New Lenovo UEFI Firmware Vulnerabilities Affect Millions of Laptops

New Lenovo UEFI Firmware Vulnerabilities Affect Millions of Laptops

April 19, 2022Ravie Lakshmanan
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 Disrupts ZLoader Cybercrime Botnet in Global Operation

Microsoft Disrupts ZLoader Cybercrime Botnet in Global Operation

April 14, 2022Ravie Lakshmanan
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.

Russian Hackers Tried Attacking Ukraine's Power Grid with Industroyer2 Malware

April 13, 2022Ravie Lakshmanan
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

Hackers Distributing Fake Shopping Apps to Steal Banking Data of Malaysian Users

April 06, 2022Ravie Lakshmanan
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

Experts Detail Virtual Machine Used by Wslink Malware Loader for Obfuscation

March 29, 2022Ravie Lakshmanan
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
Chinese 'Mustang Panda' Hackers Spotted Deploying New 'Hodur' Malware

Chinese 'Mustang Panda' Hackers Spotted Deploying New 'Hodur' Malware

March 23, 2022Ravie Lakshmanan
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

Antivirus firm ESET and BitDefender website Hijacked by Pro-Palestinian Hackers

October 12, 2013Mohit Kumar
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
