Dutch Police discloses security breach after phishing attack

The Dutch National Police (Politie) says a security breach resulting from a successful phishing attack has had a limited impact and hasn't affected citizens' data.
It also stated that the incident is still under investigation by the agency's security experts and that the attackers' access to compromised systems has been blocked.
"The police have been the target of a phishing attack. The police's Security Operations Center detected the incident very quickly and immediately blocked access," the police said in a Wednesday press release.
"The impact is still being investigated but appears to be limited. Citizens' data and investigative information were not exposed or accessed. The police have also launched a criminal investigation."
The law enforcement agency has yet to disclose when the attack was detected and if any employees' data was exposed during the breach.
A Police spokesperson didn't immediately reply when BleepingComputer reached out for more information about the incident, including which systems or accounts were affected and whether any police officers had their data stolen, if any.
The Dutch police corps also disclosed a data breach in September 2024 following a cyberattack linked to a "state actor" that stole work-related contact information for multiple police officers, including their names, email addresses, phone numbers, and, in some cases, private data.
A follow-up investigation looking into the "nature, scope, and consequences of the data leak" is still ongoing, and the police have not publicly attributed the attack to a specific threat group or explained how it was carried out.
Following the attack, the police said they implemented stronger security measures to prevent future incidents, including continuously monitoring all systems for signs of suspicious activity and requiring officers to use two-factor authentication to log in to their accounts more frequently.
In February, Dutch authorities also arrested a 40-year-old man for an extortion attempt using confidential documents mistakenly shared by the Dutch police.

The Dutch National Police (Politie) has disclosed a recent security breach stemming from a phishing attack, though initial assessments indicate a limited impact on citizen data. According to a Wednesday press release, the Police’s Security Operations Center swiftly detected the attack and immediately blocked unauthorized access to compromised systems. The agency is currently conducting a comprehensive investigation into the incident’s scope and consequences. Despite the ongoing investigation, the Police stated that no citizens’ data or investigative information were exposed or accessed, and emphasized that a criminal investigation has been launched.

This incident follows a previous data breach in September 2024, attributed to a cyberattack linked to a “state actor.” This earlier attack resulted in the theft of contact information for numerous police officers, including names, email addresses, phone numbers, and, in some cases, private data. The investigation into this initial breach remains ongoing, and the Police have yet to explicitly identify the threat group involved or detail the precise methods employed in the attack.

In response to the current phishing attack, the Police have implemented strengthened security protocols, including continuous monitoring for suspicious activity and mandatory two-factor authentication for employee accounts. These measures aim to bolster defenses against future incidents. Furthermore, the Police’s response mirrors actions taken after a February incident involving the arrest of a 40-year-old man for extortion using mistakenly shared confidential documents.

Historically, the Dutch Police has faced cybersecurity challenges. A significant data leak in 2024, linked to a “state actor,” highlighted vulnerabilities and prompted a thorough examination of security practices. The ongoing investigation into both breaches underscores the importance of proactive security measures and continuous vigilance. The Police acknowledges the incident and continues to work diligently to understand and mitigate potential risks, while simultaneously pursuing legal action against those responsible.
