Politicians, Stop Exploiting Terror for Surveillance. It Won't Make Us More Secure.

Terror attacks are tragic. Terror attacks make each one of us long for security. That's why politicians repeatedly call for more surveillance after every terror attack. Most famously Theresa May, who wants to rip up human rights laws to fight terrorism. However, compelling data shows that more surveillance won't help at all: Every identified Islamist terrorist in Europe who killed innocent people with a terror attack since 2014 was already known to the authorities prior to the attack.

The WannaCry ransomware attack that affected more than 200.000 computers was also the fault of the NSA and Microsoft. While Microsoft is now offering a patch, the lesson we have to learn from this attack is that we need a different approach so secure the Internet: The open source approach.

Encryption solves a lot of challenges for Small and Medium-Sized Companies

The encrypted mail service Tutanota helps over two million users to share their mails securely - also with attachments. However, when the attachments get too large people and businesses need encrypted cloud storage as well. We've spoken to Istvan Lam, CEO of Tresorit, about our shared goal to make end-to-end encryption a tool to be used by the masses.

Email bomb hit Tutanota's contact email address with 500.000 newsletters

Two weeks ago a massive newsletter email bomb has been executed against Tutanota's main contact mailbox hello@tutao.de, which sent 500.000 newletters to this mailbox rendering it useless. The attacker has automatically signed up Tutanota's main email address to thousands of online newsletters so that confirmation request mails hit the hello-mailbox continuously. Until we implemented a protection method around half a million unwanted emails were received.

Hard Drive Issue Is Now Fixed.

On Friday we had to replace one broken hard drive. During this process mails that had already been deleted had been accidentally restored. This affected around 10.000 Tutanota users (around 0.5%), who were not able to access all mailbox folders (ie. inbox or drafts). We fixed this problem Saturday evening.

The Wolf That Guards the Door Or Why Privacy Matters

On April 3, 2017, President Trump signed a bill which was designed to cut out all of the FCCs protective laws for consumer internet use in the US. This action effectively opened the floodgates for advertisers and increased the reach of government procurement on data generated by private citizens.

American ISPs Can Sell Users' Internet History. Let's Buy Politicians Browsing History!

Only recently the American Senate passed S.J.Res 34, an anti-privacy law that allows American ISPs to sell their customers' internet history to the highest bidder. Now activism online against the bill is spreading like fire, one activist even started a fundraising campaign to buy politicians' browsing history. We think this idea is simply amazing and judging from a German example it might actually work.
