Bluetooth: Your smartphone (and wallet?) can be tracked!

 


Smartphone locations can be tracked using broadcast Bluetooth signals. However, recent research also shows that it is not trivial.


A group of researchers from the University of San Diego in California has shown that smartphones, and therefore people, can be tracked via Bluetooth. The identification of the smartphone is possible because a chipset is installed during production, which received a physical fingerprint during production. In order to be able to carry out the attack, a so-called software defined radio sniffer is required. These radio receivers can record raw signals. The attack is possible because every smartphone emits so-called Bluetooth Low Energy beacons. These signals are sent continuously and are used, for example, for contact tracing. During manufacture, these beacons and Wi-Fi are integrated into the same chip. Since Wi-Fi requires a unique identification of the device,


However, in the practical implementation of the attack, some challenges arise. The clear identification not only depends on the built-in chipset in the smartphone to be tracked, but also on the devices in the immediate vicinity. The different transmission powers of Android smartphones and iPhones, the temperature of the devices and the quality of the radio signals are also important. The researchers found that some devices have a very specific fingerprint and are therefore easy to identify. Other smartphones, on the other hand, use a very similar fingerprint and are therefore difficult to identify, especially in busy environments. Bluetooth therefore poses a fundamental threat to location tracking. However, it is extremely difficult for the attacker to identify and pursue the right goal. The researchers therefore do not assume that there will be such attacks in the future.


In principle, security problems in connection with Bluetooth are nothing new. There have been attacks on Tesla cars, among other things. These gave the attackers access to the cars. Many other electronic devices have also been attacked. There are currently no real security mechanisms available with the technology. It could be that Bluetooth will be replaced by another technology in the near future. However, it is questionable whether there will not be security gaps there as well.

From offchain to offchain: Statechains meets Lightning

  Without a doubt, the most significant off-chain Bitcoin solution is the Lightning network. But in its wake, the statechain has emerged as an intriguing replacement. There is currently a proposal to link the two offchain networks. From an ocean, for example, you can see sunbeams glistening in the water, waves rippling, and possibly a jellyfish drifting toward the light. But you only see a small portion of it. The distance from the sea's surface to its bottom is hundreds of meters. It has dozens of different fish species swimming in it, crabs and starfish crawling on the bottom, shells clinging to rocks, and sea plants climbing up. A completely new world starts where your gaze diverges. You can picture a blockchain like Bitcoin, just like the sea. What you see on the outside is only a small portion of what is actually there; the set of UTXOs (coins) and transaction history that full nodes store are just the beginning of a much larger world. It's the plan, at least. With Bitcoin...

Phishing attack on popular crypto sites tries to empty wallets

  Several major crypto sites such as Etherscan, CoinGecko, DeFi Pulse, and others report malicious pop-ups scammers use to try to trick users into connecting their MetaMask wallets. The phishing attack came from a domain displaying the Bored Ape Yacht Club (BAYC) logo. "We are investigating the root cause of this attack to fix the threat as soon as possible," CoinGecko founder Bobby Ong tweeted. The phishing attack appears to have been triggered by a malicious ad script from Coinzilla, a crypto ad network, according to CoinGecko. Etherscan also advises its users not to confirm any transactions that may appear on the website. The attackers attempted to use the hype around the “bored monkeys” non-fungible tokens (NFT) to gain access to the cryptocurrencies of unsuspecting website visitors. Although the websites affected by the scam attempt have reacted in the last few hours and deactivated the advertising pop-up, it is still recommended not to connect your MetaMask wallet to ne...

Bored Ape Yacht Club NFTs stolen through phishing on Instagram

  Bored Ape Yacht Club ( BAYC ) developers announced on Monday that hackers have hijacked the official Instagram page of the popular NFT collection and posted links to a fake airdrop. Crypto enthusiasts who connected their MetaMask wallet to the rogue website subsequently had their Ape NFTs stolen. Apparently, the attack was planned to coincide with the one-year anniversary of the BAYC collection. This increased the "perceived credibility" of the phishing link. About 100 NFTs are said to have been stolen in the phishing attack . According to CoinGecko data , the minimum price for a BAYC NFT is 139 Ether ( ETH ) or $400,726. So if reports are correct, over $40 million worth of NFTs were stolen in the attack. These numbers are only the lowest estimate, however, as they are based on the lowest price.  At the time of writing, it was still unclear how the hackers gained access to BAYC's official Instagram account. Social media users have pointed out the importance of two-fact...
