A hacker posted nearly 10 billion passwords online- likely the biggest leak ever

By Hindustan Times

This could be the largest such compilation of leaked passwords ever and the file contains passwords compromised in both recent and old data breaches.

A file containing almost 10 billion passwords was reportedly posted on an online hacking forum. This could be the largest such compilation of leaked passwords ever and the file contains passwords compromised in both recent and old data breaches all over the world, Semafor reported. Owing to this, there could be an increased chance of credential stuffing attacks in which one compromised password used for a user’s account can be reused by a hacker to break into another account.

The report claimed that not all the passwords in the file appeared to be new which means that they have been leaked previously and this increases the chance of “credential stuffing.” As per the practice, a bad actor can take a user’s known password and try to reuse it to break into other accounts in their name, Cybernews, a cybersecurity-focused news outlet, explained.

This comes as the number of cyberattacks has more than doubled since 2020, an International Monetary Fund report estimated. The financial sector has experienced more than 20,000 attacks in the last two decades, the IMF noted while the healthcare sector is also an appealing target, The Lancet said.

The 10 billion passwords included in a file uploaded by a user named ObamaCare are not all new, Cybernews said.

Cybersecurity specialists told Forbes that the actual number of passwords in this compilation doesn’t increase the threat capabilities of bad actors but the scale highlights glaring holes in online security. One analyst said, “I know this might sound funny, but what’s an extra 1.5 billion passwords?” Forbes also reported that the file may actually turn out to be useless because of its huge size.

Why remote desktop tools are facing an onslaught of cyber threats

By Solomon Klappholz, IT Pro Hackers are increasingly targeting remote desktop tools in their attacks, new research reveals, prompting warnings for enterprises globally In the era of hybrid work, remote desktop tools have become vital business enablers, but due to their pervasiveness on corporate networks they have become a popular entry point for cyber criminals. If successfully exploited, remote access tools can provide hackers with a direct pathway into a system or network, and once access is gained attackers can move laterally within the network, escalating privileges and maintaining persistence. In an investigation into which remote desktop tools are targeted the most, Jonathan Tanner, senior security researcher at Barracuda Networks, explained that remote desktop software poses a particular challenge to IT teams to secure. “Among the security challenges facing IT teams implementing remote desktop software is that there are many different tools available, each using different and

Ransomware gang starts leaking alleged stolen Change Healthcare data

By Lawrence Abrams,  Bleeping Computer The RansomHub extortion gang has begun leaking what they claim is corporate and patient data stolen from United Health subsidiary Change Healthcare in what has been a long and convoluted extortion process for the company. In February, Change Healthcare suffered a cyberattack that caused massive disruption to the US healthcare system , preventing pharmacies and doctors from billing or sending claims to insurance companies. The attack was ultimately linked to the BlackCat / ALPHV ransomware operation, who later said they stole 6 TB of data during the attack . After facing increased pressure from law enforcement, the BlackCat gang shut down their operation . This occurred amid claims they were pulling an exit scam by stealing a $22 million Change Healthcare ransom payment from the affiliate who conducted the attack. While Change Healthcare has declined to comment on whether it has paid a ransom, the affiliate known as "Notchy" said they

Notepad++ wants your help in "parasite website" shutdown

By Ax Sharma,  Bleeping Computer The Notepad++ project is seeking the public's help in taking down a copycat website that closely impersonates Notepad++ but is not affiliated with the project. Although, at the time of writing, the lookalike website takes visitors to the official Notepad++ downloads page, there is some concern that it could pose security threats—for example, if it starts pushing malicious releases or spam someday either deliberately or as a result of a hijack. The lookalike website appears prominently in search results
