Apple kicked off its annual Worldwide Developers Conference (WWDC) today with a keynote where the company laid out some of the new features coming to Macs, iPhones, iPads, Apple Watches, and the Apple Vision Pro headset. Leading up to the event, there was a lot of buzz about Apple’s first big foray into the AI […]
Drinking-water systems pose increasingly attractive targets as malicious hacker activity is on the rise globally, according to new warnings from security agencies around the world. According to experts, basic countermeasures—including changing default passwords and using multifactor authentication—can still provide substantial defense. However, in the United States alone, more than 50,000 community water systems also represent a landscape of potential vulnerabilities that have provided a hacker’s playground in recent months.
Yet the larger threat is still very real, according to officials. “When we think about cybersecurity and cyberthreats in the water sector, this is not a hypothetical,” a U.S. Environmental Protection Agency spokesperson said at a press briefing last year. “This is happening right now.” Then, to add to the mix, last month at a public forum in Nashville, FBI director Christopher Wray noted that China’s shadowy Volt Typhoon network (also known as “Vanguard Panda”) had broken into “critical telecommunications, energy, water, and other infrastructure sectors.”

A 2021 review of cybervulnerabilities in water systems, published in the journal Water, highlights the converging factors of increasingly AI-enhanced and Internet-connected tools running more and bigger drinking-water and wastewater systems.
“These recent cyberattacks in Pennsylvania and Texas highlight the growing frequency of cyberthreats to water systems,” says study author Nilufer Tuptuk, a lecturer in security and crime science at University College London. “Over the years, this sense of urgency has increased, due to the introduction of new technologies such as IoT systems and expanded connectivity. These advancements bring their own set of vulnerabilities, and water systems are prime targets for skilled actors, including nation-states.”
According to Katherine DiEmidio Ledesma, head of public policy and government affairs at Washington, D.C.–based cybersecurity firm Dragos, both attacks bored into holes that should have been plugged in the first place. “I think the interesting point, and the first thing to consider here, is that these attacks were not extremely sophisticated,” she says. “They exploited things like default passwords and things like that to gain access.”
Low priority, low-hanging fruit
Peter Hazell is the cyberphysical security manager at Yorkshire Water in Bradford, England—and a coauthor of the Water 2021 cybervulnerability review in water systems. He says the United States’ power grid is relatively well-resourced and hardened against cyberattack, at least when compared to American water systems.
“The structure of the water industry in the United States differs significantly from that of Europe and the United Kingdom, and is often criticized for insufficient investment in basic maintenance, let alone cybersecurity,” Hazell says. “In contrast, the U.S. power sector, following some notable blackouts, has recognized its critical importance...and established [the North American Electric Reliability Corporation] in response. There is no equivalent initiative for safeguarding the water sector in the United States, mainly due to its fragmented nature—typically operated as multiple municipal concerns rather than the large interconnected regional model found elsewhere.”
DiEmidio Ledesma says the problem of abundance is not the United States’ alone, however. “There are so many water utilities across the globe that it’s just a numbers game, I think,” she says. “With the digitalization comes increased risk from adversaries who may be looking to target the water sector through cyber means, because a water facility in Virginia may look very similar now to a water utility in California, to a water utility in Europe, to a water utility in Asia. So because they’re using the same components, they can be targeted through the same means.
“And so we do continue to see utilities in critical infrastructure and water facilities targeted by adversaries,” she adds. “Or at least we continue to hear from governments from the United States, from other governments, that they are being targeted.”
“We developed a white paper recommending this type of approach in 2021,” Morley says. “I have testified to that effect several times, given our recognition that some level of standardization is necessary to provide a common understanding of expectations.”
“I think the best phrase to sum it up is ‘target rich, resource poor.’” —Katherine DiEmidio Ledesma, Dragos
Hazell, of Yorkshire Water, notes that even if the bill does become law, it may not be all its supporters might want. “While the development of the act is encouraging, it feels a little late and limited,” he says. By contrast, Hazell points to the United Kingdom and the European Union’s Network and Information Security Directives in 2016 and 2023, which coordinate cyberdefenses across a range of a member country’s critical infrastructure. The patchwork quilt approach that the United States appears to be going for, he notes, could still leave substantial holes.
“I think the best phrase to sum it up is ‘target rich, resource poor,’” says DiEmidio Ledesma, about the cybersecurity challenges municipal water systems pose today. “It’s a very distributed network of critical infrastructure. [There are] many, many small community water facilities, and [they're] very vital to communities throughout the United States and internationally.”
In response to the emerging threats, Anne Neuberger, U.S. deputy national security advisor for cyber and emerging technologies, issued a public call in March for U.S. states to report on their plans for securing the cyberdefenses of their water and wastewater systems by May 20. When contacted by IEEE Spectrum about the results and responses from Neuberger’s summons, a U.S. State Department spokesperson declined to comment.
Everyone with a Roku TV or streaming device will eventually be forced to enable two-factor authentication after the company disclosed two separate incidents in which roughly 600,000 customers had their accounts accessed through credential stuffing.
Credential stuffing is an attack in which usernames and passwords exposed in one leak are tried out against other accounts, typically using automated scripts. When people reuse usernames and passwords across services or make small, easily intuited changes between them, actors can gain access to accounts with even more identifying information and access.
In the case of the Roku attacks, that meant access to stored payment methods, which could then be used to buy streaming subscriptions and Roku hardware. Roku wrote on its blog, and in a mandated data breach report, that purchases occurred in "less than 400 cases" and that full credit card numbers and other "sensitive information" was not revealed.
Attackers have transformed hundreds of hacked sites running WordPress software into command-and-control servers that force visitors’ browsers to perform password-cracking attacks.
A web search for the JavaScript that performs the attack showed it was hosted on 708 sites at the time this post went live on Ars, up from 500 two days ago. Denis Sinegubko, the researcher who spotted the campaign, said at the time that he had seen thousands of visitor computers running the script, which caused them to reach out to thousands of domains in an attempt to guess the passwords of usernames with accounts on them.
Visitors unwittingly recruited
“This is how thousands of visitors across hundreds of infected websites unknowingly and simultaneously try to bruteforce thousands of other third-party WordPress sites,” Sinegubko wrote. “And since the requests come from the browsers of real visitors, you can imagine this is a challenge to filter and block such requests.”
Google could be working on a password-sharing functionality within Google Password Manager that is distributed through Google Play Services.
The feature was spotted within Play Services, and the UI was activated through a feature.
It could allow accounts within a family group to share usernames and passwords easily through the Google Password Manager.
The future of the internet is passkeys, but passwords will still be around for a while. While Google has been pushing for passkey adoption, it hasn’t forgotten about passwords just yet. Google has been spotted working on a password-sharing feature for Android, making sharing your passwords with your family easier.
The latest Google Play Services v24.09.12 (190400-610662703) includes a password-sharing functionality, which TheSpAndroid has managed to activate the feature with a feature flag to give us an idea of what it looks like.
