According to BleepingComputer, SIM swappers have adapted their techniques to steal phone numbers by transferring them onto new eSIM cards.
These eSIMs, embedded in mobile device chips, function like physical SIM cards but offer remote reprogramming capabilities.
Exploiting eSIMs by Cybercriminals
Embedded Subscriber Identity Modules (eSIMs) function similarly to physical SIM cards but are digitally stored on mobile device chips. They can be reprogrammed remotely and facilitate various functionalities such as activation and deactivation through QR code scans provided by service providers.
The report also highlights a surge in eSIM exploitation by SIM swappers worldwide, as noted by F.A.C.C.T., a Russian cybersecurity firm. By exploiting eSIM functionalities, criminals circumvent security measures to take control of phone numbers, resulting in unauthorized access to sensitive accounts.
Attackers’ Approach
Instead of relying on social engineering or insider assistance, attackers exploit vulnerabilities in mobile accounts using stolen credentials. They initiate number porting to a new device by generating QR codes within hijacked accounts, effectively seizing control of the victim’s number.
Protective Measures
Furthermore, once cybercriminals obtain the victim’s number, they exploit it for fraudulent activities, including accessing banking services and messenger apps.
To mitigate these risks, users should use strong passwords, enable two-factor authentication, and consider additional security measures like physical keys or authenticator apps for critical accounts.
In summary, the emergence of eSIM technology has inadvertently provided SIM swappers with new opportunities for exploitation. As cyber threats evolve, users must remain vigilant and implement robust security practices to protect their digital assets and personal information.

Since its commencement in 2009, Bitcoin, the world’s oldest cryptocurrency, has attracted the attention of suckers, investors, scammers and more lately, controllers.

For numerous of its epigones, Bitcoin isn’t just a new form of currency but a groundbreaking technology that introduced the world to the conception of decentralized currencies and established the bedrock for an entirely new type of frugality the cryptocurrency request.

For others, it was a way to make a quick buck, and while some of these early investors did manage to join the gang of Bitcoin millionaires, numerous further misplaced hundreds or indeed thousands of bones
trying to prognosticate its price movements.

Bitcoin’s Price History

Bitcoin has been the subject of numerous price prognostications, some of them extreme.

specially, Cathie Wood, CEO of Ark Invest, prognosticated that Bitcoin could reach an astounding$1.48 million by 2030. elderly critic Nicholas Sciberras from Collaborative Shift points out that this vaticination reflects wide surprise at Bitcoin’s gradational rise.

“ It’s delicate to put any price target out there, as the sky could come the limit depending on the position of relinquishment and external factors in the request, ” he says.

Bitcoin has come a long way since its first recorded price of lower than a cent. As of December 20, 2023, one Bitcoin was worth roughly$ 42,000. The idea that Bitcoin could one day be worth a million bones
per unit, as Sciberras points out, “ really shows how far we ’ve come ”.

While great highs are possible, so too are disastrous lows.

Spoons
Bitcoin’s trip started in 2009, with the release of the Bitcoin white paper by creator Satoshi Nakamoto.

The early times of Bitcoin were marked by steady growth and ages of rapid-fire price appreciation, known as “ bull runs. ” One of the topmost bull runs saw the price of BTC reach$ 69,000 in November 2021. still, there were also ages of query, as Sciberras points out.

“ During 2014 and 2017 we saw numerous Bitcoin ‘ spoons ’ proposed that resolve the Bitcoin community, ” he says. Hard spoons are changes to the underpinning protocol of the blockchain network that resolve a cryptocurrency into two.

These spoons represented pivotal junctures in Bitcoin’s history, with colorful coalitions in the community trying to change BTC’s direction. Despite heated debates, and a number of spoons, Bitcoin has persisted in its current format.

“ Bitcoin surviving these attempts to change it’s a core contributor to where BTC is now, adding its confidence and adaptability, ” Sciberras says.

“ It has survived numerous storms and attempts to change it, with Bitcoin spoons now a distant memory, combining for lower than 1 of Bitcoin’s total request cap. ”

Bitcoin Halving
Another defining point of Bitcoin’s price history is the halving event, which happens roughly every four times and reduces the rate at which new coins are created. The coming halving is anticipated to do eventually in early tomid-2024.

“ We ’ve seen Bitcoin’s price significantly increase a time before the halving and a time after, ” Sciberras says.
numerous investors view the halving event as one of the most significant factors that affects Bitcoin’s price. still, Sciberras is wary.

“ The jury is still out on how priced- in the halving is, or how important the event is in the grand scheme of Bitcoin’s price line, ” he says.

“ There’s a proposition that the four- time halving event isn’t as significant as numerous suppose and that, rather, its alignment with external liquidity cycles is what makes it appear like a detector for upward price movement. ”

How Will Bitcoin Perform in 2024?

Bitcoin’s performance in 2024 depends on a variety of implicit bullish and bearish catalysts. multitudinous factors, similar as institutional relinquishment, the halving, nonsupervisory changes and macroeconomic trends will impact the price of Bitcoin in 2024.

During 2023, the crypto assiduity was rocked by a series of enforcements that shook confidence in the sector. TheU.S. Commodity Futures Trading Commission filed civil enforcement action against crypto exchange, Binance, and its author and CEO Changpeng “ CZ ” Zhao.

still, in November, Binance settled with theU.S. Treasury and Department of Justice, with CZ agreeing to step down and hand over the arm as part of the deal.

Sciberras notes that, most importantly Binance wasn’t indicted of misusing client finances and “ did not see a bank run on the exchange. ”

“ This was one of the stylish issues the request could ’ve hoped for, and crypto prices rallied as a result, ” he says.

“ Binance was a massive argentine pall swimming over crypto, and the agreement is a huge green flag heading into 2024. ”

Interest Rates and Bitcoin
Chair of theU.S. Federal Reserve, Jerome Powell, has indicated that the central bank may have reached the peak of its rate hike cycle, which Sciberras thinks could be a catalyst for a Bitcoin rally in 2024.

When interest rates stabilize or fall, cryptocurrencies similar as Bitcoin can offer an seductive place for investors to situate capital due to its perceived barricade against traditional fiscal systems and adding failure — especially as the halving approaches in May.

“ Estimates read three 25- base- point rate cuts in 2024, a more aggressive outlook than what they’ve preliminarily gestured, ” Sciberras says.

Sciberras recommends investors keep an eye on affectation from the particular consumption expenditures( PCE) price indicator, as Powell has left the door open for farther rate rises if it begins to creep back over.

What Does the Future Hold for Bitcoin?

When it comes to prognosticating the future of Bitcoin, there are two implicit issues to consider the bull and the bear case.

The Bull Case

Sciberras says a bullish future for Bitcoin may depend on the soundness, or warrant thereof, of traditional banking fabrics.

“ There are serious issues in the global frugality, with theU.S. facing a banking extremity and growing debt scores, ” Sciberras says.

“ There were multiple bank failures in 2023, but numerous forget the beginning problem of these failures still exists. ”

still, the government may be forced to step in to give encouragement or publish further plutocrat, If bank failures continue in 2024. This would further cheapen theU.S. bone, analogous to what passed during the Covid- 19 epidemic.

“ In this script, Bitcoin’s part as a known, fair and flexible asset with a fixed force where the rules of the game aren’t fluently changed could come seductive, ” Sciberras says.

Bitcoin inventions
Sciberras also points to the increased demand for block space on Bitcoin’s network due to recent inventions, similar as ordinals and BRC- 20 commemoratives, as positive developments.

The advanced demand, mileage and freights for miners could help palliate enterprises over Bitcoin’s long- term security budget. The growing relinquishment of the Lightning Network, a subcaste on Bitcoin that enables briskly deals, could affect in Bitcoin getting further of a payment system rather than just a store of value.

still, it could increase its overall mileage and come more ‘ plutocrat ’ like — helping it reach those lofty price targets, ” Sciberras adds, “ If Bitcoin can continue making progress and relinquishment in the payment front.

“ We’re seeing early signs of Lightning relinquishment. Lightning Network’s total payments grew 1,212 over the once two times. We’re also seeing Lightning prostrating distribution hurdles with raised support. ”

Institutional Relinquishment
In June of 2023, BlackRock, the world’s largest asset director, filed plans to start a spot exchange- traded fund( ETF) for BTC. Multiple other institutions followed suit, with WisdomTree, ARK Invest and others lodging their first operation or streamlining being operations shortly after BlackRock’s advertisement.

These operations were part of lesser institutional relinquishment of Bitcoin throughout the remainder of 2023, driving the price to a high of nearly$ 45,000 in December.

There are now nearly 10 operations with the SEC, and there’s a limited quantum of time before a decision must be made to either authorize or deny them. January 10, 2024, is listed as the decision date for BlackRock’s operation.

Presently, the only Bitcoin ETFs approved for trading in theU.S. trade in Bitcoin futures. Futures are a complex secondary instrument grounded on the unborn price of an asset.

Sciberras lists a spot Bitcoin ETF blessing as a crucial factor impacting Bitcoin’s price in 2024. It would not only necessitate physical Bitcoin purchases which would potentially lift prices but it would also add a considerable air of legality to cryptocurrency more astronomically.

“ The( blessing) could channel between$ 30 billion to$ 300 billion into Bitcoin, ” he says.

Sciberras also cites the Financial Accounting Standards Board’s( FASB) new digital asset reporting rules, set to take effect in December 2024, which will ease rules around the reporting and holding of cryptocurrencies for companies. These new norms remove a significant handicap for companies holding Bitcoin on their balance distance.

The Bear Case

Every investment has implicit downsides, and Bitcoin is no exception.

Sciberras says on the negative side of the tally, there are enterprises over Bitcoin’s long- term security, given the block price will continue to drop. He adds that the spot Bitcoin ETF operations also pose a implicit threat if they’re rejected, creating a short- term sell- off of BTC.

also there’s the contentious debate about ‘ eulogies ’ on the Bitcoin blockchain. While Sciberras acknowledges their eventuality in generating sustainable freights for the protocol in the long- term, especially as further Bitcoins circulate and miner reliance on freights increases, he also notes the disunited opinions within the community regarding their impact on the network’s functionality.

specially, a reputed original Bitcoin inventor, Luke Dashjr, markers eulogies as “ spam. ” He argues that they clog the network, complicating the mining process and the network’s overall support. This difference in perspective sets the stage for a implicit ideological clash within the Bitcoin community.

Environmental Considerations
Environmental fall- eschewal is another concern.
“ There are continued attacks on Bitcoin’s environmental impacts, with the White House proposing a duty of over to 30 on Bitcoin miners in theU.S., ” Sciberras says.

still, it could hang its price action, If Bitcoin continues to be blamed due to its energy consumption.

“ The worst- case script is we see Europe try to introduce a ban on( evidence of work), which was tried in 2022 but was fleetly struck down. ”

Bitcoin uses a evidence of work confirmation system. evidence of work as opposed to evidence of stake — is the most energy ferocious confirmation system that cryptocurrencies can use.

Political Issues
A swing in sentiment against Bitcoin and cryptocurrency by governments could also drop prices.

“ TheU.S. is getting incredibly hostile towards cryptocurrency and Bitcoin, ” Sciberras says.

If Bitcoin threatens countries ’ monopoly on plutocrat due to wide relinquishment, governments could move to circumscribe it.

Sciberras points to a recent bill introduced in theU.S. to expand the Bank Secrecy Act and put more strict reporting conditions for digital currency deals, including those with unhosted holdalls
, as an area for concern.

“ In its current form, this legislation would cripple theU.S. crypto assiduity, ” he says.

The counteraccusations ofanti-money laundering( AML) and Know Your client( KYC) laws also worry investors. Sciberras mates out the specific challenges of administering high reporting conditions on transfers to private, tone- hosted holdalls
.

“ AML laws remain a big battlefield and could hang the assiduity as compliance could be extremely delicate, ” Sciberras says.

Is Bitcoin a Worthwhile Investment?

Investing in Bitcoin comes with its share of prices and pitfalls, and understanding these is crucial to making an informed decision.

Overall, Sciberras is auspicious about Bitcoin’s future.

“ Looking into 2024 and further, I ’m tête-à-tête veritably long- term bullish on Bitcoin, ” he says, citing the macroeconomic background, the forthcoming halving in May, the bettered development of scalability within the Lightning network and the implicit BTC ETF.

still, Bitcoin’s future is n’t without implicit hurdles.

still, also it could put pressure on Bitcoin’s long- term sustainability, ” Sciberras says, “ If Bitcoin continues to be targeted by governments and its energy consumption is farther politicized.

One of the significant long- term enterprises for Bitcoin is its security in the face of a dwindling block price.

still, or figure profit is shy to incentivize miners to upgrade their tackle and mine new Bitcoins, security could drop and hang the network, “ If there’s lackluster relinquishment and demand for Bitcoin.

anybody can explain the how to calculate the markup?

We ’re lower than a month down from the launch of Samsung’s rearmost flagship smartphones, the Galaxy S24 range, If rumors are to be believed. Over on X, the platform formerly known as Twitter, leaker Evan Blass has participated what appears to be an early look at a preamble to the coming Galaxy Unpacked that says “ Galaxy AI is coming ” on January 18th at 3AM KST. That translates to 1PM ET on January 17th, in line with a preliminarily reported date for the launch. Blass also participated a blurted spec distance for the three bias which confirms numerous of their preliminarily bruited features.

According to the spec distance, Samsung is formerly again planning to offer three models as part of the range. There’s the standard Galaxy S24, with a6.2- inch screen, the S24 Plus which goes up to6.7 elevation, and the S24 Ultra which has a screen6.8 elevation in size. The spec distance lists all three as being powered by Qualcomm’s rearmost flagship processor, the Snapdragon 8 Gen 3, although rumors suggest that outside the US, Canada, and China, the phones will be powered by Samsung’s own Exynos 2400.

For cameras, the S24 Ultra looks to have a 200- megapixel main detector( same as the S23 Ultra), while the S24 and S24 Plus top out at 50 megapixels. The S24 Ultra’s blowup lens will offer a drone of over to 10x, while the other two models can go up to 3x. Other bruited camera specs include 10- megapixel blowup detectors on the S24 and S24 Plus, and a brace of blowup lenses on the Ultra — one 50- megapixel with a 5x optic drone( which can reportedly be cropped to offer 10x drone) and one 10- megapixel with 3x optic drone. All three phones are bruited to have 12- megapixel ultrawides and 12- megapixel selfie cameras.

In terms of batteries, according to the blurted spec distance the S24 has a 4,000 mAh capacity, the S24 Plus 4,900 mAh, and the Ultra 5,000 mAh. There’s IP68 water and dust resistance across the range, and the spec distance confirms that the S24 Ultra will use titanium in its construction, versus aluminum in the S24 and S24 Plus.

Images posted by Arsène Lupin on X have you covered, If you want a complete look at what the phones look like in numerous colors and from all angles. The three phones have a veritably analogous look to their 2023 forerunners, although the S24 Ultra reportedly has a fully flat screen this time around according to earlier leaks, jilting the slight angles seen on the S23 Ultra. Available colors include black, argentine, grandiloquent, and unheroic, however there may be fresh colors available via Samsung’s own store.

Overall it looks like it could be an iterative time for Samsung’s flagship lineup from a tackle perspective. But from a software perspective effects could be a lot more intriguing, if the “ Galaxy AI is coming ” tease in Blass’s preamble timekeeper is anything to go by. Last month, Korea Times reported that Samsung’s generative AI model, dubbed “ Gauss, ” could be integrated into the forthcoming Galaxy S24 lineup and run natively on device to induce and edit images, compose emails, epitomize documents, and help with coding. Samsung has also spoken about using AI to restate phone calls in real time. The features could offer Samsung an intriguing edge as it attempts to contend with Google’s rearmost AI- invested Pixel.

Tax leakages impact not only the country but put extra pressure on our working class. Loopholes lead to borrowing! Avoid debts, pay tax! #BePakistaniPayTaxes

Pakistan has one of the lowest tax-paying populations in the world with only 1 percent of the citizens filing their tax returns. .

Paying tax is not punishment it is a source through which government finances its activities.

After 70 years of existence, the country has less than two million income tax filers, one of the lowest tax-to-GDP ratios in the world, and a tax system which riddled with inequity and corruption. #BePakistaniPayTaxes
