Russian government hackers target Signal accounts in spyware campaign: researcher reveals how

Earlier this year, Donncha Ó Cearbhaill, a security researcher at Amnesty International, received a suspicious message on his Signal account. The message claimed to be from “Signal Security Support ChatBot” and warned of suspicious activity that could lead to a data leak. It demanded a verification code to prevent further access. Ó Cearbhaill, a veteran spyware investigator, instantly recognized this as a phishing attempt. But instead of ignoring it, he turned the tables and launched his own investigation into what turned out to be a widespread campaign by Russian government hackers targeting Signal accounts.

This is not just another phishing story. It is a case study in how state-backed actors exploit trust in encrypted messaging apps to steal sensitive information. Ó Cearbhaill shared his findings exclusively with TechCrunch, revealing the scale and sophistication of the operation. In this article, we break down how the attack worked, who was targeted, and what you can do to protect your Signal account.

How the phishing attack on Signal accounts worked

The hackers impersonated Signal’s official support team, sending messages that warned of fake security threats. The goal was simple: trick victims into entering a verification code that would link their Signal account to a device controlled by the attackers. This technique, known as “device linking,” allows hackers to read all messages and access contacts without needing to crack encryption.

Ó Cearbhaill noted that the attackers used a tool called “ApocalypseZ” to automate the process. This system enabled them to target thousands of users simultaneously with minimal human oversight. The interface and codebase were in Russian, which aligns with previous warnings from CISA, the UK’s National Cyber Security Centre, and Dutch intelligence, all of which attributed similar campaigns to Russian government hackers.

Who was targeted in this Russian hacking campaign?

Ó Cearbhaill discovered that he was one of more than 13,500 targets. The list included journalists he had worked with, as well as a colleague at Amnesty International. He believes the hackers used a “snowball hypothesis” — compromising one victim and then using their contact list to find new targets. “I am convinced I became a target because I was likely in a group chat with someone who got hacked,” he said.

German news magazine Der Spiegel reported that the same group compromised several high-profile politicians in Germany. This highlights the broad scope of the campaign, which targets not only security researchers but also journalists, activists, and political figures. The attackers translated victim chats into Russian, further confirming their state-sponsored nature.

How the researcher turned the tables on the attackers

Instead of panicking, Ó Cearbhaill used his expertise to trace the attack back to its source. He declined to reveal all his methods, fearing it would tip off the hackers. However, he shared that he identified the ApocalypseZ system and monitored the campaign in real time. “Having the attack land in my inbox was too good an opportunity to pass up,” he told TechCrunch.

He also warned that the attacks are ongoing, meaning the total number of targets is likely much higher than the 13,500 he observed earlier this year. He expects the hackers to avoid targeting him again, but he remains vigilant. “I welcome future messages, especially if they have zero-days they would like to share,” he joked, referring to unknown security flaws.

Protecting your Signal account from phishing attacks

If you are a Signal user, you can take immediate steps to defend against similar attacks. The most important measure is enabling Registration Lock. This feature requires a PIN to register your phone number on a new device, blocking hackers from hijacking your account even if they trick you into sharing a verification code.

Additionally, never share verification codes with anyone, even if they claim to be from Signal. The app’s official support team will never ask for such information. Always verify the sender’s identity before responding to security alerts. For more tips, check out our guide on how to secure your Signal account.

The bigger picture: Russian government hackers and encrypted apps

This campaign is part of a broader trend of state-backed actors targeting encrypted messaging platforms. Signal, known for its strong privacy protections, is a prime target because it is used by journalists, activists, and government officials. The Russian hacking group behind this attack has been linked to previous operations against Ukrainian military personnel and dissidents.

As Ó Cearbhaill’s investigation shows, even experienced security researchers can become targets. The key is to stay informed and use available security features. By enabling Registration Lock and remaining cautious of phishing attempts, you can significantly reduce your risk. For more on this, read our analysis of state-sponsored phishing campaigns.

In conclusion, the campaign against Signal users by Russian government hackers is a stark reminder that no app is immune to targeted attacks. However, with the right precautions, you can protect your account and your data. Stay alert, stay safe.

US Sanctions Target Cambodian Scam Network Leaders in Crackdown on Crypto Fraud and Human Trafficking

The United States has imposed sanctions on a Cambodian scam network accused of orchestrating large-scale cryptocurrency fraud and human trafficking. The Office of Foreign Assets Control (OFAC) recently named Senator Kok An among 29 individuals and organizations allegedly involved in schemes that defrauded American victims of millions of dollars.

These operations center on scam compounds across Cambodia, many embedded within casinos and commercial buildings. Victims are approached through social engineering tactics, including romance-based outreach and fraudulent investment offers, before being persuaded to transfer digital assets to platforms controlled by attackers.

How the Cambodian Scam Network Operates

Authorities say these campaigns rely on trust-building tactics that evolve over time. Once a relationship is established, victims are guided to fake investment platforms that mimic legitimate services, where deposited funds are quickly diverted. This Cambodian scam network has been linked to significant financial losses for American citizens.

US government estimates show that at least $10 billion was lost by Americans to scams based in Southeast Asia in 2024, marking a 66% year-over-year increase. Individual losses have in some cases reached millions of dollars. The scale of these operations highlights the growing threat of cyber-enabled fraud in the region.

Human Trafficking and Coercion

Beyond financial crime, the network is reportedly linked to widespread human trafficking. Individuals are often recruited with false job offers, only to be coerced into scam operations once inside these compounds. Victims have reported confiscated passports, physical abuse, and strict daily quotas for contacting targets.

Many facilities are tied to casino operations, which authorities say help process and obscure illicit financial flows. Kok An’s business interests, including hospitality and security services, are alleged to support these sites. Associated operators manage additional compounds where similar abuses have been reported, including unlawful detention and violence.

US Enforcement Actions Against the Network

The sanctions were coordinated with a broader law enforcement effort involving the Department of Justice (DoJ), the Federal Bureau of Investigation (FBI), and the US Secret Service (USSS). Recent actions tied to the investigation include seizure of 503 domains linked to fraudulent crypto platforms, disruption of a messaging app used to recruit trafficking victims, and criminal charges against operators in Burma and Cambodia.

These measures aim to disrupt the financial and operational infrastructure behind cyber-enabled fraud while addressing the misuse of digital assets in global crime networks. For more on related trends, read about the UK crackdown on Chinese crypto marketplace funding Southeast Asia scam hubs.

Impact of Sanctions on the Cambodian Scam Network

The sanctions block any US-based assets linked to the designated parties and prohibit transactions involving US persons. This effectively freezes the financial resources of the Cambodian scam network, making it harder for operators to move money or recruit new victims.

However, experts warn that these networks are adaptable. Many have already shifted operations to other countries in Southeast Asia, such as Myanmar and Laos, where enforcement is weaker. Building on this, international cooperation remains critical to dismantling these criminal enterprises.
