Malware Increasingly Uses DNS As Command and Control Channel to Avoid Detection

Number of malware threats that receive instructions from attackers through DNS is expected to increase, and most companies are not currently scanning for such activity on their networks, security experts said at the RSA Conference 2012 on Tuesday. While most malware-generated traffic passing through most channels used for communicating with botnets (such as TCP, IRC, HTTP or Twitter feeds and Facebook walls) can be detected and blocked, it's not the case for DNS (Domain Name System) and attackers are taking advantage of that, said Ed Skoudis, founder of Counter Hack Challenges and SANS fellow. more

Most Cyberattacks Are From Hostile States, Reports U.K.‘s National Cyber Security Centre

The Networked Society and Personal Freedom

Given the current debate around mass surveillance which is undertaken by both governments and (social) media companies, the recurring question is what is happening to our hard-fought personal freedom? In the case of government-based mass surveillance there isn't an opt-out option, and in reality opt-out is also not a valid solution to services provided by Google, Apple, Facebook and the millions of apps that we all use to some extent or another. more

FBI vs Apple: A Bit Of Light Reading

Encryption is key to commerce online. Anything that weakens it is a threat to the digital economy, so the FBI vs Apple case is something that a lot of people are watching very closely... The most recent development is that Apple has filed "Motion to Vacate the Order Compelling Apple Inc. to Assist Agents in Search, and Opposition to the Government's Motion to Compel Assistance." Legal filings aren't light bedtime reading, but this one explores the legal issues as well as the privacy and security implications from multiple angles and underlines why this case is so important. more

Mega International DNS Malware Operation Dismantled, Reports FBI

FBI today announced six Estonian nationals have been arrested and charged with running a sophisticated Internet fraud ring that infected millions of computers worldwide with a virus and enabled the thieves to manipulate the multi-billion-dollar Internet advertising industry. Users of infected machines were unaware that their computers had been compromised -- or that the malicious software rendered their machines vulnerable to a host of other viruses. more

IoT Botnet Source Code Responsible for Historic Attack Has Been Publicly Released

The source code for the IoT botnet 'Mirai' has been released," warns security expert Brian Krebs whose own website was targeted with the same botnet resulting in the historically large DDoS attack last month. more

Incremental AI Risk: A Governance Lens for Digital Infrastructure and Public Policy

As artificial intelligence integrates into public infrastructure, it introduces new layers of systemic risk. Policymakers must shift focus from AI's potential to its exposure, applying governance models that reflect these emerging, compound vulnerabilities. more

Good Samaritans with Network Visibility

In a big open office 30 feet from me, a team of US Veterans speak intently on the phone to businesses large and small, issuing urgent warnings of specific cyber security threats. They call to get stubborn, confused people to take down hidden ransomware distribution sites. They call with bad news that a specific computer at the business has malware that steals login credentials. more

M3AAWG Offers Some Sensible Password Advice

M3AAWG is a trade association that brings together ISPs, hosting providers, bulk mailers, and a lot of infrastructure vendors to discuss messaging abuse, malware, and mobile abuse. (Those comprise the M3.) One of the things they do is publish best practice documents for network and mail operators, including two recently published, one on Password Recommendations for Account Providers, and another on Password Managers Usage Recommendations. more

What is a Security Mechanism?

Orin Kerr recently blogged about a 9th Circuit decision that held that scraping a public web site (probably) doesn't violate the Computer Fraud and Abuse Act (CFAA)... On its surface, it makes sense – you can't steal something that's public – but I think the simplicity of the rule is hiding some profound questions. One, I believe, can most easily be expressed as "what is the cost of the 'attack'"? That is, how much effort must someone expend to get the data? Does that matter? Should it? more

The FBI and the iPhone: Important Unanswered Questions

As you probably know, the FBI has gotten into Syed Farook's iPhone. Many people have asked the obvious questions: how did the FBI do it, will they tell Apple, did they find anything useful, etc.? I think there are deeper questions that really get to the full import of the break. How expensive is the attack? Security - and by extension, insecurity - are not absolutes. Rather, they're only meaningful concepts if they include some notion of the cost of an attack. more

Google Claims It Fixed the Security Holes the CIA Exploited

WikiLeaks shook the internet again on March 7, 2017, by posting several thousand documents containing information about the tools the CIA allegedly used to hack, among others, Android and iOS devices. These classified files were obtained from the CIA's Center for Cyber Intelligence, although they haven't yet been verified and a CIA official declined to comment on this incident. This isn't the first time that the U.S. government agencies were accused of crossing the line and undermining online security and civil liberties, as it's been only a year since the infamous FBI-Apple encryption dispute. It's like "1984" all over again. more

New Research Finds Over 80% of Domain Names Used by Phishers Are Legitimate Domains

New research from the Anti-Phishing Working Group (APWG) has found that up to 81% of domain names used for phishing are legitimate domains that have been hacked. More specifically, out of the 30,454 phishing domains under observation, only 5,591 domain names (18.5%) were registered by phishers according to APWG. The remaining small percentage of the domains used in phishing belonged to subdomain resellers such as ISPs and other web-based services. more
