Security researchers are reporting a massive attack today, dubbed "WannaCry", which has reached 45,000 attacks in 74 countries around the world so far, mostly in Russia. more
Every year, Verisign iDefense Security Intelligence Services produces its Cyberthreats and Trends Report, which provides an overview of the key cybersecurity trends of the previous year and insight into how Verisign believes those trends will evolve. This report is designed to assist in informing cybersecurity and business operations teams of the critical cyberthreats and trends impacting their enterprises, helping them to anticipate key developments and more effectively triage attacks and allocate their limited resources. more
Neil Schwartzman writes to report: "Ken Magill covers the current rake fight on the IRTF's Anti-Spam Research Group mailing list concerning anti-spam DNS Blacklist, or Blocklist, (DNSBL) operators charging for delistings, that is well worth a read, he has quotes from many experts and leaders in the industry who are decidedly against the practice." more
Brian Krebs has a post up the other day on his blog indicating that the amount of spam ending in .cn has declined dramatically due to steps taken by the Chinese government making it more difficult to get a domain ending in .cn... A cursory glance seems to confirm that the amount of spam from .cn as opposed to .ru has switched places. Indeed, if the CNNIC requires people to start writing in application forms, with a business license and identity card, that is seriously going to slow down the rate at which spammers can sign up and register new domains. more
Previous posts (Part 1 and Part 2) offer background on DNS amplification attacks being observed around the world. These attacks continue to evolve. Early attacks focused on authoritative servers using "ANY" queries for domains that were well known to offer good amplification. Response Rate Limiting (RRL) was developed to respond to these early attacks. RRL, as the name suggests, is deployed on authoritative servers to rate limit responses to target names. more
When a business gets hacked and its corporate information is dumped on the Internet for all and sundry to see (albeit illegally), the effects of that breach are obviously devastating for all concerned. In many ways it's like the day after a fierce storm has driven a super-cargo container ship aground and beachcombers from far and wide have descended upon the ruptured carcass of metal to cart away anything they think has value or can be sold by the side of road. more
One of the longstanding goals of network security design is to be able to prove that a system -- any system -- is secure. Designers would like to be able to show that a system, properly implemented and operated, meets its objectives for confidentiality, integrity, availability and other attributes against the variety of threats the system may encounter. A half century into the computing revolution, this goal remains elusive. more
Last April, I shared information about a multistakeholder process that CIRA is part of, which seeks to identify and guide the development of policy around the Internet of Things (IoT), putting security at the heart of internet innovations in Canada. Since the formation of this process, we've made quite a bit of progress and I'm pleased to share some of that with you. more
The Australian has a good article describing the efforts some of their ISPs are making in an attempt to clean up their act: the government is encouraging ISPs to detect computers on their network that are infected and part of botnets, and to communicate to the customer that their system is compromised... Unless the customer feels a little bit of pain they will not change their ways. more
For a number of years, there have been many different high profile incidents where major websites were defaced, taken offline, or crippled due to issues related to their domain registration. Last night, there was an incident where several high profile domains went offline due to issues at their registrar, and they are now coming back online after what I am sure was a few crazy hours for their operations teams and management. more
Security experts and privacy advocates see the rollout of the new 5G wireless network as a possible solution to eliminate surveillance vulnerabilities that allow spying on nearby phone calls. more
Starting in mid-September, one of the largest and most sophisticated DDoS attacks ever targeted the titans of American banking. Initially, victims included Bank of America, JPMorgan Chase, Wells Fargo, PNC Bank, and U.S. Bancorp. In the weeks to come, others would also feel the pain. Websites crashed, customers were unable to make transactions and IT professionals and PR gurus went into panic mode. Leon Panetta, U.S. Secretary of Defense, said the attacks foreshadowed a "Cyber Pearl Harbor." more
Dennis Fisher of Thread Post reports: "The malware writers and criminals who run botnets for years have been using shared hosting platforms and so-called bulletproof hosting providers as bases of operations for their online crimes. But, as law enforcement agencies and security experts have moved to take these providers offline, the criminals have taken the next step and begun setting up their own virtual data centers." more
An article in Forbes the other day reports on US Secretary of Homeland Security Janet Napolitano's comments that 'cybercrime represents the "greatest threat and actual activity that we have seen aimed at the west and at the United States" in addition to "or other than Al Qaeda and Al Qaeda-related groups."' ..."Napolitano cited a study commissioned by Symantec that put the total worldwide cost of cybercrime at $388 billion -- higher than the global market for heroin, cocaine and marijuana combined." more
Canada's Communications Security Establishment (CSE) which rarely discloses detail of its activities has taken the "unprecedented step" of releasing one of its own cyber defense tools to the public, in a bid to help companies and organizations better defend their computers and networks against malicious threats. more
