Data Breach Prevention

Glaring headlines in the March 29, 2016 The American Lawyer detailed that 48 of our nation’s top law firms were specifically targeted by a Russian hacker seeking to trade on M&A information. Most of the firms found out they were a target only because their name was included in the article. On March 22, 2016 the FBI issued an alert warning law firms of criminals seeking access to their networks.

What should you do? First, realize that some of the largest firms have experienced breaches. And they have huge IT staff, and lots of money to throw at the problem. Don’t throw up your arms in disdain and say you have no chance by comparison. For firms of all sizes I recommend . . . READ MORE

Is Your Apple Device Safe from Malware Infection?

Apple customers, particularly Mac users, are normally adamant about the fact that their computers don’t need protection from viruses, Trojans, Ransomware, or other threats that impact Windows PCs on a day-in-and-day-out basis.  Is it true, or a myth?  The truth is that while the general threat level is far lower on a Mac than a PC, the OS-X operating system is not immune.

Apple has been a target of lesser opportunity only because criminals invest their time, money and resources where the return will be greatest.  That has historically targeted PCs almost exclusively, due to their market share.  As the installed base of Macs continues to grow, so does the appearance of threats.  How quickly?

A recent blog post on the Official Security Blog site of Malwarebytes states: “The popularity of Macs leads to more cybercriminals wanting to write malicious code for OS X. Although still much lower than PCs, the number of threats targeting Apple operating systems has grown steadily, with a spike in Mac infections observed over the last 18 months. A recent study by Bit9 + Carbon Black found that the number of Mac OS X malware samples detected in 2015 was five times greater than in the previous five years combined.”

If you are not deploying security software on your Apple device, now would be the time to do so.  Don’t wait to be a victim of something like the Ransomware  KeRanger , which was  downloaded  by  around  6,500  people  within  the 12-hour  period  that  it  was  available.  Some  of  those  users  had  their  data  completely  destroyed.

Computer Security Alert: Protect Your PC From a Data Dump

A data what?  Yep, you  heard it right.  There’s a new computer security threat afoot which can fill your hard drive in seconds.

This new threat was just reported in BBC News : Technology.  According to the report, the vulnerability has been created by a loophole in the programming of HTML5.  While most websites are currently built using version 4 of the Hyper Text Markup
Language (HTML).  However,  that code is gradually being upgraded by the newer version 5.

One big change brought in with HTML5 lets websites store more data locally on visitors’ PCs.  Based on one’s browser, there is a limit of how much data can be placed on  your PC.  However, the loophole is enabled by a software routine which endlessly creates new, linked websites, enabling each  to dump huge amounts of data onto a target PC.  Oh, and did I mention that the actual creation of the linked websites, and data dumping takes place literally in seconds?

What data will it dump?  Well, it could be pictures of cartoon cats, as done in the demo created by Developer Feross Aboukhadijeh, the discoverer of the loophole. According to the news report, In one demo, Mr Aboukhadijeh managed to dump one gigabyte of data every 16 seconds onto a vulnerable Macbook.

Most major browsers, including Chrome, Internet Explorer, Opera and Safari, were found to be vulnerable to the bug.  Only Mozilla’s Firefox capped storage at 5MB and was not vulnerable.

What can / should you do?  Well, this has been reported, and is being worked on.  Your number one defense is to have a back-up emergency boot disk, so that if your hard drive is crammed with cr*p, you can still boot your computer.  You also need to have a good solid back-up, so that you can restore your software and documents after you reboot.

If you use one of the impacted browsers on either MAC or PC platform, you may want to make sure that your anti-virus software is set to scan sites for malicious code before you actually connect.  There is no mention in the report as to whether this is detectable, so I can’t say for sure it will protect you.  But it’s worth a try, and it’s always a good idea anyway, since malicious code can be placed on just about any web site.  Last, stay away from web sites which are known to harbor nasty stuff, like file and music sharing and game sites.  At least until you’ve heard this problem is resolved.
