Samsung Introduces New Feature to Protect Users from Zero-Click Malware Attacks

Samsung Introduces New Feature to Protect Users from Zero-Click Malware Attacks

Feb 20, 2023 Mobile Security / Zero Day
Samsung has announced a new feature called Message Guard that comes with safeguards to protect users from malware and spyware via what's referred to as zero-click attacks . The South Korean chaebol said the solution "preemptively" secures users' devices by "limiting exposure to invisible threats disguised as image attachments." The security feature, available on Samsung Messages and Google Messages, is currently limited to the Samsung Galaxy S23 series, with plans to expand it to other Galaxy smartphones and tablets later this year that are running on One UI 5.1 or higher. It's also the latest security guardrail erected by Samsung, which also includes the Knox security platform that the company said already offers protection from attacks using video and audio formats. Zero-click attacks are highly-targeted and sophisticated attacks that exploit previously unknown flaws (i.e., zero-days) in software to trigger execution of malicious code without re

Twitter Limits SMS-Based 2-Factor Authentication to Blue Subscribers Only

Twitter Limits SMS-Based 2-Factor Authentication to Blue Subscribers Only

Feb 18, 2023 Authentication / Online Security
Twitter has announced that it's limiting the use of SMS-based two-factor authentication (2FA) to its Blue subscribers. "While historically a popular form of 2FA, unfortunately we have seen phone-number based 2FA be used – and abused – by bad actors," the company  said . "We will no longer allow accounts to enroll in the text message/SMS method of 2FA unless they are Twitter Blue subscribers." Twitter users who have not subscribed to Blue that have enrolled for SMS-based 2FA have time till March 20, 2023, to switch to an alternative method such as an authenticator app or a hardware security key. After this cutoff date, non-Twitter Blue subscribers will have their option disabled. The alternative methods "require you to have physical possession of the authentication method and are a great way to ensure your account is secure," Twitter noted. Given that SMS has been the  least secure form of 2FA , the latest enforcement is likely to force people

GoDaddy Discloses Multi-Year Security Breach Causing Malware Installations and Source Code Theft

GoDaddy Discloses Multi-Year Security Breach Causing Malware Installations and Source Code Theft

Feb 18, 2023 Server Security / Malware
Web hosting services provider GoDaddy on Friday disclosed a multi-year security breach that enabled unknown threat actors to install malware and siphon source code related to some of its services. The company attributed the campaign to a "sophisticated and organized group targeting hosting services." GoDaddy said in December 2022, it received an unspecified number of customer complaints about their websites getting sporadically redirected to malicious sites, which it later found was due to the unauthorized third party gaining access to servers hosted in its  cPanel environment . The threat actor "installed malware causing the intermittent redirection of customer websites," the company  said . The ultimate objective of the intrusions, GoDaddy said, is to "infect websites and servers with malware for phishing campaigns, malware distribution, and other malicious activities." In a related 10-K filing with the U.S. Securities and Exchange Commission (SEC

Experts Warn of RambleOn Android Malware Targeting South Korean Journalists

Feb 17, 2023 Mobile Security / Cyber Threat
Suspected North Korean nation-state actors targeted a journalist in South Korea with a malware-laced Android app as part of a social engineering campaign. The findings come from South Korea-based non-profit Interlab, which coined the new malware  RambleOn . The malicious functionalities include the "ability to read and leak target's contact list, SMS, voice call content, location and others from the time of compromise on the target," Interlab threat researcher Ovi Liber  said  in a report published this week. The spyware camouflages as a secure chat app called Fizzle ( ch.seme ), but in reality, acts as a conduit to deliver a next-stage payload hosted on pCloud and Yandex. The chat app is said to have been sent as an Android Package (APK) file over WeChat to the targeted journalist on December 7, 2022, under the pretext of wanting to discuss a sensitive topic. The primary purpose of RambleOn is to function as a loader for another APK file ( com.data.WeCoin ) while

Armenian Entities Hit by New Version of OxtaRAT Spying Tool

Feb 17, 2023 Cyber Threat / Surveillanceware
Entities in Armenia have come under a cyber attack using an updated version of a backdoor called  OxtaRAT  that allows remote access and desktop surveillance. "The tool capabilities include searching for and exfiltrating files from the infected machine, recording the video from the web camera and desktop, remotely controlling the compromised machine with TightVNC, installing a web shell, performing port scanning, and more," Check Point Research  said  in a report. The latest campaign is said to have commenced in November 2022 and marks the first time the threat actors behind the activity have expanded their focus beyond Azerbaijan. "The threat actors behind these attacks have been targeting human rights organizations, dissidents, and independent media in Azerbaijan for several years," the cybersecurity firm noted, calling the campaign Operation Silent Watch. The late 2022 intrusions are significant, not least because of the changes in the infection chain, the s

New Mirai Botnet Variant 'V3G4' Exploiting 13 Flaws to Target Linux and IoT Devices

Feb 17, 2023 IoT Security / Cyber Attack
A new variant of the notorious Mirai botnet has been found leveraging several security vulnerabilities to propagate itself to Linux and IoT devices. Observed during the second half of 2022, the new version has been dubbed  V3G4  by Palo Alto Networks Unit 42, which identified three different campaigns likely conducted by the same threat actor. "Once the vulnerable devices are compromised, they will be fully controlled by attackers and become a part of the botnet," Unit 42 researchers  said . "The threat actor has the capability to utilize those devices to conduct further attacks, such as distributed denial-of-service (DDoS) attacks." The attacks primarily single out exposed servers and networking devices running Linux, with the adversary weaponizing as many as 13 flaws that could lead to remote code execution (RCE). Some of the notable flaws relate to critical flaws in Atlassian Confluence Server and Data Center, DrayTek Vigor routers, Airspan AirSpot, and Geu

Critical RCE Vulnerability Discovered in ClamAV Open Source Antivirus Software

Feb 17, 2023 Sysadmin / Endpoint Security
Cisco has rolled out security updates to address a critical flaw reported in the ClamAV open source antivirus engine that could lead to remote code execution on susceptible devices. Tracked as  CVE-2023-20032  (CVSS score: 9.8), the issue relates to a case of remote code execution residing in the HFS+ file parser component. The flaw affects versions 1.0.0 and earlier, 0.105.1 and earlier, and 0.103.7 and earlier. Google security engineer Simon Scannell has been credited with discovering and reporting the bug. "This vulnerability is due to a missing buffer size check that may result in a heap buffer overflow write," Cisco Talos  said  in an advisory. "An attacker could exploit this vulnerability by submitting a crafted HFS+ partition file to be scanned by ClamAV on an affected device." Successful exploitation of the weakness could enable an adversary to run arbitrary code with the same privileges as that of the ClamAV scanning process, or crash the process, resu
