Beware! YouTube Videos Promoting Cracked Software Distribute Lumma Stealer

Beware! YouTube Videos Promoting Cracked Software Distribute Lumma Stealer
Jan 09, 2024 Malware / Cyber Threat
Threat actors are resorting to YouTube videos featuring content related to cracked software in order to entice users into downloading an information stealer malware called Lumma. "These YouTube videos typically feature content related to cracked applications, presenting users with similar installation guides and incorporating malicious URLs often shortened using services like TinyURL and Cuttly," Fortinet FortiGuard Labs researcher Cara Lin  said  in a Monday analysis. This is not the first time pirated software videos on YouTube have emerged as an effective bait for stealer malware. At least since early 2023, similar attack chains have been observed delivering several kinds of stealers, clippers, and crypto miner malware. In doing so, threat actors can leverage the compromised machines for not only information and cryptocurrency theft, but also abuse the resources for illicit mining. In the latest attack sequence documented by Fortinet, users searching for cracked versions of

Oct 20, 2023 Cyber Threat / Malware
A new information stealer named  ExelaStealer  has become the latest entrant to an already  crowded landscape  filled with various off-the-shelf malware designed to capture sensitive data from compromised Windows systems. "ExelaStealer is a largely open-source infostealer with paid customizations available from the threat actor," Fortinet FortiGuard Labs researcher James Slaughter  said  in a technical report. Written in Python and incorporating support for JavaScript, it comes fitted with capabilities to siphon passwords, Discord tokens, credit cards, cookies and session data, keystrokes, screenshots, and clipboard content. ExelaStealer is offered for sale via cybercrime forums as well as a dedicated Telegram channel set up by its operators who go by the online alias quicaxd. The paid-for version costs $20 a month, $45 for three months, or $120 for a lifetime license. The low cost of the commodity malware makes it a perfect hacking tool for newbies, effectively lowerin

Timing is Everything: The Role of Just-in-Time Privileged Access in Security Evolution

Timing is Everything: The Role of Just-in-Time Privileged Access in Security Evolution
Apr 15, 2024Active Directory / Attack Surface
To minimize the risk of privilege misuse, a trend in the privileged access management (PAM) solution market involves implementing just-in-time (JIT) privileged access. This approach to  privileged identity management  aims to mitigate the risks associated with prolonged high-level access by granting privileges temporarily and only when necessary, rather than providing users with continuous high-level privileges. By adopting this strategy, organizations can enhance security, minimize the window of opportunity for potential attackers and ensure that users access privileged resources only when necessary.  What is JIT and why is it important?   JIT privileged access provisioning  involves granting privileged access to users on a temporary basis, aligning with the concept of least privilege. This principle provides users with only the minimum level of access required to perform their tasks, and only for the amount of time required to do so. One of the key advantages of JIT provisioning

Evasive Meduza Stealer Targets 19 Password Managers and 76 Crypto Wallets

Evasive Meduza Stealer Targets 19 Password Managers and 76 Crypto Wallets
Jul 03, 2023 Malware / Hacking
In yet another sign of a lucrative crimeware-as-a-service ( CaaS ) ecosystem, cybersecurity researchers have discovered a new Windows-based information stealer called  Meduza Stealer  that's actively being developed by its author to evade detection by software solutions. "The Meduza Stealer has a singular objective: comprehensive data theft," Uptycs  said  in a new report. "It pilfers users' browsing activities, extracting a wide array of browser-related data." "From critical login credentials to the valuable record of browsing history and meticulously curated bookmarks, no digital artifact is safe. Even crypto wallet extensions, password managers, and 2FA extensions are vulnerable." Despite the similarity in features, Meduza boasts of a "crafty" operational design that eschews the use of obfuscation techniques and promptly terminates its execution on compromised hosts should a connection to the attacker's server fail. It's

Newly Uncovered ThirdEye Windows-Based Malware Steals Sensitive Data

Newly Uncovered ThirdEye Windows-Based Malware Steals Sensitive Data
Jun 29, 2023 Cyber Threat / Hacking
A previously undocumented Windows-based information stealer called  ThirdEye  has been discovered in the wild with capabilities to harvest sensitive data from infected hosts. Fortinet FortiGuard Labs, which  made the discovery , said it found the malware in an executable that masqueraded as a  PDF file  with a Russian name "CMK Правила оформления больничных листов.pdf.exe," which translates to "CMK Rules for issuing sick leaves.pdf.exe." The arrival vector for the malware is presently unknown, although the nature of the lure points to it being used in a phishing campaign. The very  first ThirdEye sample  was uploaded to VirusTotal on April 4, 2023, with relatively fewer features. The evolving stealer, like  other malware families  of its kind, is equipped to gather system metadata, including BIOS release date and vendor, total/free disk space on the C drive, currently running processes, register usernames, and volume information. The amassed details are then tra

Russian Hackers Using Graphiron Malware to Steal Data from Ukraine

Russian Hackers Using Graphiron Malware to Steal Data from Ukraine
Feb 08, 2023 Threat Intelligence / Data Safety
A Russia-linked threat actor has been observed deploying a new information-stealing malware in cyber attacks targeting Ukraine. Dubbed Graphiron by Broadcom-owned Symantec, the malware is the handiwork of an espionage group known as  Nodaria , which is tracked by the Computer Emergency Response Team of Ukraine (CERT-UA) as UAC-0056. "The malware is written in Go and is designed to harvest a wide range of information from the infected computer, including system information, credentials, screenshots, and files," the Symantec Threat Hunter Team  said  in a report shared with The Hacker News. Nodaria was  first spotlighted  by CERT-UA in January 2022, calling attention to the adversary's use of  SaintBot and OutSteel malware  in spear-phishing attacks targeting government entities. Also called DEV-0586, TA471, and UNC2589, the hacking crew has been linked to the destructive WhisperGate (aka PAYWIPE ) data wiper attacks targeting Ukrainian entities around the same time.

The Evolving Tactics of Vidar Stealer: From Phishing Emails to Social Media

The Evolving Tactics of Vidar Stealer: From Phishing Emails to Social Media
Jan 05, 2023 Data Security / Malware
The notorious information-stealer known as  Vidar  is continuing to leverage popular social media services such as TikTok, Telegram, Steam, and Mastodon as an intermediate command-and-control (C2) server. "When a user creates an account on an online platform, a unique account page that can be accessed by anyone is generated," AhnLab Security Emergency Response Center (ASEC) disclosed in a technical analysis  published  late last month. "Threat actors write identifying characters and the C2 address in parts of this page." In other words, the technique relies on actor-controlled throwaway accounts created on social media to retrieve the C2 address. An advantage to this approach is that should the C2 server be taken down or blocked, the adversary can trivially get around the restrictions by setting up a new server and editing the account pages to allow the previously distributed malware to communicate with the server. Vidar, first identified in 2018, is a  commer

Haskers Gang Gives Away ZingoStealer Malware to Other Cybercriminals for Free

Haskers Gang Gives Away ZingoStealer Malware to Other Cybercriminals for Free
Apr 15, 2022
A crimeware-related threat actor known as Haskers Gang has released an  information-stealing malware  called ZingoStealer for free on, allowing other criminal groups to leverage the tool for nefarious purposes. "It features the ability to steal sensitive information from victims and can download additional malware to infected systems," Cisco Talos researchers Edmund Brumaghin and Vanja Svajcer  said  in a report shared with The Hacker News. "In many cases, this includes the  RedLine Stealer  and an XMRig-based cryptocurrency mining malware that is internally referred to as 'ZingoMiner.'" But in an interesting twist, the criminal group announced on Thursday that the ownership of the ZingoStealer project is changing hands to a new threat actor, in addition to offering to sell the source code for a negotiable price of $500. Since its inception last month, ZingoStealer is said to be undergoing consistent development and deployed specifically against Russi

Solarmarker InfoStealer Malware Once Again Making its Way Into the Wild

Solarmarker InfoStealer Malware Once Again Making its Way Into the Wild
Aug 02, 2021
Healthcare and education sectors are the frequent targets of a new surge in credential harvesting activity from what's a "highly modular" .NET-based information stealer and keylogger, charting the course for the threat actor's continued evolution while simultaneously remaining under the radar. Dubbed " Solarmarker ," the malware campaign is believed to be active since September 2020, with telemetry data pointing to malicious actions as early as April 2020, according to Cisco Talos. "At its core, the Solarmarker campaign appears to be conducted by a fairly sophisticated actor largely focused on credential and residual information theft," Talos researchers Andrew Windsor and Chris Neal  said  in a technical write-up published last week. Infections consist of multiple moving parts, chief among them being a .NET assembly module that serves as a system profiler and staging ground on the victim host for command-and-control (C2) communications and fur
