Krypte Ransomware

Krypte is an updated version of Razy ransomware. Once infiltrated, Krypte encrypts victim's files using asymmetric cryptography. While encrypting, Krypte renames compromised files using "10_random_letters_and_digits.fear" pattern (e.g., "sample.jpg" will be renamed to something like "bGw20AaNJa.fear"). Following successful encryption, Krypte displays a pop-up window with a ransom-demanding message. The message is written in German, which means that Krypte targets users from Germany. It is stated that victim's files can only be restored by using a unique decrypter. In order to receive this tool, victims must send Krypte's developers 15-20 EUR worth of paysafecard code. Victim must also provide one's email address, to which the decryption tool will then be sent. It is worth mentioning that Krypte's ransom is quite small comparing to other ransomware - other viruses of this type dema...

How to remove “Your device has been blocked” ransomware virus from Android tablet or phone?

Cyber criminals have been spreading ransomware viruses on Windows-based computers for some time. These types of infections became popular in mid-2006 and continue to infect personal computers and extort money from their victims. Recently, security research began showing a rise in Android-based mobile ransomware infections. Commonly, ransomware viruses exploit the names of authorities including the FBI, USA Cyber Crime Investigations, and The ICE Cyber Crime Center - making fake claims that users must pay an amount of money (for supposed law violations such as watching pornography, using copyrighted files, etc.) in order to unblock their devices. In most cases, cyber criminals employ the Green Dot MoneyPak, Ukash, or PaySafeCard pre-paid card services to collect fake fines from unsuspecting mobile device users. Tablet and mobile phone users should be aware that paying these fines as ordered by these messages ...

Cambridge University Hacks iPhone 5c that FBI Says Could Not be Hacked

Cambridge University researcher Sergei Skorobogatov demonstrated that he can brute force attack the passcode screen lock feature on the iPhone 5c. He did this by physically opening up the iPhone and then making a copy of the memory chip which he then connected to the phone using wires. Then he said you could enter every 4 digit passcode from 0001 to 1111 manually until you unlocked the phone. He did not actually do that as it would take 20 hours. Instead he proved it would work. The goal was to use copies of the memory chip, because if the security feature is enabled the iPhone erases the memory after 6 failed attempts. The paper he wrote explaining the process is here. And a YouTube video of him demonstrating the procedure is here. The FBI wanted to try this type of attack against iPhone owned the San Bernardino terrorists. The FBI director said, “It did not work.” Then they paid a security firm $1.3 million fo...
