The Case of Simultaneous, Short Duration DDoS Attacks

Over the last decade, DDoS attacks have proliferated, possibly becoming the primary threat for every website or web application.
The ultimate goal is to bring down sites by flooding them with fake requests, usually from multiple locations. The outcome of such attacks ranges from slow page loads to blocking legitimate traffic.
Among the thousands of DDoS attacks that happen every day, you’ll find attacks that last a number of days, as opposed to short-duration attacks that only take a few minutes for attackers to coordinate and launch at a time.
These attacks are becoming much more commonplace, whether the goal is to take a site down or if they’re used as a smokescreen to divert site owners’ attention.
In this article, I would like to share our real life experience with short-duration DDoS attacks, addressing what happens when this type of attack targets multiple sites simultaneously.
5 Short Attacks in 3 Days
We recently witnessed a three day, continuous attack that targeted two domains of a well-known bank.
On the first day, the bank suffered a significant volumetric attack that lasted five to six minutes, but consumed bandwidth at a rate of dozens of gigabytes per second.
Another attack, that lasted fifteen minutes, took place on the second day, targeting the second domain of the bank. On the third day, the same domain that was targeted the previous day was hit with a long duration attack.
We could see that the first and second attacks were reconnaissance attacks, executed to evaluate which of the two domains was more vulnerable. It is clear that the second domain was more susceptible since it was hit much harder in the third attack.
In parallel, we detected that there was another short-duration spike attack that targeted one of our Telco customers.
Just two hours later, there was another attack against a large utility organization. Because of this pattern, we were able to identify that all three attacks were performed by the same attacker and could warn and better protect our customers against further attacks.
Comparing the volume of bandwidth we’ve encountered on the first day of the attacks, to a DDoS attack’s average peak size of 7.39 Gbps, as reported by SCMagazine, we can see that short-duration attacks use large volumes of traffic in short, shotgun-like bursts.
Attackers leverage these short-duration attacks to evaluate which companies and organizations are easiest to infiltrate.
We assume that this also has to do with the availability of resources. These types of attacks are more likely to come from smaller, private groups that are shorter on resources, as opposed to criminal groups or countries which have access to unlimited resources and can therefore launch long-duration attacks from day-one.
Here’s what we’ve seen over time:
Mitigation
When it comes to short-burst attacks, time is of the essence. Attacks are likely to go under the radar and leave no time to respond.
Organizations managing multiple web domains must have the ability to centralize incoming data, preferably by working with the same security vendor across all their domains.
This enables them to predict attacks by analyzing trends and patterns across their sites. Organizations should demand this capability from their security vendors, who should also be willing to use data from various customers in order to predict potential attacks on other customers, as described in the above case study.
We see a growing number of short duration attacks across our customer base. Awareness to this new pattern is key: customers typically assume that the attack is over, while this may actually be a sign for a much larger attack coming through.
In light of this new pattern using services and tools that can aggregate attack information across customers and websites is an ideal way to predict and avoid the massive DDoS attacks about to come.

Gold Hits Record $5,110/Ounce Amid Trump Tariff Threats, Geopolitical Fears

Gold prices smashed through $5,100 per ounce on Monday, January 26, surging to a historic peak of $5,110.50 as investors rushed into the safe-haven asset amid escalating geopolitical tensions and U.S. policy volatility.

Gold
Spot gold climbed 2.2% to $5,089.78 by 0656 GMT, while U.S. February futures rose similarly to $5,086.30. The metal, up 64% in 2025—its strongest annual gain since 1979—has now advanced over 18% year-to-date, fueled by safe-haven buying, anticipated U.S. rate cuts, China’s 14th consecutive month of central bank purchases in December, and massive ETF inflows.
Analysts point to a crisis of confidence in U.S. assets, sparked by President Trump’s erratic threats last week. He retreated from tariffs on European allies to pressure Greenland seizure, then vowed 100% tariffs on Canada over a potential China trade deal and 200% on French wines to push President Emmanuel Macron toward a “Board of Peace” initiative.
“This Trump administration has caused a permanent rupture in global norms, driving everyone to gold as the sole refuge,” said Kyle Rodda, senior market analyst at Capital.com.
A weakening dollar—hit by a rising yen and pre-Fed meeting caution—further boosted gold’s appeal for non-dollar holders, with markets eyeing possible yen intervention.

Firm Identifies AI as Common Denominator in Entertainment Industry’s 2026 Security Threats

In its Kaspersky Security Bulletin, the cybersecurity company’s researchers identified critical threats expected to affect the global entertainment industry in 2026, from ticketing and visual effects pipelines to content delivery networks, games and regulation.

Artificial intelligence is changing how people buy tickets, watch movies and play games – and it is also changing how malicious actors target those experiences.
The entertainment industry is particularly sensitive to AI because the technology does not only automate back-office workflows; it increasingly creates and imitates the core product itself – human-centered stories, performances and visual experiences.
Kaspersky researchers highlighted five critical threats emerging as AI integrates deeper into entertainment workflows and consumer experiences.
What happens when ticket markets become an arms race between algorithms and scalpers? Kaspersky predicts that AI will make dynamic pricing faster and more granular, while also giving scalpers better tools to identify profitable events, deploy bots at scale and manage resale pricing across multiple platforms.
Even when artists choose fixed face values, AI-driven resellers can recreate “dynamic” pricing on secondary markets by adjusting prices in real time based on demand signals.
How will AI-commodified visual effects affect the risk of leaks? As high-end computer-generated imagery becomes more accessible through cloud-based AI platforms, studios will connect to larger networks of small vendors and freelancers.
Kaspersky expects attackers to target this extended supply chain by compromising render farms, plug-ins or small post-production houses in order to quietly steal sequences, assets or episodes before release, bypassing more heavily protected studio environments.
Could content delivery networks become a direct target? CDNs now carry unreleased episodes, game builds and live streams for many major entertainment brands, concentrating valuable content in a small number of providers.
AI-enhanced attackers will be able to map CDN infrastructure more efficiently, locate where premium content resides and search for weak credentials or configuration errors. A single successful compromise could expose multiple titles at once or allow malicious code to be injected into legitimate streams.
How will generative tools change abuse patterns in games and fan communities? Players and power users will continue to jailbreak in-game AI companions and content editors, and to use external generative models to produce material that would normally be blocked – such as hyper-violent or sexualized scenarios – and then reimport it into games, mods, or fan videos.
There is also a risk of personal data appearing in “creative” outputs if training or fine-tuning data is not properly cleaned, for example, when lyrics, dialogue, or imagery inadvertently include real names or other identifying details.
What role will regulation and compliance play for AI in creative work? Lawmakers and industry groups are moving toward rules that require transparency about AI-generated media and clearer consent and licensing practices for training on copyrighted material.
Kaspersky expects this to drive the creation of new roles inside entertainment companies, similar to COVID-compliance managers on film sets, focused on AI governance: checking how AI tools are trained, how they are used in production and marketing, and whether they comply with contractual and legal requirements.
“As we examined different parts of the industry, it became clear that AI is the thread running through most of the emerging risks.
“By diving into this, we wanted to highlight that AI will not only help defenders detect anomalies faster, it will also help attackers model markets, probe infrastructure and generate convincing malicious content.
“Studios, platforms and rights holders need to treat AI systems, and the data behind them, as part of their core attack surface, not just as creative tools, and build security and governance around that reality,” said Anna Larkina, web content analysis expert at Kaspersky.

Firm Detected a Fivefold Surge in QR Code Phishing Attacks in the Second Half of 2025

Kaspersky has reported a spike in phishing emails containing malicious QR codes. Detections for these jumped from 46,969 in August 2025 to 249,723 in November 2025 – a more than fivefold growth – as cybercriminals increasingly exploit QR codes, a trend that will likely continue in 2026.

Attackers use QR codes in emails more frequently because they provide a simple and cost-effective way to conceal malicious URLs, evading detection by many protective solutions.
These QR codes are often embedded directly in email bodies or, even more commonly, within PDF attachments – an evolution that both masks phishing links and encourages users to scan them on mobile phones, which may have weaker security than work PCs.
Malicious QR codes commonly appear in mass phishing campaigns as well as targeted ones. Links embedded within them may lead to:
- Phishing forms impersonating login pages for services like Microsoft accounts or internal corporate portals, designed to steal usernames, passwords, and other credentials.
- Fake HR notifications urging employees to review or sign documents, such as vacation schedules, or even view lists of terminated staff, ultimately directing to credential-stealing sites.
- Fraudulent invoices or purchase confirmations in PDF attachments, often combined with vishing (voice phishing) tactics that prompt victims to call provided phone numbers to “cancel” or clarify the transaction, enabling further social engineering attacks.
These tactics exploit trust in routine business communications, leading to credential theft, account takeovers, data breaches, and financial fraud.
“Malicious QR codes have evolved into one of the most effective phishing tools, particularly when hidden in PDF attachments or disguised as legitimate business communications like HR updates.
“The explosive growth in November 2025 highlights how attackers are capitalising on this low-cost evasion technique to target employees on mobile devices, where protection is often minimal.
“Without advanced image analysis at the email gateway and safe scanning practices, organisations are left vulnerable to credential compromise and downstream breaches,” comments Roman Dedenok, Anti-Spam Expert at Kaspersky.
To defend against this escalating threat, Kaspersky recommends educating employees on cybersecurity and deploying a mail server security solution such as Kaspersky Security for Mail Server that provides trusted and secure corporate email exchange, countering spam, email-borne infections, all forms of phishing, business email compromise (BEC), QR code attacks, and other threats.
