UK research network Janet under ongoing and persistent DDoS attack

Attackers seem to be adjusting methods in response to Tweets


Publicly-funded academic computer network Janet has come under a persistent DDoS attack today, which hobbled multiple internet connections, including the Manchester to Manchester Core Router.

Janet, effectively the UK's computer network for educational and research institutions, first experienced connectivity problems shortly after 9am this morning.

Its engineers and security teams identified the cause as a DDoS attack and worked to identify the source of the assault and implement blocks.

After some suggestions of network stabilisation however, further problems were seen.

The network is funded by Jisc, formerly the Joint Information Systems Committee, a non-departmental public body in the UK, whose Major Incidents Twitter account provided the most recent updates:

At the time of writing the tactic is yet to have any great effect, with 35 connections down, according to Netsight. While mostly facility specific, the Manchester to Manchester Core Router backbone connection is also down.

Following our publication, Jisc send The Register a statement confirming that:

"On Monday 7 December at 9.24 a distributed denial-of-service (DDoS) attack caused unplanned disruption on the Janet network. This has resulted in a potentially intermittent service for all customers.

Our network and computer security incident response teams are currently working to resolve the problem.

Customers affected have been contacted and are being provided with up to date information."

So there we have it. ®

    26m requests a second? Not legit traffic, not even Bill Gates doing $1m giveaways could manage that

    Cloudflare said it this month staved off another record-breaking HTTPS-based distributed denial-of-service attack, this one significantly larger than the previous largest DDoS attack that occurred only two months ago.

    In April, the biz said it mitigated an HTTPS DDoS attack that reached a peak of 15.3 million requests-per-second (rps). The flood last week hit a peak of 26 million rps, with the target being the website of a company using Cloudflare's free plan, according to Omer Yoachimik, product manager at Cloudflare.

    Like the attack in April, the most recent one not only was unusual because of its size, but also because it involved using junk HTTPS requests to overwhelm a website, preventing it from servicing legit visitors and thus effectively falling off the 'net.

  • Man gets two years in prison for selling 200,000 DDoS hits
    Over 2,000 customers with malice on their minds

    A 33-year-old Illinois man has been sentenced to two years in prison for running websites that paying customers used to launch more than 200,000 distributed denial-of-services (DDoS) attacks.

    A US California Central District jury found the Prairie State's Matthew Gatrel guilty of one count each of conspiracy to commit wire fraud, unauthorized impairment of a protected computer and conspiracy to commit unauthorized impairment of a protected computer. He was initially charged in 2018 after the Feds shut down 15 websites offering DDoS for hire.

    Gatrel, was convicted of owning and operating two websites – DownThem.org and AmpNode.com – that sold DDoS attacks. The FBI said that DownThem sold subscriptions that allowed the more than 2,000 customers to run the attacks while AmpNode provided customers with the server hosting. AmpNode spoofed servers that could be pre-configured with DDoS attack scripts and attack amplifiers to launch simultaneous attacks on victims.

    A Malaysia-linked hacktivist group has attacked targets in India, seemingly in reprisal for a representative of the ruling Bharatiya Janata Party (BJP) making remarks felt to be insulting to the prophet Muhammad.

    The BJP has ties to the Hindu Nationalist movement that promotes the idea India should be an exclusively Hindu nation. During a late May debate about the status of a mosque in the Indian city of Varanasi – a holy city and pilgrimage site – BJP rep Nupur Sharma made inflammatory remarks about Islam that sparked controversy and violence in India.
