“Where Service and Technical Skills Count”

By Elizabeth Montalbano
Three vulnerabilities in the platform’s API Management Service could allow access sensitive data, mount further attacks, and even hijack developer portals.

Microsoft has patched three vulnerabilities in its Azure cloud platform that could have allowed attackers to access sensitive info on a targeted service, deny access to the server, or scan the internal network to mount further attacks, researchers have found.

Researchers from the Ermetic Research Team discovered the flaws in the Azure API Management Service, which allows organizations to create, manage, secure, and monitor APIs across all of their environments, they revealed in a blog post published May 4.

The flaws — all rated high-risk — include two Server-Side Request Forgery (SSRF) vulnerabilities and a file upload path traversal on an internal Azure workload.

SSRF allows an attacker to send a crafted request from a vulnerable server to a targeted external or internal server or service, or even target it in a denial-of-service (DoS) attack. Abusing these flaws means an attacker can access sensitive data stored on the targeted server, overload targeted servers using DoS attacks, and scan the internal network and identify potential targets for further attacks.

The third flaw is one in which Azure does not validate the file type and path of uploaded files. Typically in the case of this type of flaw, authenticated users can traverse the path specified to upload malicious files to the developer portal server and possibly execute code on it using DLL hijacking, IISNode config swapping, or any other similar attack vectors, the researchers said.

Microsoft responded quickly to Ermetic’s disclosure of the flaws and has fully patched them, according to the researchers, and no further action is necessary for Azure customers.
Details on the Bugs

Specifically, the Ermetic researchers discovered two separate SSRF flaws: one that affected the Azure API Management CORS Proxy and another that affected the Azure API Management Hosting Proxy.

They discovered the former on Dec. 21, 2022, and at first believed it was the same flaw that was first reported to Microsoft by another cloud security company on Nov. 12, and fixed a few days later on Nov. 16. However, the researchers later realized that the flaw they found actually bypasses that initial fix. Microsoft ultimately patched the vulnerability fully in January, the initial researchers reported later, according to Ermetic.

Together, the Azure SSRF flaws that researchers discovered affected central servers that “masses of users and organizations depend on for day-to-day operations,” says Liv Matan, cloud security researcher at Ermetic.

“Using them, attackers could fake requests from these legitimate servers, access internal services that may contain sensitive information belonging to Azure customers, and even prevent the availability of the vulnerable servers,” he says.

The path-traversal flaw found in Azure API Management Service allowed for an unrestricted file upload to the Azure developer portal server, the researchers said. The developer portal’s authenticated mode allowed someone to upload static files and images that would be shown on a developer’s dedicated portal, they said.

The flaw could have allowed attackers to take advantage of Microsoft’s self-hosted developer portal as well as weaponize the vulnerability against end users, Matan explains.

“Additionally, the Azure-hosted developer portal contains customer information that would have been at risk if the vulnerability had fallen into the wrong hands,” he says.
How to Protect the Enterprise

While API flaws like the ones Ermetic researchers discovered are uncommon, awareness of these types of vulnerabilities has grown in the past few years, Matan says.

Moreover, “blind SSRFs” — SSRF flaws that do not necessarily return any data but rather focus on performing unauthorized actions on the server’s backend — are fairly common, especially in cloud platforms that offer a wide range of services, he says.

Microsoft already had previously patched four SSRF flaws in four separate services of its Azure cloud platform, two of which could have allowed attackers to perform a server-side request forgery (SSRF) attack — and thus potentially execute remote code execution — even without authentication to a legitimate account.

“In the end, vulnerabilities can be discovered in any cloud platform, at any time,” Matan says.

There’s certainly been evidence of this, as — aside from SSRF flaws — researchers already have found a number of other flaws in Azure as well as other cloud platforms that could have threatened enterprise environments.

In one instance, Microsoft patched what researchers called a “dangerous” flaw in its Azure Service Fabric component that, if exploited, would have allowed an unauthenticated, malicious actor to execute code on a container hosted on the platform.

Because it’s difficult for an enterprise deploying a cloud to have control over or even be aware of a flaw on the underlying cloud-hosting infrastructure, it’s important for organizations to be vigilant in their own security practices so they are prepared if a flaw is eventually discovered or exploited, the researchers said.

In the case of avoiding compromising in the recently discovered Azure API Management, Matan recommends that organizations should practice proper input-validation hygiene and configure their servers to not follow redirects.

“To avoid a compromise in these cases, organizations should validate all input received from untrusted sources, such as user inputs or HTTP requests,” he says.

Other steps organizations can take to avoid compromise in these cases, Matan adds, include using a whitelist approach, implementing a strong firewall to restrict outgoing traffic from the application to only necessary services and ports, isolating data, and managing permissions on the server in cloud environments using IMDSv2.

Does this surprise you???
By Bill Toulas March 9, 2023

Microsoft’s Security Intelligence team recently investigated a business email compromise (BEC) attack and found that attackers move rapidly, with some steps taking mere minutes.

The whole process, from signing in using compromised credentials to registering typosquatting domains and hijacking an email thread, took the threat actors only a couple of hours.

This rapid attack progression ensures that the targets will have minimal opportunity to identify signs of fraud and take preventive measures.

A multi-billion problem

BEC attacks are a type of cyberattack where the attacker gains access to an email account of the target organization through phishing, social engineering, or buying account credentials on the dark web.

The attacker then impersonates a trusted individual, such as a senior executive or a supplier, to trick an employee working in the financial department into approving a fraudulent wire transfer request.

According to FBI data, from June 2016 until July 2019, BEC attacks resulted in losses amounting to over $43 billion, and this concerns only the cases reported to the law enforcement agency.

In a Twitter thread, Microsoft’s analysts explain that a recently investigated BEC attack began with the threat actor performing an “adversary-in-the-middle” (AiTM) phishing attack to steal the target’s session cookie, bypassing MFA protection.

The attacker logged in to the victim’s account on January 5, 2023, and spent two hours searching the mailbox for good email threads to hijack.

Thread hijacking is a very effective technique making it appear that the fraudulent message is a continuation of an existing communication exchange, so the recipients are far more likely to trust it.

After that, the attacker registered deceptive domains using homoglyph characters to make them appear almost identical to the sites of the target organization and the impersonated partner.

Five minutes later, the attacker created an inbox rule to siphon emails from the partner organization to a specific folder.

In the next minute, the attacker sent the malicious email to the business partner asking for a wire transfer instruction change and immediately deleted the sent message to reduce the likelihood of the compromised user discovering the breach.

From the first sign-in to the deletion of the sent email, a total of 127 minutes had passed, reflecting a rush from the attacker’s side.

Microsoft 365 Defender generated a warning about BEC financial fraud 20 minutes after the threat actor deleted the sent email and automatically disrupted the attack by disabling the user’s account.

“In our testing and evaluation of BEC detections and actions in customer environments faced with real-world attack scenarios, dozens of organizations were better protected when accounts were automatically disabled by Microsoft 365 Defender,” claims Microsoft.

“The new automatic disruption capabilities leave the SOC team in full control to investigate all actions taken by Microsoft 365 Defender and where needed, heal any remaining, affected assets.”

Microsoft says its security product has disrupted 38 BEC attacks targeting 27 organizations using high-confidence eXtended Detection and Response (XDR) signals across endpoints, identities, email, and SaaS apps.

Drop Go Daddy !!

 

The same “sophisticated” threat actor has pummeled the domain host on an ongoing basis since 2020, making off with customer logins, source code, and more. Here’s what to do.

Nate Nelson
Contributing Writer, Dark Reading

For years, the domain registrar and Web hosting company GoDaddy has experienced a cyber barrage of extraordinary scale, it has confirmed — affecting both the company and its many individual and enterprise clients.

As described in its 10K filing for 2022, released Feb. 16, the company has been breached once every year since 2020 by the same set of cyberattackers, with the latest occurring just last December. It’s worth also mentioning that the company has been the subject of earlier cyber incursions as well. The consequences to GoDaddy are one thing, but, more notably, the breaches have led to data compromises for more than 1 million of the company’s users.

That may well be the key to why the bad guys keep coming back. Because of the nature of its business, GoDaddy is a connecting link to millions of businesses around the world. As Brad Hong, customer success lead at Horizon3ai puts it: “This is the equivalent of your landlord’s office being left unlocked, giving a bad actor access to the keys to your house.”
GoDaddy’s Three-Headed Breach

While the world was coming to grips with COVID-19, thousands of GoDaddy customers had a second problem on their hands. In March 2020, the company discovered that an attacker had compromised the login details for a small number of their employees, as well as 28,000 of their hosting customers.

It was a harbinger of worse things to come.

In November 2021, a threat actor got their hands on a password that allowed them access to Managed WordPress, GoDaddy’s hosting platform for building and managing WordPress sites. This case touched 1.2 million Managed WordPress customers.

There was yet more. In a statement published alongside its 10K, GoDaddy shared details of yet a third compromise.

“In early December 2022, we started receiving a small number of customer complaints about their websites being intermittently redirected,” the company said. It turned out that an attacker had breached and planted malware on the company’s hosting servers for cPanel, a control panel program for Web hosts. This malware intermittently redirected users from the websites they intended to visit, to malicious sites.

In their statement, the company claimed to “have evidence, and law enforcement has confirmed, that this incident was carried out by a sophisticated and organized group targeting hosting services like GoDaddy. According to information we have received, their apparent goal is to infect websites and servers with malware for phishing campaigns, malware distribution, and other malicious activities.”
The Supply Chain Problem With Hosting Services

According to Domain Name Stat, GoDaddy is far and away the largest domain name registrar on the Internet, capturing more than 12% market share with its nearly 80 million registered domains. Scale, alone, would make it an attractive target for cyberattacks, but being a hosting service makes this a whole other animal.

“GoDaddy and other Web hosting sites are prime targets for adversaries looking to conduct supply chain attacks,” says Allie Roblee, intelligence analyst at Resilience. A company may take care to implement strong security practices and software, shunting phishing attacks, and patching up software bugs, yet still be vulnerable through a trusted provider like their Web hosting service. “Breaching large service providers like GoDaddy allows adversaries to compromise organizations and individuals they may have been unable to get into directly.”

Of course, once attackers get in through the side entrance, they can do anything from stealing credentials to dropping malware, redirecting users to malicious sites, planting backdoors for later use, and much more. But “the implications for these compromises go even beyond that of security,” Hong warns.

Consider an innocent person who intends to visit a business’s website, but instead ends up redirected to a malicious site. Would that person ever risk visiting that business’ website again? This, Hong points out, “hurts the reputation and operations of thousands, if not millions, of legitimate businesses.”

Beyond that, there’s a broader cost. “Weak security at this vendor level additionally allows attackers to force multiply their ability to carry out whatever objective they wish to,” he explains. Such compromises “not only provide them with rich PII and private key data intelligence, but also an extensive network of websites and servers to do their bidding — similar to an IoT botnet, but instead of multiplying traffic, it multiplies the chances of successfully carrying out attacks which rely on humans as a weakness.”
What GoDaddy Customers Can Do

If it didn’t end that first or second time, how likely is it that the campaign against GoDaddy is over now? “It’s possible,” Roblee warns, “that the attackers still have access to GoDaddy’s infrastructure or have the capability to find vulnerabilities in the stolen source code they can exploit to regain access.”

For that reason, she says, “customers should audit any recently changed or uploaded files on their website to ensure that malware has not been installed. Additionally, I would recommend checking historical DNS records to see if any of their domains had been temporarily redirected.”

Hong’s advice is even simpler. “Affected businesses should change everything!” including all potentially affected login credentials, “and especially deprecating and creating fresh SSL private keys if using them.”

Preventative measures will be more necessary going forward than ever before. As GoDaddy assessed in their 10K, the risk of attack “is likely to increase as we expand the number of cloud-based products we offer and operate in more countries.”

GoDaddy declined to comment for this article beyond its published statement when contacted by Dark Reading.
