Celebrity Nudes and iCloud Phishing

Thursday, September 11, 2014 by Andrew Conway

The recent leak of celebrities personal photographs demonstrates just how weak our defenses are against determined attackers. From the internal evidence and the chatter on 4chan and Reddit, it does not look as if this was the result of a single attack or a single hacker. Various sources say that there was a ring of […]

Android Worms And How To Prevent Them

Wednesday, September 03, 2014 by Andrew Conway

Recently, a malware attack in China infected around 100,000 Android devices in a few days. FireEye described the attack in their blog, and christened it XXShenqi. They call it a phishing attack, but I prefer the term worm, in that infected devices sent SMS messages to the owner’s contact list attempting to convince them to […]

ICO Raid on Suspect Call Center

Wednesday, August 27, 2014 by Cloudmark

It’s been just a few months since the UK’s Information Commissioners Office (ICO) took down its last target — using UK mobile users reports to 7726. Last week though, the regulator struck yet another blow against spam SMS texting. This time the ICO raided a claims management call centre in the Welsh town of Llanelli. […]

The Cost of Beating Automated Turing Tests

Tuesday, August 19, 2014 by Andrew Conway

Most social networks and other free Internet services have some sort of verification in their sign up process to make sure that a real person is signing up, and not a bot. Spammers and other cyber criminals wishing to abuse the service will attempt to automate this process so that they can sign up for […]

Black Hat/Defcon 2014: Hacking the Internet of Things, and Things not on the Internet

Tuesday, August 12, 2014 by Andrew Conway

Security researchers have been talking a lot lately about the Internet of Things: the refrigerator that was unfairly suspected of sending spam, the light bulbs that display your WiFi network password, and so on. There were some fine examples of this at Black Hat and Defcon this year. Jesus Molina was staying in a luxury […]

Defcon 2014: Surprise Talk by John McAfee

Saturday, August 09, 2014 by Andrew Conway

“I know that the press has portrayed me alternately as a mad genius, and a mad psychotic genius,” said John McAfee. Having heard him talk I can safely say that I don’t know which of these is accurate. Not all the speakers at Defcon appear on the printed schedule. There is one complete track where […]

Black Hat 2014: Chip and PIN is not Hacker Proof

Friday, August 08, 2014 by Andrew Conway

Today we saw a mobile point of sale device (MPOS) compromised by a malicious credit card. Yes, I did get that the right way round. In a wonderful through-the-looking-glass exploit, Jon Butler and Nils (who like many hackers has no last name) demonstrated how the chip on a chip and PIN credit card could be […]

Black Hat 2014: Why I Hate Free Stuff

Thursday, August 07, 2014 by Andrew Conway

I was watching an excellent presentation by Rob Ragan and Oscar Salazar when I realized that I hate free stuff. Not of course the free stuff that I use, I’m fine with that. It’s all the free stuff that spammers and other cyber criminals exploit that ticks me off. Let me explain what Ragan and […]

Black Hat 2014: Google Products Might be Watching… Maliciously

Wednesday, August 06, 2014 by Tom Landesman

Both Android and wearable device security have been a common topic among talks at Black Hat this year, and it seems Google may have passed on some unintentional headaches in both arenas. Jeff Forristal of Bluebox spoke on worrisome security practices used by Android that affected all Android users since January of 2010. Dubbed “FakeID,” […]

Black Hat 2014: Cellular modem vulnerabilities threaten mobile users

Wednesday, August 06, 2014 by Aaron Lehmann

Mobile broadband modems are small USB sticks that connect a computer to the internet through a cellular network. The great convenience of being able to stay connected outside of areas with Wi-Fi has led to over 100 million of these devices being sold. However, security flaws in these ubiquitous modems may become a boon for cybercriminals. […]
