Distributed denial-of-service (DDoS) attacks by pro-Russian hacking groups are causing alarm in the U.S. and Denmark after several incidents affected websites of hospitals and government offices in both countries. On Tuesday, Denmark announced that it was raising its cyber risk alert level after weeks of attacks on banks and the country’s defense ministry.

As part of our research into the cryptomining botnet kmsdbot, we rendered it useless.

Known as Operation Power Off, this operation saw law enforcement in the United States, the United Kingdom, the Netherlands, Poland and Germany take action against these types of attacks which can paralyse the internet.   The services seized were by far the most popular DDoS booter services on the market, receiving top billing on search engines. One such service taken...

FortiGuard Labs provides an analysis on RapperBot focusing on comparing samples for different campaigns, including one aiming to launch Distributed Denial of Service (DDoS) attacks. Read our blog to learn more about the differences observed in this campaign vs previous RapperBot and similar campaigns in the past.

Background On April 13, 2022, 360Netlab first disclosed the Fodcha botnet. After our article was published, Fodcha suffered a crackdown from the relevant authorities, and its authors quickly responded by leaving "Netlab pls leave me alone I surrender" in an updated sample.No surprise, Fodcha's authors didn't really stop updating after the fraudulent surrender, and soon a new version was released. In the new version, the authors of Fodcha redesigned the communication protocol and started to us

On June 27, 2022, Imperva mitigated a single attack with over 25.3 billion requests, setting a new record for Imperva’s application DDoS mitigation solution. While attacks with over one million requests per second (RPS) aren’t new, we’ve previously only seen them last for several seconds to a few minutes. On June 27, Imperva successfully mitigated a strong attack that lasted more than four hours and peaked at 3.9 million RPS.

We reveal how hackers have begun leveraging fake DDoS protection pages to trick users into downloading remote access trojans (RATs) onto their computers.

End of June 2021, Qrator Labs started to see signs of a new assaulting force on the Internet – a botnet of a new kind. That is a joint research we conducted together with Yandex to elaborate on the specifics of the DDoS attacks enabler emerging in almost real-time.

CHARGING MY LASER! Since the first quarter of 2022, there has been a significant increase in hacktivism worldwide.

A high-severity Palo Alto Networks denial-of-service (DoS) vulnerability has been exploited by miscreants looking to launch DDoS attacks, and several of the affected products won't have a patch until next week

The risk of distributed denial-of-service attacks (DDoS) has never been greater. Over the past several years, organizations have encountered a deluge of DDoS extortion, novel threats, state-sponsored hacktivism, and unprecedented innovation in the threat landscape.

Last week, Cloudflare automatically detected and mitigated a 26 million request per second DDoS attack — the largest HTTPS DDoS attack on record.

We recently began scanning for middlebox devices that are vulnerable to Middlebox TCP reflection, which can be abused for DDoS amplification attacks.  Our results are now shared daily, filtered for your network or constituency in the new Vulnerable DDoS Middlebox report. We uncover over 18,800,000 IPv4 addresses responding to our Middlebox probes. In some cases the amplification rates can exceed 10,000!

Against the backdrop of the conflict between Russia and Ukraine, the number of DDoS attacks in Q1 2022 increased by 4.5 times against Q1 2021. A significant proportion of them were by hacktivists.

Cyberattacks took down Finnish government websites on Friday while Ukrainian President Volodymyr Zelenskyy addressed Finland's members of parliament (MPs).

Geneva is a genetic algorithm that automatically learns how to evade nation state censors.

A new reflection/amplification distributed denial of service (DDoS) vector with a record-breaking potential amplification ratio of 4,294,967,296:1 has been abused by attackers in the wild to launch multiple high-impact DDoS attacks.

New method also stretches out DDoS durations to 14 hours.

Two cybersecurity firms with a strong business presence in Ukraine—ESET and Broadcom’s Symantec—have reported tonight that computer networks in the country have been hit with a new data-wiping attack. The attack is taking place as Russian military troops have crossed the border and invaded Ukraine’s territory in what Russian President Putin has described as a “peacekeeping” mission.

DDoS temporarily take out sites as Ukraine stares down Russian soldiers at its border.

What geopolitical standoff could this possibly be linked to?
