Words you must never type on social media over devastating ‘sim swap' phone attack that can breach ALL accounts
THERE are some details you just cannot share on social media - or you could be putting yourself at risk of a devastating "SIM swap" attack, experts have warned. In the wake of the M&S cyberattack in April, where SIM swapping is believed to have played a role, consumers have been warned that the breed of attack could also wreak havoc on their own personal lives. 5 5 SIM swapping is a form of fraud that is swiftly on the rise, according to a report published in The Conversation last month, co-authored by computer science professor Alan Woodward and secure systems lecturer Daniel Gardham, both of the University of Surrey. Attacks rose by a whopping 1,055 per cent in 2024, according to the National Fraud Database. It has also allegedly been used in the hacking of former Twitter CEO Jack Dorsey in 2019. "Our mobile phone numbers have become a de facto form of identification, but they can be hijacked for nefarious purposes," the pair wrote. People typically have the same phone number for years - even after changing phones, losing their device, or having it stolen. "When a user buys a new phone, or just a new sim card for a spare device they might have, they might call their service provider to transfer their longstanding mobile number to the new sim card," experts explained. "The problem is that the service provider doesn't know if it is really them calling to transfer the number. "Hence, they launch into a series of questions to make sure they are who they say they are." These security questions are used for all kinds of accounts, and often ask for the same information. For example, "what is your mother's maiden name?", or "...the name of your first pet?" Huge Global Data Breach: 16 Billion Accounts at Risk But if someone else can know the answers to those questions after stalking your social media, it leaves you at risk of not only SIM swap fraud but other forms of hacking. "The rise of social media has made it easier than ever for scammers to piece together what was once considered private information," experts wrote. "Suddenly, someone else can make and receive calls and SMS messages using your number." That means hackers can make calls at your expense. But it's not just your phone number that can be stolen. SIM swapping can be used to breach all your other accounts through the theft of two-factor authentication (2FA) codes. Security experts recommend all consumers have the 2FA tool switched on with all their accounts. 5 Instead of just relying on a password, 2FA adds a second factor - like a code from your phone or biometric data like your fingerprint or face ID. Woodward and Gardham added: "Remember when you created your email, bank account or even online grocery shopping account and you were encouraged to set up two-factor authentication (2FA)? "You listened, but the system set your 'second factor' as your mobile phone number. "You input your username and password, and it asks for a time-limited code that it sends to you as an SMS message." Now, if you have been a victim of SIM swapping - the hackers will receive your security codes instead of you. This could potentially grant them access to all sorts of accounts, from your social media to your banking app. Efforts to improve login security have led to the rise of what are known as passkeys... Which are long sequence of random digits called cryptographic keys that are stored on your device, such as a smartphone or computer. Prof Alan Woodward and lecturer Daniel Gardham, of the University of Surrey It's important to note that even with the risks of SIM swapping, 2FA should still be enabled on all your accounts. In addition to it, however, experts are encouraging the use of passkeys - a passwordless login method that is supposed to be more secure. "Efforts to improve login security have led to the rise of what are known as passkeys," Woodward and Gardham explained. "Which are long sequence of random digits called cryptographic keys that are stored on your device, such as a smartphone or computer." Passkeys are used to log into your online account only when you unlock your phone through your PIN code, fingerprint or face ID. WHAT ARE PASSKEYS? Passkeys are the newer, safer passwords, according to tech companies and security experts. They allow you to log into your accounts using biometrics like your fingerprint or face scan. You can even use your phone's passcode. To sign into a website or app on your phone, all you need to do is unlock your phone. This also works for websites on PCs and laptops. If you're trying to sign into a website on your computer, you just need your phone nearby. You will be prompted to unlock your phone when trying to log into an account on your computer, which will then grant you access on the PC. By using unique credentials tied to your phone or other devices, you make your accounts more resistant to phishing and other password-based attacks. 5 5

Mystery over alleged teen killer's activities at a café just minutes before he was arrested over the alleged murder of Universal Store CEO - as cops scour the business for clues
Bizarre footage has emerged of a teenager at a local café, shortly after he allegedly stabbed Universal Store CEO Greg Josephson to death during a house party at the millionaire's sprawling Brisbane home. A 15-year-old boy has been charged with one count of murder after Mr Josephson was found critically injured at the gathering attended by 30 teenagers on Thursday. Officers arrived at the six-bedroom 1930s Art Deco mansion in Clayfield, in Brisbane 's inner north, just after 8.15pm and found the CEO unresponsive upstairs. Police allege an altercation took place between the teenager and the father-of-three, who are believed to be known to each other. A household item was used in the alleged attack. Winter holidays run from June 28 to July 13 in Queensland, with private schools usually breaking up a few days earlier. CCTV footage from a café near Mr Josephson's mansion showed the alleged killer walking across a patio area while wringing his hands. The teen is understood to have sustained a hand injury in the alleged attack, the Courier Mail reports. He appeared smartly dressed in a button-up shirt and pants as he proceeded to squeeze his way into a narrow rubbish area at the back of the venue. He then appeared to create a barricade by moving several bins in front of him. Police arrested the 15-year-old about 8.15pm after he called triple zero. He was refused police bail and has been taken to hospital. The café has since remained a place of interest, with officers and a dog squad reportedly seen searching the area on Friday afternoon. For almost two decades, Mr Josephson was the director of the Brisbane-based Universal Store, which he established with his brother Michael in 1999. From one store in Carindale, the company has grown to 80 outlets in every state and territory of Australia, as a leader in youth and streetwear fashion with an annual revenue of more than $288million. The Josephson brothers sold the business for $100million in September 2018 to private equity investors Five V Capital, Catalyst Direct Capital Management and BBRC Worldwide, which had previously invested in Bras N Things. Universal Store Holdings was listed on the Australian Securities Exchange in November 2020 and the brand has continued to grow since the Josephson brothers relinquished control almost seven years ago. Mr Josephson and his wife Tamra bought the Clayfield home for $1.91million in 2016. The couple embarked on a major renovation, with Mr Josephson explaining at the time how they had planned to 'create a huge garage with a tennis court above it'. 'We were looking for a big family home and this was in very original condition,' he told the Courier Mail earlier this month. The sprawling Oriel Road property had been on the market for just 43 days when Mr Josephson was allegedly murdered.
