The group, which Microsoft has dubbed Hafnium, has aimed to gain information from defense contractors, schools and other entities in the U.S., according to a blog post by Microsoft VP Tom Burt. enabling affected victims to grow exponentially from there. [21] The first breach of a Microsoft Exchange Server instance was observed by cybersecurity company Volexity on 6 January 2021. G0087 : APT39 : APT39 has used various tools to steal files from the compromised host. U.S. Govt to Control Export of Cybersecurity Items to Regions with Despotic Practices. Lucian Constantin is a senior writer at CSO, covering information security, privacy, and data protection. 0 Since then many cybercrime groups have adopted sophisticated techniques that often put them on par with nation-state cyberespionage actors. We want to hear from you. Copyright 2020 IDG Communications, Inc. %%EOF "[18] In the past, Microsoft Exchange has been attacked by multiple nation-state groups. SMBS GUIDE TO MARKETING: STAND OUT AND BOOST SALES DURING THE HOLIDAYS. To avoid detection, attackers used temporary file replacement techniques to remotely execute their tools. With that, a second vulnerability can then be exploited, escalating that user access to administrator privileges. G0032 : Lazarus Group "After an initial dormant period of up to two weeks, it retrieves and executes commands, called 'Jobs,' that include the ability to transfer files, execute files, profile the system, reboot the machine, and disable system services," the FireEye analysts said. Second, it would create what's called a web shell to control the compromised server remotely. Microsoft also took the unusual step of issuing a patch for the 2010 edition, even though support for it ended in October. That was the first condition. Attackers typically install a backdoor that allows the attacker full access to impacted servers even if the server is later updated to no longer be vulnerable to the original exploits. [29], Through the web shell installed by attackers, commands can be run remotely. IT departments are working on applying the patches, but that takes time and the vulnerability is still widespread. ", While software that is deployed in organizations might undergo security reviews to understand if their developers have good security practices in the sense of patching product vulnerabilities that might get exploited, organizations don't think about how that software could impact their infrastructure if its update mechanism is compromised, Kennedy says. That wasn't an attack where the software developer itself, Microsoft, was compromised, but the attackers exploited a vulnerability in the Windows Update file checking demonstrating that software update mechanisms can be exploited to great effect. From a ransomware perspective, if they simultaneously hit all the organizations that had SolarWinds Orion installed, they could have encrypted a large percentage of the world's infrastructure and made off with enough money that they wouldn't have ever had to work again. Back in 2012, researchers discovered that the attackers behind the Flame cyberespionage malware used a cryptographic attack against the MD5 file hashing protocol to make their malware appear as if it was legitimately signed by Microsoft and distribute it through the Windows Update mechanism to targets. 101 0 obj <>/Filter/FlateDecode/ID[<9EF7FCA3FD9E3448B167CF924F04CDCC>]/Index[68 62]/Info 67 0 R/Length 144/Prev 192283/Root 69 0 R/Size 130/Type/XRef/W[1 3 1]>>stream SolarWinds has announced it is facing US Securities and Exchange Commission (SEC) enforcement action over the software company's massive data breach in 2020..

SolarWinds advises customers to upgrade to Orion Platform version 2020.2.1 HF 1 as soon as possible to ensure they are running a clean version of the product. "Because we are aware of active exploits of related vulnerabilities in the wild (limited targeted attacks), our recommendation is toinstall these updates immediatelyto protect against these attacks," Microsoft said in a blog post. [26], The attacks came shortly after the 2020 United States federal government data breach, which also saw the compromising of Microsoft's Outlook web app and supply chain. "The fact that attackers were potentially on the organization's network over a year before they were discovered signals this could be true. Still, the disclosure comes less than three months after U.S. government agencies and companies said they had found malicious content in updates to Orion software from information-technology company SolarWinds in their networks. One week ago, Microsoft disclosed that Chinese hackers were gaining access to organizations' email accounts through vulnerabilities in its Exchange Server email software and issued security patches. We anticipate there are additional victims in other countries and verticals. Kennedy believes it should start with software developers thinking more about how to protect their code integrity at all times but also to think of ways to minimize risks to customers when architecting their products. "Organizations need to harden their networks against this using access encryption and segmentation. Later that day, GitHub removed the code as it "contains proof of concept code for a recently disclosed vulnerability that is being actively exploited". On March 2, Microsoft said there were vulnerabilities in its Exchange Server mail and calendar software for corporate and government data centers. The attackers kept their malware footprint very low, preferring to steal and use credentials to perform lateral movement through the network and establish legitimate remote access. Advanced Intel detected one of Acer's Microsoft Exchange servers first being targeted on 5 March 2021. It's good security practice in general to create as much complexity as possible for an adversary so that even if they're successful and the code you're running has been compromised, it's much harder for them to get access to the objectives that they need.". The software builds for Orion versions 2019.4 HF 5 through 2020.2.1 that were released between March 2020 and June 2020 might have contained a trojanized component. It's likely that the number of software supply-chain attacks will increase in the future, especially as other attackers see how successful and wide ranging they can be. The backdoor was used to deliver a lightweight malware dropper that has never been seen before and which FireEye has dubbed TEARDROP. endstream endobj startxref "They probably know their sophistication level will need to be increased a bit for these types of attacks, but it's not something that is too far of a stretch, given the progression we're seeing from ransomware groups and how much money they're investing in development. Got a confidential news tip? That, however, was just the tip of the Companies, as users of software, should also start thinking about applying zero-trust networking principles and role-based access controls not just to users, but also to applications and servers. First notice of a problem came via cybersecurity company FireEye, one of a number of well-known security companies that were victims in the SolarWinds compromise. This is some of the best operational security exhibited by a threat actor that FireEye has ever observed, being focused on detection evasion and leveraging existing trust relationships. As of 9March2021[update], it was estimated that 250,000 servers fell victim to the attacks, including servers belonging to around 30,000 organizations in the United States, 7,000 servers in the United Kingdom,[8] as well as the European Banking Authority, the Norwegian Parliament, and Chile's Commission for the Financial Market (CMF). Hackers managed to hack into the Onion and added malicious code which was In a recent 8-K filing with the SEC, the company said it reached an agreement with shareholders, who originally sued SolarWinds over claims they were misled about the Universidad de Guadalajara. [3] On 15 March, Microsoft released a one-click PowerShell tool, The Exchange On-Premises Mitigation Tool, which installs the specific updates protecting against the threat, runs a malware scan which also detects installed web shells, and removes threats that were detected; this is recommended as a temporary mitigation measure, as it does not install other available updates. This means they modified a legitimate utility on the targeted system with their malicious one, executed it, and then replaced it back with the legitimate one. Cybercrime could cost $10.5 trillion dollars by 2025, according to Cybersecurity Ventures, A cybersecurity stock analyst weighs in on the Microsoft email hack. "Additionally, defenders can monitor existing scheduled tasks for temporary updates, using frequency analysis to identify anomalous modification of tasks. The US Department of Homeland Security has also issued an emergency directive to government organizations to check their networks for the presence of the trojanized component and report back. Damian Williams, the United States Attorney for the Southern District of New York, and Michael J. Driscoll, Assistant Director in Charge of the New York Office of the Federal Bureau of Investigation (FBI), announced today the arrest of FOSTER COOLEY for charges in connection with a scheme to conduct cyber intrusions targeting a New York Just as not every user or device should be able to access any application or server on the network, not every server or application should be able to talk to other servers and applications on the network. WebDHSs decision to direct the Cyber Safety Review Board to study the Lapsus$ hacker ring is drawing a mixture of criticism and praise from the cybersecurity community. [16] Microsoft stated: "There is no guarantee that paying the ransom will give you access to your files. The backdoor uses multiple obfuscated blocklists to identify forensic and anti-virus tools running as processes, services, and drivers.". Even though FireEye did not name the group of attackers responsible, the Washington Post reports it is APT29 or Cozy Bear, the hacking arm of Russia's foreign intelligence service, the SVR. Microsoft's big email hack: What happened, who did it, and why it matters Published Tue, Mar 9 2021 6:20 PM EST Updated Tue, Mar 9 2021 8:12 PM EST Jordan Novet @jordannovet "[22][30], In a July 19, 2021 joint statement, the US, UK, EU, NATO, and other Western nations accused the Ministry of State Security (MSS) of perpetrating the Exchange breach, along with other cyberattacks, "attributing with a high degree of confidence that malicious cyber actors affiliated with PRCs MSS conducted cyber espionage operations utilizing the zero-day vulnerabilities in Microsoft Exchange Server disclosed in early March 2021. [26][50], The attack was discovered after attackers were discovered downloading all emails belonging to specific users on separate corporate Exchange servers. WebThe attacks entail the use of different malware such as ERMAC , Erbium , Aurora , and Laplas , according to a ThreatFabric report shared with The Hacker News. Satya Nadella, chief executive officer of Microsoft Corp., pauses during a Bloomberg event on the opening day of the World Economic Forum (WEF) in Davos, Switzerland, on Tuesday, Jan. 21, 2020. Hack-and-leak is the new black (and bleak) Ransomware groups have resorted to this tactic as a way to apply pressure on victims, but APTs may leverage it for purely disruptive ends. The SolarWinds hack exposed government and enterprise networks to hackers through a routine maintenance update to the company's Orion IT management software. Escuela Militar de Aviacin No. FireEye has notified all entities we are aware of being affected.". %PDF-1.6 % [9][10][11][12][13][14], On 2 March 2021, Microsoft released updates for Microsoft Exchange Server 2010, 2013, 2016 and 2019 to patch the exploit; this does not retroactively undo damage or remove any backdoors installed by attackers. REvil has demanded a $50 million U.S. dollar ransom, claiming if this is paid they would "provide a decryptor, a vulnerability report, and the deletion of stolen files", and stating that the ransom would double to $100 million U.S. dollars if not paid on 28 March 2021. "The malware masquerades its network traffic as the Orion Improvement Program (OIP) protocol and stores reconnaissance results within legitimate plugin configuration files allowing it to blend in with legitimate SolarWinds activity. To others, it was amusing. "The best protection is to apply updates as soon as possible across all impacted systems. "We are likely to see more action like this in the future, particularly as most organizations are not still securing and segmenting their network access properly," O'Toole warned. [27], Microsoft said that the attack was initially perpetrated by the Hafnium, a Chinese state-sponsored hacking group (advanced persistent threat) that operates out of China. The hack went undetected for months before the victims discovered vast amounts of their data had "[53], On 12 March 2021, Microsoft Security Intelligence announced "a new family of ransomware" called DearCry being deployed to the servers that had been initially infected, encrypting device contents, making servers unusable and demanding payment to recover files. [45] On 11 March 2021, Norway's parliament, the Storting, reported being a victim of the hack, stating that "data has been extracted. WebAdversaries may communicate using application layer protocols associated with web traffic to avoid detection/network filtering by blending in with existing traffic. [15] On 11 March 2021, Check Point Research revealed that in the prior 24 hours "the number of exploitation attempts on organizations it tracks tripled every two to three hours. [16] On 22 March 2021, Microsoft announced that in 92% of Exchange servers the exploit has been either patched or mitigated. 129 0 obj <>stream Among other things, attackers installed and used software to take email data, Microsoft said. "[31][32][33][34], Hackers took advantage of four separate zero-day vulnerabilities to compromise Microsoft Exchange servers' Outlook Web Access (OWA),[2] giving them access to victims' entire servers and networks as well as to emails and calendar invitations,[4] only at first requiring the address of the server, which can be directly targeted or obtained by mass-scanning for vulnerable servers; the attacker then uses two exploits, the first allowing an attacker to connect to the server and falsely authenticate as a standard user. [55], On 2 March 2021, the Microsoft Security Response Center (MSRC) publicly posted an out-of-band Common Vulnerabilities and Exposures (CVE) release, urging its clients to patch their Exchange servers to address a number of critical vulnerabilities. [52], Security company ESET identified "at least 10" advanced persistent threat groups compromising IT, cybersecurity, energy, software development, public utility, real estate, telecommunications and engineering businesses, as well as Middle Eastern and South American governmental agencies. BERNIE SANDERS IS OFTEN CALLED A LIBERAL. So, I definitely think that we can see this with other types of groups [not just nation states] for sure.". The assault against Microsoft Exchange is 1,000 times more devastating than the SolarWinds attack. The Colonial Pipeline carries gasoline, diesel and jet fuel from Texas to as far away as New York.About 45% of all fuel consumed on the East Coast arrives via the pipeline system. The SolarWinds hack, an attack on Microsoft Exchange that affected millions around the world, and a ransomware attack on Colonial Pipeline (resolved only with the payment of $4.4 million to get the system up and running again) all demonstrate the far-reaching ramifications of cyber-vulnerabilities. WebRansomware Operators Leverage Financial Events Like M&A to Pressurize Victims: FBI. The incident highlights the severe impact software supply chain attacks can have and the unfortunate fact that most organizations are woefully unprepared to prevent and detect such threats.
