A Closer Look at the LAPSUS$ Data Extortion Group

Read Time:9 Minute, 47 Second

Microsoft and identity management platform Okta both this week disclosed breaches involving LAPSUS$, a relatively new cybercrime group that specializes in stealing data from big companies and threatening to publish it unless a ransom demand is paid. Here’s a closer look at LAPSUS$, and some of the low-tech but high-impact methods the group uses to gain access to targeted organizations.

First surfacing in December 2021 with an extortion demand on Brazil’s Ministry of Health, LAPSUS$ made headlines more recently for posting screenshots of internal tools tied to a number of major corporations, including NVIDIA, Samsung, and Vodafone.

On Tuesday, LAPSUS$ announced via its Telegram channel it was releasing source code stolen from Microsoft. In a blog post published Mar. 22, Microsoft said it interrupted the LAPSUS$ group’s source code download before it could finish, and that it was able to do so because LAPSUS$ publicly discussed their illicit access on their Telegram channel before the download could complete.

One of the LAPSUS$ group members admitted on their Telegram channel that the Microsoft source code download had been interrupted.

“This public disclosure escalated our action allowing our team to intervene and interrupt the actor mid-operation, limiting broader impact,” Microsoft wrote. “No customer code or data was involved in the observed activities. Our investigation has found a single account had been compromised, granting limited access. Microsoft does not rely on the secrecy of code as a security measure and viewing source code does not lead to elevation of risk.”

While it may be tempting to dismiss LAPSUS$ as an immature and fame-seeking group, their tactics should make anyone in charge of corporate security sit up and take notice. Microsoft says LAPSUS$ — which it boringly calls “DEV-0537” — mostly gains illicit access to targets via “social engineering.” This involves bribing or tricking employees at the target organization or at its myriad partners, such as customer support call centers and help desks.

“Microsoft found instances where the group successfully gained access to target organizations through recruited employees (or employees of their suppliers or business partners),” Microsoft wrote. The post continues:

“DEV-0537 advertised that they wanted to buy credentials for their targets to entice employees or contractors to take part in its operation. For a fee, the willing accomplice must provide their credentials and approve the MFA prompt or have the user install AnyDesk or other remote management software on a corporate workstation allowing the actor to take control of an authenticated system. Such a tactic was just one of the ways DEV-0537 took advantage of the security access and business relationships their target organizations have with their service providers and supply chains.”

The LAPSUS$ Telegram channel has grown to more than 45,000 subscribers, and Microsoft points to an ad that LAPSUS$ posted there offering to recruit insiders at major mobile phone providers, large software and gaming companies, hosting firms and call centers.

Sources tell KrebsOnSecurity that LAPSUS$ has been recruiting insiders via multiple social media platforms since at least November 2021. One of the core LAPSUS$ members who used the nicknames “Oklaqq” and “WhiteDoxbin” posted multiple recruitment messages to Reddit last year, offering employees at AT&T, T-Mobile and Verizon up to $20,000 a week to perform “inside jobs.”

LAPSUS$ leader Oklaqq a.k.a. “WhiteDoxbin” offering to pay $20,000 a week to corrupt employees at major mobile providers.

Many of LAPSUS$’s recruitment ads are written in both English and Portuguese. According to cyber intelligence firm Flashpoint, the bulk of the group’s victims (15 of them) have been in Latin America and Portugal.

“LAPSUS$ currently does not operate a clearnet or darknet leak site or traditional social media accounts—it operates solely via Telegram and email,” Flashpoint wrote in an analysis of the group. “LAPSUS$ appears to be highly sophisticated, carrying out increasingly high-profile data breaches. The group has claimed it is not state-sponsored. The individuals behind the group are likely experienced and have demonstrated in-depth technical knowledge and abilities.”

Microsoft said LAPSUS$ has been known to target the personal email accounts of employees at organizations they wish to hack, knowing that most employees these days use some sort of VPN to remotely access their employer’s network.

“In some cases, [LAPSUS$] first targeted and compromised an individual’s personal or private (non-work-related) accounts giving them access to then look for additional credentials that could be used to gain access to corporate systems,” Microsoft wrote. “Given that employees typically use these personal accounts or numbers as their second-factor authentication or password recovery, the group would often use this access to reset passwords and complete account recovery actions.”

In other cases, Microsoft said, LAPSUS$ has been seen calling a target organization’s help desk and attempting to convince support personnel to reset a privileged account’s credentials.

“The group used the previously gathered information (for example, profile pictures) and had a native-English-sounding caller speak with the help desk personnel to enhance their social engineering lure,” Microsoft explained. “Observed actions have included DEV-0537 answering common recovery prompts such as “first street you lived on” or “mother’s maiden name” to convince help desk personnel of authenticity. Since many organizations outsource their help desk support, this tactic attempts to exploit those supply chain relationships, especially where organizations give their help desk personnel the ability to elevate privileges.”

SIM-SWAPPING PAST SECURITY

Microsoft said LAPSUS$ also has used “SIM swapping” to gain access to key accounts at target organizations. In a fraudulent SIM swap, the attackers bribe or trick mobile company employees into transferring a target’s mobile phone number to their device. From there, the attackers can intercept any one-time passwords sent to the victim via SMS or phone call. They can also then reset the password for any online account that allows password resets via a link sent over SMS.

“Their tactics include phone-based social engineering; SIM-swapping to facilitate account takeover; accessing personal email accounts of employees at target organizations; paying employees, suppliers, or business partners of target organizations for access to credentials and multifactor authentication (MFA) approval; and intruding in the ongoing crisis-communication calls of their targets,” Microsoft wrote.

Allison Nixon is chief research officer at Unit 221B, a cybersecurity consultancy based in New York that closely tracks cybercriminals involved in SIM-swapping. Working with researchers at security firm Palo Alto Networks, Nixon has been tracking individual members of LAPSUS$ prior to their forming the group, and says the social engineering techniques adopted by the group have long been abused to target employees and contractors working for the major mobile phone companies.

“LAPSUS$ may be the first to make it extremely obvious to the rest of the world that there are a lot of soft targets that are not telcos,” Nixon said. “The world is full of targets that are not used to being targeted this way.”

Microsoft says LAPSUS$ also has been known to gain access to victim organizations by deploying the “Redline” password-stealing malware, searching public code repositories for exposed passwords, and purchasing credentials and session tokens from criminal forums.

That last bit is interesting because Nixon said it appears LAPSUS$ also was involved in the intrusion at game maker Electronic Arts (EA) last year, in which extortionists demanded $28 million in exchange for a promise not to publish 780 GB worth of source code. In an interview with Motherboard, the hackers claimed to have gained access to EA’s data after purchasing authentication cookies for an EA Slack channel from a dark web marketplace called Genesis.

“The hackers said they used the authentication cookies to mimic an already-logged-in EA employee’s account and access EA’s Slack channel and then trick an EA IT support staffer into granting them access to the company’s internal network,” wrote Catalin Cimpanu for The Record.

Why is Nixon convinced LAPSUS$ was behind the EA attack? The “WhiteDoxbin/Oklaqq” identity referenced in the first insider recruitment screenshot above appears to be the group’s leader, and it has used multiple nicknames across many Telegram channels. However, Telegram lumps all aliases for an account into the same Telegram ID number.

Back in May 2021, WhiteDoxbin’s Telegram ID was used to create an account on a Telegram-based service for launching distributed denial-of-service (DDoS) attacks, where they introduced themself as “@breachbase.” News of EA’s hack last year was first posted to the cybercriminal underground by the user “Breachbase” on the English-language hacker community RaidForums, which was recently seized by the FBI.

WHO IS LAPSUS$?

Nixon said WhiteDoxbin — LAPSUS$’s apparent ringleader — is the same individual who last year purchased the Doxbin, a long-running, text-based website where anyone can post the personal information of a target, or find personal data on hundreds of thousands who have already been “doxed.”

Apparently, Doxbin’s new owner failed to keep the site functioning smoothly, because top Doxbin members had no problems telling WhiteDoxbin how unhappy they were with his stewardship.

“He wasn’t a good administrator, and couldn’t keep the website running properly,” Nixon said. “The Doxbin community was pretty upset, so they started targeting him and harassing him.”

Nixon said that in January 2022, WhiteDoxbin reluctantly agreed to relinquish control over Doxbin, selling the forum back to its previous owner at a considerable loss. However, just before giving up the forum, WhiteDoxbin leaked the entire Doxbin data set (including private doxes that had remain unpublished on the site as drafts) to the public via Telegram.

The Doxbin community responded ferociously, posting on WhiteDoxbin perhaps the most thorough dox the community had ever produced, including videos supposedly shot at night outside his home in the United Kingdom.

According to the denizens of Doxbin, WhiteDoxbin started out in the business of buying and selling zero-day vulnerabilities, security flaws in popular software and hardware that even the makers of those products don’t yet know about.

“[He] slowly began making money to further expand his exploit collection,” reads his Doxbin entry. “After a few years his net worth accumulated to well over 300BTC (close to $14 mil).”

WhiteDoxbin’s Breachbase identity on RaidForums at one point in 2020 said they had a budget of $1 million in bitcoin with which to buy zero-day flaws in Github, Gitlab, Twitter, Snapchat, Cisco VPN, Pulse VPN and other remote access or collaboration tools.

“My budget is $100000 in BTC,” Breachbase told Raidforums in October 2020. “Person who directs me to someone will get $10000 BTC. Reply to thread if you know anyone or anywhere selling this stuff. NOTE: The 0day must have high/critical impact.”

KrebsOnSecurity is not publishing WhiteDoxbin’s alleged real name because he is a minor (currently aged 17), and because this person has not officially been accused of a crime. Also, the Doxbin entry for this individual includes personal information on his family members.

Nixon said that prior to launching LAPSUS$, WhiteDoxbin was a founding member of a cybercriminal group calling itself the “Recursion Team.” According to the group’s now-defunct website, they mostly specialized in SIM swapping targets of interest and participating in “swatting” attacks, wherein fake bomb threats, hostage situations and other violent scenarios are phoned in to police as part of a scheme to trick them into visiting potentially deadly force on a target’s address.

“The team is made up of Cyber-enthusiasts who major in skills including security penetration, software development, and botting,” reads the now-defunct Recursion Team website. “We plan to have a bright future, and we hope you do too!”

A Parent’s Guide to TikTok

Read Time:5 Minute, 59 Second

Finding someone who hasn’t heard of TikTok in 2022 would be quite the achievement. As one of the most popular social media platforms of the moment, it is not only being used by our tweens, teens and even grownups to connect but also as a crucial way to tell important stories amidst a backdrop of natural disasters and even war.  

As parents, we know we need to keep up with the latest social media platforms but let’s be real – we don’t always have enough time. So, I’m going to do the hard work for you. Here’s my overview of TikTok – what it is, the risks, and most importantly, how you can help your kids (or yourself) stay safe while using it. You’re welcome!! 

What Actually Is Tik Tok? 

Tik Tok is a social media platform that can be downloaded on any smartphone via an app. Once you’ve signed up to the app and become a user, you can create and then share short videos of 15 seconds in length on any topic. 

The app started life as Musical.ly, a super popular video streaming app that also allowed users to make funny 15-second videos, many of which focussed on lip-syncing. By mid-2017, the app had over 200 million registered users.  In 2018, the app was taken over by Chinese company ByteDance and all of its users (and their content) were moved to TikTok. 

How Popular is Tik Tok? 

According to Hootsuite, TikTok is the 6th most used social media platform in the world. As of late September 2021, TikTok had over a billion monthly users and as of August last year, it overtook Facebook to become the world’s most downloaded app. Facebook does, however, have more monthly users, reporting a massive 2.74 billion users as of August 2021 

Who Is Using It? 

It appears TikTok is used by females (57%) more than males (43%) however its user base is very diverse and cuts across all age categories – yes, even us parents! But brands hoping to reach younger female audiences are without a doubt using TikTok to showcase their wares. What is interesting is that although we all think that TikTok dominates the Gen Z market, research shows that it doesn’t rank as the top choice for younger users – in fact only 4.3% of users name it as their favorite platform. Users between 16 and 24 nominate Instagram as their top choice! 

How Old Do You Need To Be To Use TikTok? 

Unlike other social media platforms, there is no minimum age requirement when using TikTok. The company says that it adjusts a user’s privacy settings based on the birthday entered when setting up the account. If a user is under the age of 13, they will automatically be directed into the TikTok for Younger Users program which has additional privacy and safety protections. Of course, anyone can lie about their age, but TikTok has said publicly that it has moderators trained to predict when a user is suspected of being underage. 

What Are The Risks of Tiktok? 

As you would know, there are risks associated with using all social media platforms and TikTok is no exception. However, in my opinion the majority of these can be managed with a combination of critical thinking, parental controls, and preparation – more about these later.  

But let’s go worst-case scenario for one moment. Here are the potential risks that your child could encounter: 

Contact from online predators 
Inappropriate content: sexualized, violent, racist  
Potentially damaging conversations around mental health 
Anxiety from potentially poor reaction to their videos 

How To Manage The Risks On Tiktok? 

Unfortunately, it isn’t possible to keep our tweens and teens in a bubble – I know, so disappointing! So, the best and only option is to prepare them for challenges online and arm them with tools to navigate the tricky stuff. Here’s my advice on how to best help them manage TikTok:  

1. Download The App & Start a Conversation 

Knowledge is power, my friends. So, download the app and have a play so you better understand it. Then, why not ask your experienced in-house ‘TikTokers’ to show you how it works. Use this as an opportunity to ask them what they do when they see something that concerns them, or how they would manage approaches from people they don’t know. Why not weave in reminders about the importance of online privacy and the permanence of their digital footprint? Commit to making these conversations regular.  

2. Foster A Critical Thinking Mindset 

Helping your kids become critical thinkers is, without doubt, one of the best ways of helping them prepare for life’s challenges – both online and offline. Being able to rigorously question ideas and assumptions rather than accepting them at face value is your kids’ golden ticket! So, if they are approached by friendly (but ill-intentioned) strangers online or sent a link to a super compelling offer online, they will have the ‘smarts’ to realise that all is not as it seems and to hit delete! 

3. Use TikTok’s Parental Controls Or Help Them Set Up Privacy & Safety Settings  

If the horse has already bolted and your tween or teen has been using TikTok for a while, then introducing boundaries might be tricky but don’t give up! TikTok has a Family Pairing feature which allows parents to link their TikTok account to their teen’s account so they can control the settings remotely. This might be a good option if your child is younger or just starting out on TikTok. This gives parents the power to turn on Restricted Mode, screen time limits, and also turn off the direct message option.  

Leverage Tiktok’s Privacy Controls 

If your child has been using TikTok for some time and you want to pull things back, then why not work with them to set up their privacy and safety features. I find kids always respond best when you explain why you are doing something so assure them you are just wanting to keep them safe. TikTok has a long list of features you can enable that will make your offspring’s experience that much safer. From turning off downloads, filtering comments to introducing screen time limits, there is a great range of ways of making the TikTok experience much less risky. Check out the full list from TikTok here. 

So, next time you hear your kids reference TikTok, don’t immediately feel a pang of guilt that you don’t really know what they are talking about. You’ve got this! Download the app, take a look around, read this post a few more times, and you’ll be fine! And remember, our kids don’t expect us to be experts straight away, or even at all. They just need to know that we’re interested in all parts of their life and respect just how important their digital life is to them. 

You’ve got this!! 

Take care all
