IRS warns yet again on scam artist trickery

The IRS this week said some 4,000 victims have lost over $20 million to scammers and the rip-offs continue at a startling pace.+More on Network World: FBI and IRS warn of pervasive, maddening business, consumer scams+ The IRS noted what it called a number of new variations on old schemes: Scammers alter what appears on your telephone caller ID to make it seem like they are with the IRS or another agency such as the Department of Motor Vehicles. They use fake names, titles and badge numbers. They use online resources to get your name, address and other details about your life to make the call sound official. They even go as far as copying official IRS letterhead for use in email or regular mail. Brazen scammers will even provide their victims with directions to the nearest bank or business where the victim can obtain a means of payment such as a debit card. And in another new variation of these scams, con artists may then provide an actual IRS address where the victim can mail a receipt for the payment – all in an attempt to make the scheme look official. Scammers try to scare people Continue reading

Black Hat 2015: DHS deputy says ‘just trust us’

The deputy head of the Department of Homeland Security implored a group of skeptical security pros at Black Hat 2015 to share information about security incidents and to trust the government to keep it safe.“We understand the trust deficit that exists in the [security] community,” says Alejandro Mayorkas, deputy secretary of Homeland Security, encouraging attendees to participate in a government program where private businesses share information about cyber threats they encounter.+ MISS BLACK HAT? Get caught up with our stories from the show +Part of the trust problem is that businesses lack confidence that government can secure information it receives, Mayorkas says, citing the massive breach at the Office of Personnel Management. (It didn’t help his cause that as the meeting broke up news also broke that unclassified emails for the Joint Chiefs of Staff had been hacked and the email system shut down for two weeks.)To read this article in full or to leave a comment, please click here

Linux Core 6.3 as Network Host on VMware Disk

The Core Linux is a small modular Linux distribution that provides only a command line interface and tools that allows you to build your own application extensions. Thanks to these extensions you can easily turn your Core installation to a custom appliance such as network host, router, switch, server. Moreover choosing the Core Linux as an operating system for your appliance significantly reduces the size of the appliance.

Two weeks ago I started to build a network host that can handle network traffic. I installed the latest 64 bit Linux Core 6.3 on VMware virtual disk and loaded Core with extensions that can generate traffic, measure bandwidth, route, forward and filter traffic.  A list of the extensions, their purpose and configuration changes is mentioned here.

I share my own network host VMware disk in Linux Core download section. You can create a new virtual machine (VirtualBox, VMware Workstation/Player, Qemu) with the disk attached and use it in your GNS3 labs in order to simulate network host. The disk contains the following tcz extensions:

bash - 4.3.39(1) with patches up to 39
bash-completion - 2.1
d-itg - 2.8.1-r1023
hping3 - 3.0.0-alpha-1
iperf3 - 3.1b3
iproute2 - 3.14.0

Researchers find way to steal Windows Active Directory credentials from the Internet

An attack using the SMB file sharing protocol that has been believed to work only within local area networks for over a decade can also be executed over the Internet, two researchers showed at the Black Hat security conference.The attack, called an SMB relay, causes a Windows computer that’s part of an Active Directory domain to leak the user’s credentials to an attacker when visiting a Web page, reading an email in Outlook or opening a video in Windows Media Player.Those credentials can then be used by the attacker to authenticate as the user on any Windows servers where the user has an account, including those hosted in the cloud.In an Active Directory network, Windows computers automatically send their credentials when they want to access different types of services like remote file shares, Microsoft Exchange email servers or SharePoint enterprise collaboration tools. This is done using the NTLM version 2 (NTLMv2) authentication protocol and the credentials that get sent are the computer and user name in plain text and a cryptographic hash derived from the user’s password.To read this article in full or to leave a comment, please click here

Update Firefox now! Fix rushed out for an exploit that steals files off your hard drive

Late Thursday night, Mozilla released a security patch for the Firefox browser after finding a  serious vulnerability being exploited in the wild. The vulnerability allows malicious attackers to use some JavaScript magic to “search for and upload potentially sensitive” from your hard drive to their servers.Mozilla is asking all Firefox users to upgrade immediately to version 39.0.3. Anyone on the Firefox Extended Support release via their school or business should upgrade to version 38.1.1. MORE ON NETWORK WORLD: Free security tools you should try The security issue only affects PCs since the flaw relies on an interaction between Firefox’s PDF Viewer and other parts of the browser. Firefox for Android does not have the PDF Viewer and therefore not vulnerable, according to a blog post by Mozilla’s security lead, Daniel Veditz.To read this article in full or to leave a comment, please click here

Nest Cam review: a slightly pricey way to secure your home

They say an ounce of prevention is worth a pound of cure. With Nest’s motion-sensing camera, that prevention will put a dent in your wallet.The Google-owned company, which makes a smart thermostat and smoke detector, recently launched its first home security camera, the Nest Cam. It offers higher-quality video and smarter motion detection than its predecessor, the Dropcam, which Nest acquired last year. But with a bunch of similar cameras on the market, some of which come with cheaper or even free cloud storage plans, the Nest Cam is not necessarily a smart buy.To read this article in full or to leave a comment, please click here
