Stay Vigilant… 5 Techniques Bad Guys are Using to Breach Your IT

/0 Comments/in /by

While we all know security is important, sometimes day-to-day operations overwhelm our good intentions to keep up with fast-moving technology threats. Staying safe means being continually aware and taking precautions against the more common techniques bad guys are using to breach businesses every day:

1. Spoofing – Email spoofing is when the sender address is forged to make it appear that their email comes from a trusted source, such as your bank. The email can send you to a bogus website where your account details can be stolen. Or it appears to come from inside your own organization, asking you to change your password or confirm your details.

2. Phishing – Often posing as a request for data from a trusted source, this attack is launched via email and asks users to click on a link. Over time, phishing has evolved to include Spear Phishing (targeted attempts highly personalized for a specific individual) and Whaling (phishing scams that target high-profile users and decision makers).

3. Hijacking – This attack changes a computer’s settings to either ignore DNS or use a DNS server that is controlled by malicious hackers. The attackers then redirect communication to fraudulent sites. Website hijacking is commonly used to redirect users to fake login pages for banks and other online services in order to steal their login credentials. It can also be used to redirect security sites to non-existent servers to prevent affected users from updating their security software.

4. Malware Insertion – This refers to a variety of cyber threats including Trojans, viruses and worms which typically steal data or destroy key computer functions; usually introduced through email attachments, website visits, software downloads, or operating system vulnerabilities.

5. Ransomware – This is a specific type of malware that requires some sort of ransom payment to either remove it or to retrieve files that had been encrypted. Ransomware has been around for a long time, but it made news in recent years when payments started to be demanded in Bitcoin, making this activity virtually risk-free for cyber criminals.

Ransomware Attacks Scale Up As Hackers Go After Remote Workers

/0 Comments/in /by

While the switch to home working has allowed many organizations and employees to remain productive, it has also brought additional risk as IT and security teams try to deal with overlapping personal and corporate networks.

Ransomware attacks soared during the first half of 2020, as cyber criminals looked to spread their file-encrypting malware as millions of people shifted to work from home.

According to an analysis of collected malicious activity published in Skybox Security’s 2020 Vulnerability and Threat Trends Report, ransomware has proliferated, with a 72% increase in new file-encrypting malware.

Security vulnerabilities in remote-desktop protocols – combined with the use of weak passwords by staff – have provided cyber attackers with easy access into many IT networks.

Home workers who have not been provided with clear cybersecurity training are even more vulnerable, and smart hackers know that IT teams are already bogged down trying to support remote working.

To protect against ransomware attacks during the pandemic – and beyond – it’s vital to close any vulnerabilities that could be exploited by hackers. This includes having a full view of all connected corporate IT assets so gaps can be identified and remediated.
