A stealthy Unified Extensible Firmware Interface (UEFI) bootkit called BlackLotus has become the first publicly known malware capable of bypassing Secure Boot, making it a potent threat in the cyber landscape. "This bootkit can run even on fully up-to-date Windows 11 systems with UEFI Secure Boot enabled," Slovak cybersecurity company ESET said in a report shared with The Hacker News. UEFI

Google has announced the general availability of client-side encryption (CSE) for Gmail and Calendar, months after piloting the feature in late 2022. The data privacy controls enable "even more organizations to become arbiters of their own data and the sole party deciding who has access to it," Google's Ganesh Chilakapati and Andy Wen said. To that end, users can send and receive emails or

A vulnerability in Imperative framework which allows already-privileged local actors to execute arbitrary shell commands via plugin install/update commands, or maliciously formed environment variables. Impacts Zowe CLI.

IBM HTTP Server 8.5 used by IBM WebSphere Application Server could allow a remote user to cause a denial of service using a specially crafted URL. IBM X-Force ID: 248296.

On Feb 15, 2023, the following vulnerability in the ClamAV scanning library was disclosed: A vulnerability in the HFS+ partition file parser of ClamAV versions 1.0.0 and earlier, 0.105.1 and earlier, and 0.103.7 and earlier could allow an unauthenticated, remote attacker to execute arbitrary code. This vulnerability is due to a missing buffer size check that may result in a heap buffer overflow write. An attacker could exploit this vulnerability by submitting a crafted HFS+ partition file to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to execute arbitrary code with the privileges of the ClamAV scanning process, or else crash the process, resulting in a denial of service (DoS) condition. For a description of this vulnerability, see the ClamAV blog ["https://blog.clamav.net/"].

On Feb 15, 2023, the following vulnerability in the ClamAV scanning library was disclosed: A vulnerability in the DMG file parser of ClamAV versions 1.0.0 and earlier, 0.105.1 and earlier, and 0.103.7 and earlier could allow an unauthenticated, remote attacker to access sensitive information on an affected device. This vulnerability is due to enabling XML entity substitution that may result in XML external entity injection. An attacker could exploit this vulnerability by submitting a crafted DMG file to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to leak bytes from any file that may be read by the ClamAV scanning process.

Cryptocurrency companies are being targeted as part of a new campaign that delivers a remote access trojan called Parallax RAT. The malware "uses injection techniques to hide within legitimate processes, making it difficult to detect," Uptycs said in a new report. "Once it has been successfully injected, attackers can interact with their victim via Windows Notepad that likely serves as a

Active IQ Unified Manager for VMware vSphere, Linux, and Microsoft Windows versions prior to 9.11P1 are susceptible to a vulnerability which allows unauthorized users to update EMS Subscriptions via unspecified vectors.

The framework-as-a-service signals an intensification of the cat-and-mouse game between defenders detecting lateral movement, and cybercriminals looking to go unnoticed.
