So we all know that you can calculate an approximate location of every cell phone by looking at the signal strength each phone has to any towers in range. Now I wonder if it would technically be possible to have a smart phone that only con… Continue reading Can you prevent triangulation tracking by only connecting to one cell tower? [closed]
I was quite shocked today to see that a Windows 10 Pro machine that I recently set up with BitLocker (startup PIN + TPM with full disk encryption) suddenly didn’t have BitLocker enabled anymore:
And apparently Windows mess… Continue reading How to prevent Windows Update from suspending BitLocker encrytion?
I have a pretty simple question about KRACK.
From what I have read it would be very common to be able to forge, decrypt, delay and block client packets as well as AP packets using KRACK.
Does this mean that an attacker co… Continue reading Can KRACK be used to obtain wifi credentials that could be used to normally connect to an AP?
I have a bunch of Android devices for which there either is no patch to protect them against the BlueBorne exploit or I cannot install a patch without losing all the data.
The most obvious thing would be to disable BlueToo… Continue reading How do I protect my old devices against BlueBorne?

From what I understand pretty much all Intel CPUs produced since Sandy-Bridge have “secret” 3G capabilities in their IME (Intel Management Engine). This IME has full access to the memory bus and pretty much your whole computer and there is… Continue reading Privacy implications of Intel CPU’s secret 3G communication (Anti Theft 3.0)
I have an NFC/RFID keychain that looks pretty much like this one:
When I read it with an Android app called “Nfc Reader”, it shows me a specific ID (always the same) and it says that these technologies are used: IsoDep, NfcA, NdefFormat… Continue reading Is it possible to clone an NFC/RFID chip that uses IsoDep, NfcA and NdefFormatable
Someone recently told me that the NSA could impersonate pretty much anyone they want by using IP address spoofing on the Internet.
But how would that work and to what extend is it true anyway?
Could any ISP in the world just spoof any IP … Continue reading How does IP address spoofing on the Internet work? Who can do it?
Let’s say we have a WPA2-PSK secured AP and there are several clients like smartphones and notebooks that automatically connect to it.
Now if someone was to create another AP that looked completely the same from the outside (same channel, … Continue reading How does WPA2-PSK prevent evil twin password phishing?
Would it be possible for other people to use my PPPoE data to get Internet access or is it somehow restricted to my house? Then what about my neighbors downstairs, could they do it?
And what about intercepting a PPPoE login? Are PPPoE logi… Continue reading Could other people steal my Internet connection if they had my PPPoE data?
