IT infrastructure shortages are real and lasting. Here’s how to cope

Computerworld.com [Hacking News] - 12 Srpen, 2026 - 17:58

Lead times of nine to 12 or even 18 months. Costs rising by 35%, 45%, even 50% to 200%. More than halfway through 2026, the market for IT infrastructure that’s crucial for enterprise projects, including those involving artificial intelligence, is strapped.

Memory is at the root of the shortages. Memory prices “have risen by 50% to 200%, resulting in PC prices increasing by 35% to 45% and some server prices rising over 125%,” according to Jon Forest, VP analyst at Gartner. Network switches also need memory, albeit in lesser amounts than servers, so they are not immune, with prices and lead times likewise rising dramatically.

Industry experts agree that most of the issues stem from hyperscalers gobbling up memory capacity, which trickles down to servers, storage systems, and networking devices. But while the source of the problem may be new, supply chain disruptions are far from unprecedented.

As a result, industry insiders are not short on advice on how best to deal with the situation, with tips including making better use of what you have, considering options beyond your usual scope, and lots of planning with your vendors and internal finance teams.

State of the problem

Just how bad is the current supply chain problem? “It’s pretty bad,” says Matt Kimball, vice president and principal analyst with Moor Insights & Strategy. Companies accustomed to 30- to 45-day lead times for various infrastructure are now looking at 6, 12, or even 18 months.

“It’s real, and I’m hearing it from companies of all sizes, from the 1000-server to the 10,000-server shops,” Kimball says.

“Memory costs are expected to rise sharply well into 2027 and will reach up to 25% of network hardware expenses by the end of 2027,” according to an email Gartner’s Forest sent to Network World. The figure below shows the timeline Gartner expects for memory prices, and Forest notes that the same timing applies across networking, storage, and compute infrastructure. 

Gartner

“Enterprise network equipment pricing is projected to increase by over 20% in 2026. This upward trend is anticipated to continue with a further rise of 3% to 5% entering 2027, with no signs of price reduction until the end of 2027.”

But “reduction” will likely look more like “stabilization.”

“That’s something a lot of people don’t like to talk about. But let’s say prices went up 40%, they may come down five,” says Phillip Privett, senior vice president of vendor management with the global distributor and value-added reseller TD SYNNEX. “They’re not going to come down 40%.”

Perhaps worse, compared with past disruptions caused by issues such as fires in chip fabrication factories or the Covid pandemic, Kimball says this one is “durable” because its cause—the AI wave—is more long-lasting and just getting started.

“This AI inference wave we’re hitting is just beginning. It’s going to be longer and bigger than the training wave,” he says. “It’s impacting everything, from AI infrastructure to the traditional stuff that’s standing up your virtualization and cloud infrastructure.”

No vendors seem to be immune, not even the likes of Cisco, which makes its own Cisco Silicon One chips. Or, at least, it designs the chips; they’re actually manufactured by the Taiwan Semiconductor Manufacturing Company (TSMC), the same company that makes many of the other chips that are in such demand. And that’s only one component of many that comprise a switch.

On the other hand, the margins Cisco gets from enterprise sales are far greater than those from hyperscalers because Cisco sells mainly just hardware to hyperscalers, whereas enterprise sales generally include software and services as well. So, Cisco has incentive to keep enterprise customers happy and maintain the 66% margins it reported in Q3, its latest quarter.

Still, Cisco must deal with the same shortages as other vendors.

“I wouldn’t say any company is faring better than others,” says Neil Anderson, vice president and CTO for cloud, infrastructure, and AI solutions at World Wide Technology (WWT). “There may be nuances that some suppliers are employing to balance it to some extent, but I fail to recognize a supplier that’s not having almost the same issue.”

Cloud storage vendor Backblaze is one company that’s facing equipment cost and availability issues. “There are different types of shortages occurring in multiple places, all driven by unusual market demands, really by just a handful of very large buyers,” says James Rowell, senior vice president of operations with Backblaze.

Backblaze is constantly forecasting and monitoring demand triggers, Rowell says. That involves close alignment with the sales team to forecast client needs, as well as paying attention to historical trendlines to predict upcoming demand from new deals and growth with existing clients. But the company also looks for “unnatural market-related triggers” that would cause a spike in utilization.

With hyperscalers buying up vast amounts of capacity, “This is definitely an unnatural phase,” Rowell says. “For about for the last 12 months, I would say there’s been somewhere between a 15% and 30% uptick in costs,” especially in terms of servers and compute disks.

On the positive side, at least for Backblaze, the company is also seeing an uptick in business from an interesting source: AI companies. “We reported in the last earnings period a 70% increase in AI companies using our platform,” says Patrick Thomas, vice president of marketing at Backblaze. “That’s massive.”

On top of that, the company is seeing an uptick in deals from enterprises that can’t get the storage capacity they need or want on-prem. “There’s a general market nervousness where we’ve got potential deals coming our way because those organizations are concerned about being able to do it themselves,” Rowell says.

While some expect new chip fabrication plants currently under construction will ease memory supply constraints, Privett doesn’t buy it. “I don’t see it getting better anytime soon,” he says. “Building a new fab is a two-year process.”

Advice: Start with the basics

Enterprises, then, must play the cards they’re dealt. For Moore Insights’ Kimball, who did stints as an IT exec with the states of Florida and Oregon, that starts with making the most of what you have.

Such a strategy is “shockingly not implemented much” across the companies he sees. “A simple capacity planning exercise can free up a lot of resources.” That includes virtualized servers running at just 20% to 30% utilization as well as extending the life of existing servers. While 15 or 20 years ago it was common to refresh every four years or so, companies can often get six or seven years out of today’s servers.

While such strategies won’t solve your AI compute challenges, they can certainly help support your ongoing operations and free up budget for AI and other modernization projects, he says.

“Sweat your assets,” agrees Privett of TD SYNNEX. “Work them as much as you can, add only what you need, get extensions on your licensing, renewals on your services agreements and things like that. Just sweat it out a little longer.”

If you have budget to spend but can’t get the hardware you’re after, buy something else, says WWT’s Anderson. “Look at things that are not tied to those components, like software projects or SaaS licensing,” he says.

Get friendly with finance teams

Numerous experts recommend regular meetings with your CFO or finance teams to keep them apprised of what you’re up against so the company can plan accordingly.

Gartner’s Forest advises using rolling 12- to 24‑month forecasts and engaging early with suppliers to identify constrained components and SKUs. Committing to quarterly or monthly buys can help you avoid long-term agreements that extend past the rapid increases we’re seeing in 2026, he says.

Also engage with the financing arm of your equipment vendors, some of which are offering financing incentives, Privett says. Compute vendors in particular are offering subsidized financing, deferred payments, and low-cost financing for the first year or so. “Those are huge opportunities to take advantage of,” he says.

By engaging with finance teams, IT groups can conduct budget allocation exercises and try to come up with ways to make the financials work. The last thing you want to do is surprise them with additional budget requests out of the blue.

Kimball recalls his days with the state of Florida, when all budget requests were examined by a technical review working group—which was designed to be hostile.

“I can’t imagine going to them and saying, ‘Oh, did I say that was a million dollars? It’s actually $2 million. I need you to write me a bigger check,’” he says. “I would walk into one of the swamps in Tallahassee and get eaten by the alligators instead of doing that.”

Work with your vendors and VARs

As you put plans together, lean on your vendors for help, including channel partners such as value-added resellers (VAR) and national resellers. “Work with them to map things out and understand what your workloads will look like,” Kimball says.

That’s what Backblaze’s Rowell regularly does with his suppliers. He lays out his forecast for the year, with commitments on what Backblaze will definitely buy, as well as scenarios that account for rapid growth, say, 2x. “And they’ll come back with, ‘Well, okay, no problem,’ or maybe they say we need to put in an allocation right away, or we won’t be able to get what we may need,” he says.

Similarly, he sits down with his CFO regularly to map out predictive models that factor in inflation, price hikes, and the like. The idea is to plan out multiple scenarios, so you don’t get blindsided.

“If you don’t do that, you’ll get caught with your pants down, on the upside-down end of spectrum,” he said – meaning not having the capacity to take advantage of market opportunities.

Acquiring the capacity you need to meet project demand may also mean being flexible in terms of your equipment choices. If you’re a Dell shop but can’t get Dell servers, maybe you go with Lenovo, Kimball says.

“You’ve got to figure out how to use all this silicon and infrastructure in a heterogenous way to serve your needs,” he says. That’s especially true when it comes to AI infrastructure. “If you think you’re going to go with 100% Nvidia for everything from RAG [retrieval augmented generation] to inferencing at the edge, you’re kind of crazy, not because of cost but because of availability.”

Look at alternatives, including AMD and cloud solutions, while staying mindful of how it all plays together. You may not be able to get Nvidia GPUs, but AWS, Azure, and Oracle Cloud have them, Kimball notes.

Be strategic, perhaps by using cloud offerings to handle certain tuning or inference workloads, then bringing them back in-house when appropriate. “Have a better understanding of what absolutely has to be on prem and what can be in the cloud,” he says.

That’s good advice, says Backblaze’s Thomas. When it comes to AI, think about performance tiers and the range of use cases you have. They don’t all need top-tier performance.

“People get wrapped around axle of needing the top end. There’s a lot of flexibility in the edges, innovation in different hardware and software,” Thomas says.

Gartner likewise advises companies to increase configuration flexibility and expand sourcing paths. That may include buying from secondary markets and lease-return programs to preserve continuity with existing infrastructure until the shortages pass, Forest says.

Get started somewhere

Even if you can’t acquire or have to wait for the infrastructure you need, don’t let that keep you from getting started with AI or other modernization projects.

Options include public cloud and neocloud providers, Anderson says. WWT also provides capacity in its own lab so customers can get started with proof-of-concept projects. “Don’t just throw your hands up. We can help you find access to capacity,” Anderson says. “Production-scale AI may be delayed, but don’t let that derail your strategy.”

Colocation providers may likewise be an option, especially if enterprises are struggling to acquire high-end networking equipment. Networking is a key value proposition for colocation providers, in that they have built-in connections to various cloud providers and other ecosystem players.

Equinix, for example, has 280 data centers in 77 metropolitan areas, says Phil Read, senior director, colocation product management for the company. If you have the compute infrastructure, Equinix can help you with the high-end connectivity required both intra- data center and at edge facilities.

It also has partnerships with the likes of Cisco and Nvidia for “ready-to-go AI connectivity,” Read says. That means Equinix offers the right infrastructure to meet the requirements of high-end compute solutions in terms of power density and cooling. Such power densities are significant, requiring 120k VA per rack and up. “There’s plenty of talk about a megawatt rack,” he says.

Power is a significant issue in this entire discussion, Privett says. Older installed computing infrastructure likely consumes far more power than newer systems, which is an argument for upgrading as soon as possible.

“If you modernize today, you could substantially reduce the number of servers needed to support the same applications at a much lower power consumption rate,” Privett says. He advises sitting down with folks from the OT side of the house to make sure power is available for whatever you want to do. In many areas, power is at a premium.

If your plans include installing GPU environments in your own data center, WWT advises you not to delay. “We’re telling customers, you need to talk with us and get that designed, get that ordered, because it will take quite a bit of time until it actually ships and we’re able to install it,” Anderson says.

Uber Freight keeps on trucking after extortion crew breaks in

The Register - Anti-Virus - 12 Srpen, 2026 - 16:32
Uber Freight says it is investigating a "data security incident" days after the Helix extortion group listed the company on its data leak site on August 6. Helix claims to have stolen nearly 1 million files from mailboxes, OneDrive accounts, the accounts receivable department, and other repositories. An Uber Freight spokesperson told The Register that the incident was under investigation but had not disrupted the company's daily operations. "We are investigating a data security incident involving unauthorized access to a portion of Uber Freight's systems and repositories. The incident was identified, contained, and remediated, and we promptly engaged federal law enforcement. "There has been no impact to Uber Freight's business operations, which continue in the normal course without disruption. Our systems are secure and fully operational." Uber Freight is the ubiquitous ride-sharing company's lesser-known logistics arm, which describes itself as "one of North America's largest managed transportation and multimodal capacity networks." Its website claims that it manages 18 million shipments carrying more than $17 billion worth of goods each year. The Register did not download the files Helix released in stages, and Uber Freight neither confirmed nor denied that the material was authentic. Helix is one of several recently established extortion brands linked by researchers to infrastructure associated with BlackFile, which retired its name in May. According to Google Threat Intelligence Group (GTIG), Helix shares infrastructure with the Pink, Redact, and Falcon brands. Google tracks the wider cluster of activity as UNC6671. Operators associated with UNC6671 often use vishing to gain an initial foothold, posing as IT helpdesk staff overseeing mandatory security migrations, Google said. They contact employees on their personal phones and use device code phishing to obtain credentials and authenticated sessions before siphoning data from cloud services such as Microsoft 365. They have also targeted Okta identity infrastructure. Researchers believe the UNC6671-linked brands have recently shifted toward organizations in higher-value sectors. Since June, they have favored technology, transportation, and hospitality targets after focusing on manufacturing, real estate, healthcare, and insurance during April and May. Why multiple brands emerged after BlackFile shut down is unclear. GTIG said the strategy could "compartmentalize operations, hide overall breach volumes, and isolate any negotiation fallout," although other plausible explanations exist. Internal disagreements over matters such as handling finances and operational security could have led to the fragmentation of UNC6671, GTIG speculated. The core members may also be looking to retain control over the intrusion and data theft aspects of the attack, while outsourcing negotiations and extortion. The different groups may also just be using the same commoditized phishing tools. ®

Exposed: Woeful security at UK criminal records office that led to sensitive data leak

The Register - Anti-Virus - 12 Srpen, 2026 - 15:40
The UK's criminal records office, ACRO, has escaped a fine and received a regulatory reprimand after security failings potentially exposed highly sensitive data belonging to nearly 11,000 people. ACRO disclosed the "cybersecurity incident" in April 2023, and said at the time that it had no evidence to suggest that any data was compromised. However, it has now emerged that attackers maintained persistent access to ACRO's website and content management system for more than seven months, and staged sensitive data for possible exfiltration. According to the Information Commissioner's Office (ICO), which reprimanded ACRO rather than imposing a financial penalty, the breach was uncovered in March 2023 only because ACRO was investigating a separate intrusion. The watchdog said that while investigating an SQL injection attack that compromised 15 sets of credentials, most belonging to ACRO staff, investigators found evidence of separate intrusions dating back to July 8, 2021. The incidents fell into three categories, the ICO said. Some did not affect personal data, while others exposed only a small number of account credentials. The most serious involved ACRO's website and its Kentico content management system. The intrusion began on August 5, 2022, and the attackers maintained persistent access, without being detected, until March 14, 2023. The ICO found that ACRO ran version 12.0.0 of Kentico CMS from September 2019 until March 2023 without applying the patches and hotfixes released during that period, leaving known vulnerabilities unresolved. The ICO blamed poor communication between ACRO and its managed service provider. The supplier did not learn that patching was its responsibility until February 2020 and continued to assume that it was not required to monitor actively for security updates. "The ambiguity around who was accountable for identifying necessary Kentico CMS patches created a gap where patches and hotfixes were missed, which ultimately left ACRO's website vulnerable," the ICO said. Further, ACRO did not have a documented policy that covered patching Kentico CMS, nor could it demonstrate how vulnerabilities were identified or prioritized. ACRO's Trend Micro antivirus generated alerts, but nobody appears to have been minding them. The records office told the ICO that, for reasons redacted from the postmortem, it was "unable to establish what business processes existed for the assessment or handling of security alerts at the relevant time." It also could not identify which roles were responsible for reviewing these alerts at the time, ultimately resulting in them going unread. ACRO's poor logging means that, despite an extensive investigation by a third-party cybersecurity outfit, it remains impossible to determine whether the affected data was exfiltrated. Investigators did establish that the attackers staged the data for possible exfiltration between February 15 and 16, 2023. The potentially exposed material included: Police Certificate Applications Subject Access Request (SAR) forms and International Child Protection Certificate forms Names Dates of birth Addresses National Insurance numbers Passport and driving licence details Bank account information Biometric data Highly sensitive criminal offence and special category information ACRO notified 84,048 people of the breach, although investigators later determined that data relating to no more than 10,920 individuals had potentially been staged for exfiltration. Of these, ACRO received 35 formal complaints citing personal distress and concern about the risk of identity theft and financial loss, according to the ICO's reprimand document [PDF]. "Complainants included those connected to Police Certificates, International Child Protection Certificates, and victims of domestic violence." The ICO also received six complaints citing similar concerns. ACRO's saving grace was its network segmentation, which prevented the attackers from straying beyond the CMS into other systems, the ICO noted. Since the attack was discovered, ACRO has made a number of improvements to its security, including decommissioning the compromised infrastructure (although not until June 2023), implementing a SIEM, improving visibility, monitoring, and network segmentation, hardening systems, and migrating to Salesforce Experience Cloud. Jonathan Balmforth, group manager of civil and cyber investigations at the ICO, said: "This case highlights how basic cyber security failings can create significant risks for thousands of people, particularly where organizations process large volumes of highly sensitive personal information. "Organizations must ensure there is clear accountability for identifying, assessing and applying security updates. They must also have effective monitoring in place so that warning signs of cyberattacks are identified, investigated and acted upon promptly. "The lessons from this incident are clear. Having the right policies, responsibilities and oversight arrangements in place is just as important as having the right technology. "We welcome the improvements ACRO has made since these incidents. We hope other organizations will use this case as an opportunity to review their own processes and responses to ensure personal information remains properly protected." ACRO welcomed the reprimand from the ICO and highlighted the steps it has taken since to bolster its security. A spokesperson told The Register: "Since the cybersecurity incident was identified in March 2023, we have worked hard to strengthen our systems and safeguards. "In particular, we immediately took the previous website offline and subsequently decommissioned it. We also took steps to protect customers, including making sure anyone potentially affected was informed at the earliest possible stage." They went on to say: "We accept the ICO's findings of the infringements. We are grateful for the recognition from the Information Commissioner of the multiple remedial steps ACRO has taken in light of this incident and are committed to maintaining high standards of data protection and information security in future." ®

Akira ransomware scum blocked victim's security tools – and broke their own encryptor

The Register - Anti-Virus - 12 Srpen, 2026 - 15:00
An Akira ransomware affiliate rebooted a victim’s computer into Safe Mode to kill its security tools – and in the process sabotaged their own malware when the limited-function startup mode also broke their encryptor. “Akira's encryptor is engineered for speed, relying on concurrent worker threads and heavy memory mapping rather than simple sequential read-and-write operations. That high-performance design is likely what caused it to break in Safe Mode,” Huntress security operations analyst James Northey told The Register. “Safe Mode loads a minimal driver set, which can restrict storage controllers and pagefile availability,” he added. “A heavy, multi-threaded encryptor strains that constrained environment far more than the lighter, streamed-I/O designs used by other ransomware families.” But the ending wasn't entirely happy for the victim. The attacker had already stolen credentials and data from file shares before Safe Mode prevented the ransomware from doing its job. Northey detailed the incident in a Wednesday blog and cautioned that this was more likely a memory-configuration issue, and shouldn't be taken as a practical defense to prevent Akira ransomware from locking up valuable files. “Ultimately this could be a case of winning the battle, but not the war,” Northey wrote. “It’s possible that a host with more physical memory or a larger page file might give akira.exe enough virtual memory to encrypt the endpoint in Safe Mode,” Northey added. “Akira’s developers or affiliates could retool the encryptor to reduce its memory demands or make its Safe Mode launch sequence more reliable, meaning that the same failure may not occur in a future intrusion.” Nonetheless, there's one big lesson here: For the love of all that is holy, turn on multi-factor authentication (MFA). Here’s a closer look at what happened, and how to prevent it from happening to you. How it started… In early August, Huntress responded to an incident that began, as most Akira intrusions do, with a SonicWall SSL VPN. On August 4, the VPN logged a credential-spray attack: a burst of failed logins using bad credentials that it denied. But then, seven minutes later, one of them succeeded when the attacker used a valid VPN account that wasn’t protected by MFA. Once they had gained access, the criminal accessed the domain controller via Remote Desktop Protocol (RDP) and queried Active Directory to hoover up detailed information about the network, users, groups, computers – essentially everything an attacker needs to know about who and what to target for lateral movement and mass encryption in a ransomware attack. “The enumeration was a full-property dump of every user and every computer in the domain,” Northey wrote. The Akira ransomware affiliate then moved to the application server to start collecting stolen data, downloading WinRAR and using that tool to archive mapped file shares before sending the stolen data to cloud storage using s5cmd, a fast S3 transfer utility. They also installed remote desktop software AnyDesk, configured to start with Windows, and abused this legitimate tool as a remote-access trojan, giving the attacker hands-on keyboard control. They also used it as a command-and-control channel to drop more malware, including the very cleverly named akira.exe ransomware binary – because no one would guess what that executable could be, right? Then came the Safe Mode reboot Here’s where things went sideways for the ransomware scumbag. About three hours into the intrusion, the attacker forced the computer to reboot into Safe Mode with Networking, a boot mode that only loads essential drivers and services, blocking most third-party software. Attackers, especially ransomware gangs, do this to disable endpoint detection and response products and other security tools that would otherwise detect and stop their malware from infecting victims’ machines. While some ransomware crews, including Snatch and AvosLocker, have abused Safe Mode for this purpose for years, Huntress has never seen Akira do it until now. In this case, the reboot stopped the Huntress agent and disabled Microsoft Defender's real-time protection, preventing Defender from quarantining the malicious file. “The attacker got their blind window,” Northey wrote. “What they didn't get was a clean detonation.” Thirteen seconds after the reboot, the computer started spewing memory errors. Safe Mode boots with constrained virtual memory, and it didn’t have sufficient memory to encrypt the endpoint. Essentially, Safe Mode not only acted as an EDR killer, but also borked the ransomware. In addition to the obvious recommendations – like make sure you receive alerts on bursts of failed VPN logins against multiple usernames from one source, and require MFA on every VPN account – Huntress suggests organizations keep an eye out for this Safe Mode play. Specifically, “alert on boot-configuration changes and Safe Mode boots: msconfig.exe / bcdedit activity, Kernel-Boot EID 27 with a SAFEBOOT load option, Kernel-General EID 12 BootMode=2, and third-party security services stopping (System EID 7036),” Northey wrote. Also, “watch for tooling being added to the Safe Mode minimal-service registry list.” ®
