1. Data Breaches

CISA and NSA highlights RMM phishing, Zack Investment Research breach effect 7 years of signups, Yandex claim ex-employee for stealing 45GB of source code

  1. CISA, NSA, and MS-ISAC released a joint advisory warning about the malicious use of legitimate remote monitoring and management (RMM) software (ScreenConnect and AnyDesk) used in a phishing scam to steal money from bank accounts. The authoring organizations have warned network defenders to apply the recommended mitigations to protect against such malicious use of RMM software. Source:
  2. Zacks Investment Research reported a data breach on December 28, 2022, where an unknown third-party had gained unauthorized access to certain customer records. The data breach affected Zacks Elite customers who had signed up between November 1999 and February 2005, and included their name, address, phone number, email address, and password. Zacks has taken immediate measures to enhance its security and is continuing its investigation to evaluate additional measures to protect customer information. Source:
  3. Yandex, the Russian technology company, had a source code repository allegedly stolen by a former employee and leaked on a hacking forum as a torrent. The leak consists of 44.7 GB of files stolen from the company in July 2022 and contains all of the company's source code besides anti-spam rules. Yandex has blamed the leak on the former employee and denied any hacks. Source:

2. Research

Quantum computer factorized RSA-2048, defenders hacked scammers, DMARC and subdomain takeover

  1. Digitized-Counterdiabatic Quantum Factorization (DCQF) Algorithm: A recent study performed by the Quantinuum team has proposed a non-hybrid approach to tackle the integer factorization problem on a quantum computer. The team compared their approach to Bao Yan et al.'s algorithm which combined Babai's algorithm with the quantum approximate optimization algorithm (QAOA). The new DCQF approach outperforms QAOA techniques in solving the closest vector problem on a lattice, which reduces the problem to an optimization problem. The report explores the possibility of factoring larger numbers using compressed algorithms in quantum computers, and the potential of using analog or digital-analog encoding schemes towards factoring RSA-2048 in the NISQ era.

  2. SBI Scam: An incident was reported where a scam message was being circulated in the name of SBI Reward Points. Upon investigating the website, the admin panel was found to be vulnerable to SQL Injection on its login page. This allowed attackers to gain access to the panel and potentially steal sensitive information. Source:
  3. Subdomain Takeover and Email Security: A subdomain takeover is when an attacker gains control over a subdomain of a target domain by hosting their own content for it. This could result in phishing or theft of cookies from impersonated web pages. This article highlights the consequences of subdomain takeover in email security, as well as how attackers can use subdomain takeovers to craft convincing phishing emails. Source:
