In this week’s round-up:

Security News

Ziggy Ransomware Releases Victim’s Decryption Keys

The administrator of the Ziggy ransomware has published a statement announcing that they are shutting down operations and publishing all decryption keys. In this announcement, the operator apologises for the harm they have caused their victims and says that the keys will be published as soon as possible. The administrator also revealed that they “created the ransomware to generate money as they live in a third-world country”; however, they felt too guilty to continue operations.

A SQL file containing 922 decryption keys was posted by the admin. Based on this information Emsisoft have made a decryptor available which can be found here.


Hacker Changes Chemical Levels of Drinking Water in Florida

The computer systems of Oldsmar, Florida’s water treatment facility were compromised last week and the chemical levels of the drinking water were changed. The hacker, who is yet to be identified, gained access to the facility from a remote computer set up for control of the water treatment operations. The attack was discovered almost immediately, and the changes were reverted; Oldsmar city staff have confirmed that no altered water was delivered to the locals. These kind of critical infrastructure attacks are what the cyber security community have been dreading, lets hope this does not become a more common occurrence.

GWENT Source Code Leaked in CD Projekt Red Ransomware Attack

CD Projekt Red, known for making games such as Cyberpunk 2077 and the Witcher, have become the latest victim of ransomware. Researchers have labelled this as a “double extortion ransomware”, as they expect another leak to be published soon. The firm have stated that they will not pay the ransom. The author of the leak has previously been seen on hacking forums associated with the Cobalt Strike malware, which explains his ability to perform the attack.

More updates will undoubtedly follow in the coming days.


Iran Hides Spyware in Phone Applications

Two groups of cybercriminals from Iran have been found running surveillance operations on users in Iran, the UK, US and 10 other countries. One of the groups is known as Domestic Kitten and has been observed fooling victims into downloading malicious applications that spy on the user’s activity on their mobile device. This campaign has had over 600 successful infections so far. We advise all users to only download applications from trusted app stores.
