Hackers in North Korea stole a total of $659 million in crypto across several heists in 2024, according to a joint statement issued today by the US, Japan, and South Korea. The report specified five such incidents, like the $235 million theft from the Indian crypto exchange WazirX that is being newly attributed to the Lazarus Group. That organization is estimated to have stolen billions across previous attacks over the last decade, including $625 million stolen from Axie Infinity in 2022.

As recently as September 2024, the United States government observed aggressive targeting of the cryptocurrency industry by the DPRK with well-disguised social engineering attacks that ultimately deploy malware, such as TraderTraitor, AppleJeus and others. The Republic of Korea and Japan have observed similar trends and tactics used by the DPRK.

A warning issued by the FBI last September noted that their methods to gain access for delivering these payloads include “individualized fake scenarios,” such as enticing victims with prospective jobs and business opportunities. All three countries advised businesses in the industry to check out the latest warning to reduce their risk of “inadvertently hiring DPRK IT workers,” as described in this recent report by CoinDesk.

They’ve also used long-time common phishing tactics against employees of crypto firms, such as convincing impersonations of trusted contacts or prominent people of interest in related industries, with realistic photos and information likely lifted from public social media accounts of known connections.

When we talk about data privacy, tech giants like Google and Facebook are often blamed for using personal data to show ads and recommendations. Less discussed are the businesses whose entire business model revolves around collecting your data and selling it to other companies and governments. These companies often operate in legal gray areas, with the consent required to collect user data buried deep in the fine print.

What’s even more concerning is that these data brokers fail to adequately protect the data they collect. Last year, National Public Data made headlines for failing to secure 2.7 billion records of individuals whose data it had harvested. Now, hackers have reportedly stolen data from Gravy Analytics, the parent company of Venntel, which has sold vast amounts of smartphone location data to the U.S. government.

What you need to know about the breach

Hackers claim to have breached Gravy Analytics, a major location data broker and parent company of Venntel, a firm known for selling smartphone location data to U.S. government agencies. The compromise is massive, including sensitive location data that tracks precise smartphone movements, customer information and even internal infrastructure, according to a 404 Media report.

The hackers are threatening to make the stolen data public. The files contain precise latitude and longitude coordinates of the phone and the time at which the phone was there. Some even indicate what country the data has been collected from.

Hackers have claimed access to Gravy’s systems since 2018. If true, this represents a serious security lapse on the company’s part. It is baffling how companies that collect and sell user data (a practice that arguably shouldn’t be allowed in the first place) failed to protect it from being leaked.

404 Media also suggests that the hackers gained deep access to the company’s infrastructure, including Amazon S3 buckets and server root access. The exposed customer list reportedly includes major companies like Uber, Apple and Equifax as well as government contractors like Babel Street.

What this breach means for people

This data breach highlights the serious security flaws in the location data industry. Companies like Gravy Analytics and Venntel have been profiting from collecting and selling sensitive location data, often without proper user consent. They’ve prioritized profit over security, and now the privacy of millions is at risk. This data could end up on black markets, endangering individuals, especially those in vulnerable situations, by making them targets for harassment or worse.

The FTC’s recent crackdown on Gravy, announced in December, underscores their negligence. The proposed order will prohibit these companies from selling or using location data, except in specific cases like national security or law enforcement. The implications are worrying. Sensitive locations like schools and workplaces could become easy targets for those with malicious intent.

5 ways to stay safe in the age of data breaches

The Gravy Analytics breach serves as a sobering reminder of the vulnerabilities in the digital age. While it’s impossible to control how every company handles data, you can take steps to minimize your exposure and protect your privacy. Here are five actionable tips to stay safe.

1) Limit app permissions: Many apps request access to location data, contacts and more, even when it’s not necessary for their functionality. Regularly review the permissions for apps on your smartphone and revoke access to anything that feels excessive. For instance, a weather app doesn’t need access to your microphone or camera.

2) Use a VPN: Virtual private networks (VPNs) can mask your IP address and encrypt your internet activity, making it harder for data brokers and hackers to track your online behavior. A good VPN adds an extra layer of security, especially when using public Wi-Fi networks. For the best VPN software, see my expert review of the best VPNs for browsing the web privately on your Windows, Mac, Android and iOS devices.

3) Opt out of data sharing where possible: Some companies allow you to opt out of having your data collected or shared. Services like Your Ad Choices and privacy settings within platforms like Google can help you reduce the amount of data collected. Check for opt-out options with any apps or services you use frequently.

4) Avoid free apps that monetize data: Free apps often generate revenue by selling user data. Instead, consider paid versions of apps that explicitly prioritize privacy. Research the company behind the app to understand its data handling policies before downloading.

5) Invest in data removal services: Data removal services can help you regain some control over your personal information by identifying and removing it from people-search websites, data broker platforms and other online databases. Check out my top picks for data removal services here.

WHAT TO DO IF YOUR BANK ACCOUNT IS HACKED

Kurt’s key takeaway

Companies that collect and sell user data pose a significant threat to privacy, and when they fail to protect this data, it often ends up in the hands of even worse actors. Cybercriminals, and even some governments, can exploit this information to target individuals. It is crucial to implement stringent repercussions for these companies when they fail in their duty to safeguard user data. A mere slap on the wrist is not enough. We need real accountability to deter negligence and protect individual privacy rights.
