MongoDB shares cratered more than 20% after the database software maker shared weak guidance that signaled a slowdown in growth.

For the fiscal 2026 year, the company said it expects adjusted earnings to range between $2.44 to $2.62 per share and revenue of $2.24 billion to $2.28. Analysts were expecting EPS of $3.34 and $2.32 billion in revenue.

The weak guidance stems from slower growth in the company’s Atlas cloud-based database service. The revenue projection would imply 12.7% growth, the slowest for the company going back to its 2017 stock market debut.

Finance chief Srdjan Tanjga said during an earnings call that the company is seeing slower-than-expected growth in new applications harnessing its Atlas cloud-based database service. However, MongoDB is beefing up hiring and going after deals with larger companies.

For the fiscal first quarter, MongoDB forecasted 63 cents to 67 cents in adjusted earnings per share on $524 million to $529 million in revenue. Analysts polled by LSEG had expected EPS of 62 cents and revenue of $526.8 million.

Citing MongoDB’s weak outlook and slowdown in growth, Wells Fargo analyst Andrew Nowinski downgraded shares to equal weight and lowered his price target.

“With a smaller pool of multi-year deals, we believe it will be difficult to significantly outperform expectations in FY26 and therefore expect shares to remain range-bound,” he wrote.

MongoDB’s outlook offset stronger-than-expected fourth-quarter earnings. The company reported earnings of $1.28 per share, excluding items, on $548 million in revenue. Analysts polled by LSEG had anticipated EPS of 66 cents and $520 million in sales. Revenues rose 20% from a year ago.

MongoDB gained 1,900 customers in the quarter, reflecting a total of 54,500.

Alibaba shares surged on Wednesday after the Chinese behemoth revealed a new reasoning model it claims can rival DeepSeek’s global blockbuster R1.

Hong Kong-listed shares of Alibaba ended the Thursday session up 8.39% — hitting a new 52-week high — with the company’s New York-trading stock rising around 2.5% in premarket deals. Alibaba shares have gained nearly 71% in Hong Kong in the year to date.

The Chinese giant on Thursday unveiled QwQ-32B, its latest AI reasoning model, which it said “rivals cutting-edge reasoning model, e.g., DeepSeek-R1.”

Alibaba’s QwQ-32B operates with 32 billion parameters compared to DeepSeek’s 671 billion parameters with 37 billion parameters actively engaged during inference — the process of running live data through a trained AI model in order to generate a prediction or tackle a task.

Parameters are variables that large language models (LLMs) — AI systems that can understand and generate human language — pick up during training and use in prediction and decision-making. A lower volume of parameters typically signals higher efficiency amid increasing demand for optimized AI that consumes fewer resources.

Alibaba said its new model achieved “impressive results” and the company can “continuously improve the performance especially in math and coding.”

Both established and emerging AI players around the world are racing to produce more efficient and higher-performance models since the unexpected launch of DeepSeek’s revolutionary R1 earlier this year.

Chinese firms have been doubling down on the technology with Alibaba investing in AI after debuting its first model in 2023. The strength of the company’s cloud Intelligence unit was a key contributor to Alibaba’s sharp profit hike in the December quarter.

“Looking ahead, revenue growth at Cloud Intelligence Group driven by AI will continue to accelerate,” Alibaba CEO Eddie Wu said at the time.

Optimism surrounding AI developments could lead to large gains for Alibaba stock and set the company’s earnings “on a more upwardly-pointing trajectory,” Bernstein analysts said.

“The pace of innovation is incredibly fast right now. It’s really good for the world to see this happening,” Futurum Group CEO Dan Newman told CNBC’s “Squawk Box Europe” on Thursday. “When DeepSeek came out, it made everyone sort of question, was OpenAi the final answer? Would the incumbents, the Microsofts, the Googles, or the Amazons that have all made massive investments win?”

He stressed that the large language models were increasingly “becoming commoditized” as developers look to drive down costs and improve access to users.

“As we see this more efficiency, this cost coming down, we’re also going to see use going off. The training era, which is what Nvidia really built its initial AI boom off, was a big moment,” Newman said. “But the inference, the consumption of AI, is really the future and this is going to exponentially increase that volume.”

An expanding network of cybercrime marketplaces is making it easier than ever to become a professional fraudster, posing unprecedented cybersecurity threats worldwide, experts warn.

Cybercriminals are often portrayed in popular media as rogue and highly skilled individuals, wielding coding and hacking abilities from a dimly lit room. But such stereotypes are becoming outdated. 

“Looking back to the 1990s and early 2000s, you needed to have a reasonable level of technical competence to pull off these types of crimes,” Nicholas Court, assistant director of Interpol’s Financial Crime and Anti-Corruption Centre, tells CNBC. 

Today, the barriers to entry have come down “quite significantly,” Court said. For example, obtaining personal data, such as email addresses, and sending them spam messages en masse — one of the oldest online scams in the book — has never been easier.

Cybersecurity experts say the change is due to advances in scam technology and the growth of organized online markets where cybercrime expertise and resources are bought and sold. 

Examples of CaaS include ransomware and hacking tools, botnets for rent, stolen data, and anything else that may aid cybercriminals in their illicit activities.

“The availability of these services certainly helps in enabling more cybercriminals, allowing them to scale up and sophisticate their crime while reducing the technical expertise required,” Burnside said. 

CaaS is often hosted on markets in the “darknet” — a part of the internet that uses encryption technology to protect the anonymity of users.

Examples include Abacus Market, Torzon Market and Styx, though the top markets often change as authorities shut them down and new ones emerge. 

Burnside adds that the criminal gangs operating CaaS services and markets have begun to operate like “legitimate organizations in their structure and processes.”

Meanwhile, vendors on these illicit exchanges tend to accept payments only in cryptocurrency in attempts to remain anonymous, obscure proceeds and evade detection. 

Silk Road, an infamous dark web marketplace that was shut down by law enforcement in 2013, is recognized by many as one of the earliest large-scale applications of cryptocurrency.

Chainalysis data shows that vendors on Huione Guarantee have processed a staggering $70 billion in crypto transactions since 2021. Meanwhile, Elliptic, another blockchain analytics firm, estimates that Huione Group entities have received at least $89 billion in crypto assets, making it “the largest ever illicit online marketplace.“

The platform advertises and directs potential buyers to vendor groups on Telegram that offer everything from scam technology and money laundering to escort services and illicit goods. 

Judging from the scale and volume of the transactions on Huione Guarantee, it is likely leveraged by numerous organized criminal groups, according to Andrew Fierman, head of national security intelligence at Chainlaysis.

However, he adds that the many services don’t cost much money, providing a low barrier to entry and access point into cybercrime for “anyone with internet connection.” 

According to Chainalysis, individuals looking to facilitate “romance” or investment scams may be able to purchase the necessary tools and services on Huione for just a couple of hundred dollars. Costs can reach thousands of dollars, depending on the level of complexity they are looking to execute.

Investing or romance scams involve a fraudster building a relationship with a victim via social media or dating apps, intending to con them out of money through a sham investment opportunity.

A scammer attempting to pull off this type of scam might shop Huione Guarantee for a portfolio of potential victims’ data, such as phone numbers; old social media accounts that appear to be from real people; and AI-powered facial and voice manipulation software, which can be used by a scammer to digitally disguise themselves. 

Other vendors on the site offer services related to the creation of fake investment and gambling platforms. Fiermen says scammers often deceive victims into depositing money on such platforms.

In a disclaimer on its website, the platform says it does not participate in or understand its customers’ specific businesses and is responsible only for guaranteeing payments between buyers and sellers, according to a CNBC translation of the Chinese-language statement.

According to Fierman, Huione Guarantee’s activity appears to be concentrated in Cambodia and China, but there’s evidence that other platforms are emerging. 

Last year, Hong Kong police reported that a finance worker at a multinational firm had been tricked into paying out $25 million to fraudsters using deepfake technology to pose as the company’s chief financial officer in a video conference call.

“This would have been completely impossible to pull off just a few years ago, even for criminals with technical skills, and now it is a viable attack even for those without,” added NetSkope’s Burnside.

Meanwhile, cybersecurity experts told CNBC that AI tools can be used to enhance phishing and social engineering scams, helping to write more personalized and human-like messages. 

“It has become child’s play to create really convincing fake emails, audio notes, images or videos designed to scam and trick victims,” said Burnside, noting that dark variants of legitimate generative AI tools continue to find their way into dark markets. 

Meanwhile, new tools are emerging, such as “dark web monitoring,” which can track cybercrime markets and underground forums for leaked or stolen data, including credentials, financial data, and intellectual property.

It’s “never been easier” to commit cybercrime, so it’s crucial to prioritize cybersecurity by investing in technological solutions and enhancing employee awareness, Leow said.
