DUHK Attack Lets Hackers Recover Encryption Key Used in VPNs & Web Sessions

DUHK Attack Lets Hackers Recover Encryption Key Used in VPNs & Web Sessions

October 24, 2017Mohit Kumar
DUHK — Don't Use Hard-coded Keys — is a new 'non-trivial' cryptographic implementation vulnerability that could allow attackers to recover encryption keys that secure VPN connections and web browsing sessions. DUHK is the third crypto-related vulnerability reported this month after KRACK Wi-Fi attack and ROCA factorization attack . The vulnerability affects products from dozens of vendors, including Fortinet , Cisco, TechGuard, whose devices rely on ANSI X9.31 RNG — an outdated pseudorandom number generation algorithm — 'in conjunction with a hard-coded seed key.' Before getting removed from the list of FIPS-approved pseudorandom number generation algorithms in January 2016, ANSI X9.31 RNG was included into various cryptographic standards over the last three decades. Pseudorandom number generators (PRNGs) don't generate random numbers at all. Instead, it is a deterministic algorithm that produces a sequence of bits based on initial secret values called a

NIST Removes Dual_EC_DRBG Random Number Generator from Recommendations

The National Institute of Standards and Technology (NIST) has announced to abandon the controversial  Dual Elliptic Curve Deterministic  Random Bit Generator,  better known as  Dual_EC_DRBG in the wake of allegations that the National Security Agency. Back in December, Edward Snowden leaks revealed that RSA received $10 million bribe from NSA under a secret contract to implement their flawed cryptographic algorithm Dual_EC_DRBG in its bSafe Security tool as the default protocol in its products for keeping Encryption Weak . In response to the accusations on NSA and RSA, and despite RSA denied all the accusations. without wasting time NIST issued an announcement recommending against using Dual_EC_DRBG and abandon the cryptographic algorithm from its revised guidance provided in the Recommendation for Random Number Generation Using Deterministic Random Bit Generators ( NIST Special Publication 800-90A, Rev.1 ). But it didn't remove it from its random number generator

According to media reports in September, documents released by whistleblower Edward Snowden have confirmed the existence of backdoor in some technologies RSA . Last Friday, The Reuters News Agency accused the Security firm RSA for taking a $10 million ' bribe ' from the National Security Agency ( NSA ) in order promote a flawed encryption by including it in its BSAFE product to facilitate NSA spying . Today In a blog post , RSA has categorically denied accusation about any secret partnership with the National Security Agency to insert backdoor. " Recent press coverage has asserted that RSA entered into a "secret contract" with the NSA to incorporate a known flawed random number generator into its BSAFE encryption libraries. We categorically deny this allegation. " " We have never entered into any contract or engaged in any project with the intention of weakening RSA's products " the company said. The company gave the following reasons for choosing and promoting
NSA paid $10 Million bribe to RSA Security for Keeping Encryption Weak

NSA paid $10 Million bribe to RSA Security for Keeping Encryption Weak

If you own a world-renowned Security Product or a Service, National Security Agency (NSA) is ready to pay you 10 Million or more bribe for keeping intentional backdoor for them. According to an exclusive report published by Reuters , there is a secret deal between the NSA and respected encryption company RSA to implement a flawed security standard as the default protocol in its products. Earlier Edward Snowden leaks had revealed that the NSA created a flawed random number generation system (Dual_EC_DRBG), Dual Elliptic Curve , which RSA used in its Bsafe security tool and now Snowden has revealed that RSA received $10 million from NSA for keeping Encryption Weak. So, anyone who knows the right numbers used in Random number generator program, can decipher the resulting cryptotext easily. Recommending bad cryptographic standard is one thing, but accepting 10 million to deliberately implement is something very shameful for a respected Security company. The new revelation is impor
