The problem is that EDR monitors these interfaces through hooks in user mode and calls in the kernel, so the researcher developed a new technique that completely bypasses these two interfaces
The new mechanism
When you type commands in a terminal window for a program like nslookup.exe, this data is stored in the program's memory itself through a named pipe specifically for standard input (hStdInput)
Creating a child process (such as nslookup.exe or netsh.exe) and obtaining its input pipe handle.
Writing malicious code by calling WriteFile on the pipe – the bytes are transferred to the target process's memory without ever calling WriteProcessMemory
Locating the code A unique byte sequence (marker) is added at the beginning of the payload to facilitate its search within the target process's memory
This is the best

VLC 2026 — Two New Memory-Corruption Vulnerabilities
CVE-2026-56711 — PNG Integer Overflow → Heap Out-of-Bounds Write
Affected 3.0.0 – 3.0.23
Type Integer Overflow / Heap
Out-of-Bounds Write
CWE CWE-190 + CWE-787
CVSS 3.1 8.8 HIGH
CVSS 4.0 8.6 HIGH
Trigger Malicious PNG
User interaction Required
The vulnerability was published on September 9, 2026.
The interesting part is that the bug is not simply "PNG parsing is broken."
The problem occurs when VLC calculates how much memory is required to store an image.
Conceptually, VLC needs something like:
required_memory =
bytes_per_line × number_of_lines
For example:
pitch = 4000 bytes
lines = 3000
4000 × 3000
= 12,000,000 bytes
Everything is normal.
The problem appears when attacker-controlled image dimensions become extremely large.
The Integer Overflow
The relevant VLC code uses integer values for parts of the picture structure.
The vulnerable calculation is essentially:
i_bytes += p->i_pitch * p->i_lines;
The important detail is that the multiplication can happen using 32-bit integer arithmetic.
A simplified example
2,000,000,000
×
2
=
4,000,000,000
But a signed 32-bit integer cannot represent that value normally.
The result can wrap around:
4,000,000,000
↓
32-bit integer overflow
↓
negative/small wrapped value
The allocation logic can therefore believe that it needs a relatively small amount of memory when the decoder later works with the much larger dimensions

Your LG TV is eavesdropping on you. It transcribes what you say, copies what is on your screen, and scans every device on your network, and researchers say the collection keeps running after you disconnect it, uploading the moment it reconnect to the internet.
Researchers advise disconnecting LG TVs from any network.

So far, I see Windows as nothing special anymore; it can only be used as a testing ground. Do you agree?
Another thing is that Ubuntu has also become a competitor to Windows in terms of system resource consumption.
