color: #000000;\">Medusa&#8217;s group was first formed in 2021 and they initially conducted all attacks themselves. In 2022, the group moved to a <a href=\"https:\/\/threatcop.com\/blog\/ransomware-as-a-service\/\">ransomware-as-a-service (RaaS)<\/a> model in which attackers or a group of affiliate hackers can take care of attacks while the core group takes care of ransom negotiation and collections. The group could originally conduct all attacks themselves, so there is now a large network of affiliates working on behalf of Medusa. They simply handle the negotiations and payments to affiliates; there is more separation between the actors.\u00a0<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">Medusa should not be mistaken for the other threats of a similar name. This is a separate ransomware strain and is not part of a larger family; it has created its own unique malware infrastructure.<\/span><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Medusa_Ransomware_Gang_Phishing_Campaigns_and_Entry_Methods\"><\/span><span style=\"color: #000000;\"><b>Medusa Ransomware Gang Phishing Campaigns and Entry Methods<\/b><\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">Phishing is the typical method of gaining initial access to a victim&#8217;s systems in this <a href=\"https:\/\/threatcop.com\/blog\/ransomware-attacks\/\">type of ransomware attack<\/a>. Employees are issued emails that appear to be from trusted contacts or internal departments in which they work.<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"color: #000000;\"><span style=\"font-weight: 400;\">These emails often contain some malicious link or attachment and when your employee clicks it, it will install malware on their machine. <\/span><span style=\"font-weight: 400;\">The group will also purchase stolen login credentials obtained from initial access brokers, which allow them to log in directly to business systems to avoid detection.<\/span><\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;

There are two things to note here: first, this is a wake-up call for chief information security officers (CISOs) to step up their prevention activities; second, it is a strong reminder for employees to think twice before clicking, as just one negative click can lead to a large breach.<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">Preventing threats involves preparation: according to general downloads of CISO sites, patch your systems, educate your team, back up your data, and have a legitimate supporting response plan in place.
