"SideCopy campaign operations typically initiate through spear-phishing campaigns that leverage the abuse of mshta.exe to execute malicious scripts and circumvent standard security protocols," Trellix researchers
Cybersecurity researchers have flagged a new Android malware called RatHat that's assessed to be operated by China-based threat actors and features an artificial intelligence (AI)-powered system to navigate and control compromised devices. "Distributed primarily via targeted smishing (SMS/text phishing) and malvertising campaigns leading to deceptive third-party download portals, RatHat uses
Microsoft has disclosed details of two campaigns in which threat actors are abusing third-party email delivery infrastructure to blast financial fraud scam messages and using passkey-themed social engineering to breach cloud environments. The first campaign, per the tech giant, involved sending over a million scam emails between August 3 and 5, 2026, by masquerading as chief executive officers
Trezor has revealed that phishing attacks against its customers earlier this week targeted 347,000 email addresses and affected 2,500 users who clicked an embedded malicious link. As Trezor warned on Wednesday, threat actors who breached Brevo, its third-party email provider, were emailing customers who opted in to receive newsletters. According to customers targeted in this phishing campaign, they received fake "critical security alert" emails from help@trezor.io claiming that a "hardware microcontroller vulnerability" in Trezor cold storage wallets' STM32 microcontrollers could expose their seeds to brute-force cracking. The phishing emails tried to trick recipients into clicking a malicious link that prompted them to download an app that asked them to enter their wallet backup. Trezor says that it took down the domain used in the phishing attacks within 20 minutes, disabling the link and limiting the campaign's impact to 2,500 customers who had clicked it before it was taken down.
Cryptocurrency hardware wallet maker Trezor warned customers on Wednesday that threat actors who breached its third-party email provider are targeting them in phishing attacks. Affected customers received fake "critical security alert" emails from help@trezor.io claiming that a "hardware microcontroller vulnerability" in the STM32 microcontrollers used by Trezor cold storage wallets could expose their seeds to brute-force cracking. The company said that it's investigating the breach and that the domain has been taken down to stop the attacks. "Our third-party e-mail provider has been breached. Please be aware that the email named 'Critical Security Alert: STM32 Entropy Vulnerability' is not coming from us, and it's a phishing attempt. Do not click on any link," Trezor warned. "We have taken down the domain, and we are investigating the situation, including how the hackers got access to our legit domain."
Microsoft is alerting of a "high-volume phishing campaign" that's using invisible Unicode tag characters to bypass email filters. "Instead of using these characters to hide instructions from people while exposing them to AI models, the attacker used them to split financial lure words such as 'funding' to prevent email filters from parsing them," the Microsoft Security Research team said. The
The worst part is how normal these attacks look. A call from IT. A shared file. A trusted app. A simple request to click “Allow.” Why break in when someone might open the door? That idea runs through this edition. Attackers use real tools, fake login pages, old account links, and software guides that point to unsafe downloads. One wrong letter in a web address can be enough. There is also
An RMM phishing campaign initially associated with Canadian targeting due to its use of Canada Revenue Agency (CRA) tax forms as lures has turned out to be part of a broader campaign spanning 46 countries. Around 45% of observed activity was associated with the United States, making it the campaign's top geographic target. ANY.RUN research connected 601 cases to the wider operation, which uses
Trump targets foreign-made power grid equipment, citing cyber, sabotage and supply-chain risks to U.S. national security. Executive Order 14420, signed on August 26, targets equipment and technologies that could expose the power grid to sabotage, unauthorized access, malicious remote activity or supply-chain disruption. The timing matters. The White House points to the rapid expansion of data centers, artificial intelligence, advanced manufacturing and defense production as reasons why the United States now depends even more heavily on reliable electricity. A disruption that might once have been treated primarily as an energy problem can now affect defense operations, critical infrastructure, emergency services and large parts of the economy. The order frames the problem in two ways. Foreign-made equipment can introduce a direct cybersecurity risk, including the possibility of hidden digital access mechanisms, while dependence on overseas suppliers can create a second vulnerability if geopolitical tensions or trade disruptions suddenly cut off critical components. The White House’s language is unusually broad when describing the scope of the concern. “NOW, THEREFORE, I, DONALD J. TRUMP, President of the United States of America, find that the situation with respect to the foreign supply of bulk-power system electric equipment constitutes an unusual and extraordinary threat, which has its source in whole or substantial part outside the United States, to the national security, foreign policy, and economy of the United States and hereby declare a national emergency with respect to that threat.” reads the Executive Order 14420. “This threat exists both in the case of individual transactions and when transactions are considered as a class. To deal with this threat, additional steps are required to protect the security, integrity, and reliability of bulk-power system electric equipment used in the United States.” That definition matters because the order isn’t aimed only at a specific piece of hardware from a specific country. It creates a framework under which the Energy Secretary can determine whether particular foreign entities, suppliers, countries or equipment present an unacceptable risk and then restrict transactions involving them. The restrictions apply to the acquisition, importation, transfer or installation of foreign-produced bulk-power equipment when the relevant transaction involves a designated Covered Foreign Entity and meets one of the risk conditions set out in the order. Those conditions include the possibility of sabotage, subversion, unauthorized access, malicious remote action or disruption of the power system and its supply chain. The order also reaches beyond the physical equipment itself. Its scope includes critical components, software, firmware, digital services, maintenance services and remote-access capabilities associated with covered equipment. “the transaction involves bulk-power system electric equipment — or any critical component, software, firmware, digital service, maintenance service, or remote-access capability associated with such equipment — designed, developed, manufactured, or supplied by persons owned by, controlled by, or subject to the jurisdiction or direction of a Covered Foreign Entity; and” continues the order. In practical terms, the government isn’t treating a transformer, an industrial controller and the software that manages it as completely separate security questions. That is particularly relevant to industrial control systems. The definition of covered equipment includes remote terminal units, programmable logic controllers, intelligent electronic devices, distributed control systems and safety instrumented systems, alongside transformers, generators, inverters, battery storage systems, protective relays, metering equipment and high-voltage circuit breakers. The order also allows agencies to consider software, firmware, remote access, update mechanisms and other supply-chain dependencies when deciding whether equipment falls within its security concerns. The geographical scope is also worth noting. The order defines the bulk-power system around interconnected transmission infrastructure and generation resources needed for grid reliability, including transmission lines rated at 69 kV or higher. Local electricity distribution facilities fall outside that definition. This isn’t only about equipment that companies might buy tomorrow. The Energy Secretary can also impose conditions on foreign-manufactured or foreign-operated equipment already installed before the order took effect. Depending on the risk, those measures could require operators to identify, isolate, monitor, secure, disconnect, replace or remove equipment. The order specifically requires officials to consider reliability, safety, the availability of secure replacements and continuity of essential services before demanding isolation or replacement. That last point is important because securing a power grid isn’t as simple as unplugging a suspicious device. Removing a component without a suitable replacement can itself create an operational problem. The order therefore leaves room for phased compliance and negotiated mitigation measures rather than assuming that every risky component can disappear overnight. The government also wants to avoid turning security screening into a permanent procurement bottleneck. The Energy Secretary can establish criteria for pre-qualified equipment and vendors, creating a list of products and suppliers that can receive exemptions from the baseline restrictions. At the same time, the order makes clear that pre-qualification doesn’t prevent the government from scrutinizing or restricting a transaction later if circumstances warrant it. The order doesn’t name a specific country as the target. Instead, it defines a Covered Foreign Entity broadly enough to include governments under certain U.S. arms embargoes or sanctions regimes, as well as entities that the relevant U.S. authorities determine are engaged in conduct detrimental to national security or foreign policy. SecurityWeek also noted that the structure resembles earlier Trump-era restrictions on foreign bulk-power equipment, including measures that previously focused on entities associated with China. The order does not mention any country by name. However, its structure is very similar to a 2020 Trump-era order on the U.S. power grid, which later led the Department of Energy to ban companies linked to China. The next phase will be regulatory rather than rhetorical. Within 120 days, the Energy Secretary is expected to issue rules or regulations needed to implement the order, including procedures for identifying covered entities, equipment and countries and for licensing transactions that would otherwise be prohibited. The administration also wants recommendations for changes to federal procurement rules that would give greater weight to national security risks and favor U.S.-manufactured energy infrastructure. Those procurement changes have their own timetable. The Energy Secretary has 180 days to develop recommendations for revisions to the Federal Acquisition Regulation, while the FAR Council would then have 90 days to consider proposing corresponding amendments for public comment. The policy fits into a wider push by the administration to reduce dependence on foreign supply chains for strategically important infrastructure. The Department of Energy said earlier this month that it is working to increase domestic production and availability of critical grid components, pointing to rapid growth in electricity demand and the need to strengthen the grid supply chain. For cybersecurity professionals, however, the most interesting part of the order isn’t the preference for domestic manufacturing. It’s the decision to treat supply-chain exposure, remote access and embedded technology as part of the attack surface of the power grid. That changes the question organizations need to ask about critical equipment. It’s no longer enough to know whether a device has a vulnerability today; operators also need to understand who made it, who controls the supplier, where critical software and firmware come from, who can remotely access the equipment, how updates reach it and what happens if that supply chain suddenly becomes unavailable. The uncomfortable reality is that a power grid compromise doesn’t necessarily begin with someone breaking through the perimeter of a utility network. It can begin much earlier, when an organization buys a component it can’t fully inspect, relies on a remote maintenance channel it doesn’t control, or becomes dependent on a supplier it can’t replace quickly. That’s the security problem Executive Order 14420 is trying to address. The White House has effectively moved part of the grid’s cyber defense line back into procurement, manufacturing and supply-chain decisions. And for critical infrastructure operators, that’s a much harder problem to solve than simply finding another firewall.
