How Hidden Vulnerabilities will Lead to Mobile Device Compromises

Image
Your mobile device can be hacked very easily without your knowledge. Even if an attacker can’t get into your device they can attempt to gain access to the sensitive information instead that is stored inside such as your places visited, emails and contacts. It's not just consumers who are targeted by cybercriminals, the rise of smartphones and tablets in the workplace and the increase in remote working has resulted in hackers targeting businesses via their mobile device vulnerabilities. Most individuals and organisations with very sensitive information, still do not take basic mobile security measures, even with the rising threats to our smartphones. According to a study by Intertrust on mobile security, the cost of mobile app hacks and violations will hit $1.5 billion by the end of 2021. Yet, network systems or even our desktop computers get more attention, with mobile device security continuing to be ignored by organisations across the globe every day. Three Ways a Mobile Device ...

How to Ensure Security when Buying a Refurbished or Second-Hand Smartphone

Image
Last year, a Which? investigation found that 31% of resold smartphone models from three of the major used and refurbished handset stores are no longer receiving security updates. Phone manufacturers only schedule data updates for a certain period after the release of a model, so those looking for an additional bargain in older devices could be putting themselves at risk. As well as security issues, second-hand smartphones that haven’t been wiped by their previous user can still contain sensitive data. Without following the proper steps, anybody considering selling their old phone on eBay or another marketplace could be exposed to fraud in numerous ways. How to Ensure Security When Buying a Phone Phone manufacturers often release information on their security updates, so checking your chosen model is still receiving these updates is essential to remain secure once you start using your new phone. The length of time phones are updated varies by manufacturer and by model. For example, App...

Image
   A roundup of UK focused Cyber and Information Security News, Blog Posts, Reports and general Threat Intelligence from the previous calendar month, April 2021. Think Before You LinkedIn! Business social media platform LinkedIn is being exploited by nation-state threat actors to target UK citizens.  The UK Security Service MI5 said 10,000 staff from every UK government department and from important UK industries have been lured by fake LinkedIn profiles. MI5 said the faked LinkedIn accounts are created and operation by nation-state spy agencies, with an intent to  recruit individuals or gather sensitive information. MI5 released a campaign video called "Think Before You Link" to raise awareness  of the threat. The personal information of 11 million UK Facebook profiles were been found on a hackers website , with the social media giant seemingly dismissing the significance of the data within a statement, " This is old data that was previously reported on in 2019...

The Linux Flaw you can't afford to Ignore (CVE-2021-3156)

Image
Linux and Unix operating systems require regular patching like any IT system, but as security professionals, ethical hackers, and criminal hackers will tell you, regular Linux and Unix patching is often neglected. CVE-2021-3156 sudo Vulnerability Last week (26th January 2021) a new critical rated Linux\Unix vulnerability was made public under  CVE-2021-3156 . Specifically, the vulnerability is within the 'sudo' program, which is an abbreviation of ' superuser do ', well that's how I remember it. Sudo is a powerful and fundamental program found within all Linux and Unix distributions, allowing users to execute programs with the security privileges of another user. A typical use of sudo is where you need to run a program with privilege level (i.e. administrator) access rights. The sudo 'heap overflow' vulnerability was discovered by Qualys researchers, the exploit  allows any unprivileged user to gain root level (i.e. administrative) privileges.   Qualys has p...

Cyber Security Roundup for July 2020

Image
A roundup of UK focused Cyber and Information Security News, Blog Posts, Reports and general Threat Intelligence from the previous calendar month, June 2020. Australian Prime Minister Scott Morrison announced a sophisticated nation-state actor is causing increasing havoc by attacking the country’s government, corporate institutions, and his country's critical infrastructure operators . He said,  “We know it is a sophisticated state-based cyber actor because of the scale and nature of the targeting and the tradecraft used". While Morrison didn't actually name the specific country responsible in his statement, Reuters said its sources confirmed China was the culprit.  Political t ensions have ramped up between Australia and China in recent months after Australia called for an investigation into China’s handling of the COVID-19 pandemic. China then reacted by placing tariffs on Australian exports and banning shipments of beef from Australia . Why am I leading a UK cyber...

Cyber Security Roundup for June 2020

Image
A roundup of UK focused Cyber and Information Security News, Blog Posts, Reports and general Threat Intelligence from the previous calendar month, May 2020. EasyJet's disclosure of a "highly sophisticated cyber-attack", which occurred in January 2020, impacting 9 million of their customers was the biggest cybersecurity story of May 2020 in the UK. Although no details about this 'cyber-attack' were disclosed, other than 2,208 customers had their credit card details accessed.   Using terms like "highly sophisticated" without providing any actual details of the cyberattack makes one think back to when TalkTalk CEO Dido Harding described a cyber-attack as " significant and sustained cyber-attack " in 2015. In TalkTalk's case, that cyber attack turned out to be a bunch of teenage kids taking advantage of a then 10-year-old SQL injection vulnerability.  City A.M. described Dido's responses as "naive", noting when asked if the aff...

Cyber Security Roundup for January 2019

Image
The first month of 2019 was a relatively slow month for cyber security in comparison with the steady stream of cyber attacks and breaches throughout 2018.  On Saturday 26th January, car services and repair outfit Kwik Fit told customers its IT systems had been taken offline due to malware, which disputed its ability to book in car repairs. Kwik Fit didn't provide any details about the malware, but it is fair to speculate that the malware outbreak was likely caused by a general lack of security patching and anti-virus protection as opposed to anything sophisticated. B&Q said it had taken action after a security researcher found and disclosed details of B&Q suspected store thieves online. According to Ctrlbox Information Security, the exposed records included 70,000 offender and incident logs, which included: the first and last names of individuals caught or suspected of stealing goods from stores descriptions of the people involved, their vehicles and other incident-re...
