Kaspersky security researchers have disclosed details of a brand-new ransomware family written in Rust, making it the third strain after BlackCat and Hive to use the programming language. Luna, as it’s called, is “fairly simple” and can run on Windows, Linux, and ESXi systems, with the malware banking on a combination of Curve25519 and AES

Google on Tuesday officially announced support for DNS-over-HTTP/3 (DoH3) for Android devices as part of a Google Play system update designed to keep DNS queries private. To that end, Android smartphones running Android 11 and higher are expected to use DoH3 instead of DNS-over-TLS (DoT), which was incorporated into the mobile operating system with Android

Russian threat actors capitalized on the ongoing conflict against Ukraine to distribute Android malware camouflaged as an app for pro-Ukrainian hacktivists to launch distributed denial-of-service (DDoS) attacks against Russian sites. Google Threat Analysis Group (TAG) attributed the malware to Turla, an advanced persistent threat also known as Krypton, Venomous Bear, Waterbug, and Uroburos, and linked

Two client-side risks dominate the problems with data loss and data exfiltration: improperly placed trackers on websites and web applications and malicious client-side code pulled from third-party repositories like NPM. Client-side security researchers are finding that improperly placed trackers, while not intentionally malicious, are a growing problem and have clear and significant privacy implications when

Cybersecurity researchers have taken the wraps off a previously undocumented spyware targeting the Apple macOS operating system. The malware, codenamed CloudMensis by Slovak cybersecurity firm ESET, is said to exclusively use public cloud storage services such as pCloud, Yandex Disk, and Dropbox for receiving attacker commands and exfiltrating files. “Its capabilities clearly show that the

Google has taken steps to ax dozens of fraudulent apps from the official Play Store that were spotted propagating Joker, Facestealer, and Coper malware families through the virtual marketplace. While the Android storefront is considered to be a trusted source for discovering and installing apps, bad actors have repeatedly found ways to sneak past security

Thai activists involved in the country’s pro-democracy protests have had their smartphones infected with the infamous Pegasus government-sponsored spyware. At least 30 individuals, spanning activists, academics, lawyers, and NGO workers, are believed to have been infected between October 2020 and November 2021, many of whom have been previously detained, arrested and imprisoned for their political

With speculative execution attacks remaining a stubbornly persistent vulnerability ailing modern processors, new research has highlighted an “industry failure” to adopting mitigations released by AMD and Intel, posing a firmware supply chain threat. Dubbed FirmwareBleed by Binarly, the information leaking assaults stem from the continued exposure of microarchitectural attack surfaces on the part of enterprise

Juniper Networks has pushed security updates to address several vulnerabilities affecting multiple products, some of which could be exploited to seize control of affected systems. The most critical of the flaws affect Junos Space and Contrail Networking, with the tech company urging customers to release versions 22.1R1 and 21.4.0, respectively. Chief among them is a

Although there is a greater awareness of cybersecurity threats than ever before, it is becoming increasingly difficult for IT departments to get their security budgets approved. Security budgets seem to shrink each year and IT pros are constantly being asked to do more with less. Even so, the situation may not be hopeless. There are

An emerging threat cluster originating from North Korea has been linked to developing and using ransomware in cyberattacks targeting small businesses since September 2021. The group, which calls itself H0lyGh0st after the ransomware payload of the same name, is being tracked by the Microsoft Threat Intelligence Center under the moniker DEV-0530, a designation assigned for

Researchers have disclosed details about a security vulnerability in the Netwrix Auditor application that, if successfully exploited, could lead to arbitrary code execution on affected devices. “Since this service is typically executed with extensive privileges in an Active Directory environment, the attacker would likely be able to compromise the Active Directory domain,” Bishop Fox said

VoIP phones using Digium’s software have been targeted to drop a web shell on their servers as part of an attack campaign designed to exfiltrate data by downloading and executing additional payloads. “The malware installs multilayer obfuscated PHP backdoors to the web server’s file system, downloads new payloads for execution, and schedules recurring tasks to

Following the launch of a new “Data safety” section for the Android app on the Play Store, Google appears to be readying to remove the app permissions list from both the mobile app and the web. The change was highlighted by Esper’s Mishaal Rahman earlier this week. The Data safety section, which Google began rolling

A group of academics from the New Jersey Institute of Technology (NJIT) has warned of a novel technique that could be used to defeat anonymity protections and identify a unique website visitor. “An attacker who has complete or partial control over a website can learn whether a specific target (i.e., a unique individual) is browsing

New survey reveals lack of staff, skills, and resources driving smaller teams to outsource security. As business begins its return to normalcy (however “normal” may look), CISOs at small and medium-size enterprises (500 – 10,000 employees) were asked to share their cybersecurity challenges and priorities, and their responses were compared the results with those of

The botnet behind the largest HTTPS distributed denial-of-service (DDoS) attack in June 2022 has been linked to a spate of attacks aimed at nearly 1,000 Cloudflare customers. Calling the powerful botnet Mantis, the web performance and security company attributed it to more than 3,000 HTTP DDoS attacks against its users. The most attacked industry verticals

Nation-state hacking groups aligned with China, Iran, North Korea, and Turkey have been targeting journalists to conduct espionage and spread malware as part of a series of campaigns since early 2021. “Most commonly, phishing attacks targeting journalists are used for espionage or to gain key insights into the inner workings of another government, company, or

Joshua Schulte, a former programmer with the U.S. Central Intelligence Agency (CIA), has been found guilty of leaking a trove of classified hacking tools and exploits dubbed Vault 7 to WikiLeaks. The 33-year-old engineer had been charged in June 2018 with unauthorized disclosure of classified information and theft of classified material. Schulte also faces a

Consumer electronics maker Lenovo on Tuesday rolled out fixes to contain three security flaws in its UEFI firmware affecting over 70 product models. “The vulnerabilities can be exploited to achieve arbitrary code execution in the early phases of the platform boot, possibly allowing the attackers to hijack the OS execution flow and disable some important
