WorldWind Stealer Pro

Telling facts is fundamental WorldWind Stealer Pro to cybercriminals nowadays to scope and gain get right of entry to systems, profile agencies, and execute larger payday schemes like ransomware.

Information stealer malware families such as WorldWind Stealer Pro:

Configured via a builder to facilitate the method for much less state-of-the-art dangerous actors. but, Zscaler ThreatLabz researchers have exposed the WorldWind Stealer Pro builder, also attributed with WorldWind, and DarkEye, which has a secret backdoor within the code that ends up in each derivative reproduction and version of these malware households. The backdoor sends copies of victims’ exfiltrated records accumulated via other risk actors to a non-public Telegram chat monitored by means of the builder’s builders.

While this untrustworthy behavior is not anything WorldWind Stealer Pro:

New in the global of cybercrime, the sufferers’ statistics emerge as in the hands of a couple of threat actors, increasing the risks of 1 or greater huge-scale assaults to follow.

WorldWind Stealer Pro is a statistics stealer that has the ability to capture credentials that are stored on a compromised machine which includes web browsers, VPN/FTP clients, as well as messaging and gaming applications.

WorldWind Stealer Pro is a noticeably new information stealer malware family that is written in .net. The malware has previously been analyzed in intensity along with the data harvesting capabilities and the targeted programs. Zscaler ThreatLabz has considered uncovering additional details about the malware including the codebase being derived from as a minimum other open supply malware households: AsyncRAT and StormKitty. This blog will awareness of these shared codebases, the changes brought with the aid of the WorldWind Stealer Pro writer (consisting of a backdoor), and the very close dating with WorldWind and DarkEye.


WorldWind Stealer Pro  is not simply stimulated from open-source malware families, however, shares code that looks to have been directly replica and pasted from those repositories. Many components of the Prynt Stealer code which have been borrowed from other malware households aren’t used, however, are nonetheless present in the binary as useless unreachable code. The Prynt Stealer code is generally derived from AsyncRAT (a versatile RAT) and StormKitty (a records stealer). The AsyncRAT code is used as the main module with a modified entry factor that calls the StormKitty stealer technique. Prynt Stealer executables have configured the usage of a builder that has no options to regulate the embedded AsyncRAT additives, that are pre-configured frequently just to run the StormKitty stealer module. most of AsyncRAT’s capability in Prynt Stealer is disabled and the command-and-manipulate (C&C) URLs are configured to while the AsyncRAT’s network thing of Prynt Stealer is disabled, the malware consists of the subsequently embedded certificates shown beneath:


notice that the not-unusual call for this certificate is WorldWind Stealer, which is also sold via the WorldWind Stealer Pro malware author.


The WorldWind Stealer Pro writer added two new fields (highlighted in determine 1) to the AsyncRAT configuration codebase for facts exfiltration via Telegram.

the primary code chargeable for sending records to Telegram is copied from StormKitty with a few minor modifications in the text as shown in determine 2.

the main distinction is the sphere names and order have been modified, and a discipline related to detecting porn websites is lacking from Prynt.


A detailed take look at WorldWind Stealer Pro modifications:

Prynt Stealer does not use the anti-evaluation code from both AsyncRAT or StormKitty with one exception: the malware creates a thread that invokes the feature named processChecker (shown in determine 3) in AsyncRAT’s static constructor. The thread execution is started on the give up of the principle function after stolen logs are despatched.

WorldWind Stealer Pro uses this thread to constantly display the victim’s manner list. If any of the subsequent procedures are detected, the malware will block the Telegram C&C conversation channels:

WorldWind Stealer Pro creates a thread as a way to ballot for a file to download the usage of the Telegram getUpdates API as proven in parent four. Of word, this download command best saves the report on the target gadget and does now not take any in additional movements that are probably predicted like executing a 2nd-level payload or updating the malware.

The WorldWind Stealer Pro logs are despatched to the operator’s Telegram. however, there may be a trap: a duplicate of the log files is likewise sent to a Telegram chat probably embedded through the Prynt Stealer creator as shown in Figure 6.

ThreatLabz has determined comparable processes employed by means of malware authors inside the past as nicely, in which the malware has been given away without spending a dime. This permits a malware writer to gain from unsuspecting cybercriminal customers who carry out the heavy lifting of infecting victims. The reality that every one WorldWind Stealer Pro samples encountered via ThreatLabz had the equally embedded telegram channel implies that this backdoor channel became deliberately planted with the aid of the author. interestingly, the Prynt Stealer author isn’t the best at charging a few customers for the malware but also receives all the records that is stolen. notice that there are cracked/leaked copies of Prynt Stealer with an equal backdoor, which in turn will benefit the malware creator even without direct reimbursement.


ThreatLabz has identified at least two extra WorldWind Stealer Pro variants dubbed WorldWind and DarkEye that appear like written by means of the equal creator. All three traces are nearly equal with some minor differences. Prynt Stealer is the maximum famous logo call for promoting the malware, whilst WorldWind payloads are the most commonly determined in the wild. DarkEye isn’t always sold or cited publicly, however, it’s miles bundled as a backdoor with an “unfastened” Prynt Stealer builder. figure 7 indicates a pie chart of the share of samples through names discovered via ThreatLabz during the last year.

The downloaded payload is DarkEye Stealer, a variant of WorldWind Stealer Probased on a hardcoded Telegram token shared by means of DarkEye, Prynt and WorldWind stealer, they are all probable from the identical writer(s).


DarkEye Stealer
This malware is largely WorldWind Stealer Pro with a few minor variations in code placement. most settings associated with the clipper, keylogger, and many others are moved underneath the AsyncRAT constructor as shown in Figure 14.

the principle component differentiating DarkEye from Prynt and Worldwind is that the AsyncRAT a part of the code is weaponized by configuring the related settings. observe that there have been a few earlier variations of DarkEye stealer in the wild with out the AsyncRAT additives.

Loda RAT is an Autoit-based RAT first documented in 2017 that has been lively seeing that and has developed over the years. this is a reasonably successful malware that can steal a spread of records, remotely manipulate an inflamed system and install extra payloads.


The unfastened availability of source code for numerous malware families has made improvement simpler than ever for much less sophisticated risk actors. As a result, there had been many new malware households created over time which are based totally on popular open-source malware projects like NjRat, AsyncRAT, and QuasarRAT. The WorldWind Stealer Procreator went a step in addition and delivered a backdoor to steal from their clients by way of hardcoding a Telegram token and chat identification into the malware. This tactic isn’t always new through any approach; there were numerous similar times, inclusive of CobianRAT. because the saying is going, there’s no honor amongst WorldWind Stealer Pro.
