​The parents of a 19-year-old Connecticut honors student accused of taking part in a $243 million cryptocurrency heist in August were carjacked a week later, while out house-hunting in a brand new Lamborghini. Prosecutors say the couple was beaten and briefly kidnapped by six young men who traveled from Florida as part of a botched plan to hold the parents for ransom. 

The parents of a 19-year-old Connecticut honors student accused of taking part in a $243 million cryptocurrency heist in August were carjacked a week later — while out house-hunting in a brand new Lamborghini. Prosecutors say the couple was beaten and briefly kidnapped by six young men who traveled from Florida as part of a botched plan to hold the parents for ransom.

Late in the afternoon of Aug. 25, 2024 in Danbury, Ct., a married couple in their 50s pulled up to a gated community in a new Lamborghini Urus (investigators say the sports car still had temporary tags) when they were intentionally rear-ended by a Honda Civic.

A witness told police they saw three men exit a van that was following the Honda, and said the men began assaulting the couple and forcing them into the van. Local police officers spotted the van speeding from the scene and pursued it, only to find the vehicle crashed and abandoned a short distance away.

Inside the disabled van the police found the couple with their hands and feet bound in duct tape, the man visibly bruised after being assaulted with a baseball bat. Danbury police soon reported arresting six suspects in the kidnapping, all men aged 18-26 from Florida. They also recovered the abandoned Lamborghini from a wooded area.

A criminal complaint (PDF) filed on Sept. 24 against the six men does not name the victims, referring to them only as a married couple from Danbury with the initials R.C. and S.C. But prosecutors in Connecticut said they were targeted “because the co-conspirators believed the victims’ son had access to significant amounts of digital currency.”

What made the Miami men so convinced R.C. and S.C.’s son was loaded with cryptocurrency? Approximately one week earlier, on Aug. 19, a group of cybercriminals that allegedly included the couple’s son executed a sophisticated phone-based social engineering attack in which they stole $243 million worth of cryptocurrency from a victim in Washington, D.C.

That’s according to ZachXBT, a frequently cited crypto crime investigator who published a lengthy thread that broke down how the theft was carried out and ultimately exposed by the perpetrators themselves.

ZachXBT’s post included a screen recording of a Discord chat session made by one of the participants to the $243 million robbery, noting that two of the people involved managed to leak the username of the Microsoft Windows PCs they were using to participate in the chat.

One of the usernames leaked during the chat was Veer Chetal. According to ZachXBT, that name corresponds to a 19-year-old from Danbury who allegedly goes by the nickname “Wiz,” although in the leaked video footage he allegedly used the handle “Swag.”  Swag was reportedly involved in executing the early stages of the crypto heist — gaining access to the victim’s Gmail and iCloud accounts.

The same day ZachXBT published his findings, a criminal indictment was issued in Washington D.C. charging two of the men he named as involved in the heist. Prosecutors allege Malone “Greavys” Lam, 20, of Miami and Los Angeles, and Jeandiel “Box” Serrano, 21, of Los Angeles conspired to steal and launder over $230 million in cryptocurrency from a victim in Washington, D.C. The indictment alleges Lam and Serrano were helped by other unnamed co-conspirators.

“Lam and Serrano then allegedly spent the laundered cryptocurrency proceeds on international travel, nightclubs, luxury automobiles, watches, jewelry, designer handbags, and rental homes in Los Angeles and Miami,” reads a press release from the U.S. Department of Justice.

By tracing the flow of funds stolen in the heist, ZachXBT concluded that Wiz received a large percentage from the theft, noting that “additional comfort [in naming him as involved] was gained as throughout multiple recordings accomplices refer to him as ‘Veer’ on audio and in chats.”

“A cluster of [cryptocurrency] addresses tied to both Box/Wiz received $41M+ from two exchanges over the past few weeks primarily flowing to luxury goods brokers to purchase cars, watches, jewelry, and designer clothes,” ZachXBT wrote.

KrebsOnSecurity sought comment from Veer Chetal, and from his parents — Radhika Chetal and Suchil Chetal. This story will be updated in the event that anyone representing the Chetal family responds. Veer Chetal has not been publicly charged with any crime.

According to a news brief published by a private Catholic high school in Danbury that Veer Chetal attended, in 2022 he successfully completed Harvard’s Future Lawyers Program, a “unique pre-professional program where students, guided by qualified Harvard undergraduate instructors, learn how to read and build a case, how to write position papers, and how to navigate a path to law school.” A November 2022 story at patch.com quoted Veer Chetal (class of 2024) crediting the Harvard program with his decision to pursue a career in law.

It remains unclear which Chetal family member acquired the 2023 Lamborghini Urus, which has a starting price of around $233,000. Sushil Chetal’s LinkedIn profile says he is a vice president at the investment bank Morgan Stanley.

It is clear that other alleged co-conspirators to the $243 million heist displayed a conspicuous consumption of wealth following the date of the heist. ZachXBT’s post chronicled Malone’s flashy lifestyle, in which he allegedly used the stolen money to purchase more than 10 vehicles, rent palatial properties, travel with friends on chartered jets, and spend between $250,000 and $500,000 a night at clubs in Los Angeles and Miami.

WSVN-TV in Miami covered an FBI raid of a large rented waterfront home around the time Malone and Serrano were arrested. The news station interviewed a neighbor of the home’s occupants, who reported a recent large party at the residence wherein the street was lined with high-end luxury vehicles — all of them with temporary paper tags.

ZachXBT unearthed a video showing a person identified as Wiz at a Miami nightclub earlier this year, wherein they could be seen dancing to the crowd’s chants while holding an illuminated sign with the message, “I win it all.”

It appears that all of the suspects in the cyber heist (and at least some of the alleged carjackers) are members of The Com, an archipelago of crime-focused chat communities which collectively functions as a kind of distributed cybercriminal social network that facilitates instant collaboration.

As documented in last month’s deep dive on top Com members,  The Com is also a place where cybercriminals go to boast about their exploits and standing within the community, or to knock others down a peg or two. Prominent Com members are endlessly sniping over who pulled off the most impressive heists, or who has accumulated the biggest pile of stolen virtual currencies.

And as often as they extort and rob victims for financial gain, members of The Com are trying to wrest stolen money from their cybercriminal rivals — often in ways that spill over into physical violence in the real world.

One of the six Miami-area men arrested in the carjacking and extortion plot gone awry — Reynaldo “Rey” Diaz — was shot twice while parked in his bright yellow Corvette in Miami’s design district in 2022. In an interview with a local NBC television station, Diaz said he was probably targeted for the jewelry he was wearing, which he described as “pretty expensive.”

KrebsOnSecurity has learned Diaz also went by the alias “Pantic” on Telegram chat channels dedicated to stealing cryptocurrencies. Pantic was known for participating in several much smaller cyber heists in the past, and spending most of his cut on designer clothes and jewelry.

Earlier this year, Diaz was “doxed,” or publicly outed as Pantic, with his personal and family information posted on a harassment and extortion channel frequented by members of The Com. The reason cited for Pantic’s doxing was widely corroborated by multiple Com members: Pantic had inexplicably robbed two close friends at gunpoint, one of whom recently died of a drug overdose.

Government prosecutors say the brazen daylight carjacking was paid for and organized by 23-year-old Miami resident Angel “Chi Chi” Borrero. In 2022, Borrero was arrested in Miami for aggravated assault with a deadly weapon.

The six Miami men face charges including first-degree assault, kidnapping and reckless endangerment, and five of them are being held on a $1 million bond. One suspect is also charged with reckless driving, engaging police in pursuit and evading responsibility; his bond was set at $2 million. Lam and Serrano are each charged with conspiracy to commit wire fraud and conspiracy to launder money.

Cybercriminals hail from all walks of life and income levels, but some of the more accomplished cryptocurrency thieves also tend to be among the more privileged, and from relatively well-off families. In other words, these individuals aren’t stealing to put food on the table: They’re doing it so they can amass all the trappings of instant wealth, and so they can boast about their crimes to others on The Com.

There is also a penchant among this crowd to call attention to their activities in conspicuous ways that hasten their arrest and criminal charging. In many ways, the story arc of the young men allegedly involved in the $243 million heist tracks closely to that of Joel Ortiz, a valedictorian who was sentenced in 2019 to 10 years in prison for stealing more than $5 million in cryptocurrencies.

Ortiz famously posted videos of himself and co-conspirators chartering flights and partying it up at LA nightclubs, with scantily clad women waving giant placards bearing their “OG” usernames — highly-prized, single-letter social media accounts that they’d stolen or purchased stolen from others.

Ortiz earned the distinction of being the first person convicted of SIM-swapping, a crime that involves using mobile phone company insiders or compromised employee accounts to transfer a target’s phone number to a mobile device controlled by the attackers. From there, the attacker can intercept any password reset links, and any one-time passcodes sent via SMS or automated voice calls.

But as the mobile carriers seek to make their networks less hospitable to SIM-swappers, and as more financial platforms seek to harden user account security, today’s crypto thieves are finding they don’t need SIM-swaps to steal obscene amounts of cryptocurrency. Not when tricking people over the phone remains such an effective approach.

According to ZachXBT, the crooks responsible for the $243 million theft initially compromised the target’s personal accounts after calling them as Google Support and using a spoofed number. The attackers also spoofed a call from account support representatives at the cryptocurrency exchange Gemini, claiming the target’s account had been hacked.

From there the target was social engineered over the phone into resetting multi-factor authentication and sending Gemini funds to a compromised wallet. ZachXBT says the attackers also convinced the victim to use AnyDesk to share their screen, and in doing so the victim leaked their private keys.

 ​CISA has added three new vulnerabilities to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation.

CVE-2024-23113 Fortinet Multiple Products Format String Vulnerability
CVE-2024-9379 Ivanti Cloud Services Appliance (CSA) SQL Injection Vulnerability
CVE-2024-9380 Ivanti Cloud Services Appliance (CSA) OS Command Injection Vulnerability

These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise.
Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the Known Exploited Vulnerabilities Catalog as a living list of known Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise. BOD 22-01 requires Federal Civilian Executive Branch (FCEB) agencies to remediate identified vulnerabilities by the due date to protect FCEB networks against active threats. See the BOD 22-01 Fact Sheet for more information.
Although BOD 22-01 only applies to FCEB agencies, CISA strongly urges all organizations to reduce their exposure to cyberattacks by prioritizing timely remediation of Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.

​Microsoft today released security updates to fix at least 117 security holes in Windows computers and other software, including two vulnerabilities that are already seeing active attacks. Also, Adobe plugged 52 security holes across a range of products, and Apple has addressed a bug in its new macOS 15 “Sequoia” update that broke many cybersecurity tools. 

Microsoft today released security updates to fix at least 117 security holes in Windows computers and other software, including two vulnerabilities that are already seeing active attacks. Also, Adobe plugged 52 security holes across a range of products, and Apple has addressed a bug in its new macOS 15 “Sequoia” update that broke many cybersecurity tools.

One of the zero-day flaws — CVE-2024-43573 — stems from a security weakness in MSHTML, the proprietary engine of Microsoft’s Internet Explorer web browser. If that sounds familiar it’s because this is the fourth MSHTML vulnerability found to be exploited in the wild so far in 2024.

Nikolas Cemerikic, a cybersecurity engineer at Immersive Labs, said the vulnerability allows an attacker to trick users into viewing malicious web content, which could appear legitimate thanks to the way Windows handles certain web elements.

“Once a user is deceived into interacting with this content (typically through phishing attacks), the attacker can potentially gain unauthorized access to sensitive information or manipulate web-based services,” he said.

Cemerikic noted that while Internet Explorer is being retired on many platforms, its underlying MSHTML technology remains active and vulnerable.

“This creates a risk for employees using these older systems as part of their everyday work, especially if they are accessing sensitive data or performing financial transactions online,” he said.

Probably the more serious zero-day this month is CVE-2024-43572, a code execution bug in the Microsoft Management Console, a component of Windows that gives system administrators a way to configure and monitor the system.

Satnam Narang, senior staff research engineer at Tenable, observed that the patch for CVE-2024-43572 arrived a few months after researchers at Elastic Security Labs disclosed an attack technique called GrimResource that leveraged an old cross-site scripting (XSS) vulnerability combined with a specially crafted Microsoft Saved Console (MSC) file to gain code execution privileges.

“Although Microsoft patched a different MMC vulnerability in September (CVE-2024-38259) that was neither exploited in the wild nor publicly disclosed,” Narang said. “Since the discovery of CVE-2024-43572, Microsoft now prevents untrusted MSC files from being opened on a system.”

Microsoft also patched Office, Azure, .NET, OpenSSH for Windows; Power BI; Windows Hyper-V; Windows Mobile Broadband, and Visual Studio. As usual, the SANS Internet Storm Center has a list of all Microsoft patches released today, indexed by severity and exploitability.

Late last month, Apple rolled out macOS 15, an operating system update called Sequoia that broke the functionality of security tools made by a number of vendors, including CrowdStrike, SentinelOne and Microsoft. On Oct. 7, Apple pushed an update to Sequoia users that addresses these compatibility issues.

Finally, Adobe has released security updates to plug a total of 52 vulnerabilities in a range of software, including Adobe Substance 3D Painter, Commerce, Dimension, Animate, Lightroom, InCopy, InDesign, Substance 3D Stager, and Adobe FrameMaker.

Please consider backing up important data before applying any updates. Zero-days aside, there’s generally little harm in waiting a few days to apply any pending patches, because not infrequently a security update introduces stability or compatibility issues. AskWoody.com usually has the skinny on any problematic patches.

And as always, if you run into any glitches after installing patches, leave a note in the comments; chances are someone else is stuck with the same issue and may have even found a solution.
