Malware in the form of Windows 11 upgrade tool
Hackers use malicious Windows 11
upgrade software to infect users
Browse
digital currencies and wallets. Microsoft has provided an upgrade tool for its
users to check their system with this tool to see if it can be installed.
Windows 11 is available to them or not. One of the requirements of the system is the Trusted Platform Module (TPM) version 2.0. Hackers put fake site addresses in search results and users who do not research and check reputable sites,
Aiming to
install Windows 11.Fake site with a look like a Microsoft site
Windows 11-upgrade 11 [.] com Fake site with address
By visiting
this site and clicking on Download Now, users will receive an ISO file
containing malware.
The download process will not run if a VPN or TOR is used.Infection process
According to CloudSEK, the threat actors behind the campaign are using new malware that researchers have. Using the Inno Setup Windows installer was called "Inno Stealer".To be honest, no code similarities were found with other examples of data theft programs currently in use, and no evidence of malware uploading was found on the Total Virus scanning platform.
In the first step, the loader file written in Delphi language is called Windows 11 setup inside the ISO, which by executing it creates a temporary file called is-PN131.tmp and another .TMP file that the loader writes 3,078 KB of data. The loader also uses Create Process to create new processes that help the Persist, create new processes, and extract 4 more files.
The Persist process is performed by adding the .LNK shortcut file to the Startup folder and specifying access permissions using icacls.exe.Two of the four extracted files are Windows Command Scripts to disable security
Registry, add exceptions to Defender, delete security products and remove shadow volume.
According to the researchers, the malware removes the security products of Emsisoft and ESET, probably because these products detect it as malicious.
The third file is a command execution tool that runs with the highest system scores. And the fourth file is the VBA script to run dfl.cmd.
In the
second stage of infection, a file with the extension .SCR is placed in the
following path:
C:\Users\\AppData\Roaming\Windows11InstallationAssistant
This file is
used to unpack and execute the main program upload by creating a process called
Windows11InstallationAssistant.scr
is done.
Malware capabilities
Malware capabilities are the same as malware in its category, such as browser data theft, cookie theft, wallet information theft, digital passwords and clipboard theft, etc.
The
following are the browsers and wallets targeted in this campaign:

One of the interesting features of Inno Stealer is that it has multi-threaded network management and data theft functions.All data stolen through PowerShell is copied and encrypted into the user's temporary directory and then sent to C&C ("windows-server031.com")
The process of communicating with the C2 server
These
Delphi-based uploads, which are sent as TXT files, use the same INNO loader
mechanism.
Security solution. The Windows 11 upgrade process has paved the way for the spread of malware campaigns, and this is not the first time this has been reported.
It is recommended to avoid downloading ISO files from obscure sources and only do the main operating system upgrades from within your Windows 10 control panel or download the installation files directly from the source.
If an upgrade to Windows 11 is not available to you, trying to circumvent the restrictions manually is useless, as this will come with a host of downsides and serious security risks.
Ransomware Gang black cat attack organizations
Ransomware gang has attacked at least 60 organizations globally as of
March. BlackCat, also known as ALPHV, is a relatively new group of
cybercriminals that operates a Windows ransomware-as-a-service. But while it
only appeared on the ransomware crime scene in November 2021, security
researchers and federal law enforcement have linked its developers and money
launderers.
To the notorious Darkside/Blackmatter crime rings, "indicating they have extensive networks and experience with ransomware operations," security researchers at Cisco Talos and Palo Alto Networks Unit 42 also noted BlackCat preference for Rust, with Unit 42 saying the gang was "one of the first, if not the first" of its kind to use this programming language. The fact that the gang writes its ransomware in Rust, as opposed to C/C++, is interesting. Rust arguably has crucial safety measures built in, That meaning the malware could be more stable and reliable.
Like C/C++ toolchains, the Rust environment can be used to build programs for embedded devices, and integrate with other programming languages, said Attivo Networks Chief Security Advocate Carolyn Crandall. The alert also includes BlackCat indicators of compromise and warns the ransomware typically leverages previously compromised user credentials to gain access to a victim's system. "Initial deployment of the malware leverages PowerShell scripts, in conjunction with Cobalt Strike, and disables security features within the victim's network," After breaking in, the malware compromises Active Directory user and administrator accounts, and it uses Windows Task Scheduler to configure malicious group policy objects to deploy ransomware. But before it executes the ransomware, BlackCat steals a victim's data, including

Vulnerable products are used in an organization hacked
When outdated and vulnerable products are used in an organization, the way to penetrate that organization will be open.
In the broadcast images, it can be seen that Windows 7 is installed on Evin prison systems. Windows that went out of business a year and a half ago and support has stopped. If other equipment is not managed and updated in this way, experts know that it will not be difficult to penetrate this system!
A year and a half ago here the necessary warning was repeatedly given and it was said that from today every Windows 7 is a vulnerability in the organization.
Hackers group have leaked security camera footage from inside Iran's notorious Evin prison showing the brutal treatment of inmates. The surveillance video shows inmates fighting, being hit by guards and dragged along the floor, and in one scene smashing a bathroom mirror in an attempt to use the glass to self-harm. One clip shows the hacker group taking control of monitors in the prison control room, flashing a message stating Evin prison is a stain of shame on Raisi's black turban and white beard" and calling for "nationwide protests to release political prisoners.
Ebrahim Raisi, the new president of Iran, is a hardline cleric who is subject to US sanctions for alleged human rights abuses, with accusations against him including presiding over a torture regime in Evin prison and ordering mass executions. His victory means hardliners will have full control over all branches of government in Iran for the first time in almost a decade, after ultra-conservatives took a majority in last year's parliamentary elections.
In a tweet on Tuesday, the head of Iran's prison organisation, Mahammad Mehdi Has Mohammadi, confirmed the authenticity of the leaked security camera footage. Accepting responsibility for the "unacceptable behaviour", Mr Mohammadi committed to dealing seriously with the offenders and, according to a translation by Al Jazeera, wrote:
I also apologise to God, our dear supreme leader, the great nation and the honourable prison guards, whose efforts will certainly not be ignored due to these errors." Evin prison is notorious for hosting political prisoners, including many dual-nationals and citizens of Western countries, including Nazanin Zaghari-Ratcliffe and Kylie Moore-Gilbert.

Nepal's cyber security why weaknesses point
Nepal's cyber
security why weaknesses point
A few
weeks ago, about two thousand government websites were hacked after four hours
closed. Question has been raised in Nepal's cyber security.
Experts believe that the hackers attack on the server of national information technology centering of government agencies websites showed a weak state of cyber security.
They said
that the incident is large and threatening the national security in the future,
will not increase its lessons. Officials say that after the incident adopting
more vigilance for cyber security, government officials.
Due to
weakness of cyber security, the lack of necessary policy and action plan, lack
of investment in security and lack of regular safety test is the main three reasons.
Ø Predecessor required
According to
Cyber Security Advisor Saroj Lamichenne, the government should formulate
policy and method for dealing with such incidents.
Lamichhane
says: "To avoid such threats, it is necessary to set a definite period and
plan cyber security with priority."
He suggested
that the criteria for purchase equipment of information technology used in
government bodies should be made.
In the event
of increasing the use of technology globally, Nepal also needs to formulate
timely policy.
"Cyber
assault for Nepal cannot be seen as a major subject in the instantaneous
situation, even if it is not serious about such issues, it may have to face a
major risk at once," he added.
Ø Low investment in security
Vice President of Computer Association Nepal (CAN)
Federation, Sunnah Pandey said that due to government depression, the country
could not invest in information technology sector because the country could not
progress relatively well about cyber security.
He said that the government has started keeping
important personal details such as citizenship and driver's permission on
websites, and said that there could be no higher cost in the future, if not to
invest immediately in that area.
Pandey says, "The website seems to be justified
after leaving the website now. Information may be stolen at the time of the
website running.
He has experienced two or three teams to secure the
server in other countries.
"A team is working to attack the server in a new
way and another team will resist it so that it can be done immediately after
the attack is attacked."
He said that the government wants to save the software
from cyber-attack in Nepal.
Ø Security alert
Based on the needs of the government, based on a
certain type of software, rather than using a website by using the website,
then officials say successful hackers are able to attack the same number.
Information Officer of National Information Technology
Center, Ramesh Prasad Pokharel told BBC Nepali service, "It has started
using non-software software to minimize such incidents - it will likely reduce
the potential to hack in future."
According to him, the recent hack did China and India
hackers, and it affected the flow of service to various important bodies.
The release issued by the Center was stated that
government service was blocked in the official domain name server (gov.np
DNS) due to the huge traffic coming from abroad in the Government Unified
Data Center.
Pokharel says: "Such conditions have also been
made repeatedly, even if there is no definite criterion or policy about making
important things like government agencies websites. “There is no security test
to continue at that time."
Ø Policy arrangements
Although cyber assault through the internet cannot be
stopped, it can be said that Rosa Kiran Basukula, deputy director of the Nepal
Telecommunication Authority, was made rapidly by speeding the process of making
necessary policy rules.
Bacukala says: "We have presented the documents
regarding cyber security policy in collaboration with the International
Telecommunications Association before the government."
He said that it is important to safeguard the website
and discourage cybercrimes if the payment for online banking and internet is
accelerating.
