What you need to know about BERserk and Mozilla

Published: September 25, 2014 Reading time: 1 min

The Intel Security Advanced Threat Research Team has discovered a critical signature forgery vulnerability in the Mozilla Network Security Services (NSS) crypto library that could allow malicious parties to set up fraudulent sites masquerading as legitimate businesses and other organizations. The Mozilla NSS library, commonly utilized in the Firefox web browser, can also be found in Thunderbird, Seamonkey, and other Mozilla products. Dubbed “BERserk”, this vulnerability allows for attackers to forge RSA signatures, thereby allowing for the bypass of authentication to websites utilizing SSL/TLS. Given that certificates can be forged for any domain, this issue raises serious concerns around integrity and confidentiality as we traverse what we perceive to be secure websites. ...

New Facebook scams in 2014

Published: August 22, 2014 Reading time: 3 min

So many Facebook scams in 2014 have been a little worrying even though at first they all seem innocent enough, but these are social scams to lure users in to gain money or access to computers. One particular Facebook scam this year was the “Robin Williams goodbye video”, which was apparently made before his death. This fake BBC News video is a scam and no such video exists. The “Robin Williams goodbye video” started to circulate on Facebook and asks users to share the video before they can watch it, DO NOT click on it. There is no video so no point on sharing it, Symantec explains in detail that when Facebook users click on the video it asks them to either fill out a survey or install an application. When the survey is complete the scammers gain money for each one completed. ...

Facebook Virus That Drains Your Bank Accounts: What You Need to Know

Published: June 6, 2013 Reading time: 4 min

This post has been shared originally by Malwarebytes Blog: The word about the Zeus Trojan back on Facebook has spread as fast as the malware itself across many news sites. Awareness and education about online dangers is essential but headlines like “Malware That Drains Your Bank Account Thriving On Facebook” instill fear while at the same time blame Facebook — something that may not be entirely justified. Malicious links on social networking sites are nothing new (Twitter, Linkedin to name a few). They have been, and continue to be, abused by spammers to peddle fake AV or redirect to exploit sites distributing all sorts of nasties. ...

Symantec vs AV-Comparatives, Which one do you trust?

Published: April 25, 2013 Reading time: 5 min

Cross-posted from PCMag SecurityWatch: Last week independent antivirus lab AV-Comparatives released the results of an on-demand antivirus detection test. The fact that Microsoft came in near the bottom wasn’t big news; the fact that Symantec scored even lower was surprising indeed. In a blog post released today, Symantec decried the entire practice of performing on-demand malware scanning tests, calling it “misleading.” In the early years of antivirus testing, every test was an on-demand scanning test. Researchers would assemble a collection of known malware, run a full scan, and record the percentage of samples detected. Modern labs work hard to devise tests that more closely reflect a user’s real-world experience, taking into account the fact that the vast majority of infections enter the computer from the Internet. Symantec contends that only the real-world sort of test is valid; I don’t entirely agree. ...
