Australian authorities have arrested and charged two young men accused of being part of the TeamPCP hacking group linked to a string of far-reaching developer supply chain attacks. TeamPCP is a hacking group known for widespread supply-chain attacks over the past year that targeted open-source software and developer platforms to steal credentials, authentication secrets, and source code. High-profile attacks attributed to TeamPCP have impacted Trivy, LiteLLM, Telnyx, SAP, and TanStack packages, while the group has also breached the European Commission, Mistral AI, OpenAI, and GitHub. To carry out their attacks, the threat actors injected malicious code into software hosted on open-source repositories, which developers then unknowingly incorporated into their own applications on systems used by government, academic, and private-sector organizations.
Microsoft has started rolling out a permanent fix for a known issue that causes system crashes and gaming issues on Windows 11 devices. On affected PCs, users have also reported games failing to launch and freezing with "EXCEPTION_ACCESS_VIOLATION" errors. When it was first confirmed, Microsoft said that this issue affects games like ARC Raiders, MARVEL Tōkon: Fighting Souls, and The Finals on systems running Windows 11 24H2 and 25H2. While it was initially believed that the August 2026 updates may be behind these problems, Microsoft later blamed them on peripherals with built-in RGB lighting. "Ongoing investigation indicates that this issue is related to peripherals or internal device components which have RGB lighting features," Microsoft noted. "Such devices may install drivers or code components with file names similar to inpoutx64. In systems where these drivers are found, the issue is then triggered by launching certain games."
The ShinyHunters extortion group has published sensitive data from nearly 13 million accounts stolen from clothing retailer giant Carhartt earlier this month, according to data breach notification service Have I Been Pwned. Founded in 1889, Carhartt is an American apparel company with workwear and streetwear manufacturing facilities in Kentucky and Tennessee and more than 3,000 employees in the United States and Europe. While Carhartt has yet to confirm the extortion group's claims or issue a statement about the breach, ShinyHunters claimed the attack on August 13 and said they allegedly stole more than 50GB of documents containing a wide range of customer, employee, and corporate data. "Millions of records of customer data and vast amount of sensitive information and PII containing employee, customer, customer metadata (royalty info), and other internal corporate data was compromised," the cybercrime gang said.
All threats In Q2 2026, the percentage of ICS computers on which malicious objects were blocked continued to decrease, falling to 19.15%, its lowest level since 2022. Percentage of ICS computers on which malicious objects were blocked, Q3 2023–Q2 2026 Regionally, the percentages ranged from 8.1% in Northern Europe to 27.9% in Africa. Regions ranked by percentage of attacked ICS computers The figures increased in five regions over the quarter, most notably in East Asia (by 2.0 pp) and Africa (by 0.5 pp). East Asia saw increases in percentages for all threats except miners. The region ranked first in terms of growth for malicious scripts and phishing pages, spyware, and viruses. East Asia also led in terms of growth in threats from the internet. The percentage of ICS computers on which email threats were blocked also increased. Selected industries The biometrics sector (26.44%) has traditionally led the rankings of industries and OT infrastructures surveyed in this report in terms of the percentage of ICS computers on which malicious objects were blocked. Biometric systems are characterized by the availability of internet access, extensive email use for data exchange and approvals (e.g. access granting), and, in many cases, minimal cybersecurity controls within the organizations that use them. Industries ranked by percentage of ICS computers on which malicious objects were blocked The biometrics sector ranked first among industries in terms of the following threat categories: malicious scripts and phishing pages, malicious documents, spyware, ransomware, and worms. The sector is also leading among industries in terms of email threats. At the same time, unlike other industries, the percentage of affected ICS computers for email threats in biometrics exceeds that for internet threats. In all selected industries, the global average follows a downward trend. Threat categories In Q2 2026, Kaspersky security solutions blocked malware from 10,904 different malware families of various categories on industrial automation systems. Over the quarter, the percentage of ICS computers on which malicious objects of the following categories were blocked increased: denylisted internet resources, malicious documents, worms, ransomware, and malware for AutoCAD. Percentage of ICS computers on which the activity of malicious objects from various categories was blocked Malicious scripts and phishing pages (JS and HTML) Malicious scripts and phishing pages remained in first place in the threat category rankings based on the percentage of ICS computers on which the respective threats were blocked. In Q2 2026, the global average dropped to 5.42%. Over the quarter, the figure for this category only increased in East Asia, rising by 0.93 pp to 4.86%. This is the second-highest figure in the region in the last three years. In East Asia, the percentage of ICS computers affected by malicious scripts and phishing pages increased in all the industries surveyed, except construction. The highest figures were recorded for biometrics (9.01%) and building automation (6.49%). Denylisted internet resources In Q2 2026, denylisted internet resources rose in the threat category rankings from third to second place, displacing spyware. Globally, the percentage of ICS computers on which denylisted internet resources were blocked has been increasing for two quarters in row and reached 4.31%. The figures increased in all regions over the quarter, most notably in Russia (by 1.33 pp). Moreover, Russia ranked first (5.17%) among the regions in terms of denylisted internet resources. Since 2022, the region has topped these rankings twice before, both times in Q2: in 2022 and 2024. Among the selected industries in Russia, the highest figures for the denylisted internet resources were in the electric power (6.61%) and engineering and ICS integration (5.62%) industries. Malicious documents (MSOffice + PDF) Malicious documents ranked fourth in the threat category rankings by the percentage of ICS computers on which they were blocked. The percentage for this category decreased over the previous three quarters, reaching its lowest level in three years. However, in Q2 2026, it increased to 1.77%. Over the quarter, the figures for malicious documents increased in seven regions, most notably in South America (by 1.35 pp) and Southern Europe (by 0.48 pp). These two regions are among the top three in terms of malicious documents, malicious scripts and phishing pages, as well as threats from email clients. South America ranked second in the rankings of regions in terms of malicious documents. In Q2 2026, the percentage of ICS computers in the region on which this threat was blocked was 3.56%, which was the fourth highest in three years. Among the selected industries in South America, the highest percentage of ICS computers on which malicious documents were blocked was in biometrics (6.67%). Southern Europe ranked first in the rankings of regions in terms of malicious documents. In the previous quarter, the percentage of ICS computers in the region on which this threat was blocked was the lowest in three years, but in Q2 2026 it increased to 3.63%. Among the selected industries in Southern Europe, the highest percentage of ICS computers on which malicious documents were blocked was once again in biometrics (11.48%). Spyware Spyware ranked third in the threat category rankings based on the percentage of ICS computers on which it was blocked. The percentage for this category (3.30%) is the lowest since 2022. Over the quarter, the figures increased in three regions, most notably in East Asia (by 0.53 pp) and Southeast Asia (by 0.42 pp). East Asia ranked third based on the figures for spyware (4.77%), behind Africa and Southeast Asia. This is the region’s highest rate since Q2 2025. Among the countries and territories in the region, the highest percentage of ICS computers on which spyware was blocked was in mainland China (6.61%). Among the selected industries in East Asia, the highest figures for spyware were in the electric power (11.75%) and manufacturing (5.87%) industries. In all the industries surveyed, the figures are higher than the regional average. Southeast Asia ranked second after Africa in the ranking of regions in terms of spyware, with 5.32%. Among the selected industries in Southeast Asia, the highest figures for spyware were in biometrics (8.93%) and manufacturing (7.32%). The figures increased in all industries over the quarter. Ransomware The percentage of ICS computers on which ransomware was blocked decreased in the previous three quarters but increased to 0.16% in Q2 2026. During the quarter, the percentage increased in all regions, except Western and Southern Europe and North America (Canada). Africa led the ranking in terms of growth for this metric. In Q2 2026, Africa ranked first among the regions in terms of the percentage of ICS computers on which ransomware was blocked (0.29%). The only time the figure in the region was higher in the past three years was Q2 2025 (0.31%). Among the selected industries in Africa, the highest figures for ransomware were in the electric power industry (0.72%) and biometrics (0.52%). Over the quarter, the figures increased in all industries, except manufacturing and construction. The biggest increase was recorded in the electric power industry. In Russia, the percentage of ICS computers on which ransomware was blocked in biometric systems has increased for three consecutive quarters, reaching 1.22%. This is the highest level of ransomware across all industries in all regions. Miners In Q2 2026, the percentage of ICS computers on which miners were blocked was the lowest since 2021, for both miners in the form of executable files for Windows (0.48%) and web miners running in browsers (0.14%). The figures for both categories decreased in all regions, except for Africa where figures for miners in the form of executable files for Windows increased slightly. On average, the oil and gas industry led the rankings among the selected industries both in terms of miners in the form of executable files for the Windows OS (0.66%) and in terms of web miners (0.34%). Worms In Q2 2026, the percentage of ICS computers on which worms were blocked increased to 1.43%. In Q2 2026, the Middle East (2.11%) was second (after Africa) in the rankings of regions in terms of worms, displacing Central Asia and the South Caucasus. Among the selected industries in the Middle East, the highest percentage of ICS computers on which worms were blocked was in building automation (2.90%). Over the quarter, the figures increased in all industries. Australia and New Zealand ranked 12th among the regions in terms of the percentage of ICS computers on which worms were blocked (0.41%). Over the past three years, the figure in this region was only higher in Q2 2024 (0.42%). The figures increased in all the surveyed industries in the region, most notably in manufacturing and electric power. As a result, for these industries they exceeded the regional average by 2.9 and 2.3 times, respectively. Viruses In Q2 2026, the percentage of ICS computers on which viruses were blocked decreased to 1.29%. The top three regions for this metric remain unchanged: Southeast Asia (6.03%), Africa (4.22%), and East Asia (3.14%). These same regions lead the rankings in terms of malware for AutoCAD. The figures increased in three regions: East Asia, Australia and New Zealand, and Africa, where it has been growing for four consecutive quarters and reached its highest value since 2022. Among the selected industries in Africa, the highest percentage of ICS computers on which viruses were blocked was in construction (5.47%). East Asia ranked third among the regions in terms of viruses, reaching the highest level in the region for the past three years. Among the countries and administrative regions of East Asia, mainland China is the clear leader in terms of viruses (5.07%). Among the selected industries in East Asia, the highest percentage of ICS computers on which viruses were blocked was in construction (5.93%). In Australia and New Zealand, the increase in the percentage of ICS computers on which viruses were blocked was primarily due to a 4.3-fold increase in the figure for the electric power industry: from 0.29% to 1.24%. For a region where the percentage of attacked ICS computers for all threats is 0.12%, this is a very high value. Malware for AutoCAD In Q2 2026, the percentage of ICS computers on which malware for AutoCAD was blocked increased to 0.31%. The most notable increase over the quarter was observed in Africa. After more than doubling in the previous quarter, the figure for the region continued to rise (although not so dramatically), reaching 1.02%. Among the selected industries across all regions, the highest percentage of ICS computers on which malware for AutoCAD was blocked was in construction in East Asia (6.38%) and in Southeast Asia (4.05%). Main threat sources In Q2 2026, of all the threat sources, the percentage increased only for email. Percentage of ICS computers on which malicious objects from various sources were blocked Internet The percentage of ICS computers on which threats from the internet were blocked decreased to 7.61%, reaching its lowest level since 2021. Over the quarter, the percentage increased in three regions: East Asia by 0.8 pp (to 6.3%), South Asia by 0.3 pp (to 10.4%), and Russia by 0.3 pp (to 6.4%). Among the selected industries across all regions, the highest percentage of ICS computers on which threats from the internet were blocked was in biometrics (13.03%) and engineering and ICS integration (12.16%) in South Asia. Email The percentage of ICS computers on which email threats were blocked increased to 2.84%. In Q2 2026, the percentage of ICS computers on which email threats were blocked increased in South America by 1.0 pp (to 5.2%) and in Africa by 0.7 pp (to 4.3%). Among the selected industries across all regions, the highest percentage of ICS computers on which email threats were blocked was in biometrics (19.14%) and building automation (12.49%) in Southern Europe. Removable media The percentage of ICS computers on which threats from removable media were blocked continued to decrease, reaching 0.24%, the lowest value for the period under review. Among the selected industries across all regions, the highest percentage of ICS computers on which threats from removable media were blocked was in the electric power industry in East Asia (1.34%) and biometrics in Africa (1.29%). Network folders The percentage of ICS computers on which threats from network folders were blocked continued to decrease. In Q2 2026, it was the lowest for the period under review, at 0.023%. The only region to see an increase in the percentage of ICS computers on which threats from network folders were blocked during the quarter was Africa. This was mainly due to an increase in the building automation figure to 0.05%. Among the selected industries across all regions, the highest percentage of ICS computers on which threats from network folders were blocked was in biometrics (0.23%), building automation (0.17%), and engineering and ICS integration (0.13%) in East Asia.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has ordered government agencies to patch their Citrix NetScaler appliances against an actively exploited vulnerability by Saturday. Tracked as CVE-2026-8452, this high-severity security flaw stems from a memory overflow weakness affecting NetScaler ADC and NetScaler Gateway appliances configured with Gateway VPN or AAA (Authentication, Authorization, and Auditing) virtual servers. While Citrix said in June that threat actors could only exploit the flaw in denial-of-service (DoS) attacks, cybersecurity firm watchTowr showed in August that successful exploitation can also allow attackers to gain remote code execution as root on unpatched NetScaler instances. "This is a memory overflow vulnerability that may lead to unpredictable behavior or denial of service and impacts NetScaler Gateway or AAA virtual server," Citrix said at the time. "We have not observed any unmitigated exploitation of this vulnerability as well."
CISA urges water utilities to find and secure internet-exposed PLCs after July attacks showed how easily exposed industrial systems can be compromised. Over 100 internet-exposed systems in the US water and wastewater sector got hit by cyberattacks in July 2026, and CISA’s response wasn’t just an incident report, it was a how-to guide for making sure it doesn’t happen to you next. The agency’s exposure reduction guidance, published August 21, walks through exactly how organizations can find their own internet-facing weak points before an attacker does. The pattern behind the July attacks was surprisingly simple. Most of the affected systems were programmable logic controllers (PLCs), small industrial computers that control pumps and valves. Many connected directly to cellular modems and had no firewall or gateway between them and the internet. CISA warns that this type of setup can expose PLCs to serious security risks. “Directly connecting PLCs to the internet through cellular modems can create significant security risks. However, internet exposure reduction does not mean disabling necessary remote access; organizations should remove remote access when it is unnecessary and secure it when it is necessary.” states CISA. Hackers remotely accessed exposed PLCs, changed device IP addresses and passwords, and in some cases disabled shutdown processes and alarms, creating what CISA called unsafe conditions without notifying the operators running the actual equipment. Iran is the suspected actor behind much of this activity, likely tied to the ongoing war involving the US and Israel, though officials have stopped short of a formal attribution. CISA presents reconnaissance as an ongoing process. Organizations need to know which systems they expose to the internet and can use tools such as Shodan, Censys, or CISA’s Cyber Hygiene Vulnerability Scanning service to check their own IP ranges from the outside. The review should also cover ports used by industrial systems. Besides SSH, RDP, and HTTP, CISA highlights protocols such as Modbus, EtherNet/IP, DNP3, BACnet, and OPC UA. Finding one of these ports open does not automatically mean the system has been compromised, but it does indicate an exposure that needs to be investigated and addressed quickly. Where remote access is genuinely necessary, CISA’s advice is to route everything through a secure, centrally managed gateway rather than connecting straight to a PLC, HMI, or remote terminal unit. Pair that with phishing-resistant multi-factor authentication, unique credentials instead of shared defaults, and active monitoring of traffic in and out, and you’ve closed most of the gap that let this particular wave of attacks succeed in the first place. None of this is exotic security engineering; it’s the same basic hygiene that’s been recommended for years, just finally getting attention because attackers are actually using the gap. This isn’t an isolated incident CISA is responding to reactively, either. The water sector attacks sit inside a much larger pattern of nation-state interest in US and allied critical infrastructure, from China’s Volt Typhoon reportedly pre-positioning malware inside American infrastructure as a potential wartime disruption tool, to Russian-linked campaigns testing water and energy systems across Europe as part of broader pressure on NATO. If a foreign government is willing to spend years quietly waiting inside a power grid, an exposed PLC with a factory-default password isn’t a minor oversight, it’s an open invitation. “CISA urges all critical infrastructure organizations to route all necessary remote access through a secure gateway, firewall, VPN, or other centrally managed access solution, rather than connecting directly to a PLC, human-machine interface (HMI), or remote terminal unit (RTU).” concludes CISA. “The July 2026 malicious cyber activity targeting WWS Sector entities demonstrates the consequences of directly exposing PLCs to the internet. Threat actors remotely accessed internet-exposed PLCs, changed device IP addresses and passwords, and caused loss of monitoring and control functionality and, in some cases, operational disruptions.” If you run anything with the letters PLC, SCADA, ICS, or HMI in its job description, this guidance isn’t optional reading for next quarter. Go run the scan today, because the alternative is finding out the hard way that someone else already ran it for you.
