An Iranian government-backed actor known as  Mint Sandstorm  has been linked to attacks aimed at critical infrastructure in the U.S. between late 2021 to mid-2022. "This Mint Sandstorm subgroup is technically and operationally mature, capable of developing bespoke tooling and quickly weaponizing N-day vulnerabilities, and has demonstrated agility in its operational focus, which appears to align with Iran's national priorities," the Microsoft Threat Intelligence team  said  in an analysis. Targeted entities consist of seaports, energy companies, transit systems, and a major U.S. utility and gas company. The activity is suspected to be retaliatory and in response to attacks targeting its maritime,  railway , and  gas station payment systems  that took place between May 2020 and late 2021. It's worth noting here that Iran subsequently  accused  Israel and the U.S. of masterminding the attacks on the gas stations in a bid to create unrest in ...

A fresh round of patches has been made available for the vm2 JavaScript library to address two critical flaws that could be exploited to break out of sandbox protections and achieve code execution. Both the flaws –  CVE-2023-29199  and  CVE-2023-30547  – are rated 9.8 out of 10 on the CVSS scoring system and have been addressed in versions 3.9.16 and 3.9.17, respectively. Successful  exploitation  of the  bugs , which allow an attacker to raise an unsanitized host exception, could be weaponized to escape the sandbox and run arbitrary code in the host context. "A threat actor can bypass the sandbox protections to gain remote code execution rights on the host running the sandbox," the maintainers of the vm2 library said in an alert. Credited with discovering and reporting the vulnerabilities is security researcher  SeungHyun Lee , who has also  released   proof-of-concept  (PoC) exploits for the two issues in question. The disc...

Cybersecurity researchers have detailed the inner workings of a highly evasive loader named " in2al5d p3in4er " (read: invalid printer) that's used to deliver the Aurora information stealer malware. "The in2al5d p3in4er loader is compiled with  Embarcadero RAD Studio  and targets endpoint workstations using advanced anti-VM (virtual machine) technique," cybersecurity firm Morphisec  said  in a report shared with The Hacker News. Aurora  is a Go-based information stealer that emerged on the threat landscape in late 2022. Offered as a commodity malware to other actors, it's distributed through  YouTube videos  and SEO-poised fake cracked software download websites. Clicking the links present in YouTube video descriptions redirects the victim to decoy websites where they are enticed into downloading the malware under the garb of a seemingly-legitimate utility. The loader analyzed by Morphisec is designed to query the vendor ID of the graphics card i...

A new Android malware strain named  Goldoson  has been detected in the official Google Play Store spanning more than 60 legitimate apps that collectively have over 100 million downloads. An additional eight million installations have been tracked through ONE store, a leading third-party app storefront in South Korea. The rogue component is part of a third-party software library used by the apps in question and is capable of gathering information about installed apps, Wi-Fi and Bluetooth-connected devices, and GPS locations. "Moreover, the library is armed with the functionality to perform ad fraud by clicking advertisements in the background without the user's consent," McAfee security researcher SangRyol Ryu  said  in a report published last week. What's more, it includes the ability to stealthily load web pages, a feature that could be abused to load ads for financial profit. It achieves this by loading HTML code in a hidden  WebView  and driving tr...

Rapid technological evolution requires security that is resilient, up to date and adaptable. In this article, we will cover the transformation in the field of DFIR (digital forensics and incident response) in the last couple years, focusing on the digital forensics' aspect and how XDR fits into the picture. Before we dive into the details, let's first break down the main components of DFIR and define the differences between them. Digital Forensics vs Incident Response Digital forensics:  the practice of using scientific techniques and tools to identify, preserve, and analyze digital evidence from various sources, such as computers, smartphones, and other electronic devices, in a way that is admissible in a court of law. Incident response:  the process of responding to and managing the aftermath of a security breach or cyberattack. This involves identifying the nature and scope of the incident, containing the damage, eradicating the threat, and restoring the affected sys...

The Iranian threat actor known as MuddyWater is continuing its time-tested tradition of relying on legitimate remote administration tools to commandeer targeted systems. While the nation-state group has previously employed  ScreenConnect, RemoteUtilities, and Syncro , a  new analysis  from Group-IB has revealed the adversary's use of the SimpleHelp remote support software in June 2022. MuddyWater, active since at least 2017, is assessed to be a subordinate element within Iran's Ministry of Intelligence and Security (MOIS). Some of the top targets include Turkey, Pakistan, the U.A.E., Iraq, Israel, Saudi Arabia, Jordan, the U.S., Azerbaijan, and Afghanistan. "MuddyWater uses SimpleHelp, a legitimate remote device control and management tool, to ensure persistence on victim devices," Nikita Rostovtsev, senior threat analyst at Group-IB, said. "SimpleHelp is not compromised and is used as intended. The threat actors found a way to download the tool from the of...

Threat actors behind the LockBit ransomware operation have developed new artifacts that can encrypt files on devices running Apple's macOS operating system. The development, which was  reported  by the MalwareHunterTeam over the weekend, appears to be the first time a big-game ransomware crew has created a macOS-based payload. Additional samples identified by  vx-underground  show that the macOS variant has been available since November 11, 2022, and has managed to evade detection by anti-malware engines until now. LockBit is a  prolific cybercrime crew  with ties to Russia that has been active since late 2019, with the threat actors releasing two major updates to the locker in 2021 and 2022. According to statistics  released by Malwarebytes  last week, LockBit emerged as the second most used ransomware in March 2023 after Cl0p, accounting for 93 successful attacks. An analysis of the new macOS version ("locker_Apple_M1_64") reveals that it...
