| CVE-2021-44228 | JNDI Injection Remote Code Execution in Apache Log4j2 (Log4Shell) Apache Log4j2, an extremely widely used Java logging library, fails to protect its JNDI lookup feature against attacker-controlled JNDI-related endpoints (CWE-20, CWE-502), so crafted text processed by the logger causes the Java runtime to fetch and load attacker-supplied objects, leading to remote code execution. The flaw is triggered whenever attacker-controlled input reaches the logging API and is parsed for JNDI lookups, a pattern common in web servers and enterprise Java applications that log user-supplied fields such as headers or form values. Successful exploitation yields arbitrary code execution under the privileges of the affected application, giving attackers a foothold for lateral movement, data theft, and ransomware deployment. Any Java application or product that ships or bundles an affected Apache Log4j2 release is exposed, making this one of the most broadly deployed vulnerabilities ever disclosed. Exploitation is confirmed in the wild: CISA added it to the Known Exploited Vulnerabilities catalog on 2021-12-10 with known ransomware use, and EPSS assigns a 100% probability of exploitation within 30 days. Do: Inventory all Java applications and dependencies for Apache Log4j2 and apply the vendor's patched updates, or remove affected assets from the network, as required by CISA's KEV catalog. Where updates are not yet available, use the temporary mitigations in CISA's ED-22-02 recommended-mitigation guidance, such as disabling message lookups, only until patches are applied. Prioritize internet-facing and business-critical systems and hunt for exploitation activity given known ransomware use. | 10.0 | 100% | KEV ransomware PoC ×9 |

The Emotet malware has continued to climb the rankings of Check Point’s Most Wanted Malware List in March thanks to a new campaign relying on spam emails containing a malicious OneNote file.
The threat is now second on the list, one spot up from February’s report. The campaign responsible for its growth in adoption lures victims to open a malicious OneNote file that installs the malware.
Once installed, Emotet can gather login credentials and contact information to expand the campaign’s reach and facilitate future attacks. The new technique, according to the Check Point report, is a result of Microsoft announcing blocking macros from Office files.

“We know that Emotet is a sophisticated Trojan, and it is no surprise to see it has managed to navigate Microsoft’s latest defenses,” explained Maya Horowitz, VP of research at Check Point Software.
“The most important thing people can do is make sure they have appropriate email security in place, avoid downloading any unexpected files and adopt healthy skepticism about the origins of an email and its contents.”
As for the rest of the malware in Check Point’s latest Most Wanted report, the Qbot banking trojan has retained its top spot. At the same time, the Formbook infostealer is now in third position after being overtaken by Emotet.
In the mobile landscape, the AhMyth RAT was the most wanted malware in March, replacing the Anubis banking Trojan, which is now in second position. Hiddad is third, down one spot from February.
The top exploited vulnerability in March was a remote code execution vulnerability in Apache Log4j (CVE-2021-44228). The second spot was taken by various HTTP headers remote code execution (RCE) flaws (CVE-2020-10826, CVE-2020-10827, CVE-2020-10828, CVE-2020-13756) and the third one by an RCE in MVPower DVR devices.
The list also includes the top-attacked industries globally.
