In May 2025, the U.S. government sanctioned a Chinese national for operating a cloud provider linked to the majority of virtual currency investment scam websites reported to the FBI. But a new report finds the accused continues to operate a slew of established accounts at American tech companies — including Facebook, Github, PayPal and Twitter/X.
On May 29, the U.S. Department of the Treasury announced economic sanctions against Funnull Technology Inc., a Philippines-based company alleged to provide infrastructure for hundreds of thousands of websites involved in virtual currency investment scams known as “pig butchering.” In January 2025, KrebsOnSecurity detailed how Funnull was designed as a content delivery network that catered to foreign cybercriminals seeking to route their traffic through U.S.-based cloud providers.
The Treasury also sanctioned Funnull’s alleged operator, a 40-year-old Chinese national named Liu “Steve” Lizhi. The government says Funnull directly facilitated financial schemes resulting in more than $200 million in financial losses by Americans, and that the company’s operations were linked to the majority of pig butchering scams reported to the FBI.
It is generally illegal for U.S. companies or individuals to transact with people sanctioned by the Treasury. However, as Mr. Lizhi’s case makes clear, just because someone is sanctioned doesn’t necessarily mean big tech companies are going to suspend their online accounts.
The government says Lizhi was born November 13, 1984, and used the nicknames “XXL4” and “Nice Lizhi.” Nevertheless, Steve Liu’s 17-year-old account on LinkedIn (in the name “Liulizhi”) had hundreds of followers (Lizhi’s LinkedIn profile helpfully confirms his birthday) until quite recently: The account was deleted this morning, just hours after KrebsOnSecurity sought comment from LinkedIn.
Mr. Lizhi’s LinkedIn account was suspended sometime in the last 24 hours, after KrebsOnSecurity sought comment from LinkedIn.
In an emailed response, a LinkedIn spokesperson said the company’s “Prohibited countries policy” states that LinkedIn “does not sell, license, support or otherwise make available its Premium accounts or other paid products and services to individuals and companies sanctioned by the U.S. government.” LinkedIn declined to say whether the profile in question was a premium or free account.
Mr. Lizhi also maintains a working PayPal account under the name Liu Lizhi and username “@nicelizhi,” another nickname listed in the Treasury sanctions. A 15-year-old Twitter/X account named “Lizhi” that links to Mr. Lizhi’s personal domain remains active, although it has few followers and hasn’t posted in years.
These accounts and many others were flagged by the security firm Silent Push, which has been tracking Funnull’s operations for the past year and calling out U.S. cloud providers like Amazon and Microsoft for failing to more quickly sever ties with the company.

In a report released today, Silent Push found Lizhi still operates numerous Facebook accounts and groups, including a private Facebook account under the name Liu Lizhi. Another Facebook account clearly connected to Lizhi is a tourism page for Ganzhou, China called “EnjoyGanzhou” that was named in the Treasury Department sanctions.
“This guy is the technical administrator for the infrastructure that is hosting a majority of scams targeting people in the United States, and hundreds of millions have been lost based on the websites he’s been hosting,” said Zach Edwards, senior threat researcher at Silent Push. “It’s crazy that the vast majority of big tech companies haven’t done anything to cut ties with this guy.”
The FBI says it received nearly 150,000 complaints last year involving digital assets and $9.3 billion in losses — a 66 percent increase from the previous year. Investment scams were the top crypto-related crimes reported, with $5.8 billion in losses.
In a statement, a Meta spokesperson said the company continuously takes steps to meet its legal obligations, but that sanctions laws are complex and varied. They explained that sanctions are often targeted in nature and don’t always prohibit people from having a presence on its platform. Nevertheless, Meta confirmed it had removed the account, unpublished Pages, and removed Groups and events associated with the user for violating its policies.
Attempts to reach Mr. Lizhi via his primary email addresses at Hotmail and Gmail bounced as undeliverable. Likewise, his 14-year-old YouTube channel appears to have been taken down recently.
However, anyone interested in viewing or using Mr. Lizhi’s 146 computer code repositories will have no problem finding GitHub accounts for him, including one registered under the NiceLizhi and XXL4 nicknames mentioned in the Treasury sanctions.
One of multiple GitHub profiles used by Liu “Steve” Lizhi, who uses the nickname XXL4 (a moniker listed in the Treasury sanctions for Mr. Lizhi).
Mr. Lizhi also operates a GitHub page for an open source e-commerce platform called NexaMerchant, which advertises itself as a payment gateway working with numerous American financial institutions. Interestingly, this profile’s “followers” page shows several other accounts that appear to be Mr. Lizhi’s. All of the account’s followers are tagged as “suspended,” even though that suspended message does not display when one visits those individual profiles.
In response to questions, GitHub said it has a process in place to identify when users and customers are Specially Designated Nationals or other denied or blocked parties, but that it locks those accounts instead of removing them. According to its policy, GitHub takes care that users and customers aren’t impacted beyond what is required by law.
All of the follower accounts for the XXL4 GitHub account appear to be Mr. Lizhi’s, and have been suspended by GitHub, but their code is still accessible.
“This includes keeping public repositories, including those for open source projects, available and accessible to support personal communications involving developers in sanctioned regions,” the policy states. “This also means GitHub will advocate for developers in sanctioned regions to enjoy greater access to the platform and full access to the global open source community.”
Edwards said it’s great that GitHub has a process for handling sanctioned accounts, but that the process doesn’t seem to communicate risk in a transparent way, noting that the only indicator on the locked accounts is the message, “This repository has been archived by the owner. It is not read-only.”
“It’s an odd message that doesn’t communicate, ‘This is a sanctioned entity, don’t fork this code or use it in a production environment’,” Edwards said.
Mark Rasch is a former federal cybercrime prosecutor who now serves as counsel for the New York City based security consulting firm Unit 221B. Rasch said when Treasury’s Office of Foreign Assets Control (OFAC) sanctions a person or entity, it then becomes illegal for businesses or organizations to transact with the sanctioned party.
Rasch said financial institutions have very mature systems for severing accounts tied to people who become subject to OFAC sanctions, but that tech companies may be far less proactive — particularly with free accounts.
“Banks have established ways of checking [U.S. government sanctions lists] for sanctioned entities, but tech companies don’t necessarily do a good job with that, especially for services that you can just click and sign up for,” Rasch said. “It’s potentially a risk and liability for the tech companies involved, but only to the extent OFAC is willing to enforce it.”

In July 2024, Funnull purchased the domain polyfill[.]io, the longtime home of a legitimate open source project that allowed websites to ensure that devices using legacy browsers could still render content in newer formats. After the Polyfill domain changed hands, at least 384,000 websites were caught in a supply-chain attack that redirected visitors to malicious sites. According to the Treasury, Funnull used the code to redirect people to scam websites and online gambling sites, some of which were linked to Chinese criminal money laundering operations.
The U.S. government says Funnull provides domain names for websites on its purchased IP addresses, using domain generation algorithms (DGAs) — programs that generate large numbers of similar but unique names for websites — and that it sells web design templates to cybercriminals.
“These services not only make it easier for cybercriminals to impersonate trusted brands when creating scam websites, but also allow them to quickly change to different domain names and IP addresses when legitimate providers attempt to take the websites down,” reads a Treasury statement.
Meanwhile, Funnull appears to be morphing nearly all aspects of its business in the wake of the sanctions, Edwards said.
“Whereas before they might have used 60 DGA domains to hide and bounce their traffic, we’re seeing far more now,” he said. “They’re trying to make their infrastructure harder to track and more complicated, so for now they’re not going away but more just changing what they’re doing. And a lot more organizations should be holding their feet to the fire.”
Update, 2:48 PM ET: Added response from Meta, which confirmed it has closed the accounts and groups connected to Mr. Lizhi.
Update, July 7, 6:56 p.m. ET: In a written statement, PayPal said it continually works to combat and prevent the illicit use of its services.
“We devote significant resources globally to financial crime compliance, and we proactively refer cases to and assist law enforcement officials around the world in their efforts to identify, investigate and stop illegal activity,” the statement reads.
“Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.” -U.S. Constitution, First Amendment.

In an address to Congress this month, President Trump claimed he had “brought free speech back to America.” But barely two months into his second term, the president has waged an unprecedented attack on the First Amendment rights of journalists, students, universities, government workers, lawyers and judges.
This story explores a slew of recent actions by the Trump administration that threaten to undermine all five pillars of the First Amendment to the U.S. Constitution, which guarantees freedoms concerning speech, religion, the media, the right to assembly, and the right to petition the government and seek redress for wrongs.
The right to petition allows citizens to communicate with the government, whether to complain, request action, or share viewpoints — without fear of reprisal. But that right is being assaulted by this administration on multiple levels. For starters, many GOP lawmakers are now heeding their leadership’s advice to stay away from local town hall meetings and avoid the wrath of constituents affected by the administration’s many federal budget and workforce cuts.
Another example: President Trump recently fired most of the people involved in processing Freedom of Information Act (FOIA) requests for government agencies. FOIA is an indispensable tool used by journalists and the public to request government records, and to hold leaders accountable.
The biggest story by far this week was the bombshell from The Atlantic editor Jeffrey Goldberg, who recounted how he was inadvertently added to a Signal group chat with National Security Advisor Michael Waltz and 16 other Trump administration officials discussing plans for an upcoming attack on Yemen.
One overlooked aspect of Goldberg’s incredible account is that by planning and coordinating the attack on Signal — which features messages that can auto-delete after a short time — administration officials were evidently seeking a way to avoid creating a lasting (and potentially FOIA-able) record of their deliberations.
“Intentional or not, use of Signal in this context was an act of erasure—because without Jeffrey Goldberg being accidentally added to the list, the general public would never have any record of these communications or any way to know they even occurred,” Tony Bradley wrote this week at Forbes.
Petitioning the government, particularly when it ignores your requests, often requires challenging federal agencies in court. But that becomes far more difficult if the most competent law firms start to shy away from cases that may involve crossing the president and his administration.
On March 22, the president issued a memorandum that directs heads of the Justice and Homeland Security Departments to “seek sanctions against attorneys and law firms who engage in frivolous, unreasonable and vexatious litigation against the United States,” or in matters that come before federal agencies.
The POTUS recently issued several executive orders railing against specific law firms with attorneys who worked legal cases against him. On Friday, the president announced that the law firm of Skadden, Arps, Slate, Meager & Flom had agreed to provide $100 million in pro bono work on issues that he supports.
Trump issued another order naming the firm Paul, Weiss, Rifkind, Wharton & Garrison, which ultimately agreed to pledge $40 million in pro bono legal services to the president’s causes.
Other Trump executive orders targeted law firms Jenner & Block and WilmerHale, both of which have attorneys that worked with special counsel Robert Mueller on the investigation into Russian interference in the 2016 election. But this week, two federal judges in separate rulings froze parts of those orders.
“There is no doubt this retaliatory action chills speech and legal advocacy, and that is qualified as a constitutional harm,” wrote Judge Richard Leon, who ruled against the executive order targeting WilmerHale.
President Trump recently took the extraordinary step of calling for the impeachment of federal judges who rule against the administration. Trump called U.S. District Judge James Boasberg a “Radical Left Lunatic” and urged he be removed from office for blocking deportation of Venezuelan alleged gang members under a rarely invoked wartime legal authority.
In a rare public rebuke to a sitting president, U.S. Supreme Court Justice John Roberts issued a statement on March 18 pointing out that “For more than two centuries, it has been established that impeachment is not an appropriate response to disagreement concerning a judicial decision.”
The U.S. Constitution provides that judges can be removed from office only through impeachment by the House of Representatives and conviction by the Senate. The Constitution also states that judges’ salaries cannot be reduced while they are in office.
Undeterred, House Speaker Mike Johnson this week suggested the administration could still use the power of its purse to keep courts in line, and even floated the idea of wholesale eliminating federal courts.
“We do have authority over the federal courts as you know,” Johnson said. “We can eliminate an entire district court. We have power of funding over the courts, and all these other things. But desperate times call for desperate measures, and Congress is going to act, so stay tuned for that.”
President Trump has taken a number of actions to discourage lawful demonstrations at universities and colleges across the country, threatening to cut federal funding for any college that supports protests he deems “illegal.”
A Trump executive order in January outlined a broad federal crackdown on what he called “the explosion of antisemitism” on U.S. college campuses. This administration has asserted that foreign students who are lawfully in the United States on visas do not enjoy the same free speech or due process rights as citizens.
Reuters reports that the acting civil rights director at the Department of Education on March 10 sent letters to 60 educational institutions warning they could lose federal funding if they don’t do more to combat anti-semitism. On March 20, Trump issued an order calling for the closure of the Education Department.
Meanwhile, U.S. Immigration and Customs Enforcement (ICE) agents have been detaining and trying to deport pro-Palestinian students who are legally in the United States. The administration is targeting students and academics who spoke out against Israel’s attacks on Gaza, or who were active in campus protests against U.S. support for the attacks. Secretary of State Marco Rubio told reporters Thursday that at least 300 foreign students have seen their visas revoked under President Trump, a far higher number than was previously known.
In his first term, Trump threatened to use the national guard or the U.S. military to deal with protesters, and in campaigning for re-election he promised to revisit the idea.
“I think the bigger problem is the enemy from within,” Trump told Fox News in October 2024. “We have some very bad people. We have some sick people, radical left lunatics. And I think they’re the big — and it should be very easily handled by, if necessary, by National Guard, or if really necessary, by the military, because they can’t let that happen.”
This term, Trump acted swiftly to remove the top judicial advocates in the armed forces who would almost certainly push back on any request by the president to use U.S. soldiers in an effort to quell public protests, or to arrest and detain immigrants. In late February, the president and Defense Secretary Pete Hegseth fired the top legal officers for the military services — those responsible for ensuring the Uniform Code of Military Justice is followed by commanders.
Military.com warns that the purge “sets an alarming precedent for a crucial job in the military, as President Donald Trump has mused about using the military in unorthodox and potentially illegal ways.” Hegseth told reporters the removals were necessary because he didn’t want them to pose any “roadblocks to orders that are given by a commander in chief.”
President Trump has sued a number of U.S. news outlets, including 60 Minutes, CNN, The Washington Post, The New York Times and other smaller media organizations for unflattering coverage.
In a $10 billion lawsuit against 60 Minutes and its parent Paramount, Trump claims they selectively edited an interview with former Vice President Kamala Harris prior to the 2024 election. The TV news show last month published transcripts of the interview at the heart of the dispute, but Paramount is reportedly considering a settlement to avoid potentially damaging its chances of winning the administration’s approval for a pending multibillion-dollar merger.
The president sued The Des Moines Register and its parent company, Gannett, for publishing a poll showing Trump trailing Harris in the 2024 presidential election in Iowa (a state that went for Trump). The POTUS also is suing the Pulitzer Prize board over 2018 awards given to The New York Times and The Washington Post for their coverage of purported Russian interference in the 2016 election.
Whether or not any of the president’s lawsuits against news organizations have merit or succeed is almost beside the point. The strategy behind suing the media is to make reporters and newsrooms think twice about criticizing or challenging the president and his administration. The president also knows some media outlets will find it more expedient to settle.
Trump also sued ABC News and George Stephanopoulos for stating that the president had been found liable for “rape” in a civil case [Trump was found liable of sexually abusing and defaming E. Jean Carroll]. ABC parent Disney settled that claim by agreeing to donate $15 million to the Trump Presidential Library.
Following the attack on the U.S. Capitol on Jan. 6, 2021, Facebook blocked President Trump’s account. Trump sued Meta, and after the president’s victory in 2024 Meta settled and agreed to pay Trump $25 million: $22 million would go to his presidential library, and the rest to legal fees. Meta CEO Mark Zuckerberg also announced Facebook and Instagram would get rid of fact-checkers and rely instead on reader-submitted “community notes” to debunk disinformation on the social media platform.
Brendan Carr, the president’s pick to run the Federal Communications Commission (FCC), has pledged to “dismantle the censorship cartel and restore free speech rights for everyday Americans.” But on January 22, 2025, the FCC reopened complaints against ABC, CBS and NBC over their coverage of the 2024 election. The previous FCC chair had dismissed the complaints as attacks on the First Amendment and an attempt to weaponize the agency for political purposes.
According to Reuters, the complaints call for an investigation into how ABC News moderated the pre-election TV debate between Trump and Biden, and appearances of then-Vice President Harris on 60 Minutes and on NBC’s “Saturday Night Live.”
Since then, the FCC has opened investigations into NPR and PBS, alleging that they are breaking sponsorship rules. The Center for Democracy & Technology (CDT), a think tank based in Washington, D.C., noted that the FCC is also investigating KCBS in San Francisco for reporting on the location of federal immigration authorities.
“Even if these investigations are ultimately closed without action, the mere fact of opening them – and the implicit threat to the news stations’ license to operate – can have the effect of deterring the press from news coverage that the Administration dislikes,” the CDT’s Kate Ruane observed.
Trump has repeatedly threatened to “open up” libel laws, with the goal of making it easier to sue media organizations for unfavorable coverage. But this week, the U.S. Supreme Court declined to hear a challenge brought by Trump donor and Las Vegas casino magnate Steve Wynn to overturn the landmark 1964 decision in New York Times v. Sullivan, which insulates the press from libel suits over good-faith criticism of public figures.
The president also has insisted on picking which reporters and news outlets should be allowed to cover White House events and participate in the press pool that trails the president. He barred the Associated Press from the White House and Air Force One over their refusal to call the Gulf of Mexico by another name.
And the Defense Department has ordered a number of top media outlets to vacate their spots at the Pentagon, including CNN, The Hill, The Washington Post, The New York Times, NBC News, Politico and National Public Radio.
“Incoming media outlets include the New York Post, Breitbart, the Washington Examiner, the Free Press, the Daily Caller, Newsmax, the Huffington Post and One America News Network, most of whom are seen as conservative or favoring Republican President Donald Trump,” Reuters reported.
Shortly after Trump took office again in January 2025, the administration began circulating lists of hundreds of words that government staff and agencies shall not use in their reports and communications.
The Brookings Institution notes that in moving to comply with this anti-speech directive, federal agencies have purged countless taxpayer-funded data sets from a swathe of government websites, including data on crime, sexual orientation, gender, education, climate, and global development.
The New York Times reports that in the past two months, hundreds of terabytes of digital resources analyzing data have been taken off government websites.
“While in many cases the underlying data still exists, the tools that make it possible for the public and researchers to use that data have been removed,” The Times wrote.
On Jan. 27, Trump issued a memo (PDF) that paused all federally funded programs pending a review of those programs for alignment with the administration’s priorities. Among those was ensuring that no funding goes toward advancing “Marxist equity, transgenderism, and green new deal social engineering policies.”
According to the CDT, this order is a blatant attempt to force government grantees to cease engaging in speech that the current administration dislikes, including speech about the benefits of diversity, climate change, and LGBTQ issues.
“The First Amendment does not permit the government to discriminate against grantees because it does not like some of the viewpoints they espouse,” the CDT’s Ruane wrote. “Indeed, those groups that are challenging the constitutionality of the order argued as much in their complaint, and have won an injunction blocking its implementation.”
On January 20, the same day Trump issued an executive order on free speech, the president also issued an executive order titled “Reevaluating and Realigning United States Foreign Aid,” which froze funding for programs run by the U.S. Agency for International Development (USAID). Among those were programs designed to empower civil society and human rights groups, journalists and others responding to digital repression and Internet shutdowns.
According to the Electronic Frontier Foundation (EFF), this includes many freedom technologies that use cryptography, fight censorship, protect freedom of speech, privacy and anonymity for millions of people around the world.
“While the State Department has issued some limited waivers, so far those waivers do not seem to cover the open source internet freedom technologies,” the EFF wrote about the USAID disruptions. “As a result, many of these projects have to stop or severely curtail their work, lay off talented workers, and stop or slow further development.”
On March 14, the president signed another executive order that effectively gutted the U.S. Agency for Global Media (USAGM), which oversees or funds media outlets including Radio Free Europe/Radio Liberty and Voice of America (VOA). The USAGM also oversees Radio Free Asia, which supporters say has been one of the most reliable tools used by the government to combat Chinese propaganda.
But this week, U.S. District Court Judge Royce Lamberth, a Reagan appointee, temporarily blocked USAGM’s closure by the administration.
“RFE/RL has, for decades, operated as one of the organizations that Congress has statutorily designated to carry out this policy,” Lamberth wrote in a 10-page opinion. “The leadership of USAGM cannot, with one sentence of reasoning offering virtually no explanation, force RFE/RL to shut down — even if the President has told them to do so.”
The Trump administration rescinded a decades-old policy that instructed officers not to take immigration enforcement actions in or near “sensitive” or “protected” places, such as churches, schools, and hospitals.
That directive was immediately challenged in a case brought by a group of Quakers, Baptists and Sikhs, who argued the policy reversal was keeping people from attending services for fear of being arrested on civil immigration violations. On Feb. 24, a federal judge agreed and blocked ICE agents from entering churches or targeting migrants nearby.
The president’s executive order allegedly addressing antisemitism came with a fact sheet that described college campuses as “infested” with “terrorists” and “jihadists.” Multiple faith groups expressed alarm over the order, saying it attempts to weaponize antisemitism and promote “dehumanizing anti-immigrant policies.”
The president also announced the creation of a “Task Force to Eradicate Anti-Christian Bias,” to be led by Attorney General Pam Bondi. Never mind that Christianity is easily the largest faith in America and that Christians are well-represented in Congress.
The Rev. Paul Brandeis Raushenbush, a Baptist minister and head of the progressive Interfaith Alliance, issued a statement accusing Trump of hypocrisy in claiming to champion religion by creating the task force.
“From allowing immigration raids in churches, to targeting faith-based charities, to suppressing religious diversity, the Trump Administration’s aggressive government overreach is infringing on religious freedom in a way we haven’t seen for generations,” Raushenbush said.
A statement from Americans United for Separation of Church and State said the task force could lead to religious persecution of those with other faiths.
“Rather than protecting religious beliefs, this task force will misuse religious freedom to justify bigotry, discrimination, and the subversion of our civil rights laws,” said Rachel Laser, the group’s president and CEO.
Where is President Trump going with all these blatant attacks on the First Amendment? The president has made no secret of his affection for autocratic leaders and “strongmen” around the world, and he is particularly enamored with Hungary’s far-right Prime Minister Viktor Orbán, who has visited Trump’s Mar-a-Lago resort twice in the past year.
A March 15 essay in The Atlantic by Hungarian investigative journalist András Pethő recounts how Orbán rose to power by consolidating control over the courts, and by building his own media universe while simultaneously placing a stranglehold on the independent press.
“As I watch from afar what’s happening to the free press in the United States during the first weeks of Trump’s second presidency — the verbal bullying, the legal harassment, the buckling by media owners in the face of threats — it all looks very familiar,” Pethő wrote. “The MAGA authorities have learned Orbán’s lessons well.”
A clever malware deployment scheme first spotted in targeted attacks last year has now gone mainstream. In this scam, dubbed “ClickFix,” the visitor to a hacked or malicious website is asked to distinguish themselves from bots by pressing a combination of keyboard keys that causes Microsoft Windows to download password-stealing malware.
ClickFix attacks mimic the “Verify You are a Human” tests that many websites use to separate real visitors from content-scraping bots. This particular scam usually starts with a website popup that looks something like this:
This malware attack pretends to be a CAPTCHA intended to separate humans from bots.
Clicking the “I’m not a robot” button generates a pop-up message asking the user to take three sequential steps to prove their humanity.
Executing this series of keypresses prompts Windows to download password-stealing malware.
Step 1 involves simultaneously pressing the keyboard key with the Windows icon and the letter “R,” which opens a Windows “Run” prompt that will execute any specified program that is already installed on the system.
Step 2 asks the user to press the “CTRL” key and the letter “V” at the same time, which pastes malicious code from the site’s virtual clipboard.
Step 3 — pressing the “Enter” key — causes Windows to download and launch malicious code through “mshta.exe,” a Windows program designed to run Microsoft HTML application files.
“This campaign delivers multiple families of commodity malware, including XWorm, Lumma stealer, VenomRAT, AsyncRAT, Danabot, and NetSupport RAT,” Microsoft wrote in a blog post on Thursday. “Depending on the specific payload, the specific code launched through mshta.exe varies. Some samples have downloaded PowerShell, JavaScript, and portable executable (PE) content.”
According to Microsoft, hospitality workers are being tricked into downloading credential-stealing malware by cybercriminals impersonating Booking.com. The company said attackers have been sending malicious emails impersonating Booking.com, often referencing negative guest reviews, requests from prospective guests, or online promotion opportunities — all in a bid to convince people to step through one of these ClickFix attacks.
In November 2024, KrebsOnSecurity reported that hundreds of hotels that use booking.com had been subject to targeted phishing attacks. Some of those lures worked, and allowed thieves to gain control over booking.com accounts. From there, they sent out phishing messages asking for financial information from people who’d just booked travel through the company’s app.
Earlier this month, the security firm Arctic Wolf warned about ClickFix attacks targeting people working in the healthcare sector. The company said those attacks leveraged malicious code stitched into the widely used physical therapy video site HEP2go that redirected visitors to a ClickFix prompt.
An alert (PDF) released in October 2024 by the U.S. Department of Health and Human Services warned that the ClickFix attack can take many forms, including fake Google Chrome error pages and popups that spoof Facebook.

The ClickFix attack — and its reliance on mshta.exe — is reminiscent of phishing techniques employed for years that hid exploits inside Microsoft Office macros. Malicious macros became such a common malware threat that Microsoft was forced to start blocking macros by default in Office documents that try to download content from the web.
Alas, the email security vendor Proofpoint has documented plenty of ClickFix attacks via phishing emails that include HTML attachments spoofing Microsoft Office files. When opened, the attachment displays an image of Microsoft Word document with a pop-up error message directing users to click the “Solution” or “How to Fix” button.

Organizations that wish to do so can take advantage of Microsoft Group Policy restrictions to prevent Windows from executing the “run” command when users hit the Windows key and the “R” key simultaneously.
