Over a year ago, Akamai’s threat research team published research regarding a widely-used phishing toolkit we referred to as the “Three Question Quiz”. It’s now time to review the evolution of the toolkit, the associated campaigns that we tracked in the wild, and the potential damage caused by those campaigns in the past year.

While we've highlighted both record PPS and BPS attacks mitigated on the Akamai Prolexic Platform over the past few weeks, these attacks are part of a broader trend of increasingly large and complex DDoS activity. We have seen clear indications across the industry of high-water mark DDoS attacks being publicized by multiple vendors. The sheer number of large attacks has been unprecedented. The attacks are also noteworthy for their increasing complexity, illustrated in the number and combinations of different attack vectors. The tenacity of attackers is also increasing -- one Akamai customer experienced 14 separate 100+ Gbps attacks in just the first half of 2020. "What's new is the concept of campaigns. We go back a couple of years, and 'attack' was the right word to use. There were many attacks every single day, but they weren't, in my opinion, campaign-oriented. Some of our more recent ones are campaign-oriented, where the attacker is working in a coordinated way over an extended period of time." -- Roger Barranco, Vice President, Global Security Operations, Akamai Some likely reasons for the rise in attacks are a combination of: The proliferation of DDoS-for-hire tools Emerging botnets (enterprise DVRs, IoT, etc.) entering the scene Plenty of motivating factors across social, geopolitical, and online unrest Quarantine and boredom -- what's a malicious actor supposed to do? Whatever the unique reason of each attack, the result is the same: a security and IT team needs an effective defense.

本文主要是通过ICSim(Instrument Cluster Simulator)模拟CAN协议通信，通过实践对CAN总线协议进行逆向分析。在实践过程中踩过一些坑，这里跟大家分享交流。

简介

CAN(Controller Area Network)总线是制造业和汽车产业中使用的一种简单协议，为ISO国际标准化的串行通信协议。在现代汽车中的小型嵌入式系统和ECU能够使用CAN协议进行通信，其通信是采用的广播机制，与TCP协议中的UDP差不多。各个系统或ECU（电子控制单元）都可以收发控制消息。1996年起该协议成了美国轿车和轻型卡车的标准协议之一，但是直到2008年才成为强制标准（2001年成为欧洲汽车标准）。当然1996年之前的也有可能使用CAN总线。现在，汽车的电子组件均通过CAN总线连接，针对汽车的攻击最终也都会通过CAN总线来实现。对于研究汽车安全，CAN总线协议是必须要掌握的。
