CISA, NSA, FBI, and similar organizations in the other Five Eyes countries are warning that attacks on MSPs—as a vector to their customers—are likely to increase. No details about what this prediction is based on. Makes sense, though. The SolarWinds attack was incredibly successful for the Russian SVR, and a blueprint for future attacks.

The Department of Energy, CISA, the FBI, and the NSA jointly issued an advisory describing a sophisticated piece of malware called Pipedream that’s designed to attack a wide range of industrial control systems. This is clearly from a government, but no attribution is given. There’s also no indication of how the malware was discovered. It seems not to have been used yet.
The White House has issued its starkest warning that Russia may be planning cyberattacks against critical-sector U.S. companies amid the Ukraine invasion.
Context: The alert comes after Russia has lobbed a series of digital attacks at the Ukrainian government and critical industry sectors. But there’s been no sign so far of major disruptive hacks against U.S. targets even as the government has imposed increasingly harsh sanctions that have battered the Russian economy.
- The public alert followed classified briefings government officials conducted last week for more than 100 companies in sectors at the highest risk of Russian hacks, Neuberger said. The briefing was prompted by “preparatory activity” by Russian hackers, she said.
- U.S. analysts have detected scanning of some critical sectors’ computers by Russian government actors and other preparatory work, one U.S. official told my colleague Ellen Nakashima on the condition of anonymity because of the matter’s sensitivity. But whether that is a signal that there will be a cyberattack on a critical system is not clear, Neuberger said.
- Neuberger declined to name specific industry sectors under threat but said they’re part of critical infrastructure —a government designation that includes industries deemed vital to the economy and national security, including energy, finance, transportation and pipelines.
EDITED TO ADD (3/23): Long—three hour—conference call with CISA.
This will be law soon:
Companies critical to U.S. national interests will now have to report when they’re hacked or they pay ransomware, according to new rules approved by Congress.
The reporting requirement legislation was approved by the House and the Senate on Thursday and is expected to be signed into law by President Joe Biden soon. It requires any entity that’s considered part of the nation’s critical infrastructure, which includes the finance, transportation and energy sectors, to report any “substantial cyber incident” to the government within three days and any ransomware payment made within 24 hours.
Even better would be if they had to report it to the public.
According to a report from CISA last week, there were three ransomware attacks against water treatment plants last year.
WWS Sector cyber intrusions from 2019 to early 2021 include:
- In August 2021, malicious cyber actors used Ghost variant ransomware against a California-based WWS facility. The ransomware variant had been in the system for about a month and was discovered when three supervisory control and data acquisition (SCADA) servers displayed a ransomware message.
- In July 2021, cyber actors used remote access to introduce ZuCaNo ransomware onto a Maine-based WWS facility’s wastewater SCADA computer. The treatment system was run manually until the SCADA computer was restored using local control and more frequent operator rounds.
- In March 2021, cyber actors used an unknown ransomware variant against a Nevada-based WWS facility. The ransomware affected the victim’s SCADA system and backup systems. The SCADA system provides visibility and monitoring but is not a full industrial control system (ICS).
It’s a matter of going after those with deep pockets. From Wired:
Cloudflare was sued in November 2018 by Mon Cheri Bridals and Maggie Sottero Designs, two wedding dress manufacturers and sellers that alleged Cloudflare was guilty of contributory copyright infringement because it didn’t terminate services for websites that infringed on the dressmakers’ copyrighted designs….
[Judge] Chhabria noted that the dressmakers have been harmed “by the proliferation of counterfeit retailers that sell knock-off dresses using the plaintiffs’ copyrighted images” and that they have “gone after the infringers in a range of actions, but to no avail—every time a website is successfully shut down, a new one takes its place.” Chhabria continued, “In an effort to more effectively stamp out infringement, the plaintiffs now go after a service common to many of the infringers: Cloudflare. The plaintiffs claim that Cloudflare contributes to the underlying copyright infringement by providing infringers with caching, content delivery, and security services. Because a reasonable jury could not—at least on this record—conclude that Cloudflare materially contributes to the underlying copyright infringement, the plaintiffs’ motion for summary judgment is denied and Cloudflare’s motion for summary judgment is granted.”
I was an expert witness for Cloudflare in this case, basically explaining to the court how the service works.
Most US critical infrastructure is run by private corporations. This has major security implications, because it’s putting a random power company in—say—Ohio—up against the Russian cybercommand, which isn’t a fair fight.
When this problem is discussed, people regularly quote the statistic that 85% of US critical infrastructure is in private hands. It’s a handy number, and matches our intuition. Still, I have never been able to find a factual basis, or anyone who knows where the number comes from. Paul Rosenzweig investigates, and reaches the same conclusion.
So we don’t know the percentage, but I think we can safely say that it’s a lot.
Lukasz Olejnik has a good essay on hacking weapons systems.
Basically, there is no reason to believe that software in weapons systems is any more vulnerability free than any other software. So now the question is whether the software can be accessed over the Internet. Increasingly, it is. This is likely to become a bigger problem in the near future. We need to think about future wars where the tech simply doesn’t work.
Really good op-ed in the New York Times about how vulnerable the GPS system is to interference, spoofing, and jamming—and potential alternatives.
The 2018 National Defense Authorization Act included funding for the Departments of Defense, Homeland Security and Transportation to jointly conduct demonstrations of various alternatives to GPS, which were concluded last March. Eleven potential systems were tested, including eLoran, a low-frequency, high-power timing and navigation system transmitted from terrestrial towers at Coast Guard facilities throughout the United States.
“China, Russia, Iran, South Korea and Saudi Arabia all have eLoran systems because they don’t want to be as vulnerable as we are to disruptions of signals from space,” said Dana Goward, the president of the Resilient Navigation and Timing Foundation, a nonprofit that advocates for the implementation of an eLoran backup for GPS.
Also under consideration by federal authorities are timing systems delivered via fiber optic network and satellite systems in a lower orbit than GPS, which therefore have a stronger signal, making them harder to hack. A report on the technologies was submitted to Congress last week.
GPS is a piece of our critical infrastructure that is essential to a lot of the rest of our critical infrastructure. It needs to be more secure.
A water treatment plant in Oldsmar, Florida, was attacked last Friday. The attacker took control of one of the systems, and increased the amount of sodium hydroxide—that’s lye—by a factor of 100. This could have been fatal to people living downstream, if an alert operator hadn’t noticed the change and reversed it.
We don’t know who is behind this attack. Despite its similarities to a Russian attack of a Ukrainian power plant in 2015, my bet is that it’s a disgruntled insider: either a current or former employee. It just doesn’t make sense for Russia to be behind this.
ArsTechnica is reporting on the poor cybersecurity at the plant:
The Florida water treatment facility whose computer system experienced a potentially hazardous computer breach last week used an unsupported version of Windows with no firewall and shared the same TeamViewer password among its employees, government officials have reported.
Brian Krebs points out that the fact that we know about this attack is what’s rare:
Spend a few minutes searching Twitter, Reddit or any number of other social media sites and you’ll find countless examples of researchers posting proof of being able to access so-called “human-machine interfaces”—basically web pages designed to interact remotely with various complex systems, such as those that monitor and/or control things like power, water, sewage and manufacturing plants.
And yet, there have been precious few known incidents of malicious hackers abusing this access to disrupt these complex systems. That is, until this past Monday, when Florida county sheriff Bob Gualtieri held a remarkably clear-headed and fact-filled news conference about an attempt to poison the water supply of Oldsmar, a town of around 15,000 not far from Tampa.
