Since October 7, Israeli sites have been targeted by DDoS at rates 275% higher than average. Sites targeted have primarily been in the government and financial sectors, and attacks are coming from many hacktivist groups that are anti-Israel, including Killnet, Anonymous Sudan, AnonGhost, and others. Attacks coming from Iranian and Russian IP addresses have also risen sharply.

A United Arab Emirates-based news site was targeted this month with XSS attacks coming from just 18 IP addresses leveraging Java-based hacking tools. These addresses spanned several countries, including the US, France, India, Hong Kong, and even from within the UAE itself. The attacks lasted three days in total, reaching a peak of almost 5M attacks per day. The motives behind this coordinated effort remain unclear, but the volume and persistence of the attacks underscore the vulnerabilities even well-established websites can face in today's digital landscape.

A US food chain experienced account takeover this month, with malicious login attempts 1000% higher than average. The site offers rewards accounts that can be used for perks like free food, as well as delivery options where addresses and credit card numbers are saved to the account. This stored information, while meant to streamline the ordering process, also makes these accounts particularly enticing for hackers. The combination of rewards and sensitive personal information underscores the potential risks and ramifications of such security breaches for both the company and its customer base.

Imperva Account Takeover prevention uses multi-layered detection to block fraud.

Several recent vulnerabilities–in Juniper, Progress, Atlassian, Microsoft, JetBrains, and F5 software–are blocked by Imperva. These vulnerabilities affect a wide variety of products, although several are remote code execution bugs. These vulnerabilities, if left unaddressed, could lead to unauthorized data access, system disruptions, and other malicious activities. Imperva is dedicated to delivering robust security for its customers.

A Korean gambling site was targeted this month with application layer DDoS reaching 2.6M RPS, and coming from 7K IPs. This incident is not isolated; it aligns with an alarming upward trend in application DDoS attacks over the past few months, especially with the exposure of the HTTP2 Rapid Reset vulnerability. Such attacks underscore the evolving nature of cyber threats and emphasize the need for robust security measures, especially for online platforms that handle significant user traffic and financial transactions.

What is the Cyber Threat Index?

The Cyber Threat Index is a monthly measurement and analysis of the global cyber threat landscape across data and applications.

The Cyber Threat Index provides an easy-to-understand score to track cyber threat level consistently over time, as well as observe trends. The data is (when applicable) also analyzed by industry and by country, to provide further analytics and insights.

The Cyber Threat Index is calculated using data gathered from all Imperva sensors across the world including over:

  • Over 25 monthly PBs (Peta Bytes1015) of network traffic passed through our CDN
  • 30 billions (109) of monthly Web application attacks, across 1 trillion (10¹²) of HTTP requests analyzed by our Web Application Firewall service (Cloud WAF)
  • Hundreds of monthly application and database vulnerabilities, as processed by our security intelligence aggregation from multiple sources

Viewers of the global Cyber Threat Index can dive deeper into the score & drill-down for individual industries and countries, and also view historic Index scores.

On a monthly basis, our security experts are analyzing the data, to create insights about events and trends in data & application security based on the data we see. When applicable, we may also suggest recommendations for enhancing the security posture against the threats we see.

How is the index calculated?

The index is based on a number of ingredients: network traffic, attack traffic and vulnerabilities.

We store attack data, as well as statistics about the network traffic we see from our Cloud WAF. This data is sent from our Cloud WAF proxies to our data warehouse, where it is enriched & aggregated.

On a daily basis, we run analytics on the data we collect, to calculate a daily risk score per site, per industry & per country.


When calculating the vulnerabilities’ risk, our assessment is that:

  • The more severe the vulnerability – the higher the risk (Impact can be larger, for example: taking over a server vs disclosing system information)
  • The more recent the vulnerability – the higher the risk (The assumption is that patching of systems takes time, therefore there will be more vulnerable systems accessible)
  • If there is a public exploit, the risk is higher as more attackers has the ability to exploit the vulnerability, and the more wide-spread it is the higher the risk.

DDoS Attacks

We store statistics on both network DDoS attacks and application DDoS attacks.

Network DDoS attack statistics include details about the duration of the attack, the volume of the attacks, number of sources and their proportion in the attack, different ports and methods (e.g. SYN flood, amplification etc.). These statistics are calculated and stored for attacks both in terms of packet per second and in terms of bytes per second.

Application DDoS (Layer 7 DDoS attacks) statistics include information about the duration of the attack, the volume of the attack, the tools that were used and the different countries it originated from in terms of requests per second.

We normalize all DDoS attacks statistics against the statistics we have about legitimate traffic, to prevent bias for increased/decreased amount of assets we protect (Globally or for a certain industry/country).

Application Security Attacks (As seen in the wild)

At first, instead of dealing with a huge amount of daily attacking requests, we aggregate them into attacks (Each attack can have a very large number of HTTP requests as part of it). For each attack, we check:

  • The highest risk level of triggered rule within that attack (For example: an SQL Injection attack has more weight than an information disclosure attack).
  • The higher the intensity of the attack, the higher the risk.
  • The newer the mitigation, the riskier the attack (We constantly add mitigations to our cloud WAF, and the assumption is that newer attacks has more success ratio than older ones).

For the analytics and insights we provide, we also enrich the data, for example:

  • Adding target industry classification for the applications being attacked.
  • Adding source & target countries.
  • Adding source network types (For example: public cloud, TOR, etc).

The risk is then calculated by removing the lowest-risk attacks, as they’re meaningless in terms of added risk, and determining the risk is done by normalizing attack traffic against normal traffic. The logic to this normalization is that we don’t want the index to be affected by increased/decreased traffic (For example: if we have 20% more traffic due to new customers in a certain month, we don’t want it to affect the risk index).
