Charities and not-for-profit organisations in Australia are facing an escalating number of cyber threats. In the 2022-23 financial year alone, the Australian Signals Directorate (ASD) received nearly 94,000 cybercrime reports, indicating one report filed approximately every 6 minutes. Recognising this concerning trend, the ASD is urging these entities to enhance their online security measures and stay vigilant.
Due to their limited resources, charities and not-for-profit organisations are increasingly vulnerable to malicious attacks. Such incidents can result in substantial costs, including financial losses, data breaches, reputational damage, loss of trust from donors and beneficiaries, and overall harm to the community they serve.

Not to fear, AUSCERT is here to help! Our members have access to a team of experts who can provide guidance, support, and assistance when incidents arise! An effective cyber security incident response is essential for maintaining organisational objectives by avoiding or limiting the impact of cyber security incidents.

Register for our Incident Response Planning Course to develop the skills needed to write and implement a bespoke incident response plan for your organisation. This course is designed to provide organisations with crucial information and knowledge to execute one of the critical elements of incident response preparation. Our upcoming course is scheduled for 16-17 April from 9am – 12:30pm, with limited places available so register now!

Microsoft announces deprecation of 1024-bit RSA keys in Windows

Author: Bleeping Computer

Microsoft has announced that RSA keys shorter than 2048 bits will soon be deprecated in Windows Transport Layer Security (TLS) to provide increased security.
Rivest–Shamir–Adleman (RSA) is an asymmetric cryptography system that uses pairs of public and private keys to encrypt data, with the strength directly related to the length of the key. The longer these keys, the harder they are to crack.
1024-bit RSA keys have approximately 80 bits of strength, while the 2048-bit key has approximately 112 bits, making the latter four billion times longer to factor. Experts in the field consider 2048-bit keys safe until at least 2030.
