Telegram Closes Two Significant Black Market Activities

wpengine on May 18, 2025

Telegram Takes Action Against $54.6 Billion Black Market Activities

Brief Overview

Telegram has closed down two prominent black markets: Xinbi Guarantee and Huione Guarantee.
These platforms were responsible for facilitating more than AU$54.6 billion in illegal transactions since 2021.
They were recognized as central locations for cybercriminals, fraudsters, and money laundering activities.
Huione Guarantee is associated with the Cambodia-based Huione Group, which is also connected to North Korean cybercrime.
The U.S. authorities have blacklisted Huione Group for its support of malicious cyber actors.
This closure represents a major setback for global online fraud and digital crime networks.

Telegram shuts down two significant black market platforms

Telegram’s Fight Against Cybercrime Networks

Telegram, the cloud-based messaging service, has taken significant steps by shutting down two infamous black markets—Xinbi Guarantee and Huione Guarantee—both of which were operating openly on its platform. These Chinese-language services were notorious for enabling cybercrime, providing opportunities for stolen data trading, money laundering, and even telecom infrastructure for scammers.

Telegram asserted that such unlawful activities breach its terms of service and are eliminated as soon as they are detected. This action underscores an increasing commitment by technology platforms to combat illegal activities that occur in plain sight.

AU$54.6 Billion in Illegal Transactions

As per the blockchain analytics company Elliptic, Xinbi Guarantee and Huione Guarantee jointly facilitated over US$35 billion (approximately AU$54.6 billion) in transactions since 2021. This far exceeds the volume of the infamous dark web marketplace Silk Road, which was shut down by the FBI in 2013 after facilitating around US$1.2 billion in drug-related transactions.

“This is a significant setback for online fraudsters who depended on these markets for stolen data, laundering services, and telecom infrastructure,” commented Elliptic.

What Were Xinbi and Huione Guarantee?

Xinbi Guarantee and Huione Guarantee functioned as escrow services and transaction intermediaries within illicit Telegram groups. These offerings were utilized by cybercriminals to conduct large-scale fraudulent schemes, including investment scams and identity theft. Their closure has disrupted a vital segment of the underground digital economy.

Huione Guarantee had recently undergone a rebranding as “Haowang Guarantee” before its termination. It confirmed on its official website that it had been blocked by Telegram and announced the cessation of its operations.

Connections to the North Korean Lazarus Group

Huione Guarantee is a division of the Cambodia-based Huione Group, which also runs Huione Pay and Huione Crypto. These organizations have drawn attention from international law enforcement. In 2023, Huione Pay was linked to a cryptocurrency wallet tied to the notorious North Korean Lazarus Group, a state-sponsored hacking entity responsible for some of the globe’s most remarkable cyberattacks.

This discovery, along with subsequent financial connections, resulted in the United States government placing the entire Huione Group on a sanctions list, restricting its access to the U.S. financial system. Treasury Secretary Scott Bessent referred to the group as “the preferred marketplace for malicious cyber actors.”

Global Consequences and Australia’s Cybersecurity Scenario

Australia, similar to many other countries, is increasingly influenced by international cybercrime organizations. The dismantling of Xinbi and Huione could assist in decreasing the number of scams and fraudulent investment operations aimed at Australians. In 2023 alone, Australians fell victim to over $3 billion in scams, according to Scamwatch. Eliminating communication pathways utilized by scammers may help mitigate this escalating problem.

Cybersecurity professionals in Australia have praised Telegram’s actions but caution that more measures need to be implemented. Criminal enterprises are highly adaptable, and new avenues may appear to replace those that have been dismantled.

Conclusion

Telegram’s action against Xinbi Guarantee and Huione Guarantee has delivered a severe setback to the cybercriminal ecosystem. These platforms had handled over AU$54.6 billion in illegal transactions, facilitated scams, and supposedly supported operations linked to North Korean hackers. With mounting pressure from international regulators and escalating public scrutiny, technology companies are intensifying their enforcement against illicit activities on their platforms. Nonetheless, the battle against cybercrime is ongoing, and ongoing vigilance will be crucial to safeguarding users and financial systems around the world.

Q: What were Xinbi Guarantee and Huione Guarantee?

A:

These were Chinese-language black market services operating on Telegram. They acted as escrow services for cybercriminals, providing money laundering, stolen data trading, and various illicit fintech services.

Q: Why did Telegram dismantle these platforms?

A:

Telegram pointed to violations of its service terms, especially regarding criminal activities such as scams and money laundering. The platforms were taken down upon discovery.

Q: How much money flowed through these markets?

A:

Blockchain analytics firm Elliptic estimated that Xinbi and Huione processed over US$35 billion (AU$54.6 billion) in illegal transactions since 2021.

Q: What is the Huione Group?

A:

Huione Group is a conglomerate based in Cambodia behind Huione Guarantee. It also oversees Huione Pay and Huione Crypto and has been linked to the North Korean Lazarus hacking group, resulting in U.S. sanctions.

Q: What are the repercussions for Australia?

A:

Australians are common targets for online scams. Disrupting these global black markets may lessen financial losses and shield consumers from fraud originating from overseas.

Q: Is this the end of such black markets on Telegram?

A:

Not necessarily. While this disruption is substantial, cybercriminals can regroup and identify alternative platforms. Continuous oversight and enforcement are critical.

Q: How can users safeguard against online scams?

A:

Australians should stay updated on scam strategies, employ two-factor authentication, avoid dubious links, and report any fraudulent actions to Scamwatch or the Australian Cyber Security Centre (ACSC).

Q: What role do messaging platforms play in cybercrime?

A:

Messaging services like Telegram can be exploited by criminals for secure communication, trading illegal goods, and managing scams. However, with proactive moderation and enforcement, platforms can also contribute to the solution.

A standout capability of Compass is its scorecard system, which DPE employs to evaluate the condition of its software components. Scorecards monitor metrics like test coverage, documentation adequacy, and uptime. These insights assist managers in prioritising updates to legacy systems and establishing measurable KPIs for their teams.

Fraser explained, “Scorecards help identify components that require focus. It’s a tool to ensure quality and speed in software delivery.”

Integrations: Establishing a Fully Connected DevOps Pipeline

Although the Compass integrations continue to mature, DPE is advancing. A custom script currently channels unit test results into the platform, and efforts are underway to sync Compass with Jira Service Management for enhanced incident tracking. Furthermore, service-level monitoring data from New Relic will soon be incorporated into health scorecards to monitor compliance and performance.

“We aim to directly connect support desk concerns to components. That will further reduce incident response durations,” Fraser said.

The Albanese government remains dedicated to achieving 82% renewable energy in the grid by 2030 and net-zero emissions by 2050.

Australia rules out nuclear energy after 2025 election results

Labor Secures Authority Amid Energy Policy Clash

The 2025 federal election yielded a definitive result: Prime Minister Anthony Albanese and the Labor Party will remain in power. Central to the campaign was a clear divergence in energy philosophies — one anchored in renewables, the other in nuclear energy.

Labor’s agenda, focused on relief from rising living costs and expanding clean energy, resonated with Australians concerned about expensive and unreliable energy alternatives. Conversely, Opposition Leader Peter Dutton’s nuclear vision failed to persuade a doubtful voter base, confirming nuclear energy as a non-viable option in Australia’s near-term landscape.

The Coalition’s Nuclear Proposal: Too Pricey, Too Late

Dutton’s Vision

Dutton’s initiative sought to rejuvenate Australia’s energy framework by building seven nuclear power facilities across five states. The project included small modular reactors (SMRs) by 2035 and larger plants by 2037, aiming for a cumulative capacity of 14 gigawatts by 2050. The policy promised savings and energy reliability, particularly as coal facilities go offline.

Projected Costs vs. Reality

While the Coalition projected a $331 billion expenditure for the nuclear development — considerably lower than Labor’s $594 billion renewable strategy — critics quickly dismissed the assertion. Independent analysis from CSIRO and AEMO estimated nuclear energy costs ranging from $145 to $238 per megawatt-hour, compared to significantly lower rates for solar and wind.

In contrast, the Coalition’s own projections optimistically claimed costs of $30 per megawatt-hour — a figure many energy economists regarded as unrealistic considering global trends in nuclear expenses.

Legal and Political Challenges

Australia’s federal prohibition on nuclear energy, established in 1998, would necessitate bipartisan consensus to amend — a nearly impossible task given the opposition from Labor, the Greens, and several critical independents. State-level prohibitions persist in Queensland, Victoria, and other regions, complicating any nuclear expansion.

Even leaders within the Liberal Party, like Queensland Premier David Crisafulli and Victoria’s Brad Battin, expressed their disapproval of nuclear power — underscoring its political unpopularity even among Coalition members.

Why the Nuclear Initiative Failed to Captivate Voters

Limited Public Backing

Despite international discussions regarding nuclear energy’s contribution to decarbonisation, Australian public sentiment remains predominantly negative. Polls during the campaign indicated only 35% of Australians supported nuclear energy, a figure that declined further when voters were informed of Dutton’s specific policy details.

Environmental Issues

Dutton’s intention to prolong the operational lives of coal plants while waiting for nuclear reactors to become operational posed significant climate risks. The Climate Change Authority projected that the strategy could result in up to 2 billion tonnes of CO₂ emissions by 2050 — undermining Australia’s net-zero commitment and broader climate obligations.

Campaign Miscalculations

Dutton’s choice to refrain from campaigning in electorates earmarked for nuclear facilities allowed Labor to dominate the narrative. Energy Minister Chris Bowen labeled nuclear the “Voldemort policy” — a term for the policy that cannot be mentioned — capitalizing on its unpopularity. Labor’s portrayal of nuclear as a threat to Medicare and educational financing proved politically effective.

Labor’s Renewable Vision Gains Traction

Advancements Since 2022

The Albanese administration reports that the share of renewables in the national grid has surged by 25% since 2022. In 2024 alone, over 330,000 rooftop solar systems were installed. These milestones served as proof of the viability and scalability of renewable energy options.

Infrastructure and Financial Commitments

Labor’s Clean Energy Future strategy entails substantial investments in wind, solar, battery storage, and pumped hydro projects. Offshore wind initiatives covering 30,000 km² are already in progress. These projects are backed by the CSIRO and AEMO, both of whom champion a renewables-led shift as the most economical pathway forward.

With coal plants set for closure by 2035, the government must ensure sufficient energy storage and transmission networks to uphold grid reliability and affordability for households.

Conclusion

The Australian voters have sent a clear signal: nuclear energy will not be part of the country’s impending future. Labor’s strong emphasis on renewables, financial relief, and climate pledges secured the support of voters cautious of the dangers and expenses associated with nuclear power. For now, Australia will pursue its energy future through solar, wind, and storage solutions—keeping nuclear energy firmly off the table.

Q: What factors contributed to Labor’s victory in the 2025 election?

A:

Labor prevailed thanks to its emphasis on financial relief, investment in renewable energy, and robust leadership from Anthony Albanese. The party effectively positioned itself as the stable and forward-thinking option, while the Coalition’s nuclear energy plan was perceived as risky and costly.

Q: What did the Coalition propose regarding nuclear energy?

A:

The Coalition suggested constructing seven nuclear reactors at the locations of decommissioned coal facilities, aiming for 14 gigawatts of capacity by 2050. This included small modular reactors by 2035 and larger facilities by 2037, at a projected cost of $331 billion.

Q: What led to the failure of the nuclear initiative?

A:

The proposal collapsed due to legal obstacles, high expenses, insufficient public endorsement, environmental risks, and errors in campaigning. Polls indicated limited voter support, with numerous state leaders, including some from the Liberal Party, expressing opposition to the idea.

Q: Is nuclear energy prohibited in Australia?

A:

Yes, nuclear energy is banned at the federal level under regulations established in the 1990s. Most states also enforce their own prohibitions. Overturning these laws would demand widespread political support, which is currently absent.

Q: What are Labor’s energy objectives?

A:

Labor seeks to achieve 82% renewable energy in the grid by 2030 and aim for net-zero emissions by 2050. The strategy encompasses investments in solar, wind, hydro, battery storage, and grid infrastructure to replace retiring coal facilities.

Q: How did the public react to nuclear energy in surveys?

A:

Only about 35% of Australians were in favor of nuclear energy. Support diminished further as voters educated themselves about the Coalition’s plan, particularly concerning costs and timelines.

Q: What economic concerns surround nuclear energy?

A:

Independent analyses have indicated that nuclear energy is considerably more expensive than renewables. Projects in other nations have faced delays and budget overruns, prompting worries about viability and financial risk for taxpayers.
