Here’s Some Bitcoin: Oh, and You’ve Been Served!

By BrianKrebs

A California man who lost $100,000 in a 2021 SIM-swapping attack is suing the unknown holder of a cryptocurrency wallet that harbors his stolen funds. The case is thought to be the first in which a federal court has recognized the use of information included in a bitcoin transaction — such as a link to a civil claim filed in federal court — as reasonably likely to provide notice of the lawsuit to the defendant. Experts say the development could make it easier for victims of crypto heists to recover stolen funds through the courts without having to wait years for law enforcement to take notice or help.

Ryan Dellone, a healthcare worker in Fresno, Calif., asserts that thieves stole his bitcoin on Dec. 14, 2021, by executing an unauthorized SIM-swap that involved an employee at his mobile phone provider who switched Dellone’s phone number over to a new device the attackers controlled.

Dellone says the crooks then used his phone number to break into his account at Coinbase and siphon roughly $100,000 worth of cryptocurrencies. Coinbase is also named as a defendant in the lawsuit, which alleges the company ignored multiple red flags, and that it should have detected and stopped the theft. Coinbase did not respond to requests for comment.

Working with experts who track the flow of funds stolen in cryptocurrency heists, Dellone’s lawyer Ethan Mora identified a bitcoin wallet that was the ultimate destination of his client’s stolen crypto. Mora says his client has since been made aware that the bitcoin address in question is embroiled in an ongoing federal investigation into a cryptocurrency theft ring.

Mora said it’s unclear if the bitcoin address that holds his client’s stolen money is being held by the government or by the anonymous hackers. Nevertheless, he is pursuing a novel legal strategy that allows his client to serve notice of the civil suit to that bitcoin address — and potentially win a default judgment to seize his client’s funds within — without knowing the identity of his attackers or anything about the account holder.

In a civil lawsuit seeking monetary damages, a default judgment is usually entered on behalf of the plaintiff if the defendant fails to respond to the complaint within a specified time. Assuming that the cybercriminals who stole the money don’t dispute Dellone’s claim, experts say the money could be seized by cryptocurrency exchanges if the thieves ever tried to move it or spend it.

The U.S. courts have generally held that if you’re going to sue someone, you have to provide some kind of meaningful and timely communication about that lawsuit to the defendant in a way that is reasonably likely to provide them notice.

Not so long ago, you had track down your defendant and hire someone to physically serve them with a copy of the court papers. But legal experts say the courts have evolved their thinking in recent years about what constitutes meaningful service, and now allow notification via email.

On Dec. 14, 2023, a federal judge in the Eastern District of California granted Dellone permission to serve notice of his lawsuit directly to the suspected hackers’ bitcoin address — using a short message that was attached to roughly $100 worth of bitcoin Mora sent to the address.

Bitcoin transactions are public record, and each transaction can be sent along with an optional short message. The message uses what’s known as an “OP RETURN,” or an instruction of the Bitcoin scripting language that allows users to attach metadata to a transaction — and thus save it on the blockchain.

In the $100 bitcoin transaction Mora sent to the disputed bitcoin address, the OP RETURN message read: “OSERVICE – SUMMONS, COMPLAINT U.S. Dist. E.D. Cal. LINK: t.ly/123cv01408_service,” which is a short link to a copy of the lawsuit hosted on Google Drive.

“The courts are adapting to the new style of service of process,” said Mark Rasch, a former federal prosecutor at the U.S. Department of Justice. “And that’s helpful and useful and necessary.”

Rasch said Mora’s strategy could force the government to divulge information about their case, or else explain to a judge why the plaintiff shouldn’t be able to recover their stolen funds without further delay. Rasch said it could be that Dellone’s stolen crypto was seized as part of a government asset forfeiture, but that either way there is no reason Uncle Sam should hold some cybercrime victims’ life savings indefinitely.

“The government doesn’t need the crypto as evidence, but in a forfeiture action the money goes to the government,” Rasch said. “But it was never the government’s money, and that doesn’t help the victim. The government should be providing information to the victims of cryptocurrency theft so that their attorneys can go get the money back themselves.”

Nick Bax is a security researcher who specializes in tracing the labyrinthine activity of criminals trying to use cryptocurrency exchanges and other financial instruments to launder the proceeds of cybercrime. Bax said Mora’s method could allow more victims to stake legitimate legal claims to their stolen funds.

“If you get a default judgment against a bitcoin address, for example, and then down the road that bitcoin gets sent to an exchange that complies with or abides by U.S. court orders, then it’s yours,” Bax said. “I’ve seen funds with a court order on them get frozen by the exchanges that decided it made sense to comply with orders from a U.S. federal court.”

Bax’s research was featured in a Sept. 2023 story here about how experts now believe it’s likely hackers are cracking open some of the password vaults stolen in the 2022 data breach at LastPass.

“I’ve talked to a lot victims who have had life-changing amounts of money being seized and would like that money back,” Bax said. “A big goal here is just making civil cases more efficient. Because then people can help themselves and they don’t need to rely solely on law enforcement with its limited resources. And that’s really the goal: To scale this and make it economically viable.”

While Dellone’s lawsuit may be the first time anyone has obtained approval from a federal judge to use bitcoin to notify another party of a civil action, the technique has been used in several recent unrelated cases involving other cryptocurrencies, including Ethereum and NFTs.

The law firm DLAPiper writes that in November 2022, the U.S. District Court for the Southern District of Florida “authorized service of a lawsuit seeking the recovery of stolen digital assets by way of a non-fungible token or NFT containing the text of the complaint and summons, as well as a hyperlink to a website created by the plaintiffs containing all pleadings and orders in the action.”

In approving Dellone’s request for service via bitcoin transaction, the judge overseeing the case cited a recent New York Superior Court ruling in a John Doe case brought by victims seeking to unmask the crooks behind a $1.3 million cyberheist.

In the New York case, the state trial court found it was acceptable for the plaintiffs to serve notice of the suit via cryptocurrency transactions because the defendants regularly used the Blockchain address to which the tokens were sent, and had recently done so. Also, the New York court found that because the account in question contained a significant sum of money, it was unlikely to be abandoned or forgotten.

“Thus the court inferred the defendants were likely to access the account in the future,” wrote Judge Helena M. March-Kuchta, for the Eastern District of California, summarizing the New York case. “Finally, the plaintiff had no alternative means of contacting these unknown defendants.”

Experts say regardless of the reason for a cryptocurrency theft or loss — whether it’s from a romance scam or a straight-up digital mugging — it’s important for victims to file an official report both with their local police and with the FBI’s Internet Crime Complaint Center (ic3.gov). The IC3 collects reports on cybercrime and sometimes bundles victim reports into cases for DOJ/FBI prosecutors and investigators.

The hard truth is that most victims will never see their stolen funds again. But sometimes federal investigators win minor victories and manage to seize or freeze crypto assets that are known to be associated with specific crimes and criminals. In those cases, the government will eventually make an effort to find, contact and in some cases remunerate known victims.

It might take many years for this process to unfold. But if and when they do make that effort, federal investigators are likely to focus their energies and attention responding to victims who staked a claim and can support it with documentation.

But have no illusions that any of this is likely to happen in a timeframe that is meaningful to victims in the short run. For example, in 2013 the U.S. government seized the assets of the virtual currency Liberty Reserve, massively disrupting a major vehicle for laundering the proceeds of cybercrime and other illegal activities.

When the government offered remuneration to Liberty Reserve account holders who wished to make a financial loss claim and supply supporting documentation, KrebsOnSecurity filed a claim. There wasn’t money much in my Liberty Reserve account; I simply wanted to know how long it would take for federal investigators to follow up on my claim, or indeed if they would at all.

In 2020 KrebsOnSecurity was contacted by an investigator with the U.S. Internal Revenue Service (IRS) who was seeking to discuss my claim. The investigator said they would have called sooner, but that it had taken that long for the IRS to gain legal access to the funds seized in the 2013 Liberty Reserve takedown.

Discord Admins Hacked by Malicious Bookmarks

By BrianKrebs

A number of Discord communities focused on cryptocurrency have been hacked this past month after their administrators were tricked into running malicious Javascript code disguised as a Web browser bookmark.

This attack involves malicious Javascript that is added to one’s browser by dragging a component from a web page to one’s browser bookmarks.

According to interviews with victims, several of the attacks began with an interview request from someone posing as a reporter for a crypto-focused news outlet online. Those who take the bait are sent a link to a Discord server that appears to be the official Discord of the crypto news site, where they are asked to complete a verification step to validate their identity.

As shown in this Youtube video, the verification process involves dragging a button from the phony crypto news Discord server to the bookmarks bar in one’s Web browser. From there, the visitor is instructed to go back to discord.com and then click the new bookmark to complete the verification process.

However, the bookmark is actually a clever snippet of Javascript that quietly grabs the user’s Discord token and sends it to the scammer’s website. The attacker then loads the stolen token into their own browser session and (usually late at night after the admins are asleep) posts an announcement in the targeted Discord about an exclusive “airdrop,” “NFT mint event” or some other potential money making opportunity for the Discord members.

The unsuspecting Discord members click the link provided by the compromised administrator account, and are asked to connect their crypto wallet to the scammer’s site, where it asks for unlimited spend approvals on their tokens, and subsequently drains the balance of any valuable accounts.

Meanwhile, anyone in the compromised Discord channel who notices the scam and replies is banned, and their messages are deleted by the compromised admin account.

Nicholas Scavuzzo is an associate at Ocean Protocol, which describes itself as an “open-source protocol that aims to allow businesses and individuals to exchange and monetize data and data-based services.” On May 22, an administrator for Ocean Protocol’s Discord server clicked a link in a direct message from a community member that prompted them to prove their identity by dragging a link to their bookmarks.

Scavuzzo, who is based in Maine, said the attackers waited until around midnight in his timezone time before using the administrator’s account to send out an unauthorized message about a new Ocean airdrop.

Scavuzzo said the administrator’s account was hijacked even though she had multi-factor authentication turned on.

“A CAPTCHA bot that allows Discord cookies to be accessed by the person hosting the CAPTCHA,” was how Scavuzzo described the attack. “I’ve seen all kinds of crypto scams, but I’ve never seen one like this.”

In this conversation, “Ana | Ocean” is a compromised Discord server administrator account promoting a phony airdrop.

Importantly, the stolen token only works for the attackers as long as its rightful owner doesn’t log out and back in, or else change their credentials.

Assuming the administrator can log in, that is. In Ocean’s case, one of the first things the intruders did once they swiped the administrator’s token was change the server’s access controls and remove all core Ocean team members from the server.

Fortunately for Ocean, Scavuzzo was able to reach the operator of the server that hosts the Discord channel, and have the channel’s settings reverted back to normal.

“Thankfully, we are a globally distributed team, so we have people awake at all hours,” Scavuzzo said, noting that Ocean is not aware of any Discord community members who fell for the phony airdrop offer, which was live for about 30 minutes. “This could have been a lot worse.”

On May 26, Aura Network reported on Twitter that its Discord server was compromised in a phishing attack that resulted in the deletion of Discord channels and the dissemination of fake Aura Network Airdrop Campaign links.

On May 27, Nahmii — a cryptocurrency technology based on the Ethereum blockchain — warned on Twitter that one of its community moderators on Discord was compromised and posting fake airdrop details.

On May 9, MetrixCoin reported that its Discord server was hacked, with fake airdrop details pushed to all users.

KrebsOnSecurity recently heard from a trusted source in the cybersecurity industry who dealt firsthand with one of these attacks and asked to remain anonymous.

“I do pro bono Discord security work for a few Discords, and I was approached by one of these fake journalists,” the source said. “I played along and got the link to their Discord, where they were pretending to be journalists from the Cryptonews website using several accounts.”

The source took note of all the Discord IDs of the admins of the fake Cryptonews Discord, so that he could ensure they were blocked from the Discords he helps to secure.

“Since I’ve been doing this for a while now, I’ve built up a substantial database of Discord users and messages, so often I can see these scammers’ history on Discord,” the source said.

In this case, he noticed a user with the “CEO” role in the fake Cryptonews Discord had been seen previously under another username — “Levatax.” Searching on that Discord ID and username revealed a young Turkish coder named Berk Yilmaz whose Github page linked to the very same Discord ID as the scammer CEO.

Reached via instant message on Telegram, Levatax said he’s had no involvement in such schemes, and that he hasn’t been on Discord since his Microsoft Outlook account was hacked months ago.

“The interesting thing [is] that I didn’t use Discord since few months or even social media because of the political status of Turkey,” Levatax explained, referring to the recent election in his country. “The only thing I confirm is losing my Outlook account which connected to my Discord, and I’m already in touch with Microsoft to recover it.”

The verification method used in the above scam involves a type of bookmark called a “bookmarklet” that stores Javascript code as a clickable link in the bookmarks bar at the top of one’s browser.

While bookmarklets can be useful and harmless, malicious Javascript that is executed in the browser by the user is especially dangerous. So please avoid adding (or dragging) any bookmarks or bookmarklets to your browser unless it was your idea in the first place.

Honoring our ‘Cybersecurity Defender of the Year’ in EMEA

By Neville Letzerich

Congratulations to security advocate Luigi Vassallo, Chief Operating Officer and Chief Technology Officer of Sara Assicurazioni Insurance, an innovative Italian cloud-first insurance firm.

In the last two years, cybersecurity has advanced and can feel like a one-two punch to those who are not prepared. But what does that preparation look like? For Luigi Vassallo, it was more than just tackling cybersecurity defense on his own. Luigi reached out to the Cisco community, offering his knowledge and expertise to help others. This is what stood out to make him our Cybersecurity Defender of the Year in EMEA for the Cisco Global Advocate Awards 2023 EMEA event.

Cisco’s advocacy community, Cisco Insider Advocates, brings our customers together and provides a way for them to make powerful connections, expand their professional and personal networks, and learn from top experts in their field. Luigi personifies the spirit of Insider Advocates by sharing freely within the community.

One may wonder where Luigi finds the time or energy to participate in the community. Luigi finds immeasurable energy by training as a kickboxer and as an avid cyclist. This energy transforms into a philosophy of helping others. As Luigi says, it is about being “the best version of yourself.”

Luigi sums up his approach to cybersecurity this way: “Cybersecurity for me is like boxing: you never know when your opponent will attack, but you have to know in advance how to respond and what you can do.”

Luigi has been featured in a profile piece, as well as a video, where he speaks about his personal goals, as well as his goals for making Sara Assicurazioni as secure as possible with Cisco’s products. Part of his passion comes from being comfortable with the uncertainty of cybersecurity, coupled with the confidence that Cisco is there to help his organization. I’m honored that Sara Assicurazioni has joined forces with Cisco Secure to confidently define zero-trust and XDR strategies that increase security resilience and drive better customer outcomes for them.

When notified of the award, Luigi’s humility and dedication to the community was evident, as he shared, “I feel happy and surprised about this award, as I didn’t expect to win because there were so many good advocates who were nominated with me. I want to thank Cisco for awarding me the Cybersecurity Defender of the Year honor.”

Luigi also credits the Cisco Insider Advocacy program for its ability to connect and grow the cybersecurity community, adding:

“This is also what makes Cisco different from other security vendors; the capacity to recognize the innovation and resilience of its customers. I feel that we are part of the same movement, and we are together in the same fight against cybercriminals. To all other nominees, I want to say thank you for your hard work in cybersecurity and in sharing your good practices with me in the Cisco Insider Advocacy community and now at Cisco Live EMEA.”

We congratulate Luigi, not only for keeping his guard up, but for helping others to do the same by being part of the Cisco Insider Advocacy community.

The Cisco Global Advocate Awards celebrates Cisco’s passionate and innovative customer advocates who go above and beyond in demonstrating thought leadership and supporting Cisco through success stories, speaking engagements, product reviews, and so much more.

We’re planning three exclusive events that will coincide with Cisco Live conferences in Amsterdam, Las Vegas, and Melbourne in 2023. We hope you’ll join us as we recognize our customer advocates by region for actively supporting Cisco. You won’t want to miss it.

Do the Benefits of Bitcoin Outweigh the Risks?

By Vishnu Varadaraj

What do Burger King and the popular “Doge” meme have in common? They both have cryptocurrencies named after their likeliness. WhopperCoin and Dogecoin are just two examples of the thousands of types of cryptocurrencies that have caught users’ attention over the past few years. Cryptocurrencies are digital tokens generated by a computer after solving complex mathematical functions. These functions are used to verify the authenticity of a ledger, or blockchain.  

Bitcoin is the most popular cryptocurrency today, increasing its value by almost 300% in 2020. Today, almost 46 million Americans own at least one share of Bitcoin, illustrating how these cryptocurrencies are the future of tomorrow’s digital payment system — or are they? The same benefits that make them a popular choice with online users have also made them popular amongst online thieves, sparking a wave of ransomware attacks and other cyberattacks more recently. This begs the question: do the benefits of Bitcoin outweigh the risks? 

Bitcoin: Benefits vs. Risks 

Every rose has its thorn, and several Bitcoin benefits seem to be hitched to online security risks. Here are some cryptocurrency characteristics that may seem appealing to users, but also provide cybercriminals with an opportunity to exploit:  

Purchase discretion and user autonomy 

As previously mentioned, cryptocurrency exchanges take place on an online public ledger, or blockchain, to secure online transactions. This means that anybody can observe the exchange online. However, the parties making the transactions are anonymous, disguised with a random number. Bitcoin users can make purchases that are never associated with their identity, similar to a cash transaction.  

While the purchase discretion provided by Bitcoin may be appealing to users who want to remain private, this characteristic could also aid cybercriminals in malicious activity. Due to the anonymity of Bitcoin transactions, there is no way for someone to associate a person with a certain cryptocurrency wallet. Furthermore, a user could have multiple wallets, allowing them to spread their currency from one address to another.  

For a cybercriminal looking to target an individual with ransomware, the purchase discretion and anonymity of Bitcoin provide a favorable solution. In fact, Bitcoin accounts for approximately 98% of ransomware payments today. Say a hacker carries out a ransomware attack and demands that the user pay a large sum in Bitcoin. If the user completes the payment, the hacker can keep moving the currency from one anonymous account to another. That makes it very difficult — though not impossible — to trace if the individual decides to investigate the case and tries to get their money back. 

No more middleman  

Another characteristic that Bitcoin users find appealing is the autonomy offered by digital currencies. In theory, they allow users more autonomy over their own money than government-regulated currencies do. With Bitcoin, users can control how they spend their money without dealing with an intermediary authority like a bank or government. 

This lack of intermediary authority also opens a door for hackers to exploit. Say a user decides that they want to manage their finances using Bitcoin to bypass banking fees and send money to friends and family in different parts of the world. As previously mentioned, a Bitcoin user is assigned an anonymous private key that acts as their security credential. This key is generated and maintained by the user instead of a third-party agency. But what happens if the key isn’t random enough? An attacker could steal the user’s private key, and they will not be able to recover it since the Bitcoin blockchain is not dependent on any centralized third-party institutions. Therefore, it will be very difficult to track the attacker’s behaviors and recover lost funds.  

How Consumers Can Protect Themselves from Cryptocurrency-Driven Attacks 

It is safe to say that Bitcoin has caused a lot of buzz. But do the benefits outweigh the risks? Due to the nature of Bitcoin and most other public blockchains, anyone in the world can perform transactions or cryptographic computations — including cybercriminals. That’s why it is crucial for current cryptocurrency users and those considering cryptocurrency investment to do their research and know what vulnerabilities lie within the world of Bitcoin.  

Follow these tips to help protect yourself from common threats that leverage cryptocurrency:  

 1. Do your homework.  

With blockchain, cryptocurrency, and any new and emerging technology, make sure you always remain a bit skeptical. Do your homework before you embrace the technology — research your options and make note of any known security issues and what you can do to mitigate known risks. 

 2. Don’t pay the ransom.  

If a hacker does target you with ransomware demanding Bitcoin payment, it’s best not to pay the ransom. Although you may feel in the moment that this is the only way to get your encrypted files back, there is no guarantee that the ransomware developers will send a decryption tool once they receive the payment. Paying the ransom also contributes to the development of more ransomware families, so it is best to hold off on making any payments. Furthermore, a recent study found that 80% of businesses that choose to pay a ransom experience a subsequent ransomware attack. While it may feel like your only option in the moment, paying a ransom could show attackers that you’re willing to make the payment, therefore positioning you as an ideal target for yet another attack.   

3. Back up your data.  

If you are targeted with ransomware, it’s crucial that you always have backup copies of your files, preferably in the cloud and on an external hard drive. This way, if you do get a ransomware infection, you can wipe your computer or device and reinstall your files from the backup. Backups protect your data, and you won’t be tempted to reward the hackers by paying a ransom. Backups won’t prevent ransomware, but they can mitigate the risks.  

4. Update your credentials.  

Large organizations often fall prey to ransomware attacks, so take necessary precautions if a company you’ve interacted with becomes compromised from a data leak or a ransomware attack. Immediately change your passwords for all your accounts, ensuring they are strong and unique. You can also employ a password manager to keep track of your credentials and generate secure login keys.  

5. Use a comprehensive security solution 

Add an extra layer of security with a solution such as McAfee® Total Protection, which includes Ransom Guard, to help protect your devices from these cyberthreats and ensure your digital wellness online.  

The emergence of Bitcoin has indeed facilitated a wave of cybercrime that was previously difficult to perceive. In this new age of digital payments, blockchain, and cryptocurrencies, make sure that you do your research and stay vigilant when it comes to protecting your online safety. Remember: Bitcoin worth will continue to fluctuate, but your personal security will always remain invaluable.

Digital Divorce: Who Gets the Airline Miles and Music Files?

By Judith Bitterli
digital assets

Something you’ll want to know about all those movies, mp3s, eBooks, air miles, and hotel points you’ve accrued over the yearsthey’re digital assets that can factor into a divorce settlement. 

Understandably, several factors determine the distribution of assets in a divorce. However, when it comes to dividing digital assets, divorce settlements and proceedings are charting new territoryThe rate of digital innovation and adoption in recent years has filled our phones, tablets, and computers with all manner of digital assets. What’s more, there are also the funds sitting in our payment apps or possibly further monies kept in the form of cryptocurrencies like bitcoinPut plainly, the law is catching up with regards to the distribution of these and other digital assets like them. 

Yet one thing that the law recognizes is that digital assets can have value and thus can be considered property subject to distribution in a divorce. 

In light of this, the following is a checklist of considerations that can help prepare you or someone you know for the distribution of digital assets in a fair and just way.  

Nothing offered in this article is legal advice, nor should it be construed as such. For legal advice, you can and should turn to your legal professional for counsel on the best approach for you and the laws in your area.  

What is a digital asset? 

For starters, let’s get an understanding as to what actually constitutes a digital asset. 

Because laws regarding digital assets vary (and continue to evolve), the best answer you can get to this question will come from your legal counsel. However, for purposes of discussion, a digital asset is any text or media in digital form that has value and offers the bearer the right to use it.  

To put that in practical termslet’s look at some real-world examples of what could constitute a digital asset. That list includes, but is not limited to: 

  • Photo libraries 
  • eBook libraries 
  • Digital movies 
  • Digital music 
  • Digital currency, such as bitcoin 
  • Air miles 
  • Hotel points 

However, digital assets can readily expand to further include: 

  • Subscriptions to streaming services and online publications 
  • Online game accounts—and in-game items associated with them 
  • Currency stored in online payment platforms 
  • Online storefronts, such as eBay, Etsy, or business websites 
  • Website domain names, whether in use or held speculatively for later resale 
  • Documents kept in cloud storage, like financial documents and ancestry research 

And like any other asset in the case of a divorce, a value will be ascribed to each digital asset and then distributed per the conditions or orders of the settlement. 

What digital assets do you have? 

Arriving at the value of specific digital assets begins with an inventory—listing all the digital assets and accounts you own, just as you would with any other monetary or physical assets like bank accounts, properties, and carsWhen you go through this process, chances are you’ll quickly find that you have hundreds if not thousands of dollars of digital assets.  

For example, we can look at the research we conducted in 2011 which found that people placed an average value of $37,438 on the digital assets they owned at the time. Now, with the growth of streaming services, digital currency, cloud storage, and more in the past ten years, that figure feels conservative. 

Above and beyond preparing for a divorce settlement, taking such an inventory of your digital assets is a wise move. One, it provides you with a clearer vision of the things you own and their worth; two, maintaining such a list gives you a basis for estate planning and determining who you would like to see receive those assets. Likewise, maintain that list on a regular basis and keep it safe. It’s good digital hygiene to do so. 

What are digital assets worth in a divorce? 

With this inventory, each asset can then have an assessed value ascribed to it. In some instances, a value will easily present itself, such as the cost of a subscription or how much money is sitting in a PayPal account. In other cases, the value will be sentimental, such as the case is with digital photos and videos. Ideally, you and your spouse will simply be able to duplicate and share those photos and videos amicably, yet it is important that you articulate any such agreement to do so. This way, a settlement can call out what is to be shared, how it will be shared, and when. 

Identify which digital assets cannot be transferred 

Not all digital assets are transferrable. Certain digital assets are owned solely in your name. In other words, you may have access to certain digital assets that cannot transfer to someone else because you do not have the rights to do so per your user agreement. This can be the case with things such as digital books, digital music, and digital shows and movies.  

In such circumstances, there may be grounds for negotiation and a “limited transfer” in the settlement, where one party exchanges one asset for another rather than splitting it equally. A case in point might be a sizeable eBook library on a device that’s in the name of one spouse. While that library can’t be split or transferred, one spouse may keep the eBook library while another spouse keeps a similarly valued asset or group of assets in return—like say a collection of physical books. 

Streaming services and divorce 

Streaming services will need to be addressed too. Be prepared to either terminate your accounts or simply have them assigned to the person in whose name they are kept. In the case of family accounts, the settlement should determine how that is handled, whether it gets terminated or similarly turned over to one spouse or the other. In all, your settlement will want to specify who takes over what streaming service and when that must occur. 

Cryptocurrencies like bitcoin and divorce 

Like dividing up investment accounts where the value of the account can vary daily, digital currencies can present challenges when spouses look to divide the holdings. Cryptocurrency valuation can be quite volatile, thus it can be a challenging asset to settle from a strict dollar standpoint.  

What’s more, given the nature of digital currencies, there are instances where an unscrupulous spouse may seek to hide worth in such currency—which is an evolving issue in of itself. This recent article, “Cryptocurrency: What to Know Before and During Divorce,” covers the additional challenges of cryptocurrency in detail, along with an excellent primer on what cryptocurrency is and how it works. 

Ultimately, cryptocurrency is indeed an asset, one that your attorney and settlement process will need to addressspecifically so that there are no complications later with the transfer or valuation of the awarded currency. 

Passwords and divorce 

With accounts changing hands, now’s the time to start fresh with a new set of passwords. What’s more, we have a tendency to reuse the same passwords over and over again, which may be known to an ex-spouse and is an inherent security risk in of itself. Change them. Even better, take this opportunity to use a password manager. A password manager can create and securely store strong, unique passwords for you, thus saving you the headache of maintaining dozens of them yourself—not to mention making you far more secure than before. 

 Seek out a legal professional 

Again, keep in mind that nothing here is legal advice. Yet, do keep these things in mind when consulting with an attorney. The reality is that we likely have thousands of dollars of what could be considered digital assets. Inventorying them and ascribing a fair market value to them along with your legal professional is the first step in a fair and just settlement.

Why Coin Miners Go Bad & How to Protect Your Tech When They Do

By Vishnu Varadaraj
coin miners

Cryptocurrency enthusiasts are flocking to the Wild West of Bitcoin and Monero to cash in on the recent gold rush. Bitcoin’s meteoric rise in value is making coin mining an appealing hobby or even a whole new careerCoin mining software is the main tool in a prospector’s belt.  

Some coin miners, also known as cryptocurrency miners, are tempted by the dark side of the industry and resort to nefarious means to harness the immense computing power needed for cryptocurrency profits. Greedy cryptocurrency criminals employ a practice called cryptojacking, stealing the computer power of unsuspecting devices to help them mine faster. Your device could be at risk at being recruited to their efforts.  

Let’s dig into how coin mining programs work, why they turn malicious, and how you can stay safe from cryptojackers. 

How Coin Mining Works 

Mining cryptocurrency takes a lot of time and computer processing power. A coin mining home setup requires a graphics processing unit (GPU) or an application-specific integrated circuit (ASIC). Coin mining software then runs off the GPU or ASIC. Each central processing unit (CPU), or the brain of the computer, plus the GPU or ASIC is referred to as a mining rig. 

Once the software is installed, the rig is ready to mine, running mathematical calculations to verify and collect new cryptocurrency transactions. Each calculation is known as a hash, and hash rates are the number of calculations that can be run per second. 

From there, casual miners may choose to join a mining pool, which is a club of miners who agree to consolidate their computing power and split the profits based on how much work each miner contributed to the output. 

Bitcoin rewards miners every 10 minutes for their effortsEach time miners solve a string of mathematical puzzles, they validate a chain of transactions, thus helping make the entire Bitcoin system more secure. Miners are paid in bitcoin and they also receive a transactional fee. 

Why Coin Mining Turns Malicious 

While coin mining typically starts off as a casual hobby, coin mining programs can turn malicious when cryptocurrency miners want to earn more without investing in boosting their own computing power. Instead, they reroute their targets computing power without asking. This is called cryptojacking. 

Mining requires incredible amounts of electricity and the more riginvolved; the more cryptocurrency can be mined. Usually, the utility bills and the cost of running coin mining software negates any profit. For example, a casual miner may have one rig devoted to mining. An average rig processes approximately 500 hashes per second on the Monero network (a type of cryptocurrency). However, 500 hashes per second translates to less than a dollar per week in traditional, or fiat, currency. 

Greedy cryptocurrency criminals recruit CPU soldiers to their mining army to improve their hash rate. To do so, criminals download coin mining software to a device and then program it to report back to their server. The device’s thinking power is diverted from the owner and funneled straight to the criminal’s server that now controls it. Compromised devices run considerably slower and can overheat, and the strain on the device can eventually destroy it. 

How to Stay Safe from Cryptojacking 

Cryptojackers are not your everyday thieves. Their target is your CPU power, and they employ devious methods to funnel it for their own use. Luckily, there are a few easy ways to thwart their efforts: 

1. Beware of phishing 

Personal devices are often infected through phishing within emails and texts. There are many tell-tale signs of a phishing message. For example, they are often poorly written and use language that indicates that the sender wants a hasty response. Also, phishing attempts often charade as official organizations, like banks and credit card companies. If you are ever suspicious of an email or text, do not open any of the links and do not reply. Instead, contact the organization’s customer support to verify the legitimacy of the message. 

2. Use ad blockers 

Another way miners gain access to personal devices is by camouflaging malicious code in pop-up ads. An easy way to avoid being cryptojacked is to simply never click on these ads. Or even better, install an ad blocker to help eliminate the risk. 

3. Connect to a VPN 

Public wi-fi and poorly protected networks present a vulnerable entry point for cybercriminals to hack into your devices. Cybercriminals often attempt to download software remotely to your laptop, desktop, or mobile device to reroute its computing power for their own selfish gains. Always connect to a VPN like McAfee Safe Connect VPN to safely surf unsecure networks. 

4. Run antivirus software 

Cryptojacking code is inconspicuous and generally hidden in legitimate code. Antivirus software, such as McAfee Total Protection, is a recommended way to proactively scan for malware and even identify fraudulent websites. McAfee WebAdvisor has a Chrome extension that specifically blocks cryptojackers. 

5. Monitor your devices 

Be aware of the signs your devices have been cryptojacked. For example, monitor any changes in the speed of your devices and check out your utility bills for dramatic spikes. By remaining vigilant with these tips, you will keep your devices safe from cryptocurrency miners gone rogue.
