Attackers were able to compromise customers’ personal data by targeting the Accellion FTA server of a third-party vendor.

Morgan Stanley has confirmed a data breach in which attackers were able to access personal information belonging to customers by targeting a vulnerability in the Accellion FTA server.

The server belonged to Guidehouse, a vendor that provides account maintenance services to Morgan Stanley’s StockPlan Connect business, the bank said in a letter disclosing the incident. Attackers were able to access participant data, including name, last known address, birth date, Social Security number, and corporate company name. The data compromised did not include passwords that could be used to access financial accounts.

Morgan Stanley said the compromised files were encrypted; however, attackers were able to obtain the decryption key during the breach.

This makes the bank one of many organizations affected by the vulnerability in the Accellion FTA server, an issue disclosed earlier this year. Following Accellion’s January announcement, several businesses experienced data theft and subsequent extortion attempts.

While Guidehouse patched the vulnerability within five days of its availability, the attacker was able to access the data around that time, officials said. The vendor discovered the attack in March 2021 and learned it affected Morgan Stanley in May. It says the delay was due to the trouble in determining which files were stored in the Accellion FTA server when it was exposed.

The Kaseya ransomware attack is believed to have been down to an authentication bypass. Yes, ransomware needs to be on your radar — but good authentication practices are also imperative.

Last Friday, just before the extended American Independence Day holiday, it was announced that Kaseya, an American software company, was hacked. The malicious actors were able to distribute ransomware by exploiting several vulnerabilities in Kaseya’s Vector Signal Analysis (VSA) software, which gave the attackers the ability to infect multiple organizations via what is known as a supply chain attack.

From Omdia’s perspective, supply chain cybersecurity is hugely complex, and many organizations have not paid it sufficient attention. Organizations can have hundreds or even thousands of suppliers digitally connected, and the risks are rarely quantified, and even when they are, it is frequently a manual process.

The attack is suspected to be the work of REvil (Ransomware Evil; also known as Sodinokibi), a ransomware gang with relative impunity operating out of Russia, where authorities frequently turn a blind eye to such gangs. REvil has demanded $70 million in Bitcoin in return for a universal decryptor that it claims will unlock the files of all victims. It is believed that REvil used an authentication bypass in the Web interface of Kaseya VSA to gain an authenticated session, upload the original payload, and then execute commands via SQL injection.

The attack highlights growing concern in the cybersecurity world about supply chain attacks; there are hundreds or thousands of potential victims by attacking a single supplier. The number of companies affected by this attack is unclear and will likely increase. For example, security company Huntress, which was one of the earliest sources to detect the attack, estimates “30 MSPs across the US, AUS, EU, and LATAM” have been breached and that over 1,000 organizations have been infected with ransomware as a result. Moreover, as a result of this attack, around 500 Coop stores in Sweden were also forced to shut.

Rest assured, this isn’t the last of the supply chain attacks we will see this year, or perhaps even this month. Recommendations from the USA’s Cybersecurity and Infrastructure Security Agency (CISA) for mitigating this particular attack include getting VSA servers offline, enforce multifactor authentication (MFA) as soon as possible, ensure that backups are in order and stored in air-gapped systems, and that remote monitoring and management tools be limited to communication among known IP address pairs.

Organizations must be less trusting of their supply chains and increase focus on understanding and reducing the associated risks.
