Watchdog dashboard shows that for the last 7 days ended Nov 6, 2022, attacks using port 5432 have increased by 158% (as seen below). We have sent abuse alerts to the top networks where the attacks came from. In the chart below: Incrediserve LTD network is the most prolific source of attacks (5276 incidents representing a 1,470% increase over the prior 7 days).

We quickly identify the rogue source IP from Incrediserve LTD using Port 5432: (In this case: 89.248.163.199). We also note the increase in attacks by this IP over the last 7 days.

What exploits are on port 5432 ?
A quick check over at SANS Internet Storm center shows that this port is associated with PostGres database server. Apple also uses this for ARD 2.0 Database.

When we compare our dashboard results with worldwide stats, there is a slight increase in world wide attacks on PostGres. This typically means that there are exploitable vulnerabilities that may or may not be patched:

Punctuation Rules for Comma Use

Rule 1. To avoid confusion, use commas to separate words and word groups with a series of three or more.
Example: My $10 million estate is to be split among my husband, daughter, son, and nephew. Omitting the comma after son would indicate that the son and nephew would have to split one-third of the estate.
Rule 2. Use a comma to separate two adjectives when the word and can be inserted between them.
Examples: He is a strong, healthy man.
We stayed at an expensive summer resort. You would not say expensive and summer resort, so no comma.
Rule 3. Use a comma when an -ly adjective is used with other adjectives.
NOTE: To test whether an -ly word is an adjective, see if it can be used alone with the noun. If it can, use the comma.
Examples: Felix was a lonely, young boy.
I get headaches in brightly lit rooms. Brightly is not an adjective because it cannot be used alone with rooms; therefore, no comma is used between brightly and lit.
Rule 4. Use commas before or surrounding the name or title of a person directly addressed.
Examples: Will you, Aisha, do that assignment for me?
Yes, Doctor, I will.
NOTE: Capitalize a title when directly addressing someone.
