ASERT Security Intelligence

Summary: A 0day vulnerability in all supported versions of Microsoft Windows, CVE-2014-6352, is being used to compromise victims in targeted attack campaigns. A patch is not yet available, however workarounds exist. In other targeted attack news, threat actors are using the Sofacy/SEDNIT malware against highly sensitive targets. The Tactics, Techniques and Procedures (TTP's) of the attackers - dubbed "Operation Pawn Storm" by Trend - have been profiled and provide valuable insight that can be used to help protect organizations that fit the attack profile. Exploit code for a recently patched Adobe Flash vulnerability - CVE-2014-0569 - is now being used in at least two underground exploit kits, substantially increasing the threat surface for users that are not yet patched. In retail security news, Staples Inc. has launched an investigation into what appears to be a breach of customer credit and debit card data. Security industry analysts suspect Point of Sale malware may be involved.

IETF Discusses Deprecating IPv6 Fragments

The IETF IPv6 maintenance working group has begun discussions about deprecating IPv6 fragmented packets, spurred by the IETF Internet-Draft, “IPv6 Fragment Header Deprecated”. As one can guess, this draft has generated a lot of discussion (Although the Internet Draft discusses deprecation of the IPv6 fragment header, deprecation of the header would effectively deprecate IPv6 fragmented packets).

As I noted in an earlier posting here, fragments in IPv6 can create havoc in networks from an operational and a security perspective, [...]

DirtJumper’s DDoS Engine Gets a Tune-Up with new “Drive” Variant

Over the last few months ASERT has been tracking what appears to be a new variant in the DirtJumper family (for more information on the history of the DirtJumper family see our previous posts [ 1 ] [ 2 ] [ 3 ] ) – that we have dubbed “Drive.” Drive is written in Delphi and sports a new and much more powerful DDoS engine than its predecessors. It has also changed the format of attack commands [...]

The Revolution Will Be Written in Delphi

Since it has been a little while since we profiled a DDoS botnet family on the blog, let’s take a look at Trojan.BlackRev (also known as the “Black Revolution” trojan.) It was named for the Mutex set in early versions of the malware. This family is interesting from a research perspective because there are at least four revisions in the wild showing its progression from a basic DDoS bot to a more advanced one.
