Hackers Stole Access Tokens from Okta’s Support Unit

October 20, 2023

Okta, a company that provides identity tools like multi-factor authentication and single sign-on to thousands of businesses, has suffered a security breach involving a compromise of its customer support unit, KrebsOnSecurity has learned. Okta says the incident affected a “very small number” of customers, however it appears the hackers responsible had access to Okta’s support platform for at least two weeks before the company fully contained the intrusion.

In an advisory sent to an undisclosed number of customers on Oct. 19, Okta said it “has identified adversarial activity that leveraged access to a stolen credential to access Okta’s support case management system. The threat actor was able to view files uploaded by certain Okta customers as part of recent support cases.”

Okta explained that when it is troubleshooting issues with customers it will often ask for a recording of a Web browser session (a.k.a. an HTTP Archive or HAR file). These are sensitive files because they can include the customer’s cookies and session tokens, which intruders can then use to impersonate valid users.

“Okta has worked with impacted customers to investigate, and has taken measures to protect our customers, including the revocation of embedded session tokens,” their notice continued. “In general, Okta recommends sanitizing all credentials and cookies/session tokens within a HAR file before sharing it.”

The security firm BeyondTrust is among the Okta customers who received Thursday’s alert from Okta. BeyondTrust Chief Technology Officer Marc Maiffret said that alert came more than two weeks after his company alerted Okta to a potential problem.

Maiffret emphasized that BeyondTrust caught the attack earlier this month as it was happening, and that none of its own customers were affected. He said that on Oct 2., BeyondTrust’s security team detected that someone was trying to use an Okta account assigned to one of their engineers to create an all-powerful administrator account within their Okta environment.

When BeyondTrust reviewed the activity of the employee account that tried to create the new administrative profile, they found that — just 30 minutes prior to the unauthorized activity — one of their support engineers shared with Okta one of these HAR files that contained a valid Okta session token, Maiffret said.

“Our admin sent that [HAR file] over at Okta’s request, and 30 minutes after that the attacker started doing session hijacking, tried to replay the browser session and leverage the cookie in that browser recording to act on behalf of that user,” he said.

Maiffret said BeyondTrust followed up with Okta on Oct. 3 and said they were fairly confident Okta had suffered an intrusion, and that he reiterated that conclusion in a phone call with Okta on October 11 and again on Oct. 13.

In an interview with KrebsOnSecurity, Okta’s Deputy Chief Information Security Officer Charlotte Wylie said Okta initially believed that BeyondTrust’s alert on Oct. 2 was not a result of a breach in its systems. But she said that by Oct. 17, the company had identified and contained the incident — disabling the compromised customer case management account, and invalidating Okta access tokens associated with that account.

The Fake Browser Update Scam Gets a Makeover

October 18, 2023

One of the oldest malware tricks in the book — hacked websites claiming visitors need to update their Web browser before they can view any content — has roared back to life in the past few months. New research shows the attackers behind one such scheme have developed an ingenious way of keeping their malware from being taken down by security experts or law enforcement: By hosting the malicious files on a decentralized, anonymous cryptocurrency blockchain.

an image of a warning that the Chrome browser needs to be updated, showing several devices (phone, monitor, etc.) open to Google and an enticing blue button to click in the middle.

In August 2023, security researcher Randy McEoin blogged about a scam he dubbed ClearFake, which uses hacked WordPress sites to serve visitors with a page that claims you need to update your browser before you can view the content.

The fake browser alerts are specific to the browser you’re using, so if you’re surfing the Web with Chrome, for example, you’ll get a Chrome update prompt. Those who are fooled into clicking the update button will have a malicious file dropped on their system that tries to install an information stealing trojan.

Earlier this month, researchers at the Tel Aviv-based security firm Guardio said they tracked an updated version of the ClearFake scam that included an important evolution. Previously, the group had stored its malicious update files on Cloudflare, Guardio said.

But when Cloudflare blocked those accounts the attackers began storing their malicious files as cryptocurrency transactions in the Binance Smart Chain (BSC), a technology designed to run decentralized apps and “smart contracts,” or coded agreements that execute actions automatically when certain conditions are met.

Nati Tal, head of security at Guardio Labs, the research unit at Guardio, said the malicious scripts stitched into hacked WordPress sites will create a new smart contract on the BSC Blockchain, starting with a unique, attacker-controlled blockchain address and a set of instructions that defines the contract’s functions and structure. When that contract is queried by a compromised website, it will return an obfuscated and malicious payload.

“These contracts offer innovative ways to build applications and processes,” Tal wrote along with his Guardio colleague Oleg Zaytsev. “Due to the publicly accessible and unchangeable nature of the blockchain, code can be hosted ‘on-chain’ without the ability for a takedown.”

Tal said hosting malicious files on the Binance Smart Chain is ideal for attackers because retrieving the malicious contract is a cost-free operation that was originally designed for the purpose of debugging contract execution issues without any real-world impact.

“So you get a free, untracked, and robust way to get your data (the malicious payload) without leaving traces,” Tal said. Continue reading

Tech CEO Sentenced to 5 Years in IP Address Scheme

October 17, 2023

Amir Golestan, the 40-year-old CEO of the Charleston, S.C. based technology company Micfo LLC, has been sentenced to five years in prison for wire fraud. Golestan’s sentencing comes nearly two years after he pleaded guilty to using an elaborate network of phony companies to secure more than 735,000 Internet Protocol (IP) addresses from the American Registry for Internet Numbers (ARIN), the nonprofit which oversees IP addresses assigned to entities in the U.S., Canada, and parts of the Caribbean.

Amir Golestan, the former CEO of Micfo.

In 2018, ARIN sued Golestan and Micfo, alleging they had obtained hundreds of thousands of IP addresses under false pretenses. ARIN and Micfo settled that dispute in arbitration, with Micfo returning most of the addresses that it hadn’t already sold.

ARIN’s civil case caught the attention of federal prosecutors in South Carolina, who in May 2019 filed criminal wire fraud charges against Golestan, alleging he’d orchestrated a network of shell companies and fake identities to prevent ARIN from knowing the addresses were all going to the same buyer.

Prosecutors showed that each of those shell companies involved the production of notarized affidavits in the names of people who didn’t exist. As a result, the government was able to charge Golestan with 20 counts of wire fraud — one for each payment made by the phony companies that bought the IP addresses from ARIN.

Golestan initially sought to fight those charges. But on just the second day of his trial in November 2021, Golestan changed his mind and pleaded guilty to 20 counts of wire fraud in connection with the phantom companies he used to secure the IP addresses. Prosecutors estimated those addresses were valued at between $10 million and $14 million. Continue reading

Patch Tuesday, October 2023 Edition

October 10, 2023

Microsoft today issued security updates for more than 100 newly-discovered vulnerabilities in its Windows operating system and related software, including four flaws that are already being exploited. In addition, Apple recently released emergency updates to quash a pair of zero-day bugs in iOS.

Apple last week shipped emergency updates in iOS 17.0.3 and iPadOS 17.0.3 in response to active attacks. The patch fixes CVE-2023-42724, which attackers have been using in targeted attacks to elevate their access on a local device.

Apple said it also patched CVE-2023-5217, which is not listed as a zero-day bug. However, as Bleeping Computer pointed out, this flaw is caused by a weakness in the open-source “libvpx” video codec library, which was previously patched as a zero-day flaw by Google in the Chrome browser and by Microsoft in Edge, Teams, and Skype products. For anyone keeping count, this is the 17th zero-day flaw that Apple has patched so far this year.

Fortunately, the zero-days affecting Microsoft customers this month are somewhat less severe than usual, with the exception of CVE-2023-44487. This weakness is not specific to Windows but instead exists within the HTTP/2 protocol used by the World Wide Web: Attackers have figured out how to use a feature of HTTP/2 to massively increase the size of distributed denial-of-service (DDoS) attacks, and these monster attacks reportedly have been going on for several weeks now.

Amazon, Cloudflare and Google all released advisories today about how they’re addressing CVE-2023-44487 in their cloud environments. Google’s Damian Menscher wrote on Twitter/X that the exploit — dubbed a “rapid reset attack” — works by sending a request and then immediately cancelling it (a feature of HTTP/2). “This lets attackers skip waiting for responses, resulting in a more efficient attack,” Menscher explained.

Natalie Silva, lead security engineer at Immersive Labs, said this flaw’s impact to enterprise customers could be significant, and lead to prolonged downtime.

“It is crucial for organizations to apply the latest patches and updates from their web server vendors to mitigate this vulnerability and protect against such attacks,” Silva said. In this month’s Patch Tuesday release by Microsoft, they have released both an update to this vulnerability, as well as a temporary workaround should you not be able to patch immediately.” Continue reading

Phishers Spoof USPS, 12 Other Natl’ Postal Services

October 9, 2023

The fake USPS phishing page.

Recent weeks have seen a sizable uptick in the number of phishing scams targeting U.S. Postal Service (USPS) customers. Here’s a look at an extensive SMS phishing operation that tries to steal personal and financial data by spoofing the USPS, as well as postal services in at least a dozen other countries.

KrebsOnSecurity recently heard from a reader who received an SMS purporting to have been sent by the USPS, saying there was a problem with a package destined for the reader’s address. Clicking the link in the text message brings one to the domain usps.informedtrck[.]com.

The landing page generated by the phishing link includes the USPS logo, and says “Your package is on hold for an invalid recipient address. Fill in the correct address info by the link.” Below that message is a “Click update” button that takes the visitor to a page that asks for more information.

The remaining buttons on the phishing page all link to the real USPS.com website. After collecting your address information, the fake USPS site goes on to request additional personal and financial data.

This phishing domain was recently registered and its WHOIS ownership records are basically nonexistent. However, we can find some compelling clues about the extent of this operation by loading the phishing page in Developer Tools, a set of debugging features built into Firefox, Chrome and Safari that allow one to closely inspect a webpage’s code and operations.

Check out the bottom portion of the screenshot below, and you’ll notice that this phishing site fails to load some external resources, including an image from a link called fly.linkcdn[.]to.

Click the image to enlarge.

A search on this domain at the always-useful URLscan.io shows that fly.linkcdn[.]to is tied to a slew of USPS-themed phishing domains. Here are just a few of those domains (links defanged to prevent accidental clicking):

usps.receivepost[.]com
usps.informedtrck[.]com
usps.trckspost[.]com
postreceive[.]com
usps.trckpackages[.]com
usps.infortrck[.]com
usps.quicktpos[.]com
usps.postreceive].]com
usps.revepost[.]com
trackingusps.infortrck[.]com
usps.receivepost[.]com
usps.trckmybusi[.]com

usps.stamppos[.]com
usps.stampspos[.]com
usps.trckmypost[.]com
usps.trckintern[.]com
usps.tackingpos[.]com
usps.posinformed[.]com

As we can see in the screenshot below, the developer tools console for informedtrck[.]com complains that the site is unable to load a Google Analytics code — UA-80133954-3 — which apparently was rejected for pointing to an invalid domain.

Notice the highlighted Google Analytics code exposed by a faulty Javascript element on the phishing website. Click to enlarge. That code actually belongs to the USPS.

The valid domain for that Google Analytics code is the official usps.com website. According to dnslytics.com, that same analytics code has shown up on at least six other nearly identical USPS phishing pages dating back nearly as many years, including onlineuspsexpress[.]com, which DomainTools.com says was registered way back in September 2018 to an individual in Nigeria.

A different domain with that same Google Analytics code that was registered in 2021 is peraltansepeda[.]com, which archive.org shows was running a similar set of phishing pages targeting USPS users. DomainTools.com indicates this website name was registered by phishers based in Indonesia.

DomainTools says the above-mentioned USPS phishing domain stamppos[.]com was registered in 2022 via Singapore-based Alibaba.com, but the registrant city and state listed for that domain says “Georgia, AL,” which is not a real location.

Alas, running a search for domains registered through Alibaba to anyone claiming to reside in Georgia, AL reveals nearly 300 recent postal phishing domains ending in “.top.” These domains are either administrative domains obscured by a password-protected login page, or are .top domains phishing customers of the USPS as well as postal services serving other countries.

Those other nations include the Australia Post, An Post (Ireland), Correos.es (Spain), the Costa Rican post, the Chilean Post, the Mexican Postal Service, Poste Italiane (Italy), PostNL (Netherlands), PostNord (Denmark, Norway and Sweden), and Posti (Finland). A complete list of these domains is available here (PDF). Continue reading

Don’t Let Zombie Zoom Links Drag You Down

October 2, 2023

Many organizations — including quite a few Fortune 500 firms — have exposed web links that allow anyone to initiate a Zoom video conference meeting as a valid employee. These company-specific Zoom links, which include a permanent user ID number and an embedded passcode, can work indefinitely and expose an organization’s employees, customers or partners to phishing and other social engineering attacks.

Image: @Pressmaster on Shutterstock.

At issue is the Zoom Personal Meeting ID (PMI), which is a permanent identification number linked to your Zoom account and serves as your personal meeting room available around the clock. The PMI portion forms part of each new meeting URL created by that account, such as:

zoom.us/j/5551112222

Zoom has an option to include an encrypted passcode within a meeting invite link, which simplifies the process for attendees by eliminating the need to manually enter the passcode. Following the previous example, such a link might look something like this:

zoom.us/j/5551112222/pwd=jdjsklskldklsdksdklsdkll

Using your PMI to set up new meetings is convenient, but of course convenience often comes at the expense of security. Because the PMI remains the same for all meetings, anyone with your PMI link can join any ongoing meeting unless you have locked the meeting or activated Zoom’s Waiting Room feature.

Including an encrypted passcode in the Zoom link definitely makes it easier for attendees to join, but it might open your meetings to unwanted intruders if not handled responsibly. Particularly if that Zoom link is somehow indexed by Google or some other search engine, which happens to be the case for thousands of organizations.

Armed with one of these links, an attacker can create meetings and invite others using the identity of the authorized employee. And many companies using Zoom have made it easy to find recently created meeting links that include encrypted passcodes, because they have dedicated subdomains at Zoom.us.

Using the same method, KrebsOnSecurity also found working Zoom meeting links for The National Football League (NFL), LinkedIn, Oracle, Humana, Disney, Warner Bros, and Uber. And that was from just a few minutes of searching. And to illustrate the persistence of some of these Zoom links, Archive.org says several of the links were first created as far back as 2020 and 2021.

KrebsOnSecurity received a tip about the Zoom exposures from Charan Akiri, a researcher and security engineer at Reddit. In April 2023, this site featured research by Akiri showing that many public Salesforce websites were leaking private data, including banks and healthcare organizations (Akiri said Salesforce also had these open Zoom meeting links before he notified them).

A Closer Look at the Snatch Data Ransom Group

September 30, 2023

Earlier this week, KrebsOnSecurity revealed that the darknet website for the Snatch ransomware group was leaking data about its users and the crime gang’s internal operations. Today, we’ll take a closer look at the history of Snatch, its alleged founder, and their claims that everyone has confused them with a different, older ransomware group by the same name.

According to a September 20, 2023 joint advisory from the FBI and the U.S. Cybersecurity and Infrastructure Security Administration (CISA), Snatch was originally named Team Truniger, based on the nickname of the group’s founder and organizer — Truniger.

The FBI/CISA report says Truniger previously operated as an affiliate of GandCrab, an early ransomware-as-a-service offering that closed up shop after several years and claims to have extorted more than $2 billion from victims. GandCrab dissolved in July 2019, and is thought to have become “REvil,” one of the most ruthless and rapacious Russian ransomware groups of all time.

The government says Snatch used a customized ransomware variant notable for rebooting Microsoft Windows devices into Safe Mode — enabling the ransomware to circumvent detection by antivirus or endpoint protection — and then encrypting files when few services are running.

“Snatch threat actors have been observed purchasing previously stolen data from other ransomware variants in an attempt to further exploit victims into paying a ransom to avoid having their data released on Snatch’s extortion blog,” the FBI/CISA alert reads. It continues:

“Prior to deploying the ransomware, Snatch threat actors were observed spending up to three months on a victim’s system. Within this timeframe, Snatch threat actors exploited the victim’s network moving laterally across the victim’s network with RDP for the largest possible deployment of ransomware and searching for files and folders for data exfiltration followed by file encryption.”

New York City-based cyber intelligence firm Flashpoint said the Snatch ransomware group was created in 2018, based on Truniger’s recruitment both on Russian language cybercrime forums and public Russian programming boards. Flashpoint said Truniger recruited “pen testers” for a new, then-unnamed cybercrime group, by posting their private Jabber instant messenger contact details on multiple Russian language coding forums, as well as on Facebook.

“The command requires Windows system administrators,” Truniger’s ads explained. “Experience in backup, increase privileges, mikicatz, network. Details after contacting on jabber: truniger@xmpp[.]jp.”

In at least some of those recruitment ads — like one in 2018 on the forum sysadmins[.]ru –the username promoting Truniger’s contact information was Semen7907. In April 2020, Truniger was banned from two of the top Russian cybercrime forums, where members from both forums confirmed that Semen7907 was one of Truniger’s known aliases.

[SIDE NOTE: Truniger was banned because he purchased credentials to a company from a network access broker on the dark web, and although he promised to share a certain percentage of whatever ransom amount Truniger’s group extracted from the victim, Truniger paid the access broker just a few hundred dollars off of a six-figure ransom].

‘Snatch’ Ransom Group Exposes Visitor IP Addresses

September 27, 2023

The victim shaming site operated by the Snatch ransomware group is leaking data about its true online location and internal operations, as well as the Internet addresses of its visitors, KrebsOnSecurity has found. The leaked data suggest that Snatch is one of several ransomware groups using paid ads on Google.com to trick people into installing malware disguised as popular free software, such as Microsoft Teams, Adobe Reader, Mozilla Thunderbird, and Discord.

First spotted in 2018, the Snatch ransomware group has published data stolen from hundreds of organizations that refused to pay a ransom demand. Snatch publishes its stolen data at a website on the open Internet, and that content is mirrored on the Snatch team’s darknet site, which is only reachable using the global anonymity network Tor.

The victim shaming website for the Snatch ransomware gang.

KrebsOnSecurity has learned that Snatch’s darknet site exposes its “server status” page, which includes information about the true Internet addresses of users accessing the website.

Refreshing this page every few seconds shows that the Snatch darknet site generates a decent amount of traffic, often attracting thousands of visitors each day. But by far the most frequent repeat visitors are coming from Internet addresses in Russia that either currently host Snatch’s clear web domain names or recently did.

The Snatch ransomware gang’s victim shaming site on the darknet is leaking data about its visitors. This “server status” page says that Snatch’s website is on Central European Summer Time (CEST) and is powered by OpenSSL/1.1.1f, which is no longer supported by security updates.

Probably the most active Internet address accessing Snatch’s darknet site is 193.108.114[.]41, which is a server in Yekaterinburg, Russia that hosts several Snatch domains, including snatchteam[.]top, sntech2ch[.]top, dwhyj2[.]top and sn76930193ch[.]top. It could well be that this Internet address is showing up frequently because Snatch’s clear-web site features a toggle button at the top that lets visitors switch over to accessing the site via Tor.

Another Internet address that showed up frequently in the Snatch server status page was 194.168.175[.]226, currently assigned to Matrix Telekom in Russia. According to DomainTools.com, this address also hosts or else recently hosted the usual coterie of Snatch domains, as well as quite a few domains phishing known brands such as Amazon and Cashapp.

The Moscow Internet address 80.66.64[.]15 accessed the Snatch darknet site all day long, and that address also housed the appropriate Snatch clear-web domains. More interestingly, that address is home to multiple recent domains that appear confusingly similar to known software companies, including libreoff1ce[.]com and www-discord[.]com.

This is interesting because the phishing domains associated with the Snatch ransomware gang were all registered to the same Russian name — Mihail Kolesnikov, a name that is somewhat synonymous with recent phishing domains tied to malicious Google ads.

Kolesnikov could be a nod to a Russian general made famous during Boris Yeltsin’s reign. Either way, it’s clearly a pseudonym, but there are some other commonalities among these domains that may provide insight into how Snatch and other ransomware groups are sourcing their victims.

DomainTools says there are more than 1,300 current and former domain names registered to Mihail Kolesnikov between 2013 and July 2023. About half of the domains appear to be older websites advertising female escort services in major cities around the United States (e.g. the now-defunct pittsburghcitygirls[.]com).

The other half of the Kolesnikov websites are far more recent phishing domains mostly ending in “.top” and “.app” that appear designed to mimic the domains of major software companies, including www-citrix[.]top, www-microsofteams[.]top, www-fortinet[.]top, ibreoffice[.]top, www-docker[.]top, www-basecamp[.]top, ccleaner-cdn[.]top, adobeusa[.]top, and www.real-vnc[.]top.

In August 2023, researchers with Trustwave Spiderlabs said they encountered domains registered to Mihail Kolesnikov being used to disseminate the Rilide information stealer trojan.

But it appears multiple crime groups may be using these domains to phish people and disseminate all kinds of information-stealing malware. In February 2023, Spamhaus warned of a huge surge in malicious ads that were hijacking search results in Google.com, and being used to distribute at least five different families of information stealing trojans, including AuroraStealer, IcedID/Bokbot, Meta Stealer, RedLine Stealer and Vidar.

LastPass: ‘Horse Gone Barn Bolted’ is Strong Password

September 22, 2023

The password manager service LastPass is now forcing some of its users to pick longer master passwords. LastPass says the changes are needed to ensure all customers are protected by their latest security improvements. But critics say the move is little more than a public relations stunt that will do nothing to help countless early adopters whose password vaults were exposed in a 2022 breach at LastPass.

LastPass sent this notification to users earlier this week.

LastPass told customers this week they would be forced to update their master password if it was less than 12 characters. LastPass officially instituted this change back in 2018, but some undisclosed number of the company’s earlier customers were never required to increase the length of their master passwords.

This is significant because in November 2022, LastPass disclosed a breach in which hackers stole password vaults containing both encrypted and plaintext data for more than 25 million users.

Since then, a steady trickle of six-figure cryptocurrency heists targeting security-conscious people throughout the tech industry has led some security experts to conclude that crooks likely have succeeded at cracking open some of the stolen LastPass vaults.

KrebsOnSecurity last month interviewed a victim who recently saw more than three million dollars worth of cryptocurrency siphoned from his account. That user signed up with LastPass nearly a decade ago, stored their cryptocurrency seed phrase there, and yet never changed his master password — which was just eight characters. Nor was he ever forced to improve his master password.

That story cited research from Adblock Plus creator Wladimir Palant, who said LastPass failed to upgrade many older, original customers to more secure encryption protections that were offered to newer customers over the years.

For example, another important default setting in LastPass is the number of “iterations,” or how many times your master password is run through the company’s encryption routines. The more iterations, the longer it takes an offline attacker to crack your master password.

Palant said that for many older LastPass users, the initial default setting for iterations was anywhere from “1” to “500.” By 2013, new LastPass customers were given 5,000 iterations by default. In February 2018, LastPass changed the default to 100,100 iterations. And very recently, it upped that again to 600,000. Still, Palant and others impacted by the 2022 breach at LastPass say their account security settings were never forcibly upgraded.

Palant called this latest action by LastPass a PR stunt.

“They sent this message to everyone, whether they have a weak master password or not – this way they can again blame the users for not respecting their policies,” Palant said. “But I just logged in with my weak password, and I am not forced to change it. Sending emails is cheap, but they once again didn’t implement any technical measures to enforce this policy change.”

Either way, Palant said, the changes won’t help people affected by the 2022 breach.

“These people need to change all their passwords, something that LastPass still won’t recommend,” Palant said. “But it will somewhat help with the breaches to come.”

LastPass CEO Karim Toubba said changing master password length (or even the master password itself) is not designed to address already stolen vaults that are offline.

“This is meant to better protect customers’ online vaults and encourage them to bring their accounts up to the 2018 LastPass standard default setting of a 12-character minimum (but could opt out from),” Toubba said in an emailed statement. “We know that some customers may have chosen convenience over security and utilized less complex master passwords despite encouragement to use our (or others) password generator to do otherwise.” Continue reading

Who’s Behind the 8Base Ransomware Website?

September 18, 2023

The victim shaming website operated by the cybercriminals behind 8Base — currently one of the more active ransomware groups — was until earlier today leaking quite a bit of information that the crime group probably did not intend to be made public. The leaked data suggests that at least some of website’s code was written by a 36-year-old programmer residing in the capital city of Moldova.

The 8Base ransomware group’s victim shaming website on the darknet.

8Base maintains a darknet website that is only reachable via Tor, a freely available global anonymity network. The site lists hundreds of victim organizations and companies — all allegedly hacking victims that refused to pay a ransom to keep their stolen data from being published.

The 8Base darknet site also has a built-in chat feature, presumably so that 8Base victims can communicate and negotiate with their extortionists. This chat feature, which runs on the Laravel web application framework, works fine as long as you are *sending* information to the site (i.e., by making a “POST” request).

However, if one were to try to fetch data from the same chat service (i.e., by making a “GET” request), the website until quite recently generated an extremely verbose error message:

The verbose error message when one tries to pull data from 8Base’s darknet site. Notice the link at the bottom of this image, which is generated when one hovers over the “View commit” message under the “Git” heading.

That error page revealed the true Internet address of the Tor hidden service that houses the 8Base website: 95.216.51[.]74, which according to DomainTools.com is a server in Finland that is tied to the Germany-based hosting giant Hetzner.

But that’s not the interesting part: Scrolling down the lengthy error message, we can see a link to a private Gitlab server called Jcube-group: gitlab[.]com/jcube-group/clients/apex/8base-v2. Digging further into this Gitlab account, we can find some curious data points available in the JCube Group’s public code repository.

For example, this “status.php” page, which was committed to JCube Group’s Gitlab repository roughly one month ago, includes code that makes several mentions of the term “KYC” (e.g. KYC_UNVERIFIED, KYC_VERIFIED, and KYC_PENDING).

This is curious because a FAQ on the 8Base darknet site includes a section on “special offers for journalists and reporters,” which says the crime group is open to interviews but that journalists will need to prove their identity before any interview can take place. The 8base FAQ refers to this vetting process as “KYC,” which typically stands for “Know Your Customer.”

“We highly respect the work of journalists and consider information to be our priority,” the 8Base FAQ reads. “We have a special program for journalists which includes sharing information a few hours or even days before it is officially published on our news website and Telegram channel: you would need to go through a KYC procedure to apply. Journalists and reporters can contact us via our PR Telegram channel with any questions.” Continue reading
