A new malware loader identified as HijackLoader is getting traction amid the cybercriminal local community to supply various payloads these types of as DanaBot, SystemBC, and RedLine Stealer.
“Even even though HijackLoader does not consist of innovative options, it is able of working with a selection of modules for code injection and execution given that it utilizes a modular architecture, a function that most loaders do not have,” Zscaler ThreatLabz researcher Nikolaos Pantazopoulos said.
1st noticed by the business in July 2023, the malware employs a range of approaches to fly beneath the radar. This requires making use of syscalls to evade monitoring from security options, checking processes associated with security program based on an embedded blocklist, and placing off code execution by as a great deal as 40 seconds at different stages.
The exact preliminary entry vector made use of to infiltrate targets is at present not known. The anti-analysis features notwithstanding, the loader packs in a most important instrumentation module that facilitates versatile code injection and execution utilizing embedded modules.
Persistence on the compromised host is obtained by making a shortcut file (LNK) in the Windows Startup folder and pointing it to a Qualifications Smart Transfer Company (BITS) occupation.
“HijackLoader is a modular loader with evasion strategies, which provides a variety of loading solutions for malicious payloads,” Pantazopoulos explained. “What’s more, it does not have any sophisticated functions and the quality of the code is very poor.”
The disclosure will come as Flashpoint disclosed particulars of an current edition of an information and facts-stealing malware recognised as RisePro that was beforehand dispersed by using a pay-for every-set up (PPI) malware downloader service dubbed PrivateLoader.
“The vendor claimed in their advertisements that they have taken the finest facets of ‘RedLine’ and ‘Vidar’ to make a strong stealer,” Flashpoint noted. “And this time, the vendor also guarantees a new advantage for people of RisePro: buyers host their have panels to guarantee logs are not stolen by the sellers.”
RisePro, created in C++, is built to harvest delicate information and facts on contaminated equipment and exfiltrate it to a command-and-command (C&C) server in the type of logs. It was to start with provided for sale in December 2022.
It also follows the discovery of a new information and facts stealer written in Node.js which is packaged into an executable and dispersed by means of destructive Big Language Model (LLM)-themed Facebook adverts and bogus web-sites impersonating ByteDance’s CapCut video clip editor.
“When the stealer is executed, it operates its main function that steals cookies and qualifications from numerous Chromium-based web browsers, then exfiltrates the information to the C&C server and to the Telegram bot,” security researcher Jaromir Horejsi mentioned.
“It also subscribes the shopper to the C&C server working GraphQL. When the C&C server sends a information to the client, the stealing function will run once more.” Specific browsers include things like Google Chrome, Microsoft Edge, Opera (and OperaGX), and Courageous.

This is the second time phony CapCut websites have been noticed delivering stealer malware. In May perhaps 2023, Cyble uncovered two various attack chains that leveraged the software as a entice to trick unsuspecting end users into running Offx Stealer and RedLine Stealer.
The developments paint a photograph of a regularly evolving cybercrime ecosystem, with stealer bacterial infections acting as a primary initial attack vector employed by threat actors to infiltrate companies and carry out write-up-exploitation actions.
It can be for that reason not astonishing that danger actors are jumping on the bandwagon to spawn new stealer malware strains this sort of as Prysmax that include a Swiss Army knife of functionalities that permit their customers to optimize their get to and impression.
“The Python-based mostly malware is packed making use of Pyinstaller, which can be made use of to bundle the malicious code and all its dependencies into a solitary executable,” Cyfirma claimed. “The information stealing malware is focused on disabling Windows Defender, manipulating its settings, and configuring its personal response to threats.”
“It also attempts to minimize its traceability and keep a foothold on the compromised process. The malware appears to be perfectly-developed for data theft and exfiltration, while evading detection by security equipment as perfectly as dynamic evaluation sandboxes.”
