Squid is a caching proxy for the Web. Due to an Uncontrolled Recursion bug in versions 2.6 through 2.7.STABLE9, versions 3.1 through 5.9, and versions 6.0.1 through 6.5, Squid may be vulnerable to a Denial of Service attack against HTTP Request parsing. This problem allows a remote client to perform Denial of Service attack by sending a large X-Forwarded-For header when the follow_x_forwarded_for feature is configured. This bug is fixed by Squid version 6.6. In addition, patches addressing this problem for the stable releases can be found in Squid's patch archives.

On Dec. 18, 2013, KrebsOnSecurity broke the news that U.S. retail giant Target was battling a wide-ranging computer intrusion that compromised more than 40 million customer payment cards over the previous month.

Ten years later, KrebsOnSecurity has uncovered new clues about the real-life identity of Rescator.
