Network Security: How Attackers Gain Access from Inside

Most people - mistakenly - believe that they are perfectly safe behind a firewall, network address translation (NAT) device or proxy. The fact is quite the opposite: if you can get out of your network, someone else can get in. Attackers often seek to compromise the weakest link in a network and then use that access to attack the network from the inside, commonly known as a "pivot-and-attack." more

DNS Attack Takes Down Internet in Five Northern and Coastal Provinces of China

According to Shanghai Daily, there has been an "organized Internet attack on Tuesday night which caused serious congestion in several provinces [in China] and left millions of users unable to gain access to the Internet." This is the first time the regulator has published news about an investigation into an online attack in China within 24 hours, says Shanghai Daily. ..."It was an attack on DNS (Domain Name System) and the carriers and related firms should do more back-up to avoid similar incidents," the ministry said in a statement. more

Encryption, Our Last Line of Defense

Encryption is fundamental to our daily life. Practically everything we do online makes use of encryption is some form. Access to our financial transactions, health records, government services, and exchanged private messages are all protected by strong encryption. Encryption is the process of changing the information in such a way as to make it unreadable by anyone except for those possessing special knowledge (usually referred to as a "key"), which allows them to change the information back to its original, readable form. more

Tackling Cyber Security: Should We Trust the Libertarians? Part 2

A couple of months ago, I wrote a post posing the question of whether or not more government regulation is required in order to secure the Internet. On the one hand, anonymity is viewed in the west as a forum for freedom of speech. The anonymity of the Internet allows dissidents to speak up against unpopular governments. However, the anonymity afforded by the Internet is not so much by design as it is byproduct of its original designers not seeing how widespread it would eventually become. more

Threat Intelligence in Latter 2019: Overcoming the Same and New Challenges

Does threat intelligence (TI) work? I looked into that question last year, exploring the reasons why it actually doesn't and what can be done to remediate the situation. Since then, more companies have incorporated TI into their security processes, and many are still not getting the benefits they expect. What's causing the dissatisfaction? Interestingly, pretty much the same aspects... more

Poland to Test a Cybersecurity Program for Aviation Sector

During the two-day Cybersecurity in Civil Aviation conference, Poland announced an agreement to test a cybersecurity pilot program for the aviation sector as Europe's European Aviation Safety Agency (EASA) civil aviation authority face increasing threats posed by hackers to air traffic. more

Pentagon Reveals Largest Ever Loss of Defense Data in Cyberattack

The Associated Press published an article today that the Pentagon revealed that earlier this year, they suffered one of its largest ever loss of sensitive data to a foreign government by a cyberattack. ... It's hard to say what's right and what's wrong. On the one hand, the Secretary of Defense says that the cyberwar is very real. On the other hand, the cyberczar Howard Schmidt said that there is no cyberwar and instead government needs to focus its efforts to fight online crime and espionage... more

Hacker Has Released Close to a Billion User Records Over the Past Two Months, Reports ZDNet

A hacker by the name of Gnosticplayers has claimed responsibility for the hacking of 44 companies resulting in over a billion user data. Hacker also gotten dangerously close to releasing the records, ZDNet reports. more

CNN.Com, Politically Motivated DDoS, and Asymmetric Warfare

Once again I find myself thinking about the nature of the asymmetric warfare threat posed by politically motivated DDoS (Estonia in 07, Korea in 02, and now China vs. CNN in 08). I keep thinking about it in terms of asymmetric warfare, a class of warfare where one side is a traditional, centrally managed military with superior uniformed numbers, weaponry, and skill. On the other we have smaller numbers, usually untrained fighters with meager weapons, and usually a smaller force. Historical examples include the North Vietnamese in the 20th century and even the American Revolution in the 18th century. Clearly this can be an effective strategy for a band of irregulars... more

U.S. Health Agency Suffers From Cyberattack, COVID-19 Disruptions by Foreign Actors Suspected

The U.S. Health and Human Services Department (HHS) is reported to have suffered from cyberattacks on its computer system believed, by those familiar with the incident, to be a disruption and disinformation campaign aimed at undermining the response to the coronavirus pandemic. more

Microsoft is Abandoning SHA-1 Hashes for Updates - But Why?

Microsoft is shipping a patch to eliminate SHA-1 hashes from its update process. There's nothing wrong with eliminating SHA-1 - but their reasoning may be very interesting. SHA-1 is a "cryptographic hash function". That is, it takes an input file of any size and outputs 20 bytes. An essential property of cryptographic hash functions is that in practice (though obviously not in theory), no two files should have the same hash value unless the files are identical. more

Can We Really Blame DNSSEC for Larger-Volume DDoS attacks?

In its security bulletin, Akamai's Security Intelligence Response Team (SIRT) reported on abuse of DNS Security Extensions (DNSSEC) when mounting a volumetric reflection-amplification attack. This is not news, but I'll use this opportunity to talk a bit about whether there is a trade-off between the increased security provided by DNSSEC and increased size of DNS responses that can be leveraged by the attackers. more

SEC Asks Companies to Disclose Cyberattacks

I came across an interesting article on Reuters today: "U.S. securities regulators formally asked public companies for the first time to disclose cyber attacks against them, following a rash of high-profile Internet crimes..." This is a pretty big step for the SEC. Requiring companies to disclose when they have been hacked shifts the action on corporations from something voluntary to something that they have to do. The question is do we want to hear about everything? more
