Brazilian Cybercriminals Using LOLBaS and CMD Scripts to Drain Bank Accounts

Brazilian Cybercriminals Using LOLBaS and CMD Scripts to Drain Bank Accounts

Jun 05, 2023 Banking Security / Malware
An unknown cybercrime threat actor has been observed targeting Spanish- and Portuguese-speaking victims to compromise online banking accounts in Mexico, Peru, and Portugal. "This threat actor employs tactics such as LOLBaS (living-off-the-land binaries and scripts), along with CMD-based scripts to carry out its malicious activities," the BlackBerry Research and Intelligence Team  said  in a report published last week. The cybersecurity company attributed the campaign, dubbed Operation CMDStealer , to a Brazilian threat actor based on an analysis of the artifacts. The attack chain primarily leverages social engineering, banking on Portuguese and Spanish emails containing tax- or traffic violation-themed lures to trigger the infections and gain unauthorized access to victims' systems. The emails come fitted with an HTML attachment that contains obfuscated code to fetch the next-stage payload from a remote server in the form of a RAR archive file. The files, which are

Alert: Brazilian Hackers Targeting Users of Over 30 Portuguese Banks

May 25, 2023 Financial Security / Cyber Threat
A Brazilian threat actor is targeting more than 30 Portuguese financial institutions with information-stealing malware as part of a long-running campaign that commenced in 2021. "The attackers can steal credentials and exfiltrate users' data and personal information, which can be leveraged for malicious activities beyond financial gain," SentinelOne researchers Aleksandar Milenkoski and Tom Hegel  said  in a new report shared with The Hacker News. The cybersecurity firm, which began tracking "Operation Magalenha" earlier this year, said the intrusions culminate in the deployment of two variants of a backdoor called  PeepingTitle  so as to "maximize attack potency." The links to Brazil stem from the use of the Brazilian-Portuguese language within the detected artifacts as well as source code overlaps with another banking trojan known as  Maxtrilha , which was first disclosed in September 2021. PeepingTitle, like Maxtrilha, is written in the Delphi
SaaS Compliance through the NIST Cybersecurity Framework

SaaS Compliance through the NIST Cybersecurity Framework

Feb 20, 2024Cybersecurity Framework / SaaS Security
The US National Institute of Standards and Technology (NIST) cybersecurity framework is one of the world's most important guidelines for securing networks. It can be applied to any number of applications, including SaaS.  One of the challenges facing those tasked with securing SaaS applications is the different settings found in each application. It makes it difficult to develop a configuration policy that will apply to an HR app that manages employees, a marketing app that manages content, and an R&D app that manages software versions, all while aligning with NIST compliance standards.  However, there are several settings that can be applied to nearly every app in the SaaS stack. In this article, we'll explore some universal configurations, explain why they are important, and guide you in setting them in a way that improves your SaaS apps' security posture.  Start with Admins Role-based access control (RBAC) is a key to NIST adherence and should be applied to every SaaS a

PixPirate: New Android Banking Trojan Targeting Brazilian Financial Institutions

Feb 04, 2023 Mobile Security / Malware
A new Android banking trojan has set its eyes on Brazilian financial institutions to commit fraud by leveraging the PIX payments platform. Italian cybersecurity company Cleafy, which discovered the malware between the end of 2022 and the beginning of 2023, is tracking it under the name PixPirate. "PixPirate belongs to the newest generation of Android banking trojan, as it can perform ATS ( Automatic Transfer System ), enabling attackers to automate the insertion of a malicious money transfer over the instant payment platform PIX, adopted by multiple Brazilian banks," researchers Francesco Iubatti and Alessandro Strino  said . It is also the latest addition in a long list of Android banking malware to abuse the operating system's accessibility services API to carry out its nefarious functions, including disabling Google Play Protect, intercepting SMS messages, preventing uninstallation, and serving rogue ads via push notifications. Besides stealing passwords entered

More Stealthier Version of BrazKing Android Malware Spotted in the Wild

More Stealthier Version of BrazKing Android Malware Spotted in the Wild

Nov 23, 2021
Banking apps from Brazil are being targeted by a more elusive and stealthier version of an Android remote access trojan (RAT) that's capable of carrying out financial fraud attacks by stealing two-factor authentication (2FA) codes and initiating rogue transactions from infected devices to transfer money from victims' accounts to an account operated by the threat actor. IBM X-Force dubbed the revamped banking malware BrazKing , a previous version of which was referred to as  PixStealer  by Check Point Research. The mobile RAT was first seen around November 2018,  according  to ThreatFabric. "It turns out that its developers have been working on making the malware more agile than before, moving its core overlay mechanism to pull fake overlay screens from the command-and-control (C2) server in real-time," IBM X-Force researcher Shahar Tavor  noted  in a technical deep dive published last week. "The malware […] allows the attacker to log keystrokes, extract the pa

Hackers Targeting Brazil's PIX Payment System to Drain Users' Bank Accounts

Sep 29, 2021
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
