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."
Meta will pay up to $18B and cap teen Facebook and Instagram use at two hours daily after nearly all US states sued over child safety. Meta will pay up to $18 billion over the next decade and impose real usage limits on teenagers using Facebook and Instagram, settling claims that the company deliberately designed its platforms to addict children. The deal ended a federal trial mid-stream, right as Instagram head Adam Mosseri had begun testifying and Mark Zuckerberg was expected to take the stand next. The timing made sense given the huge potential penalties. Four states, California, Colorado, Kentucky, and New Jersey, were seeking up to $200 billion in damages. Before the trial, Meta said they could demand as much as $1.4 trillion. Against those figures, the $18 billion settlement looks relatively small, although it still equals about three to four months of Meta’s profits. The most important part of the deal is what Meta agreed to change. Teenagers will be limited to two hours a day on Facebook and Instagram. Meta will also block access between midnight and 6 a.m. unless a parent gives permission, and it will turn off most push notifications during school hours. “The focus of this case was to protect our kids,” Colorado Attorney General Phil Weiser said in a statement reported by Reuters. “The relief we are getting in this settlement is very meaningful and well beyond what any court has ordered or is likely to order.”” What the settlement leaves unchanged matters too. Meta does not have to stop using personalized recommendations or targeted ads for teenagers. It also does not have to remove specific types of content that researchers have linked to negative effects, such as posts that can make users feel worse about their bodies. A two-hour limit is still a meaningful restriction, but Meta can continue trying to maximize engagement during those two hours. The deal also creates an interesting financial incentive. Of the roughly $16.7 billion going to 47 states, Washington D.C., Puerto Rico and other territories, about $12.7 billion is guaranteed. The remaining $5 billion depends on whether Snapchat, TikTok and YouTube introduce similar protections for teenagers. This gives Meta a financial reason to push its competitors to adopt the same rules, which is why the company reportedly plans to use newspaper ads to encourage TikTok and YouTube to follow suit. Separately, Wednesday’s settlement also resolved lingering state privacy claims tied to the Cambridge Analytica scandal, with Meta agreeing to pay $459 million on top of everything else. That’s an old wound getting stitched up alongside a much newer one, in the same afternoon. Not every state joined the settlement. New Mexico stayed out after winning a $567 million public nuisance ruling against Meta earlier this month, on top of a separate $375 million jury verdict. Attorney General Raul Torrez said the settlement didn’t include some changes his case had pushed for, including stronger protection against adults targeting children and a ban on sexualized AI chatbot interactions with minors. Still, he called the deal a step forward. Florida rejected the settlement altogether. Attorney General James Uthmeier said the payouts amount to “peanuts” compared with the harm caused and said Florida would take Meta to trial instead. Legal experts already see the settlement as a possible model for future cases. Northwestern law professor James Speta said Meta and other tech companies faced growing pressure to change anyway, from Congress, state lawmakers and the public. That makes the settlement more than a single case: it could set a standard that courts and regulators use when judging other platforms. Thousands of similar lawsuits from individuals, school districts and municipalities are still moving through courts across the U.S. If those cases follow the same pattern, we haven’t seen the last of these headlines. “Today, we are announcing an agreement with a bipartisan group of 52 attorneys general across US states, territories, and the District of Columbia, building on our longstanding efforts to empower parents and support teens.” reads the statement published by Meta. “Over the years, we have consistently partnered with parents and experts — listening, learning, and building. That’s why we launched Teen Accounts in 2024, to bring automatic protections to teens, and more control for parents.” The agreement aims to push YouTube, TikTok and other platforms to adopt similar protections for teenagers. “While this is an important step, the fact is that teens move fluidly between dozens of apps a day. All platforms should empower parents and support teens by putting the same measures in place, because we know that when teens are restricted on one app, they simply move to another.” concludes Meta. “For meaningful progress to happen, we urge TikTok and YouTube to join us and state attorneys general in adopting this new standard, to ensure teens use social media in a healthy and responsible way.” Follow me on Twitter: @securityaffairs and Facebook and Mastodon Pierluigi Paganini (SecurityAffairs – hacking, Facebook)
ATF, the regulatory agency that enforces federal laws governing firearms and explosives in the United States, has confirmed that one of its systems was compromised after breach claims made by the Qilin ransomware gang. This follows Qilin adding the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives to its dark web data leak portal on Wednesday, without saying whether it had stolen files from ATF's systems or demanded a ransom. The same day, the ATF published a press release saying that a standalone system was breached in what it described as a "major incident," which is now being investigated in collaboration with the Department of Justice. "The impacted system operates separately from the ATF enterprise network, and there is no indication that the incident has affected the ATF enterprise network, the ATF eForms system, or any other ATF system," the federal law enforcement agency said.
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.

A newly disclosed Rowhammer attack called GPUThor can bypass error-correcting code (ECC) protections on NVIDIA GPUs, enabling denial-of-service (DoS) and root-level privilege escalation. In a paper published by the University of Toronto, researchers say that GPUThor achieves far more practical bit-flip rates than past concepts like their own GPUHammer or GPUBreach, which became irrelevant after ECC was introduced. The attack was demonstrated against Ampere-class NVIDIA workstation GPUs with GDDR6 memory, including the RTX A4000, RTX A4500, RTX A5000, and RTX A6000, all widely used in AI and cloud infrastructure. Rowhammer is the name for a class of attacks where memory rows are repeatedly accessed (“hammered”) in a way that increases the likelihood of bits in neighboring memory regions to flip, changing their state from one to zero or vice versa.
Meta has reached a proposed settlement worth up to approximately $18 billion with a bipartisan coalition of 52 attorneys generals over allegations that Facebook and Instagram were deliberately designed to encourage compulsive use by children and teenagers.
Medical technology company Boston Scientific has been targeted in a cyberattack that disrupted some of its IT systems, causing operational disruptions globally. The company detected the incident on August 25 and says in an announcement today that it caused a network outage and "impacted access to certain operating systems and business applications, including the ability to process and ship customer orders." After identifying the intrusion, Boston Scientific activated its incident response procedures and contracted external cybersecurity experts to investigate the impact and help with containment efforts. The company said it does not yet know when all affected systems will be restored. “The incident has caused, and is expected to continue to cause, disruptions and limitations of access to certain of the Company’s information systems and business applications that support aspects of the Company’s operations, including the ability to process and ship customer orders,” Boston Scientific states.
Attackers are now targeting a chain of two Microsoft SharePoint vulnerabilities that can allow them to execute arbitrary code on unpatched servers, according to threat intelligence company Defused. The first (tracked as CVE-2026-55040) is an authentication bypass flaw in the JWT token validation pipeline that attackers without privileges can exploit to perform operations as a SharePoint site user or administrator. The second (CVE-2026-63520) is a vulnerability in SharePoint's Business Connectivity Services (BCS) that unauthenticated attackers can chain after successfully exploiting CVE-2026-55040 for remote code execution (RCE) on a targeted SharePoint Server. Both flaws have publicly available proof-of-concept (PoC) exploits, released by Rapid7 security researcher Stephen Fewer on August 11 (for CVE-2026-55040, representing the first part of the exploit chain) and by VulnCheck vulnerability researcher Jonathan Peterson on August 24 (for CVE-2026-63520).
Snowflake is ending password authentication for legacy service accounts, forcing organizations to migrate them to passwordless methods. Token Security explains why the harder challenge is identifying what uses each account, who owns it, and how much access it still needs.
