Threat actors have been observed serving malicious code by utilizing Binance's Smart Chain (BSC) contracts in what has been described as the "next level of bulletproof hosting." The campaign, detected two months ago, has been codenamed  EtherHiding  by Guardio Labs. The novel twist marks the latest iteration in an ongoing malware campaign that leverages compromised WordPress sites to serve unsuspecting visitors a fake warning to update their browsers before the sites can be accessed, ultimately leading to the deployment of information stealer malware such as Amadey, Lumma, or RedLine. "While their initial method of hosting code on abused Cloudflare Worker hosts was taken down, they've quickly pivoted to take advantage of the decentralized, anonymous, and public nature of blockchain," security researchers Nati Tal and Oleg Zaytsev  said . "This campaign is up and harder than ever to detect and take down." It's no surprise that threat act...

Microsoft has announced that it  plans  to eliminate NT LAN Manager ( NTLM ) in Windows 11 in the future, as it pivots to alternative methods for authentication and bolster security. "The focus is on strengthening the Kerberos authentication protocol, which has been the default since 2000, and reducing reliance on NT LAN Manager (NTLM)," the tech giant said. "New features for Windows 11 include Initial and Pass Through Authentication Using Kerberos (IAKerb) and a local Key Distribution Center ( KDC ) for Kerberos." IAKerb enables clients to authenticate with Kerberos across a diverse range of network topologies. The second feature, a local Key Distribution Center (KDC) for Kerberos, extends Kerberos support to local accounts. First introduced in the 1990s, NTLM is a  suite of security protocols  intended to provide authentication, integrity, and confidentiality to users. It is a single sign-on (SSO) tool that relies on a challenge-response protocol that proves ...

European Union military personnel and political leaders working on gender equality initiatives have emerged as the target of a new campaign that delivers an updated version of RomCom RAT called  PEAPOD . Cybersecurity firm Trend Micro attributed the attacks to a threat actor it tracks under the name  Void Rabisu , which is also known as Storm-0978, Tropical Scorpius, and UNC2596, and is also believed to be associated with Cuba ransomware. The adversarial collective is something of an unusual group in that it conducts both financial motivated and espionage attacks, blurring the line between their modes of operation. It's also exclusively linked to the use of RomCom RAT. Attacks  involving the use of the backdoor  have singled out Ukraine and countries that support Ukraine in its war against Russia over the past year. Earlier this July, Microsoft implicated Void Rabisu to the exploitation of  CVE-2023-36884 , a remote code execution flaw in Office and Window...

Ransomware attacks have only increased in sophistication and capabilities over the past year. From new evasion and anti-analysis techniques to stealthier variants coded in new languages, ransomware groups have adapted their tactics to effectively bypass common defense strategies.  This article will cover just some of those new developments in Q3-2023 as well as give predictions on quarters to come. The overall aim is to establish a recap of the major targets (both sectoral and nation and region-wise), new techniques employed with an emphasis on major incidents, new developments of concern to potential targets, as well as the shape of things to come in the future of Ransomware development. The increased weaponization of Vulnerabilities to deliver Ransomware: Cyble has observed increased instances of vulnerabilities being used as a vector to deliver ransomware and other malware in recent months, with a particular emphasis on Networking devices. This marks a shift from the previo...

The advanced persistent threat (APT) actor known as  ToddyCat  has been linked to a new set of malicious tools that are designed for data exfiltration, offering a deeper insight into the hacking crew's tactics and capabilities. The  findings  come from Kaspersky, which  first shed light  on the adversary last year, linking it to attacks against high-profile entities in Europe and Asia for nearly three years. While the group's arsenal prominently features Ninja Trojan and a backdoor called Samurai, further investigation has uncovered a whole new set of malicious software developed and maintained by the actor to achieve persistence, conduct file operations, and load additional payloads at runtime. This comprises a collection of loaders that comes with capabilities to launch the Ninja Trojan as a second stage, a tool called LoFiSe to find and collect files of interest, a DropBox uploader to save stolen data to Dropbox, and Pcexter to exfiltrate archive fil...

A piece of malware known as  DarkGate  has been observed being spread via instant messaging platforms such as Skype and Microsoft Teams. In these attacks, the messaging apps are used to deliver a Visual Basic for Applications ( VBA ) loader script that masquerades as a PDF document, which, when opened, triggers the download and execution of an AutoIt script designed to launch the malware. "It's unclear how the originating accounts of the instant messaging applications were compromised, however it is hypothesized to be either through leaked credentials available through underground forums or the previous compromise of the parent organization," Trend Micro  said  in a new analysis published Thursday. DarkGate, first documented by Fortinet in November 2018, is a  commodity malware  that incorporates a wide range of features to harvest sensitive data from web browsers, conduct cryptocurrency mining, and allow its operators to remotely control the infected ...

The AvosLocker ransomware gang has been linked to attacks against critical infrastructure sectors in the U.S., with some of them detected as recently as May 2023. That's according to a new joint cybersecurity advisory released by the U.S. Cybersecurity and Infrastructure Security Agency (CISA) and the Federal Bureau of Investigation (FBI) detailing the ransomware-as-a-service (RaaS) operation's tactics, techniques, and procedures (TTPs). "AvosLocker affiliates compromise organizations' networks by using legitimate software and open-source remote system administration tools," the agencies  said . "AvosLocker affiliates then use exfiltration-based data extortion tactics with threats of leaking and/or publishing stolen data." The ransomware strain  first emerged  on the scene in mid-2021, and has since leveraged sophisticated techniques to disable antivirus protection as a detection evasion measure. It affects Windows, Linux, and VMware ESXi environment...

A malicious package hosted on the NuGet package manager for the .NET Framework has been found to deliver a remote access trojan called SeroXen RAT. The package, named Pathoschild.Stardew.Mod.Build.Config and published by a user named  Disti , is a typosquat of a legitimate package called  Pathoschild.Stardew.ModBuildConfig , software supply chain security firm Phylum  said  in a report today. While the real package has received nearly 79,000 downloads to date, the malicious variant is said to have artificially inflated its download count after being published on October 6, 2023, to surpass 100,000 downloads. The profile behind the package has published six other packages that have attracted no less than 2.1 million downloads cumulatively, four of which masquerade as libraries for various crypto services like Kraken, KuCoin, Solana, and Monero, but are also designed to deploy SeroXen RAT. The attack chain is initiated during installation of the package by means o...

The threat actors behind ShellBot are leveraging IP addresses transformed into their hexadecimal notation to infiltrate poorly managed Linux SSH servers and deploy the DDoS malware. "The overall flow remains the same, but the download URL used by the threat actor to install ShellBot has changed from a regular IP address to a hexadecimal value," the AhnLab Security Emergency response Center (ASEC) said in a new report published today. ShellBot, also known by the name PerlBot, is known to breach servers that have weak SSH credentials by means of a dictionary attack , with the malware used as a conduit to stage DDoS attacks and deliver cryptocurrency miners . Developed in Perl, the malware uses the IRC protocol to communicate with a command-and-control (C2) server. The latest set of observed attacks involving ShellBot has been found to install the malware using hexadecimal IP addresses – hxxp://0x2763da4e/ which corresponds to 39.99.218[.]78 – in what's seen as an a...

ChatGPT has transformed the way businesses generate textual content, which can potentially result in a quantum leap in productivity. However, Generative AI innovation also introduces a new dimension of data exposure risk, when employees inadvertently type or paste sensitive business data into ChatGPT, or similar applications. DLP solutions, the go-to solution for similar challenges, are ill-equipped to handle these challenges, since they focus on file-based data protection. A new report by LayerX, "Browser Security Platform: Guard your Data from Exposure in ChatGPT" ( Download here ), sheds light on the challenges and risks of ungoverned ChatGPT usage. It paints a comprehensive picture of the potential hazards for businesses and then offers a potential solution: browser security platforms. Such platforms provide real-time monitoring and governance over web sessions, effectively safeguarding sensitive data. ChatGPT Data Exposure: By the Numbers Employee usage of GenAI apps has surge...

Microsoft on Wednesday said that a user containment feature in Microsoft Defender for Endpoint helped thwart a "large-scale remote encryption attempt" made by  Akira ransomware actors  targeting an unknown industrial organization in early June 2023. The tech giant's threat intelligence team is tracking the operator as Storm-1567. The attack leveraged devices that were not onboarded to Microsoft Defender for Endpoint as a defense evasion tactic, while also conducting a series of reconnaissance and lateral movement activities prior to encrypting the devices using a compromised user account. But the new  automatic attack disruption capability  meant that the breached accounts are prevented from "accessing endpoints and other resources in the network, limiting attackers' ability to move laterally regardless of the account's Active Directory state or privilege level." In other words, the idea is to cut off all inbound and outbound communication and proh...

Cybersecurity researchers have shed light on a new sophisticated strain of malware that masquerades as a WordPress plugin to stealthily create administrator accounts and remotely control a compromised site. "Complete with a professional looking opening comment implying it is a caching plugin, this rogue code contains numerous functions, adds filters to prevent itself from being included in the list of activated plugins, and has pinging functionality that allows a malicious actor to check if the script is still operational, as well as file modification capabilities," Wordfence  said . The plugin also offers the ability to activate and deactivate arbitrary plugins on the site remotely as well as create rogue admin accounts with the username superadmin and a hard-coded password. In what's seen as an attempt to erase traces of compromise, it features a function named "_pln_cmd_hide" that's designed to remove the superadmin account when it's no longer req...
