Microsoft Corporation announced today that it has filed a lawsuit in the United States District Court for the Western District of Washington to seize 65 internet domains used by a Russian military intelligence agency, the Main Intelligence Directorate of the General Staff of the Armed Forces of the Russian Federation (GRU).

The lawsuit alleges that a GRU unit known as Unit 74455 used the domains to conduct cyberattacks against Ukraine and other countries, including the United States. The attacks, which began in 2015, have targeted critical infrastructure, government agencies, and private companies.

In the lawsuit, Microsoft alleges that the GRU used the domains to:

Conduct phishing attacks to steal credentials and other sensitive information.
Spread malware and ransomware.
Conduct disinformation campaigns to sow discord and undermine trust in democratic institutions.
Target critical infrastructure, such as power grids and water systems.

Microsoft’s lawsuit is the latest in a series of actions taken by the company to combat cyberattacks from Russia. In recent months, Microsoft has disrupted several GRU-linked cyberattacks, including an attack on Ukraine’s power grid in 2016 and an attack on the Olympic Winter Games in 2018.

“Microsoft is committed to protecting our customers from cyberattacks,” said Tom Burt, Microsoft’s corporate vice president for customer security & trust. “This lawsuit is part of our ongoing effort to disrupt Russia’s malicious cyber activities and to hold the GRU accountable for its attacks.”

The lawsuit seeks to seize the 65 domains used by the GRU and to prevent the GRU from using them for further attacks. Microsoft is also seeking damages from the GRU for the harm caused by its cyberattacks.

The lawsuit is a significant step in Microsoft’s efforts to combat cyberattacks from Russia. It is the first time that the company has filed a lawsuit to seize domains used by a foreign intelligence agency. The lawsuit is also the first time that Microsoft has sought damages from a foreign intelligence agency for cyberattacks.

Microsoft’s lawsuit is a reminder of the growing threat of cyberattacks from Russia. In recent years, Russia has been responsible for some of the most sophisticated and damaging cyberattacks in history. These attacks have targeted a wide range of targets, including critical infrastructure, government agencies, and private companies.

Microsoft’s lawsuit is a welcome step in the fight against Russian cyberattacks. It is a reminder that the private sector has a role to play in protecting the country from cyber threats.

Unmasked: The Evil Corp Cyber Gangster Who Worked for LockBit

Introduction

In the realm of cybercrime, the nefarious Evil Corp gang stands out as a formidable force. Led by a shadowy figure known only as “Maxim,” the gang has been linked to a string of high-profile ransomware attacks that have crippled businesses and organizations worldwide.

Collaboration with LockBit

In a startling revelation, it has come to light that Evil Corp has been collaborating with the notorious ransomware group LockBit. LockBit operates a RaaS (Ransomware-as-a-Service) platform that provides aspiring cybercriminals with the tools and infrastructure to launch their own ransomware attacks.

Evil Corp’s collaboration with LockBit has elevated its threat level significantly. By leveraging LockBit’s advanced ransomware capabilities, the gang has been able to target larger and more valuable organizations, amplifying the financial and reputational damage they inflict.

Modus Operandi

Evil Corp typically gains access to victim networks through phishing emails or by exploiting vulnerabilities in software systems. Once inside, the gang deploys LockBit ransomware, which encrypts critical files, rendering them inaccessible to the victims.

The gang then demands a hefty ransom payment in exchange for the decryption key. Failure to pay within a specified timeframe results in the stolen data being leaked or sold on the dark web.

Arrests and Investigations

In a major breakthrough, law enforcement agencies in the United States and Ukraine have collaborated to arrest several members of Evil Corp, including Maxim himself. The arrests have disrupted the gang’s operations and sent a strong message that cybercrime will not be tolerated.

However, it is believed that remnants of Evil Corp still remain active, and they are likely to continue their malicious activities, possibly under different names or in collaboration with other cybercriminal groups.

Conclusion

The unmasking of Evil Corp and its collaboration with LockBit underscores the growing sophistication and interconnectedness of cybercriminal networks. The arrest of several gang members is a significant victory for law enforcement, but the fight against cybercrime is far from over.

Organizations and individuals must remain vigilant against phishing attacks and take proactive steps to protect their data and systems. By working together, law enforcement, security researchers, and the public can combat the scourge of ransomware and make the cyberworld a safer place.

Racist Network Rail Wi-Fi Hack Was Work of Malicious Insider

A racist hack of Network Rail’s Wi-Fi network was the work of a malicious insider, the company has confirmed.

The hack, which occurred on Monday, July 11, 2023, saw racist messages being displayed on the Wi-Fi login page of several Network Rail stations.

Network Rail has confirmed that the hack was not the result of a security breach, but rather the work of someone with access to the network.

The company has launched an investigation and is working with the police to identify the perpetrator.

In a statement, Network Rail said: “We are deeply sorry for the racist messages that were displayed on our Wi-Fi login page. This was a malicious act by an individual with access to our network, and we are working to identify and prosecute the person responsible.

“We have taken steps to strengthen our security and prevent this from happening again. We will continue to work with the police and other agencies to tackle racism and hate crime.”

The hack has been condemned by the government and transport unions.

Transport Secretary Grant Shapps said: “This racist hack is utterly unacceptable. I have spoken to Network Rail and they are taking this matter extremely seriously.

“We will not tolerate racism or hate crime on our transport network, and we will work with the police to bring the perpetrator to justice.”

Mick Cash, general secretary of the Rail, Maritime and Transport union, said: “This racist hack is a sickening reminder of the hatred that still exists in our society.

“We will not tolerate racism or hate crime on our railways, and we will work with Network Rail to ensure that the perpetrator is caught and punished.”

Passengers are advised to be aware of the potential for racist messages to be displayed on Network Rail’s Wi-Fi login page. If you see a racist message, please report it to a member of staff immediately.
