A recent report from Google's Threat Intelligence team indicates:

• This attack on WinRAR began as early as July 18, 2025, and has not stopped since
• The attackers include both state-sponsored espionage organizations and low-level cybercriminals driven by financial interests

Hacker attacks typically employ the following chain:

1. Malicious files are hidden within compressed archives, for example, using Alternate Data Streaming (ADS) technology
2. These archives are disguised as normal files, containing decoy content and a hidden malicious payload
3. The vulnerability is triggered when a user opens or extracts these archives using WinRAR
4. WinRAR, during path traversal, extracts the hidden malicious payload to an arbitrary location
5. The generated malicious files typically include LINK, HTA, BAT, CMD, or other script files
6. These script files are written to the system's startup directory or critical locations and execute upon system startup when the user logs in

Google's threat intelligence team observed several active hacking groups, including but not limited to:

• UNC4895
• APT44
• Turla

In addition, some hacking groups with financial interests are exploiting this vulnerability to:

• Distribute malware
• Steal sensitive user information
• Distribute backdoor programs controlled by Telegram bots
• Install malicious browser extensions to steal banking information

The report notes that these hackers appear to obtain exploits from specialized vulnerability vendors. For example:

• A vendor codenamed ZeroPlayer advertised an exploit targeting WinRAR in July 2025

Google researchers commented that this commoditization of exploit development reflects a trend in the cyberattack lifecycle: the commoditization of exploits lowers the barrier and complexity for attackers to launch attacks, making any unpatched system vulnerable to attack in a short period of time.

In the face of ongoing attacks, do not take chances:

The biggest feature of this version is: Letting Win7 install and run normally on modern hardware.

It includes:

• ✅ All historical security update patches
• ✅ USB 3 driver support
• ✅ NVMe SSD support
• ✅ Modern network card drivers
• ✅ 35 system languages (including Simplified/Traditional Chinese)

Problems many people encountered when installing Win7 in the past, such as unresponsive keyboard/mouse, inability to recognize NVMe SSDs, unavailable USB3 interfaces, this version has already integrated these in advance.

Many people are shocked at first glance:

• Original Win7: About 3.1GB
• Ultimate Win7: About 11.87GB

The volume directly tripled.

The reason is actually simple: The author pre-installed a large number of system language packs, supporting 35 languages in total, including Simplified Chinese, Traditional Chinese, English, Japanese, etc. If you don't need so many languages, you can delete them yourself after system installation to free up space.

1. Network Disk Download: Click to go
2. Torrent Download: Click to get

1. System USB Creation: Click to download (recommend USB drive at least 12G+)
2. Virtual Machine Installation: Click to download Can install Windows 7 on Windows or Mac systems

Additional Tools:

• VMware 17.0 Pro: Official Download
• VMware Fusion 13 Pro: Download
• Manjaro 21.3 Ruah: Click to go

Regarding security, it's also what everyone cares about most.

The author explained the production method in the project, using the old system packaging tool to reintegrate patches and drivers, rather than the arbitrarily modified "third-party simplified version."

That is to say: If you're worried about security issues, you can actually follow the author's method to package a Win7 Ultimate image yourself.

This way you have higher controllability and more peace of mind.

To be honest, in 2026, Windows 7 is no longer suitable as a main system.

The truly valuable scenarios are mainly:

• ✅ Nostalgia and Ancient Games: Like CS1.6, Red Alert, old single-player games, old online game clients,反而 more stable on Win7.
• ✅ Compatible with Old Software: Some industrial software, financial software, old plugins only support Win7 environment.
• ✅ Commercial Old Equipment: Industrial control computers, testing equipment, cash register systems - such equipment "don't replace if not broken."
• ✅ Tinker Players: Pure experience, collection, testing system.

If you want to use it for video editing, running AI, making modern development environments, it's basically unrealistic. Browser, driver, and API support for Win7 is getting less and less.

Windows 7, for many people, is not just a system, but a memory.

But the reality is also clear: It has already exited the mainstream stage.

This "most ultimate Win7" is more like:

• Leaving a way out for nostalgic players
• Extending the life of old equipment
• Giving tinkerers a toy

Rather than a solution for ordinary users to use long-term.

We need to prepare an Indian VPN, this is an essential prerequisite. Click here to install free Indian node VPN. Of course, to increase availability, it's recommended to use paid VPN Click here to get Surfshark.

They both have mobile apps, direct installation is more convenient!

After switching to Indian IP, then enter ChatGPT official website, you can register a new account, or use an old account (Foo IT Zone uses an old account).

After entering, you can see free trial ChatGPT for 12 months at the top, you can see "Free Gift" or "Activate Plus" prompt, click to see the following page:

Choose GO meal, original price is 399 rupees but now it's 0 rupees,说明 you can enjoy this 1-year discount package. If you don't see the above page, it means your IP address is not pure enough, or your ChatGPT is a new account,建议 changing account to try. It's recommended to use UnionPay credit card,建议 using your real card (doesn't need to be Indian), also no need to switch regions, activate directly!

To avoid being cancelled like before, using it for a few days and then GO membership gets cancelled, so a stable Indian node VPN is essential. Whether you're on PC or mobile, when using ChatGPT GO paid account, always keep the Indian node VPN connected. Free is certainly nice, but unstable, so you can choose paid VPN, need to have Indian nodes, such as Surfshark or ProtonVPN both are available! They both have mobile apps, direct installation is more convenient!

Or you can be like me, have a permanent free Oracle Cloud Server, then deploy OpenVPN or WireGuard inside, you can permanently get a free Indian proxy node.

wget https://git.io/vpn -O openvpn-install.sh && bash openvpn-install.sh

In OCI console, add to Network Security Group (NSG) or Security List:

• Protocol: UDP
• Port: 51820
• Source: 0.0.0.0/0

Or directly open all ports to save trouble each time!

Open all ports:

iptables -P INPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -P OUTPUT ACCEPT
iptables -F

Ubuntu mirror sets iptables rules by default, disable it:

apt-get purge netfilter-persistent
reboot

Or force delete:

rm -rf /etc/iptables && reboot

Or install WireGuard, security encryption is better, suitable for special users:

Ubuntu / Debian:

apt update
apt install -y wireguard qrencode

wg genkey | tee server_private.key | wg pubkey > server_public.key
wg genkey | tee client_private.key | wg pubkey > client_public.key

View public keys:

cat server_public.key
cat client_public.key

View private keys:

cat server_private.key
cat client_private.key

Create configuration file:

sudo nano /etc/wireguard/wg0.conf

Note: Modify the network card inside: eth0 (everyone's is different). eth0 might not be your network card name, you can use ip a to check (OCI is usually ens3 or enp0s3).

If it's ens3, please change all eth0 above to ens3.

sudo nano /etc/sysctl.conf

Uncomment or add:

net.ipv4.ip_forward=1

Then execute:

sudo sysctl -p

sudo systemctl enable wg-quick@wg0
sudo systemctl start wg-quick@wg0

Revolutionary 3D Visual Reconstruction System

SAM 3D is a 3D visual reconstruction system that Meta has upgraded based on its classic Segment Anything Model (SAM). It's not simply about "identifying objects from images," but rather directly reconstructing usable 3D models, poses, and spatial structures from a single image or video.

Two Main Components

SAM 3D Body: Focuses on 3D pose, motion, skeleton, and mesh reconstruction of the human body
SAM 3D Objects: Used to recreate various objects in the real world, such as furniture, tools, and electronic products

🛍️ AR Shopping: Bringing Products "Into Your Home"

Merchants upload product photos → SAM 3D generates 3D models → You open AR on your phone → Place it directly in your living room. This upgrades e-commerce from "ordering based on images" to "ordering after a real preview."

🏥 Medical and Rehabilitation: AI Understands Your Every Move

SAM 3D Body can reconstruct human skeleton from video, identify joint angles, and analyze movement standards. AI acts like a "virtual therapist," monitoring movement correctness in real time for improved rehabilitation accuracy.

SAM 3D Body: Transformer Architecture

Meta uses a 3D pose regression system based on a Transformer encoder-decoder architecture. Input: Ordinary image → Output: 3D human body mesh + pose parameters. It doesn't predict keypoints, but directly predicts the complete 3D human body model.
