“Sic Transit Gloria Mundi”, and so our perception of a secure system does erode away with time. Well, systems do not form security cracks over time but there is an enormous amount of effort being made to find them and then patch them. So don’t let your systems security fade: keep the patches up to date.


Microsoft Outlook for Android Bug Opens Door to XSS

Users of the Microsoft Outlook for Android app should update their apps to avoid a range of attacks.
The bug (CVE-2019-1460) would allow an attacker to perform cross-site scripting attacks on the affected systems and run scripts in the security context of the current user, according to Microsoft’s advisory on the bug. XSS occurs when malicious parties inject client-side scripts into web pages, which trick the unsuspecting user’s browser into thinking that the script came from a trusted source.

An infamous vigilante hacker known for their hits on surveillance companies is launching a new kind of bug bounty to reward hacktivists who do public interest hacks and leaks.
In their new manifesto, Phineas Fisher also claimed to have hacked an offshore bank and called on other hacktivists to join in the fight against inequality and capitalism. The hacker said that in 2016 they hacked the Cayman Bank and Trust Company from the Isle of Man, an island between the UK and Northern Island. The hacker said they were able to steal money, documents, and emails from the bank.
The hacker shared the stolen documents and emails from the bank to the leaking website Distributed Denial of Secrets, run by journalist and activist Emma Best, who said they uploaded 640,000 emails, in what is “the most detailed look at international banking that the public will have ever had access to.”

Get ahead of the cybersecurity curve

Experienced cybersecurity leaders are beginning to call for a move from reactive detection to proactive prevention. It’s clear that the need to get ahead of the cybersecurity curve is real.
Over the past decade, experts talked about the number of days that malware is in your system, and now the discussion is fast becoming how many seconds you have between detection and disaster. There is no longer time to call the boss, check your files or phone a friend. Victims are literally watching their systems being taken over, and they are powerless to stop it despite massive budgets and plans. Clearly, spending on an arms race with dollars, people and technology is not an effective long-term solution. We need a different approach.
Enter proactive prevention, the concept behind this move toward flipping the script and finally getting ahead of our adversaries.

Students in the Digital Analysis course at the ANU will be forced to re-take an exam, potentially delaying their graduation, after the university confirmed a data leak last week.
“The need for a class to re-sit an exam is extremely rare, and is only undertaken when absolutely required,” an ANU spokesperson said after security protocols successfully identified that a breach had occurred.
