The MITRE Corporation has officially made available a new threat-modeling framework called  EMB3D  for makers of embedded devices used in critical infrastructure environments. "The model provides a cultivated knowledge base of cyber threats to embedded devices, providing a common understanding of these threats with the security mechanisms required to mitigate them," the non-profit said in a post announcing the move. A draft version of the model, which has been conceived in collaboration with Niyo 'Little Thunder' Pearson, Red Balloon Security, and Narf Industries, was  previously released  on December 13, 2023. EMB3D, like the  ATT&CK framework , is expected to be a "living framework," with new and mitigations added and updated over time as new actors, vulnerabilities, and attack vectors emerge, but with a specific focus on embedded devices. The ultimate goal is to provide device vendors with a unified picture of different vulnerabilities in t

With the browser becoming the most prevalent workspace in the enterprise, it is also turning into a popular attack vector for cyber attackers. From account takeovers to malicious extensions to phishing attacks, the browser is a means for stealing sensitive data and accessing organizational systems. Security leaders who are planning their security architecture require data and insights into the browser threat landscape. Recently, LayerX released the " Annual Browser Security Report 2024 ", providing an in-depth analysis of the evolving threat landscape for browser security.  This comprehensive report highlights the critical vulnerabilities and attack vectors that pose the greatest risks to enterprise security. It allows decision-makers and stakeholders to benchmark the security challenges of their environment so they can make actionable decisions. Below, we detail key findings from the report and a summarized list of security recommendations. We urge you to read the entire  report ,

In the last decade, there has been a growing disconnect between front-line analysts and senior management in IT and Cybersecurity. Well-documented challenges facing modern analysts revolve around a high volume of alerts, false positives, poor visibility of technical environments, and analysts spending too much time on manual tasks. The Impact of Alert Fatigue and False Positives  Analysts are overwhelmed with alerts. The knock-on effect of this is that fatigued analysts are at risk of missing key details in incidents, and often conduct time-consuming triaging tasks manually only to end up copying and pasting a generic closing comment into a false positive alert.  It is likely that there will always be false positives. And many would argue that a false positive is better than a false negative. But for proactive actions to be made, we must move closer to the heart of an incident. That requires diving into how analysts conduct the triage and investigation process. SHQ Response Platfo

Cybersecurity researchers have disclosed multiple security flaws in Cinterion cellular modems that could be potentially exploited by threat actors to access sensitive information and achieve code execution. "These vulnerabilities include critical flaws that permit remote code execution and unauthorized privilege escalation, posing substantial risks to integral communication networks and IoT devices foundational to industrial, healthcare, automotive, financial and telecommunications sectors," Kaspersky  said . Cinterion modems were originally developed by Gemalto before the business was  acquired  by Telit from Thales as part of a deal announced in July 2022. The findings were  presented  at the OffensiveCon held in Berlin on May 11. The list of eight flaws is as follows - CVE-2023-47610  (CVSS score: 8.1) - A buffer overflow vulnerability that could allow a remote unauthenticated attacker to execute arbitrary code on the targeted system by sending a specially crafted S

The Black Basta ransomware-as-a-service (RaaS) operation has targeted more than 500 private industry and critical infrastructure entities in North America, Europe, and Australia since its emergence in April 2022. In a joint advisory published by the Cybersecurity and Infrastructure Security Agency (CISA), the Federal Bureau of Investigation (FBI), the Department of Health and Human Services (HHS), and the Multi-State Information Sharing and Analysis Center (MS-ISAC), the agencies said the threat actors encrypted and stole data from at least 12 out of 16 critical infrastructure sectors. "Black Basta affiliates use common initial access techniques — such as phishing and exploiting known vulnerabilities — and then employ a double-extortion model, both encrypting systems and exfiltrating data," the bulletin  read . Unlike other ransomware groups, the ransom notes dropped at the end of the attack do not contain an initial ransom demand or payment instructions. Rather, the note

Cybersecurity researchers have identified a malicious Python package that purports to be an offshoot of the  popular requests library  and has been found concealing a Golang-version of the Sliver command-and-control (C2) framework within a PNG image of the project's logo.  The package employing this steganographic trickery is  requests-darwin-lite , which has been downloaded 417 times prior to it being taken down from the Python Package Index (PyPI) registry. Requests-darwin-lite "appeared to be a fork of the ever-popular requests package with a few key differences, most notably the inclusion of a malicious Go binary packed into a large version of the actual requests side-bar PNG logo," software supply chain security firm Phylum  said . The changes have been introduced in the package's setup.py file, which has been configured to decode and execute a Base64-encoded command to gather the system's Universally Unique Identifier ( UUID ). In what's an interes

The financially motivated threat actor known as  FIN7  has been observed leveraging malicious Google ads spoofing legitimate brands as a means to deliver MSIX installers that culminate in the deployment of  NetSupport RAT . "The threat actors used malicious websites to impersonate well-known brands, including AnyDesk, WinSCP, BlackRock, Asana, Concur, The Wall Street Journal, Workable, and Google Meet," cybersecurity firm eSentire  said  in a report published earlier this week. FIN7 (aka Carbon Spider and Sangria Tempest) is a  persistent e-crime group  that's been active since 2013, initially dabbling in attacks targeting point-of-sale (PoS) devices to steal payment data, before pivoting to breaching large firms via ransomware campaigns. Over the years, the threat actor has refined its tactics and malware arsenal, adopting  various   custom malware  families such as BIRDWATCH, Carbanak, DICELOADER (aka Lizar and Tirion), POWERPLANT, POWERTRASH, and TERMITE, among ot

SaaS applications are dominating the corporate landscape. Their increased use enables organizations to push the boundaries of technology and business. At the same time, these applications also pose a new security risk that security leaders need to address, since the existing security stack does not enable complete control or comprehensive monitoring of their usage. LayerX has recently released a new guide, " Let There Be Light: Eliminating the Risk of Shadow SaaS " for security and IT teams, which addresses this gap. The guide explains the challenges of shadow SaaS, i.e., the use of unauthorized SaaS apps for work purposes, and suggests practices and controls that can mitigate them. The guide also compares various security controls that attempt to address this risk (CASB, SASE, Secure Browser Extension) and explains how each one operates and its efficacy. Consequently, the guide is a must-read for all security leaders at modern organizations. Here are the main highlights:

The North Korean threat actor tracked as Kimsuky has been observed deploying a previously undocumented Golang-based malware dubbed  Durian  as part of highly-targeted cyber attacks aimed at two South Korean cryptocurrency firms. "Durian boasts comprehensive backdoor functionality, enabling the execution of delivered commands, additional file downloads, and exfiltration of files," Kaspersky  said  in its APT trends report for Q1 2024. The attacks, which occurred in August and November 2023, entailed the use of legitimate software exclusive to South Korea as an infection pathway, although the precise mechanism used to manipulate the program is currently unclear. What's known is that the software establishes a connection to the attacker's server, leading to the retrieval of a malicious payload that kicks off the infection sequence. The first-stage serves as an installer for additional malware and a means to establish persistence on the host. It also paves the way fo

Google on Thursday released security updates to address a zero-day flaw in Chrome that it said has been actively exploited in the wild. Tracked as  CVE-2024-4671 , the high-severity vulnerability has been described as a case of use-after-free in the Visuals component. It was reported by an anonymous researcher on May 7, 2024. Use-after-free bugs , which arise when a program references a memory location after it has been deallocated, can lead to any number of consequences, ranging from a crash to arbitrary code execution. "Google is aware that an exploit for CVE-2024-4671 exists in the wild," the company  said  in a terse advisory without revealing additional specifics of how the flaw is being weaponized in real-world attacks or the identity of the threat actors behind them. With the latest development, Google has addressed two actively exploited zero-days in Chrome since the start of the year. Earlier this January, the tech giant patched an out-of-bounds memory access
