### [1. The Sneakiest Ethereum “Scam” (honeypot) Ever](https://hackernoon.com/the-sneakiest-ethereum-scam-ever-6dc138061235)
![](https://hackernoon.com/hn-images/1*ogumd4kxN7_7aO182e1qmw.png)I’ve recently saw a tweet about a sneaky scam where someone would leak a privatekey of an account that owns some token and needs gas to withdraw them. It had a smart contract that would transfer any eth send to its address to another contract. I thought it was pretty good and it reminded of another “scam” I’ve seen few months ago that in my opinion is even sneakier. The common point is that both of these scams are trying to get money from people who had bad intentions in the first place.

![](https://hackernoon.com/hn-images/1*KtI9aizNagzWJr0Ld15ezA.jpeg)When the General Data Protection Regulation (GDPR) came into effect in May 2018 for entities operating in the European Union or targeting its citizens, most people assumed things would change immediately.

![](https://hackernoon.com/hn-images/1*JgmiuseGCW9VV497rd-zLQ.jpeg)Downgrade prevention has been a cat-and-mouse game between consumers and companies since the inception of remote updates. The <a href="https://hackernoon.com/tagged/nintendo" target="_blank">Nintendo</a> Switch adopts a worrisome-strategy of preventing <a href="https://hackernoon.com/tagged/firmware" target="_blank">firmware</a> downgrades by permanently modifying your device every time it updates. While this isn’t a new concept (the Xbox 360 was doing it back in 2007), it is part of a greater effort to prevent end users from modifying their devices to their liking.

### [8. Why You Should Never Save Passwords on Chrome or Firefox](https://hackernoon.com/why-you-should-never-save-passwords-on-chrome-or-firefox-96b770cfd0d0)
![](https://hackernoon.com/hn-images/1*VZxVMuHcQiTcxpDiQ5KeYQ.png)In this article I will demonstrate how easy it is for hackers to extract every username and password saved on your Chrome profile. One would think that Chrome would have safety measures to encrypt your password, but apparently that is not the case — sorta. My Chrome profile, like many others, is set up so that there is another encryption password that I have to enter in order to sync all my passwords, bookmarks, settings, browser history, and etc. so it was pretty shocking to me how easy it was for me to extract and decrypt my passwords. <em>Twelve lines of code&nbsp;easy.</em>

Now, it’s time to take your credit card out of your wallet and make the payment. As the site is secure and you have already done shopping on this e-commerce website in the past, you don’t think much before entering your credit/debit card details during the checkout.

### [10. Your Digital Photos Can Reveal Information About You](https://hackernoon.com/your-digital-photos-can-reveal-information-about-you-732783dd857b)
![](https://hackernoon.com/hn-images/1*9xuxCWB9pF1MjKM2rw2yJg.png)There is a saying that a “picture is worth a thousand words.” It was supposed to mean that an image can tell a story about the subject or about the picture. Our photos bring back memories that in itself tells us a lot about what we are viewing. In the age of digital photography that is so true because an image taken with a digital camera records information about the image as well. The problem is that the information is not only viewable to the user, but to everyone else as well. It may seem harmless at first, but so much information can be revealed by a photo once it is uploaded on the Internet to photo sharing websites, social media apps and blogs.

![](https://hackernoon.com/hn-images/1*UssPqElZPSU062FULsRU7w.png)Mining is a great way to enter the cryptocurrency ecosystem. However, Bitcoin/Litecoin is almost impossible to mine for the average user. It requires expensive equipment called ASICs that are made by a controversial, centralized company called Bitmain. These ASIC chips consume high amounts of electricity, and ASIC mining farms often use cheap &amp; ecologically-destructive coal power. These centralized mining cartels mint the vast majority of new Bitcoin, and are responsible for contentious forks of Bitcoin in order to maintain a monopoly of the network.

It’s easily the best thing out there for quickly doing cutting-edge fuzzing analysis on command line applications. But what about the situations where accessing the stuff you want to fuzz via command line isn’t so simple? Lots of times you can write a test harness (or maybe use <a href="https://llvm.org/docs/LibFuzzer.html" target="_blank">libFuzzer</a> instead), but what if you could just emulate the parts of the code that you want to fuzz and still get all the coverage-based advantages of AFL? For example, maybe you want to fuzz a parsing function from an embedded system that receives input via RF and isn’t easily debugged. Maybe the code you’re interested in is buried deep within a complex, slow <a href="https://hackernoon.com/tagged/program" target="_blank">program</a> that you can’t easily fuzz through any traditional <a href="https://hackernoon.com/tagged/tools" target="_blank">tools</a>.

![](https://hackernoon.com/hn-images/1*vxzduH9OGtCxyLGAPFpKIg.jpeg)Artificial intelligence, AI, has grabbed headlines, hype, and even consternation at the beast we are unleashing. Every powerful technology can be used for good and bad, be it nuclear or biotechnology, and the same is true for AI. While much of the public discourse from the likes of Elon Musk and Stephen Hawking reflects on sci-fi like dystopian visions of overlord AI’s gone wrong (a scenario certainly worth discussing), there is a much more immediate threat when it comes to AI. Long before AI goes uncontrollable or takes <a href="https://www.forbes.com/forbes/welcome/?toURL=https://www.forbes.com/sites/valleyvoices/2014/11/06/the-next-technology-revolution-will-drive-abundance-and-income-disparity/&amp;refURL=https://www.google.com/&amp;referrer=https://www.google.com/">over jobs</a>, there lurks a much larger danger: AI in the hands of governments and/or bad actors used to push self-interested agendas against the greater&nbsp;good.

![](https://hackernoon.com/hn-images/1*cjts5tSMbYD9IynMXIFyZA.png)The advances in wireless communications has led to an exponential growth in mobile devices i.e. smartphones. The deployment of 4G and LTE (Long Term Evolution) networks has delivered us more rich content, from video streaming to live gaming. It is taking its toll on bandwidth, which now needs to be addressed as demand grows. This time around a new class of applications that are bandwidth intensive like VR (Virtual Reality), AR (Augmented Reality) and OTT will require it. The telecom industry have specified a new standard called 5G to meet the growth of network demands. High speed data communications made possible by more bandwidth sounds like an excellent business proposition for wireless carriers to expand their networks, appease users and gain more subscribers while generating more revenues.

It has lots of limitations that make it clumsy and slow to employ against most real-world situations. For example, what if the binary you want to emulate calls an imported library function that is likely to call into the kernel such as <em>malloc() </em>or<em> printf()</em>? What if the code you want to fuzz is highly stateful, and requires lots of memory regions (heap allocations, stack pointers, global variables, etc.) that aren’t known until run-time? In fact, just about the only straightforward use of it that I’ve found is when working with flat embedded run-time system memory snapshots recovered from firmware by a debugger.

![](https://hackernoon.com/hn-images/1*jC0j9ZiWr3rt4sNlNBwtcA.jpeg)Websites that allow an individual to send a text message to any number are being used by fraudsters to send fake transaction messages impersonating a legitimate bank. The ability of these websites to modify the sender name of the SMS, i.e. to spoof any genuine entity, is what the fraudsters exploit for their benefits and typically form part of a larger scam chain. Numerous cases have been brought to the authorities regarding such SMS spoofing websites, which have called for legal proceedings against such service providers. These kinds of websites have continued to thrive exponentially. The victims of such scams are typically retailers who deal with high-end electronic equipment, jewelry, branded merchandise etc. A fraudster may initiate the scam by visiting a store and proceeding to select multiple items. The aim is to select items that amount to a large sum, thereby creating a situation wherein the fraudster pretends to have insufficient cash in hand to complete the purchase. The fraudster then requests for the bank details of the outlet so he can perform the bank transfer immediately. Once the bank details are in his possession, the fraudster accesses a SMS spoofing website, using it to send a message to the merchant’s mobile number which he had attained prior to the attack. This text message utilizes the victim’s bank name as the SMS sender, stating that his/her account has been accredited with a total sum owed for the items bought. The message would consist of the outlet’s account number (hashed till the last 4 digits), amount transferred and date of transaction. The structure of the message is intended to dupe the SMS recipient by prompting them to complete the purchase and handing over the merchandise. New elaborate schemes have been identified recently that show the SMS containing a landline number pretending to be the bank which is, in fact controlled by the fraudsters. A few moments after the SMS is received, a fake call is made to the SMS recipient pretending to verify the transaction and suggesting that the purpose of the call is to verify and check for any fraudulent activity. These messages may also have URL links which could be malicious. Further investigation has revealed that the recipient mobile number and bank details collected from the victim are used in other scams as well. A more prevalent scam involves a call placed from a fake landline, pretending to be from the bank asking to verify the victim’s information so that his/her records are up to date.

![](https://hackernoon.com/hn-images/1*_wemColnJ0oxGB4T5NX6Jw.jpeg)When you combine cryptography with malware, you get a very dangerous mix of problems. This is a type of computer virus that goes by another name, “ransomware”. This type of virus is part of a field of study called “cryptovirology”. Through the use of techniques called phishing, a threat actor sends the ransomware file to an unknowing victim. If the file is opened it will execute the virus payload, which is malicious code. The ransomware runs the code that encrypts user data on the infected computer or host. The data are user files like documents, spreadsheets, photos, multimedia files and even confidential records. The ransomware targets your personal computer files and applies an encryption algorithm like RSA which makes the file unaccessible. The only way to access them is if the user pays a ransom to the threat actor by following instructions which appear encoded into the encrypted files. Thus it is called ransomware, because a form of payment is demanded in order to fix the problem.
