Why do small sites get hacked?

small-sites3
If you think your site won't be hacked because it's too small to matter, think again. I'll show why that is a false and dangerous assumption. Many site owners and webmasters think that hackers only care about popular, highly-ranked websites. They are wrong. High traffic volume helps boost earnings on partner programs by redirecting visitors to other sites, gets more views of unauthorized advertisements and attracts more clicks on rogue links. But that is not the only way hackers make money. Unprotected sites with low traffic volume are equally attractive to hackers. It is the way they are used that differs from how hackers monetize more popular websites. Any normal site, with an audience of ...

What to do if your Website is Hacked: A Disaster Recovery Plan

website-hacked
Thousands of websites get hacked on a daily basis. Actually, thousands out of the many billions of websites on the Internet is quite a low percentage, but if you got unlucky and your website is among those, you need to take it seriously, and respond to the threat quickly and wisely. Unfortunately, very often, website owners are 100% sure that they won't ever be a victim, and do not have a valid disaster recovery plan for such cases. Or, if they do, the plan consists of just one bullet point: I was unlucky and the plan is to shut down my business. In this article, I cover that gap and offer you a solid disaster recovery plan if your website got hacked. Once Upon a Time, a Website Got Hacked… ...

Black Friday Phishing, Anyone?

black-friday4
​ If this year's Black Friday/Cyber Monday online shopping season is anything like last year's, it'll be a turkey shoot, not only for shoppers, but for hackers too. Bargain hunters are impetuous by nature, the online species more so. In the heady excitement of discount fever virulent throughout the forthcoming holidays, shoppers are more likely to click a phishing link without checking it first. They're also more likely to be shopping on a mobile device , where it's harder to see if a site is genuine or not. Billions of dollars will pass from customer to online shop, some of it through, or aided by, your servers. Your success as a hoster depends on the success of your customers' sites being ...

How Spammers Spam

spammers
Twenty years on and spam is still a problem. I'll look at why that is and what we can do to reduce or prevent it. Contrary to popular belief, hacking a site and uploading malicious scripts onto it is not the only way spamming gets a foothold. There are other ways. For example, it could be because of a compromised account, the use of script vulnerabilities, or an incorrectly configured mail server. The diagram below shows an overview of the methods. ​ In this article, I'll look at the different ways unsolicited email (spam) can emanate from a web server, and some of the ways you can stop it. Spamming by hacking A hacked site or server is the most common reason behind an outbreak of spamming a...

DON’T GET BLACKLISTED ON BLACK FRIDAY

dont-get-blacklisted
Black Friday-Cyber Monday is the busiest e-shopping weekend of the year, so don't let hackers get your site banned by search engines. If your site gets compromised by malicious actors and starts spreading malware, it will be blacklisted by Google safe browsing, Yandex SB, McAfee, ESET, and other security services, which means that online shoppers will not find your site in search engines. This will inevitably disrupt your business, and e-commerce sales will be hit the hardest. With Imunify360's multi-layered approach to complete cyberdefense, you'll protect your sites/servers from malicious intent and stop malware from running on them in the first place. Imunify360 also monitors the blacklis...

Why Does Site or Server Load Increase?

Why server load increases
There's only one good reason why the load on your hosting server starts increasing–the rest are bad. I'll look at how and why they all happen. I was often contacted by site owners who had a problem with high server load. This common condition is first noticed when an owner gets a warning message from their hosting company. Such messages can be precursors to the blocking of the site, and it can happen to almost any site owner or webmaster. This article covers the different reasons why the load on a site or server might be increasing, and what can be done about it. Webmasters usually find out about excess load from their hosters. Hosting companies regulate and control resource usage for each h...

Patterns of thought: the psychology of weak passwords

psychology1
In this article, I look at why webmasters, site administrators and their users choose and use weak passwords. Later, I recommend ways to create passwords that are reliable and resistant to brute-force attacks. Warnings that the internet is increasingly an unsafe environment appear with alarming regularity in studies commissioned by companies specializing in information security. The growing number of web attacks and the increasing activity of the hacker community require a new discipline and focus on security. But while cybersecurity experts are talking about high technology and advanced protection, it seems a rudimentary rule has been forgotten: the use of strong passwords. Unreliable passw...

Avoid Multi-Site Hacking – Part 2

Security solution for web hosting
In Part 1 , we looked at security isolation as a technical solution for preventing infections on one site spreading to neighboring sites in multi-site hosting systems. In Part 2, we'll consider other non-technical ways to beef up multi-site protection. Site security = technical protection + organizational measures If you don't use security isolation on sites in the same hosting account, you should at least give each site its own account. However, this is often impossible, as the combined sum of each site's content resource needs (disk, memory) is too great. This is where the next elements of complex security come in. I call them organizational measures . Here are some examples. ​ Secure work...

Avoid Multi-Site Hacking – Part 1

avoid-part1
Running shared or VPS servers has risks. When one site is hacked, neighbors succumb shortly after. In this two-part article, I'll explain the risks in detail and what you can do to mitigate them. Shared hosting and VPS servers allow you to host several sites within one user account. If you're a webmaster, a web studio, an Internet agency, or a business owner, you do this not only for convenience but also to save money, as it is cheaper than buying separate accounts for each site. But there's a problem. Multi-site accounts are vulnerable to hacking and the subsequent infection of the entire hosting account. Often, there are dozens of "patients" (tenants) on the same site who urgently need tre...

Why every month should be National Cybersecurity Awareness Month

ncsam
This month, October 2018, in the US it is the 15th National Cybersecurity Awareness Month . Another month, another 'awareness' . Does this suppose that all the other 11 months we should be less aware? Do hackers make a special effort to be nicer in October? Do they leave love letters on your server instead of malware? Does it help if you live on Tokelau*? No. EVERY month is cybersecurity awareness month, and every week and every day and every second of every day, everywhere. Because cyber attacks are automated. Hackers are using scripts and scalable tools to do the grunt work, the same way you make scripts to automate tedious tasks on your servers. Here's a recipe for success this cybersecur...

How Proactive Defense works: watch the webinar recording to learn why it is so effective in stopping malware

layers
Firewalls and malware scanners focus on protecting against known attacks, but how do you protect against new security threats? With Proactive Defense in Imunify360 . It proactively stops malware from attacking your websites and servers. It intercepts all activity in real time, analyzes the behavior of PHP scripts, and then stops any known or unknown malicious codes from being executed. Proactive Defense is very effective because it analyzes what PHP scripts do rather than what is actually in the code or file.  Here you will learn how Proactive Defense works and how it stops even the malware that scanners are unable to detect.  View the recorded webinar here.

How to stop playing Whack-A-Mole with malware and actually protect servers from attacks

whack
​ Software vulnerabilities are constantly being exploited and monetized, and organized crime now consist of large development teams with substantial budgets. It has become a profitable industry that has seen rapid growth, fueled by ransomware schemes and cryptomining exploits, all without dire consequences. Malware is used by attackers to steal data, bypass access controls, remotely execute files, modify system configurations, and much more.  Web applications, such as WordPress and its plugins, are especially appealing to attackers as they are widely used and easily exploited, but Imunify360 -- with the newly released Proactive Defense -- can protect those applications against both...
