The following is our... Read more →

Cybersecurity Industry News Review – March 14, 2023

The U.K. Online Safety Bill triggers a security rebuke from WhatsApp, the Czech Republic concerned about TikTok, an international law enforcement effort shuts down the NetWire RAT infrastructure, while a study suggests workforce malaise towards reporting security incidents. By Joe Fay WhatsApp Would Leave U.K. Rather Than Break Encryption WhatsApp would pull its end-to-end encrypted messaging service in the U.K., rather than submit to any requirement to weaken its privacy stance to comply with the U.K. government’s Online Safety Bill. WhatsApp chief Will Cathcart said that 98 per cent of its users were outside the U.K., and ALL users wanted... Read more →

FBI: Cybercrime Shot Up in 2020 Amidst Pandemic

In 2020, as the world grappled with a fast-spreading global pandemic, the FBI received more than 2,000 complaints each day, totaling 791,790 for the year. This represents a 69% increase from the previous year and a total of U.S. $4.2 billion in losses, according to data collected by the FBI’s The Internet Complaint Center (IC3). Cybercriminals employed all manner of schemes to target businesses and individuals, including phishing, spoofing and tech support fraud, the FBI reported. The costliest cybercrimes were against businesses, involving Business E-mail Compromise (BEC) schemes that added up to U.S. $1.8 billion in losses from 19,369 reported... Read more →

Making Cyber Threats Big Data Manageable

By Adrian Winckles Director of Cyber Security, Networking and Big Data Research Group, Anglia Ruskin University Whilst figures differ depending on which report you read, Gartner estimates the average time between a breach and detection to be about 285 days. By this time, an attacker has long gone. With all the security products in an enterprise network today, why is this still so long? One reason maybe because threat detection is a big data problem. Particularly for network traffic based solutions. A handful of probes, or mirror ports, across a high-speed enterprise network and you could be capturing Terabytes of... Read more →

Calling All Cybersecurity Experts!

This year’s (ISC)² Security Congress – with the theme “Leaders of Tomorrow” – will take place September 25-27 in Austin, Texas at the JW Marriott. For the first time, Security Congress will be a stand-alone event, without former partner ASIS International. “We value the partnership we had with ASIS International for the past six years, but it was time for Security Congress to stand on its own to address the programming needs expressed by our members,” says (ISC)² CEO David Shearer. The cybersecurity conference will host more than 90 educational sessions, as well as a town hall meeting, career center... Read more →

Cyber Security Central

This blog entry focuses on introducing a new community focused resource designed to provide an avenue for the collaboration and sharing of information relating to Cyber Security. The Cyber Security Central website (www.cybersecuritycentral.com) seeks to extend the knowledge and best practices within the cyber security community. The overall goal of the site is to provide a platform to support the implementation of the National Cyber Security Strategy. Since the inception of the project a few months ago, I have tried to establish a site that seeks to demonstrate a broad view of the cyber security community from both the national... Read more →

Image forensics

An interesting analysis of a graphic recently used by Victoria's Secret in their advertising. This gives chapter and verse of the techniques used, and results obtained, demonstrating the ability to determine if an image has been altered, and even which parts of an image have been modified, and how. I find this particularly interesting because of the apparently widely held belief that steganography is "undetectable" without comparision to the original image. Most of the "Photoshop disasters" are glaringly obvious to the naked eye. As this demonstrates, analysis and detection of modification is easily accomplished, even when the differences are not...

Data sanitization

This article is originally from the IEEE Security and Privacy magazine, circa 2003. As such, some of the programs noted are out of date or obsolete. However, a number are still available and in use, and the basic concepts outlined are still valuable. Read more →

Should the CISSP CBK be improved to place greater emphasis on “human factors” in information security? Definitely Yes!

Should the CISSP CBK be expanded to cover "human factors" in security? [1] Add “Human Factors” No.[2] Clearly, human factors are a major component to information security and Gary Hinson presents effective arguments that they should be established as an additional domain. On the other hand, Rob Slade makes an effective argument that the human factors are a significant component of each of the current ten domains primarily based on his experience teaching the CBK® to CISSP® aspirants for (ISC)²®. In full disclosure, I also teach the CBK® to CISSP® aspirants, but not for (ISC)²®, but at a local college.... Read more →

TCP covert channel

Advertised as RSTEG (Retransmission STEGanography), the technique described in this paper actually uses the standard TCP operations to allow you to set up a kind of covert channel. Interesting idea, although likely neither terribly dangerous nor important. Read more →

Social network de-anonymizing

This paper, although rather abstract and academic, is a good survey of the research into social network data gathering, as well as a particular de-anonymizing attack. It points out the dangers of data aggregation that inherently exist in social networking. Read more →

Fast flux and related technologies

This paper provides an overview explanation of fast flux and double flux activities related to hiding malicious Websites, or avoiding takedown (particularly related to botnets). It also suggests certain actions which could mitigate such activity. The essay uses a lot of jargon and is not always clear, but does provide a decent basic explanation. Read more →
