Stealthy DBatLoader Malware Loader Spreading Remcos RAT and Formbook in Europe

Stealthy DBatLoader Malware Loader Spreading Remcos RAT and Formbook in Europe
Mar 28, 2023 Malware Attack / Hacking
A new phishing campaign has set its sights on European entities to distribute Remcos RAT and Formbook via a malware loader dubbed  DBatLoader . "The malware payload is distributed through WordPress websites that have authorized SSL certificates, which is a common tactic used by threat actors to evade detection engines," Zscaler researchers Meghraj Nandanwar and Satyam Singh  said  in a report published Monday. The findings build upon a previous report from SentinelOne last month that detailed phishing emails containing malicious attachments that masquerade as financial documents to activate the infection chain. Some of the file formats used to distribute the DBatLoader payload concern the use of a multi-layered obfuscated HTML file and OneNote attachments. The development adds to  growing abuse  of  OneNote files  as an initial vector for malware distribution since late last year in response to Microsoft's decision to block macros by default in files downloaded f

International Law Enforcement Takes Down Infamous NetWire Cross-Platform RAT

International Law Enforcement Takes Down Infamous NetWire Cross-Platform RAT
Mar 10, 2023 Cyber Crime / Cyber Threat
A coordinated international law enforcement exercise has taken down the online infrastructure associated with a cross-platform remote access trojan (RAT) known as NetWire . Coinciding with the seizure of the sales website www.worldwiredlabs[.]com, a Croatian national who is suspected to be the website's administrator has been arrested. While the suspect's name was not released, investigative journalist Brian Krebs  identified  Mario Zanko as the owner of the domain. "NetWire is a licensed commodity RAT offered in underground forums to non-technical users to carry out their own criminal activities," Europol's European Cybercrime Center (EC3)  said  in a tweet. Advertised  since   at least 2012 , the malware is typically distributed via  malspam campaigns  and gives a remote attacker complete control over a Windows, macOS, or Linux system. It also comes with password-stealing and keylogging capabilities. The U.S. Department of Justice (DoJ)  said  an investiga

Parallax RAT Targeting Cryptocurrency Firms with Sophisticated Injection Techniques

Parallax RAT Targeting Cryptocurrency Firms with Sophisticated Injection Techniques
Mar 01, 2023 Cryptocurrency / Cyber Attack
Cryptocurrency companies are being targeted as part of a new campaign that delivers a remote access trojan called Parallax RAT. The malware "uses injection techniques to hide within legitimate processes, making it difficult to detect," Uptycs  said  in a new report. "Once it has been successfully injected, attackers can interact with their victim via Windows Notepad that likely serves as a communication channel." Parallax RAT  grants attackers remote access to victim machines. It comes with features to upload and download files as well as record keystrokes and screen captures. It has been put to use since early 2020 and was  previously delivered  via COVID-19-themed lures. In February 2022, Proofpoint  detailed  an activity cluster dubbed TA2541 targeting aviation, aerospace, transportation, manufacturing, and defense industries using different RATs, including Parallax. The first payload is a Visual C++ malware that employs the  process hollowing  technique to

Android Users Beware: New Hook Malware with RAT Capabilities Emerges
Jan 19, 2023 Mobile Security / Android
The threat actor behind the  BlackRock  and  ERMAC  Android banking trojans has unleashed yet another malware for rent called  Hook  that introduces new capabilities to access files stored in the devices and create a remote interactive session. ThreatFabric, in a  report  shared with The Hacker News, characterized Hook as a novel ERMAC fork that's advertised for sale for $7,000 per month while featuring "all the capabilities of its predecessor." "In addition, it also adds to its arsenal Remote Access Tooling (RAT) capabilities, joining the ranks of families such as  Octo  and  Hydra , which are capable performing a full Device Take Over (DTO), and complete a full fraud chain, from PII exfiltration to transaction, with all the intermediate steps, without the need of additional channels," the Dutch cybersecurity firm said. A majority of the financial apps targeted by the malware are located in the U.S., Spain, Australia, Poland, Canada, Turkey, the U.K., Fran

Earth Bogle Campaign Unleashes NjRAT Trojan on Middle East and North Africa

Earth Bogle Campaign Unleashes NjRAT Trojan on Middle East and North Africa
Jan 18, 2023 Cyber Threat / Malware
An ongoing campaign dubbed  Earth Bogle  is leveraging geopolitical-themed lures to deliver the NjRAT remote access trojan to victims across the Middle East and North Africa. "The threat actor uses public cloud storage services such as files[.]fm and failiem[.]lv to host malware, while compromised web servers distribute NjRAT," Trend Micro  said  in a report published Wednesday. Phishing emails, typically tailored to the victim's interests, are loaded with malicious attachments to activate the infection routine. This takes the form of a Microsoft Cabinet (CAB) archive file containing a Visual Basic Script dropper to deploy the next-stage payload. Alternatively, it's suspected that the files are distributed via social media platforms such as Facebook and Discord, in some cases even creating bogus accounts to serve ads on pages impersonating legitimate news outlets. The CAB files, hosted on cloud storage services, also masquerade as sensitive voice recordings to e

Cybercriminals Using Polyglot Files in Malware Distribution to Fly Under the Radar

Cybercriminals Using Polyglot Files in Malware Distribution to Fly Under the Radar
Jan 13, 2023 Cyber Threat / Malware Detection
Remote access trojans such as StrRAT and Ratty are being distributed as a combination of polyglot and malicious Java archive ( JAR ) files, once again highlighting how threat actors are continuously finding new ways to fly under the radar. "Attackers now use the polyglot technique to confuse security solutions that don't properly validate the JAR file format," Deep Instinct security researcher Simon Kenin  said  in a report. Polyglot files  are files that combine syntax from two or more different formats in a manner such that each format can be parsed without raising any error. One such 2022 campaign spotted by the cybersecurity firm involves the use of JAR and MSI formats – i.e., a file that's valid both as a JAR and an MSI installer – to deploy the StrRAT payload. This also means that the file can be executed by both Windows and Java Runtime Environment (JRE) based on how it's interpreted. Another instance involves the use of CAB and JAR polyglots to deli

Sep 28, 2022
A recently discovered malware builder called Quantum Builder is being used to deliver the Agent Tesla remote access trojan (RAT). "This campaign features enhancements and a shift toward LNK (Windows shortcut) files when compared to similar attacks in the past," Zscaler ThreatLabz researchers Niraj Shivtarkar and Avinash Kumar  said  in a Tuesday write-up. Sold on the dark web for €189 a month,  Quantum Builder  is a customizable tool for generating malicious shortcut files as well as HTA, ISO, and PowerShell payloads to deliver next-stage malware on the targeted machines, in this case  Agent Tesla . The multi-stage attack chain starts with a spear-phishing email containing a GZIP archive attachment that includes a shortcut designed to execute PowerShell code responsible for launching a remote HTML application (HTA) using  MSHTA . The phishing emails purport to be an order confirmation message from a Chinese supplier of lump and rock sugar, with the LNK file masqueradin

Researchers Detail OriginLogger RAT — Successor to Agent Tesla Malware
Sep 14, 2022
Palo Alto Networks Unit 42 has detailed the inner workings of a malware called  OriginLogger , which has been touted as a successor to the widely used information stealer and remote access trojan (RAT) known as  Agent Tesla . A .NET based keylogger and remote access, Agent Tesla has had a long-standing presence in the threat landscape, allowing malicious actors to gain remote access to targeted systems and beacon sensitive information to an actor-controlled domain. Known to be used in the wild since 2014, it's advertised for sale on dark web forums and is generally distributed through malicious spam emails as an attachment. In February 2021, cybersecurity firm Sophos  disclosed two new variants  of the commodity malware (version 2 and 3) that featured capabilities to steal credentials from web browsers, email apps, and VPN clients, as well as use Telegram API for command-and-control. Now according to Unit 42 researcher Jeff White, what has been tagged as Agent Tesla version 3

Chinese Hackers Target Government Officials in Europe, South America, and Middle East

Chinese Hackers Target Government Officials in Europe, South America, and Middle East
Sep 08, 2022
A Chinese hacking group has been attributed to a new campaign aimed at infecting government officials in Europe, the Middle East, and South America with a modular malware known as PlugX. Cybersecurity firm Secureworks said it identified the intrusions in June and July 2022, once again demonstrating the adversary's continued focus on espionage against governments around the world. "PlugX is modular malware that contacts a command and control (C2) server for tasking and can download additional plugins to enhance its capability beyond basic information gathering," Secureworks Counter Threat Unit (CTU) said in a report shared with The Hacker News. Bronze President is a China-based threat actor active since at least July 2018 and is likely estimated to be a state-sponsored group that leverages a mix of proprietary and publicly available tools to compromise and collect data from its targets. It's also publicly documented under other names such as HoneyMyte, Mustang P

Meet Borat RAT, a New Unique Triple Threat

Meet Borat RAT, a New Unique Triple Threat
Aug 22, 2022
Atlanta-based cyber risk intelligence company, Cyble discovered a new Remote Access Trojan (RAT) malware. What makes this particular RAT malware distinct enough to be named after the  comic creation of Sacha Baron Cohen ? RAT malware typically helps cybercriminals gain complete control of a victim's system, permitting them to access network resources, files, and power to toggle the mouse and keyboard. Borat RAT malware goes beyond the standard features and enables threat actors to deploy ransomware and  DDoS attacks . It also increases the number of threat actors who can launch attacks, sometimes appealing to the lowest common denominator. The added functionality of carrying out DDoS attacks makes it insidious and a risk to today's digital organizations. Ransomware has been the most common top attack type for over  three years . According to an IBM report, REvil was the most common ransomware strain, consisting of about  37%  of all ransomware attacks. Borat RAT is a unique

Aug 01, 2022
A 24-year-old Australian national has been charged for his purported role in the creation and sale of spyware for use by domestic violence perpetrators and child sex offenders. Jacob Wayne John Keen, who currently resides at Frankston, Melbourne, is said to have created the remote access trojan (RAT) when he was 15, while also administering the tool from 2013 until its shutdown in 2019 as part of a coordinated Europol-led exercise. "The Frankston man engaged with a network of individuals and sold the spyware, named Imminent Monitor (IM), to more than 14,500 individuals across 128 countries," the Australian Federal Police (AFP)  alleged  in a press release over the weekend. The defendant has been slapped with six counts of committing a computer offense by developing and supplying the malware, in addition to profiting off its illegal sale. Another woman, aged 42, who lives in the same home as the accused and is identified as his mother by  The Guardian , has also been c

Researchers Find New Malware Attacks Targeting Russian Government Entities
May 25, 2022
An unknown advanced persistent threat (APT) group has been linked to a series of spear-phishing attacks targeting Russian government entities since the onset of the Russo-Ukrainian war in late February 2022. "The campaigns [...] are designed to implant a Remote Access Trojan (RAT) that can be used to surveil the computers it infects, and run commands on them remotely," Malwarebytes  said  in a technical report published Tuesday. The cybersecurity company attributed the attacks with low confidence to a Chinese hacking group, citing infrastructure overlaps between the RAT and Sakula Rat malware used by a threat actor known as  Deep Panda . The attack chains, while leveraging different lures over the course of two months, all employed the same malware barring small differences in the source code. The campaign is said to have commenced around February 26, days after Russia's military invasion of Ukraine, with the emails distributing the RAT under the guise of an interac

Chinese Hackers Targeting Russian Military Personnel with Updated PlugX Malware
Apr 27, 2022
A China-linked government-sponsored threat actor observed striking European diplomatic entities in March may have been targeting Russian government officials with an updated version of a remote access trojan called  PlugX . Secureworks attributed the attempted intrusions to a threat actor it tracks as Bronze President, and by the wider cybersecurity community under the monikers Mustang Panda, TA416, HoneyMyte, RedDelta, and PKPLUG. "The war in Ukraine has prompted many countries to deploy their cyber capabilities to gain insight about global events, political machinations, and motivations," the cybersecurity firm  said  in a report shared with The Hacker News. "This desire for situational awareness often extends to collecting intelligence from allies and 'friends.'" Bronze President, active since at least July 2018, has a history of conducting espionage operations by leveraging custom and publicly available tools to compromise, maintain long-term access,

Experts Warn of Hacking Group Targeting Aviation and Defense Sectors

Experts Warn of Hacking Group Targeting Aviation and Defense Sectors
Feb 15, 2022
Entities in the aviation, aerospace, transportation, manufacturing, and defense industries have been targeted by a persistent threat group since at least 2017 as part of a string of spear-phishing campaigns mounted to deliver a variety of remote access trojans (RATs) on compromised systems. The use of commodity malware such as AsyncRAT and NetWire, among others, has led enterprise security firm Proofpoint to a "cybercriminal threat actor" codenamed TA2541 that employs "broad targeting with high volume messages." The ultimate objective of the intrusions is unknown as yet. Social engineering lures used by the group does not rely on topical themes but rather leverages decoy messages related to  aviation , logistics, transportation, and travel. That said, TA2541 did briefly pivot to  COVID-19-themed lures  in the spring of 2020, distributing emails concerning cargo shipments of personal protective equipment (PPE) or testing kits. "While TA2541 is consistent i

New CapraRAT Android Malware Targets Indian Government and Military Personnel
Feb 07, 2022
A politically motivated advanced persistent threat (APT) group has expanded its malware arsenal to include a new remote access trojan (RAT) in its espionage attacks aimed at Indian military and diplomatic entities. Called  CapraRAT  by Trend Micro, the implant is an Android RAT that exhibits a high "degree of crossover" with another Windows malware known as CrimsonRAT that's associated with Earth Karkaddan, a threat actor that's also tracked under the monikers APT36, Operation C-Major, PROJECTM, Mythic Leopard, and Transparent Tribe. The first concrete signs of APT36's existence  appeared  in  2016  as the group began distributing information-stealing malware through phishing emails with malicious PDF attachments targeting Indian military and government personnel. The group is believed to be of  Pakistani origin  and operational since at least 2013. The threat actor is also known to be consistent in its modus operandi, with the attacks predominantly banking o

North Korean Hackers Return with Stealthier Variant of KONNI RAT Malware

North Korean Hackers Return with Stealthier Variant of KONNI RAT Malware
Jan 28, 2022
A cyberespionage group with ties to North Korea has resurfaced with a stealthier variant of its remote access trojan called Konni to attack political institutions located in Russia and South Korea. "The authors are constantly making code improvements," Malwarebytes researcher Roberto Santos  said . "Their efforts are aimed at breaking the typical flow recorded by sandboxes and making detection harder, especially via regular signatures as critical parts of the executable are now encrypted." Most  recent intrusions  staged by the group, believed to be operating under the Kimsuky umbrella, involved targeting the Russian Federation's Ministry of Foreign Affairs (MID) with New Year lures to compromise Windows systems with malware. The infections, as with other attacks of this kind, starts with a malicious Microsoft Office document that, when opened, initiates a mult-stage process that involves several moving parts that help the attackers elevate privileges, eva

Hackers Use Cloud Services to Distribute Nanocore, Netwire, and AsyncRAT Malware

Hackers Use Cloud Services to Distribute Nanocore, Netwire, and AsyncRAT Malware
Jan 12, 2022
Threat actors are actively incorporating public cloud services from Amazon and Microsoft into their malicious campaigns to deliver commodity remote access trojans (RATs) such as  Nanocore ,  Netwire , and  AsyncRAT  to siphon sensitive information from compromised systems. The spear-phishing attacks, which commenced in October 2021, have primarily targeted entities located in the U.S., Canada, Italy, and Singapore, researchers from Cisco Talos said in a report shared with The Hacker News. Using existing legitimate infrastructure to facilitate intrusions is increasingly becoming part of an attacker's playbook as it obviates the need to host their own servers, not to mention be used as a cloaking mechanism to evade detection by security solutions. In recent months, collaboration and communication tools like  Discord, Slack, and Telegram  have found a place in many an infection chain to  commandeer and exfiltrate data  from the victim machines. Viewed in that light, the abuse of

'Lone Wolf' Hacker Group Targeting Afghanistan and India with Commodity RATs

'Lone Wolf' Hacker Group Targeting Afghanistan and India with Commodity RATs
Oct 22, 2021
A new malware campaign targeting Afghanistan and India is exploiting a now-patched, 20-year-old flaw affecting Microsoft Office to deploy an array of commodity remote access trojans (RATs) that allow the adversary to gain complete control over the compromised endpoints. Cisco Talos attributed the cyber campaign to a "lone wolf" threat actor operating a Lahore-based fake IT company called Bunse Technologies as a front to carry out the malicious activities, while also having a history of sharing content that's in favor of Pakistan and Taliban dating all the way back to 2016. The attacks work by taking advantage of political and government-themed lure domains that host the malware payloads, with the infection chains leveraging weaponized RTF documents and PowerShell scripts that distribute malware to victims. Specifically, the laced RTF files were found exploiting  CVE-2017-11882  to execute a PowerShell command that's responsible for deploying additional malware to
