New hacker exploit found

New vulnerability, called DUHK (Don’t use hard-coded keys) puts login credentials of cryptoexchange users at risk

Researchers at the University of Pennsylvania and Johns Hopkins University have discovered a new vulnerability that could be used to compromise encryption keys of websites. In a potential this vulnerability also puts in risk the registration data of users of cryptoexchanges. This is reported by the BitsOnline.

The vulnerability, which was called DUHK (Do not use hard-coded keys), was discovered by cryptographers Nadia Henninger, Shaan Koni and Matthew Green. Its source is called ANSI X9.31 RNG, a pseudo-random number generation algorithm (PRNG) that has been used in numerous online products for the last 30 years, including the creation of encryption keys for VPN connections and browser sessions containing credentials, payment information and other information.

As the researchers found that when hardware and software products use ANSI X9.31 and a hard-coded seed key, the attacker has the ability to decrypt data passing through a vulnerable device.

Also, the fault lies with the manufacturers, who often use the hard-coded seed key for ANSI X9.31. In normal circumstances, the seed key must be generated randomly each time the device starts or ANSI X9.31 itself.

In January 2016, the Federal Information Processing Standard (FIPS), the agency responsible for developing computer security standards in the US, removed ANSI X9.31 RNG from its lists, citing as one of the reasons non-encryption-resistant encryption.

As the researchers say, before attacks DUHK FortiOS is vulnerable from version 4.3.0 to 4.3.18, There are more than 23,000 devices in the network on the network. FortiOS 5.x is not affected, while seed key from FortiOS code 4.3.19 has already been cleaned.

Researchers also note that although the DUHK attack is not so easy to implement, it is more than possible to apply it in practice. So, using DUHK, a modern computer is able to pick up the main encryption key in just four minutes.

The situation is complicated by the fact that Fortinet is not the only vulnerable producer. In their report, the specialists presented a list of products using ANSI X9.31 and hard-coded seed key. The list, in particular, includes solutions from Cisco and TechGuard.

The vulnerability is not aimed directly at users of crypto-exchange exchanges, but can be used by hackers to manipulate output to compromise encryption keys and use them to gain access to confidential user information, including registration data, bank account details, etc.

Raven Protocol to be the First IDO at Binance DEX

Team cannot say exactly how IEO will pass, since similar campaigns hadn't been concluded at Binance DEX before, but they are going to sell $500k worth tokens

The Raven Protocol cryptocurrency project announced about the planned initial exchange offering (IEO), which will be based on the infrastructure of the Binance DEX exchange - in this case the campaign will be called IDO or Initial Dex Offering.

Raven Protocol confirmed the right to list its token on Binance DEX paired with BNB on June 17 at 9:00 UTC. At the same time, the IDO of RAVEN tokens will start. The project draws attention to the fact that neither Binance, nor Binance Chain, nor Binance DEX stand behind this initiative.

At the same time, Raven Protocol notes that it cannot say how exactly IEO will pass, since with Binance DEX, similar campaigns have not been conducted before.

Potential participants need to pass a preliminary identification by sending to the address of founders@ravenprotocol.com their address in the Binance Chain, an identity document, a selfie and proof of residence.

In total, Raven Protocol expects to raise $ 500,000 by selling 3% of its own token emission (300,000,000 RAVEN). Accommodation will be on a first come, first served basis. The limit on the amount of investment for one user is declared at the level of 100 BNB.
