About $6.3 billion in cryptocurrency was stolen from Binance in what might be the biggest crypto hack in history. “Binance’s initial investigation suggests that the security incident may involve a compromised DevOps engineer’s laptop, which allowed an attacker to gain access to a service container and submit unauthorized withdrawal transactions,” the exchange said in a security update published early on October 30. The company found no evidence of a wallet private key leak and plans … More →
Attackers posing as IT help desk staff contacted employees by phone, email and Microsoft Teams in the third quarter of 2026 and talked them into opening remote access sessions, Cisco Talos Incident Response (Talos IR) found across several engagements. In one case, that access ended in ransomware. They knew names and email addresses “The attackers appeared to know employee names and email addresses, as they contacted users directly by email and Teams and used identities … More →
A hacker leaks personal data on more than 40,000 DHS employees, including CBP, ICE and CISA staff, after an undisclosed breach.
Personal details of thousands of U.S. Department of Homeland Security (DHS) employees are now online after a hacker stole reams of data in a data breach that occurred earlier this year and nobody had disclosed.
“The breach includes names, job titles, and work contact information, such as email addresses, cell phone numbers, and office locations, of more than 40,000 people who work for the federal department, including border and immigration agents, cybersecurity staffers, and senior department officials.” TechCrunch reports.
The incident impacted border and immigration agents, cybersecurity staff and senior department officials. DHS confirmed it is aware of a potential breach and is investigating, saying it takes threats to employees seriously and will provide updates when more information is available.
“DHS is aware of a potential breach and is actively working to address the situation swiftly and effectively. We take all security threats against our employees and officers seriously and will work to ensure all are properly protected. We will update the public when more information is available,” a DHS spokesperson told SecurityWeek.
The hacker, who uses the name Department of Peace, claims to have stolen the data from an Okta single sign-on system. DHS uses this service to give employees and contractors across its agencies access to the department’s central network. The system also stores IT and login records for each account, showing which systems and internal apps each person can access. The hacker left a note with the leaked data, seen by TechCrunch, saying that if others have their information, it is only fair to share theirs. The malicious actor did not reveal how the U.S. agency was breached.
More than half of the records, around 21,000, belong to U.S. Customs and Border Protection (CBP) employees working at airports and other ports of entry. Another 10,000 belong to Immigration and Customs Enforcement (ICE) and its Homeland Security Investigations unit, while just under 1,000 are linked to the cybersecurity agency CISA. Thousands of other records belong to DHS headquarters and agencies such as U.S. Citizenship and Immigration Services and the Federal Protective Service.
DDoSecrets says the leaked database identifies officials involved in undercover operations and key DHS personnel overseeing renditions and deportations. Department of Peace said the leak was a response to the government’s actions against ICE. Crimew described the database as an unprecedented view of DHS’s organizational structure, helping researchers identify employees, their roles and reporting lines. They said it could also support investigations and future Freedom of Information Act (FOIA) requests.
DDoSecrets co-founder Emma Best said the database, called Icepick, identifies officials involved in covert operations, internal investigations and deportation programs. Ryan Shapiro of Property of the People added that employee contact details could help researchers submit more targeted FOIA requests. Best said the data could also support journalism, congressional inquiries, legal challenges and community investigations.
“Rather than an indiscriminate directory of every DHS employee, Icepick identifies many of the architects and drivers of DHS policy and operations,” said journalist and DDoSecrets cofounder Emma Best. “The leak is extraordinary but deceptive in its simplicity as it identifies the officials responsible for overseeing covert and undercover operations, the government’s hunt for leakers and the failed BlueLeaks investigation — along with key personnel in DHS’s ever-escalating rendition and deportation programs.”
“By replacing the regime’s anonymity with accountability, Icepick and the tool developed by maia are catalyst for investigations, empowering journalists, Congressional inquiries, legal challenges, community action and Freedom of Information Act requests,” added Best.
DHS is investigating a potential breach. Okta says it has no evidence its systems or data were compromised.
The breach follows other attacks on U.S. government agencies that exposed FBI records and military personnel data. It is also the second DHS breach this year, after the same hacker claimed to have stolen thousands of government contracts.
Journalist maia arson crimew shared the data with DDoSecrets. TechCrunch verified some records, which suggest the database was copied around mid-August. The leak covers about one-fifth of DHS’s 220,000 employees.
The records reveal access to tools including Microsoft 365, ChatGPT, Penlink surveillance software and Mobile Fortify, a facial recognition app used by CBP and ICE. Around 4,500 accounts belong to a Headspace user group, while more than 2,000 Homeland Security Investigations employees appear in Penlink-related groups.
Researchers say the contact details could help journalists file targeted Freedom of Information Act requests. However, exposing employees’ phone numbers and office locations also creates security and privacy risks.
Binance probes suspicious crypto transfers worth up to $5.8 billion as Tether and Circle freeze $1.79 billion in stablecoins linked to the activity.
Binance is investigating a potential security incident after billions of dollars in cryptocurrency moved from wallets linked to the exchange on October 29. The transfers raised concerns about a possible hack, while Tether and Circle moved to freeze stablecoins linked to the suspicious activity. The full scope of the incident remains unclear, and the reported outflows shouldn’t automatically be treated as confirmed losses.
According to The Block, blockchain analyst Spreek identified approximately $3.55 billion in incoming transfers to an initially unidentified wallet.
“Onchain data flagged by analyst Spreek shows about $3.55 billion in incoming transfers to the unlabeled wallet, with nearly $900 million subsequently moved across other wallets.” The Block reports. “Conor Grogan, a senior director and product leader at Coinbase, says the amount is up to $5.8 billion.”
Coinbase executive Conor Grogan estimated that the total value of the movements could reach $5.8 billion.
Binance acknowledged the reports and said its security team was investigating. The company had not publicly confirmed a breach in the initial reports, making it important to distinguish between suspicious transactions and a verified compromise.
“We are aware of reports of a potential security issue and we are actively investigating.” He wrote in a post on X. “Our security teams are reviewing all relevant information with urgency, and we will provide updates through official Binance channels as soon as we have verified information. Users should remain cautious of scams and should not trust unofficial links, messages, or requests for account information.”
We are aware of reports of a potential security issue and we are actively investigating. Our security teams are reviewing all relevant information with urgency, and we will provide updates through official Binance channels as soon as we have verified information. Users should…
This statement, reported by The Block, reflects the company’s position at the time. Binance also urged users to be cautious of unofficial messages and links, a relevant warning whenever a major security incident attracts public attention.
Blockchain records showed large transfers from Binance-linked hot wallets to a wallet that wasn’t previously identified as belonging to the exchange. Hot wallets hold cryptocurrency in systems connected to the internet, allowing exchanges to process withdrawals and other transactions quickly. Their online availability also makes their security controls particularly important.
The transfers involved Ethereum, stablecoins and other cryptocurrencies. Some funds were later moved to additional wallets, making it harder to track all the transactions.
Investigators must determine who initiated the transfers, whether they were authorized and whether an attacker gained control of the wallets. They also need to establish whether the funds belonged to customers or Binance itself.
Large transfers alone don’t prove a hack. However, unusual movements involving large amounts of cryptocurrency require immediate investigation.
One of the most significant developments was the response from the companies behind two major stablecoins, USDT and USDC. According to The Block and Forbes, Tether and Circle froze approximately $1.79 billion in stablecoins associated with the suspicious transfers in the initial reports.
The figures subsequently changed as the investigation developed. Tether CEO Paolo Ardoino later said the company had frozen more than $1.567 billion in USDT linked to a potential Binance exchange hack. These amounts reflect reported actions at different points in time and shouldn’t be combined without checking whether they refer to distinct assets and addresses.
Tether froze more than 1.567B USDT related to a potential Binance exchange hack.
Protecting the industry and our partners is our main priority.
The freezes demonstrate an important feature of centralized stablecoins: their issuers can restrict transfers from addresses they control through their token contracts. This can help contain suspected theft, but it doesn’t provide the same control over assets such as Ether or Bitcoin. Nor does freezing a balance guarantee that every transferred asset can be recovered.
The incident also highlights a practical tension in crypto security. Stablecoins offer the convenience of blockchain transfers, but their centralized issuers retain powers that can make a difference during an investigation.
Binance maintained that customer funds were safe, while co-founder Changpeng Zhao, widely known as CZ, said the activity appeared to be a hack. Zhao no longer manages Binance’s platform, but said he expected customers’ funds to be fully covered.
The company said its user funds were “completely safe.”
“Our teams are aware of reports of a potential security issue and are actively investigating. User funds are completely safe. Our security teams are reviewing all relevant information with urgency, and we will provide updates through official Binance channels as soon as we have verified information.” the company states. “Users should remain cautious of scams and should not trust unofficial links, messages, or requests for account information.”
That assurance is important, but it doesn’t replace a technical explanation of how the transfers occurred or independent confirmation of the final impact.
A security investigation must establish more than whether an exchange can cover a potential loss. It should determine how the activity was authorized, whether credentials or signing mechanisms were compromised, which systems were involved and whether the attacker retained any access.
For customers, the immediate priority is to avoid becoming a secondary victim. Attackers often exploit uncertainty around a major incident to distribute fake announcements, impersonate support staff and direct users to fraudulent websites. Users should rely on official Binance communication channels, avoid unexpected links and never disclose passwords, authentication codes or wallet recovery phrases in response to unsolicited messages.
Security teams should also watch for phishing emails that use the incident to demand urgent account verification. Attackers may exploit the situation to launch a separate scam.
The key lesson is that blockchain transparency does not guarantee operational security. Public ledgers show transactions, but they don’t reveal who authorized them, how attackers may have gained access or whether an exchange’s internal security controls failed.
As the investigation continues, it’s important to distinguish between reported transfers, confirmed theft and funds that can be recovered. The figures may change as analysts trace more wallets and stablecoin issuers take further action.
Authorities seized the domain of Virtualine, a bulletproof hosting provider that cybercriminals used to commit a large-scale sextortion scheme, ransomware, data theft, malware hosting and money laundering, the Justice Department said Tuesday.
Virtualine facilitated prolific criminal activity, including the distribution of child sexual abuse material (CSAM), the Justice Department said. The Russian-speaking bulletproof hosting provider was among the most active this year in crypto-related crime in particular, researchers said.
The site and its associated infrastructure stands out among the dozens of bulletproof hosting providers currently tracked by TRM Labs. “It was not among the largest by total inflows, but it received the most illicit-attributed value in 2026 to date,” the blockchain and cryptocrime research firm wrote in a blog post.
Virtualine received almost one-fifth of all illicit-attributed inflow among bulletproof hosting providers tracked by TRM this year to date.
A Russian drug marketplace accounted for nearly 44% of the direct payments Virtualine received from customers and attributed counterparties so far this year, according to TRM. A sextortion scheme accounted for nearly 17% of direct payments to Virtualine, followed by a cryptocurrency mixer at almost 13%, ransomware at nearly 5%, cybercrime services at 3% and malware at 2%.
“Virtualine is another example of Russia’s illicit economy at work: darknet markets, ransomware groups, non-compliant exchanges, and brokers all feeding the same ecosystem,” Ari Redbord, global head of policy at TRM Labs, said in a prepared statement.
“Bulletproof hosting is the connective tissue. Seizing a domain matters, but the blockchain record doesn’t disappear with it. It shows who is paying, who is getting paid, and where they go next,” he added.
Virtualine attracted many criminals as customers. Ransomware groups, including Coinbase Cartel, The Gentlemen, INC, DragonForce and Qilin all paid the site’s operators, according to TRM. The bulletproof hosting provider also received payments from the StealC infostealer, the Matanbuchu loader, bot and malware-distribution services and sites linked to CSAM.
The FBI and prosecutors got a court order to seize Virtualine’s primary domain, which was also known as Secury, Massgod, Spamhouse, Lanedo and Omegatech.
Officials said Virtualine continued hosting services for a customer that distributed CSAM and a hack-for-hire service after it received numerous notices from law enforcement in Germany, Canada, Australia, the National Center for Missing and Exploited Children and a victim’s attorney.
TRM underscores that Virtualine was disrupted, but not completely shut down. “A domain seizure disrupts how customers find and access a service,” researchers wrote. “It does not, by itself, establish that the operator has stopped working, or that customers have lost access to all underlying infrastructure.”
