NEW: Google is rolling out a new feature for Android called Intrusion Logging, designed specifically to help researchers investigate attacks done with spyware and forensic tools. Amnesty says this is “a fundamental shift in the amount and quality of forensic data available on Android devices.”

Spyware forensic work has so far relied on incidental logs that were never designed for security analysis and are too often partial and short-lived. Now we have the possibility to detect advanced spyware, exploits and unauthorised physical access, even months after the fact.

Credit to the teams at Google and Android who engaged deeply on this work over the past two years, taking onboard a lot of feedback on what civil society forensic work needs. We hope this can be a starting point for more proactive efforts to support spyware accountability.

To help defenders and civil society leverage this tool to further accountability efforts we have released a forensic methodology guide. With colleagues at @rsf.org's Digital Security Lab we have built Intrusion Log support into the latest version of MVT and AndroidQF github.com/mvt-project/...

In January, a phishing message arrived on my Signal account, supposedly from "Signal Support." I was able to turned the tables on the attackers and get a unique view of the wide-scale campaign by the attacker's targeting journalists and politicians I was target #13,730 in their database.

Some in the German government have suggested moving away from Signal to other "secure" messengers. That's the wrong lesson. Signal's core security remains excellent. This would be like banning email just because some people got phished.

My recommendation for every Signal user: turn on Registration Lock to defend against this account-takeover technique. This is a clever campaign, but its reliance on social engineering reflects the strong core security of systems like Signal.

The tactics are consistent with what Google's Threat Intelligence Group has reported on UNC5792, a Russian state-aligned actor previously documented running Signal phishing operations against Ukrainian military and government users.

If the victim forwards that code back to "Support," the attackers gain access to the account and to all future messages, including group chats. In January the system was already at version v0.2.0.3, suggesting active, ongoing development.

The scale is far wider than Germany. The view I had into the attacks shows more than 13,700 Signal users had been targeted by January 2026, and the campaign has continued since. A small sample of targets includes senior politicians and journalists across Europe.

The automated system powering the campaign is named ApocalypseZ by its operators. Its codebase and operator interface are written exclusively in Russian. The attackers were also translating victim communications into Russian.

The attackers use the open-source signal-cli tool to control Signal accounts that send phishing messages in bulk. When a victim accepts the message request, the attackers attempt to re-register the target's Signal account, triggering Signal to send an SMS verification code to the target.

NEW: Staffers at notorious spyware maker Intellexa had live remote access to their customers' surveillance systems. This allowed them to see the personal data of targets hacked with Intellexa's spyware Predator, according to research based on a leaked training video. Needless to say, this is bad.

The level of remote access is more extensive and lax than previously thought. Intellexa staff simply logged in with TeamViewer (!) to a remote Predator customer system. The video shows staff could see live targeting and infection attempts from EAGLE_2, a customer in Kazakhstan.

The leaked materials also forensically confirm Predator’s use in previously documented attacks in Greece and Egypt - validating years of investigations by Amnesty, Citizen Lab & others.

Shockingly, the leaks shows that Intellexa kept REMOTE ACCESS to Predator systems deployed on government clients’ premises — meaning the company had the potential to see data about surveillance victims in real time..
