The Akamai Security Intelligence Response Team (SIRT) has been monitoring activity surrounding CVE-2024-4577, a PHP vulnerability that affects installations running CGI mode that was disclosed in June 2024.
The vulnerability primarily affects Windows installations using Chinese and Japanese language locales, but it is possible that the vulnerability applies to a wider range of installations.
As early as one day after disclosure, the SIRT observed numerous exploit attempts to abuse this vulnerability, indicating high exploitability and quick adoption by threat actors.
The exploitations include command injection and multiple malware campaigns: Gh0st RAT, RedTail cryptominers, and XMRig.

In this blog post, we’ve included a comprehensive list of indicators of compromise (IOCs) for the various exploits we discuss.
Check Point Research recently discovered that threat actors have been using novel (or previously unknown) tricks to lure Windows users for remote code execution. Specifically, the attackers used special Windows Internet Shortcut files (.url extension name), which, when clicked, would call the retired Internet Explorer (IE) to visit the attacker-controlled URL. An additional trick on IE is used to hide the malicious .hta extension name. By opening the URL with IE instead of the modern and much more secure Chrome/Edge browser on Windows, the attacker gained significant advantages in exploiting the victim’s computer, although the computer is running the modern Windows 10/11 operating system.

Researchers from Avast have discovered a flaw in the cryptographic schema of the DoNex ransomware and its predecessors. In cooperation with law enforcement organizations, we have been silently providing the decryptor to DoNex ransomware victims since March 2024. The cryptographic weakness was made public at Recon 2024 and therefore we have no reason to keep […]
