Confluence servers hacked to install malware

Cybercriminals are now exploiting a vulnerability in Confluence servers to install cryptojacking malware. According to a report by Trend Micro, the vulnerability has been well documented in the past. However, at the time, it was being used to target victims with DDoS attacks.

Confluence is a widely popular planning and collaboration software developed by the Australian software giant, Atlassian. Trend Micro reported that it had noticed one of the vulnerabilities, CVE-2019-3396, in April, a month after Atlassian published an advisory covering the same. CVE-2019-3396 is a template injection in the Widget Connector that allows cybercriminals to execute code remotely on their victims’ machines.

The vulnerability was first used for a DDoS attack in Romania. However, the cybersecurity and analytics company revealed that hackers are now using it to install a Monero crypto miner that comes with a rootkit. The rootkit serves to hide the malware’s network activity. It also shows false CPU usage on the affected machine, misleading the user and further concealing the mining process. The report further revealed that the rootkit re-installs the malware should the victim manage to remove it.

The attack begins by sending a command to download a shell script hosted on Pastebin, an online content hosting service where users store plain text for a set period of time. The malware then kills off some of the processes running on the host machine before downloading other resources, also from Pastebin.

The vulnerability mainly targets older versions of Confluence, with Atlassian urging its users to download patched versions of Confluence Server and Data Center to protect themselves.

In recent times, cryptojacking has become increasingly popular with cybercriminals. The tactics are also advancing, with the criminals seeking to stay ahead of the security experts. As we reported recently, a new malware that targets Linux servers has been modified to shut down other crypto miners in the host’s system. Known as Shellbot, the malware uses the SSH brute force technique to infect servers that are connected to the internet and that have a weak password.

Bank details of Bernard Matthews employees stolen

A suspected cyber-attack "potentially compromised" the bank account details of 200 workers at Bernard Matthews.

The turkey producer has made staff aware of the suspected hack.

The Norfolk-based company said it was alerted by its bank on 22 January, as first reported in the EDP.

A spokesman said: “After being first alerted by our bank, we reported the incident to the relevant authorities and put in place extra security measures, as well as offering additional security advice to those affected.” "We continue to monitor the situation but we are not aware colleagues have been affected any further," he added.

The person or group behind the hack is unknown.

Bernard Matthews employs 3,000 people across East Anglia. The company is a major employer in Norfolk and Suffolk, including at its plant at Holton, near Halesworth, and its headquarters at Great Witchingham.
The business has been through a difficult time in recent years, coming close to collapse in 2013.

Last year, it was one of two interested parties bidding to take over Banham Poultry, in Attleborough, which was eventually sold to Chesterfield Poultry.

In 2016 the Boparan Private Office, owned by food tycoon and 2 Sisters Food Group entrepreneur Ranjit Boparan, known as the “Chicken King”, bought the firm in a pre-pack deal in 2016 from Rutland Partners, saving 2,000 jobs after the firm posted pre-tax losses of £5.2m.
