ESET Security for IoT 0 964

IoT

IoT is a phrase used often in the cyber security space, but what does it really mean? IoT stands for Internet of Things and to put it simply, refers to any device that can be connected to the internet. This is no longer just computers or cellphones but also refers to Smart TV’s and fridges, coffee machines, headphones, speakers, wearable tech, cars and soon enough, pretty much anything.

A more formal definition of IoT given by TechTarget

The Internet of Things (IoT) is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.

With all of these connections, IoT provides endless opportunities but also poses dangers.

These dangers include:

  • Your devices being used to spy on you using capabilities such as cameras or voice recording software
  • Devices being hacked to obtain personal information or to take over functionality of the device
  • In addition to this, having multiple devices connected to the internet opens further opportunities for these devices to bypass firewalls and access other devices on your network.

To help protect your IoT devices, your home network, and even your favorite shopping or social website—ESET has enhanced the Connected Home Monitor feature within its recently released home products, available to try or upgrade to for free.

How the ESET connected home monitor addresses these dangers

The ESET connected home monitor includes IoT vulnerability detection, a router-connected smart devices test, and a catalog list of connected devices on your network.

The enhanced feature is continuously updated to detect and alert you to new devices connected to your network, as well as the latest vulnerabilities affecting your devices. If a vulnerability is found in a device, ESET will report the cause and possible steps you can make to fix it, such as changing default configurations or updating the device’s firmware from the manufacturer.

Time to change your Twitter password 0 592

Twitter Password

An internal bug exposed the passwords of an undisclosed number of the more than 330 million Twitter users.

Twitter CTO Parag Agrawal announced that it was a “bug that stored passwords unmasked in an internal log”. He went on to state “we have fixed the bug and our investigation shows no indication of breach or misuse”.

The Social Media platform are insisting that there is no sign of danger and that there is no reason to believe that the passwords were exposed outside of the organisation. However, they are still advising users to change their Twitter passwords and those of any other online service using the same password.

Some additional password tips from Twitter include enabling two-factor authentication and also using a password manager to create a strong and unique password for every individual online service.

Approximately US $150,000 worth of Ethereum-based cryptocurrency stolen 0 666

Online cryptocurrency website MyEtherWallet.com has confirmed that some visitors could have been temporarily redirected to a phishing site designed to steal users’ credentials and – ultimately – empty their cryptocurrency wallets.

According to reports, whoever was behind the attack may have successfully stolen approximately US $152,000 worth of Ethereum-based cryptocurrency.

However,  MyEtherWallet may not have been at fault, as the website explained in its statement:

“This is not due to a lack of security on the [MyEtherWallet] platform. It is due to hackers finding vulnerabilities in public facing DNS servers.”

British security researcher Kevin Beaumont confirms in a blog post that some of MyEtherWallet’s traffic had been redirected to a server based in Russia after traffic intended for Amazon’s DNS resolvers was pointed to a server hosted in Chicago by Equinix.

For the scheme to succeed, someone pulled off a hijack of a crucial component of the internet known as Border Gateway Protocol (BGP), to reroute traffic intended for Amazon’s Route 53 DNS service to the server in Chicago. As a consequence, for some users, entering myetherwallet.com into their browser did not take them to the genuine site but instead to a server at an IP address chosen by the hackers.

The only obvious clue that a typical user might have spotted was that when they visited the fake MyEtherWallet site they would have seen an error message telling them that the site was using an untrustworthy SSL certificate.

It seems that the attackers made a mistake in not obtaining a valid SSL certificate.

Despite the error with their SSL certificate, the hackers haven’t done badly for themselves – both in this attack and in the past. Fascinatingly, the bogus MyEtherWallet website set up by the criminals was moving stolen cryptocurrency into a wallet which already contained some US $27 million worth of assets. Inevitably that raises questions of its own – have the hackers already made a substantial fortune through other attacks, or might their activities be supported by a nation state?

In a statement Equinix confirmed that a customer’s equipment at its Chicago data center was used in the hackers’ hijacking of Amazon’s Route 53 DNS service:

“The server used in this incident was not an Equinix server but rather customer equipment deployed at one of our Chicago IBX data centers… We generally do not have visibility or control over what our customers – or customers of our customers – do with their equipment.”

Amazon however, do not find the blame to lie on themselves, communicating the following statement:

“Neither AWS nor Amazon Route 53 were hacked or compromised. An upstream Internet Service Provider (ISP) was compromised by a malicious actor who then used that provider to announce a subset of Route 53 IP addresses to other networks with whom this ISP was peered. These peered networks, unaware of this issue, accepted these announcements and incorrectly directed a small percentage of traffic for a single customer’s domain to the malicious copy of that domain.”

Some advice from award winning security blogger, researcher and speaker, Graham Cluley – avoid putting your cryptocurrency wallet online, keep them off your smartphone or computer and perhaps instead invest in a hardware wallet.
