Two newly discovered malicious Android applications on Google Play Store have been used to target users of Brazil's instant payment ecosystem in a likely attempt to lure victims into fraudulently transferring their entire account balances into another bank account under cybercriminals' control. "The attackers distributed two different variants of banking malware, named PixStealer and MalRhino , through two separate malicious applications […] to carry out their attacks," Check Point Research said in an analysis shared with The Hacker News. "Both malicious applications were designed to steal money of victims through user interaction and the original PIX application." The two apps in question, which were uncovered in April 2021, have since been removed from the app store. Launched in November 2020 by the Central Bank of Brazil, the country's monetary authority,  Pix  is a state-owned payments platform that enables consumers and companies to make mone...

Commercially developed FinFisher surveillanceware has been upgraded to infect Windows devices using a  UEFI  (Unified Extensible Firmware Interface) bootkit that leverages a trojanized Windows Boot Manager, marking a shift in infection vectors that allow it to elude discovery and analysis. Detected in the wild since 2011, FinFisher (aka FinSpy or Wingbird) is a spyware toolset for Windows, macOS, and Linux developed by Anglo-German firm Gamma International and supplied exclusively to law enforcement and intelligence agencies. But like with NSO Group's Pegasus, the software has also been used to  spy on Bahraini activists  in the past allegedly and delivered as part of  spear-phishing campaigns  in September 2017. FinFisher is equipped to harvest user credentials, file listings, sensitive documents, record keystrokes, siphon email messages from Thunderbird, Outlook, Apple Mail, and Icedove, intercept Skype contacts, chats, calls and transferred files, an...

Opportunistic threat actors have been found actively exploiting a recently disclosed critical security flaw in Atlassian Confluence deployments across Windows and Linux to deploy web shells that result in the execution of crypto miners on compromised systems. Tracked as  CVE-2021-26084  (CVSS score: 9.8), the vulnerability concerns an OGNL (Object-Graph Navigation Language) injection flaw that could be exploited to achieve arbitrary code execution on a Confluence Server or Data Center instance. "A remote attacker can exploit this vulnerability by sending a crafted HTTP request containing a malicious parameter to a vulnerable server," researchers from Trend Micro  noted  in a technical write-up detailing the weakness. "Successful exploitation can result in arbitrary code execution in the security context of the affected server." The vulnerability, which resides in the Webwork module of Atlassian Confluence Server and Data Center, stems from an insufficient valid...

A new advanced trojan sold on Russian-speaking underground forums comes with capabilities to steal users' accounts on popular online video game distribution services, including Steam, Epic Games Store, and EA Origin, underscoring a growing threat to the lucrative gaming market. Cybersecurity firm Kaspersky, which coined the malware " BloodyStealer ," said it first detected the malicious tool in March 2021 as being advertised for sale at an attractive price of 700 RUB (less than $10) for one month or $40 for a lifetime subscription. Attacks using Bloody Stealer have been uncovered so far in Europe, Latin America, and the Asia-Pacific region. "BloodyStealer is a Trojan-stealer capable of gathering and exfiltrating various types of data, for cookies, passwords, forms, banking cards from browsers, screenshots, log-in memory, and sessions from various applications," the company  said . The information harvested from gaming apps, such as Bethesda, Epic Games, GOG,...

Microsoft on Monday revealed new malware deployed by the hacking group behind the SolarWinds supply chain attack last December to deliver additional payloads and steal sensitive information from Active Directory Federation Services ( AD FS ) servers. The tech giant's Threat Intelligence Center (MSTIC) codenamed the "passive and highly targeted backdoor" FoggyWeb, making it the threat actor tracked as Nobelium's latest tool in a long list of cyber weaponry such as  Sunburst ,  Sunspot ,  Raindrop ,  Teardrop ,  GoldMax, GoldFinder, Sibot ,  Flipflop ,  NativeZone ,  EnvyScout, BoomBox, and VaporRage . "Once Nobelium obtains credentials and successfully compromises a server, the actor relies on that access to maintain persistence and deepen its infiltration using sophisticated malware and tools," MSTIC researchers  said . "Nobelium uses FoggyWeb to remotely exfiltrate the configuration database of compromised AD FS servers, decrypted token-...

State-sponsored hackers affiliated with Russia are behind a new series of intrusions using a previously undocumented implant to compromise systems in the U.S., Germany, and Afghanistan. Cisco Talos attributed the attacks to the  Turla  advanced persistent threat (APT) group, coining the malware "TinyTurla" for its limited functionality and efficient coding style that allows it to go undetected. Attacks incorporating the backdoor are believed to have occurred since 2020. "This simple backdoor is likely used as a second-chance backdoor to maintain access to the system, even if the primary malware is removed," the researchers  said . "It could also be used as a second-stage dropper to infect the system with additional malware." Furthermore, TinyTurla can upload and execute files or exfiltrate sensitive data from the infected machine to a remote server, while also polling the command-and-control (C2) station every five seconds for any new commands. Also k...

The operators behind the BlackRock mobile malware have surfaced back with a new Android banking trojan called  ERMAC  that targets Poland and has its roots in the infamous Cerberus malware, according to the latest research. "The new trojan already has active distribution campaigns and is targeting 378 banking and wallet apps with overlays," ThreatFabric's CEO Cengiz Han Sahin said in an emailed statement. First campaigns involving ERMAC are believed to have begun in late August under the guise of the Google Chrome app. Since then, the attacks have expanded to include a range of apps such as banking, media players, delivery services, government applications, and antivirus solutions like  McAfee . Almost fully based on the notorious banking trojan  Cerberus , the Dutch cybersecurity firm's findings come from forum posts made by an actor named DukeEugene last month on August 17, inviting prospective customers to "rent a new android botnet with wide functionalit...
