Hot Take on the Twitter Hack

If you read this blog, you've probably heard by now about the massive Twitter hack. Briefly, many high-profile accounts were taken over and used to tweet scam requests to send Bitcoins to a particular wallet, with the promise of double your money back. Because some of the parties hit are sophisticated and security-aware, it seems unlikely that the attack was a straightforward one directly on these accounts. more

Japan Developing Distinctive Anti-Cyberattack Virus

The Japanese Defense Ministry is creating a computer virus capable of tracking, identifying and disabling sources of cyberattacks, according to reports. The development of the virtual cyberweapon was launched in 2008. Since then, the weapon has been tested in a closed network environment. "The most distinctive feature of the new virus is its ability to trace cyber-attack sources. It can identify not only the immediate source of attack, but also all "springboard" computers used to transmit the virus." more

Blocking Amplification Attacks: Sometimes the Incentives Work Against You

Since the end of last year, amplification attacks have been increasingly used by attackers and received heavy media coverage. Everyday protocols not given much thought before, like Network Time Protocol (NTP), can be asked in a very short remote command to send a very large response (list of 600 clients last connected to the NTP server) to a spoofed IP address (the target) by the requestor/attacker. more

A Look at the Security Collapse in the HTTPS Market

While in recent years, HTTPS has become integral part of protecting social, political, and economic activities online, widely reported security incidents -- such as DigiNotar's breach, Apple's #gotofail, and OpenSSL's Heartbleed -- have exposed systemic security vulnerabilities of HTTPS to a global audience. more

What to Make of the Inaugural NetThing 2019

The last Australian Internet Governance Forum (auIGF) was held in October 2016 before the annual event was cancelled as part of an auDA review. Three years on and the auIGF replacement – NetThing – was held in Sydney on 28 October 2019, though I was surprised to see that this Australian Internet event no longer had an associated .au domain name, instead choosing to go with NetThing.info. more

According to the report, data will continue to be the primary motive behind future cyber crime-whether targeting traditional fixed computing or mobile applications. "It's all about the data," says security expert George Heron -- whether botnets, malware, blended threats, mobile threats or cyber warfare attacks. more

Is Anti-Virus Dead?

Each SANSFIRE, the Handlers who can make it to DC get together for a panel discussion on the state of information security. Besides discussion of the hot DNS issue, between most of us there is a large consensus into some of the biggest problems that we face. Two come to mind, the fact that "users will click anything" and that "anti-virus is no longer sufficient". These are actually both related in my mind... more

Characterizing the Friction and Incompatibility Between IoC and AI

Many organizations are struggling to overcome key conceptual differences between today's AI-powered threat detection systems and legacy signature detection systems. A key friction area -- in perception and delivery capability -- lies with the inertia of Indicator of Compromise (IoC) sharing; something that is increasingly incompatible with the machine learning approaches incorporated into the new breed of advanced detection products. more
