Hackers are targeting Cisco Adaptive Security Appliance SSL VPNs in credential stuffing and brute-force attacks that take advantage of lapses in security defenses, such as not enforcing multi-factor authentication. Last week, BleepingComputer reported that the Akira ransomware gang was breaching Cisco VPNs for initial network access.

The Cisco Talos report exposes new malware used by the group to target Internet backbone infrastructure and healthcare organizations in the U.K. and the U.S. Two reports from cybersecurity company Cisco Talos provide intelligence about a new attack campaign from the North Korean threat actor Lazarus. The researchers observed the Lazarus group successfully compromise an internet backbone infrastructure provider in the U.K. in early 2023, deploying a new malware dubbed QuiteRAT. The initial compromise was done via exploitation of the CVE-2022-47966 vulnerability, which affects Zoho's ManageEngine ServiceDesk.

There's mounting evidence that Akira ransomware targets Cisco VPN products as an attack vector to breach corporate networks, steal, and eventually encrypt data. Akira ransomware is a relatively new ransomware operation launched in March 2023, with the group later adding a Linux encryptor to target VMware ESXi virtual machines.

In alliance with Cohesity and others, Cisco is fueling near-zero latency between ransomware detection and remediation with its Extended Detection and Response platform. Remediation is a capability that Cisco has added to its XDR platform, which the company announced at the RSA conference in April and launched for general availability globally on Tuesday.

Learn how a malicious driver exploits a loophole in the Windows operating system to run at kernel level. Cisco Talos discovered a new Microsoft Windows policy loophole that allows a threat actor to sign malicious kernel-mode drivers executed by the operating system.

Cisco warned customers today of a high-severity vulnerability impacting some data center switch models and allowing attackers to tamper with encrypted traffic.Tracked as CVE-2023-20185, the flaw was found during internal security testing in the ACI Multi-Site CloudSec encryption feature of data center Cisco Nexus 9000 Series Fabric Switches.

Proof-of-concept exploit code for the high-severity vulnerability in Cisco Secure Client Software for Windows and Cisco AnyConnect Secure Mobility Client Software for Windows has been published. Cisco Secure Client Software - previously known as Cisco AnyConnect Secure Mobility Client - is unified endpoint security software designed to assist businesses in expanding their network access capabilities and enabling remote employees to connect via both wired and wireless connections, including VPN. In early June, Cisco published a security advisory about CVE-2023-20178, a vulnerability in the client update process of both Cisco AnyConnect Secure Mobility Client Software for Windows and Cisco Secure Client Software for Windows.

Proof-of-concept exploit code is now available for a high-severity flaw in Cisco Secure Client Software for Windows that can let attackers elevate privileges to SYSTEM. Cisco Secure Client helps employees to work from anywhere using a secure Virtual Private Network and provides network admins with telemetry and endpoint management features.Cisco released security updates to address this security bug last Tuesday when it said its Product Security Incident Response Team did not have evidence of malicious use or public exploit code targeting the bug in the wild.
