1. Hundreds of SPAR shops in the UK were impacted by a cyber attack.

Approximately 330 SPAR shops in northern England face severe operational problems following a weekend cyber attack, forcing many stores to close or switch to cash-only payments. Although it has not been confirmed as a ransomware attack just yet, the incident shows clear signs of a ransomware attack. UK’s national cybersecurity centre also released a statement to inform consumers that the agency is aware of the situation and working on evaluating the incident.

2. Google has taken action against the Glupteba botnet and filed a lawsuit against operators.

Google’s Threat Analysis Group has disrupted the blockchain-enabled botnet Glupteba, which is made up of around 1 million compromised Windows and IoT devices. Currently, Glupteba spreads via fake pirate software, fake YouTube videos, malicious documents, traffic distribution systems and more. Googles Threat Analysis Group disrupted critical command-and-control infrastructure, so those operating Glupteba should no longer have control of their botnet. Google also filed a lawsuit against the botnet’s operators.

3. Attackers stole $200 million worth of Cryptocurrency tokens from BitMart Exchange.

Cryptocurrency trading platform BitMart has disclosed a “large-scale security breach” that it blamed on a stolen private key, resulting in the theft of more than $150 million in various cryptocurrencies. The breach is said to have impacted two of its hot wallets on the Ethereum blockchain and the Binance smart chain. The incident is the latest in a wave of hacks that have targeted cryptocurrency platforms such as PolyNetwork, Cream Finance, Liquid, and bZx.
