orvtech··on Teensy 4.1 Development Board
About 7 years ago it was the most affordable USB controller that identify them self as a HID device that I could find to brute force the EFI lock on a MacBook Pro https://orvtech.com/atacar-efi-pin-macbook-pro-en.html

It was really easy to setup and start pushing code to it

orvtech··on Remove default "terraform" partner_id
> ...Going forward, we will be building an option to opt out of using this partner ID...

One should be opted out by default and the option should be build to opt in.

orvtech··on Adobe deactivates all Venezuelan accounts
Agree is not a "Solution" but it does not has the impact that most people are imagining.

I am just curious, what would be the right way for companies to tackle this, how would they know who is the family of a regime official for example? Most people's comments seem to be aimed at Adobe instead of the complexity that is dealing with this executive order.

orvtech··on Adobe deactivates all Venezuelan accounts
Students will still have access to the software via other means as usual, the real impact would be on cloud services I guess
orvtech··on Adobe deactivates all Venezuelan accounts
Yup but lets be hones that does not count for side business (rebuscarse) which is often not declared/measured.

How many of them can actually buy a license with a national average salary of $17 a month?

So, inflation?
orvtech··on Unprotected database exposes sensitive data of over 20M Ecuadoreans
lovely, I wonder how much the company that did this for them charged
orvtech··on DoorDash Changes Tipping Model After Uproar
I'll keep tipping in cash, thank you.
orvtech··on IRS electronic filing system breaks down hours before midnight deadline
It is not the same traffic pattern, Uber sees a regular stream of request keeping their caches warm, Yes they might see 2X or 3X spikes every now and them but in proportion these are smaller than the spikes that the IRS will see today.
orvtech··on Trump Issues Action Blocking Venezuelan Government Cryptocurrencies
As a Venezuelan I welcome these measures. Petro coin would not have helped the people and it was meant to launder money.

Also it is a lie that is backed by PDVSA's oil [1].

orvtech··on Venezuela to Shut Down for a Week to Cope With Electricity Crisis
It is worth to note that Venezuela is an oil producer country that used to sell electricity to Brazil, Guyana and Colombia.
orvtech··on Automated brute-force attack against the EFI PIN (2013)
They did it for the iCloud lock which can be circumvented by automatically rebooting the Mac every X tries.
orvtech··on Automated brute-force attack against the EFI PIN (2013)
I think so. The correct procedure would have been to assign another iCloud account and assign your self another PIN (lock it with your own PIN)... Then reformat it

The buyer tried this but he purchased it from one of his contractors so they did not do anything on writing.
orvtech··on Automated brute-force attack against the EFI PIN (2013)
The message on the first lock screen (iCloud padlock) read "Devuelve me la laptop y te devuelvo el dinero" which means "Give me back the laptop and I will return your money".

I did a low level reformat `dd if=/dev/random of=/dev/sdd` with the hard drive mounted on another machine before noticing that he seller had locked theachine EFI remotely.

Well saw a spike in traffic to my site and traced the source to HN... Let's hope the migration from WordPress to Pelican pays out.

As mentioned by some of you this is from early 2013 but the code still works. Furthermore it has been tweaked (the timeouts and keypress duration) to be compatible with most Macs yet as efficient as possible.

I also did an iCloud Padlock version http://orvtech.com/ataque-fuerza-bruta-pin-icloud-en.html but it takes way longer.

I am working on a version that using a Raspberry Pi + Arduino should work on any BIOS, EFI, OR PIN lock for that matter.

orvtech··on Google DNS servers suffer brief traffic hijack
Leaving politics and ideology aside, there are precedents to consider... back in 2012 Malaysia had a similar situation but the outage was wider and more pronounced.

A different precedent is the fact that phishing sites for social networks have been found on Venezuela's government-operated ISP servers not that long a go http://orvtech.com/en/general/gobierno-venezolano-elecciones...

orvtech··on Feedly Found a New Way to Steal Page Views From Publishers
go on... I mean do we know their IPs? they could easily move to amazon and not provide any distinguishable Browser ID, etc..

This might take more time than my previous Teensy project "Attacking the EFI PIN Lock" but I do understand that there are people that don't want to lose the content of their hard drive so this mechanism might work for them.
orvtech··on Alienware X51 Gaming PC with Ubuntu OS available
TBH I would pay full price. I just want to have a laptop that comes with linux out of factory.

PD: off-topic, I am tempted to get a cheap chromebook and install linux on it. I am currently researching

orvtech··on Alienware X51 Gaming PC with Ubuntu OS available
Now all we need are ultrabooks with linux
orvtech··on WordPress.com is down
yeah, it failed for mee too a couple of times. I also got an error from Facebook twice. Probably one of their carriers or a CND issue

less talky talky more coding, I will supply coffee

This is awesome! now lets get some sweet Tux Racer or Mario Kart going! (please?)
orvtech··on Automated brute-force attack against iCloud PIN Lock with this Arduino sketch
This is the same Arduino sketch I used to brute-force the EFI Lock but I have implemented a set of conditional loops to wait the 1, 5 and 15 minutes cycles that the iCloud Lock PIN implements. I still use the Teensy 3 for automate this attack which gets done with minimal intervention, just plug it and thats it.

This is specially useful for those who dont have an apple store nearby or those who just dont want to deal with "The Geniuses".

orvtech··on A failed bruteforce attack on the EFI PIN lock of a MacBook Pro
Initially I though this lock resided on the disk only, specially since it had a nice UI. I thought "this cant be the bios"
orvtech··on A failed bruteforce attack on the EFI PIN lock of a MacBook Pro
It is a link of this chains of bad decisions but I did not wanted the information to be recovered in any way.

Testdisk managed to recover most information except that some part of the GPT were corrupted.
