Foreign state hackers targeted WhatsApp and Signal accounts of senior EU officials through tricky spearphishing messages.
Foreign government hackers have attempted to break into the private chat accounts of high ranking European Union officials in a dangerous cyber espionage campaign.
Online attackers targeted popular messaging applications like Signal and WhatsApp, attempting to trick senior leaders into surrendering control of their phones.
By launching personalized trick messages directly to officials’ mobile devices, cybercriminals tried to gain access to confidential government conversations, private group chats, and sensitive policy discussions.
The illegal digital operation represents one of the most serious security threats facing European government networks this year.
The serious technology breach was formally highlighted in official cyber defense presentations delivered in Brussels on August 26, 2026.
An internal presentation prepared by the EU’s official cyber-defense team documented targeted account takeover attempts against political leaders, military officers, diplomats, and senior government staff across the region.
National intelligence agencies across Europe, including security authorities in Germany and the Netherlands, previously warned government workers about active digital attacks and directly linked some of the hacking operations to Russian state backed cyber groups.
The main reason state backed hackers targeted these popular chat platforms is that high level officials often use everyday phone apps to communicate quickly with team members.

Instead of breaking heavy encryption math directly, bad actors used a sneaky trick called spearphishing. Attackers sent direct messages pretending to be official customer support accounts, asking victims to enter verification PINs or scan fake QR codes.
If a user fell for the trick, the hackers could link their own laptop to the account and read incoming messages silently without raising immediate alarms.
Explaining how foreign governments are trying to trick senior leaders into giving away their phone access codes, EU security analysts noted in the internal presentation that officials faced “state sponsored spearphishing” operations using personalized messages crafted to compromise high ranking accounts.
Detailing why account takeovers represent such a dangerous threat to international security and government safety, German cyber defense authorities warned in a related security alert that “successful access to messenger accounts enables not only insight into confidential one on one communications but also the potential compromise of entire networks via group chats”.
Warning government workers that common phone applications require extra care and strict security checks, national intelligence researchers confirmed that ” attackers pose as official Signal support or security chatbots to persuade victims to share their security codes, allowing attackers to take control of the account”.
By identifying and stopping state backed hacking attempts, European security teams are acting quickly to protect government secrets.
Teaching public leaders how to spot fake support messages and enforcing strict two step verification rules ensures that private conversations remain safe from foreign spies and bad internet actors.
