Cover: WhatsApp and Signal in hackers' crosshairs

This is one of the most serious cyber warnings in recent years: a Russian hacker group has specifically targeted accounts on the WhatsApp messenger and Signal, the app often considered a more secure alternative. High-ranking government officials, military personnel, and journalists in several European countries have been affected. For us here in Switzerland, where WhatsApp is practically a standard feature on every smartphone, the attack immediately raises questions: Just how vulnerable are we really? And what can we do to avoid becoming a target?

A new dimension in messenger attacks

The attacks, which I've been discussing with security experts over the last few hours, are more sophisticated than the usual phishing attempts. The hackers aren't sending simple spam messages; they're using perfectly disguised bait. Often, they'll pose as a contact from the victim's inner circle and send a link. Anyone clicking on it doesn't just land on a harmless website; instead, they open a backdoor through a vulnerability in WhatsApp Web or the mobile app. The really insidious part: the malware can then spread further through the chat list without the user realising it immediately.

Who's in the crosshairs – and what's that got to do with Switzerland?

According to information from security circles, the attacks are focusing on individuals with access to sensitive information. This includes employees at defence ministries, as well as investigative journalists. For Switzerland, home to numerous international organisations and a hub for diplomacy, this means heightened vigilance is needed. Although no official bodies here have been directly named yet, it would be naive to think Swiss users will be spared. The hackers' tactic is to compromise as many accounts as possible to get hold of internal correspondence.

From government to streamer: everyone's a potential target

It's interesting to note that this wave of attacks isn't just aimed at the elite. Even well-known personalities, like the German streamer Papaplatte with his huge community, could act as multipliers. If his WhatsApp account were to be hijacked, the hackers could trigger an avalanche through his contacts. It's a wake-up call for anyone who enjoys a certain level of public attention – and in today's connected world, that's a lot of people. The days of thinking "nobody's going to hack me" are well and truly over.

What does this mean for businesses and WhatsApp Business users?

The situation is particularly delicate for business customers using WhatsApp Business. It's not just about private chats here; it's about customer data, orders, and internal arrangements. A successful attack on a company account could have consequences that threaten its very existence. Hackers could pose as support staff and try to get hold of sensitive company information. That's why I strongly advise checking the security settings in the Business app and making employees aware of these new dangers.

How to protect yourself right now

There are a few simple but highly effective steps that every WhatsApp user in Switzerland should take immediately. Don't just rely on the default settings.

  • Switch on two-factor authentication: This is absolutely crucial. Go into Settings, then "Account" and "Two-step verification". Set up a PIN that only you know. This stops someone from cloning your SIM card and logging in as you.
  • Be careful with WhatsApp Web: Regularly check which devices have your WhatsApp open. In the app, under "Linked devices", you can see immediately if an unknown computer or browser has logged in. If so, log it out straight away!
  • A little suspicion is a good thing: Never click on links in messages that seem odd to you, even if they appear to be from a friend. If in doubt, give them a ring and ask if the message really came from them.
  • Keep your app up to date: Both WhatsApp and your operating system should always have the latest version. This is the quickest way to get security holes patched up.

Conclusion: The threat is real – and it's here to stay

This coordinated action against WhatsApp and Signal shows that messengers have long since become a battleground in cyber warfare. It's no longer about annoying adverts, but targeted espionage and sabotage. Especially for us in Switzerland, who are proud of our digital infrastructure, we need to do our homework. Look after yourselves – and your chats. The next phishing wave is guaranteed to come, but with the right awareness, we can make life difficult for the hackers.
