The North Korea-backed Lazarus Group has been observed deploying a Windows rootkit by taking advantage of an exploit in a Dell firmware driver, highlighting new tactics adopted by the state-sponsored adversary. The Bring Your Own Vulnerable Driver ( BYOVD ) attack, which took place in the autumn of 2021, is another variant of the threat actor's espionage-oriented activity called Operation In(ter)ception  that's directed against aerospace and defense industries. "The campaign started with spear-phishing emails containing malicious Amazon-themed documents and targeted an employee of an aerospace company in the Netherlands, and a political journalist in Belgium," ESET researcher Peter Kálnai  said . Attack chains unfolded upon the opening of the lure documents, leading to the distribution of malicious droppers that were trojanized versions of open source projects, corroborating recent reports from Google's  Mandiant  and  Microsoft . ESET said it uncovered evid

A Linux variant of a backdoor known as SideWalk was used to target a Hong Kong university in February 2021, underscoring the cross-platform abilities of the implant.  Slovak cybersecurity firm ESET, which detected the malware in the university's network, attributed the backdoor to a nation-state actor dubbed  SparklingGoblin . The unnamed university is said to have been already targeted by the group in May 2020 during the  student protests . "The group continuously targeted this organization over a long period of time, successfully compromising multiple key servers, including a print server, an email server, and a server used to manage student schedules and course registrations," ESET  said  in a report shared with The Hacker News. SparklingGoblin is the name given to a Chinese advanced persistent threat (APT) group with connections to the  Winnti umbrella  (aka APT41, Barium, Earth Baku, or Wicked Panda). It's primarily known for its attacks targeting various en

It comes as no surprise that today's cyber threats are orders of magnitude more complex than those of the past. And the ever-evolving tactics that attackers use demand the adoption of better, more holistic and consolidated ways to meet this non-stop challenge. Security teams constantly look for ways to reduce risk while improving security posture, but many approaches offer piecemeal solutions – zeroing in on one particular element of the evolving threat landscape challenge – missing the forest for the trees.  In the last few years, Exposure Management has become known as a comprehensive way of reigning in the chaos, giving organizations a true fighting chance to reduce risk and improve posture. In this article I'll cover what Exposure Management is, how it stacks up against some alternative approaches and why building an Exposure Management program should be on  your 2024 to-do list. What is Exposure Management?  Exposure Management is the systematic identification, evaluation,

The North Korea-backed Lazarus Group has been observed targeting job seekers with malware capable of executing on Apple Macs with Intel and M1 chipsets. Slovak cybersecurity firm ESET linked it to a campaign dubbed " Operation In(ter)ception " that was first disclosed in June 2020 and involved using social engineering tactics to trick employees working in the aerospace and military sectors into opening decoy job offer documents. The latest attack is no different in that a job description for the Coinbase cryptocurrency exchange platform was used as a launchpad to drop a signed Mach-O executable. ESET's analysis comes from a sample of the binary that was uploaded to VirusTotal from Brazil on August 11, 2022. "Malware is compiled for both Intel and Apple Silicon," the company  said  in a series of tweets. "It drops three files: a decoy PDF document ' Coinbase_online_careers_2022_07.pdf ', a bundle  'FinderFontsUpdater.app ,' and a downloa

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 intent of its operators is to gather information from the victims' Macs by exfiltrating documents, keystrokes, and screen captures," ESET researcher Marc-Etienne M.Léveillé  said  in a report published today. CloudMensis, written in Objective-C, was first discovered in April 2022 and is designed to strike both Intel and Apple silicon architectures. The initial infection vector for the attacks and the targets remain unknown as yet. But its very limited distribution is an indication that the malware is being used as part of a highly targeted operation directed against entities of i

Three high-impact Unified Extensible Firmware Interface (UEFI) security vulnerabilities have been discovered impacting various Lenovo consumer laptop models, enabling malicious actors to deploy and execute firmware implants on the affected devices. Tracked as CVE-2021-3970, CVE-2021-3971, and CVE-2021-3972, the latter two "affect firmware drivers originally meant to be used only during the manufacturing process of Lenovo consumer notebooks," ESET researcher Martin Smolár  said  in a report published today. "Unfortunately, they were mistakenly included also in the production BIOS images without being properly deactivated," Smolár added. Successful exploitation of the flaws could permit an attacker to disable SPI flash protections or Secure Boot, effectively granting the adversary the ability to install persistent malware that can survive system reboots. CVE-2021-3970, on the other hand, relates to a case of memory corruption in the System Management Mode ( SMM

Microsoft and a consortium of cybersecurity companies took legal and technical steps to disrupt the ZLoader botnet , seizing control of 65 domains that were used to control and communicate with the infected hosts. "ZLoader is made up of computing devices in businesses, hospitals, schools, and homes around the world and is run by a global internet-based organized crime gang operating malware as a service that is designed to steal and extort money," Amy Hogan-Burney, general manager of Microsoft's Digital Crimes Unit (DCU),  said . The operation, Microsoft said, was undertaken in collaboration with ESET, Lumen's Black Lotus Labs, Palo Alto Networks Unit 42, Avast, Financial Services Information Sharing and Analysis Center (FS-ISAC), and Health Information Sharing and Analysis Center (H-ISAC). As a result of the disruption, the domains are now redirected to a sinkhole, effectively preventing the botnet's criminal operators from contacting the compromised devices.

The Computer Emergency Response Team of Ukraine (CERT-UA) on Tuesday  disclosed  that it thwarted a cyberattack by Sandworm , a hacking group affiliated with Russia's military intelligence, to sabotage the operations of an unnamed energy provider in the country. "The attackers attempted to take down several infrastructure components of their target, namely: Electrical substations, Windows-operated computing systems, Linux-operated server equipment, [and] active network equipment," the State Service of Special Communications and Information Protection of Ukraine (SSSCIP)  said  in a statement. Slovak cybersecurity firm ESET, which collaborated with CERT-UA to analyze the attack, said the attempted intrusion involved the use of ICS-capable malware and regular disk wipers, with the adversary unleashing an updated variant of the  Industroyer  malware, which was first deployed in a 2016 assault on Ukraine's power grid. "The Sandworm attackers made an attempt to d

Threat actors have been distributing malicious applications under the guise of seemingly harmless shopping apps to target customers of eight Malaysian banks since at least November 2021. The attacks involved setting up fraudulent but legitimate-looking websites to trick users into downloading the apps, Slovak cybersecurity firm ESET said in a report shared with The Hacker News. The copycat websites impersonated cleaning services such as Maid4u, Grabmaid, Maria's Cleaning, Maid4u, YourMaid, Maideasy and MaidACall and a pet store named PetsMore, all of which are aimed at users in Malaysia. "The threat actors use these fake e-shop applications to phish for banking credentials," ESET  said . "The apps also forward all SMS messages received by the victim to the malware operators in case they contain 2FA codes sent by the bank." The targeted banks include Maybank, Affin Bank, Public Bank Berhad, CIMB bank, BSN, RHB, Bank Islam Malaysia, and Hong Leong Bank. Th

Cybersecurity researchers have shed more light on a malicious loader that runs as a server and executes received modules in memory, laying bare the structure of an "advanced multi-layered virtual machine" used by the malware to fly under the radar. Wslink, as the malicious loader is called, was first  documented  by Slovak cybersecurity company ESET in October 2021, with very few telemetry hits detected in the past two years spanning Central Europe, North America, and the Middle East. Analysis of the malware samples have yielded little to no clues about the initial compromise vector used, and no code, functionality, or operational similarities have been uncovered to suggest that this is a tool from a previously identified threat actor. Packed with a file compression utility named NsPack, Wslink makes use of what's called a  process virtual machine  (VM), a mechanism to run an application in a platform-independent manner that abstracts the underlying hardware or opera

A China-based advanced persistent threat (APT) known as Mustang Panda has been linked to an ongoing cyber espionage campaign using a previously undocumented variant of the  PlugX  remote access trojan on infected machines. Slovak cybersecurity firm ESET dubbed the new version Hodur , owing to its resemblance to another PlugX (aka Korplug) variant called  THOR  that came to light in July 2021. "Most victims are located in East and Southeast Asia, but a few are in Europe (Greece, Cyprus, Russia) and Africa (South Africa, South Sudan)," ESET malware researcher Alexandre Côté Cyr  said  in a report shared with The Hacker News. "Known victims include research entities, internet service providers (ISPs), and European diplomatic missions mostly located in East and Southeast Asia." Mustang Panda, also known as TA416, HoneyMyte, RedDelta, or PKPLUG, is a  cyber espionage group  that's primarily known for targeting non-governmental organizations with a specific foc

A pro-Palestinian hacktivist group ' KDMS Team ', who recently managed to briefly hijack the Metasploit website of security firm Rapid7 and become popular after Hacking World's largest Web Hosting Network Leaseweb website and antivirus vendors AVG, Avira as well as mobile messaging service WhatsApp's websites. Now even I have to say that - Security is just an Illusion, because just now the group aligned with Anonymous has successfully hijacked another two Antivirus firm website - ESET and Bitdefender . The KDMS Team successfully changed the DNS records of both sites to redirect people to a website playing the Palestinian national anthem and displaying a political message under the title " You Got Pwned ". Message posted on Bitdefender and Eset website says: Hello bitdefender Touched By KDMS team We was thinking about quitting hacking and disappear again ..! But we said : there is some sites must be hacked You are one of our targe
