Malware-as-a-Service | Breaking Cybersecurity News | The Hacker News

A multinational law enforcement operation has resulted in the takedown of an online cybercrime syndicate that offered services to threat actors to ensure that their malicious software stayed undetected from security software. To that effect, the U.S. Department of Justice (DoJ) said it seized four domains and their associated server facilitated the crypting service on May 27, 2025, in partnership with Dutch and Finnish authorities. These include AvCheck[.]net, Cryptor[.]biz, Cryptor[.]live, and Crypt[.]guru, all of which now display a seizure notice. Other countries that participated in the effort include France, Germany, Denmark, Portugal, and Ukraine. "Crypting is the process of using software to make malware difficult for antivirus programs to detect," the DoJ said . "The seized domains offered services to cybercriminals, including counter-antivirus (CAV) tools. When used together, CAV and crypting services allow criminals to obfuscate malware, making it undetecta...

The threat actors known as Golden Chickens have been attributed to two new malware families dubbed TerraStealerV2 and TerraLogger, suggesting continued development efforts to fine-tune and diversify their arsenal. "TerraStealerV2 is designed to collect browser credentials, cryptocurrency wallet data, and browser extension information," Recorded Future Insikt Group said . "TerraLogger, by contrast, is a standalone keylogger. It uses a common low-level keyboard hook to record keystrokes and writes the logs to local files." Golden Chickens, also known as TA4557 and Venom Spider, is the name given to a financially motivated threat actor linked to a notorious malware family called More_eggs . It's known to be active since at least 2018, offering its warez under a malware-as-a-service (MaaS) model. Campaigns distributing More_eggs entail the use of spear-phishing emails to target hiring managers using fake resumes, allowing attackers to steal confidential data. ...

Cybersecurity researchers are calling attention to a new malware campaign that leverages fake CAPTCHA verification checks to deliver the infamous Lumma information stealer. "The campaign is global, with Netskope Threat Labs tracking victims targeted in Argentina, Colombia, the United States, the Philippines, and other countries around the world," Leandro Fróes, senior threat research engineer at Netskope Threat Labs, said in a report shared with The Hacker News. "The campaign also spans multiple industries, including healthcare, banking, and marketing, with the telecom industry having the highest number of organizations targeted." The attack chain begins when a victim visits a compromised website, which directs them to a bogus CAPTCHA page that specifically instructs the site visitor to copy and paste a command into the Run prompt in Windows that uses the native mshta.exe binary to download and execute an HTA file from a remote server. It's worth noting...

Detecting leaked credentials is only half the battle. The real challenge—and often the neglected half of the equation—is what happens after detection. New research from GitGuardian's State of Secrets Sprawl 2025 report reveals a disturbing trend: the vast majority of exposed company secrets discovered in public repositories remain valid for years after detection, creating an expanding attack surface that many organizations are failing to address. According to GitGuardian's analysis of exposed secrets across public GitHub repositories, an alarming percentage of credentials detected as far back as 2022 remain valid today: "Detecting a leaked secret is just the first step," says GitGuardian's research team. "The true challenge lies in swift remediation." Why Exposed Secrets Remain Valid This persistent validity suggests two troubling possibilities: either organizations are unaware their credentials have been exposed (a security visibility problem),...

A spear-phishing email campaign has been observed targeting recruiters with a JavaScript backdoor called More_eggs, indicating persistent efforts to single out the sector under the guise of fake job applications. "A sophisticated spear-phishing lure tricked a recruitment officer into downloading and executing a malicious file disguised as a resume, leading to a more_eggs backdoor infection," Trend Micro researchers Ryan Soliven, Maria Emreen Viray, and Fe Cureg said in an analysis. More_eggs, sold as a malware-as-a-service (MaaS), is a malicious software that comes with capabilities to siphon credentials, including those related to online bank accounts, email accounts, and IT administrator accounts. It's attributed to a threat actor called the Golden Chickens group (aka Venom Spider), and has been put to use by several other e-crime groups like FIN6 (aka ITG08 ), Cobalt, and Evilnum. Earlier this June, eSentire disclosed details of a similar attack that leverages ...

Cybersecurity researchers have discovered a new version of an Android banking trojan called Octo that comes with improved capabilities to conduct device takeover ( DTO ) and perform fraudulent transactions. The new version has been codenamed Octo2 by the malware author, Dutch security firm ThreatFabric said in a report shared with The Hacker News, adding campaigns distributing the malware have been spotted in European countries like Italy, Poland, Moldova, and Hungary. "The malware developers took actions to increase the stability of the remote actions capabilities needed for Device Takeover attacks," the company said . Some of the malicious apps containing Octo2 are listed below - Europe Enterprise (com.xsusb_restore3) Google Chrome (com.havirtual06numberresources) NordVPN (com.handedfastee5) Octo was first flagged by the company in early 2022, describing it as the work of a threat actor who goes by the online aliases Architect and goodluck. It has been assessed...

Cybersecurity researchers have uncovered a never-before-seen dropper that serves as a conduit to launch next-stage malware with the ultimate goal of infecting Windows systems with information stealers and loaders. "This memory-only dropper decrypts and executes a PowerShell-based downloader," Google-owned Mandiant said . "This PowerShell-based downloader is being tracked as PEAKLIGHT." Some of the malware strains distributed using this technique are Lumma Stealer , Hijack Loader (aka DOILoader, IDAT Loader, or SHADOWLADDER), and CryptBot , all of which are advertised under the malware-as-a-service (SaaS) model. The starting point of the attack chain is a Windows shortcut (LNK) file that's downloaded via drive-by download techniques -- e.g., when users look up a movie on search engines. It's worth pointing out that the LNK files are distributed within ZIP archives that are disguised as pirated movies. The LNK file connects to a content delivery network...

Cybersecurity researchers have uncovered a new information stealer that's designed to target Apple macOS hosts and harvest a wide range of information, underscoring how threat actors are increasingly setting their sights on the operating system. Dubbed Cthulhu Stealer, the malware has been available under a malware-as-a-service (MaaS) model for $500 a month from late 2023. It's capable of targeting both x86_64 and Arm architectures. "Cthulhu Stealer is an Apple disk image (DMG) that is bundled with two binaries, depending on the architecture," Cado Security researcher Tara Gould said . "The malware is written in Golang and disguises itself as legitimate software." Some of the software programs it impersonates include CleanMyMac, Grand Theft Auto IV, and Adobe GenP, the last of which is an open-source tool that patches Adobe apps to bypass the Creative Cloud service and activates them without a serial key. Users who end up launching the unsigned file af...

The nascent malware known as SSLoad is being delivered by means of a previously undocumented loader called PhantomLoader, according to findings from cybersecurity firm Intezer. "The loader is added to a legitimate DLL, usually EDR or AV products, by binary patching the file and employing self-modifying techniques to evade detection," security researchers Nicole Fishbein and Ryan Robinson said in a report published this week. SSLoad, likely offered to other threat actors under a Malware-as-a-Service (MaaS) model owing to its different delivery methods, infiltrates systems through phishing emails, conducts reconnaissance, and pushes additional types of malware down to victims. Prior reporting from Palo Alto Networks Unit 42 and Securonix has revealed the use of SSLoad to deploy Cobalt Strike, a legitimate adversary simulation software often used for post-exploitation purposes. The malware has been detected since April 2024. The attack chains typically involve the use o...

Cybersecurity researchers have spotted a phishing attack distributing the More_eggs malware by masquerading it as a resume, a technique originally detected more than two years ago. The attack, which was unsuccessful, targeted an unnamed company in the industrial services industry in May 2024, Canadian cybersecurity firm eSentire disclosed last week. "Specifically, the targeted individual was a recruiter that was deceived by the threat actor into thinking they were a job applicant and lured them to their website to download the loader," it said. More_eggs, believed to be the work of a threat actor known as the Golden Chickens (aka Venom Spider), is a modular backdoor that's capable of harvesting sensitive information. It's offered to other criminal actors under a Malware-as-a-Service (MaaS) model. Last year, eSentire unmasked the real-world identities of two individuals – Chuck from Montreal and Jack – who are said to be running the operation. The latest atta...

Cybersecurity researchers have discovered a malicious Python package uploaded to the Python Package Index (PyPI) repository that's designed to deliver an information stealer called Lumma (aka LummaC2). The package in question is crytic-compilers, a typosquatted version of a legitimate library named crytic-compile . The rogue package was downloaded 441 times before it was taken down by PyPI maintainers. "The counterfeit library is interesting in that, in addition [to] being named after the legitimate Python utility, 'crytic-compile,' it aligns its version numbers with the real library," Sonatype security researcher Ax Sharma said . "Whereas the real library's latest version stops at 0.3.7, the counterfeit 'crytic-compilers' version picks up right here, and ends at 0.3.11 — giving off the impression that this is a newer version of the component." In a further attempt to keep up the ruse, some versions of crytic-compilers (e.g., 0.3.9) we...

Cyber attacks involving the DarkGate malware-as-a-service (MaaS) operation have shifted away from AutoIt scripts to an AutoHotkey mechanism to deliver the last stages, underscoring continued efforts on the part of the threat actors to continuously stay ahead of the detection curve. The updates have been observed in version 6 of DarkGate released in March 2024 by its developer RastaFarEye, who has been selling the program on a subscription basis to as many as 30 customers. The malware has been active since at least 2018. A fully-featured remote access trojan (RAT), DarkGate is equipped with command-and-control (C2) and rootkit capabilities, and incorporates various modules for credential theft, keylogging, screen capturing, and remote desktop. "DarkGate campaigns tend to adapt really fast, modifying different components to try to stay off security solutions," Trellix security researcher Ernesto Fernández Provecho said in a Monday analysis. "This is the first time...

Cybersecurity researchers have detected a new wave of phishing attacks that aim to deliver an ever-evolving information stealer referred to as  StrelaStealer . The campaigns impact more than 100 organizations in the E.U. and the U.S., Palo Alto Networks Unit 42 researchers said in a new report published today. "These campaigns come in the form of spam emails with attachments that eventually launch the StrelaStealer's DLL payload," researchers Benjamin Chang, Goutam Tripathy, Pranay Kumar Chhaparwal, Anmol Maurya, and Vishwa Thothathri said . "In an attempt to evade detection, attackers change the initial email attachment file format from one campaign to the next, to prevent detection from the previously generated signature or patterns." First disclosed in November 2022, StrelaStealer is  equipped  to siphon email login data from well-known email clients and exfiltrate them to an attacker-controlled server. Since then, two large-scale campaigns involving the ma...

Cybersecurity researchers have discovered an updated variant of a stealer and malware loader called  BunnyLoader  that modularizes its various functions as well as allow it to evade detection. "BunnyLoader is dynamically developing malware with the capability to steal information, credentials and cryptocurrency, as well as deliver additional malware to its victims," Palo Alto Networks Unit 42  said  in a report published last week. The new version, dubbed BunnyLoader 3.0, was announced by its developer named Player (or Player_Bunny) on February 11, 2024, with rewritten modules for data theft, reduced payload size, and enhanced keylogging capabilities. BunnyLoader was  first documented  by Zscaler ThreatLabz in September 2023, describing it as a malware-as-a-service (MaaS) designed to harvest credentials and facilitate cryptocurrency theft. It was initially offered on a subscription basis for $250 per month. The malware has since undergone frequent upd...

Information stealing malware are actively taking advantage of an undocumented Google OAuth endpoint named MultiLogin to hijack user sessions and allow continuous access to Google services even after a password reset. According to CloudSEK, the  critical exploit  facilitates session persistence and cookie generation, enabling threat actors to maintain access to a valid session in an unauthorized manner. The technique was first revealed by a threat actor named PRISMA on October 20, 2023, on their Telegram channel. It has since been  incorporated  into  various malware-as-a-service (MaaS) stealer families , such as Lumma, Rhadamanthys, Stealc, Meduza, RisePro, and WhiteSnake. The MultiLogin authentication endpoint is primarily designed for synchronizing Google accounts across services when users sign in to their accounts in the Chrome web browser (i.e.,  profiles ).  A reverse engineering of the Lumma Stealer code has revealed that the technique tar...

A new malware loader is being used by threat actors to deliver a wide range of  information stealers  such as Lumma Stealer (aka LummaC2), Vidar, RecordBreaker (aka Raccoon Stealer V2), and  Rescoms . Cybersecurity firm ESET is tracking the trojan under the name  Win/TrojanDownloader.Rugmi . "This malware is a loader with three types of components: a downloader that downloads an encrypted payload, a loader that runs the payload from internal resources, and another loader that runs the payload from an external file on the disk," the company  said  in its Threat Report H2 2023. Telemetry data gathered by the company shows that detections for the Rugmi loader spiked in October and November 2023, surging from single digit daily numbers to hundreds per day. Stealer malware is typically sold under a malware-as-a-service (MaaS) model to other threat actors on a subscription basis. Lumma Stealer, for instance, is advertised in underground forums for $250 a mo...
