Send mixed messages: Mozilla wants you to try its encrypted file sharing

Share this story

Interesting new Send service being tested by Firefox.
Businesses we deal with dislike this type, due to the lack of auditability, of sending service, but the industry is screaming out for a standard file share/sending type of service.

There are vendors available, of course, but different businesses use different vendors – perhaps its time to look at TLS on email and increase the storage space the receiving capacity of email in general.

Twenty-five Percent of Emails Deemed Unsafe – Dark Reading

Share this story

A short video from Mimecast showing, from their recent Security report, that they deem around 25% of emails to be unsafe. Not surprising, and I would have put this figure, personally, a lot higher than this, considering that, by a fair percentage, a popular attack vector for users is through email.

Even with education, anyone can make an error by clicking on a malicious link or file in an email.

Do you use a cloud filtering service ? There are clear benefits of doing so, even more so if your email is housed internal to your business.

“Petya” Ransomware Goes Global

“Petya” Ransomware goes Global

There is a new strain of Ransomware from its original called Petya. Some sites out there are calling it completely new, NotPetya, and others see it is a variant and calling it PetWrap.

Whatever the case, the advice is always the same, look at how this is reportedly spreading, and put measures in place to mitigate as much as you possibly can.

According to many reports, the Ukraine has been badly hit, and it has been seen in several high profile UK business organisations.

Its also been confirmed that this Ransomware uses the Eternal Blue exploit, which was originally thought to have been developed by the US NSA as a digital weapon, and then subsequently leaked online by the hacker group known as Shadow Brokers.

Businesses who have not put measures in place such as disabling the SMB version 1 protocol (deprecated) or implemented the MS17-010 Microsoft Patch should do so now or as soon as possible. We believe this wont be the last exploit of this nature, and although simple measures such as black-holing the domain name used for the original Wannacry outbreak, and blocking known C&C servers, wont be effective and you could be fighting a reactive battle.

Businesses need to be robust in their security measures, have a solid response plan and be reactive as they can be to these modern threats otherwise these strains will continue to develop and proliferate. Don’t delay security patching.

Confirmed: Intel patches remote execution hole that’s been hidden in its…

Intel have confirmed that a patch will be released that will fix a remote code execution vulnerability (discovered in March 2017) which has been in its processors since 2009. This vulnerability allows hackers exploiting the flaw to silently snoop on a vulnerable machine’s users, make changes to files and read them, install rootkits and other malware, and so on. This is possible across the network, or with local access. #ITSecurity
