TheMerkle Solar Panels Cyber Attack

Most people would not consider cyber attacks on solar panels to be capable of causing much damage. Researchers, however, have shown that such threats should not be taken lightly. There are multiple vulnerabilities found in products manufactured by the leading providers of photovoltaics. A serious cyber attack against solar panels could shut down an entire nation’s power grid.

Hacking Solar Panels Could Be a Thing

Given the current popularity of solar panels, it is only normal that security researchers would take a closer look at their built-in security. As it turns out, top manufacturers have left significant security vulnerability in their products, all of which could be exploited by cybercriminals with relative ease. If these vulnerabilities were to be exploited on a large scale, they might very well shut down power grids in entire nations. 

New research on these security vulnerabilities was published late last week. The worst-case scenario is known as the “Horus Scenario” and relates to 21 different vulnerabilities that have been discovered. Two-thirds of these flaws rely on receiving CVE (Common Vulnerabilities and Exposures) identifiers. The researcher disclosed these flaws to the manufacturers in question back in December of 2016, and he even gave them proof of concept attack vectors in January of 2017. This shows that those flaws required being patched sooner rather than later.

If a malicious actor were to exploit any of the flaws pointed out by this research, he or she would succeed in damaging the normal functioning of a solar power plant. Power grids are built in such a way that any disturbance will have a long-lasting effect. If one panel is attacked, the issue will quickly spread to other photovoltaic panels as well. Considering how power grids are often interconnected in many countries, this could have major repercussions due to a cascading domino effect. If country A’s grid goes out, they will necessarily draw power from country B, which then requires more power from country C, and so on.

Interconnected power grids are based on the principle of estimated power supply and consumption. A solar eclipse, for example, allows power grid regulators to increase the production of electricity using other means in order to cover the lack of energy generated by solar plants. An unplanned malicious attack, however, gives no room to prepare backup solutions. It would effectively cripple some countries’ power grids altogether, although it remains to be seen just how long that effect would last.

According to the security researcher involved with this project, a hacker could easily shut down production of solar plants and cause the equivalent of a solar eclipse. It is not hard to see why this would have incredibly dire consequences. While it would cause a monetary loss for the solar plant’s owners, this would only be a secondary concern in the grand scheme of things. After all, the power grid itself would undergo a massive shock.

One country which would be severely affected by such a hack is Germany, since between 30 and 50 percent of its power demand is covered by photovoltaic panels. A cyber attack on that grid in particular at the right time would take out nearly half of the country’s entire power supply, which would be catastrophic. It could also cause continent-wide power outages due to the way its power grid is interlinked with the rest of Europe. Solar energy cannot be stored indefinitely, and producing new power takes up a lot of valuable time.

Changelly Users Grow Restless as Number of Missing Transactions Increases

TheMerkle Changelly Missing Funds

It seems things have gone from bad to worse for Changelly. As most people know, Changelly is a competitor to ShapeShift. The company facilitates instant exchanges between various cryptocurrencies without the need for an account. It is one of the projects built by the MinerGate team. However, the platform has recently been facing a lot of complaints seemingly not addressed by its customer support team.

What is up With Changelly?

Looking over the Changelly subreddit, there are a lot of complaints to be found. Whether all of them are justified is a different matter, but it does not look good regardless. There appears to be a growing number of reports related to transactions that have either not completed, failed, or gone missing. That is never a good sign for instant exchange services, considering that all of these transactions pertain to receiving funds, rather than sending them to the company.

These issues are not linked to any one cryptocurrency either, which only makes things even more complicated. It seems any form of deposit shows up just fine, but exchanging to another currency of your choice is a massive problem right now. Failed transactions and not issuing refunds for “stuck” transfers is wholly unacceptable. All of this has caused delays for users who rely on instant exchange services. If one’s transfer takes 24 hours or more to complete due to an error, it defeats the purpose of instant exchanges entirely.

A lot of these issues go back one or more days, indicating that Changelly has done little to address the problem. It is expected that users would start complaining on Reddit, as that is often the fastest way to get a response. The same happens with most cryptocurrency exchanges experiencing long support ticket queues. In a lot of cases, pinging the company on Reddit magically spawns a representative who will deliver help within the hour. By contrast, Changelly has yet to issue official responses to anyone on Reddit.

One user stated that he had received an email from the Changelly support team alluding to “technical issues” and indicating that most of these problems would be resolved in the next two to three days. Though that will put some people’s minds at ease, it still does not explain why the company has been struggling suddenly. Rest assured that there will be plenty of speculation regarding this development. In all likelihood, it will only be a matter of time before rumors regarding hacks or insolvency surface. Until the company issues a statement, such rumors should be ignored.

Unfortunately, it is difficult to gauge how much money is currently missing or stuck. However, there are a lot of very annoyed Changelly users right now and understandably so. Until the company solves all of these problems, things will continue to be challenging for them. PR nightmares like these can haunt companies for weeks, if not months or years. We sincerely hope that all affected users see their money again one way or another, but it remains to be seen if that will be the case anytime soon.

Interestingly enough, the company has remained active on social media, but has not issued any statement regarding the ongoing issues. It did post a tutorial on how to exchange Bitcoin for Bitcoin Cash, which means the platform will support BCH from now on. However, supporting the new currency will do them little good if dozens of users are complaining about missing funds. It will be interesting to see how and if the company responds to this list of problems. If all goes according to plan, everything should be back in order by Friday at the latest. Whether or not that will be the case remains to be seen.

Upcoming Bitcoin Core Client Will Disconnect SegWit2x Nodes Automatically

Now that SegWit activation has been locked in and BIP148 is in effect, the new client will disconnect nodes supporting the SegWit2x fork.

TheMerkle Bitcoin Core Blocking SegWit2x

The upcoming Bitcoin Core client update will introduce some interesting changes. Now that SegWit activation has been locked in and BIP148 is in effect, the new client will disconnect nodes supporting the SegWit2x fork. This decision will not go over well with a lot of SegWit2x supporters, as they will see this as an unwarrented attack against the project.

Bitcoin Core 0.15.0 Disconnects SegWit2x Clients

Any radical change made to the Bitcoin Core client is always greeted with a lot of skepticism. This new change introduced in Bitcoin Core 0.15.0 will not be any different, as it seems to be a rather radical decision. Automatically disconnecting any network node which runs the SegWit2x fork seems rather unusual. However, such a decision was to be expected sooner or later. Bitcoin Core supporters have no intention to see a support a solution which introduces 2MB blocks anytime soon.

The community seems to be divided over this decision for the time being. Some people feel it makes perfect sense to do so, as nodes running on different forks will not provide any use to one another. The SegWit2x client is more than capable of dealing with the changes recently introduced to the Bitcoin blockchain, such as rejecting non-SegWit blocks. It seems as if the Bitcoin Core developers want to prevent the November hard fork from introducing any major disruption to the average Bitcoin user, which can be justified.

This updated client will be released well ahead of the November fork. Disconnecting SegWit2x nodes from the network altogether will create a rather interesting scenario. Not everyone will agree with this radical decision at this time, even though it seems the Core developers have a good reason for making this change. Nullc points out not all SegWit2x nodes are 100% compatible with the current network conditions either. That statement makes a lot of sense, although not everyone seems to be on the same page regarding this topic.

The vast majority of Bitcoin Core supporters feel this is the best decision the developers have made in quite some time. It is heralded as “excellent news,” as the Core community wants nothing to do with SegWit2x. This will certainly have some repercussions in the long run, although the real impact has yet to be determined. SegWit2x would be a hard fork anyway and removing the nodes from the network now could turn out to be the smart thing to do after all.

Even though the majority of Bitcoin users have come together to lock in SegWit activation, there are still a lot of different opinions regarding the future. Core developers feel SegWit alone is more than sufficient to make Bitcoin scale and pave the way for the Lightning Network. SegWit2x die-hards want that 2MB block increase in November, alongside the activation of Segregated Witness. These discussions have been going on for quite some time now, yet it seems there will not be unity among Bitcoin supporters anytime soon.

For the time being, it is unclear when we can expect the Bitcoin Core 0.15.0 client. It still needs to go through several release candidates before people can even consider downloading it. Considering it does not introduce any forks -neither soft nor hard- the testing and review period for this new client should not last all that long. It is good to see some changes being introduced without discussions regarding forking Bitcoin and potential chain splits. Many people feel SegWit2x is not the right way to go, but only time will tell.

Like the humans it serves, wearable technology comes in many different shapes and sizes. While most people utilize this technology for comfort or self-tracking, other manufacturers are interested in collecting sensitive body vitals. A new device of this type has been created which stimulates sweat glands on a small patch of one’s skin. This has the looks of an intriguing solution that could provide valuable insights into one’s personal health.

New Medical Sensor Collects Your Sweat

Scientists have recently used medical sensors to collect and sample sweat. Collecting this fluid allows them to analyze a patient’s body far more thoroughly than most other methods ever could. Analyzing sweat can often yield results similar to those obtained by collecting blood, but without the invasive procedure.

The one problem in all of this was making people sweat. Other than cardio exercises or going for a few sprints, there was no reliable way to stimulate sweat glands properly. That has now changed, thanks to a new prototype product developed by researchers. A new sensor the size of a regular Band-Aid can stimulate sweat glands on a small patch of one’s skin. This means it can collect sweat from a small part of the body without requiring that the wearer exert himself physically. It is an ideal solution for us lazy people who still wish to check up on our health.

This small sensor uses a microcurrent (0.2mA) to send the chemical carbachol into the upper layer of the user’s skin. That is all there is needed before sweat is produced and the sensor can start measuring the electrolytes in the sweat. It is a very practical solution for gathering important data from one’s body without the need for blood work. Monitoring blood continuously is both impractical and impossible, whereas one can easily stimulate sweat glands multiple times throughout the day without side effects.

Sweat also has a much later “expiration date” when it comes to monitoring vitals. The scientists have determined that averages with a sample can provide them with valuable information for up to five hours once it has been collected. That is quite a significant development. For any type of health monitoring situation that requires continuous monitoring, collecting sweat would now seem to be the preferable option.

As it turns out, this sensor may become commercially viable a lot sooner than most people anticipate. Eccrine Systems is the company responsible for refining and commercializing the sweat-inducing sensor, and it is working on it feverishly. The company was co-founded by one of the researchers responsible for generating this solution in the first place. This is a very interesting concept that may change the way we think about healthcare altogether.

For the time being, it remains to be seen when these sensors will become commonplace. This is definitely a solution that will make the healthcare sector a lot more efficient. Sweat samples will not be replacing blood work anytime soon, but they can be useful in their own right. It will be interesting to see how this new sweat-inducing sensor affects the way we conduct regular health checkups. It is not unlikely that the sensor would be embedded within consumer electronics à la Fitbit in the future.
