This Week in Security: Garmin Ransomware, KeePass , and Twitter Warnings

On July 23, multiple services related to Garmin were taken offline, including their call center and aviation related services. Thanks to information leaked by Garmin employees, we know that this multi-day outage was caused by the Wastedlocker ransomware campaign. After four days, Garmin was able to start the process of restoring the services.

It’s reported that the requested ransom was an eye-watering $10 million. It’s suspected that Garmin actually paid the ransom. A leaked decryptor program confirms that they received the decryption key. The attack was apparently very widespread through Garmin’s network, as it seems that both workstations and public facing servers were impacted. Let’s hope Garmin learned their lesson, and are shoring up their security practices.


KeePass released an update this week addressing a couple flaws in the KeePassRPC service. The update announcement is light on the details, but thankfully we have the full story directly from [Philipp Danzinger], the student that discovered the vulnerabilities. Both vulnerabilities are in the implementation of the SRP-6(a) key exchange protocol.

The vulnerable component is the RPC. KeyPass is essentially a simple database containing passwords. That database is encrypted using the user’s password, so the contained passwords cannot be retrieved without that master password. When a user launches KeePass, he or she is first prompted for this master password, and the database is decrypted using that password. The KeePassRPC service allows other processes, like a browser plugin, to access the now-decrypted database. The first time a new client attemps to access the RPC service, a keypair is generated, ..
