In 2017, rumors started to circulate that Grayshift had created a device able to unlock iPhones, following the Apple–FBI encryption dispute where US law enforcement agencies unsuccessfully tried to compel Apple to write software that would enable the government bypass these devices' security and unlock the phones.
Electronic locks are not vulnerable to traditional manipulation techniques (except for brute-force entry). These locks are often compromised through power analysis attacks. [12] [13] Several tools exist that can automatically retrieve or reset the combination of an electronic lock; notably, the Little Black Box [14] and Phoenix. Tools like ...
A major security flaw was revealed in December 2011 that affects wireless routers with the WPS PIN feature, which most recent models have enabled by default. The flaw allows a remote attacker to recover the WPS PIN in a few hours with a brute-force attack and, with the WPS PIN, the network's WPA/WPA2 pre-shared key (PSK). [3]
A brute-force attack is a cryptanalytic attack that can, in theory, be used to attempt to decrypt any encrypted data (except for data encrypted in an information-theoretically secure manner). [1] Such an attack might be used when it is not possible to take advantage of other weaknesses in an encryption system (if any exist) that would make the ...
In cryptanalysis and computer security, password cracking is the process of guessing passwords [1] protecting a computer system.A common approach (brute-force attack) is to repeatedly try guesses for the password and to check them against an available cryptographic hash of the password. [2]
PINs are not only susceptible to smudge attacks but other attacks possible through direct observation like shoulder-surfing attacks or just pure guessing like brute-force attacks. They are also used heavily in electronic transactions or for using ATMs and other banking situations. If a PIN is shared or stolen, the device or machine cannot ...
Key stretching also improves security in some real-world applications where the key length has been constrained, by mimicking a longer key length from the perspective of a brute-force attacker. [1] There are several ways to perform key stretching. One way is to apply a cryptographic hash function or a block cipher repeatedly in a loop.
The flaw allows a remote attacker to recover the WPS PIN and, with it, the router's WPA/WPA2 password in a few hours. [45] Users have been urged to turn off the WPS feature, [46] although this may not be possible on some router models. Also, the PIN is written on a label on most Wi-Fi routers with WPS, which cannot be changed if compromised.
