Tether has suspended its plan to freeze USDT smart contracts on five blockchains after feedback from community members. The stablecoin will remain transferable on these networks, but can no longer be issued or redeemed.
The decision affects Omni Layer, Algorand, EOS, Bitcoin Cash SLP, and Kusama. Omni Layer is most impacted, holding nearly $83 million in USDT. EOS carries around $4.2 million, while the other chains have less than $1 million combined.
Tether said it will focus on blockchains with strong adoption and developer activity, such as Ethereum and Tron, which hold over $150 billion in USDT. BNB Chain, Solana, and Ethereum layer-2 networks also play key roles in the stablecoin market.
The move comes as stablecoins gain fresh momentum following US President Donald Trump’s signing of the GENIUS Act. Analysts expect the law to strengthen dollar-pegged stablecoins globally, with forecasts suggesting the market could reach $2 trillion by 2028.

A hacker exploited Anthropic’s Claude chatbot to automate one of the most extensive AI-driven cybercrime operations yet recorded, targeting at least 17 companies across multiple sectors, the firm revealed.
According to Anthropic’s report, the attacker used Claude Code to identify vulnerable organisations, generate malicious software, and extract sensitive files, including defence data, financial records, and patients’ medical information.
The chatbot then sorted the stolen material, identified leverage for extortion, calculated realistic bitcoin demands, and even drafted ransom notes and extortion emails on behalf of the hacker.
Victims included a defence contractor, a financial institution, and healthcare providers. Extortion demands reportedly ranged from $75,000 to over $500,000, although it remains unclear how much was actually paid.
Anthropic declined to disclose the companies affected but confirmed new safeguards are in place. The firm warned that AI lowers the barrier to entry for sophisticated cybercrime, making such misuse increasingly likely.

People often treat their email address as harmless, just a digital ID for receipts and updates. In reality, it acts as a skeleton key linking behaviour, purchases, and personal data across platforms.
Using the same email everywhere makes tracking easy. Companies may encrypt addresses, but behavioural patterns remain intact. Aliases disrupt this chain by creating unique addresses that forward mail without revealing your true identity.
Each alias becomes a useful tracker. If one is compromised or starts receiving spam, it can simply be disabled, cutting off the problem at its source.
Aliases also reduce the fallout of data breaches. Instead of exposing your main email to countless third-party tools, scripts, and mailing platforms, an alias shields your core digital identity.
Beyond privacy, aliases encourage healthier habits. They force a pause before signing up, add structure through custom rules, and help fragment your identity, thereby lowering the risks associated with any single breach.

TransUnion, a US consumer credit reporting agency, has suffered a data breach, impacting the personal information of nearly 4.5 million Americans. The breach, detected on 30 July 2025, involved unauthorised access to a third-party application used in its US consumer support operations.
Although credit reports and core credit data were not exposed, specific personal details were compromised. TransUnion is offering affected customers free credit monitoring and fraud assistance. The agency highlighted its commitment to robust security measures and ongoing improvements. The incident follows previous breaches in 2022 and 2023, raising concerns about TransUnion’s overall data protection and third-party risks.
The recent TransUnion breach follows several high-profile data incidents involving third-party compromises. In June 2025, banking giant UBS was affected after its procurement provider Chain IQ was attacked.
In July, Allianz Life reported personal data theft from 1.4 million US customers via a third-party cloud-based CRM breach. Australian airline Qantas also disclosed a breach impacting nearly six million customers through a third-party service platform.

The US AI startup has announced an update to its data policy for Claude users, introducing an option to allow conversations and coding sessions to be used for training future AI models.
Anthropic stated that all Claude Free, Pro, and Max users, including those using Claude Code, will be asked to make a decision by September 28, 2025.
According to Anthropic, users who opt in will permit retention of their conversations for up to five years, with the data contributing to improvements in areas such as reasoning, coding, and analysis.
Those who choose not to participate will continue under the current policy, where conversations are deleted within thirty days unless flagged for legal or policy reasons.
The new policy does not extend to enterprise products, including Claude for Work, Claude Gov, Claude for Education, or API access through partners like Amazon Bedrock and Google Cloud Vertex AI. These remain governed by separate contractual agreements.
Anthropic noted that the choice will also apply to new users during sign-up, while existing users will be prompted through notifications to review their privacy settings.
A threat group known as TAG-144 has stepped up cyberattacks on South American government agencies, researchers have warned.
The group, also called Blind Eagle and APT-C-36, has been active since 2018 and is linked to espionage and extortion campaigns. Recent activity shows a sharp rise in cybercrime, spear-phishing, often using spoofed government email accounts to deliver remote access trojans.
Analysts say the group has shifted towards more advanced methods, embedding malware inside image files through steganography. Payloads are then extracted in memory, allowing attackers to evade antivirus software and maintain access to compromised systems.
Colombian government institutions have been hit hardest, with stolen credentials and sensitive data raising concerns over both financial and national security risks. Security experts warn that TAG-144’s evolving tactics blur the line between organised crime and state-backed espionage.

A phishing campaign exploits Microsoft Teams’ external communication features, with attackers posing as IT helpdesk staff to gain access to screen sharing and remote control. The method sidesteps traditional email security controls by using Teams’ default settings.
The attacks exploit Microsoft 365’s default external collaboration feature, which allows unauthenticated users to contact organisations. Axon Team reports attackers create malicious Entra ID tenants with .onmicrosoft.com domains or use compromised accounts to initiate chats.
Although Microsoft issues warnings for suspicious messages, attackers bypass these by initiating external voice calls, which generate no alerts. Once trust is established, they request screen sharing, enabling them to monitor victims’ activity and guide them toward malicious actions.
The highest risk arises where organisations enable external remote-control options, giving attackers potential full access to workstations directly through Teams. However, this eliminates the need for traditional remote tools like QuickAssist or AnyDesk, creating a severe security exposure.
Defenders are advised to monitor Microsoft 365 audit logs for markers such as ChatCreated, MessageSent, and UserAccepted events, as well as TeamsImpersonationDetected alerts. Restricting external communication and strengthening user awareness remain key to mitigating this threat.

China’s Salt Typhoon cyberspies have stolen data from millions of Americans through a years-long intrusion into telecommunications networks, according to senior FBI officials. The campaign represents one of the most significant espionage breaches uncovered in the United States.
The Beijing-backed operation began in 2019 and remained hidden until last year. Authorities say at least 80 countries were affected, far beyond the nine American telcos initially identified, with around 200 US organisations compromised.
Targets included Verizon, AT&T, and over 100 current and former administration officials. Officials say the intrusions enabled Chinese operatives to geolocate mobile users, monitor internet traffic, and sometimes record phone calls.
Three Chinese firms, Sichuan Juxinhe, Beijing Huanyu Tianqiong, and Sichuan Zhixin Ruijie, have been tied to Salt Typhoon. US officials say they support China’s security services and military.
The FBI warns that the scale of indiscriminate targeting falls outside traditional espionage norms. Officials stress the need for stronger cybersecurity measures as China, Russia, Iran, and North Korea continue to advance their cyber operations against critical infrastructure and private networks.

Russia has been pushing for its state-backed messenger Max to be pre-installed on all smartphones sold in the country since September 2025. Chinese and South Korean manufacturers, including Samsung and Xiaomi, are reportedly preparing to comply, though official confirmation is still pending.
The Max platform, developed by VK (formerly Vkontakte), offers messaging, audio and video calls, file transfers, and payments. It is set to replace VK Messenger on the mandatory app list, signalling a shift away from foreign apps like Telegram and WhatsApp.
Integration may occur via software updates or prompts when inserting a Russian SIM card.
Concerns have arisen over potential surveillance, as Max collects sensitive personal data backed by the Russian government. Critics fear the platform may monitor users, reflecting Moscow’s push to control encrypted communications.
The rollout reflects Russia’s broader push for digital sovereignty. While companies navigate compliance, the move highlights the increasing tension between state-backed applications and widely used foreign messaging services in Russia.
