Wireless networks are everywhere, but they aren’t always secure. In New York City, where millions of people connect to free but insecure Wi-Fi hotspots every day, it’s the same story.
Chester Wisniewski, Sophos senior security adviser, explains just how easy it would be for hackers to take advantage of unsuspecting people, in a segment that appeared Monday night on ABC World News.
Watch the video below or on the ABC World News website to see the full interview with Chet.
Recently we measured spam volume from around the world to find out which countries are the worst spam offenders. As we expected, the United States sends out way more spam than any other country — 24.2% of all spam was from the U.S.
When you consider the country’s huge online population, it’s not surprising that the U.S. sends so much spam. Spam comes from “bots” — computers infected with malware and under the control of a criminal. “Bot masters” can use servers anywhere in the world to give the bots instructions. So spam-bots in the countries on our list aren’t the authors of the spam, they are more like the messengers.
While it’s interesting to call out the 12 “dirty dozen” countries that send the most spam by volume, we also like to look at the amount of spam by population. It’s a diverse list of nations, and even small countries have a big spam problem.
In celebration of SysAdmin Day, we built the Ultimate IT Throne to present to one lucky winner of our #SophosSysmas contest. On Friday, I had the pleasure of delivering the coveted prize to the new King of IT — Morgan Jones, Systems Administrator at STARA Technologies Inc., in Gilbert, Arizona.
Morgan looked pretty surprised when we showed up at his office to present him with the IT Throne, and he operated it like a natural (especially the automatic Nerf cannons).
We shot a cool video showing the creative effort behind the building of the IT Throne.
Earlier this year we launched a new series of network security appliances and we told you they were much faster; boasting new faster CPUs, lightening quick SSD drives for instance. Now we’ve got the test results that prove it.
Independent test vendor Miercom has done rigorous testing of the Sophos SG Series alongside comparative appliances from other vendors. We shared some data points from Miercom earlier this year which looked very good indeed. Now Miercom has made available more results – and I don’t think you will be disappointed.
We have an extremely cool prize to give away as part of our celebration of the 12 Days of Sysmas. It’s called the Ultimate IT Throne and, even if it won’t give you any real powers over your users or your bosses, it will make you feel like a king (or queen).
There’s a lot going on that demands your attention at nearly every moment, from the not-so-aware user who accidentally downloads new threats like the re-born Gameover malware, to old threats like users accessing insecure Wi-Fi networks.
IT pros, we’ve got your back. (And if you win our IT Throne, we’ll get your behind too).
The router and firewall is a critical piece of equipment in your network. It connects you to the outside world while also acting as your first line of defence against intruders. If your firewall gets compromised things get ugly – fast.
I want to share a little tip – did you know that we offer an amazing alternative to cheap consumer grade Internet routers?
The difference is, our software is enterprise class, fully maintained and free. Here’s how you can try our Sophos UTM Home Edition and our free Sophos UTM Essential Firewall for businesses.
There’s a little holiday coming up on July 25th called System Administrators Appreciation Day (or SysAdmin Day for short). At Sophos, we’ve honored SysAdmin Day before, but this year we’re celebrating 12 Days of Sysmas — to show our appreciation for all that you do every day of the year.
We have some cool prizes to give away, some funny videos to hopefully give you a little comic relief, and one amazing grand prize you need to see to believe.
Here’s what’s happening over the next 12 days of Sysmas …
Last week, I joined millions of people in cheering on Costa Rica during their improbable World Cup quarterfinal match against the Netherlands. Remarkably, the Ticos held a superior Netherlands team scoreless through 120 minutes of regulation and extra time.
The key to their defense was a level of coordination I have not seen from other teams. Throughout the match, every player seemed to be involved in the defense at every moment. They moved like clockwork, communicating and shifting positions to keep the ball out of the goal.
Wouldn’t it be great if security technologies worked together as elegantly and effectively as Costa Rica’s defense?
Microsoft’s takedown of the No-IP dynamic DNS service generated a lot of controversy when legitimate customers were impacted by the disruption of 18,000 subdomains abused by cybercriminals.
Microsoft has done its fair share of good, frequently working with law enforcement to take out servers that control malware spewing bots, such as the ZeroAccess botnet. But in this case, Microsoft misfired and caused a lot of collateral damage, according to Sophos security adviser Maxim Weinstein.
In a new post at Dark Reading Maxim writes that the Microsoft vs. No-IP case highlights the need for “clear standards of abuse handling, and transparency on which service providers measure up.”
We may yet be accused of “going on” about the recent retirement of XP, but we feel justified in doing so as any systems you have that are still running XP will become more vulnerable over time.
Last week we saw a reminder that Oracle will not be issuing an update to Java on XP on the 15th July when it releases its regular update.
When we asked SophosLabs what they thought about Java on XP and the change in support status, they said that Java had been hard work even for supported operating systems – and so with no support for Java on XP there was no prospect of it getting any better.
