Spearphishing Attacks Against Hostmonster Customers

I tend to see a lot of phishing emails. The message I received this morning caught my eye. It was fairly well crafted and obviously targeted. After searching the Internet, I found that some GoDaddy customers have received something similar. This seems to be making its way around the internet to website administrators. The most curious thing to me is how someone associated the email address with a Hostmonster account.

As can be seen above, the message read–

Your account contains more than 4035 directories and may pose a potential performance risk to the server. Please reduce the number of directories for your account to prevent possible account deactivation.

In order to prevent your account from being locked out we recommend that you create special temp directory.

Carrier Grade NAT and the DoS Consequences

Republished from Corero DDoS Blog:

The Internet has a very long history of utilizing mechanisms that may breathe new life into older technologies, stretching it out so that newer technologies may be delayed or obviated altogether. IPv4 addressing, and the well known depletion associated with it, is one such area that has seen a plethora of mechanisms employed in order to give it more shelf life.

In the early 90s, the IETF gave us Classless Inter-Domain Routing (CIDR), which dramatically slowed the growth of global Internet routing tables and delayed the inevitable IPv4 address depletion. Later came DHCP, another protocol which assisted via the use of short term allocation of addresses which would be given back to the provider's pool after use. In 1996, the IETF was back at it again, creating RFC 1918 private addressing, so that networks could utilize private addresses that didn't come from the global pool. Utilizing private address space gave network operators a much larger pool to use internally than would otherwise have been available if utilizing globally assigned address space -- but if they wanted to connect to the global Internet, they needed something to translate those addresses. This is what necessitated the development of Network Address Translation (NAT).

SentinelOne adds feature to restore files hit by ransomware

SentinelOne has added a feature to its endpoint detection products that can restore files encrypted by cybercriminals, a common type of attack known as ransomware. The "rollback" feature will be available in the 1.6 versions of its Endpoint Protection Platform (EPP) and the Endpoint Detection and Response (EDR) products at no charge, said Dal Gemmell, director of product management. SentinelOne is among several vendors that are trying to displace traditional antivirus vendors with products that detect malware using deep analysis rather than signature-based detection. The company's products use a lightweight agent on endpoints such as laptops and desktops, which looks at the core of the operating system -- the kernel -- as well the the user space, trying to spot changes that might be linked to malware.To read this article in full or to leave a comment, please click here

In wake of Paris attacks, legislation aims to extend NSA program

A U.S. senator plans to introduce legislation that would delay the end of the bulk collection of phone metadata by the National Security Agency to Jan. 31, 2017, in the wake of security concerns after the terror attacks last Friday in Paris.Senator Tom Cotton, a Republican from Arkansas, believes that the termination of the program, scheduled for month-end under the USA Freedom Act,  "takes us from a constitutional, legal, and proven NSA collection architecture to an untested, hypothetical one that will be less effective."The transition will happen in less than two weeks, at a time when the threat level for the U.S. is "incredibly high," he said Tuesday.To read this article in full or to leave a comment, please click here

How Cisco is trying to keep NSA spies out of its gear

Cisco is working to build the confidence of prospective customers in its products, two years after disclosures of spying by the U.S. National Security Agency seeded doubt, particularly in China. It is increasingly putting more stringent security requirements on its suppliers and has launched a beta program that allows customers to analyze its products in a highly secure environment before buying. The efforts are intended to introduce more transparency to allay growing concerns over how supply chains could be opportunistically used by spies and cybercriminals. "I worry about manipulation, espionage and disruption," said Edna Conway, chief security officer of Cisco's global value chain, in a recent interview. "We worry about tainted solutions, counterfeit solutions and the misuse of intellectual property."To read this article in full or to leave a comment, please click here

Blackhole exploit kit makes a surprising encore appearance

The Blackhole exploit kit has made a surprising reappearance two years after cybercriminals stopped using it, according to security vendor Malwarebytes.Exploit kits are frameworks planted on Web pages that try to find software flaws on the computers in order to silently install malware.Blackhole was one of most popular exploit kits, but it faded from prominence after its alleged creator, who went by the nickname Paunch, was arrested in Russia. The kit was sold or rented to other cybercriminals in the underground economy for hacking tools.To read this article in full or to leave a comment, please click here

Hard-coded credentials make it simple to steal millions of sensitive records from apps

During a Black Hat Europe talk about (In)Security of Backend-as-a-Service, researchers warned that thousands of popular mobile apps have hard-coded backend credentials which could allow anyone to access millions of sensitive records. “Attacks are free, effortless, and simple,” they warned.Siegfried Rasthofer and Steven Arzt, PhD students at TU Darmstadt in Germany, focused on apps that use Backend-as-a-Service (BaaS) frameworks from the providers Amazon Web Services, CloudMine and Parse.com, which is owned by Facebook. This is the “first comprehensive security evaluation of several popular BaaS providers and APIs as well as their use in real-world Android and iOS applications.”To read this article in full or to leave a comment, please click here

Organizations sloppy about securing privileged accounts
