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
More than two months after authorities shut down a massive Internet traffic hijacking scheme, the malicious software that powered the criminal network is still running on computers at half of the Fortune 500 companies, and on PCs at nearly 50 percent of all federal government agencies, new research shows," reports Brian Krebs. more
According to multiple sources, Google this week reported that since early 2017, it has not had any of its 85,000 plus employees phished on their work accounts. more
According to the official news agency, Xinhua, implementation of China's controversial Cybersecurity Law will begin on June 1, requiring strict data surveillance and storage for companies operating in the county. more
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
China's home grown firms are not only grabbing domestic businesses but also venturing to different countries across the world. On the other hand, foreign players face regulatory walls that make it difficult to tap businesses in China." Saibal Dasgupta reporting today in VOA more
Trust is the lifeblood of the Internet and central to everything that is done here. In order for the current 3.5 billion users to continue using the Internet and its services, and for the next billion users to connect to the Internet, trust is required. The importance of trust is seen even more in Africa where, though there is a high growth of Internet users, the e-commerce uptake rate is very low. Users are very reluctant to carry out financial transactions over the Internet because of fear of being attacked by cybercriminals. more
In a 52 page security report released by Cisco, the company has confirmed what has been consistently been observed through out this year: "the Internet-based attacks are becoming increasingly sophisticated and specialized as profit-driven criminals continue to hone their approach to stealing data from businesses, employees and consumers." The 2008 edition of the report has specified the year's top security threats and offers recommendations for protecting networks against attacks that are propagating more rapidly, becoming increasingly difficult to detect, and exploiting technological and human vulnerabilities. more
Privacy problems are an area of wide concern for individual users of the Internet -- but what about network operators? Geoff Huston wrote an article earlier this year concerning privacy in DNS and the various attempts to make DNS private on the part of the IETF -- the result can be summarized with this long, but entertaining, quote. more
The RBNexploit blog states that the website 'president.gov.ge' was under DDoS attack since Thursday. That site is now hosted out of Atlanta, Georgia (don't you love coincidence?) by Tulip Systems who is prominently displaying an AP story... "Speaking via cell phone from Georgia, Doijashvili said the attacks, traced to Moscow and St. Petersburg, are continuing on the U.S. servers." Rusisan military surrogates in the form of the criminal Russian Business Network are engaged in attacks against servers on US soil. This point should be brought up as the Group of 8-1 discusses appropriate responses to Russia's attack on Georgia. more
Recently, there were news articles about a large software provider who experienced a global outage due to an expired digital certificate - and this is not the first time this kind of issue has hit the news. Digital certificate outages, when an organization forgets to replace an expiring certificate for a business-critical domain name, continues to cause business disruption and security risks. more
A new report warns that unless government and private sector decision makers begin developing specific procedures and trust now against cyber-enabled economic warfare (CEEW), the United States will find itself flat-footed during a major cyber event. more
A group of academic researchers have revealed a design weakness in the 4G/5G protocol which can be exploited by an attacker to identify the victim's presence in a particular cell area just from the victim's soft-identity such as phone number and Twitter handle. more
As noted in the first part of this series, Security and Reliability encompasses holistic network assessments, vulnerability assessments, and penetration testing. In this post I'd like to go deeper into network assessments. I stated last time that the phrase "network assessment" is broad. more
Two factor authentication that uses an uncopyable physical device (such as a cellphone or a security token) as a second factor mitigates most of these threats very effectively. Weaker two factor authentication using digital certificates is a little easier to misuse (as the user can share the certificate with others, or have it copied without them noticing) but still a lot better than a password. Security problems solved, then? more
