Ransomware is shaking up the threat landscape as more organizations continue to fall victim to such attacks. However, there’s good news amid this rising threat. Avast has released free decryption keys to recover files encrypted by three ransomware strains - AtomSilo, Babuk, and LockFile. While the decryptor for AtomSilo and LockFile are the same, the decryption key for Babuk will work on files encrypted with .babuk or .babyk file extensions. 

In another news, Adobe released a patch for over 90 security vulnerabilities. These flaws can be abused to launch remote code execution attacks and create denial-of-service conditions.

However, on the not-so-bright-side, two malicious NPM packages were found delivering ransomware and password-stealing trojans to victims’ machines.

Top Breaches Reported in the Last 24 Hours

Cream Finance hit again
Decentralized Finance (DeFi) platform Cream Finance has been hacked again, allowing hackers to steal an estimated $130 million worth of cryptocurrency assets. The attack occurred after hackers found a vulnerability in the platform’s flash loaning system. This is the third time that the platform has been hacked this year. 

Private key leaked
The private key used to sign EU Digital Covid certificates has been reportedly leaked on online data breach marketplaces. Threat actors can get their hands on the private key and forge digital certificates or QR codes that may be then recognized as legitimate by the official government apps. 

Scoolio leaks data
Approximately 400,000 users of Scoolio had their information exposed due to an API flaw in the platform. The data exposed includes nicknames, parent email addresses, interests, UUID details, and personality traits of users.

Free decryption released
Avast has released free decryption utilities to recover files encrypted by three ransomware strains - AtomSilo, Babuk, and LockFile. The decryptors for AtomSilo and LockFile are the same because they share similarities. However, the decrypter will only work for past Babuk victims that had files encrypted with either the .babuk or .babyk file extensions only. 

Malicious NPM packages
Malicious NPM packages pretending to be Roblox libraries are found delivering ransomware and password-stealing trojans to unsuspecting users. The two packages are named noblox.js-proxy and noblox.js-proxies.
