Malware Takes Advantage of Windows "God Mode"

Microsoft Windows has hidden an Easter Egg since Windows Vista. It allows users to create a specially named folder that acts as a shortcut to Windows settings and special folders, such as control panels, My Computer, or the printers folder. This "God Mode" can come in handy for admins, but attackers are now using this undocumented feature for evil ends. Files placed within one of these master control panel shortcuts are not easily accessible via Windows Explorer because the folders do...

How broken is SHA-1 really?

SHA-1 collisions may be found in the next few months, but that doesnt mean that fake SHA-1-based certificates will be created in the near future. Nevertheless, it is time for everyone, and those working in security in particular, to move away from outdated hash functions.

DNS and DHCP Recon using Powershell, (Thu, Apr 28th)

I recently had a client pose an interesting problem. They wanted to move all their thin clients to a separate VLAN. In order to do that, I needed to identify which switch port each was on. Since there were several device vendors involved, I couldnt use OUI portion of the MAC. Fortunately, they were using only a few patterns in their thin client hostnames, so that gives me an in. Great you say, use nmap -sn, sweep for the names, get the MAC addresses and map those to switch ports - easy right?

Binary Webshell Through OPcache in PHP 7

In this article, we will be looking at a new exploitation technique using the default OPcache engine from PHP 7. Using this attack vector, we can bypass certain hardening techniques that disallow the file write access in the web directory. This could be used by an attacker to execute his own malicious code in a hardened environment.

sol52349521: OpenSSL vulnerability CVE-2016-2842

The doapr_outch function in crypto/bio/b_print.c in OpenSSL 1.0.1 before 1.0.1s and 1.0.2 before 1.0.2g does not verify that a certain memory allocation succeeds, which allows remote attackers to cause a denial of service (out-of-bounds write or memory consumption) or possibly have unspecified other impact via a long string, as demonstrated by a large amount of ASN.1 data, a different vulnerability than CVE-2016-0799. (CVE-2016-2842)
