Here’s a reminder to our readers: Malwarebytes will be participating in the up-and-coming IP EXPO Europe. If you’re in London this week, please don’t forget to drop by stand AA3 and say hello to your friendly Malwarenaut!
Last week, we touched on an atypical Skype hacking tool, which is actually a backdoor program; the growing threat of phishing brought to us by Michael Osterman, our latest guest blogger; tech support impersonators that banked on the Malwarebytes’s brand; and an Instagram account that just tugs on the heartstrings the wrong way.
Senior Security Researcher Jérôme Segura found and documented more hot malvertising campaigns based on data captured from our telemetry. First off, adult sites Pornhub and YouPorn were used to affect millions of users, following the xHamster attack several days ago. Next, rogue advertisers were able to use Google’s AdWords in a malicious way to point users to a fake blue screen of death (BSoD) tech support scam.
Malware Intelligence Analyst Christopher Boyd reported of spammers misusing Indiegogo, a popular crowdfunding site similar to Kickstarter. We’ve seen similar spam campaigns before on deviantArt, LinkedIn, Steam, and even on Celine Dion’s official website.
Boyd also published an interesting phishing find that highlighted the tactics the fraudsters used while incorporating common online elements: a PDF file, a URL shortener, and an error message. The tactic should serve a reminder for anyone to never let their (our) guard down, knowing that phishers can extract credentials and information from anyone, even from security savvy users.

- Drop-dead Simple Exploit Completely Bypasses Mac’s Malware Gatekeeper. “Patrick Wardle, director of research of security firm Synack, said the bypass stems from a key shortcoming in the design of Gatekeeper rather than a defect in the way it operates. Gatekeeper’s sole function is to check the digital certificate of a downloaded app before it’s installed to see if it’s signed by an Apple-recognized developer or originated from the official Apple App Store.” (Source: Ars Technica)

- Opinion: Fight Phishing Without Blaming Victims. “Yes, anti-phishing training is effective. But only to a certain point. Training can reduce the number of malicious links that get clicked on within an organization but it will never eliminate the threat. Criminal hackers are crafty, and there will always be that perfectly designed e-mail that’ll fool even the savviest recipient. So, if your security policy is to rely 100 percent on anti-phishing training, you’re about to have a very bad day.” (Source: Christian Science Monitor)

Instead, it appears to be the work of what experts call an “Internet of Things (IoT) vigilante” who wants to protect routers and other IoT devices from malicious actors.” (Source: Security Week)
