Backdoor | Breaking Cybersecurity News | The Hacker News

Thai government officials have emerged as the target of a new campaign that leverages a technique called DLL side-loading to deliver a previously undocumented backdoor dubbed Yokai . "The target of the threat actors were Thailand officials based on the nature of the lures," Nikhil Hegde, senior engineer for Netskope's Security Efficacy team, told The Hacker News. "The Yokai backdoor itself is not limited and can be used against any potential target." The starting point of the attack chain is a RAR archive containing two Windows shortcut files named in Thai that translate to "United States Department of Justice.pdf" and "United States government requests international cooperation in criminal matters.docx." The exact initial vector used to deliver the payload is currently not known, although Hegde speculated that it would likely be spear-phishing due to the lures employed and the fact that RAR files have been used as malicious attachment...

A previously undocumented backdoor named Msupedge has been put to use against a cyber attack targeting an unnamed university in Taiwan. "The most notable feature of this backdoor is that it communicates with a command-and-control (C&C) server via DNS traffic," the Symantec Threat Hunter Team, part of Broadcom, said in a report shared with The Hacker News. The origins of the backdoor are presently unknown as are the objectives behind the attack. The initial access vector that likely facilitated the deployment of Msupedge is said to involve the exploitation of a recently disclosed critical flaw impacting PHP ( CVE-2024-4577 , CVSS score: 9.8), which could be used to achieve remote code execution . The backdoor in question is a dynamic-link library (DLL) that's installed in the paths "csidl_drive_fixed\xampp\" and "csidl_system\wbem\." One of the DLLs, wuplog.dll, is launched by the Apache HTTP server (httpd). The parent process for the second ...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

Threat actors have been found exploiting a critical flaw in Magento to inject a persistent backdoor into e-commerce websites. The attack leverages  CVE-2024-20720  (CVSS score: 9.1), which has been described by Adobe as a case of "improper neutralization of special elements" that could pave the way for arbitrary code execution. It was  addressed  by the company as part of security updates released on February 13, 2024. Sansec said it discovered a "cleverly crafted layout template in the database" that's being used to automatically inject malicious code to execute arbitrary commands. "Attackers combine the Magento layout parser with the beberlei/assert package (installed by default) to execute system commands," the company  said . "Because the layout block is tied to the checkout cart, this command is executed whenever <store>/checkout/cart is requested." The command in question is  sed , which is used to insert a code execution ...

Red Hat on Friday released an "urgent security alert" warning that two versions of a popular data compression library called  XZ Utils  (previously LZMA Utils) have been backdoored with malicious code designed to allow unauthorized remote access. The software supply chain compromise, tracked as  CVE-2024-3094 , has a CVSS score of 10.0, indicating maximum severity. It impacts XZ Utils versions 5.6.0 (released February 24) and 5.6.1 (released March 9). "Through a series of complex obfuscations, the liblzma build process extracts a prebuilt object file from a disguised test file existing in the source code, which is then used to modify specific functions in the liblzma code," the IBM subsidiary  said  in an advisory. "This results in a modified liblzma library that can be used by any software linked against this library, intercepting and modifying the data interaction with this library." Specifically, the nefarious code baked into the code is  designed...

Cybersecurity researchers have discovered a previously undocumented advanced backdoor dubbed  Deadglyph  employed by a threat actor known as Stealth Falcon as part of a cyber espionage campaign. "Deadglyph's architecture is unusual as it consists of cooperating components – one a native x64 binary, the other a .NET assembly," ESET  said  in a  new report  shared with The Hacker News. "This combination is unusual because malware typically uses only one programming language for its components. This difference might indicate separate development of those two components while also taking advantage of unique features of the distinct programming languages they utilize." It's also suspected that the use of different programming languages is a deliberate tactic to hinder analysis, making it a lot more challenging to navigate and debug. Unlike other traditional backdoors of its kind, the commands are received from an actor-controlled server in the form of...

An Iranian nation-state threat actor has been linked to a new wave of phishing attacks targeting Israel that's designed to deploy an updated version of a Windows backdoor called PowerLess . Cybersecurity firm Check Point is tracking the activity cluster under its mythical creature handle  Educated Manticore , which exhibits "strong overlaps" with a hacking crew known as APT35, Charming Kitten, Cobalt Illusion, ITG18, Mint Sandstorm (formerly Phosphorus), TA453, and Yellow Garuda. "Like many other actors, Educated Manticore has adopted recent trends and started using ISO images and possibly other archive files to initiate infection chains," the Israeli company  said  in a technical report published today. Active since at least 2011, APT35 has cast a  wide net of targets  by leveraging  fake social media personas ,  spear-phishing techniques , and  N-day vulnerabilities in internet-exposed applications  to gain initial access and drop vario...

Telecommunication providers in the Middle East are the subject of new cyber attacks that commenced in the first quarter of 2023. The intrusion set has been attributed to a Chinese cyber espionage actor associated with a long-running campaign dubbed  Operation Soft Cell  based on tooling overlaps. "The initial attack phase involves infiltrating Internet-facing Microsoft Exchange servers to deploy web shells used for command execution," researchers from SentinelOne and QGroup said in a  new technical report  shared with The Hacker News. "Once a foothold is established, the attackers conduct a variety of reconnaissance, credential theft, lateral movement, and data exfiltration activities." Operation Soft Cell, according to  Cybereason , refers to malicious activities undertaken by China-affiliated actors targeting telecommunications providers since at least 2012. The Soft Cell threat actor, also tracked by Microsoft as  Gallium , is known to target unpa...

The China-aligned Mustang Panda actor has been observed using a hitherto unseen custom backdoor called  MQsTTang  as part of an ongoing social engineering campaign that commenced in January 2023. "Unlike most of the group's malware, MQsTTang doesn't seem to be based on existing families or publicly available projects," ESET researcher Alexandre Côté Cyr  said  in a new report. Attack chains orchestrated by the group have stepped up targeting of European entities in the wake of  Russia's full-scale invasion of Ukraine  last year. The victimology of the current activity is unclear, but the Slovak cybersecurity company said the decoy filenames are in line with the group's previous campaigns that target European political organizations. That said, ESET also observed attacks against unknown entities in Bulgaria and Australia, as well as a governmental institution in Taiwan, indicating a broader focus on Europe and Asia. Mustang Panda has a  history ...

An espionage-focused threat actor has been observed using a steganographic trick to conceal a previously undocumented backdoor in a Windows logo in its attacks against Middle Eastern governments. Broadcom's Symantec Threat Hunter Team attributed the updated tooling to a hacking group it tracks under the name  Witchetty , which is also known as  LookingFrog , a subgroup operating under the TA410 umbrella. Intrusions involving TA410 – which is believed to share connections with a Chinese threat group known as APT10 (aka Cicada, Stone Panda, or TA429) – primarily feature a modular implant called LookBack. Symantec's latest analysis of attacks between February and September 2022, during which the group targeted the governments of two Middle Eastern countries and the stock exchange of an African nation, highlights the use of another backdoor dubbed Stegmap. The new malware leverages  steganography  – a technique used to embed a message (in this case, malware) in a n...

An advanced persistent threat group with links to Iran has updated its malware toolset to include a novel PowerShell-based implant called PowerLess Backdoor , according to new research published by Cybereason. The Boston-headquartered cybersecurity company attributed the malware to a hacking group known as Charming Kitten (aka Phosphorous, APT35, or  TA453 ), while also calling out the backdoor's evasive PowerShell execution. "The PowerShell code runs in the context of a .NET application, thus not launching 'powershell.exe' which enables it to evade security products," Daniel Frank, senior malware researcher at Cybereason,  said . "The toolset analyzed includes extremely modular, multi-staged malware that decrypts and deploys additional payloads in several stages for the sake of both stealth and efficacy." The threat actor, which is active since at least 2017, has been behind a series of campaigns in recent years, including those wherein the adversa...

An Iranian state-sponsored actor has been observed scanning and attempting to abuse the Log4Shell flaw in publicly-exposed Java applications to deploy a hitherto undocumented PowerShell-based modular backdoor dubbed " CharmPower " for follow-on post-exploitation. "The actor's attack setup was obviously rushed, as they used the basic open-source tool for the exploitation and based their operations on previous infrastructure, which made the attack easier to detect and attribute," researchers from Check Point  said  in a report published this week. The Israeli cybersecurity company linked the attack to a group known as  APT35 , which is also tracked using the codenames Charming Kitten, Phosphorus, and TA453, citing overlaps with toolsets previously identified as infrastructure used by the threat actor. Log4Shell  aka CVE-2021-44228 (CVSS score: 10.0) concerns a critical security vulnerability in the popular Log4j logging library that, if successfully exploite...

A U.S. federal government commission associated with international rights has been targeted by a backdoor that reportedly compromised its internal network in what the researchers described as a "classic APT-type operation."  "This attack could have given total visibility of the network and complete control of a system and thus could be used as the first step in a multi-stage attack to penetrate this, or other networks more deeply," Czech security company Avast  said  in a report published last week. The name of the federal entity was not disclosed, but reports from  Ars Technica  and  The Record  tied it to the U.S. Commission on International Religious Freedom ( USCIRF ). Avast said it was making its findings public after unsuccessful attempts to directly notify the agency about the intrusion and through other channels put in place by the U.S. government. At this stage, only "parts of the attack puzzle" have been uncovered, leaving the door open ...

A newly discovered botnet capable of staging distributed denial-of-service (DDoS) attacks targeted unpatched Ribbon Communications (formerly Edgewater Networks) EdgeMarc appliances belonging to telecom service provider AT&T by exploiting a four-year-old flaw in the network appliances. Chinese tech giant Qihoo 360's Netlab network security division, which detected the botnet first on October 27, 2021, called it  EwDoor , noting it observed 5,700 compromised IP addresses located in the U.S. during a brief three-hour window. "So far, the EwDoor in our view has undergone three versions of updates, and its main functions can be summarized into two main categories of DDoS attacks and backdoor," the researchers  noted . "Based on the attacked devices are telephone communication related, we presume that its main purpose is DDoS attacks, and gathering of sensitive information, such as call logs." Propagating through a flaw in EdgeMarc devices, EwDoor supports a...

A financially motivated threat actor notorious for setting its sights on retail, hospitality, and entertainment industries has been observed deploying a completely new backdoor on infected systems, indicating the operators are continuously retooling their malware arsenal to avoid detection and stay under the radar. The previously undocumented malware has been dubbed " Sardonic " by Romanian cybersecurity technology company Bitdefender, which it encountered during a  forensic investigation  in the wake of an unsuccessful attack carried out by FIN8 aimed at an unnamed financial institution located in the U.S. Said to be under active development, "Sardonic backdoor is extremely potent and has a wide range of capabilities that help the threat actor leverage new malware on the fly without updating components," Bitdefender researchers Eduard Budaca and Victor Vrabie said in a report shared with The Hacker News. Since emerging on the scene in January 2016, FIN8 has ...

A computer retail company based in the U.S. was the target of a previously undiscovered implant called SideWalk as part of a recent campaign undertaken by a Chinese advanced persistent threat group primarily known for singling out entities in East and Southeast Asia. Slovak cybersecurity firm ESET attributed the malware to an advanced persistent threat it tracks under the moniker SparklingGoblin, an adversary believed to be connected to the Winnti umbrella group, noting its similarities to another backdoor dubbed  Crosswalk  that was put to use by the same threat actor in 2019. "SideWalk is a modular backdoor that can dynamically load additional modules sent from its C&C [command-and-control] server, makes use of Google Docs as a  dead drop resolver , and  Cloudflare workers  as a C&C server," ESET researchers Thibaut Passilly and Mathieu Tartare  said  in a report published Tuesday. "It can also properly handle communication behind a prox...

A threat actor believed to be working on behalf of Chinese state-sponsored interests was recently observed targeting a Russia-based defense contractor involved in designing nuclear submarines for the naval arm of the Russian Armed Forces. The phishing attack, which singled out a general director working at the Rubin Design Bureau, leveraged the infamous "Royal Road" Rich Text Format (RTF) weaponizer to deliver a previously undocumented Windows backdoor dubbed " PortDoor ," according to Cybereason's Nocturnus threat intelligence team. "Portdoor has multiple functionalities, including the ability to do reconnaissance, target profiling, delivery of additional payloads, privilege escalation, process manipulation static detection antivirus evasion, one-byte XOR encryption, AES-encrypted data exfiltration and more," the researchers  said  in a write-up on Friday. Rubin Design Bureau is a submarine design center located in Saint Petersburg, accounting fo...

Gigaset has revealed a malware infection discovered in its Android devices was the result of a compromise of a server belonging to an external update service provider. Impacting older smartphone models — GS100, GS160, GS170, GS180, GS270 (plus), and GS370 (plus) series — the malware took the form of multiple  unwanted apps  that were downloaded and installed through a pre-installed system update app. The infections are said to have occurred starting  March 27 . The German manufacturer of telecommunications devices said it took steps to alert the update service provider of the issue, following which further infections were prevented on April 7. "Measures have been taken to automatically rid infected devices of the malware. In order for this to happen the devices must be connected to the internet (WLAN, WiFi or mobile data). We also recommend connecting the devices to their chargers. Affected devices should automatically be freed from the malware within 8 hours," the ...

A new spear-phishing campaign is targeting professionals on LinkedIn with weaponized job offers in an attempt to infect targets with a sophisticated backdoor trojan called "more_eggs." To increase the odds of success, the phishing lures take advantage of malicious ZIP archive files that have the same name as that of the victims' job titles taken from their LinkedIn profiles. "For example, if the LinkedIn member's job is listed as Senior Account Executive—International Freight the malicious zip file would be titled Senior Account Executive—International Freight position (note the 'position' added to the end)," cybersecurity firm eSentire's Threat Response Unit (TRU)  said  in an analysis. "Upon opening the fake job offer, the victim unwittingly initiates the stealthy installation of the fileless backdoor, more_eggs." Campaigns delivering more_eggs using the  same modus operandi  have been spotted at least since 2018, with the backdo...

As the investigation into the SolarWinds supply-chain attack continues, cybersecurity researchers have disclosed a third malware strain that was deployed into the build environment to inject the backdoor into the company's Orion network monitoring platform. Called " Sunspot ," the malignant tool adds to a growing list of previously disclosed malicious software such as Sunburst and Teardrop. "This highly sophisticated and novel code was designed to inject the Sunburst malicious code into the SolarWinds Orion Platform without arousing the suspicion of our software development and build teams," SolarWinds' new CEO Sudhakar Ramakrishna  explained . While  preliminary evidence  found that operators behind the espionage campaign managed to compromise the software build and code signing infrastructure of SolarWinds Orion platform as early as October 2019 to deliver the Sunburst backdoor, the latest findings reveal a new timeline that establishes the first brea...
