An analysis of benign internet scanner behavior across 24 new sensors in November 2024, examining discovery speed, port coverage, and vulnerability scanning capabilities of major services like ONYPHE, Censys, and ShadowServer. The study reveals most scanners found new assets within 5 minutes, with Censys leading in port coverage and ShadowServer in vulnerability detection.
Bulletproof hosting services provide the infrastructure for cybercriminal activities, enabling criminals to evade legal constraints and are often used for malware, hacking attacks, fraudulent…
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.

En début de semaine, un lien backbone qui véhicule Internet du nord au sud de la France a été tronçonné près d’Aix-en-Provence. Les conséquences sont mineures, mais interrogent sur la fragilité des infrastructures.
At most 15% of the approximately 820,000 PostgreSQL servers listening on the Internet require encryption. In fact, only 36% even support encryption. This puts PostgreSQL servers well behind the rest of the Internet in terms of security. In comparison, according to Google, over 96% of page loads in Chrome on a Mac are encrypted. The top 100 websites support encryption, and 97 of those default to encryption.
The way that many of our systems currently focus on engagement makes them particularly vulnerable to the incoming wave of content from bots like GPT-3
We recently began scanning for middlebox devices that are vulnerable to Middlebox TCP reflection, which can be abused for DDoS amplification attacks. Our results are now shared daily, filtered for your network or constituency in the new Vulnerable DDoS Middlebox report. We uncover over 18,800,000 IPv4 addresses responding to our Middlebox probes. In some cases the amplification rates can exceed 10,000!
We have recently began scanning for accessible MySQL server instances on port 3306/TCP. These are instances that respond to our MySQL connection request with a Server Greeting. Surprisingly to us, we found around 2.3M IPv4 addresses responding with such a greeting to our queries. Even more surprisingly, we found over 1.3M IPv6 devices responding as well (though mostly associated with a single AS). IPv4 and IPv6 scans together uncover 3.6M accessible MySQL servers worldwide.
