Akamai halts a record-breaking DDoS in Europe

Akamai says that it halted what would have been a record-breaking distributed denial of service (DDoS) attack in Europe.

Another month comes another report of a would-be record DDoS. Last month, Cloudflare detailed a record-breaking DDoS attack that it thwarted in June. This time, it’s the turn of Akamai.

According to Akamai, an undisclosed company was hit by sustained traffic over a 30-day period. That traffic peaked on 21st July when the company was hit with 659.6...

Mantis botnet responsible for record-breaking Cloudflare attacks

A botnet called Mantis has been linked to record-breaking attacks targeting Cloudflare customers.

Last month, Cloudflare said that it successfully mitigated a record-breaking DDoS attack of 26 million requests per second. Just a couple of months earlier, Cloudflare reported that it mitigated a previous record-breaking attack of 15.3 million requests per second.

Mantis has now been linked to both attacks.

For the attacks, the majority of traffic originated from...

Cloudflare mitigated a 15M requests-per-second DDoS

cloudflare cybersecurity cyber security ddos https

Cloudflare says that it successfully mitigated a huge 15.3 million requests-per-second DDoS attack.

The incident was the largest HTTPS attack that Cloudflare has seen. HTTPS attacks, Cloudflare notes, are “more expensive in terms of required computational resources because of the higher cost of establishing a secure TLS encrypted connection.”

Such attacks cost an attacker more to launch, and more for a victim to mitigate.

The target was a Cloudflare...

Five Eyes warn of Russian cyberattacks on critical infrastructure

A joint cybersecurity advisory issued by members of the Five Eyes alliance warns of increased attacks on critical infrastructure from Russia.

The Five Eyes alliance consists of the US, UK, Australia, Canada, and New Zealand. Members cooperate in signals intelligence.

Canadian academic Srdjan Vucetic believes the Five Eyes’ originated from Winston Churchill's Iron Curtain speech in 1946, in which the British PM warned of open conflict with the Soviet Union unless the...

DDoS attacks ‘became larger and more complex’ in 2021

Data collected by F5 suggests that Distributed Denial-of-Service (DDoS) attacks became “larger and more complex” last year.

While the prevalence of DDoS attacks decreased slightly over the previous year, the severity of each occurrence “ramped up markedly” in 2021.

By Q4 2021, the mean DDoS attack was in excess of 21Gbps. That’s more than four times larger than the beginning of 2020.

Not only did last year result in a larger overall mean attack size;...

China: Attacks from US IP addresses are using resources to target Russia

In a post on the CAC’s website, the agency wrote:

“Since late February, my country’s internet has been continuously attacked by overseas cyberattacks.

Overseas organizations controlled computers in China through attacks, and then carried out cyberattacks on Russia,...

Microsoft stopped a record 2.4 Tbps DDoS from around 70,000 devices

Microsoft swiftly put a stop to a record-breaking 2.4 Tbps DDoS attack that originated from around 70,000 compromised devices.

The DDoS targeted an unnamed Azure customer and would have been 140 percent higher than a 1 Tbps attack Microsoft stopped in 2020.

The latest attack would have even set a new record after surpassing a 2.3 Tbps attack that Amazon Web Services halted in February last year.

In a summary of DDoS attacks last year, Microsoft highlighted...

Nokia Deepfield finds most DDoS attacks originate from under 50 hosting companies

Research from the network intelligence experts at Nokia Deepfield has found that the majority of DDoS attacks originate from fewer than 50 hosting companies.

The researchers analysed a large sample of networks and traced the origins of most DDoS attacks (by frequency and traffic volume).

Nokia Deepfield undertook the research following its observation that DDoS traffic increased 40-50 percent following the implementation of COVID-19 lockdown measures. Since then, the...
