Cybercriminals are increasingly leveraging malicious LNK files as an initial access method to download and execute payloads such as Bumblebee, IcedID, and Qakbot. A recent study by cybersecurity experts has shown that it is possible to identify relationships between different threat actors by analyzing the metadata of malicious LNK files, uncovering information such as the specific tools and techniques used by different groups of cybercriminals, as well as potential links between seemingly unrelated attacks. "With the increasing usage of LNK files in attack chains, it's logical that threat actors have started developing and using tools to create such files," Cisco Talos researcher Guilherme Venere said in a report shared with The Hacker News. This comprises tools like  NativeOne 's  mLNK Builder  and  Quantum Builder , which allow subscribers to generate rogue shortcut files and evade security solutions. Some of the major malware families that have used LNK file

The U.S. Department of Justice (DoJ) on Wednesday announced the arrest of Anatoly Legkodymov (aka Gandalf and Tolik), the cofounder of Hong Kong-registered cryptocurrency exchange Bitzlato, for allegedly processing $700 million in illicit funds. The 40-year-old Russian national, who was arrested in Miami, was charged in a U.S. federal court with "conducting a money transmitting business that transported and transmitted illicit funds and that failed to meet U.S. regulatory safeguards, including anti-money laundering requirements," the DoJ  said . According to court documents, Bitzlato is said to have advertised itself as a virtual currency exchange with minimal identification requirements for its users, breaking the rules requiring the vetting of customers. This lack of know your customer (KYC) enforcement led to the service becoming a "haven for criminal proceeds" and facilitating transactions worth more than $700 million on the Hydra darknet marketplace prior

Identities now transcend human boundaries. Within each line of code and every API call lies a non-human identity. These entities act as programmatic access keys, enabling authentication and facilitating interactions among systems and services, which are essential for every API call, database query, or storage account access. As we depend on multi-factor authentication and passwords to safeguard human identities, a pressing question arises: How do we guarantee the security and integrity of these non-human counterparts? How do we authenticate, authorize, and regulate access for entities devoid of life but crucial for the functioning of critical systems? Let's break it down. The challenge Imagine a cloud-native application as a bustling metropolis of tiny neighborhoods known as microservices, all neatly packed into containers. These microservices function akin to diligent worker bees, each diligently performing its designated task, be it processing data, verifying credentials, or

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

New research has found that it is possible for threat actors to abuse a legitimate feature in GitHub Codespaces to deliver malware to victim systems. GitHub Codespaces  is a cloud-based configurable development environment that allows users to debug, maintain, and commit changes to a given codebase from a web browser or via an integration in Visual Studio Code. It also comes with a port forwarding feature that makes it possible to access a web application that's running on a particular port within the codespace directly from the browser on a local machine for testing and debugging purposes. "You can also forward a port manually, label forwarded ports, share forwarded ports with members of your organization, share forwarded ports publicly, and add forwarded ports to the codespace configuration," GitHub  explains  in its documentation. It's  important  to note here that any forwarded port that's made public will also permit any party with knowledge of the URL

A threat actor by the name  Lolip0p  has uploaded three rogue packages to the Python Package Index (PyPI) repository that are designed to drop malware on compromised developer systems. The packages – named  colorslib  (versions 4.6.11 and 4.6.12),  httpslib  (versions 4.6.9 and 4.6.11), and  libhttps  (version 4.6.12) – by the author between January 7, 2023, and January 12, 2023. They have since been yanked from PyPI but not before they were cumulatively downloaded over 550 times. The modules come with identical setup scripts that are designed to invoke PowerShell and run a malicious binary (" Oxzy.exe ") hosted on Dropbox, Fortinet  disclosed  in a report published last week. The executable, once launched, triggers the retrieval of a next-stage, also a binary named  update.exe , that runs in the Windows temporary folder ("%USER%\AppData\Local\Temp\"). update.exe is flagged by antivirus vendors on VirusTotal as an information stealer that's also capable of

A "large and resilient infrastructure" comprising over 250 domains is being used to distribute information-stealing malware such as  Raccoon  and  Vidar  since early 2020. The infection chain "uses about a hundred of fake cracked software catalogue websites that redirect to several links before downloading the payload hosted on file share platforms, such as GitHub," cybersecurity firm SEKOIA  said  in an analysis published earlier this month. The French cybersecurity company assessed the domains to be operated by a threat actor running a traffic direction system ( TDS ), which allows other cybercriminals to rent the service to distribute their malware. The attacks target users searching for cracked versions of software and games on search engines like Google, surfacing fraudulent websites on top by leveraging a technique called search engine optimization (SEO) poisoning to lure victims into downloading and executing the malicious payloads. The poisoned result

Unidentified threat actors have deployed a new backdoor that borrows its features from the U.S. Central Intelligence Agency (CIA)'s  Hive  multi-platform  malware suite , the source code of which was  released  by WikiLeaks in November 2017. "This is the first time we caught a variant of the CIA Hive attack kit in the wild, and we named it  xdr33  based on its embedded Bot-side certificate CN=xdr33," Qihoo Netlab 360's Alex Turing and Hui Wang  said  in a technical write-up published last week. xdr33 is said to be propagated by exploiting an unspecified N-day security vulnerability in F5 appliances. It communicates with a command-and-control (C2) server using SSL with forged Kaspersky certificates. The intent of the backdoor, per the Chinese cybersecurity firm, is to harvest sensitive information and act as a launchpad for subsequent intrusions. It improves upon Hive by adding new C2 instructions and functionalities, among other implementation changes. The  ELF

DevOps platform CircleCI on Friday disclosed that unidentified threat actors compromised an employee's laptop and leveraged malware to steal their two-factor authentication-backed credentials to breach the company's systems and data last month. The CI/CD service CircleCI said the "sophisticated attack" took place on December 16, 2022, and that the malware went undetected by its antivirus software. "The malware was able to execute session cookie theft, enabling them to impersonate the targeted employee in a remote location and then escalate access to a subset of our production systems," Rob Zuber, CircleCI's chief technology officer,  said  in an incident report. Further analysis of the security lapse revealed that the unauthorized third-party pilfered data from a subset of its databases by abusing the elevated permissions granted to the targeted employee. This included customer environment variables, tokens, and keys. The threat actor is believed t

Tainted VPN installers are being used to deliver a piece of surveillanceware dubbed  EyeSpy  as part of a malware campaign that started in May 2022. It uses "components of SecondEye – a legitimate monitoring application – to spy on users of 20Speed VPN, an Iranian-based VPN service, via trojanized installers," Bitdefender  said  in an analysis. A majority of the infections are said to originate in Iran, with smaller detections in Germany and the U.S., the Romanian cybersecurity firm added. SecondEye, according to  snapshots  captured via the Internet Archive, claims to be a commercial monitoring software that can work as a "parental control system or as an online watchdog." As of November 2021, it's offered for sale anywhere between $99 to $200. It comes with a wide range of features that allows it to take screenshots, record microphone, log keystrokes, gather files and saved passwords from web browsers, and remotely control the machines to run arbitrary c

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

A recent IcedID malware attack enabled the threat actor to compromise the Active Directory domain of an unnamed target less than 24 hours after gaining initial access, while also borrowing techniques from other groups like Conti to meet its goals. "Throughout the attack, the attacker followed a routine of recon commands, credential theft, lateral movement by abusing Windows protocols, and executing Cobalt Strike on the newly compromised host," Cybereason researchers  said  in a report published this week. IcedID , also known by the name BokBot, started its life as a banking trojan in 2017 before evolving into a  dropper for other malware , joining the likes of  Emotet ,  TrickBot ,  Qakbot ,  Bumblebee , and  Raspberry Robin . Attacks involving the delivery of IcedID have  leveraged a variety of methods , especially in the wake of  Microsoft's decision to block macros  from Office files downloaded from the web. The intrusion detailed by Cybereason is no different in

A new analysis of Raspberry Robin's attack infrastructure has  revealed  that it's possible for other threat actors to repurpose the infections for their own malicious activities, making it an even more potent threat. Raspberry Robin (aka QNAP worm), attributed to a threat actor dubbed DEV-0856, is a malware that has  increasingly   come under the radar  for being used in attacks aimed at finance, government, insurance, and telecom entities. Given its use by multiple threat actors to drop a wide range of payloads such as SocGholish , Bumblebee ,  TrueBot ,  IcedID , and  LockBit  ransomware, it's believed to be a pay-per-install (PPI) botnet capable of serving next-stage malware. Raspberry Robin, notably, employs infected USB drives as a propagation mechanism and leverages breached QNAP network-attached storage (NAS) devices as first-level command-and-control (C2). Cybersecurity firm SEKOIA said it was able to identify at least eight virtual private servers (VPSs) hos

A recent wave of Gootkit malware loader attacks has targeted the Australian healthcare sector by leveraging legitimate tools like VLC Media Player. Gootkit , also called Gootloader, is  known  to  employ  search engine optimization (SEO) poisoning tactics (aka spamdexing) for initial access. It typically works by compromising and abusing legitimate infrastructure and seeding those sites with common keywords. Like other malware of its kind, Gootkit is capable of stealing data from the browser, performing adversary-in-the-browser (AitB) attacks, keylogging, taking screenshots, and other malicious actions. Trend Micro's  new findings  reveal that the keywords "hospital," "health," "medical," and "enterprise agreement" have been paired with various city names in Australia, marking the malware's expansion beyond accounting and law firms. The starting point of the cyber assault is to direct users searching for the same keywords to an infe

Government and military organizations in the Asia-Pacific region are being targeted by a previously unknown advanced persistent threat (APT) actor, per latest research conducted by Albert Priego of Group-IB The Singapore-headquartered company, in a  report  shared with The Hacker News, said it's tracking the ongoing campaign under the name  Dark Pink  and attributed seven successful attacks to the adversarial collective between June and December 2022. The bulk of the attacks have singled out military bodies, government ministries and agencies, and religious and non-profit organizations in Cambodia, Indonesia, Malaysia, Philippines, Vietnam, and Bosnia and Herzegovina, with one unsuccessful intrusion reported against an unnamed European state development body based in Vietnam. The threat actor is estimated to have commenced its operations way back in mid-2021, although the attacks ramped up only a year later using a never-before-seen custom toolkit designed to plunder valuable

The first Patch Tuesday fixes shipped by Microsoft for 2023 have addressed a total of  98 security flaws , including one bug that the company said is being actively exploited in the wild. 11 of the 98 issues are rated Critical and 87 are rated Important in severity, with one of the vulnerabilities also listed as publicly known at the time of release. Separately, the Windows maker is expected to release updates for its Chromium-based Edge browser.  The vulnerability that's under attack relates to  CVE-2023-21674  (CVSS score: 8.8), a privilege escalation flaw in Windows Advanced Local Procedure Call ( ALPC ) that could be exploited by an attacker to gain SYSTEM permissions. "This vulnerability could lead to a browser sandbox escape," Microsoft noted in an advisory, crediting Avast researchers Jan Vojtěšek, Milánek, and Przemek Gmerek for reporting the bug. While details of the vulnerability are still under wraps, a successful exploit requires an attacker to have alrea

The advanced persistent threat (APT) group known as  StrongPity  has targeted Android users with a trojanized version of the Telegram app through a fake website that impersonates a video chat service called Shagle . "A copycat website, mimicking the Shagle service, is used to distribute StrongPity's mobile backdoor app," ESET malware researcher Lukáš Štefanko  said  in a technical report. "The app is a modified version of the open source Telegram app, repackaged with StrongPity backdoor code." StrongPity , also known by the names APT-C-41 and Promethium, is a cyberespionage group active since at least 2012, with a majority of its operations focused on Syria and Turkey. The existence of the group was first publicly reported by Kaspersky in October 2016. The threat actor's  campaigns  have since expanded to encompass more targets across Africa, Asia, Europe, and North America, with the intrusions leveraging watering hole attacks and phishing messages to ac
