Hackers Target Real Estate Websites with Skimmer in Latest Supply Chain Attack

Hackers Target Real Estate Websites with Skimmer in Latest Supply Chain Attack

Jan 05, 2022
Threat actors leveraged a cloud video hosting service to carry out a supply chain attack on more than  100 real estate websites  operated by Sotheby's Realty that involved injecting malicious skimmers to steal sensitive personal information. "The attacker injected the skimmer JavaScript codes into video, so whenever others import the video, their websites get embedded with skimmer codes as well," Palo Alto Networks' Unit 42 researchers  said  in a report published this week. The skimmer attacks, also called formjacking, relates to a type of cyber attack wherein bad actors insert malicious JavaScript code into the target website, most often to checkout or payment pages on shopping and e-commerce portals, to harvest valuable information such as credit card details entered by users. In the latest incarnation of the Magecart attacks, the operators behind the campaign breached the Brightcove account of Sotheby's and deployed malicious code into the player of the ...
Microsoft Warns of Continued Attacks Exploiting Apache Log4j Vulnerabilities

Microsoft Warns of Continued Attacks Exploiting Apache Log4j Vulnerabilities

Jan 05, 2022
Microsoft is warning of continuing attempts by nation-state adversaries and commodity attackers to take advantage of  security vulnerabilities  uncovered in the Log4j open-source logging framework to deploy malware on vulnerable systems. "Exploitation attempts and testing have remained high during the last weeks of December," Microsoft Threat Intelligence Center (MSTIC)  said  in revised guidance published earlier this week. "We have observed many existing attackers adding exploits of these vulnerabilities in their existing malware kits and tactics, from coin miners to hands-on-keyboard attacks." Publicly disclosed by the Apache Software Foundation on December 10, 2021, the remote code execution (RCE) vulnerability in Apache Log4j 2, aka  Log4Shell , has emerged as a new attack vector for  widespread exploitation  by a variety of threat actors. In the subsequent weeks, four more weaknesses in the utility have come to light —  CVE-2021-45046 ,...
SAILFISH System to Find State-Inconsistency Bugs in Smart Contracts

SAILFISH System to Find State-Inconsistency Bugs in Smart Contracts

Jan 04, 2022
A group of academics from the University of California, Santa Barbara, has demonstrated what it calls a "scalable technique" to vet smart contracts and mitigate state-inconsistency bugs, discovering 47 zero-day vulnerabilities on the Ethereum blockchain in the process. Smart contracts are  programs  stored on the blockchain that are automatically executed when predetermined conditions are met based on the encoded terms of the agreement. They allow trusted transactions and agreements to be carried out between anonymous parties without the need for a central authority. In other words, the code itself is meant to be the final arbiter of "the deal" it represents, with the program controlling all aspects of the execution, and providing an immutable evidentiary audit trail of transactions that are both trackable and irreversible. This also means that vulnerabilities in the code could result in hefty losses, as evidenced by hacks aimed at  the DAO  and more recently,...

Researchers Detail New HomeKit 'doorLock' Bug Affecting Apple iOS

Researchers Detail New HomeKit 'doorLock' Bug Affecting Apple iOS

Jan 04, 2022
A persistent denial-of-service (DoS) vulnerability has been discovered in Apple's iOS mobile operating system that's capable of sending affected devices into a crash or reboot loop upon connecting to an Apple Home-compatible appliance. The behavior, dubbed "doorLock," is trivial in that it can be triggered by simply changing the name of a HomeKit device to a string larger than 500,000 characters. This causes an iPhone or iPad that attempts to connect to the device to become unresponsive and enter an indefinite cycle of system failure and restart that can only be mitigated by restoring the affected device from Recovery or DFU (Device Firmware Update) Mode. HomeKit  is Apple's software framework that allows iOS and iPadOS users to configure, communicate with, and control connected accessories and smart-home appliances using Apple devices. "Any device with an affected iOS version installed that loads the string will be disrupted, even after rebooting,...
Beware of Fake Telegram Messenger App Hacking PCs with Purple Fox Malware

Beware of Fake Telegram Messenger App Hacking PCs with Purple Fox Malware

Jan 04, 2022
Trojanized installers of the Telegram messaging application are being used to distribute the Windows-based Purple Fox backdoor on compromised systems. That's according to new research published by Minerva Labs, describing the attack as different from intrusions that typically take advantage of legitimate software for dropping malicious payloads. "This threat actor was able to leave most parts of the attack under the radar by separating the attack into several small files, most of which had very low detection rates by [antivirus] engines, with the final stage leading to Purple Fox rootkit infection," researcher Natalie Zargarov  said . First discovered in 2018, Purple Fox comes with rootkit capabilities that allow the malware to be planted beyond the reach of security solutions and evade detection. A March 2021 report from Guardicore  detailed  its worm-like propagation feature, enabling the backdoor to spread more rapidly. Then in October 2021, Trend Micro researche...
Detecting Evasive Malware on IoT Devices Using Electromagnetic Emanations

Detecting Evasive Malware on IoT Devices Using Electromagnetic Emanations

Jan 03, 2022
Cybersecurity researchers have proposed a novel approach that harnesses electromagnetic field emanations from the Internet of Things (IoT) devices as a side-channel to glean precise knowledge about the different kinds of malware targeting the embedded systems, even in scenarios where obfuscation techniques have been applied to hinder analysis. With the rapid adoption of IoT appliances presenting an attractive attack surface for threat actors, in part due to them being equipped with higher processing power and capable of running fully functional operating systems, the latest research aims to improve malware analysis to mitigate potential security risks. The findings were presented by a group of academics from the Research Institute of Computer Science and Random Systems (IRISA) at the Annual Computer Security Applications Conference ( ACSAC ) held last month. "[Electromagnetic] emanation that is measured from the device is practically undetectable by the malware," the res...
Are Medical Devices at Risk of Ransomware Attacks?

Are Medical Devices at Risk of Ransomware Attacks?

Jan 03, 2022
In May 2017, the first documented ransomware assault on networked medical equipment happened. The worldwide ransomware assault WannaCry compromised radiological and other instruments in several hospitals during its height, after a software failure caused by a cyberattack on its third-party vendor's oncology cloud service, cancer patients having radiation therapy at four healthcare institutions had to reschedule appointments. These examples show how cyberattacks and data breaches may have a significant impact on the healthcare industry, heavily reliant on connected medical equipment. PHI (patient health information) captured and stored in these connected medical devices must be secured. Because PHI is transferred over the cloud via server-based systems, making it very susceptible to hackers. Ransomware attacks on health care professionals have become more common, sophisticated, and severe in recent years. Individual bad actors have been supplanted as the main perpetrators by orga...
Microsoft Issues Fix for Exchange Y2K22 Bug That Crippled Email Delivery Service

Microsoft Issues Fix for Exchange Y2K22 Bug That Crippled Email Delivery Service

Jan 03, 2022
Microsoft, over the weekend, rolled out a fix to address an issue that caused email messages to get stuck on its Exchange Server platforms due to what it blamed on a date validation error at around the turn of the year. "The problem relates to a date check failure with the change of the new year and it [is] not a failure of the [antivirus] engine itself," the company  said  in a blog post. "This is not an issue with malware scanning or the malware engine, and it is not a security-related issue. The version checking performed against the signature file is causing the malware engine to crash, resulting in messages being stuck in transport queues." The Windows maker said the issue impacted on-premises versions of Exchange Server 2016 and Exchange Server 2019 but didn't specify how widespread the impact was. The issue began to  gain   attention  as the year 2022 kicked in, causing the servers to no longer deliver email messages while throwing the following erro...
New iLOBleed Rootkit Targeting HP Enterprise Servers with Data Wiping Attacks

New iLOBleed Rootkit Targeting HP Enterprise Servers with Data Wiping Attacks

Dec 30, 2022
A previously unknown rootkit has been found setting its sights on Hewlett-Packard Enterprise's Integrated Lights-Out ( iLO ) server management technology to carry out in-the-wild attacks that tamper with the firmware modules and completely wipe data off the infected systems. The discovery, which is the first instance of real-world malware in iLO firmware, was documented by Iranian cybersecurity firm Amnpardaz this week. "There are numerous aspects of iLO that make it an ideal utopia for malware and APT groups: Extremely high privileges (above any level of access in the operating system), very low-level access to the hardware, being totally out of the sight of the admins, and security tools, the general lack of knowledge and tools for inspecting iLO and/or protecting it, the persistence it provides for the malware to remain even after changing the operating system, and in particular being always running and never shutting down," the researchers  said . Besides managin...

Ongoing Autom Cryptomining Malware Attacks Using Upgraded Evasion Tactics

Dec 29, 2022
An ongoing crypto mining campaign has upgraded its arsenal while evolving its defense evasion tactics that enable the threat actors to conceal the intrusions and fly under the radar, new research published today has revealed. Since first detected in 2019, a total of 84 attacks against its honeypot servers have been recorded to date, four of which transpired in 2021, according to researchers from DevSecOps and cloud security firm Aqua Security, who have been tracking the malware operation for the past three years. That said, 125 attacks have been spotted in the wild in the third quarter of 2021 alone, signaling that the attacks have not slowed down. Initial attacks involved executing a malicious command upon running a vanilla image named "alpine:latest" that resulted in the download of a shell script named "autom.sh." "Adversaries commonly use vanilla images along with malicious commands to perform their attacks, because most organizations trust the official...

New Android Malware Targeting Brazil's Itaú Unibanco Bank Customers

Dec 27, 2022
Researchers have discovered a new Android banking malware that targets Brazil's Itaú Unibanco with the help of lookalike Google Play Store pages to carry out fraudulent financial transactions on victim devices without their knowledge. "This application has a similar icon and name that could trick users into thinking it is a legitimate app related to Itaú Unibanco," Cyble researchers  said  in a report published last week. "The [threat actor] has created a fake Google Play Store page and hosted the malware that targets Itaú Unibanco on it under the name  'sincronizador.apk .'" The tactic of leveraging fake app store pages as a lure is not new. In March, Meta (previously Facebook)  disclosed  details of an attack campaign that used its platform as part of a broader operation to spy on Uyghur Muslims using rogue third-party websites that used replica domains for popular news portals and websites designed to resemble third-party Android app stores, where attacke...
