After researchers unmasked a prolific SMS scammer, a new operation has emerged in its wake

If you, like practically anyone else with a cell phone in the U.S. and beyond, have received a scam text message about an unpaid toll or undelivered mail item, there’s a good chance you have been targeted by a prolific scamming operation.

The scam isn’t particularly complex, but it has been highly effective. By sending spam text messages that look like genuine notifications for popular services, from postal deliveries to local government programs, unsuspecting victims click a link that loads a phishing page, they enter their credit card details, and that information is swiped and used for fraud.

During a period of seven months in 2024, the scam netted at least 884,000 stolen credit card details, allowing scammers to cash in on their victims’ accounts. Some victims lost thousands of dollars in the scam, researchers say.

But a series of opsec mistakes ultimately led security researchers and investigative journalists to the real-world identity of the maker of the scamming software, Magic Cat, who researchers say goes by the handle Darcula.

As revealed by the Oslo-headquartered security firm Mnemonic and reported in tandem by Norwegian media earlier this year, behind the fluffy cute cat in Darcula’s profile photos is a 24-year-old Chinese national named Yucheng C.

The researchers say Yucheng C. develops Magic Cat for his hundreds of customers, who use the software to launch their own SMS text message scam campaigns at their victims.

Soon after he was unmasked, Darcula went dark and his scam operation has not seen any updates since, leaving his customers in the lurch. But in its wake, a new operation has emerged and is already vastly outpacing its predecessor.

Researchers are now sounding the alarm on the new fraud operation, Magic Mouse, which rose from the ashes of Magic Cat.

Ahead of sharing new findings at the Def Con security conference in Las Vegas on Friday, Harrison Sand, an offensive security consultant at Mnemonic, told TechCrunch that Magic Mouse has been surging in popularity since the demise of Darcula’s Magic Cat.

Sand also warned of the operation’s growing ability to steal people’s credit cards on a massive scale.

During their investigation, Mnemonic found photos from inside the operation posted in a Telegram channel that Darcula administered, showing a line-up of credit card payment terminals and videos showing racks with dozens of phones used for automating the sending of messages to victims.

The scammers use the card details in mobile wallets on phones and conduct payment fraud, laundering their funds into other bank accounts. Some of the phones had mobile wallets overflowing with other people’s stolen cards, ready to be used for mobile transactions.

Sand told TechCrunch that Magic Mouse is already responsible for the theft of at least 650,000 credit cards a month.

While evidence suggests Magic Mouse is an entirely new operation, coded by new developers and likely unrelated to Darcula, much of Magic Mouse’s success stems from the new operators stealing the phishing kits that made its predecessor’s software so popular. Sand said these kits contain hundreds of phishing sites that Magic Cat used to mimic the legitimate web pages of major tech giants, popular consumer services, and delivery firms, all designed to trick victims into handing over their credit card details.

But despite the prolific nature of Magic Cat and, now, Magic Mouse, and their ability to net millions of dollars in stolen funds from consumers, Sand told TechCrunch in a call that law enforcement is not looking beyond a few scattered reports of fraud or at the wider operation behind the scheme.

Instead, Sand said, it is the tech companies and financial giants who shoulder much of the responsibility for allowing these scams to exist and thrive, and for not making it more difficult for scammers to use stolen cards.

As for anyone who receives a suspicious text, ignoring an unwanted message might be the best policy.

Pintarnya raises $16.7M to power jobs and financial services in Indonesia

Pintarnya, an Indonesian employment platform that goes beyond job matching by offering financial services along with full-time and side-gig opportunities, said it has raised a $16.7 million Series A round.

The funding was led by Square Peg with participation from existing investors Vertex Venture Southeast Asia & India and East Ventures.

Ghirish Pokardas, Nelly Nurmalasari, and Henry Hendrawan founded Pintarnya in 2022 to tackle two of the biggest challenges Indonesians face daily: earning enough and borrowing responsibly.

“Traditionally, mass workers in Indonesia find jobs offline through job fairs or word of mouth, with employers buried in paper applications and candidates rarely hearing back. For borrowing, their options are often limited to family/friend or predatory lenders with harsh collection practices,” Henry Hendrawan, co-founder of Pintarnya, told TechCrunch. “We digitize job matching with AI to make hiring faster and we provide workers with safer, healthier lending options — designed around what they can reasonably afford, rather than pushing them deeper into debt.”

Around 59% of Indonesia’s 150 million workforce is employed in the informal sector, highlighting the difficulties these workers encounter in accessing formal financial services because they lack verifiable income and official employment documentation.

Pintarnya tackles this challenge by partnering with asset-backed lenders to offer secured loans, using collateral such as gold, electronics, or vehicles, Hendrawan added.

Since its seed funding in 2022, the platform currently serves over 10 million job seeker users and 40,000 employers nationwide. Its revenue has increased almost fivefold year-over-year and expects to reach break-even by the end of the year, Hendrawn noted. Pintarnya primarily serves users aged 21 to 40, most of whom have a high school education or a diploma below university level. The startup aims to focus on this underserved segment, given the large population of blue-collar and informal workers in Indonesia.

“Through the journey of building employment services, we discovered that our users needed more than just jobs — they needed access to financial services that traditional banks couldn’t provide,” said Hendrawan. “We digitize job matching with AI to make hiring faster and we provide workers with safer, healthier lending options — designed around what they can reasonably afford, rather than pushing them deeper into debt.”

While Indonesia already has job platforms like JobStreet, Kalibrr, and Glints, these primarily cater to white-collar roles, which represent only a small portion of the workforce, according to Hendrawan. Pintarnya’s platform is designed specifically for blue-collar workers, offering tailored experiences such as quick-apply options for walk-in interviews, affordable e-learning on relevant skills, in-app opportunities for supplemental income, and seamless connections to financial services like loans.

The same trend is evident in Indonesia’s fintech sector, which similarly caters to white-collar or upper-middle-class consumers. Conventional credit scoring models for loans, which rely on steady monthly income and bank account activity, often leave blue-collar workers overlooked by existing fintech providers, Hendrawan explained.

When asked about which fintech services are most in demand, Hendrawan mentioned, “Given their employment status, lending is the most in-demand financial service for Pintarnya’s users today. We are planning to ‘graduate’ them to micro-savings and investments down the road through innovative products with our partners.”

The new funding will enable Pintarnya to strengthen its platform technology and broaden its financial service offerings through strategic partnerships. With most Indonesian workers employed in blue-collar and informal sectors, the co-founders see substantial growth opportunities in the local market. Leveraging their extensive experience in managing businesses across Southeast Asia, they are also open to exploring regional expansion when the timing is right.

“Our vision is for Pintarnya to be the everyday companion that empowers Indonesians to not only make ends meet today, but also plan, grow, and upgrade their lives tomorrow … In five years, we see Pintarnya as the go-to super app for Indonesia’s workers, not just for earning income, but as a trusted partner throughout their life journey,” Hendrawan said. “We want to be the first stop when someone is looking for work, a place that helps them upgrade their skills, and a reliable guide as they make financial decisions.”

OpenAI warns against SPVs and other ‘unauthorized’ investments

In a new blog post, OpenAI warns against “unauthorized opportunities to gain exposure to OpenAI through a variety of means,” including special purpose vehicles, known as SPVs.

“We urge you to be careful if you are contacted by a firm that purports to have access to OpenAI, including through the sale of an SPV interest with exposure to OpenAI equity,” the company writes. The blog post acknowledges that “not every offer of OpenAI equity […] is problematic” but says firms may be “attempting to circumvent our transfer restrictions.”

“If so, the sale will not be recognized and carry no economic value to you,” OpenAI says.

Investors have increasingly used SPVs (which pool money for one-off investments) as a way to buy into hot AI startups, prompting other VCs to criticize them as a vehicle for “tourist chumps.”

Business Insider reports that OpenAI isn’t the only major AI company looking to crack down on SPVs, with Anthropic reportedly telling Menlo Ventures it must use its own capital, not an SPV, to invest in an upcoming round.

Meta partners with Midjourney on AI image and video models

Meta is partnering with Midjourney to license the startup’s AI image and video generation technology, Meta Chief AI Officer Alexandr Wang announced Friday in a post on Threads. Wang says Meta’s research teams will collaborate with Midjourney to bring its technology into future AI models and products.

“To ensure Meta is able to deliver the best possible products for people it will require taking an all-of-the-above approach,” Wang said. “This means world-class talent, ambitious compute roadmap, and working with the best players across the industry.”

The Midjourney partnership could help Meta develop products that compete with industry-leading AI image and video models, such as OpenAI’s Sora, Black Forest Lab’s Flux, and Google’s Veo. Last year, Meta rolled out its own AI image generation tool, Imagine, into several of its products, including Facebook, Instagram, and Messenger. Meta also has an AI video generation tool, Movie Gen, that allows users to create videos from prompts.

The licensing agreement with Midjourney marks Meta’s latest deal to get ahead in the AI race. Earlier this year, CEO Mark Zuckerberg went on a hiring spree for AI talent, offering some researchers compensation packages worth upwards of $100 million. The social media giant also invested $14 billion in Scale AI, and acquired the AI voice startup Play AI.

Meta has held talks with several other leading AI labs about other acquisitions, and Zuckerberg even spoke with Elon Musk about joining his $97 billion takeover bid of OpenAI (Meta ultimately did not join the offer, and OpenAI denied Musk’s bid).

While the terms of Meta’s deal with Midjourney remain unknown, the startup’s CEO, David Holz, said in a post on X that his company remains independent with no investors; Midjourney is one of the few leading AI model developers that has never taken on outside funding. At one point, Meta talked with Midjourney about acquiring the startup, according to Upstarts Media.

Midjourney was founded in 2022 and quickly became a leader in the AI image generation space for its realistic, unique style. By 2023, the startup was reportedly on pace to generate $200 million in revenue. The startup sells subscriptions starting at $10 per month. It offers pricier tiers, which offer more AI image generations, that cost as much as $120 per month. In June, the startup released its first AI video model, V1.

Meta’s partnership with Midjourney comes just two months after the startup was sued by Disney and Universal, alleging that it trained AI image models on copyrighted works. Several AI model developers — including Meta — face similar allegations from copyright holders, however, recent court cases pertaining to AI training data have sided with tech companies.
