static user credentials for the root account that are typically reserved for use during development. An attacker could exploit this vulnerability by using the account to log in to an affected system. A successful exploit could allow the attacker to log in to the affected system and execute arbitrary commands as the root user.
