April’s Patch Tuesday Brings Record Number of Fixes

By BrianKrebs

If only Patch Tuesdays came around infrequently — like total solar eclipse rare — instead of just creeping up on us each month like The Man in the Moon. Although to be fair, it would be tough for Microsoft to eclipse the number of vulnerabilities fixed in this month’s patch batch — a record 147 flaws in Windows and related software.

Yes, you read that right. Microsoft today released updates to address 147 security holes in Windows, Office, Azure, .NET Framework, Visual Studio, SQL Server, DNS Server, Windows Defender, Bitlocker, and Windows Secure Boot.

“This is the largest release from Microsoft this year and the largest since at least 2017,” said Dustin Childs, from Trend Micro’s Zero Day Initiative (ZDI). “As far as I can tell, it’s the largest Patch Tuesday release from Microsoft of all time.”

Tempering the sheer volume of this month’s patches is the middling severity of many of the bugs. Only three of April’s vulnerabilities earned Microsoft’s most-dire “critical” rating, meaning they can be abused by malware or malcontents to take remote control over unpatched systems with no help from users.

Most of the flaws that Microsoft deems “more likely to be exploited” this month are marked as “important,” which usually involve bugs that require a bit more user interaction (social engineering) but which nevertheless can result in system security bypass, compromise, and the theft of critical assets.

Ben McCarthy, lead cyber security engineer at Immersive Labs called attention to CVE-2024-20670, an Outlook for Windows spoofing vulnerability described as being easy to exploit. It involves convincing a user to click on a malicious link in an email, which can then steal the user’s password hash and authenticate as the user in another Microsoft service.

Another interesting bug McCarthy pointed to is CVE-2024-29063, which involves hard-coded credentials in Azure’s search backend infrastructure that could be gleaned by taking advantage of Azure AI search.

“This along with many other AI attacks in recent news shows a potential new attack surface that we are just learning how to mitigate against,” McCarthy said. “Microsoft has updated their backend and notified any customers who have been affected by the credential leakage.”

CVE-2024-29988 is a weakness that allows attackers to bypass Windows SmartScreen, a technology Microsoft designed to provide additional protections for end users against phishing and malware attacks. Childs said one of ZDI’s researchers found this vulnerability being exploited in the wild, although Microsoft doesn’t currently list CVE-2024-29988 as being exploited.

“I would treat this as in the wild until Microsoft clarifies,” Childs said. “The bug itself acts much like CVE-2024-21412 – a [zero-day threat from February] that bypassed the Mark of the Web feature and allows malware to execute on a target system. Threat actors are sending exploits in a zipped file to evade EDR/NDR detection and then using this bug (and others) to bypass Mark of the Web.”

Update, 7:46 p.m. ET: A previous version of this story said there were no zero-day vulnerabilities fixed this month. BleepingComputer reports that Microsoft has since confirmed that there are actually two zero-days. One is the flaw Childs just mentioned (CVE-2024-21412), and the other is CVE-2024-26234, described as a “proxy driver spoofing” weakness.

Satnam Narang at Tenable notes that this month’s release includes fixes for two dozen flaws in Windows Secure Boot, the majority of which are considered “Exploitation Less Likely” according to Microsoft.

“However, the last time Microsoft patched a flaw in Windows Secure Boot in May 2023 had a notable impact as it was exploited in the wild and linked to the BlackLotus UEFI bootkit, which was sold on dark web forums for $5,000,” Narang said. “BlackLotus can bypass functionality called secure boot, which is designed to block malware from being able to load when booting up. While none of these Secure Boot vulnerabilities addressed this month were exploited in the wild, they serve as a reminder that flaws in Secure Boot persist, and we could see more malicious activity related to Secure Boot in the future.”

Please consider backing up your data or your drive before updating, and drop a note in the comments here if you experience any issues applying these fixes.

Adobe today released nine patches tackling at least two dozen vulnerabilities in a range of software products, including Adobe After Effects, Photoshop, Commerce, InDesign, Experience Manager, Media Encoder, Bridge, Illustrator, and Adobe Animate.

KrebsOnSecurity needs to correct the record on a point mentioned at the end of March’s “Fat Patch Tuesday” post, which looked at new AI capabilities built into Adobe Acrobat that are turned on by default. Adobe has since clarified that its apps won’t use AI to auto-scan your documents, as the original language in its FAQ suggested.

“In practice, no document scanning or analysis occurs unless a user actively engages with the AI features by agreeing to the terms, opening a document, and selecting the AI Assistant or generative summary buttons for that specific document,” Adobe said earlier this month.

‘The Manipulaters’ Improve Phishing, Still Fail at Opsec

By BrianKrebs

Roughly nine years ago, KrebsOnSecurity profiled a Pakistan-based cybercrime group called “The Manipulaters,” a sprawling web hosting network of phishing and spam delivery platforms. In January 2024, The Manipulaters pleaded with this author to unpublish previous stories about their work, claiming the group had turned over a new leaf and gone legitimate. But new research suggests that while they have improved the quality of their products and services, these nitwits still fail spectacularly at hiding their illegal activities.

In May 2015, KrebsOnSecurity published a brief writeup about the brazen Manipulaters team, noting that they openly operated hundreds of web sites selling tools designed to trick people into giving up usernames and passwords, or deploying malicious software on their PCs.

Manipulaters advertisement for “Office 365 Private Page with Antibot” phishing kit sold on the domain heartsender,com. “Antibot” refers to functionality that attempts to evade automated detection techniques, keeping a phish deployed as long as possible. Image: DomainTools.

The core brand of The Manipulaters has long been a shared cybercriminal identity named “Saim Raza,” who for the past decade has peddled a popular spamming and phishing service variously called “Fudtools,” “Fudpage,” “Fudsender,” “FudCo,” etc. The term “FUD” in those names stands for “Fully Un-Detectable,” and it refers to cybercrime resources that will evade detection by security tools like antivirus software or anti-spam appliances.

A September 2021 story here checked in on The Manipulaters, and found that Saim Raza and company were prospering under their FudCo brands, which they secretly managed from a front company called We Code Solutions.

That piece worked backwards from all of the known Saim Raza email addresses to identify Facebook profiles for multiple We Code Solutions employees, many of whom could be seen celebrating company anniversaries gathered around a giant cake with the words “FudCo” painted in icing.

Since that story ran, KrebsOnSecurity has heard from this Saim Raza identity on two occasions. The first was in the weeks following the Sept. 2021 piece, when one of Saim Raza’s known email addresses — bluebtcus@gmail.com — pleaded to have the story taken down.

“Hello, we already leave that fud etc before year,” the Saim Raza identity wrote. “Why you post us? Why you destroy our lifes? We never harm anyone. Please remove it.”

Not wishing to be manipulated by a phishing gang, KrebsOnSecurity ignored those entreaties. But on Jan. 14, 2024, KrebsOnSecurity heard from the same bluebtcus@gmail.com address, apropos of nothing.

“Please remove this article,” Sam Raza wrote, linking to the 2021 profile. “Please already my police register case on me. I already leave everything.”

Asked to elaborate on the police investigation, Saim Raza said they were freshly released from jail.

“I was there many days,” the reply explained. “Now back after bail. Now I want to start my new work.”

Exactly what that “new work” might entail, Saim Raza wouldn’t say. But a new report from researchers at DomainTools.com finds that several computers associated with The Manipulaters have been massively hacked by malicious data- and password-snarfing malware for quite some time.

DomainTools says the malware infections on Manipulaters PCs exposed “vast swaths of account-related data along with an outline of the group’s membership, operations, and position in the broader underground economy.”

“Curiously, the large subset of identified Manipulaters customers appear to be compromised by the same stealer malware,” DomainTools wrote. “All observed customer malware infections began after the initial compromise of Manipulaters PCs, which raises a number of questions regarding the origin of those infections.”

A number of questions, indeed. The core Manipulaters product these days is a spam delivery service called HeartSender, whose homepage openly advertises phishing kits targeting users of various Internet companies, including Microsoft 365, Yahoo, AOL, Intuit, iCloud and ID.me, to name a few.

A screenshot of the homepage of HeartSender 4 displays an IP address tied to fudtoolshop@gmail.com. Image: DomainTools.

HeartSender customers can interact with the subscription service via the website, but the product appears to be far more effective and user-friendly if one downloads HeartSender as a Windows executable program. Whether that HeartSender program was somehow compromised and used to infect the service’s customers is unknown.

However, DomainTools also found the hosted version of HeartSender service leaks an extraordinary amount of user information that probably is not intended to be publicly accessible. Apparently, the HeartSender web interface has several webpages that are accessible to unauthenticated users, exposing customer credentials along with support requests to HeartSender developers.

“Ironically, the Manipulaters may create more short-term risk to their own customers than law enforcement,” DomainTools wrote. “The data table “User Feedbacks” (sic) exposes what appear to be customer authentication tokens, user identifiers, and even a customer support request that exposes root-level SMTP credentials–all visible by an unauthenticated user on a Manipulaters-controlled domain. Given the risk for abuse, this domain will not be published.”

This is hardly the first time The Manipulaters have shot themselves in the foot. In 2019, The Manipulaters failed to renew their core domain name — manipulaters[.]com — the same one tied to so many of the company’s past and current business operations. That domain was quickly scooped up by Scylla Intel, a cyber intelligence firm that focuses on connecting cybercriminals to their real-life identities.

Currently, The Manipulaters seem focused on building out and supporting HeartSender, which specializes in spam and email-to-SMS spamming services.

“The Manipulaters’ newfound interest in email-to-SMS spam could be in response to the massive increase in smishing activity impersonating the USPS,” DomainTools wrote. “Proofs posted on HeartSender’s Telegram channel contain numerous references to postal service impersonation, including proving delivery of USPS-themed phishing lures and the sale of a USPS phishing kit.”

Reached via email, the Saim Raza identity declined to respond to questions about the DomainTools findings.

“First [of] all we never work on virus or compromised computer etc,” Raza replied. “If you want to write like that fake go ahead. Second I leave country already. If someone bind anything with exe file and spread on internet its not my fault.”

Asked why they left Pakistan, Saim Raza said the authorities there just wanted to shake them down.

“After your article our police put FIR on my [identity],” Saim Raza explained. “FIR” in this case stands for “First Information Report,” which is the initial complaint in the criminal justice system of Pakistan.

“They only get money from me nothing else,” Saim Raza continued. “Now some officers ask for money again again. Brother, there is no good law in Pakistan just they need money.”

Saim Raza has a history of being slippery with the truth, so who knows whether The Manipulaters and/or its leaders have in fact fled Pakistan (it may be more of an extended vacation abroad). With any luck, these guys will soon venture into a more Western-friendly, “good law” nation and receive a warm welcome by the local authorities.

DarkMe Malware Targets Traders Using Microsoft SmartScreen Zero-Day Vulnerability

By Newsroom
A newly disclosed security flaw in the Microsoft Defender SmartScreen has been exploited as a zero-day by an advanced persistent threat actor called Water Hydra (aka DarkCasino) targeting financial market traders. Trend Micro, which began tracking the campaign in late December 2023, said it entails the exploitation of CVE-2024-21412, a security bypass vulnerability related to Internet

Fat Patch Tuesday, February 2024 Edition

By BrianKrebs

Microsoft Corp. today pushed software updates to plug more than 70 security holes in its Windows operating systems and related products, including two zero-day vulnerabilities that are already being exploited in active attacks.

Top of the heap on this Fat Patch Tuesday is CVE-2024-21412, a “security feature bypass” in the way Windows handles Internet Shortcut Files that Microsoft says is being targeted in active exploits. Redmond’s advisory for this bug says an attacker would need to convince or trick a user into opening a malicious shortcut file.

Researchers at Trend Micro have tied the ongoing exploitation of CVE-2024-21412 to an advanced persistent threat group dubbed “Water Hydra,” which they say has being using the vulnerability to execute a malicious Microsoft Installer File (.msi) that in turn unloads a remote access trojan (RAT) onto infected Windows systems.

The other zero-day flaw is CVE-2024-21351, another security feature bypass — this one in the built-in Windows SmartScreen component that tries to screen out potentially malicious files downloaded from the Web. Kevin Breen at Immersive Labs says it’s important to note that this vulnerability alone is not enough for an attacker to compromise a user’s workstation, and instead would likely be used in conjunction with something like a spear phishing attack that delivers a malicious file.

Satnam Narang, senior staff research engineer at Tenable, said this is the fifth vulnerability in Windows SmartScreen patched since 2022 and all five have been exploited in the wild as zero-days. They include CVE-2022-44698 in December 2022, CVE-2023-24880 in March 2023, CVE-2023-32049 in July 2023 and CVE-2023-36025 in November 2023.

Narang called special attention to CVE-2024-21410, an “elevation of privilege” bug in Microsoft Exchange Server that Microsoft says is likely to be exploited by attackers. Attacks on this flaw would lead to the disclosure of NTLM hashes, which could be leveraged as part of an NTLM relay or “pass the hash” attack, which lets an attacker masquerade as a legitimate user without ever having to log in.

“We know that flaws that can disclose sensitive information like NTLM hashes are very valuable to attackers,” Narang said. “A Russian-based threat actor leveraged a similar vulnerability to carry out attacks – CVE-2023-23397 is an Elevation of Privilege vulnerability in Microsoft Outlook patched in March 2023.”

Microsoft notes that prior to its Exchange Server 2019 Cumulative Update 14 (CU14), a security feature called Extended Protection for Authentication (EPA), which provides NTLM credential relay protections, was not enabled by default.

“Going forward, CU14 enables this by default on Exchange servers, which is why it is important to upgrade,” Narang said.

Rapid7’s lead software engineer Adam Barnett highlighted CVE-2024-21413, a critical remote code execution bug in Microsoft Office that could be exploited just by viewing a specially-crafted message in the Outlook Preview pane.

“Microsoft Office typically shields users from a variety of attacks by opening files with Mark of the Web in Protected View, which means Office will render the document without fetching potentially malicious external resources,” Barnett said. “CVE-2024-21413 is a critical RCE vulnerability in Office which allows an attacker to cause a file to open in editing mode as though the user had agreed to trust the file.”

Barnett stressed that administrators responsible for Office 2016 installations who apply patches outside of Microsoft Update should note the advisory lists no fewer than five separate patches which must be installed to achieve remediation of CVE-2024-21413; individual update knowledge base (KB) articles further note that partially-patched Office installations will be blocked from starting until the correct combination of patches has been installed.

It’s a good idea for Windows end-users to stay current with security updates from Microsoft, which can quickly pile up otherwise. That doesn’t mean you have to install them on Patch Tuesday. Indeed, waiting a day or three before updating is a sane response, given that sometimes updates go awry and usually within a few days Microsoft has fixed any issues with its patches. It’s also smart to back up your data and/or image your Windows drive before applying new updates.

For a more detailed breakdown of the individual flaws addressed by Microsoft today, check out the SANS Internet Storm Center’s list. For those admins responsible for maintaining larger Windows environments, it often pays to keep an eye on Askwoody.com, which frequently points out when specific Microsoft updates are creating problems for a number of users.

Apple & Microsoft Patch Tuesday, July 2023 Edition

By BrianKrebs

Microsoft Corp. today released software updates to quash 130 security bugs in its Windows operating systems and related software, including at least five flaws that are already seeing active exploitation. Meanwhile, Apple customers have their own zero-day woes again this month: On Monday, Apple issued (and then quickly pulled) an emergency update to fix a zero-day vulnerability that is being exploited on MacOS and iOS devices.

On July 10, Apple pushed a “Rapid Security Response” update to fix a code execution flaw in the Webkit browser component built into iOS, iPadOS, and macOS Ventura. Almost as soon as the patch went out, Apple pulled the software because it was reportedly causing problems loading certain websites. MacRumors says Apple will likely re-release the patches when the glitches have been addressed.

Launched in May, Apple’s Rapid Security Response updates are designed to address time-sensitive vulnerabilities, and this is the second month Apple has used it. July marks the sixth month this year that Apple has released updates for zero-day vulnerabilities — those that get exploited by malware or malcontents before there is an official patch available.

If you rely on Apple devices and don’t have automatic updates enabled, please take a moment to check the patch status of your various iDevices. The latest security update that includes the fix for the zero-day bug should be available in iOS/iPadOS 16.5.1, macOS 13.4.1, and Safari 16.5.2.

On the Windows side, there are at least four vulnerabilities patched this month that earned high CVSS (badness) scores and that are already being exploited in active attacks, according to Microsoft. They include CVE-2023-32049, which is a hole in Windows SmartScreen that lets malware bypass security warning prompts; and CVE-2023-35311 allows attackers to bypass security features in Microsoft Outlook.

The two other zero-day threats this month for Windows are both privilege escalation flaws. CVE-2023-32046 affects a core Windows component called MSHTML, which is used by Windows and other applications, like Office, Outlook and Skype. CVE-2023-36874 is an elevation of privilege bug in the Windows Error Reporting Service.

Many security experts expected Microsoft to address a fifth zero-day flaw — CVE-2023-36884 — a remote code execution weakness in Office and Windows.

“Surprisingly, there is no patch yet for one of the five zero-day vulnerabilities,” said Adam Barnett, lead software engineer at Rapid7. “Microsoft is actively investigating publicly disclosed vulnerability, and promises to update the advisory as soon as further guidance is available.”

Barnett notes that Microsoft links exploitation of this vulnerability with Storm-0978, the software giant’s name for a cybercriminal group based out of Russia that is identified by the broader security community as RomCom.

“Exploitation of CVE-2023-36884 may lead to installation of the eponymous RomCom trojan or other malware,” Barnett said. “[Microsoft] suggests that RomCom / Storm-0978 is operating in support of Russian intelligence operations. The same threat actor has also been associated with ransomware attacks targeting a wide array of victims.”

Microsoft’s advisory on CVE-2023-36884 is pretty sparse, but it does include a Windows registry hack that should help mitigate attacks on this vulnerability. Microsoft has also published a blog post about phishing campaigns tied to Storm-0978 and to the exploitation of this flaw.

Barnett said it’s while it’s possible that a patch will be issued as part of next month’s Patch Tuesday, Microsoft Office is deployed just about everywhere, and this threat actor is making waves.

“Admins should be ready for an out-of-cycle security update for CVE-2023-36884,” he said.

Microsoft also today released new details about how it plans to address the existential threat of malware that is cryptographically signed by…wait for it….Microsoft.

In late 2022, security experts at Sophos, Trend Micro and Cisco warned that ransomware criminals were using signed, malicious drivers in an attempt to evade antivirus and endpoint detection and response (EDR) tools.

In a blog post today, Sophos’s Andrew Brandt wrote that Sophos identified 133 malicious Windows driver files that were digitally signed since April 2021, and found 100 of those were actually signed by Microsoft. Microsoft said today it is taking steps to ensure those malicious driver files can no longer run on Windows computers.

As KrebsOnSecurity noted in last month’s story on malware signing-as-a-service, code-signing certificates are supposed to help authenticate the identity of software publishers, and provide cryptographic assurance that a signed piece of software has not been altered or tampered with. Both of these qualities make stolen or ill-gotten code-signing certificates attractive to cybercriminal groups, who prize their ability to add stealth and longevity to malicious software.

Dan Goodin at Ars Technica contends that whatever Microsoft may be doing to keep maliciously signed drivers from running on Windows is being bypassed by hackers using open source software that is popular with video game cheaters.

“The software comes in the form of two software tools that are available on GitHub,” Goodin explained. “Cheaters use them to digitally sign malicious system drivers so they can modify video games in ways that give the player an unfair advantage. The drivers clear the considerable hurdle required for the cheat code to run inside the Windows kernel, the fortified layer of the operating system reserved for the most critical and sensitive functions.”

Meanwhile, researchers at Cisco’s Talos security team found multiple Chinese-speaking threat groups have repurposed the tools—one apparently called “HookSignTool” and the other “FuckCertVerifyTimeValidity.”

“Instead of using the kernel access for cheating, the threat actors use it to give their malware capabilities it wouldn’t otherwise have,” Goodin said.

For a closer look at the patches released by Microsoft today, check out the always-thorough Patch Tuesday roundup from the SANS Internet Storm Center. And it’s not a bad idea to hold off updating for a few days until Microsoft works out any kinks in the updates: AskWoody.com usually has the lowdown on any patches that may be causing problems for Windows users.

And as ever, please consider backing up your system or at least your important documents and data before applying system updates. If you encounter any problems with these updates, please drop a note about it here in the comments.

Service Rents Email Addresses for Account Signups

By BrianKrebs

One of the most expensive aspects of any cybercriminal operation is the time and effort it takes to constantly create large numbers of new throwaway email accounts. Now a new service offers to help dramatically cut costs associated with large-scale spam and account creation campaigns, by paying people to sell their email account credentials and letting customers temporarily rent access to a vast pool of established accounts at major providers.

The service in question — kopeechka[.]store — is perhaps best described as a kind of unidirectional email confirmation-as-a-service that promises to “save your time and money for successfully registering multiple accounts.”

“Are you working on large volumes and are costs constantly growing?” Kopeechka’s website asks. “Our service will solve all your problems.”

As a customer of this service, you don’t get full access to the email inboxes you are renting. Rather, you configure your botnet or spam machine to make an automated application programming interface (API) call to the Kopeechka service, which responds with a working email address at an email provider of your choosing.

Once you’ve entered the supplied email address into the new account registration page at some website or service, you tell Kopeechka which service or website you’re expecting an account confirmation link from, and they will then forward any new messages matching that description to your Kopeechka account panel.

Ensuring that customers cannot control inboxes rented through the service means that Kopeechka can rent the same email address to multiple customers (at least until that email address has been used to register accounts at most of the major online services).

Kopeechka also has multiple affiliate programs, including one that pays app developers for embedding Kopeechka’s API in their software. However, far more interesting is their program for rewarding people who choose to sell Kopeechka usernames and passwords for working email addresses.

Kopeechka means “penny” in Russian, which is generous verbiage (and coinage) for a service that charges a tiny fraction of a penny for access to account confirmation links. Their pricing fluctuates slightly based on which email provider you choose, but a form on the service’s homepage says a single confirmation message from apple.com to outlook.com costs .07 rubles, which is currently equal to about $0.00087 dollars.

The pricing for Kopeechka works out to about a fraction of a penny per confirmation message.

“Emails can be uploaded to us for sale, and you will receive a percentage of purchases %,” the service explains. “You upload 1 mailbox of a certain domain, discuss percentage with our technical support (it depends on the liquidity of the domain and the number of downloaded emails).”

We don’t have to look very far for examples of Kopeechka in action. In May, KrebsOnSecurity interviewed a Russian spammer named “Quotpw who was mass-registering accounts on the social media network Mastodon in order to conduct a series of huge spam campaigns advertising scam cryptocurrency investment platforms.

Much of the fodder for that story came from Renaud Chaput, a freelance programmer working on modernizing and scaling the Mastodon project infrastructure — including joinmastodon.org, mastodon.online, and mastodon.social. Chaput told KrebsOnSecurity that his team was forced to temporarily halt all new registrations for these communities last month after the number of new registrations from Quotpw’s spam campaign started to overwhelm their systems.

“We suddenly went from like three registrations per minute to 900 a minute,” Chaput said. “There was nothing in the Mastodon software to detect that activity, and the protocol is not designed to handle this.”

After that story ran, Chaput said he discovered that the computer code powering Quotpw’s spam botnet (which has since been released as open source) contained an API call to Kopeechka’s service.

“It allows them to pool many bot-created or compromised emails at various providers and offer them to cyber criminals,” Chaput said of Kopeechka. “This is what they used to create thousands of valid Hotmail (and other) addresses when spamming on Mastodon. If you look at the code, it’s really well done with a nice API that forwards you the confirmation link that you can then fake click with your botnet.”

It’s doubtful anyone will make serious money selling email accounts to Kopeechka, unless of course that person already happens to run a botnet and has access to ridiculous numbers of email credentials. And in that sense, this service is genius: It essentially offers scammers a new way to wring extra income from resources that are already plentiful for them.

One final note about Quotpw and the spam botnet that ravaged Chaput’s Mastodon servers last month: Trend Micro just published a report saying Quotpw was spamming to earn money for a Russian-language affiliate program called “Impulse Team,” which pays people to promote cryptocurrency scams.

The crypto scam affiliate program “Project Impulse,” advertising in 2021.

Websites under the banner of the Impulse Scam Crypto Project are all essentially “advanced fee” scams that tell people they have earned a cryptocurrency investment credit. Upon registering at the site, visitors are told they need to make a minimum deposit on the service to collect the award. However, those who make the initial investment never hear from the site again, and their money is gone.

Interestingly, Trend Micro says the scammers behind the Impulse Team also appear to be operating a fake reputation service called Scam-Doc[.]com, a website that mimics the legitimate Scamdoc.com for measuring the trustworthiness and authenticity of various sites. Trend notes that the phony reputation site routinely gave high trust ratings to a variety of cryptocurrency scam and casino websites.

“We can only suppose that either the same cybercriminals run operations involving both or that several different cybercriminals share the scam-doc[.]com site,” the Trend researchers wrote.

According to the FBI, financial losses from cryptocurrency investment scams dwarfed losses for all other types of cybercrime in 2022, rising from $907 million in 2021 to $2.57 billion last year.
