There are still a few websites that can be trusted to be safe, even if they don’t follow all the rules of security.
But for the most part, it’s been hard to know how trustworthy the sites have been.
“There’s definitely a number of sites that have a very, very high probability of being hacked,” said David DeWalt, founder of the cybersecurity firm Kaspersky Lab.
“So, it is difficult to know which sites are actually legitimate.”
For example, the website of the American Heart Association, which promotes heart health and research, is hacked.
The hack can lead to people having heart attacks, DeWall said.
The American Heart Federation has been hacked and some members have been threatened.
The group also posted a video in September saying it had breached a security breach at the World Health Organization.
The video is still online.
On Tuesday, the FBI tweeted that it was investigating the hacking of the group, but it didn’t specify whether that was connected to the World Heart Federation.
Kaspersky says it has also seen a number, if not all, of sites on the black market that have been compromised.
It said the same could be said for some of the other popular sites that were linked to the hack.
There are also some sites that are being advertised by fake names that are very easily tricked into doing what they’re promoting, De Walt said.
The hacker group that took down the World Trade Center website, for example, has a name like The Internet.
That could make it easy for the hacker to convince someone that they are legit.
“If you have a fake name, you can easily get people to trust you,” DeWally said.
Some sites are not as easy to fool.
One of the websites targeted by hackers in the Boston Marathon bombing in 2013, for instance, was hosted by a company called DumpsterDumper, a fake domain name that used the email addresses of some of its users.
Dumpsterdumper was hacked on Tuesday and it is no longer available to view.
It has not responded to requests for comment.
There’s also the issue of whether a hacked website can be traced back to a specific individual.
There have been instances in the past of websites being compromised, Dewalt said, but the majority of the sites that can’t actually be trusted are still around.
“So if a site is hacked, it could be that it’s just a random user somewhere that gets hacked, and they just have no idea who the person is,” he said.
“That would make it hard to tell whether it was actually a legitimate site or not.”
In the case of a hacked site, the hacker would likely be able to find other people who are still using the same domain, but if there is a real person using that site, that would give investigators a way to trace them back to the person who created the website, he said.
“The people that use these sites are probably people that have no legitimate reason to use them,” De Wall said, adding that hackers may try to trick users into visiting their websites.
If that’s not possible, then there are several options to protect yourself, including using a proxy server or VPN.
DeWald said that most of the popular sites don’t have any protections.
The best option, however, is to use a VPN.
There are many, like TunnelBear, that will connect to your home network or your corporate network, he added.
“The VPN that I use works,” he wrote in an email.
“I can always go back to using that VPN if I have problems.”
If you’re not familiar with the technology, it basically works like a proxy that redirects all traffic to the computer you’re using, De Waal said.
