A new powerful rootkit-enabled spyware operation has been discovered wherein hackers are distributing multifunctional malware disguised as cracked software or trojanized app posing as legitimate software like video players, drivers and even anti-virus products. While the rootkit malware—dubbed Scranos —which was first discovered late last year, still appears to be a work in progress, it is continuously evolving, testing new components and regularly making an improvement to old components, which makes it a significant threat. Scranos features a modular design that has already gained capabilities to steal login credentials and payment accounts from various popular services, exfiltrate browsing history and cookies, get YouTube subscribers, display ads, as well as download and execute any payload. According to a 48 page in-depth report Bitdefender shared with The Hacker News prior to its release, the malware gains persistence on infected machines by installing a digitally-signed ...

Security researchers have discovered what appears to be an experimental Linux rootkit designed to infect its highly select victims during a classic drive-by website attack. The malware allows hackers to inject code directly in any infected web page. The new malware, discovered on November 13 of this year, was written especially for servers that run Debian Squeeze and NGINX, on 64 bits. About Rootkit :  Rootkit.Linux.Snakso.a is designed to infect the Linux kernel version 2.6.32-5-amd64 and adds an iframe to all served web pages by the infected Linux server via the nginx proxy.  Based on research, the rootkit may have been created by a Russia-based attacker. The recently discovered malware is very dangerous because it does not infect a specific website. It infects the entire server and this can endanger all websites hosted on that server. Drive-by-downloads expose web surfers to malicious code that attempt to exploit unpatched software vulnerabilities in the...

RKAnalyzer - kernel level rootkit analyzer ! RKAnalyzer is a kernel level rootkit analyzer and defender using Hardware Virtualization Techniques, based on the BitVisor Project(A VMM developed by Tsukuba University and open-sourced under BSD License). It tries to monitor kernel level rootkits' actions and log them. What differs RKAnalyzer with tranditional detection softwares(i.e. Rootkit Revealer, IceSword) is that RKAnalyzer actively intercepts rootkit actions, rather than reacting to rootkit after already infected. Also, RKAnalyzer support analysis mode, which differs from defend mode by presenting a much more transparent environment, in which rootkit would consider itself running without being monitored.

New research has found that the DOS-to-NT path conversion process could be exploited by threat actors to achieve rootkit-like capabilities to conceal and impersonate files, directories, and processes. "When a user executes a function that has a path argument in Windows, the DOS path at which the file or folder exists is converted to an NT path," SafeBreach security researcher Or Yair  said  in an analysis, which was  presented  at the Black Hat Asia conference last week. "During this conversion process, a known issue exists in which the function removes trailing dots from any path element and any trailing spaces from the last path element. This action is completed by most user-space APIs in Windows." These so-called MagicDot paths allow for rootkit-like functionality that's accessible to any unprivileged user, who could then weaponize them to carry out a series of malicious actions without having admin permissions and remain undetected. They include the ab...

On February 6, 2011, as part of their attack on HBGary , the Anonymous group social engineered administrator of rootkit.com , Jussi Jaakonaho, to gain root access to rootkit.com . The entire MySQL database backup was then released by Anonymous and announced using HBGary's CEO Twitter account, @aaronbarr   : Sup, here's rootkit.com MySQL Backup https://stfu.cc/rootkit_com_mysqlbackup_02_06_11.gz #hbgary #rootkit #anonymous.   The table pic shown is the list of accounts found in rootkit.com MySQL database backup with passwords in cleartext.

A new malware campaign has been observed leveraging social engineering tactics to deliver an open-source rootkit called r77 . The activity, condemned OBSCURE#BAT by Securonix, enables threat actors to establish persistence and evade detection on compromised systems. It's currently not known who is behind the campaign. The rootkit "has the ability to cloak or mask any file, registry key or task beginning with a specific prefix," security researchers Den Iuzvyk and Tim Peck said in a report shared with The Hacker News. "It has been targeting users by either masquerading as legitimate software downloads or via fake captcha social engineering scams." The campaign is designed to mainly target English-speaking individuals, particularly the United States, Canada, Germany, and the United Kingdom. OBSCURE#BAT gets its name from the fact that the starting point of the attack is an obfuscated Windows batch script that, in turn, executes PowerShell commands to activ...

A zero-day software vulnerability discovered deep in the firmware of many Apple computers could allows an attacker to modify the system’s BIOS and install a rootkit , potentially gaining complete control of the victim’s Mac. The critical vulnerability, discovered by well-known OS X security researcher Pedro Vilaca, affects Mac computers shipped before mid-2014 that are allowed to go into sleep mode. While studying Mac security, Vilaca found that it’s possible to tamper with Apple computer’s UEFI (unified extensible firmware interface) code. UEFI is a low-level firmware designed to improve upon computer’s BIOS, which links a computer's hardware and operating system at startup and is typically not accessible to users. But… Vilaca found that the machine’s UEFI code can be unlocked after a computer is put to sleep and then brought back up. " And you ask, what the hell does this mean? " Vilaca wrote in a blog post published Friday. " It means th...

A recently patched security flaw in Google Chrome and other Chromium web browsers was exploited as a zero-day by North Korean actors in a campaign designed to deliver the FudModule rootkit. The development is indicative of the persistent efforts made by the nation-state adversary, which has made a habit of incorporating rafts of Windows zero-day exploits into its arsenal in recent months. Microsoft, which detected the activity on August 19, 2024, attributed it to a threat actor it tracks as Citrine Sleet (formerly DEV-0139 and DEV-1222), which is also known as AppleJeus, Labyrinth Chollima, Nickel Academy, and UNC4736 . It's assessed to be a sub-cluster within the Lazarus Group (aka Diamond Sleet and Hidden Cobra). It's worth mentioning that the use of the AppleJeus malware has also been previously attributed by Kaspersky to another Lazarus subgroup called BlueNoroff (aka APT38, Nickel Gladstone, and Stardust Chollima), indicative of the infrastructure and toolset sharin...

Here's some bad news for Android users again. Nearly 3 Million Android devices worldwide are vulnerable to man-in-the-middle (MITM) attacks that could allow attackers to remotely execute arbitrary code with root privileges, turning over full control of the devices to hackers. According to a new report from security rating firm BitSight, the issue is due to a vulnerability in the insecure implementation of the OTA (Over-the-Air) update mechanism used by certain low-cost Android devices, including BLU Studio G from US-based Best Buy. Backdoor/Rootkit Comes Pre-installed The vulnerable OTA mechanism, which is associated with Chinese mobile firm Ragentek Group, contains a hidden binary — resides as /system/bin/debugs — that runs with root privileges and communicates over unencrypted channels with three hosts. According to the researchers, this privileged binary not only exposes user-specific information to MITM attackers but also acts as a rootkit, potentially allowing ...

A new dangerous variant of ZeuS Banking Trojan has been identified by Comodo AV labs which is signed by stolen Digital Certificate which belongs to Microsoft Developer to avoid detection from Web browsers and anti-virus systems. Every Windows PC in the world is set to accept software " signed " with Microsoft's digital certificates of authenticity, an extremely sensitive cryptography seal. Cyber Criminals somehow managed to hack valid Microsoft digital certificate, used it to trick users and admins into trusting the file. Since the executable is digitally signed by the Microsoft developer no antivirus tool could find it as malicious. Digitally signed malware received a lot of media attention last year. Reportedly, more than 200,000 unique malware binaries were discovered in past two years signed with valid digital signatures. A Comodo User submitted a sample of the malicious software that attempts to trick user by masquerading itself as file of Intern...

An unknown Chinese state-sponsored hacking group has been linked to a novel piece of malware aimed at Linux servers. French cybersecurity firm ExaTrack, which found three samples of the previously documented malicious software that date back to early 2022, dubbed it  Mélofée . The newest of the three artifacts is designed to drop a kernel-mode rootkit that's based on an open source project referred to as  Reptile . "According to the vermagic metadata, it is compiled for a kernel version 5.10.112-108.499.amzn2.x86_64," the company  said  in a report. "The rootkit has a limited set of features, mainly installing a hook designed for hiding itself." Both the implant and the rootkit are said to be deployed using shell commands that download an installer and a custom binary package from a remote server. The installer takes the binary package as an argument and then extracts the rootkit as well as a server implant module that's currently under active develop...

Government, aviation, education, and telecom sectors located in South and Southeast Asia have come under the radar of a new hacking group as part of a highly-targeted campaign that commenced in mid-2022 and continued into the first quarter of 2023. Symantec, by Broadcom Software, is tracking the activity under its insect-themed moniker  Lancefly , with the attacks making use of a "powerful" backdoor called Merdoor. Evidence gathered so far points to the custom implant being utilized as far back as 2018. The ultimate goal of the campaign, based on the tools and the victimology pattern, is assessed to be intelligence gathering. "The backdoor is used very selectively, appearing on just a handful of networks and a small number of machines over the years, with its use appearing to be highly targeted," Symantec  said  in an analysis shared with The Hacker News. "The attackers in this campaign also have access to an updated version of the ZXShell rootkit." ...

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...

The notorious Lazarus Group actors exploited a recently patched privilege escalation flaw in the Windows Kernel as a zero-day to obtain kernel-level access and disable security software on compromised hosts. The vulnerability in question is  CVE-2024-21338  (CVSS score: 7.8), which can permit an attacker to gain SYSTEM privileges. It was resolved by Microsoft earlier this month as part of  Patch Tuesday updates . "To exploit this vulnerability, an attacker would first have to log on to the system," Microsoft  said . "An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system." While there were no indications of active exploitation of CVE-2024-21338 at the time of the release of the updates, Redmond on Wednesday revised its "Exploitability assessment" for the flaw to "Exploitation Detected."  It’s currently not clear when the attacks took place, but the vulnerability...

A financially motivated threat actor has been observed deploying a previously unknown rootkit targeting Oracle Solaris systems with the goal of compromising Automatic Teller Machine (ATM) switching networks and carrying out unauthorized cash withdrawals at different banks using fraudulent cards. Threat intelligence and incident response firm Mandiant is tracking the cluster under the moniker UNC2891, with some of the group's tactics, techniques, and procedures sharing overlaps with that of another cluster dubbed  UNC1945 . The intrusions staged by the actor involve "a high degree of OPSEC and leverage both public and private malware, utilities, and scripts to remove evidence and hinder response efforts," Mandiant researchers  said  in a new report published this week. Even more concerningly, the attacks spanned several years in some cases, during the entirety of which the actor remained undetected by taking advantage of a rootkit called CAKETAP, which is designed to ...

The Continuous Growth of spyware, their existence, and the criminals who produce & spread them are increasing tremendously. It’s difficult to recognize spyware as it is becoming more complex and sophisticated with time, so is spreading most rapidly as an Internet threat. Recently, The security researchers have unearthed a very complex and sophisticated piece of malware that was designed to steal confidential data and has ability able to capture network traffic. The Researchers at the German security company G Data Software , refer the malware as Uroburos , named after an ancient symbol depicting a serpent or dragon eating its own tail, and in correspondence with a string ( Ur0bUr()sGotyOu# ) lurking deep in the malware's code.  The researchers claimed that the malware may have been active for as long as three years before being discovered and appears to have been created by Russian developers. Uroburos is a rootkit designed to steal data from secure fa...

Attackers took over more than 400 packages in the Arch User Repository (AUR) this week and rewrote their build scripts to install a credential stealer on any machine that built them. The malware is a Rust binary built to harvest developer secrets. When it lands with root, it can also load an eBPF rootkit to hide itself. The AUR is Arch Linux's community package collection, and it is separate from the official Arch repositories, which were not affected. If you installed or updated an AUR package on or after June 11, check it against the current affected-package lists before trusting the host. The list of names is large, still growing, and not yet complete. This attack goes after the trust model, not a software flaw. The compromised packages kept their names, their histories, and the trust that came with them. Only the build instructions changed. The trap sat in the recipe, leaving the package itself looking exactly like the software users meant to install. No exploit, no ze...

An investigation into the compromise of an Amazon Web Services (AWS)-hosted infrastructure has led to the discovery of a new GNU/Linux rootkit dubbed LinkPro , according to findings from Synacktiv. "This backdoor features functionalities relying on the installation of two eBPF [extended Berkeley Packet Filter] modules, on the one hand to conceal itself, and on the other hand to be remotely activated upon receiving a 'magic packet,'" security researcher Théo Letailleur said . The infection, per the French cybersecurity company, involved the attackers exploiting an exposed Jenkins server vulnerable to CVE-2024-23897 (CVSS score: 9.8) as the starting point, following which a malicious Docker Hub image named "kvlnt/vv" (now removed) was deployed on several Kubernetes clusters. The Docker image consists of a Kali Linux base along with a folder called "app" containing three files - start.sh, a shell script to start the SSH service and execute the...

WikiLeaks has just published a new set of classified documents linked to another CIA project, dubbed ' Imperial ,' which reveals details of at least three CIA-developed hacking tools and implants designed to target computers running Apple Mac OS X and different flavours of Linux operating systems. If you are a regular reader of THN, you must be aware that this latest revelation by the whistleblower organisation is the part of an ongoing CIA-Vault 7 leaks, marking it as the 18th batch in the series. If you are unaware of the Vault 7 leaks, you can head on to the second of this article for having a brief look on all the leaks at once. Achilles — Tool to Backdoor Mac OS X Disk Images Dubbed Achilles , the hacking tool allows CIA operators to combine malicious Trojan applications with a legitimate Mac OS app into a disk image installer (.DMG) file. The binding tool, the shell script is written in Bash, gives the CIA operators "one or more desired operator specified e...
