Following December 9th, 2021, the news of a Log4j Remote Code Execution (RCE) vulnerability began to grow (Figure 1). In addition to various malware families that already have utilized this vulnerability and added it to their delivery methods arsenal, more vulnerabilities related to this case were published, making Log4j, once simple Java-based logging utility, “the talk of the internet” these days.

On Dec. 9, 2021, a remote code execution (RCE) vulnerability in Apache log4j 2 was identified, (Dubbed “Log4Shell” by researchers), affecting massive amounts of servers all over the world. As this vulnerability gains high traction worldwide, it’s important to note, that not only internet facing java applications are vulnerable, as user input can traverse to another non-internet facing machines and exploit these as well.

True Login phishing kits are continuously being developed by threat actors to improve their TTPs in luring victims. By using true login kits, the phishing operators have a higher chance of making potential victims believe they are logging into the real website. True login kit developers are abusing publicly available APIs of the banking company to be able to query login information to be shown to potential victims, in turn luring the victim even further into the operations.

During the past month, the following notable high-severity vulnerabilities have been observed. It is recommended that those using affected products take immediate action to assess their exposure and patch and/or remediate as necessary.
