for enterprise webmasters or website operators, the website is the core channel connecting users and brands. Once the website is hacked, it will not only lose traffic, damage brand reputation, but also face the legal risk of user data leakage. However, website hacking is not without warning, and most attacks will leave abnormal traces traceable in the early stage. This article will sort out various precursor signals of website hacking, combined with practical investigation methods, to help operators find risks in advance, take protective measures in time, and avoid subsequent major losses.

, the site was black before the background operation is abnormal?

website background is the core management entrance, but also the key target of hacker attacks, the precursor of the website being hacked is often reflected in the abnormal changes in the background.

1, unfamiliar login record or permission change

the operation log of the login background, if there is a non-team member's Internet Protocol Address login record, or a remote login trace during non-working hours, it is very likely that the hacker is trying to penetrate. In addition, if it is found that an unauthorized administrator account is added, or the authority of the original account is inexplicably upgraded, which is also a typical precursor to the website being hacked, indicating that the hacker has initially obtained background control.

2, function module abnormality or operation card

the original smooth background management function suddenly appeared card, such as article release, page modification and other operations delay is too high, or some functional modules disappear inexplicably, can not load normally, it may also be a hacker in the background implanted malicious script, occupy server resources or tamper with the core code caused, which is one of the early signals of the website was black.

2, the website was black before the page content change?

the front-end page of the website facing the user is the most intuitive performance carrier after the website is hacked, but before the attack is completed, there will be subtle changes.

1, the page code appears strange content

check the source code of the front-end page of the website, if you find that the head or bottom is embedded with unfamiliar jump links, encrypted codes, or a lot of keyword stuffing content that has nothing to do with the theme of the website, this is usually a hacker for subsequent implantation of black hat SEO content, which is a typical precursor to the website being hacked. This type of code may not affect the normal display of the page in the early stage, but will quietly guide the search engine to crawl illegal content.

2, page loading abnormality or jump disorder

users visit the website, occasionally the page loads slowly, the style is disordered, or when clicking the normal link, jump to an unfamiliar third-party website, even if it returns to normal after refresh, it cannot be taken lightly. This intermittent jump abnormality is often a hacker testing a malicious jump script, which is a pre-trial behavior of the website being hacked.

Third, the traffic and data fluctuations before the website was hacked?

changes in data such as website traffic and inclusion, it can also indirectly reflect the latent risk of website being hacked, especially abnormal data fluctuations need to be paid attention to.

1, search engine indexing abnormal fluctuations

through the search engine webmaster platform to view the amount of website inclusion, if the amount of inclusion suddenly increases in the short term, but the newly included pages are unfamiliar illegal content, or the amount of inclusion drops sharply, and the core page is removed from the index by the search engine, which may be a precursor to the website being hacked. Hackers may have tampered with the content of the website, causing search engines to identify illegal information, triggering a preliminary punishment mechanism.

2, traffic sources or abnormal user behavior

analyze website traffic statistics, if a large amount of junk traffic from unfamiliar regions or illegal channels is found, or the user's stay time plummets and the bounce rate rises sharply, it means that the website may have been implanted with malicious code, which affects the user's normal access experience. Such abnormal data is often earlier than the explicit performance of the website being hacked, which is a key indicator for early investigation.

4, the website was hacked before the security alarm triggered?

most websites will be equipped with basic security tools, these tools trigger the alarm, is a direct warning signal that the website is hacked.

1, server security software alerts

server frequently trigger malicious file interception, port scanning alerts, or detect abnormal process occupancy, it means that hackers are conducting penetration tests on the server to try to find vulnerabilities. When the number of such alerts suddenly increases, they must be investigated immediately. This is the core early warning signal before the website is hacked.

2, Domain Name, or SSL Certificate Abnormal Alerts

if you receive the domain name service provider sent abnormal notification domain name resolution, or the browser prompts the site SSL certificate is invalid, there is a security risk, it may be that hackers tampered with the domain name resolution record, or forged false certificate, for the subsequent site is black phishing attack to prepare, such alerts need to be dealt with in the first time to avoid users mistakenly into the phishing page.

To sum up, the precursor of the website being hacked involves four dimensions: background, page, data, and security tools. From unfamiliar login records to page code changes, from abnormal traffic fluctuations to frequent security alerts, every signal may be an early warning of attacks. Website managers need to regularly investigate these anomalies and develop the habit of checking logs and analyzing data every day in order to intervene in the early days of the website being hacked, safeguard the security of the website, and avoid irreparable losses such as brand damage and user churn.
