8 Most Overlooked Security Threats

Businesses know the obvious security threats to watch for, but some of the biggest dangers may not at top-of-mind.
2 of 9

Malvertising
Malvertising has fallen off the radar over the last year or so, says Jerome Segura, lead malware intelligence analyst at Malwarebytes. It still remains a threat, but for a new pool of targets.
Attackers previously targeted high-profile media sites with malware but learned those attacks generated a lot of attention, he explains. Now they've begun turning to smaller brand names with a lot of traffic but less visibility: foreign websites and file-sharing sites, for example.
'Those typically also don't care as much about visitors as a more high-profile website would,' Segura continues; as a result, malvertising often gets overlooked. 'How much do you care about making sure ads are clean and appropriate?'
Attackers primarily rely on malicious ads to generate revenue, but it's also used to collect identities or install malware that can be used to add a machine to a botnet in the future. Contractors are more likely to overlook malvertising compared with full-time employees who manage websites.
'A team that's not full time on the project won't be as familiar from start to finish,' says Logan Kipp, WordPress evangelist at SiteLock. 'They often overlook [malicious ads] because the look like they belong,' and unless they know to look at the source code, it won't seem suspicious.
Full-timers who maintain the app every day are more likely to notice if something is amiss. Businesses can mitigate the risk of malvertising by patching systems and using ad blockers.

I am a 33-year-old female, with no military affiliation just getting started with my bachelor's in cybersecurity.  Any thoughts or help to get started? Will my age and the fact that I have no prior military hurt me?

Re: Awareness training
It's easy to get excited about 0-days and network security because technology solutions are easier than human solutions. Education is important, but so is accountability: Security teams need to start bringing other teams (infrastructure, dev) into the fray.

64% of Americans work from home? Really? Perhaps you meant 64% of IT professionals? And even that sounds high.

z/OS and NSK are very secure, nothing like *nix and Windows.

The threat of connected devices can't be overstated enough. It needs to be the next phishing, in terms of public awareness. Particularly as voice-activated assistants are widely adopted.

@Dr.T: I'm not even so sure about the "more than ever"... Hackers have long known that social engineering is where it's at.  And Kevin Mitnick taught us this through his own exploits back in the day.

@Dr.T: Incorrect. But most if not all video would be disabled. And then for the sites you explicitly trust, you could enable as needed.

Re: 8 Most Overlooked Security Threats
Spot on. I started my IT career working in a IBM Mainframe environment. The economy of scale of going back to that platform would be a tremendous benefit to any corporate enterprise. When the top 50 banks in the world rely on z/OS as their primary server environment what do they know that the rest of the corporate world do not....... P.S. 35 years IT. Also performed the Common Criteria Evaluation of two to the z/OS security filters. Much more robust and safe than other platform implementations.....

Re: Awareness training
This is the bigger issue in security: Creating a culture of security.  Having the best security systems in the world technologically do little good if people are just willing to hand over login information, click on links willy-nilly, and let strangers into their datacenters.

Re: 8 Most Overlooked Security Threats
I'm afraid all OSes are not the same. Windows is a ramshackle lash-up which changes every version and is wide open to abuse. z/OS is far more robust and defendable than Windows and is capable of protecting Linux running under it. The 3rd party apps that run with Windows to give the total internet environment were not designed together and are bolt-ons with the same potential for interference with each other and by the bad guys. We all know that certain apps will not coexist on Windows and some have brought my system down before I uninstalled them.

PS I am not an apprentice but have nearly 50 years in IT as practitioner latterly as an author.
