Another day, another new list of security updates. Apple and Google have addressed almost 50 security flaws each as part of December 2019 Patch Tuesday. While Apple’s security updates address 50 vulnerabilities in macOS Catalina, iOS, iPadOS, Safari, and other software products, Google has released a stable version of Chrome 79 with a total of 51 security fixes.

A comeback of a massive cyberespionage campaign called Waterbear was also noticed in the past 24 hours. The campaign, which is believed to be backed by BlackTech threat actor group, has been evolved to include new obfuscation techniques. It uses two different APIs, namely ‘ZwOpenProcess’ and ‘GetExtendedTcpTable’ to hide its specific processes during the attack.

A new variant of Buran ransomware called Zeppelin has also been identified targeting IT and healthcare companies located in the U.S. and Europe. While encrypting target files, Zeppelin does not append an extension and the file name is also kept the same.

Top Breaches Reported in the Last 24 Hours

Over one billion credentials leaked

Top Malware Reported in the Last 24 Hours

Krampus-3PC
A new malware called Krampus-3PC has infected more than 100 publisher websites to target iPhone users. The users visiting any of the impacted sites are redirected to a fraudulent popup masquerading as a grocery store reward ad. Along the way, the malware proceeds to harvest users’ sessions and cookie information, thus giving attackers the ability to log into the victim’s various online accounts.

Zeppelin ransomware
Zeppelin is a new variant of VegaLocker/Buran ransomware. The ransomware has been spotted infecting the U.S and European IT and healthcare companies via targeted attacks. It is not known how the ransomware is being distributed, but it is likely through Remote Desktop servers that are publicly exposed to the internet.

Waterbear campaign
Waterbear campaign, which has been around for several years, is back with new evasion techniques. The campaign is associated with the cyberespionage group BlackTech, which mainly targets technology companies and government agencies in East Asia. In the recent Waterbear campaign, researchers have uncovered that the bad actors are using API hooking techniques to avoid being detected by a specific security product. The campaign uses two different APIs, namely ‘ZwOpenProcess’ and ‘GetExtendedTcpTable’ to hide its specific processes.
