UPD Download Dangerous RAT Exe
Cisco Talos assesses with moderate to high confidence these attacks have been conducted by the North Korean state-sponsored threat actor Lazarus Group. This attribution is based on tactics, techniques and procedures (TTPs), malware implants and infrastructure overlap with known Lazarus campaigns.We have observed overlaps in C2 servers serving MagicRAT and previously disclosed Lazarus campaigns utilizing the Dtrack RAT family. Furthermore, Talos has also discovered C2 servers hosting and serving TigerRAT to existing MagicRAT infections. TigerRAT is a malware family attributed to the Lazarus APT groups by the Korean Internet & Security Agency (KISA).In some infections, we observed the deployment of MagicRAT by the attackers for some time, followed by its removal and the subsequent download and execution of another custom-developed malware called "VSingle," another implant disclosed and attributed to Lazarus by JPCERT.

One of the C2 servers used by the new MagicRAT sample, 64[.]188[.]27[.]73, hosted two more distinct implants masquerading as GIF URLs. Now, MagicRAT can make requests to its C2 and download a GIF file, which is actually an executable.
The second implant hosted on MagicRAT's C2 is a remote access trojan (RAT) known as TigerRAT. TigerRAT is an implant disclosed in 2021 by KISA and KRCERT as part of "Operation ByteTiger'' detailing TigerRAT and its downloader "TigerDownloader."This implant consists of several RAT capabilities, ranging from arbitrary command execution to file management. Capabilities of the implant include:

Microsoft releases the MSRT on a monthly cadence as part of Windows Update or as a standalone tool. Use this tool to find and remove specific prevalent threats and reverse the changes they have made (see covered malware families). For comprehensive malware detection and removal, consider using Windows Defender Offline or Microsoft Safety Scanner.This article contains information about how the tool differs from an antivirus or antimalware product, how you can download and run the tool, what happens when the tool finds malware, and tool release information. It also includes information for the administrators and advanced users, including information about supported command-line switches.
A5: No. The Microsoft Knowledge Base article number for the tool will remain as 890830 for future versions of the tool. The file name of the tool when it is downloaded from the Microsoft Download Center will change with each release to reflect the month and the year when that version of the tool was released.
A12: When you are first offered the Malicious Software Removal Tool from Microsoft Update, Windows Update, or Automatic Updates, you can decline downloading and running the tool by declining the license terms. This action can apply to only the current version of the tool or to both the current version of the tool and any future versions, depending on the options that you choose. If you have already accepted the license terms and prefer not to install the tool through Windows Update, clear the checkbox that corresponds to the tool in the Windows Update UI.
A13: If it is downloaded from Microsoft Update or from Windows Update, the tool runs only one time each month. To manually run the tool multiple times a month, download the tool from the Download Center or by visiting the Microsoft Safety & Security Center website.For an online scan of your system by using the Windows Live OneCare safety scanner, go to the Microsoft Safety Scanner website.
After we reported this to Pastebin, the source page has been taken down.SummaryA dropper we analyzed downloaded the code for part of its payload from Pastebin on the fly. The payload turned out to be a RAT with keylogging capabilities.
Using Edge Chromium ver. 88.0.705.68 when trying to download a filename.jlnp file from a server inside our organization we are prompted with the following message. Is there a way to stop this message from coming up and downloading the automatically?
I had this problem and downloaded Chrome browser which worked without a problem. Chrome did ask me whether I wished to download a potentially unsafe file which I had arranged in MS Access and downloaded previously without the problem I experienced using Edge. I completed the task in 5 minutes.
You can enable this policy to create a dictionary of file type extensions with a corresponding list of domains that will be exempted from file type extension-based download warnings. This lets enterprise administrators block file type extension-based download warnings for files that are associated with a listed domain.
For example, if the "jnlp" extension is associated with "website1.com", users would not see a warning when downloading "jnlp" files from "website1.com", but see a download warning when downloading "jnlp" files from "website2.com".
The first injected script will direct the user to click.clickanalytics208[.]com to download the fake update template. If it fails to meet the attacker's checkpoints, such as geolocation and network settings, then it will execute the next injected script.
The fake template page will display an alert to try to trick the user into starting the update. Once the user clicks the "Update" button, the script downloads the malicious HTA file from the specified URL.
If the user clicks the "Later" button, the redirect still occurs, taking the user to the same page to download the malicious HTA file. The following figure depicts the source code of the template.js with the link to download the malicious HTA file with the banner value 3.
Recording and/or obtaining stills (i.e. screenshots) of the screen is also a feature of this type of malware. RATs can often exfiltrate (download) data stored on the system and some can infiltrate (upload) it. If malicious software is capable of infiltrating files and executing them, this can cause chain infections (i.e. download/installation of additional malware).
As well as the capability of downloading stored content, remote access Trojans commonly have other features geared specifically towards stealing information. Keylogging (i.e. recording of key strokes) is common functionality, and the capability to extract saved/stored log-in credentials (i.e. IDs, usernames and passwords) from browsers and other applications.
The primary malware distribution techniques include spam campaigns, illegal activation tools ("cracks"), bogus updates and dubious download channels. Spam campaigns are operations during which deceptive/scam emails are sent on a mass scale.
Fake updaters cause infections by abusing flaws of outdated products and/or simply installing malicious programs rather than the promised updates. Malware is often downloaded inadvertently from untrusted sources such as unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders.
Use official and verified download channels. It is also important to activate and update products with tools/functions provided by legitimate developers. Illegal activation ("cracking") tools and third party updaters must not be used, as they often proliferate malicious software.
A RAT (remote access Trojan) is malware an attacker uses to gain full administrative privileges and remote control of a target computer. RATs are often downloaded along with seemingly legitimate user-requested programs -- such as video games -- or are sent to their target as an email attachment via a phishing email.
A RAT can also be installed through phishing emails, download packages, web links or torrent files. Users are duped into downloading malicious files through social engineering tactics, or the RAT is installed by threat actors after they gain physical access to a victim's machine, such as through an evil maid attack.
Unlike other cybersecurity threat vectors, RATs are dangerous even after they've been removed from a system. They can modify files and hard drives, change data, and record user passwords and codes through keylogging and screen captures, all of which can have long-lasting effects. 041b061a72
