Recent backdoor implants and cyber-espionage attacks on their supply chains have African organizations looking to diversify beyond Chinese, American tech vendors.

Every night for five years, computers and network appliances from the headquarters of the African Union in Ethiopia — a facility built by Chinese firms — reportedly reached out to China-based systems and uploaded sensitive data. The espionage through the technology supply chain, which China's government denies, undermined the security of the pan-African organization.

The incident and more recent supply-chain breaches have underscored that reliance on foreign technological supply chains carries with it significant risks. While using a technology supply chain anchored in China was seen as a less constrained option than US and European options, the truth is that African nations need to evaluate the security of all their supply chains across applications, consumer devices, infrastructure, and service providers, according to a report published by the Africa Center for Strategic Studies, a research and academic center funded by the US Department of Defense.

"I don't think there's an African country that doesn't have some kind of interest in fostering a more robust technology industry and finding various ways to exert more ownership and agency over various aspects of the technology sector," says Nate Allen, associate professor at the Africa Center for Strategic Studies and the author of the report. "You are seeing increasing African interest in having more ownership and say over their technology supply chains."

Supply-chain security has become a major issue worldwide following malicious events, such as the WannaCry and NotPetya worms and the compromise of SolarWinds, as well as IT supply-chain failures, like this summer's CrowdStrike outage. The US government has voiced concerns over the extent to which US maritime ports are reliant on Chinese equipment and investment, and China has begun creating its own operating system and software ecosystem.

Similarly, African nations have become wary of information technology supplied by any number of foreign countries, including China, Russia, the US, and Europe. While African nations need the technology and investment, they are pursuing initiatives to reduce their reliance, says Mark Walker, vice president of data and analytics for the Middle East, Turkey, and Africa for IDC South Africa.

"The reality is that we live in a multidimensional, globally interconnected world, \[where\] development is reliant on significant capital investment and R&D to develop technology — often this is in limited supply across Africa," he says. "That said, many African nations are focusing on developing local software and technology skills in their populations to offset reliance on global players and also ensure that solutions are relevant to local market condition and needs. Education plays a significant role in this."

**China, US Dominate Africa's Tech Market**

Those efforts are still nascent, with the reality that the top technology suppliers in Africa come from China and the US. In mobile applications, for example, 36 of 2023's top-100 applications are from Chinese companies, while 23 are from US companies, according to a report from DataSparkle, a provider of data and analytics for emerging markets. Africa-based developers only account for only seven applications, mostly focused on digital cash and payment applications.

The US dominates the operating-system supply chain with Microsoft's Windows, Google's Android, and Apple's iOS dominating the field.

"If you're not China and you're not the United States, you just have a lot of dependencies in your technology supply chain, and there's no way around it — even to some extent, if you are China and the United States," ACSS's Allen says.

Yet, the 54 nations on the content have options. While foreign firms provide much of the technology, the African market continues to grow and the domestic technology sector continues to have the most insight into nation-by-nation needs.

"\[A\] detailed view of Africa’s technology sector reveals that it is not under the control of any one actor, and there are plenty of opportunities for Africans to assert agency," the ACSS report stated. "By further fostering diversity and competition within the tech sector, African governments can help mitigate the vulnerabilities that come from external actor influence."

**Future of Technology Supply Chains in Africa**

Companies entering the market should find ways to address the cybersecurity concerns of African customers, because if they don't, someone else will, says IDC South Africa's Walker.

"Competition is strong, and vendors are judged on their ability to supply relevant technologies and services at a fair price with solid \[local\] support structures," he says, adding that companies should understand "the local market dynamics, including economic and political realities and the local regulatory environments. Security issues faced in the Horn of Africa around Somalia are different to those faced in northern Nigeria and the Magreb, which again, differ significantly from southeast Africa."

Among incidents in Africa, Chinese hackers targeted Kenyan officials following the nation's trouble paying back loans from China, according to news reports published in 2023, while another incident involved a state-sponsored group targeting foreign-affairs ministries, embassies, and military forces in Africa in an operation dubbed Diplomatic Specter, according to a threat analysis published in May.

In addition, African officials have warned that an important technology supply chain for the continent — open-source software (OSS) — needs to be better secured to prevent malicious attacks.

"I don't think that Africans are naive, or any government around the world is naive — I think they know that, if you are being sold a technology product that is not domestically produced, then there's always going to be some kind of security risk there," says ACSS's Allen. "I think the question is, how can you mitigate that security risk?"

Companies working in the markets need to have an answer to that question, he says.

African Reliance on Foreign Suppliers Boosts Insecurity Concerns

Microsoft has announced a new Windows Resiliency Initiative as a way to improve security and reliability, as well as ensure that system integrity is not compromised.
The idea, the tech giant said, is to avoid incidents like that of CrowdStrike's earlier this July, enable more apps and users to be run without admin privileges, add controls surrounding the use of unsafe apps and drivers, and offer

Microsoft Launches Windows Resiliency Initiative to Boost Security and System Integrity

Since surfacing in August, the likely LockBit variant has claimed more than two dozen victims and appears poised to strike many more.

The purveyor of a rapidly emerging ransomware family being tracked as "Helldown" introduced a new Linux variant, targeting organizations across multiple sectors using VMware ESXi servers.

Several of the victims had Zyxel firewalls deployed as IPSec VPN access points at the time of breach, suggesting the attackers exploited a vulnerability or vulnerabilities in the technology to gain initial access, security researchers at Sekoia reported this week. Since surfacing in August, the group behind Helldown has quickly notched 31 victims, many of them US-based.

**Undocumented Zyxel Vulnerabilities?**

Available telemetry suggests the Zyxel flaw that the attackers are exploiting is undocumented, Seokia said. But Zyxel has issued fixes for multiple vulnerabilities in its firewalls after Helldown actors breached the company's network, also in August, and then leaked some 250GB worth of data. As of mid-November, no exploit code for any of these vulnerabilities appears to be publicly available, Sekoia said, while leaving open the possibility that the Helldown attackers could be exploiting any one of the vulnerabilities.

"Helldown is a notably active new intrusion set, as shown by its large number of victims," Sekoia researcher Jeremy Scion wrote this week. "Available data indicates that the group mainly targets Zyxel firewalls by exploiting undocumented vulnerabilities." Though the ransomware itself is standard fare, what makes the group dangerous is its apparent access to and effective use of undocumented vulnerability code, Scion noted.

Zyxel firewalls, like many other network and edge technologies, are a popular attacker target. Threat actors have been quick to exploit flaws in the company's products in various campaigns in the past, including one dubbed IZ1H9 that targeted Internet-of-Things (IoT) networks; another involving a Mirai variant; and another that hit Danish critical infrastructure.  

**A Troubling Shift**

Patrick Tiquet, vice president security and architecture at Keeper Security, viewed Helldown as a troubling shift in ransomware actor tactics. "While ransomware targeting Linux isn't unprecedented, Helldown's focus on VMware systems shows its operators are evolving to disrupt the virtualized infrastructures many businesses rely on," he said via email. "The message to security teams is clear: patch known vulnerabilities, monitor for unusual activity, and treat virtualized environments with the same vigilance as traditional ones."

Multiple security vendors have reported attacks involving Helldown since early August. Most of its victims have been small and medium sized businesses across different sectors, including transportation, manufacturing, healthcare, telecommunications, and IT services. Halycon, one of the first to spot Helldown, described the group as "highly aggressive" and capable of causing substantial disruption and financial losses to victims. According to Halycon, Helldown actors have a penchant for stealing large volumes of data from victims and threatening to leak the data unless it receives a ransom.

In a report earlier this month, Truesec perceived the threat actor as being more sophisticated in its initial compromise techniques compared to better known ransomware operators, such as the one behind Akira. In the attacks that Truesec analyzed, Helldown threat actors leveraged legitimate tools and other living-off-the-land techniques to execute their mission on a compromised network.

**Dangerous Adversary**

"Recent incidents showed that the group will thoroughly remove tools utilized during a compromise, as well as override the free disk space on the hard drive of different machines, in attempts to hinder the recovery process and reduce the effectiveness of file carving," Trusec observed. Helldown actors likely accessed victim environments directly from their Internet-facing Zyxel firewall, the security vendor posited. Once on a victim network, the threat actor used either TeamViewer or the default Windows RDP client for lateral movement, PowerShell for remote code execution, and Mimikatz to search for and retrieve credentials.

According to Sekoia, reports from multiple Helldown victims indicate that the attacker compromised Zyxel firewalls running firmware version 5.38. "Specifically, a file named zzz1.conf was uploaded, and a user account called OKSDW82A was created" on compromised systems, Scion noted. The attacker then used the temporary account to create an SSL VPN tunnel for accessing and pivoting further into the victim network.  

The attack chain included attempts by the threat actor to disable endpoint detection mechanisms using a tool called HRSword; leverage the domain controller's LDAP credentials to burrow deeper into the network; use certutil to download Advanced Port Scanner; use RDP or TeamViewer for remote access and lateral movement; and use PSExec for remote code execution.

Scion said Sekoia's analysis of the files that Helldown actors have published on their data leak site showed many of them to be unusually large and averaging around 70GB. The biggest file, in fact, weighed in at a hefty 431GB, which is noteworthy because ransomware actors typically tend to be more selective in the files they steal and use for extortion. The contents of the stolen files also tended to be more variable and random than usual for a ransomware operation. "The large volume and variety of data suggest that the attacker does not selectively choose which documents to steal," Scion said. "Instead, they appear to target data sources that store administrative files, such as PDFs and document scans, which typically contain sensitive information (personal, financial, etc.), thereby intensifying the pressure on victims."

Helldown's behavior itself is similar to that of Darkrace, a LockBit variant that first surfaced in August 2023 and may have been rebranded as Donex in February of this year. Though the links between the ransomware strains are not conclusive, there is a possibility that Helldown is a rebrand of Donex, Sekoia said.

Linux Variant of Helldown Ransomware Targets VMware ESXi Systems

A widespread social media campaign for EditProAI turns out to spread information stealers for both Windows and MacOS users.

A large social media campaign was launched to promote a free Artificial Intelligence (AI) video editor. If the “free” part of that campaign sounds too good to be true, then that’s because it was.

Instead of the video editor, users got information stealing malware. Lumma Stealer was installed on Windows machines and Atomic Stealer (AMOS) on Macs.

The campaign to promote the AI video editor was active on several social media platforms, like X, Facebook, and YouTube…

…and had been active for quite a while. as you can see from this tweet.

The criminals seem to have used a lot of accounts to promote their “product” as you can see from this search on X.

Some accounts were expressly created for this purpose, while others look like they may have been compromised accounts.

The campaign looks well organized, and looks so legitimate that it took quite a while before a researcher found out and tweeted about the threat.

When interested individuals follow the links, they’ll end up on a professional looking website—exactly what you would expect.

But if they click the “GET NOW” button, they’ll download the information stealer and infect their device. The file is called “Edit-ProAI-Setup-newest\_release.exe” for Windows, and “EditProAi\_v.4.36.dmg” for macOS.

Lumma is available through a Malware-as-a-Service (MaaS) model, where cybercriminals pay other cybercriminals for access to malicious software and its related infrastructure. Lumma steals information from cryptocurrency wallets and browser extensions, as well as two-factor authentication details. Lumma is often distributed via email campaigns, but nothing stops the cybercriminals from spreading it as a download for an AI editor, as they did here.

AMOS makes money for its operators by finding and stealing valuable information on the computers it infects, such as credit card details, authentication cookies, passwords and cryptocurrency. Besides stealing data from the web browsers themselves, AMOS can also steal data from browser extensions (plugins).

**What if you installed one of these?**

Both stealers are after login credentials and financial information, so there are a few things you’ll need to do.

*   Monitor your accounts. Banking and cryptocurrency information is a prime target for these information stealers, so check your accounts and monitor them closely.
*   Change all your passwords starting with the important ones, and if you’re not using a password manager already, now might be a good time to get one. It can help you create and store strong passwords.
*   Enable multi-factor-authentication (MFA) on all your important accounts.
*   Log out of all your important accounts on infected devices. These information stealers are capable of taking over some accounts by stealing cookies, even if you have MFA enabled.

Malwarebytes for Windows and Malwarebytes for Mac can detect the information stealers, and they block the EditProAI websites.

 Free AI editor lures in victims, installs information stealer instead on Windows and Mac 

A critical vulnerability in the Windows Kerberos authentication protocol poses a significant risk to millions of servers. Microsoft…

A critical vulnerability in the Windows Kerberos authentication protocol poses a significant risk to millions of servers. Microsoft addressed this issue in last week’s Patch Tuesday updates. Ensure these patches are installed to protect your systems.

Microsoft has released a patch for a critical vulnerability in **Microsoft Kerberos**, a widely used authentication protocol for verifying host or user identities. This flaw, allows attackers to send crafted requests to vulnerable systems to gain unauthorised access and remote code execution (RCE).

To exploit this flaw, an unauthenticated actor must leverage a cryptographic protocol vulnerability to achieve RCE, Microsoft explained in its **Patch Tuesday advisory**.

The vulnerability is tracked as **CVE-2024-43639** and has a CVSS score of 9.8 (critical severity). If left unpatched, it could lead to drastic consequences for organizations of all sizes, including data theft, system disruption, and even complete system compromise. The vulnerability is particularly concerning due to the widespread use of Windows Server and the ease with which attackers can exploit it. 

According to Censys investigation, shared with Hackread.com, there are over two million (2,274,340) exposed Windows Server instances, with 1,211,834 likely to be vulnerable. However, Censys’ research reveals that not all of these instances are vulnerable, as only servers configured with the Kerberos KDC proxy are affected.

“Note that displayed devices are only vulnerable when configured as a Kerberos KDC Proxy Protocol server,” Censys **blog post** read.

Over half of these devices were found with TCP/443 open, the default port for the KDC Proxy Protocol server, and researchers urge admins to confirm this protocol’s presence on their systems. 

For your information, KDC Proxy Protocol Servers allow clients to communicate with KDC servers over HTTPS, using Kerberos protocols like UDP/TCP 88 for Kerberos Authentication Service and Ticket Grating Service exchanges, and TCP 464 for Kerberos password changes. These protocols assume direct, reliable access to the KDC server, usually within the same network or VPN, and are typically used for services like Remote Desktop Gateway and DirectAccess.

Regarding the most impacted regions, Censys noted that 34% of these vulnerable servers are located in the United States, and 11% are associated with Armstrong Enterprise Communications, a managed IT provider. 

System administrators should patch all Windows Servers configured as KDC Proxy servers, disable unnecessary KDC Proxy services, and implement additional security measures like network segmentation and firewalls to minimize the risk of a cyberattack.

The urgency of this situation is critical as many servers are vulnerable and attackers constantly exploit these weaknesses. Quick patching and additional security measures can significantly reduce the **risk of cyberattacks**.

COMMENTARY

Shadow IT is what your business runs on while waiting for IT to provide an enterprise solution. It's your sales team buying licenses to an obscure software-as-a-service (SaaS) because it helps them get the job done. Or it's your finance team using an unapproved tool because the approved one is too clunky. Sometimes shadow IT exists specifically to bypass an overly annoying security mechanism — figuring out a way to forward business emails to your personal Gmail account because it's easier to view on mobile, for example.

You might hope shadow IT is a problem only for large enterprises, too big to centrally manage. My experience running a small startup suggests otherwise. We agonized over our choice of a productivity tools suite — considering pros and cons and balancing user experience with governability. And people are happy to use our tool of choice; they just also use other tools in parallel. We run on Google Workspace, but many of our employees use Office because they're used to it. We use Google Drive for file sharing, but we quickly learned some people prefer iCloud.

People's personal preferences play a significant role here. They want to get their jobs done, not worry about learning a new tool. Platforms make this tendency even worse. Many try to get you to use and rely on them for a long time before asking for added licensing. Consider local file saves on Windows or Mac. By default, every local file save actually gets saved in a directory backed up into Microsoft's or Apple's cloud.

A large enterprise might have more mature security controls to prevent use of unauthorized software, but it also has much more variety in the software people would like to use. The sheer size of an enterprise and the independence of different business units exacerbate the software spread even further. The standard industry security practice for controlling software usage combines bringing in security on every license purchase and restricting software and SaaS usage on the endpoint. While those tactics are useful, they are limited in scope. Paying out of pocket, which some users will do to get the software they want, bypasses enterprise procurement.

**Approved Apps Lead to Building Unapproved Apps**

Expanding the use of existing platforms into new and unapproved feature sets is even more pervasive. Did you purchase Office 365 for productivity or Salesforce for your sales reps? Congrats. You've now empowered your business users to build their own apps with the no-code/low-code platform bundled in. Unapproved uses of enterprise platforms also bypass SaaS usage controls. Enterprises can't block access to Microsoft or Salesforce, but through them users can send corporate data to unapproved systems.

With each new discovery of an unapproved system, the security team can either try to block it or bring it under their umbrella. Either way, it's an endless game of whack-a-mole. Some tools can help with this discovery, but they often lack context about how these systems are used and which are actually important to business functions.

What if we could ask every business user what systems they use in their day-to-day, regardless of corporate policies? And ask which of those are truly vital for the business? That could give us the ultimate list: a full mapping of shadow IT, coupled with its business importance. Unfortunately, that doesn't work — simply asking people likely won't result in a full list, and what end users find vital may be different from what management does.

**User-Built Tools Expose Shadow IT Network**

Enter citizen development, in which business users leverage low-code/no-code tools to streamline their processes, analyze their data, and build custom business applications for their use cases. To be relevant, these apps must connect to the data and processes that the business uses in practice. A citizen developer is not going to call IT to integrate their app with the approved corporate service; instead, they'll connect directly to what we call shadow IT.

Here's an example. Consider a sales team using an unapproved tool for lead tracking. To sync it with the approved CRM, they use no-code automation. By finding automations that connect to the CRM and following the data flow, we can easily find the unapproved tool and what type of data it holds.

Embracing citizen development can leave security teams at a much better spot — having visibility into what software the business actually runs on — if used right.

That "if" is very important. Citizen development introduces its fair share of security risks, which must be mitigated to avoid adverse effects. But by embracing citizen development, we're letting business users codify what used to be a copy-paste data integration. Following these processes will lead us directly to the most important elements of shadow IT.

Plus: An “AI granny” is wasting scammers’ time, a lawsuit goes after spyware-maker NSO Group’s executives, and North Korea–linked hackers take a crack at macOS malware.

In perhaps the most adorable hacker story of the year, a trio of technologists in India found an innovative way to circumvent Apple’s location restrictions on AirPod Pro 2s so they could enable the earbuds’ hearing aid feature for their grandmas. The hack involved a homemade Faraday cage, a microwave, and a lot of trial and error.

On the other end of the tech-advancements spectrum, the US military is currently testing an AI-enabled machine gun that is capable of auto-targeting swarms of drones. The Bullfrog, built by Allen Control Systems, is one of several advanced weapons technologies in the works to combat the growing threat of cheap, small drones on the battlefield.

The US Department of Justice announced this week that an 18-year-old from California has admitted to making or orchestrating more than 375 swatting attacks across the United States.

Then, of course, there’s the Donald Trump of it all. This week, we published a practical guide to protecting yourself from government surveillance. WIRED has covered the dangers of government surveillance for decades, of course. But when the president-elect is explicitly threatening to jail his political enemies—whoever that may be—now’s probably a good time to brush up on your digital best practices.

In addition to potential dragnet surveillance of US citizens, US Immigration and Customs Enforcement started ramping up its surveillance arsenal the day after Trump won reelection. Meanwhile, experts are expecting the incoming administration to roll back cybersecurity rules instituted under president Joe Biden while taking a harder line against adversarial state-sponsored hackers. And if all this political upheaval has you in the mood to protest, beware: An investigation copublished by WIRED and The Marshall Project found that mask bans instituted in several states add a complicated new layer to exercising freedom of speech.

In August 2016, approximately 120,000 bitcoin—at the time worth around $71 million—were stolen in a hack on the Bitfinex cryptocurrency exchange. Then in 2022, as the value of cryptocurrency had rocketed skywards, law enforcement officials in New York arrested husband and wife Ilya Lichtenstein and Heather Morgan in relation to the hack and laundering the much-inflated $4.5 billion of stolen cryptocurrency. (At the time, $3.6 billion of the funds were recouped by law enforcement investigators.)

This week, after pleading guilty in 2023, Lichtenstein was sentenced to five years of jail time for conducting the hack and laundering the profits. With subsequent cryptocurrency spikes and additional seizures related to the hack, the US government has now been able to recover more than $10 billion in assets. A series of operational security failures by Lichtenstein made much of the illicit cryptocurrency easy for officials to seize, but investigators also applied sophisticated crypto-tracing methods to unpick how the funds had been stolen and subsequently moved around.

Aside from the brazen scale of the heist, Lichtenstein and Morgan gained online prominence and ridicule after their arrests due to a series of Forbes articles written by Morgan and rap videos posted to YouTube under the name of “Razzlekhan.” Morgan, who also pleaded guilty, is due to be sentenced on November 18.

**An ‘AI Granny’ Is Wasting Phone Scammers’ Time**

Scammers are increasingly adopting AI as part of their criminal toolkits—using the technology to create deepfakes, translate scripts, and make their operations more efficient. But artificial intelligence is also being turned against the scammers. British telecoms firm Virgin Media and its mobile operator O2 have created a new “AI granny” that can answer phone calls from scammers and keep them talking. The system uses different AI models, according to The Register, that listen to what a scammer says and respond immediately. In one case, the company says it kept a scammer on the line for 40 minutes and has fed others fake personal information. Unfortunately, the system (at least at the moment) can’t directly answer calls made to your phone; instead, O2 created a specific phone number for the system, which the company says it has managed to get placed in lists of numbers that scammers call.

**Alleged NSO Group Spyware Victim Adds NSO Founders and Executive to Lawsuit**

In a new legal strategy for those attempting to hold commercial spyware vendors responsible, lawyer Andreu Van den Eynde, who was allegedly hacked with NSO Group spyware, is directly accusing two of the company’s founders, Omri Lavie and Shalev Hulio, and one of its executives, Yuval Somekh, of hacking crimes in a lawsuit. The Barcelona-based human rights nonprofit Iridia announced this week that it filed the complaint in a Catalan court. Van den Eynde was reportedly a victim of a hacking campaign that used NSO’s notorious Pegasus spyware against at least 65 Catalans. Van den Eynde and Iridia originally sued NSO Group in a Barcelona court in 2022 along with affiliates Osy Technologies and Q Cyber Technologies. “The people responsible for NSO Group have to explain their concrete activities,” a legal representative for Iridia and Van den Eynde wrote in the complaint, which was written in Catalan and translated by TechCrunch.

**North Korea-Backed Hackers Are Exploring New macOS Malware**

Research published this week by the mobile device management firm Jamf found that hackers who have been linked to North Korea have been working to implant malware inside macOS applications built with a particular open-source software development kit. The campaigns focused on cryptocurrency-related targets and involved infrastructure similar to systems that have been used by North Korea’s notorious Lazarus Group. It’s unclear if the activity resulted in actual victim compromise or if it was still in a testing phase.

Financially motivated and state-backed hackers have less occasion to use malware targeting Apple’s Mac computers than hacking tools that infect Microsoft Windows or Linux desktops and servers. So when Mac malware crops up, it’s typically a niche point, but it can also be a revealing indicator of trends and priorities among hackers.

Microsoft pulled its November 2024 Exchange security updates that it released earlier this month for Patch Tuesday due to them breaking email delivery.

This decision came after there were reports from admins saying that email had stopped flowing altogether.

The issue affects Microsoft Exchange customers who use transport rules, or mail flow rules, as well as data loss protection rules. The mail flow rules filter and redirect emails in transit, while the data loss protection rules ensure that sensitive information isn't being shared via email to an outside organization.

According to Microsoft, some customers found that the mail flow rules stopped periodically after they installed the update. It is now advising admins who are noticing this issue to uninstall the November security updates entirely until they're re-released.

"We are continuing the investigation and are working on a permanent fix to address this issue," Microsoft stated in an update regarding the issue. "We will release it when ready. We have also paused the rollout of November 2024 SU to Windows / Microsoft Update. Customers who might not use Transport or DLP rules and did not run into the issue with rules, can continue using the November SU update."
